This study uses GIS to assess the extent of deforestation, forest degradation, and carbon stock in East Java, Indonesia. The dataset for this study required preprocessing and proper GIS analysis tools to track and quantify land cover changes, specifically deforestation and forest degradation from 1990 to 2022. The results show that East Java has experienced significant deforestation and forest degradation, with a total deforested area of approximately 180,000 hectares and a degraded forest area of around 270,000 hectares. Among the subregions, Malang had the highest deforestation rate, with a total area of 42,605 hectares, while Banyuwangi had the highest forest degradation, with around 64,782 hectares affected. Primary mangrove forest in East Java has decreased from approximately 15,000 hectares in 1990 to around 9,000 hectares in 2022. Furthermore, the study estimated the carbon stock changes over the study period. The total carbon stock in 1990 was around 196 million tonnes, but by 2022 it had decreased to approximately 156 million tonnes. The difference in carbon stock between 1990 and 2022 is approximately 40 million tonnes of carbon. Analyzing carbon stock with remote sensing and GIS will give faster results than the manual approach. These findings highlight the urgent need for effective forest management and conservation measures in East Java to mitigate further environmental degradation and carbon emissions. Integrating GIS-based forest monitoring techniques provides a valuable tool for assessing land cover changes and their impact on carbon stock, enabling informed decision-making for sustainable land use planning and conservation strategies.

Abstract Rawon is a meat-based soup from the east of Java characterized by its black color due to the use of keluak seeds. Rawon is prepared through the boiling of meat with sautéed spices. The use of various spices resulted in a unique Rawon flavor liked by many. Rawon has existed for over a thousand years and is still very popular today. The delicious flavor of Rawon is not only loved by the local people of East Java but is also nationally recognized as one of Indonesia's traditional culinary icons and is internationally recognized as one of the best meat-based soups in the world. Rawon is usually served with rice, side dishes such as salted egg, and tempe, and various condiments such as mung bean sprouts, sambal, and kerupuk. Thus, Rawon not only satiates hunger but is also highly nutritious. Nasi Rawon or Rawon rice can be consumed for breakfast, lunch, or dinner. Rawon originated as a royal dish; however, presently it can be found anywhere and is sold in many food stalls and restaurants. It manifests a philosophy that although the Indonesian archipelago consists of many different ethnic groups, a harmonious life can be attained when they unite and coexist. Furthermore, this dish contains the philosophy of “sugeng rawuh” as a greeting to guests; therefore, Rawon rice is commonly served at weddings and community events or activities. This paper discusses in more detail the history of Rawon (including its origin and philosophy), the nutritional aspects, the ingredients, the process of making Rawon, and the chemical reactions that take place in creating the delicious flavor of the dish. The discussion also addresses presentation and on what occasions Rawon is served.

Global competition has forced companies, including small and medium enterprises (SMEs), to improve their competitive advantage. Supply chain management practices are the ways to improve the competitive advantage, particularly in the global competition context. However, there is still doubt SMEs can compete globally, considering they face limited resources, skilled workforce, and business networks. Therefore, this study aims to examine the influence of supply chain management practices, covering cross-functional integration, partnership, responsiveness, and resilience. Moreover, this study has examined which practices dominate in improving competitive advantage. The quantitative study involved 445 SMEs located in East Java, Indonesia. The respondents are supervisors or higher levels and work in departments related to supply chain management, as they can provide the relevant information and possess complete knowledge of management practices. The data were collected via a questionnaire designed with a five-point Likert scale. The responses were analyzed using SmartPLS software 4.0. The results show that cross-function integration improves supply chain partnership, responsiveness, and resilience (β = 0.705, 0.382, 0.324; t-value = 25.177, 6.697, 5.783). Supply chain partnerships affect supply chain responsiveness, resilience, and competitive advantage (β = 0.327, 0.257, 0.249; t-value = 5.933, 4.536, 5.651). Moreover, supply chain responsiveness improves supply chain resilience and competitive advantage (β = 0.285, 0.106; t-value = 5.690, 2.099). Supply chain resilience improves competitive advantage (β = 0.435 and t-value = 8.987). SMEs can enhance their competitive advantage by integrating their internal cross-functional integration and adopting supply chain partnership, responsiveness, and resilience.

This study analyses land use and land cover (LULC) changes during the last five decades (1970-2021) in East Java Province, Indonesia. The changes are analysed by comparing four maps interpreted from Landsat images (MSS 1972, TM 1997, OLI 2013, and OLI 2021). The main research procedures consist of (1) data collection, (2) field survey, (3) image classification, and (4) LULC change interpretation. The classification uses the maximum likelihood algorithm, achieving an overall kappa accuracy of > 75%. The classification produces eight classes, i.e., built-up land (BU), heterogeneous agricultural land (HAL), bare soil (BS), paddy fields (PF), open water (OW), vegetation (VG), shrubland (SH), and wetlands (WL). The analysis shows a significant shift in land use from 1972 to 2021, with HAL declining by 46%, SH by 91%, and BS by 88%. In contrast, PF has increased by 105%, VG (forest and plantation) by 64%, and built-up areas by a remarkable 366%. These changes show a significant shift from dryland agriculture, shrublands, and barren lands to irrigated regions, vegetated areas, and urban growth. Furthermore, there are increases in water bodies due to the construction of several reservoirs to support water availability. In coastal regions, the development of inland aquaculture leads to a proliferation of wetlands (salt evaporation ponds, fish ponds, and rice-fish integrated farming). [ABSTRACT FROM AUTHOR]

The high number of people with disabilities is one of the problems faced by the Indonesian government, especially in Java Province. After West Java Province, East Java Province is in second place as the province with the highest rate of people with disabilities in Indonesia. Disabled people are people with physical disabilities such as not being able to walk, not being able to talk, not being able to see, and so on. The aim of this research is to group districts in East Java Province based on types of disabilities with the hope of facilitating activities in fulfilling the rights of people with disabilities in East Java Province. The grouping was carried out in order to determine the characteristics of each cluster therefore the optimal k-means method was used for clustering using the Euclidean distance method with cluster 1 in 29 districts and cluster 2 in 9 districts. The most optimal single linkage uses the Euclidean distance method with cluster 1 having 8 districts and cluster 2 having 30 districts. From the results of the validity index values, it was found that the single linkage method had the smallest validity value compared to the k-means method. [ABSTRACT FROM AUTHOR]

Purpose: Colorectal cancer (CRC) is a global malignancy with 10.2% of cases, ranking third in worldwide cancer cases. According to Indonesia Health Research, CRC's prevalence has risen significantly, reaching 1, 8 per mile in 2018, and reports rising cancer cases in the past 5 years. This study explores the relationship model between smoking, socioeconomics, and CRC, considering cultural moderation. Design/Methodology/Approach: Conducted as a retrospective study with 212 respondents, comprising 172 cases of left-sided colorectal cancer (left CRC ) and 40 cases of right-sided colorectal cancer (right CRC) from three cultural areas. Structural Equation Modeling (SEM) employing Warp-PLS was utilized for data analysis. Finding: A significant positive relationship was found between smoking and CRC prediction (β = 0,081, p-value = 0,040). This pattern also applies to socioeconomic status and CRC prediction (β = 0,311, p-value = <0,001). The influence of culture on both relationships is not the same. The relationship between smoking and CRC prediction is not influenced by culture (p-value = 0,318). Conversely, the relationship between socioeconomic status and CRC prediction is influenced by culture (β = 0,078, p = 0,047). Conclusion: Poor smoking habits and weak economic conditions influence the prediction of CRC negatively in East Java Province. Unfavorable cultural practices further worsen the relationship between weak socioeconomic status and poor CRC prediction in East Java Province. Recommendations suggest that preventing adverse CRC outcomes can be achieved through smoking cessation and improving socioeconomic conditions. Preventive efforts to enhance socioeconomic conditions should consider local cultural nuances. Research limitation: This research is limited to a population group in East Java Province, Indonesia, divided into three cultural areas: Mataraman, Arek, and Pendalungan. [ABSTRACT FROM AUTHOR]

This study analysed the changes in land use and land cover (LULC) in East Java Province by comparing two LULC maps interpreted from optical imagery. The images captured from 2015 to 2017 were selected to represent the initial LULC maps. Then, the images collected from 2020 to 2021 were considered the recent LULC maps. The input imagery was prepared using the Google Earth engine (GEE). The Random Forest algorithm was used for classification. In this study, eight significant LULC classes were categorised, i.e., built-up area (BU), heterogeneous-agricultural land (HAL), bare soil (BS), paddy field (PF), open water (OW), vegetation (VG), shrubland (SH), and wetland (WL). Next, the training samples were interpreted from Google Earth Pro. Then, the GEE satellite base map and the ground control points (GCPs) were collected. The collected GCPs were split into 70% training and 30% validation data. The results showed that significant LULC Change was more marked in the most urbanised areas (in and around the big cities), followed by LULC change in and around medium towns and rural areas. Four classes experienced an area increase, i.e., BU (+30.23%), HAL (+30.77%), BS (+24.52%), and PF (+14.36%). As a consequence, the other four classes compensated for the increase, i.e., OW (−32.79%), VG (−25.72%), SH (−6.59%), and WL (−25.53%). Regional development from 2015 to 2021 has increased built-up areas. Conversely, the development has reduced OW, VG, SH, and WL. The LULC changes have significantly changed the natural landscape to a human-dominated one.

This study aimed to determine the sustainability status offflying fish management in ecological, economic, technological, social and institutional dimensions with a multidimensional study of systems in the Pasongsongan waters. This research was carried out from September to October 2023 at the Coastal Fisheries Port Pasongsongan. The rapfish (Rapid Appraisal for Fisheries) method was applied to determine the condition of fisheries in an integrated manner and to evaluate the sustainability of fisheries in a multidisciplinary manner based on attributes and scores set. The sustainability index value of data processing was between 0 (bad) to 100 (good). The results of this study showed that the sustainability index of flying fish management in the ecological dimension fell within the sustainable category, with a value of 79.12. Similarly, in the economic dimension, the index was 81.19 and classified as sustainable. The technological dimension scored 76.9, placing it within the sustainable category as well. However, the social dimension recorded a value of 64.93, categorized as moderately sustainable, and the institutional dimension scored 55.31, also falling into the moderately sustainable category. The results of the rapfish analysis for the sustainability index of flying fish management in the multidimensional system obtained a value of 70.56, categorizing it as quite sustainable.

East Java is one of the seismically active regions in part of the Sunda Arc whose seismicity pattern must be studied. Therefore, a spatio-temporal analysis of seismicity between 2002 - 2022 in East Java has been conducted. This analysis aims to investigate the seismotectonic conditions in the East Java region over the last twenty years, especially the seismicity patterns associated with significant earthquakes in East Java. The analysis was carried out by quantifying the spatial and temporal variations of seismicity parameters using b-value and z-value. The used data used are earthquake data from the USGS earthquake catalog during 2002 - 2022 in the East Java region. The analysis was performed using the ZMAP 6.0 program code using the maximum likelihood method. The results of the temporal analysis of b-values show that almost all significant earthquakes in East Java were characterized by a decrease in b-values of up to 0.2. Spatially, the significant earthquake on 10 April 2021 was associated with a low b-value (0.9). Temporal z-value analysis shows that the significant East Java earthquake was preceded by a quiet period (positive z-value) between 4 - 5 years (2003 - 2008 and 2012 - 2016). Spatial analysis of the z-value in the last 7 shows an increase in the z-value before the significant earthquakes occurred on 16 July 2019, 18 March 2020, and 10 April 2021. Therefore, the results of this study indicate that the b-value and z-value potentially can be used as precursors of the significant East Java earthquake. [ABSTRACT FROM AUTHOR]

Pesantren and East Java (Jatim) share a mutualistic, symbiotic relationship in political and cultural spheres. Pesantren is a byproduct of East Javan culture and a voting platform for regional elections. This study aims to ascertain the elements that voters on Madura Island consider when selecting a candidate in the 2018 East Java Governor Election. A mixed method comprising qualitative and quantitative elements and logistic regression data analysis techniques was employed to accomplish these research aims. According to the study’s findings, voters consider four elements: job programs, political parties, pesantren politics, and support from the contemporary Muslim community. Concurrently, these four elements impact the Khofifah-Emil candidate team’s outcome. According to the logistic regression findings, the Khofifah-Emil candidate team’s pesantren political strategy is to increase the number of graduate networks and pesantren support

Pentagon capital is a term used to describe the five essential forms of capital: human, social, financial, physical, and intellectual. These five forms of capital play a crucial role in improving the performance of women entrepreneurs. Therefore, this study aims to analyze the effect of these five forms of capital on the performance of women entrepreneurs, both directly and indirectly, through the adoption of digital technology. The analysis was conducted in 38 regencies/cities located in East Java Province, Indonesia, and comprised 268 women entrepreneurs from various business sectors. Following this, the primary data source was collected through the distribution of questionnaires, and the partial least squares structural equation modeling (PLS-SEM) was utilized to assess both the direct and indirect effects of the observed capitals using SmartPLS 4.0 software. The results showed that only social capital had a direct and significant effect on the performance of women entrepreneurs. However, human, financial, physical, and intellectual capital were found to significantly affect the performance of entrepreneurs indirectly through the mediation of the adoption of digital technology. It is also expedient to acknowledge that among the observed variables, financial capital was found to be the most important (19%). These results offered practical understanding for women entrepreneurs on strategies to increase their business income and access loans from financial institutions and government assistance. AcknowledgmentThe authors are grateful to the Ministry of Education, Culture, Research, and Technology of Indonesia for funding this research.

Urban development, population growth, high traffic jams, and intensive disaster events are indicators of changing the landscape of the eastern area of East Java. Investigating these changes is vital for planning and environmental protection in the future. This study examines changes in land use and land cover (LULC) during the past 50 years in the eastern part of East Java from 1972 to 2021. The changes are examined by contrasting four maps derived from Landsat images (1972, 1997, 2013, and 2021). The following are the main study procedures: (1) data inventory, (2) field survey, (3) image processing and classification, and (4) interpretation of LULC changes. With Google Earth Engine, all photos are downloaded (GEE). Landsat image classification was completed using the maximum likelihood algorithm with an overall Kappa accuracy of>85%. Eight (8) major classifications are therefore produced by the classification: (1) the pavement or urban area (PUA); (2) heterogeneous agricultural land (HAL); (3) bare soil (BS); (4) paddy field (PF); (5) open water body (OWB); (6) vegetation/plantation (VG); (7) shrubland (SL); and (8) wetlands (WL). In the areas with rapid development, the LULC change is more pronounced, i.e., Pasuruan, Jember, and Banyuwangi Regencies. LULC change in and near mid-regency and the rural regions comes next. Over the past fifty years, regional growth has resulted in increases in PUA (+4.4 percent), PF (+12.2 percent), and VG (+17.9 percent). On the other hand, the development has decreased SL, BS, and HAL by 5.8 and 15.9 percent, respectively (-13.1 percent ). LULC alterations for human activities have profoundly altered the natural landscape.

Tourism in Indonesia plays a crucial role as an economic sector with the potential for increasing foreign exchange earnings. Batu City, known as a tourist destination, offers various business opportunities related to tourism. Kampoeng Kidz, an educational land in Batu, holds potential as a sustainable tourism destination with its nature-based learning programs and scenic beauty. However, Kampoeng Kidz faces challenges in digital marketing, particularly during the pandemic, which resulted in a decline in visitor numbers. This research aims to develop a digital marketing strategy, with a focus on social media, to enhance visibility and visits to Kampoeng Kidz. In the context of Law No. 10 of 2009 on Tourism, this study highlights the role of tourism in economic development and provides a rationale for the urgency of digital marketing development. The research employs a qualitative descriptive method with the Branding Gelder theory approach. This approach allows for the reduction of irrelevant information, selecting only interesting, important, and useful information (Sugiyono, 2016). The study was conducted at Kampoeng Kidz using data collection techniques such as interviews, documentation, and observation. Data analysis involves data reduction, data presentation, and drawing conclusions. Tourist visit data to attractions in Batu City in 2020 indicate that Kampoeng Kidz had a relatively low number of visitors compared to other tourist attractions. The focus on educational tourism and its pre-pandemic recognition provide the basis for this research. Kampoeng Kidz needs to strengthen its digital marketing, especially through social media, to reach a wider audience. [ABSTRACT FROM AUTHOR]

Background: The prevalence of stunting in East Java Province in 2022 reached 19.2%, showing a decrease compared to 2021, which recorded a prevalence rate of 23.5%. Despite the declining trend in stunting prevalence in East Java, the province has not yet achieved the Renstra target, which stipulates that the prevalence of stunting should decrease to 18.4% by 2022. Objectives: This study aims to investigate further the causes of stunting incidents in East Java Province. Methods: The method employed in this research is a literature review, where data sources are obtained using the Google Scholar electronic database. The research search process follows the PICOS protocol, formulating keywords using Boolean Operator techniques. The keywords used are "factors" AND "causes" OR "relationships" OR "risks" AND "stunting" AND "infants" OR "toddlers" OR "children." The selection of studies to be included in the review is adjusted to inclusion criteria: studies published in the last ten years (2013-2023), written in Indonesian and English, full-text, published, and open access. Exclusion criteria include age range, non-observational research, and studies that do not discuss the causes of stunting. Results: A total of 13 studies were used in compiling this review. The location characteristics of the studies were found in 10 Districts/Cities in the East Java Province. Over the past ten years, various factors have been recognized as causes of stunting based on the identified research publications. These factors include parenting styles, Clean and Healthy Living Behavior (PHBS), economic status, educational history of birth, history of infectious diseases, and maternal pregnancy history. Conclusions: The primary research focus on stunting incidents in toddlers in East Java Province is the parenting style provided by mothers. The level of maternal knowledge regarding Exclusive Breastfeeding (ASI), provision of Complementary Feeding (MPASI), and the intake of foods consumed by toddlers has a significant correlation with the occurrence of stunting and the developmental progress of children.

The IUCN Red List classifies the green tree frog (Rhacophorus reinwardtii) as a frog that is Least Concern. One study that has never been carried out in Indonesia concerns the spatial distribution of the green tree frog based on Geographic Information System (GIS) applications and the habitat characteristics in East Java. It is vital to map the spatial distribution of the green tree frog in East Java and identify its habitat characteristics because the amphibian diversity surveys that have been conducted so far are the only ones available. This study is quantitative descriptive in design, with studies of pertinent literature as supporting sources. Cruising and the Visual Encounter Survey (VES) method are the techniques employed. A Geographic Information System (GIS) application is utilized in the computational method to create a spatial distribution analysis by gathering information on the locations of interactions with green tree frogs. Based on findings from studies conducted in the Bromo Tengger Semeru National Park Area (TNBTS), the Tancak Kembar Waterfall Area in Bondowoso Regency, and the Ironggolo Waterfall Area in Kediri Regency, there are 16 green tree frog meeting points recorded on the iNaturalist application for the Our Reptile Amphibian Observation Movement (GO-ARK) project and 3 points from the outcomes of field observations. In East Java, environmental factors such as altitude, slope, rainfall, NDVI, land cover, and proximity to rivers have a significant impact on how green tree frogs are distributed spatially. Although green tree frogs in East Java frequently forsake water bodies and choose to live in high-level plant types, they also frequently occupy a variety of water bodies. The green tree frogs discovered at the research location are categorized as favoring continuous habitats with boundaries for colony development. [ABSTRACT FROM AUTHOR]

The Rural Bank (BPR) plays a crucial role in the Indonesian banking industry, particularly at the regional level, serving as an alternative financing source for the unbankable population. This research aims to analyse the productivity levels of BPRs in East Java using the Malmquist Productivity Index (MPI) during the period from 2016 to 2022. The study sample comprises 30 BPRs in East Java. The analysis results indicate that the productivity of BPRs in East Java fluctuates from year to year. Moreover, during the COVID-19 pandemic, BPR productivity experienced a significant decline. The study provides recommendations for BPR management and regulators to pay more attention to BPR productivity and decision-making foundations. [ABSTRACT FROM AUTHOR]

Understanding the population data of a region is crucial for policy development and strategic planning. East Java Province, the second-largest province in Indonesia, has undergone significant population growth from 2021 to 2023. Uneven growth poses challenges in resource and infrastructure management. The K-Means algorithm clusters population data into several groups based on specific characteristics. The Elbow method is used to determine the optimal number of clusters, ensuring the accuracy of the analysis. This research aims to analyze and cluster the population distribution in each city in East Java Province, providing a more detailed and accurate depiction. The research findings reveal three significant clusters. Cluster 0 includes 21 towns, Cluster 1 comprises 4, and Cluster 2 encompasses 13. These findings have important implications for targeted development policy formulation at the city level in East Java Province. Additionally, this study contributes to the development of demographic analysis and population management, using valid methods and consistent results between RapidMiner and manual calculations. In conclusion, this research provides a solid foundation for more effective development policy formulation in East Java Province, offering essential information for sustainable population management.

The National Medium-Term Development Plan (RPJMN) for 2015-2019 and RPJMN for 2020-2024 emphasizes infrastructure development as the key to accelerating economic growth, especially through the implementation of a 2,500 km new toll road construction program. This program includes monumental projects such as the Trans Java Merak-Banyuwangi and Cikampek-Palimanan (Cipali) toll roads, which are the longest toll roads in Java. Evaluation of toll road development, in accordance with Government Regulation (PP) No. 39/2006, is a crucial step in assessing the success of public policy. However, PP No. 15/2005 emphasizes that the purpose of highway projects is to support economic growth and equitable development. In-depth research focused on the impact of the Trans Java toll road on economic growth in East Java. The results show the complexity and variation in the impact, with some toll roads increasing economic growth, while others decrease it. While theory suggests that infrastructure can accelerate economic growth, toll road development in East Java does not have an overall positive impact. Factors such as poor accessibility, high toll fees, and a lack of supporting infrastructure may be to blame. This impact is reflected in the decline in East Java's economic growth from 9.87% to 4.34% two years after toll road construction.

In the past two years, market information and the distribution of agricultural products have been affected by the COVID-19 pandemic, which has limited the distribution of information and the movement of agricultural products. As a result, the COVID-19 pandemic can lead to non-competitive behavior among intermediary traders, especially those operating in concentrated markets. This research aims to analyze the price volatility of horticulture commodity during the pandemic in East Java, Indonesia. The research data was collected through the official website of the Information System for Availability and Price Development of Basic Necessities in East Java (SISKAPERBAPO). The method used to analyze the impact of COVID-19 on horticultural agricultural product prices is ARCH (Autoregressive Conditional Heteroscedastic) and GARCH (Generalized Autoregressive Conditional Heteroscedasticity). The volatility results show that the prices of chili and shallots often fluctuate with high and unpredictable variations. However, the fluctuations in the prices of these two commodities are not due to a lack of supply or high demand, but rather due to the characteristics of these commodities, which are perishable and highly dependent on the season of production. The lower the quality, the lower the price will be. The price of shallots is relatively stable compared to chili due to its longer shelf life and less depreciation. The constraint faced by farmers of these two commodities during harvest time is the lack of storage facilities to store their harvest, forcing them to sell all their produce to middlemen or traders, which is one of the causes of the fluctuation of commodity prices.

Drought known as ‘silent killer’—unpredictable slow-moving hazard which cause severe damage to people and environment. Since agriculture is the first and foremost sector affected by drought, the risk of crop failure can be minimized by reducing vulnerability. Climate patterns can be considered as systematic conditions which are capable of assigning sensitivity regions to drought. Here, the study employs Oldeman’s Agro Climatic data as physical vulnerability indicator to assess and monitor the vulnerability of agriculture system to drought in East Java. The study used long-term monthly rainfall observation data to generate climatic map accompanied with socio-economic indicators to assess vulnerability of region to drought. Spatial distribution of vulnerability was mapped using Geographic Information Systems (GIS) combined with Analytic Hierarchy Process (AHP). The results show there are five categories of vulnerability to drought: very high, high, moderate, low, and very low based on standardized index. Madura Island, particularly Bangkalan, Sampang, and Sumenep considered as most vulnerable region to drought. In addition, most regions in the north plain of East Java, including Tuban, Lamongan, and Gresik categorized as highly vulnerable to drought. Factors affecting vulnerability are mostly related to drier climate which affect acreage and availability of irrigation. The socio-economic factors likewise smallholder farmers and poverty contribute to rising vulnerability level. South part of East Java, particularly Tulungagung and Blitar Regency was least vulnerable because of appropriate climate which induced to acreage of irrigated land. The study emphasizes the utilizing of Oldeman climate pattern as primary indicator in determining vulnerable regions. Smallholder farmers and poverty causing vulnerability in agriculture emerged as priority for further study. The results can provide new insights into drought management for most vulnerable regions by considering local climatic characteristics.

Background and Aim: Various methods can detect foot-and-mouth disease (FMD) in cows, but they necessitate resources, time, costs, laboratory facilities, and specific clinical specimen submission, often leading to FMD virus (FMDV) diagnosis delays. The 2022 FMD outbreak in East Java, Indonesia, highlighted the need for an easy, inexpensive, rapid, and accurate detection approach. This study aims to devise a one-step reverse transcriptase loop-mediated isothermal amplification (RT-LAMP) technique and phylogenetic analysis to detect the serotype O FMDV outbreak in East Java. Materials and Methods: Swab samples were collected from the foot vesicles, nasal secretions, and saliva of five suspected FMDV-infected cows in East Java between June and July 2022. The RT-LAMP design used hydroxy naphthol blue dye or SYBR Green I dye, with confirmatory analysis through reverse transcriptase polymerase chain reaction (RT-PCR) targeting 249 base pairs. PCR products underwent purification, sequencing, and nucleotide alignment, followed by phylogenetic analysis. Results: The RT-LAMP method using hydroxy naphthol blue dye displayed a positive reaction through a color shift from purple to blue in the tube. Naked-eye observation in standard light or ultraviolet (UV) light at 365 nm, with SYBR Green I stain, also revealed color change. Specifically, using SYBR Green I dye, UV light at 365 nm revealed a color shift from yellow to green, signifying a positive reaction. Nucleotide alignment revealed mutations and deletion at the 15th sequence in the JT-INDO-K3 isolate from the East Java FMDV outbreak. Despite differing branches, the phylogenetic tree placed it in the same cluster as serotype O FMDV from Malaysia and Mongolia. Conclusion: JT-INDO-K3 exhibited distinctions from Indonesian serotype O FMDV isolates and those documented in GenBank. Then, the RT-LAMP method used in this study has a detection limit 10 times higher latter than the conventional RT-PCR limit, without any cross-reactivity among strains.

Infectious diseases are a problem that is still a challenge and has not been resolved in Indonesia. The number of infectious disease cases continues to increase every year in Indonesia. Infectious diseases that are still a problem in Indonesia include tuberculosis (TB), pneumonia and leprosy (Leprosy). Identification of infectious disease endemic areas is an important issue in the health sector, the average rate of people with physical disabilities and deaths originating from infectious diseases. Indonesia, as a country consisting of 34 provinces, including East Java as one of the provinces that has a high rate of infectious disease cases. Therefore, research was conducted using correspondence analysis which aimed to determine the pattern of infectious disease trends and grouping districts / cities in East Java Province based on similarities between the spread of disease sufferers in each district / city. This type of research uses quantitative methods with secondary data obtained from the Central Bureau of Statistics of East Java Province. The results of correspondence analysis show that the spread of pneumonia and tuberculosis in East Java Province has a relative tendency to almost all regencies/cities in East Java, while the spread of leprosy is closer to Sampang Regency. From this research, it can be used to supervise and control infectious diseases in districts / cities in East Java Province, so that the government can adjust policy formulation and actions to prevent an increase in infectious disease cases in East Java

The manufacturing industry’s contribution to East Java’s economy is high. Still, the trend continues to decline, while the contribution of the trade, hotel, and restaurant sectors is increasing. This indicates that there has been a shift in the economic structure from industry to trade. This research uses a quantitative approach based on the classification carried out by UNIDO (United Nations Industrial Development Organization) and the World Bank. The results of secondary data from Central BPS and East Java Province BPS show that East Java Province is categorized as a semi-industrial area. East Java’s industrial development is experiencing a decline from the “semi- industrialization” stage to the “towards industrialization” stage. This is an early indication of a decline in industrialization or deindustrialization in East Java. If the stages of industrialization in East Java have decreased, but not for commodity industrialization (the ratio of the manufacturing industry’s contribution to the commodity sector). The value of commodity industrialization continues to increase. The commodity sector includes agriculture, mining, industry, construction, electricity, gas & drinking water.

Spiritual tourism prioritising religious aspects, is one of East Java’s oldest forms of tourism, especially in Malang district. This form of tourism has long developed since combining Islamic and Javanese values. The concept emerged along with the Indonesian halal tourism brand. As a form of contribution to the development of religious tourism, this study seeks to show the existence of traditional relations in aspects of Islamic pilgrimage as a form of tourist behaviour which involves visiting historical tourism in tourist villages. This research uses a qualitative methods with a case study which includes interviews and participatory observation that aims to understand the aspects of pilgrimage in depth. The findings show that tourists visiting spiritual objects of high importance are not unlike Muslims in their behaviour when visiting Mecca - performing tawaf, drinking holy water, giving alms and eating together. However, this is something that attracts tourists to visit. Planning and development are still needed, especially in the flow of rituals that are carried out so as not to eliminate the purpose of developing halal tourism in Indonesia.

In 2020, the freedom of religions in Indonesia reached lowest point which accounts for the score of 1 out of 4. This decreasing trend is in line with some intolerance cases as happened recently. Intolerant groups are often linked with fundamentalism or scriptural Islamic groups taking their movements in the form of persecution, oppression, violence provoked by religion and tribe. The issue is inextricable from how this violence is triggered by anti-tolerant ideology living amidst the society within the state and the politics of Indonesia. This research was conducted in 38 regencies/municipalities in East Java Province, Indonesia. The methods employed in the research involve survey based on descriptive-quantitative approach. The survey adopted religious tolerance measurements developed by Broer et al. The research reveals that Religious Tolerance Index in East Java is considered good. However, religious conviction scored low, with the average score of 62.1. It becomes one of the contributing factors on the intolerance towards minority groups. Furthermore, religious conviction is deemed to be quite strong to determine the level of conservatism in the society to treat their social life.

Institutionalization of petty corruption among farmer households in the villages around the forest has focused on large and productive state forest areas managed by the State Forest Company (SFC). The activities occurred simultaneously. There is no data to reveal the activities. This research aimed to analyze how the corrupt mechanism transpired. A qualitative method was induced to detail the occasion of petty corruption at the teak stands. In-depth interviews with key informants, participatory observation, and Focus Group Discussion (FGD) with local communities demonstrated that marginal teak forests in Java, or at least in Lemah Gurih, are not accidental but seem “intentional” to support illegal logging practices. SFC’s conservatism in setting wood standards oriented to the global market’s needs and not adjusting to the increasing local market demand for teak wood triggered corruption. As a result, local forest officials can trade those wood products as personal income without violating company regulations. Simultaneously, together with the illegal wood collectors (IWCs), they also manipulate the calculation of timber yields to get unilateral benefits. The corrupt behavior is continuously institutionalized over generations by patron-client relationships, and they have become an integral part of the lives of local communities. The recommendation to reduce corrupt behavior is to improve forest management practices, a review of wood harvesting administration, wood quality standards, and changes in social relations between SFC and local communities to be a more formal relationship are critical.

Smallholder farmers and their agroecosystems in active volcanic landscapes need to deal with and recover from eruptions. Resilience to extreme shocks may increase with system diversity, enhancing food and income security and ecosystem services provision; however, the longer term effects of volcanic ash are rarely assessed. To test the hypothesis that tree diversity contributes to the social–ecological resilience of coffee-based agroforestry, we quantified (1) the immediate effects of deposition of a 15-cm ash layer on tree survival, (2) the effect of volcanic ash on aboveground C stocks, tree diversity and wood density frequencies, (3) litter layer dynamics, and (4) farming system and income recovery 3 years after. Observations in four land-use systems before and after ash deposition (remnant forest, coffee-based complex and simple agroforestry, annual crops) were complemented by 46 farmer interviews on tree species' survival, system, and financial recovery. Based on farmer interviews, low-wood-density trees were most affected by volcanic ash deposition. Ash deposition did not, after 3 years and across land-use systems, significantly change tree density, basal area, or C stocks. In contrast, species richness in coffee-based agroforestry increased significantly. Standing litter stocks in agroforestry decreased, but slower decomposition partially compensated for reduced litter input. Farmers stated that diversity and flexibility in coffee-based agroforestry support a system recovery that is faster than that for annual crops, suppressing income fluctuation. Farmer's adaptive responses to enhance species diversity contributed to the resilience of farms, by retaining basic system structure and functions of agroforestry, and increasing product diversity and income.

This study investigates the characteristics of potentially toxic elements in soils collected from the vicinity of a lead smelter in East Java, Indonesia. The objective is to assess the impact of the lead smelter on the surrounding soil. The study involves chemical composition analysis, spatial distribution mapping, and potential ecological and health risk assessments. Soil samples were collected from the surface area (0–10 cm) and subsurface (15–30 cm) within radii of 1.5 km, 3 km, and 5 km from the lead smelter. The samples were analyzed for As, Cr, Cu, Ni, Pb, and Zn using energy-dispersive X-ray fluorescence. Principal component analysis (PCA) was performed to identify the sources of potentially toxic elements in the soil. The results indicate severe Pb contamination within a 1.5 km radius of the smelter, with an average contamination factor (Cf) value of 22.0, posing a high potential health risk. The contamination factor indicated that the soils were heavily polluted by As and Pb and moderately polluted by Cu, Ni, and Zn. The results of PCA showed that smelter releases are the main source of potentially toxic element contamination in the soil, accounting for 66.2%. The health risk assessment suggested that the children and adults in the study region were exposed to non-carcinogenic risks caused by As and Pb. Oral ingestion was identified as the primary exposure route impacting health risks. The carcinogenic risk from potentially toxic elements in soil was found to exceed the acceptable level for children and adults in the study region. Therefore, it is necessary for the government to take effective measures, including designing regulations and interventions, and improving lead smelter management to mitigate potential contamination and minimize the impact of lead smelter releases on the surrounding environment, especially to protect human health, particularly that of children.

Introduction: As a tropical country, Indonesia's climate is hot and humid throughout the year, implicating hot workplace environment and leading to workers' susceptibility to heat stress exposure. Workers at a steel processing mills exposed to an extremely hot environment are prone to experience heat stress-related symptoms caused by occupational heat stress. Methods: The study aimed to build a predictive model of heat stress-related symptoms in steel mill workers based on physiological and environmental parameters. The respondents of this study were 119 operators exposed to a hot workplace in Surabaya, Sidoarjo, and Gresik, East Java, Indonesia. Results: The result as a high correlation (p<0.05) in predictive between the model Wet Bulb Globe Temperature (WBGT), core body temperature, heart rate and heat stress-related symptoms with R-value of 0.78 or 78%. In addition, there is a weak correlation between heat stress symptoms and systolic and diastolic blood pressure, as well as humidity factors and heat stress-related symptoms. Heat stress-related symptoms have a linear correlation with the value of WBGT, body core temperature and heart rate, while body core temperature has the highest value of correlation and WBGT is attributed to the lowest of all to the heat stress-related symptoms. Conclusion: With these values in hand, ones can predict whether workers will be exposed to heat stress work environment. Furthermore, with this model, it can predict heat stress-related symptoms in a particular workplace. [ABSTRACT FROM AUTHOR]

Surono Gondo Taruno's shadow puppet (wayang kulit) performance has a distinctive cross-style, making him a famous puppeteer in East Java. Accordingly, this discussion seeks to answer the question, "What is the cross-style of Surono's wayang figures in the Wahyu Wijaya Kusuma play? This discussion uses a qualitative method with Sunardi and Umar Kayam's cross-styled approach. Observational and interview-based were analyzed descriptively and qualitatively. The study results indicate that Surono's performance uses a cross-styled approach between the Surakarta style as the dominant style and the East Java and the Yogyakarta styles as the supporters. Surono's cross-style has made his performance attractive to contemporary spectators.

Background: Dengue Hemorrhagic Fever (DHF) is one of the endemic diseases throughout the tropics and parts of the subtropics. One of the provinces that felt the impact of the dengue outbreak was East Java. Overall, villages implementing STBM coverage in East Java Province is good but incidence of DHF is still found in all districts or cities in the last 3-year period. Purpose: This study aims to analyze the relationship and the inclination tendency of Dengue Hemorrhagic Fever in East Java). Methods: This type of research is an observational study with a cross-sectional study design. The sample population used 38 regencies/cities in East Java Province. The data used are the health profile data of East Java Province in 2018, 2019, and 2020. The data analysis technique used descriptive by utilizing the Health Mapper application version 4.3.0.0 with product version 4.03. Results: The distribution of DHF incidence with the coverage of villages implementing STBM East Java in 2018, 2019, 2020 showed decrease the coverage of villages implementing STBM is also followed by an increase DHF cases every year. The coverage of villages that implement Community Based Total Sanitation (STBM) fluctuates every year. Conclusion: Areas with STBM villages cannot guarantee DHF-free zones but can prevent the transmission of Dengue Hemorrhagic Fever (DHF) by changing hygiene and sanitation behavior through community empowerment to create a good sanitation.
