Paper waste production in DKI Jakarta according to data from The Jakarta's Environmental Services reaches an average of 40% of total waste production per month for each municipality (kotamadya). On the other hand, Indonesia's necessity of construction development, notably residential home, is increasing constantly along with the amount of Indonesia's population. This condition stimulates innovation of eco-friendly, inexpensive building material with suitable strength. Since 1990's, papercrete, concrete with waste paper as substitution of fine and/ or coarse aggregate, has been studied. Its use for structural materials has evolved and required supporting research for application on larger structural components. In this research, homogeneity aspect of papercrete from domestic waste (office) is investigated along a certain height of vertical beam. To do so, Ultrasonic Pulse Velocity (UPV) propagation measurement on 5 vertical prismatic beam specimens was conducted. By using direct mode transmission, two transducerswere used through 15 cm of width. Rate of propagation can detect the density of concrete at each level since early age of concrete (2 hour after casting). It describes the distribution of material inside. This homogeneity study is beneficial in evaluating papercrete application in real beam structure in the future. [ABSTRACT FROM AUTHOR]

According to Indonesia's National Guidelines on Green Buildings (Kemen PUPR No,21,2021) called Penilaian Kinerja Bangunan Gedung Hijau (BGH), green buildings are mandatory for new and existing buildings. As environmental concerns grow, the Government uses these ratings to control energy consumption. A government initiative aims to increase demand for environmentally friendly buildings. This paper evaluates BGH's green building rating system for project certification in two Indonesian cities, Jakarta and Padang Paser Utara. Jakarta is the capital of Indonesia, the largest and one of the most populous urban city in Indonesia. Moreover, the new Indonesia capital city, Nusantara, will be built in Penajam Paser Utara, East Kalimantan. Using the results of this research, recommendations and suggestions can be given related to the design of green buildings both in Jakarta and Penajam Paser Utara. Evaluations will be conducted on simple residential buildings. The results of these studies indicate that designers and architects may have difficulty incorporating this rating systems into their designs. An evaluation of BGH ratings and sustainability analysis can be performed with building information modeling and a conceptual framework is presented toward the end of this paper. A rating system's success depends heavily on discussion among all stakeholders, including architects, engineers, environmentalists, governments, and communities. Indonesian experts in the building sector should take part in and contribute to this project. [ABSTRACT FROM AUTHOR]

This paper reports an innovative approach in secondary schools in Jakarta that employed ethical dilemma story pedagogy (EDSP) in an integrated Science, Technology, Engineering, Arts, and Mathematics (STEAM) project designed to engage chemistry students in ethical values learning. The study investigated how students explored their own values by attempting to resolve ethical dilemmas about environmental problems in an Indonesia context. Ethical dilemmas comprised everyday socio-scientific issues related to chemistry concepts in the high school curriculum, including pros and cons of using artificial fertilizers and disposal of used cooking oil. This qualitative research was conducted in the chemistry classes of two high school teachers. The research employed multiple data collection methods of semi-structured interviews, reflective journals, and classroom observations. The results illustrate students' successful engagement in chemistry learning, critical thinking skills, chemical literacy, ethical values, awareness of environmental problems, and envisioning of education for sustainability. The results also illustrate (i) students' enhanced awareness of their values and their agency in practicing environmental sustainability and (ii) teachers' realization that they can empower students in education for sustainability through ethical dilemma story pedagogy. The study is significant in revealing that education can play an important role in empowering the young generation in education for sustainability through an ethical values approach to their learning. The paper also addresses challenges faced by the researchers in designing chemistry-based ethical dilemma stories, integrating them into a STEAM project, empowering students, and managing time resources.

Pasar Ikan Modern (PIM) Muara Baru is the first fish market built by the government as an icon of the clean fish market and fulfil sanitation standards in Indonesia. Some goals built this fish market are to increase fish consumption in the Jakarta area and change people's view of the dirty traditional fish market. Building conditions that meet the sanitary standard can prevent disease and guarantee the quality of the fish sold. A clean fish market environment and the application of good sanitation are the main important ways to keep environmental sanitation. This paper aims to identify the environmental sanitation based on SSOP (Standard Sanitation Operating Procedure) in PIM Muara Baru. This research uses the quantitative method. Data was obtained from the observation approach and survey on 30 respondents, all of whomare fish sellers. These results show that PIM Muara Baru has not fulfilled all the procedures in SSOP. From 24 proceduresin SSOP, 13 procedures (54%) were appropriate, and 11 procedures (46%) were inappropriate. [ABSTRACT FROM AUTHOR]

Twitter data provide rich and powerful information to leverage the dynamics of public perception to establish situational awareness and disaster mitigation strategies during critical times. In this paper, we perform topic modeling via Latent Dirichlet Allocation to extract topics from a collection of tweets related to Indonesia flood events in February 2021 with the query: "banjir". The extracted topics are used as one of the features to build a generalized linear count time series model with Negative Binomial distribution. We find seven major topics from the model in which tweets containing a topic about the government's role in handling the situation dominate the conversation. Taking into account a simple intervention analysis, we demonstrate a statistically significant change in the users' behavior before and after the severe Jakarta flood on 20 February 2021. Moreover, a metric evaluation demonstrates that a covariate that describes the turning point of the Jakarta flood event is convenient to build a more accurate count time series model of the tweets.

There are three important elements that need to be harmonized so that the Sustainable Development Goals (SDG's) can be achieved, namely economic growth (economic growth), social inclusion (social inclusion), and environmental protection (environmental protection). The Environmental Performance Index (EPI) 2020 places 180 countries on environmental health and ecosystem vitality, Indonesia ranked 116th. The indicators provide environmental policy targets, environmental performance and provide practical guidance for countries aspiring to move towards the sustainable future. Environmentally sound development is also supported by the government at the policy level in the form of Regulation of the Minister of Public Works and Public Housing of the Republic of Indonesia Number 21 of 2021 concerning the Assessment of Green Buildings. Through this regulation, the government wants to encourage the realization of the implementation of sustainable buildings that are characterized by efficient use of resources and their contribution to reducing greenhouse gas emissions (GHG emissions). The target is to reduce GHG emissions based on DKI Jakarta Governor Regulation No. 131 of 2012, namely from non-provincial buildings of 1.5 million tons of CO2 emissions in 2020 and 5.5 million tons of CO2 emissions in 2030. While the target of the provincial government building itself in 2020 is 49.4 thousand tons of CO2 emissions and in 2030 of 129.5 thousand tons of CO2 emissions. This paper is intended to evaluate the application of Green Retrofitting in Existing Office High-rise Buildings, and proposed alternative ways in order to improve efficiency and effectiveness of Green Retrofit in Existing Office High-rise Buildings development and financing.

To get the OTTV value, you must first calculate the solar radiation value. Solar radiation occurs as a result of the sun's heat being exposed to the surface of the building and then goes inside so that the air temperature inside the building gets hotter. The solar factor is one of the elements of solar radiation which is important in determining the overall thermal transfer value for each outer area of a building. The availability of solar factor data in one place is very important to use for building design purposes. Calculating the solar factor is very difficult, moreover, SNI only contains data for the city of Jakarta. There are several ways to calculate the solar factor, with available SNI tables or by laboratory experiments or direct measurements of sunlight. So to make it easier for the designer, we propose to use the rule of thumb formula. The method used is based on local solar factor data, then a radian angle is made from 0 ° -360 °, which results in an ellipse shape in an equation. This paper concludes that the Rule of thumb formula is very helpful for architects in calculating the SF value and can also complete the table in SNI: 2011, which only contains the SF value for the city of Jakarta, meaning that it only applies in Jakarta, so similar research is needed to get the SF value for other cities in Indonesia.

The COVID-19's rapidly spread in Indonesia is a serious concern for government. Various government policies, such as large-scale social restrictions, which is called as PSBB, and the imposing restrictions on community activities, be called as PPKM, have been applied to slow the spread of COVID-19. These policies were supposed to control people activities in many areas, especially that will invite the crowd happening. In this paper, the control charts be explored to obtain the overview of the daily new COVID-19 cases number, which is considered as a production process. The proportion of positive COVID-19 cases be observed and monitored using P-control chart. The data used is from the specimen COVID-19 test in DKI Jakarta Province, since April 2020 to January 2021. It is obtained that the process of daily new COVID-19 cases number has not been statistically controlled. It is detected some mean shifts of proportion in some point of times. Several findings indicate an upward trend, suggesting that the proportion of positive cases COVID-19 is rising. The public's conduct in Jakarta has served as a model for the government in designing policies to tackle the spread of Covid-19. However, due to the high mobility of Jakarta residents and its lack of consistency in the region, the COVID-19 process still remained out of control. [ABSTRACT FROM AUTHOR]

It is undeniable that the world's climate conditions are experiencing a significant quality decrease where the air around our homes, including Jakarta, are not feasible anymore where there are a lot of dangerous Particulate Matter 2.5 in the air that we breathe daily. Not only the air condition, the high demand for processed petroleum such as gasoline and diesel causes Indonesia to import where in 2018 there are 393,000 barrels per day. Of course, the budget spent to meet the fuel needs is not small, and will not decrease for the next few years, given that Indonesia's petroleum stock has also decreased. Based on these problems, Universitas Indonesia is committed to build an environmentally friendly transportation, called Electric Bus. This Electric Bus has prime mover in the form of a 3 phase induction motor. Author on this paper is doing the research to build an electric motor design used on The Bus, so that the motor can produce performance in accordance to the design specifications that is 100 kW, where three motors will be combined to produce 300 kW of power with 1200 Nm of torque. This research focuses on motor construction, as well as the selection of materials where the material used is from Indonesia so that all components of the motor are originally made in Indonesia, with the best quality and specifications. This design has been successfully made resulting a weight of 298 kg and dimensions of 630 mm x 470 mm. The results of this research are expected to be able to electrify The Yellow Buses at Universitas Indonesia. [ABSTRACT FROM AUTHOR]

The diversity of ethnic groups in Indonesia has been one of the basic factors of the growth of identity in a settlement. Ethnic Chinese has been one of the minority ethnic groups that have become a part of that diversity, after migrating from China and have settled down in Indonesia from the early century (around 1st century B.C. according to Melalatoa [1]), thus making the name Chinatown known as the settlement whereas ethnic Chinese (now Chinese-Indonesian) lived. One of the biggest Chinatown in Indonesia, Glodok area had the identity known as a trading area managed by Chinese-Indonesian from the colonial era until now, and has become a very iconic place in Jakarta for the characteristics as a Chinatown. Glodok that was formed in the colonial era became the place where Chinese identity and Dutch identity interact, and then followed by the interaction with local ethnic groups identities in the following era. Advancement in architecture that was developed in those times became the very uniqueness that makes Glodok distinctive in Jakarta. In that phase, the settlement grows in response to the society and environment growth, especially in times of modernization and new technology. In this case, does the Glodok settlement still maintain its identity in the visualization of the settlement? Or the identity itself has already succumbed through the intense modernization and rapid changing in the environment? This paper aims to identify those changes of the settlement in response to the growing environment, especially in Indonesia whereas the country has a tropical climate that affects the use of building materials in the urban space of Glodok. The methods used to obtain the data needed are literature research on the development of Glodok throughout the history and observation on the growth through the documentation of both the past and the present of the Glodok settlement, and its growth in the aspect of architecture. Therefore, knowing that Glodok does have changes in the terms of settlement, the form and facades of building, the materials used, along with the identity growth. [ABSTRACT FROM AUTHOR]

In recent years, many countries have tried to adapt traffic demand management measures to tackle social problems such as reducing traffic congestion and lowering vehicle emissions. When trying to consider these traffic demand management measures, it is necessary to consider people's travel behavior in detail. It was understood that the implementation of traffic management measures such as road pricing and teleworking has not just affected people's modal choice and route choice, these measures have a high likelihood to change activity patterns of all the people affected either directly or indirectly. The current method of the conventional trip-based traffic demand forecasting (four-step model) focuses only on the change of travel behaviors; however, this method could not represent the change of activity patterns when the traffic demand management measures were implemented. Therefore, it is necessary to apply a much more robust Activity-Based Model (ABM) that could explicitly incorporate the change of activity patterns and estimate the effectiveness of implementing these measures. Thus, this study focuses on evaluating traffic demand management measures based on the change of activity patterns. By applying the ABM, road pricing and teleworking as traffic demand management measures were evaluated using the typical performance indices and activity patterns in the case of the Jakarta metropolitan area, Indonesia. Several key findings were found, population synthesis plays an integral part in ABM calculation. By applying ERP policy in the CBD area, some people shift mode, increase work-related activity patterns, and reduce the generation of secondary activities in order to avoid extra expenses for the toll. Teleworking policy increases other activities such as shopping and leisure, while it reduces work-related activities Hence, it was concluded that the analysis of activity patterns can provide additional information for decision-makers to consider in implementing a policy, by understanding how people change their activity patterns, much more efficient planning can be organized in the future.

The outlet portal of Tunnel No. 8 is located in the hill, and above it is passed by railway and highways with dense traffic. This condition can affect the slope stability when excavation is carried out. Field observations, evaluation of core samples, and laboratory tests were carried out to obtain parameters and properties material used in the analysis numerically. This research modeled the slope at the tunnel outlet with a two-dimensional model on Plaxis software. The model is the slope after excavation, and the traffic load is simulated. The purpose of this research was to determine the stability of the slope after excavation in the presence of rail and road traffic loads and to determine the appropriate slope reinforcement to prevent landslides and erosions. The results show that the outlet portal of Tunnel No. 8 is located in the Quaternary Older Volcanic Product Formation (Qob) with poor (GSI 20-40) to very poor (GSI < 20) rock masses. The safety factor (SF) value without reinforcement is less than required. It can be assumed that the slope is unstable and can trigger landslides on the portal slope and even on the tunnel body. The slope reinforcement system simulated in the Plaxis software uses shotcrete with a thickness of 15 cm. Based on the analysis using shotcrete, it is seen that there is an increase in the value of the safety factor. The safety factor value obtained is > 1.5. Slope conditions with a safety factor value of more than 1.5 indicate that the slope is stable. This research suggests using slope reinforcement for each tunnel portal excavation to prevent landslides and erosions. Slope reinforcement can be applied immediately after excavation, especially in volcanic areas with weak rock masses. [ABSTRACT FROM AUTHOR]

In all aspects of the human life, people have been trying to advantage technology. Pandemic in this 21st century makes a big contribution as well in the use of technology due to minimizing human interactions. Food and beverage business has tried hard to think on how their service could be delivered in this pandemic situation. Restaurants in Indonesia more particularly in Jakarta and surrounding areas started to use online menu retrievable through different ways, but mostly using a Japanese matrix barcode invention known as QR code. However, the practice in restaurants is not as easy as it seemed to be. Consumers seemed disturbed and forced to using the barcode. This research has the objectives to identify the consumer behaviors in restaurants business in Indonesia using online menu through their staff. A qualitative methodology is used to describe the findings with observation and in-depth interview with restaurant staff. It was stated that certain consumers have no problem in using online menu, but human interactions cannot be avoided neither. The characteristics of service industry promote the moment of truth that is still needed for the consumers satisfaction. [ABSTRACT FROM AUTHOR]

The term of "data is the new gold" is commonly used now days. To remain competitive in a tight economy, data processing is one of the core elements allowing businesses or organizations to innovate. Consequently, data scientist is nowadays enhanced the most in-demand profession in the industry around the world. Nevertheless, contradict with the high-demand data science careers, in Indonesia there is a shortage of talent in the field. Therefore, the purpose of this research study is to identify the actual condition of qualifications of data scientist in Indonesia. This research was conducted using qualitative method with 15 respondents consist of data scientist in the Jakarta metropolitan area (Jabodetabek). The findings of this study suggest that there are some inadequate qualifications of data scientist in Indonesia. To further our research, we are currently now in the progress of investigating the gap of data scientist qualifications in Indonesia using quantitative research method. [ABSTRACT FROM AUTHOR]

Covid-19 has spread across the world. To overcome this, the Government of Indonesia implemented a Large-Scale Social Restriction (in Indonesia, it is called PSBB) in several areas, including Jakarta. The research aims to analyze the number of transportation modes and industrial closures on air quality (CO, NO2, SO2, O3, and PM10) during PSBB using descriptive-analytic methods. Our research uses secondary data obtained online from Jakarta's Environmental Services, Transportation Services, and Manpower Services. The analysis used in our study is Mann Whitney and Rank Spearman tests. Overall, the number of transportation modes have more impact than industrial closure. PSBB has impact on reducing CO levels 72,4%, NO2 (78%), and SO2 (0,35%). Coefficient correlation number of modes transportation with CO (R = 0,259; p < 0,001), NO2 (R = 0,384; p < 0,0001), SO2 (R = 0,372; p < 0,0001), industrial closure with SO2 (R = -0,364; p < 0,006). Most motorized vehicles Band industries use fossil fuels. Vehicle and industrial restrictions reduce the use of fossil fuels. Emission reduction will affect air quality. Restriction on the number of industries and vehicles at the time the PSBB significantly reduces exhaust emissions. [ABSTRACT FROM AUTHOR]

Refused-derived fuel (RDF) has been considered as a sustainable alternative for substituting fossil fuels. Fecal sludge is produced daily from sewage treatment plants in large volumes and usually ends in sludge hangars for disposal, as the residue from chemical and biological treatment of human waste. Despite its large volume and low water content, the utilization of fecal sludge as RDF has not been widely practiced in Indonesia. In this study, dried fecal sludge from the dewatering unit of a Sewage Treatment Plant in DKI Jakarta was used as raw material to produce RDF. In this study, pelletizing was carried out as an effort to densify and improve the physical characteristics of dried fecal sludge as RDF raw material. Dried fecal sludge is refined, weighed, added starch for adhesive, then molded into pellets. Pellets are molded using two different pelletizing processes, using screw pelletizer and revolving die pelletizer. The molded pellets were then dried and stored at room temperature with indirect sunlight for 6 hours before being analyzed for their quality parameters. This study analyzed and compared the physical characteristics of pellets produced using two different pelletizing processes for density, hardness, and calorific value parameters that influence the storage, transportation, and quality of the material. The result shows that both pelletizers have improved the quality of raw fecal sludge as refuse-derived fuel. As a result of the pelletizing process, the highest calorific value of the fecal sludge pellets is 3071.028 kcal/kg. The screw pelletizer produced higher calorific value pellets compared to the other, with longer but smaller diameters, larger densities, and smaller hardness. [ABSTRACT FROM AUTHOR]

During the COVID-19 pandemic, the local authority in each city was implementing different approaches to limit the virus spread within the population. Jakarta, as the city with the most reported cases in Indonesia, reinforced the lockdown policy to limit the activities of its people. This regulation has been reported by news outlets as the main factor which improve the traffic condition in Jakarta during this period. The present study proposed a text mining approach to explore this phenomenon in the social media realm, especially Twitter. The tweets used in this study were gathered from the Jakarta police department's official Twitter account, @TMCPoldaMetro. This account regularly reports the traffic condition from several locations across Jakarta. The proposed method extracted the location and its traffic condition reported on the tweets. Then, the weighted scores, from zero to two, were calculated to quantify this traffic condition during the lockdown period (10th of April - 31st of December 2020). These scores are compared to the same period from the two previous years, as well as the previous period within the same year (1st January - 9th of April 2020). Firstly, a series of t-test was conducted to statistically measures the traffic condition differences in general. The result of this study indicates a significant traffic improvement during the lockdown period in overall reported locations. Furthermore, chi-squared tests were also performed to measure traffic improvement in each specific location. Surprisingly, several locations which considered as office district was reported no traffic improvement. [ABSTRACT FROM AUTHOR]

A change order can be defined as a proposed change between the owners and contractors to alter several conditions from early contract documents. In short, a change order can be defined as a modification from an existing contract. According to the Indonesian Presidential Decree Number 16 of the Year of 2018, the contract of change order has been defined. The purpose of this research is to identify the factors that cause a change order in a long segment road preservation works in Jakarta Region, Indonesia, based on the results of the previous analysis by the author. It also aims to identify, analyze, and determine the best method to lessen the negative impact of change order through risk management.

The increased usage of plastic for personal protective equipment (PPE), single-use plastic grocery bags, and food packaging during the COVID-19 pandemic raised concerns on microplastic pollution. This study aimed to investigate the shape, abundance, and type of microplastics in the seawater of Jakarta Bay where is most likely to be polluted by anthropogenic activities as well as being the endpoint of 13 river systems. The seawater from Tanjung Priok, Ancol Beach, and Sunda Kelapa Port, were collected and extracted using the density separation method. The microplastics were counted and categorized under a microscope and polymer of microplastics were identified using FTIR. The differences in microplastic abundance in three different stations were determined using one-way ANOVA. The results show that the Sunda Kelapa Port (2577.78 214.30 particle/m3) had the highest abundance of microplastic, which was significantly different (p<0.05) from Tanjung Priok (2022.22 203.67 particle/m3) and Ancol Beach (1822.22 101.83 particle/m3). The microplastic shapes in the Sunda Kelapa Port were dominated by fragments (36.2%), meanwhile, Tanjung Priok and Ancol Beach were dominated by fibers, comprising 37.34% and 35.44%, respectively. The results of the FTIR spectroscopy show that the most common types of microplastic polymers are Polypropylene, Polyethylene, Polystyrene, and Polyamide. [ABSTRACT FROM AUTHOR]

Indonesian government has officially issued a policy of moving the State Capital from the Province of the Special Capital Region of Jakarta to Kalimantan Island. The policy has not yet determined the province that is formed for the capital city on the island of Kalimantan. The State Capital transfer policy is planned to be carried out starting in 2020. However, due to Covid-19, it seems that the transfer of State Capital cannot be carried out. Looking at the data on the website of the House of Representatives of the Republic of Indonesia (DPR RI), it appears that there is already a list of Draft Laws on State Capital that are included in the National Legislation Program (Prolegnas). This means that the State Capital transfer policy is really serious about being implemented. Based on some information, the State Capital plan will be based on a smart city. Of course, this is interesting considering that the world is currently leading to the development of a smart city-based region. But the question is whether the State Capital transfer policy is correct from a legal aspect, considering that the State Capital Law has not yet been formed? Then does the smart city-based State Capital transfer policy have an impact on ecology and social welfare? This article analyzes and answers that question. This article analyzes in depth related to the legal aspects of the State Capital transfer policy. This article also analyzes the impact of the State Capital transfer policy. The impacts to be analyzed in this article are ecological impacts and social welfare. The conclusions in this article are specific answers to the questions posed in this article.

At the beginning of the year 2021, government of Indonesia has started a COVID-19 vaccination program targeting 70 percent of people vaccinated by the end of 2021. This target is basically based on the assumption that with 70 percent vaccinated people, herd immunity at the national level is achieved. The success of the program very much depends on several factors, such as the availability of vaccines, schedule of incoming pre-ordered vaccines, implementation schedules and readiness of vaccination officers, and targeted people. In this study, we analyze and simulate the immunity level of the vaccination program in Jakarta based on the reported government plan and target as well as the characteristic of the existing vaccines. The short-term dynamics of vaccination scenarios are investigated by the discrete SIRV model. Furthermore, the second-year vaccination scenarios and long-term analysis of herd immunity are investigated by continued SIRV model. [ABSTRACT FROM AUTHOR]

Indonesia, as one of the largest population country, faces a problem with the availability of clean water. The increasing of the population every year results in the increasing of clean water needed. It also causes the increase of wastewater, especially domestic wastewater. As one of domestic wastewater, household wastewater in Indonesia, especially DKI Jakarta, is one of the main cause of river pollution. Household wastewater disposed directly into the river. Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) are some substances contained in it. Therefore, it is necessary to manage the wastewater before the disposal. Filtration processing is one of the wastewater treatment method used to reduce the pollutant level in the water. The materials are able to reduce the concentration of COD and TSS. This study aims to verify if filtration can be used as a method to reduce household wastewater by the study of literature. Besides, the researcher also used other materials to process sample from household wastewater. Filtration can be used as a simple method, so that it can be applied by the community, especially those not covered by wastewater treatment plant (WWTP). [ABSTRACT FROM AUTHOR]

Indonesia still has a high maternal mortality rate. There were 305 mothers mortality of 100.000 live births in 2015. The rate was far below MDG’s target. One of the strategies to reduce the rate is to ensure mothers could gain access to excellent health services and reliable health information about pregnancy, delivery, and reproductive health. Digital communication and smartphones could be utilized to provide access to health information and digital publication through an application are one of the options that modern-day women could use. Therefore, we developed smartphone based reproductive health application named Jakarta Reproduksi Sehat (JAKPROS) which provide three sections, including prenatal care, cervical cancer prevention, and reproductive health. This application contains educational materials, question and answer forums, a hotline with health services center, and important information about reproductive health. In short, this application has everything that is important for pregnant mothers and women in general. We acknowledge that many diseases main risk factor was lack of education, therefore increasing the mothers and women knowledge could decrease high – risk pregnancy, and for long-term purpose could decrease the maternal mortality rate. Obstetricians also could monitor their patients through this application with JAKPROS record health information, from the patient weight, blood pressure, estimated date of delivery, fetal heart rate, fundal height, and contractions. So that obstetricians could manage high-risk pregnancy and immediately intervene when needed. We previewed this application into several sub-district general hospitals in Jakarta testing its features, implementing the app into daily clinical practice. This study showed there are 205 active users in JAKPROS, including 65 obstetricians and gynecologist and 140 patients only in Jakarta, this application downloaded more than 200 times from the Play Store.
