Background: Stem cells have been widely used in various fields of the health sector, one of which is dental health. Teeth with malocclusion require orthodontic treatment to achieve good function and aesthetics. Orthodontic tooth movement (OTM) occurs due to a bone remodeling process, namely deposition in areas of tension and resorption in areas of pressure. Differentiated stem cells are thought to influence OTM through several different mechanisms. Purpose: This narrative review seeks to explain how stem cells affect the mobility of orthodontic teeth. Review(s): OTM is aided by inflammatory mediators that are produced as a result of the induction of stem cells in the periodontal ligament. These mediators control osteoclast and osteoblast differentiation and proliferation, as well as bone remodeling. Periodontal ligament stem cells (PDLSCs) are important local immune response modulators in the inflammatory milieu and have an impact on a range of immune cells. Conclusion: PDLSCs, which are included in mesenchymal stem cells (MSCs), play a role in OTM through various mechanisms that can cause acceleration in OTM.

Education is one of the important factors to support one's future. Madrasas are one of the places of education that currently tend to be an option. This existence is caused by religious values ​​which are more emphasized in madrasas. In madrasa students are expected to be independent and achieve, in accordance with the slogan of the madrasa itself. Independent is meant to be able to know, recognize himself and then be able to develop himself. While the word 'achievement,' has the meaning of an effort from independence and proud performance. However, observations at the An-Nur Foundation found that further guidance was needed to shape the character of Madrasah Ibtidaiyah students who were independent achievers. This research was conducted using the Community Based Research (CBR) method, which is a research conducted with the community in solving the problems they are experiencing. The emergence of CBR begins with the development of relationships between researchers and community organizations that jointly carry out research activities using scientific methods and community-based approaches. The results of this study are in the form of a pocketbook entitled Majmu>‘a>t al-Adhka>r wa al-S}alawa>t (A Collection of Remembrance and Salawat) which is a summary of a series of madrasa activities at the An-Nur Foundation. The existence of this pocketbook is expected to be able to assist in carrying out the existing series of activities.

East Nusa Tenggara Province is one of the provinces in Indonesia in the form of an archipelago and geographically borders directly with the State of Timor Leste. This province has a problem with a fairly high poverty rate, in fact it was recorded as the 3rd highest in Indonesia after the provinces of Papua and West Papua. Because it is an archipelagic province, the problems of disparity in regional development, income inequality and poverty cannot be avoided. The existence of this disparity symptom does not only lie in regional development, but this disparity occurs in the income and GDP-forming sectors. Therefore the main goal to be achieved in this research is to identify areas in NTT Province which are still classified as lagging behind, and how to find the economic base sector as a leading sector so that it can be used as a locomotive for regional development so that in turn it is able to reduce regional inequality, income distribution and poverty. The analytical tools used are Theil Entrophy Analysis, Klasen Typology, Location Quintient (LQ) Analysis and Dynamic Location Quintien (DLQ) Analysis. The data needed is secondary data in the form of published documents from the BPS Province of NTT from 2012-2018 for the purposes of analysis such as GRDP data, population and per capita income for each district in the province of NTT. The results of the analysis found that there were 3 regencies that were classified as developed and fast growing, 3 regencies which were categorized as developed but depressed areas.

The poverty problem is a multidimensional discourse. The debate about poverty and how to exterminate it has been carried out for many years. This is important because the problem of poverty can have implications for social, economic, and political problems in society. In fact, in the hadith the Prophet Muhammad SAW stated that "Poverty (Poverty) is close to kufr". In Islamic history, one scholar who discussed poverty was Ibn Khaldun. Referring to the socio-economic dynamics theory compiled by Umer Chapra based on Ibn Khaldun's thoughts in his "eight wise principles" or Hikammiyah sentences, Ibn Khaldun views poverty as not only caused by economic factors but also influenced by multidimensional non-economic aspects (morality). This study aims to observe the influence of Ibnu Khaldun's social-economic dynamics, such as government spending in the social sector, corruption, human development index (HDI), Gross Regional Domestic Product (GRDP), Foreign Direct investment (FDI), and Gini ratio over poverty rates in Indonesia. This study used modeling using the static panel data regression method with the Generalized Method of Moments (GMM) approach. Based on panel data analysis which includes data from 34 provinces in Indonesia for the 2018-2022 period, it was found that the variables of government spending in the social sector, corruption and Gross Regional Domestic Product (GRDP), significantly affect the poverty rate in Indonesia. Meanwhile, the variables Human Development Index (HDI), Foreign Direct investment (FDI), and Gini ratio have no effect.

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.

This article contains the discussion of the history and the preservation of The Old City of Semarang. The Old City was founded at the end of 17th century after an agreement was approved by the Mataram Kingdom and the Vereeniging van Oost-Indische Compagnië (VOC) in 1678. Later on, the colony of VOC developed into a little city surrounded by a fortress in which VOC leaders, its officers, VOC soldiers, European traders resided. Here, some town facilities were built such as municipality house (stadshuis), shops, roads, soldier barracks, warehouses, schools, hospital, church, court, prison, and municipality park. Around the third decade of the 19th century, the fortress of VOC colony was demolished since this city was massively developed. Today, this little city built by VOC is called “Semarang Old City” or “De Oude Stad” (in Dutch), and the municipal government of Semarang is eager to protect and develop this cultural heritage site as a tourism cultural asset due to its unique values and typical cultural attractions. The purpose of this study is to support the Semarang City Government’s plan to propose The Old City of Semarang to UNESCO in order to get recognition as a World Heritage.

This research focuses on the efforts of a Javanese dance sanggar (studio or training house for Javanese Dance), Sobokartti, that was established in the early twentieth century in maintaining the existence of Javanese traditional performing arts. Amidst the storming cultural menu offered by technology facilitation, traditional performing art faces difficult challenges. The concern that the traditional performing art will be shifted by cultures that are considered more modern is inevitable and indeed proven in line with the course of globalization. The existence of traditional performing art was worrisome when Covid-19 pandemic emerged that restricted people’s movement throughout the world. This research used qualitative method by emphasizing observation during online and offline performances. Observation was also performed by visiting social media accounts that were related to Sobokartti. This research attempted to answer two questions. First, how does Sobokartti maintain its existence during the Covid-19 pandemic; and Second, how does Sobokartti adapt to the advancement of technology in the globalization era. The results of this research show that Sobokartti successfully maintained its existence, among others, due to its adaptive management system to changes through times and the awareness of performing innovations in training and promotional activities. Finally, social media have become one of the media used by Sobokartti in preserving Javanese traditional performing arts, especially Javanese dance. The use of social media for promotion media has succeeded in maintaining Sobokartti as an institution for preserving the traditional Javanese arts.

The biodiesel production by transesterification method has five stages, namely: (1) the preparation process; (2) the transesterification process, (3) the separation process, (4) the washing process; and (5) the drying process. Separation occurs independently using a split funnel and gravity force, which takes approximately 120 minutes. The length of this separation process makes it less time efficient in the biodiesel production process. Therefore, a centrifuge separates FAME and glycerol while accelerating the process. This study aimed to determine the quantity and quality of biodiesel made from CPO and VCO using centrifugal speed and separation time variations. The rotation speed is varied between 2000 rpm and 4000 rpm, while the separation times are 5 minutes and 10 minutes. The result showed that the highest quantity of biodiesel from CPO and VCO was obtained using high centrifugation speeds of 4000 rpm and a 10-minute separation. The result showed biodiesel produced with this variation has good quality which met with SNI.

The COVID-19 pandemic has impacted every element of adolescent life worldwide, including Indonesia. This study intended to examine how adolescents' loneliness and mental health during the COVID-19 pandemic are affected by their family relationships and online friendships. This study collects data using an online questionnaire. The Mental Health Continuum-Short Form, the UCLA Loneliness Scale Version 3, the Brief Family Relationship Scale, and the Online Friendship Scale were used to collect the data. Two hundred ninety-two students aged 12-18 participated in data gathering in Jakarta, Indonesia, between March and April 2021. Descriptive, correlation and Structural Equation Modeling (SEM) analyses were conducted using SPSS 25.0 and LISREL 8.80. This research revealed that family relationships and online friendships had a negative effect on loneliness. Family relationships favorably impact adolescent mental health, but loneliness negatively impacts it. Furthermore, family relationships and online friendships indirectly affect adolescents' mental health through loneliness. These findings may implement in developing interventions to assist adolescent mental health during the COVID-19 pandemic in Indonesia.

Rosin and turpentine oil are commercially developed non-timber forest products generated from pine oleoresin. In Indonesia, the Quarre method is utilized to tap manually or motor-manually (using handheld tapping machines). Handheld tapping machines can greatly boost productivity on the work, but they may also pose serious risks to workers’ health. This study aimed to examine the work-related musculoskeletal disorders (WMSDs) risk of motor-manual tapping by using four postural analysis instruments: Natural Range of Motion (RoM), Rapid Entire Body Assessment (REBA), Rapid Upper Limb Assessment (RULA), and the Ovako Working Posture Analyzing System (OWAS). In addition to the finding that the use of handheld machines is associated with a high WMSDs risk level, particularly in the work element of renewing the tapping faces, this study demonstrated that RULA is a postural-based risk level instrument with the highest level of sensitivity when being used to assess risk levels in tapping activities involving a great deal of upper limb movements. Despite the widespread use of OWAS for emergency corrective action, this study demonstrates that OWAS has a very low level of sensitivity. For this reason, we stress the importance of using a wide range of instruments for risk assessment to get more accurate results. Keywords: Musculoskeletal disorders, pine tapping, postural analysis, risk level

The purpose of this paper is to describe the natural potential of Gentan Village, analyze the opportunities, challenges, strengths and threats in an effort to organize and develop Gentan Village as a nature-based tourism village. This paper uses a qualitative descriptive method that relies on observational data, qustionnaires and interviews with three different social classes of people in Gentan Village. The purposive technique was chosen in taking samples of three informants consisting of community leaders, tourists and local residents. The results of this study indicate that the low index of human resources of the Gentan Villager has influenced their perception on the conservation, management and utilization of cultural heritage sites. Changing the perception of Gentan Villager into a society that is aware on developing cultural heritage into a natural tourism village (geoheritage) requires the participation of many stakeholders. The conclusion of this research was the perception of Sukoharjo Gentan villager doesn’t reflect as a community who has attention to its cultural heritage and doesn’t oriented to make its village to be natural tourism destination.

Starting in May 2021, green building is mandatory for new buildings in Indonesia. Greenship is a green building certification system in Indonesia issued by the Green Building Council Indonesia (GBCI) which is a member of the World GBC for the conservation and efficiency of resources (energy, water, land, materials, and nature). Greenship will be implemented in MICE which is a building for Meetings, Incentives, Conventions, and Exhibitions that has a strong economic attractiveness in Indonesia, which has a population of 270 million. Using the SEM-PLS it was quickly concluded that energy is the most influential factor in achieving platinum ratings from GBCI.With the value engineering (VE) method and life cycle cost analysis (LCC), it is needed an additional 4,689% cost for the platinum grade green costs through energy optimization will get a payback period of 3 years and 10 months. The novelty of this research, since the design, it is necessary to take steps to measure energy efficiency and other resources with a selection of materials/machines and working methods of the green concept to know the amount of additional initial costs that do not much burden investment costs compared with some future benefits of green MICE.

Indonesia kaya dengan berbagai macam tanaman diantaranya buah pisang yang mempunyai beragam jenis. Untuk mengetahui tingkat kematangan pada suatu jenis pisang biasanya dilihat dari warna, akan tetapi karena faktor usia dan kelelahan dari para petani biasanya sering terjadi kesalahan pada saat pengukuran akurasi. Penelitian ini bertujuan untuk mengklasifikasi jenis pisang berdasarkan citra warna dengan menggunakan algoritma Support Vector Machine (SVM). Data yang digunakan adalah citra pisang dengan total 1256, yang diklasifikasi menjadi 2 jenis pisang, Pisang ambon dan Pisang lady finger. Hasil yang didapat dari penelitian ini ditunjukan oleh confusion matrix dengan nilai True Positive (TP) = 0,82 dan False Positive (FP)= 0,18. serta False Negative (FN) = 0,02 dan True Negative (TN) = 0,98. Dari nilai yang ditunjukan oleh confusion matrix dapat diartikan bahwa algoritma SVM cukup baik digunakan dalam mengklasifikasi jenis pisang sehingga dapat memberikan jaminan mutu atas produk yang dihasilkan oleh petani.

HIGHLIGHTS 1. To provide effective prevention and management of placenta previa, maternal and neonatal outcomes should be identified. 2. Among mothers studied, no maternal mortality was found, but most newborns had prematurity and low birthweight. ABSTRACT Objective: To identify maternal and neonatal outcomes in delivery with diagnosis of antepartum hemorrhage (APH) due to placenta previa. Materials and Methods: This was a descriptive retrospective study with cross-sectional design. Samples were taken using medical records with convenience sampling technique. Deliveries with history of APH due to placenta previa at Dr. Soetomo General Academic Hospital, Surabaya, Indonesia, on January 1 until December 31, 2019, were included. Results: In our study, 36 mothers were included. Maternal characteristics included age of 20–35 years in 72.2%, overweight in 50%, referral visits in 69.4%, from out of town (66.7%), bleeding onset at 3rd trimester (97.2%), primigravida (8.3%), nulliparity (13.9%), 69.4% with history of C-section, and 83.3% no hospital readmissions. Maternal outcomes included 100% mothers diagnosed with complete placenta previa and performed C-section. The mothers were mostly (69.4%) diagnosed with placenta accreta spectrum (PAS). There were 36.1% hysterectomy, 33.3% postpartum hemorrhage, 50% blood transfusions, and zero maternal mortality. Neonatal outcomes included prematurity in 80%, low birth weight (LBW) in 51.5%, while 77.1% and 85.7% of newborns had no asphyxia at 1 and 5 minutes, consecutively. Conclusion: All mothers experienced complete placenta previa, and underwent C-section with most of the mothers were diagnosed with PAS. Less than half of them needed hysterectomy intervention because other patients with focal type PAS were planned for conservative surgery. Moreover, they mostly did not have postpartum hemorrhage with half of them needed blood transfusion. There was zero maternal mortality, with most newborns experienced prematurity, LBW but no significant asphyxia.
