Qualitative study of obstacle to community empowerment in waste management: Community perspective in DKI Jakarta

Even though waste has become a big problem in Jakarta, the efforts to overcome it are still running poorly in reality. Many obstacles make community empowerment in managing waste difficult. Population numbers and increased economic capacity and community production, for example. Besides the problem of urbanization in general, the community’s role in learning and taking the initiative in empowering themselves to avoid the problem of waste is still low. This study uses a qualitative method with theoretical and recent studies review, policy review, and critical analysis of the theory. Barriers to the community’s internal problems and the lack of seriousness of attitude from the government can be seen as a phenomenon that shows obstacles also exist in socializing the values of waste management properly.

Passive design implementation as sustainable development approach on vertical housing case study: Sentra Timur Residence

Vertical housing development is a solution to solve the housing needs problem in Jakarta, which already had a land limitation issue. However, the development also contributes to environmental degradation. Building uses materials and energy in the development process, and when it operates. Most of energy use in Heating, Ventilating, and Air Conditioning (HVAC) to create physical comfort for user. Passive design strategies applied to maintain comfortable temperature in building such as building orientation, shading, and ventilation, so energy usage could be reduced. The purpose of this research was to analyse the implementation of passive design in vertical housing, as an approach to achieve sustainable building. Observation carried on Sentra Timur Residence, one of vertical housing in East Jakarta. This research used building data to create mass modelling to help analyse the passive design implementation. The results show that some passive design strategies are applied such as building orientation, shading, and ventilation, mainly in the housing unit. These strategies help to maintain thermal comfort inside the housing unit, so the users can feel comfort without using an air conditioner. It reduces energy usage in the building so negative impact on environment could be minimized.

Dilema Sosial Pengguna Transportasi Jakarta: Survai Penilaian dan Niat Menggunakan Transportasi Publik di Jakarta

The traffic problem in Jakarta can be seen as a social dilemma problem. The commuter here face the dilemma to decide to commute by private or public transportation. This decision situation reveals the conflict between immediate self interest and longterm collective interest. The goal of this reseach is twofold. First, the research elaborrate the differences in the level of interest of among the commuter in the transportation modes. Second, the research analyse the influence of social dilemma awareness of the commuter to prioritize the common interest of the commuter. The first reseach question is answered by employing descriptive analysis and the second one is analyzed by inferential analysis. The results of this research reveals some important points. First, the commuter think that the congestion is the most traffic problem in Jakarta. Second, private transportation is preferred transportation mode than public transportation. Third, the commuter intention to prioritize public transportation is influenced by three factors, i.e. flexibility, low fare, speed (short duration).

Persepsi Masyarakat Tentang Kemacetan Lalu Lintas di Jakarta

The aim of this research is to identify public opinion about the suitable modern public transportation modes in Jakarta. Transportation is inseparable from traffic jam which also affects the residential areas. Traffic jam is a stagnant situation caused by the number of vehicles exceeding the road’s capacity. Traffic congestion becomes daily problem in Jakarta and other cities in Indonesia. This research used qualitative method. The result of this research shows that traffic congestion in Jakarta was caused by large number of private vehicles. Due to that condition, the suitable public transportation modes are, Monorail, TransJakarta bus, Tram, MRT, and LRT. 48% of Jakarta citizens chose monorail as the most suitable transportation while 38% of them preferred Transjakarta bus, and 14% of people asked for tram. The expectation of the realization of modern transportation mode, in this case monorail, is to decrease the number of private vehicles. Therefore, the traffic congestion in Jakarta are able to be reduced.

The tendency of public’s attitudes to evaluate urban congestion charging policy in Asian megacity perspective: Case a study in Jakarta, Indonesia

Urban congestion charging (CC) is regarded as a potentially powerful instrument aimed at changing road users’ travel behavior and achieving efficient infrastructure use. Yet, at the same time, implementing this policy is not easy. There are thoughtful barriers to the pursuit of the CC implementation. The public is skeptical about such a policy, so public rejection arises mainly among car users. The acceptability of a CC reflects public’s attitudes towards the scheme and public support is regarded as a prerequisite. Understanding this is crucial to any investigation of what might improve public acceptability. Given an absence of studies from the perspective of Asian megacities, a comprehensive stated choice (SC) survey is conducted in Jakarta, where CC scheme has been introduced and remain under consideration as a way to mitigate acute traffic congestion. A multiple-indicators multiple-causes (MIMIC) approach is applied to investigate causal paths among psychological determinants that representing public’s attitudes and their strength from psychological perspectives. Statistical findings depict that a CC acceptance can be influenced and explained by an individual’s psychological motivations such as perceived effectiveness and awareness of the proposed scheme. Psychological motivations including “awareness of the city’s environment” and “awareness of the problem of cars in society” appear to be the most important direct determinants leading to recognition of the effects of a CC scheme and they are indirect determinants of policy acceptance. Furthermore, the car-dependent society is seen as part of the problem in Jakarta, and people who are dependent on the car are more likely to understand that an effective policy is needed to address this problem. We found that people had explicitly mentioned “awareness of city’s environment” and “awareness of problem car in society” as the two most popular reasons for supporting the CC. Additionally, path analysis result on the effect of specific measure “trust in government policy” on the correct and acceptable policy has revealed a positive determinant. These indicate the important role of current government performance for achieving acceptability for CC proposal. Public marketing campaigns to promote CC are strongly recommended to focus on providing the public with credible and specific information related to perceived effectiveness and awareness (less congestion and a better environment).

Study on Hydraulic Flow in Stratified Pipe Performed by Numerical Simulation

An idea of introducing an underground floodway inspired by Storm-water Management and Road Tunnel (SMART) in Malaysia is considered attractive to minimize land utilization regarding to the flood problem in Jakarta. This research was aimed to know the flow behavior of this modified tunnel due to sudden transitions, pressure losses and loss coefficients using numerical modeling. The simulation was conducted in the three-dimensional model using FLUENT Software which was divided into three models, i.e., contraction, enlargement, and straight pipe model. The simulation model was followed the geometrical design of SMART which the area ratio between smaller and larger pipe, A1/A2 varied, namely 0.20, 0.50, and 0.80. Standard k-ε and equilibrium wall function were used in straight pipe model, while contraction and enlargement model used k-ε modified and non-equilibrium wall function. The effect of different Reynolds number was also studied in this research. The result of the simulation showed that hydraulic parameters and area ratio of sudden transitions pipe give significant effect towards losses along the pipe. FLUENT simulation result gave good agreement with Darcy-Weisbach formula. The results indicate that loss coefficient decreases with the increase in pipe area ratio. The increase in pressure head loss was incurred by severe separated regions in the vicinity of pipe transition which was proved by typical flow pattern. Variation of Reynolds number also showed a different area of separation flow, yet the flow pattern was somewhat similar.

Reverse logistic location problem for electrical and electronics equipment waste treatment facility

Reverse logistics plays a significant role in reducing electrical and electronics equipment waste (e-waste) problem by returning some valuable or hazardous parts back to the distributor or producers. This paper implemented reverse logistics facility’s location problem to find the optimum location of e-waste treatment facilities. E-waste treatment facility location was determined in two phase. First, facility location model is developed to find the optimum location for e-waste treatment facility from the e-waste collecting points using K-means clustering and centre of gravity algorithm. Once the treatment facility location is decided, e-waste collection vehicle routing model is developed using saving matrix algorithm to minimize collecting distance. This paper was developed in three scenarios, based on e-waste collection problem in Jakarta. It is found that multi e-waste treatment facilities, gave the shortest collection distance compared to single and restricted area facility scenarios.

Analysis of land use changes to the criticality level of the catchment area in eight watersheds that flow into Jakarta Bay, Indonesia

Environmental problems in Jakarta, especially flooding problem, is strongly influenced by the condition of eight watersheds that flow into Jakarta Bay, namely Bekasi, Cisadane, Angke Pesanggrahan, Ciliwung, Krukut, Cakung, Buaran and Sunter. The center-periphery relationship between Jakarta and surrounding areas triggered significant land use changes in the watershed, especially in the upstream area. This study aims to analyze land use changes in eight watersheds that flow into Jakarta Bay in 2000, 2009 and 2017 as well as their effect on the distribution of the criticality level of the catchment area, using Geographic Information System (GIS) refers to Planning Procedures for Forest and Land Rehabilitation Engineering Watershed. The criticality map of the catchment area was created by overlay and scoring slope infiltration map, soil infiltration map and rainfall infiltration map. The results showed that there was a significant increase in built-up area of 14,33% in 2000-2009 and 10,42% in 2009-2017. In contrast, the area of dry land farming decreased significantly by 12,99% in 2000-2009 and 5.96% in 2009-2017. Based on the criticality analysis of the catchment area, land use changes in study area, mainly due to urban growth, has a significant effect on the criticality level of the catchment area.

Estimation of river flood damages in Jakarta, Indonesia

Flooding is a serious problem in Jakarta, and detailed estimation of flood damage is necessary to design optimal flood management strategies. This study aims to estimate flood damage in a densely populated area in Jakarta by means of a survey, to develop the relationship between flood characteristics and flood damage, and to compare the damage estimates from the survey with the damage estimates obtained by a flood damage model for Jakarta, i.e. the damage scanner model. We collected data on economic losses of the January 2013 flood in a survey of flood-affected households and business units in Pesanggrahan River. The actual flood damage in the survey area is US$ 0.5 million for the residential sector and US$ 0.7 million for the business sector. The flood damage for a similar event in the same area based on the damage scanner model is estimated to be US$ 1.3 million for the residential sector and US$ 9.2 million for the business sector. The flood damage estimates obtained by the survey approach are lower compared to the damage scanner approach due to different ways in obtaining flood damage data and in defining the maximum flood damage per object, the different spatial levels of analysis, and uncertainties in constructing the flood damage curves that were applied in the damage scanner model.

Creating People's Awareness and Pushing Active Contribution. Case: Wider Public Engagement on Flood and Land Use Problems in Jakarta and Surroundings

On late January 2014, the public response through internet to the work of Jakarta local government has generated 113,695 negative and 14,857 positive sentiments. This phenomenon has showed the potential of the internet and the fact that our society is connected. It also showed that everyone could participate in city planning discussions, which in this case were about flood and land use. This paper exposes an exploration of this potentials through (a) critical investigations on internet user about how people's awareness and engagement are created through internet, (b) observing websites that focus on land use and ways of solving flood in Jakarta and surroundings, (c) developing a website www.dagedubrag.org, that is indeed created to generate people's awareness and make them actively contribute and collaborate in city planning for wider public engagements.

Hybrid self-adaptive-velocity particle swarm optimisation-Cooper heuristic for the facility location allocation problem in Jakarta

By solving the facility location problem, one can locate facilities under constraints such that customers are served efficiently. This is a case study of Logistic Company X, which will build new depots in Jakarta, Indonesia. The depots must be located in an industrial and warehousing area. A proposed continuous uncapacitated location allocation model is applied to solve the problem, which has many bounded polygonal zones as constraints. The objective of this study is to determine the number of depots that should be opened in the defined areas, and the number of customers that each depot can serve, such that the total cost, including transportation cost and setup cost, are minimised. The proposed self-adaptive-velocity particle swarm optimisation (SAVPSO) algorithm with the Cooper heuristic algorithm (hybrid SAVPSO) is used to solve the problem. Numerical results indicate that the proposed algorithm is effective and gives better solutions than a generic algorithm and the non-hybrid SAVPSO under various test conditions. The hypothesis test also demonstrates that the performance of the hybrid SAVPSO is better than that of the SAVPSO. Finally, sensitivity analysis is also performed to identify the problem's sensitive variables to support decision-making in this warehouse location problem.

Mathematical Modelling of Injection Wells for Flooding Prevention in Jakarta

Flooding problems in Jakarta cannot be handled comprehensively untill today. Various efforts in the short-term programs and long-term programs have been conducted but the results have not been satisfactory so that the flooding problems still threaten every year and the intensity of floods is likely to increase. The objective of this study is to find alternative flood controls, namely, the injection wells, which is cost efficient and resolves the problems effectively. Injection well applications, as new methods, for flood control in Jakarta seem to be a very attractive alternative in respect to both technical, social impact, as well as the financial aspects. In addition to flood control, at the same time, injection wells may prevent seawater intrusion.Mathematical models were developed to represent the magnitudes of flooding problems, to predict the number of injection wells required, implementation schedule, as well as to estimate the investment cost for the application of injection wells. This modelling can be used to simulate the injection wells development plan with reference to the data that has been proven in successful experience, or based on the pilot scale project. Injection wells application for flood control in Jakarta is technically and financially very feasible, not only to cope with flood problems but also to control the sea water intrusion.

The Trend of Dengue Hemorrhagic Fever Cases in Central Jakarta 2008-2010

Dengue hemorrhagic fever (DHF) constitutes a significant public health problem in Jakarta, thus it is crucial to plan preventive measure before an outbreak occurs.The aim of the study was to find the trend of DHF cases in Central Jakarta. Subjects were diagnosed for DHF in Central Jakarta from 2008 to 2010, and were documented by Sudinkes (District Health Office) of Central Jakarta. Investigation was conducted on the trend of DHF cases using secondary data, while adjusting for several criteria such as age, gender and case fatality rate (CFR).The results showed that peak incidence of DHF infections was detected in May 2008, and in March 2009 and 2010. There was no difference observed between male and female (p<0.19), whereas adult personnels were more susceptible to suffer from DHF compared to children (p<0.001). CFR appeared to be under the standard (<1%).CFR of DHF in Jakarta has to be maintained as of <1%. This can be done by conducting several efforts on decreasing of DHF cases. To conclude, all societies living in the area of Central Jakarta should be aware of DHF and the awareness has to be raised particularly from

Gagalkah Transjakarta? Kajian Kualitas Layanan Pada Sistem Angkutan Cepat Massal TransJakarta

The research aimed to study the busway users’ understanding, attitude, and behavior toward the quality of TransJakarta service, in order to provide alternative solution over the complexity of massive transportation problems in DKI Jakarta, as the capital city of Indonesia. In addition, the research presented some inputs to overcome the transportation problems in Jakarta that can be used as points of evaluation for other cities in Indonesia which have prepared or are preparing to make use of bus rapid transit system. The research was focused on the quality of TransJakarta service, and identifed the necessary atributes to produce an optimum public service quality–as a part of social engineering study on massive transport system. The analysis used Service Quality (SERVQUAL) dan Importance-Performance Analysis (IPA) concepts, done through surveys on 450 respondents on eight busway corridors. The result showed that the users of TransJakarta value most the dimension of empathy and quite the reverse value worst the dimension of tangible. The data showed that empathy is the dimension in which service quality “is considered” most likely improved. While other dimensions, especially the dimensions of tangible, responsiveness and assurance ‘are considered’ already given, since the TransJakarta users regard them as being outside the management limit of Public Service Board of TransJakarta.

PRA PERANCANGAN WATERBUS DENGAN PENGGERAK MOTOR LISTRIK BERTENAGA SURYA DI BANJIR KANAL BARAT JAKARTA

The problems of traffic jams and the issues of energy problems in Jakarta have been generated an innovation and an alternative solution in public transportation development which can reducing these problems that using the renewable energy Referring to the condition and these problems, the concept must be done within pre-design of waterbus which equipped with a solar panel system engine. The using of solar system as an energy resource on the pre design of the ship must be suitable on the water condition, the selection of the solar panel, 3 dimensional with sail routes and analysis calculation when the ship sailing The research is aimed to produce main dimensional of the ship which LOA = 12,00 m, LWL = 11,47 m, Bm = 4,34 m. This ship is using two outboard electrical motors which producing 2 KW of power, 15,954 watt of battery and 52,12 m2 of solar panel with monocrystaline type with 5,520 watt of power which defined from speed of the ship at 5,25 knot with 0,4 KN resistance

The causal relationship of the service quality of the TransJakarta Busway

The implementation of the TransJakarta Busway in 2004 is viewed as one of the solutions to provide higher-quality public transportation service to solve the transportation problem in Jakarta. An improvement in service quality requires research that rigorously explores the experiences and perceptions of users of this mode of transportation. This article aims to provide an explanation regarding the causal relationship of the service quality of the TransJakarta Busway. The analysis employs two data sets that were collected from questionnaires: a data set pertaining to the first corridor and a data set pertaining to all of the corridors (seven corridors). Structural equation modelling is employed to show and test the causal relationship of the constructs of loyalty and service quality based on image and fact. The study shows differences in the factor loading between the two models; therefore, an analysis of the service quality of the busway system necessitates an evaluation of each aspect from all of the corridors to obtain a representative result rather than relying on information pertaining to only the oldest single corridor. The results of the causal relationship analysis suggest that the operator should devote attention to each attribute of service quality and the unique situation of each corridor. Based on the images and experiences of the users, the operator should provide a standard level of quality to all corridors to reduce the gap between image and fact.

Investigating Commute Mode and Route Choice Variability in Jakarta using multi-day GPS Data

Traffic congestion has become a part of commuters’ life in Jakarta for several years. Even though 3-in-1 traffic regulation has been implemented since 1992 in order to reduce the number of car driver travelling in busy corridors during morning and evening peak hours, and Bus Rapid Transit (BRT) has been operated since 2004, which is aimed to attract car drivers to use public transport, the traffic congestion problem in Jakarta has not been solved. The condition is even predicted to worse if the transport facilities in Jakarta are not improved. In order to find effective measures for reducing car use and improving public transport attractiveness in Jakarta, better understanding of commute mode and route choice behavior would be advantageous. This paper reports the first results of data analysis regarding dynamic behavior of commuters’ mode and route choice in Jakarta. The data were collected using GPS devices including questionnaire sheets during a one-week period. 93 commuters participated in the survey. Even though commute trips are routine trips and therefore often assumed to be static, the results show the presence of dynamic behavior in choosing both modes and routes for commuting. The dynamic behavior is as a way to avoid traffic congested roads and 3-in-1 corridors, and to maintain trip-chaining activities/stops. Car drivers and motorcyclists change frequently their routes, especially during work-to-home trips. Motorcyclists were more dynamic in choosing their routes than car drivers. A unique pattern of mode and route choice behavior was found which can be used for developing mode and route choice model in Jakarta.

Transportation in big cities has phenomenal progressrecenly, with growths in automotive vehicles number over the infrastructure and roads length. Jakarta as the bigest cityand the capital of Indonesia has stronger economics, wider areas, more automotive vehicles number, and its populations. Data in the survey, literatures, and analysis over three years in Jakarta, has shown fantastic changes of automotive vehicles number growth composition. Two wheels automotive vehicles growth and number are in the top rank from other categories. Survey of Jakarta has shown economics growth that has increased prosperity of some population group, caused to automotive ownership taxes increase. In the contrary it has also negative effects in inefficiency and national social cost caused from traffic problem. It is suggested that options possibility to overcome from traffic or transportation problem in Jakarta, especially related to traffic management or automotive vehicle ownership management.

UNIT-UNIT PEMROSES PENGOLAHAN LIMBAH CAIR DOMESTIK SKALA RUMAH TANGGA

In the last ten years water pollution problem in Jakarta has been becoming more serious. The highly increasing population causes the rising amount of domestic wastewater. Rivers in Jakarta have already been polluted by various wastewaters, such as from industries, domestic and many institutionals (offices, hospitals, markets/shop areas, etc.). It has been well known that the domestic wastewater contributes 70% in causing the river pollution, especially in Jakarta. Therefore it is very important to apply the proper domestic wastewater treatment system which is able to reduce thecontaminants until an environmentally required standard. Some types of domestic wastewater treatment have already been used, but the results do not fulfil the environmental required standard. At least a unit of domestic wastewater treatment should have a control tank as the beginning filter, anaerobic part, aerobic part and a sedimentation tank as the final part of the whole system. An advanced technology using a biofilter media has been proposed and based on the experiment, the result has proven that it can reduce BOD from more than 1,000 ppm to less than 30 ppm. The retention time is about 3 days. The conclusion shows that this new wastewatertreatment system is properly suitable alternative to be applied in domestic area, especially in a densely populated region. By applying the system we can also cope with the water pollution problem caused by domestic wastewater.
