Marine Debris Collection Model with Intermediate Transition Station (ITS) Systems Planning in Jakarta

Marine debris in Jakarta is a complex problem because the amount is too large every day. Addressing this critical gap, this study proposes a model for efficient waste transportation through the development of an Intermediate Transition Station (ITS) system. This system not only facilitates the effective movement of waste but also incorporates a recovery process to reduce the volume of debris before it reaches the landfill. The ITS serves as a pivotal node in the waste management network, ensuring the continuity of waste flow from accumulation points to processing facilities. With the ITS, the total marine debris managed amounts to 39.96 tons/day, of which 9.33 tons/day is recovered, leaving a significantly reduced residue of 25.63 tons/day or 1.134 m3/day for landfill disposal. Implementing the Haul Container System (HCS) within this framework, the study demonstrates that waste transportation from the ITS to Jakarta's Bantar Gebang Integrated Waste Processing Site can be streamlined to just 3 trips/day. By providing a structured and strategic approach to marine debris transportation, the ITS model aims to prevent the re-pollution of Jakarta's water bodies and significantly reduce the carbon footprint by 67.2% from current conditions, thereby offering a sustainable solution to this pressing urban environmental challenge.

Fostering Community Empowerment: A Human-Centered Approach to Designing Clean Water Solutions in a Jakarta Slum

This article presents a case study of the application of human-centered design (HCD) as a codesign approach to address complex problems in slum communities in Jakarta, Indonesia. Through a review of relevant literature, we examine how the HCD methodology embraces a participatory framework but retains a certain degree of control not found in pure participatory approaches. We explain why HCD was selected for this study and describe the methods used, including sort cards, solution cards, in-depth interviews, focus group discussions, and product usability interviews. These methods were employed to generate a solution that addressed the issue of sourcing clean water in Jakarta’s slums, which was then prototyped, tested, and implemented. The study contributes to the development of a cohesive and applicable methodology by integrating codesign and HCD in designing solutions for people at the Base of the Pyramid.

Analysis of Time Series Water Level Data Prediction Using Deep Learning Method at the Water Gate of DKI Jakarta Water Resources Office

Indonesia has 2 seasons, namely the dry season and the rainy season. During the rainy season, many points in the DKI Jakarta area experience flooding or inundation. The reason why Jakarta often experiences flooding is caused by several factors, including local rain floods, shipment floods and tidal floods. The DKI Jakarta Water Resources Agency currently does not have a system that can predict future water levels by referring to past and present water level data. Through this background, the author tries to conduct research in one of the floodgates in the northern area of DKI Jakarta in predicting water levels using deep learning methods , namely Recurrent Neural Network (RNN) and Long Short Term Memory (LSTM). The purpose of this research is to analyze the best deep learning models and predict water level time series data. From the results of the analysis carried out, the best deep learning model is Long Short Term Memory (LSTM) using several tests such as n-input, split data with a composition of 90.33% train data and 9.67% test data , as well as testing of different parameters including epoch, batch size, learning rate, dropout , so the results obtained are the lowest error values with RMSE (17.65), MAPE (0.29), MAE (3.37) and the time needed in the process (runtime) is 39 minutes

The Assessment of Citarum River Water Quality in Majalaya District, Bandung Regency

Citarum River is one of the biggest rivers in Java Island and the primary source of Jakarta's water supply. Named the dirtiest river globally in 2013, the Indonesian government is committed to improving the Citarum River's water quality by 2025. However, the Majalaya District, the center of the textile industry area in the upstream part of the Citarum River, is indicated to have significantly contributed to the river pollution. Hence, it is essential to conduct a study to evaluate the water quality in the Citarum River, especially in the Majalaya District. The results showed a considerable decrease in water quality from upstream to downstream of the Citarum River in 2013-2021. Concurrently, it was also found that the factory effluent far exceeded the permissible limit.

Assesing Jakarta Water Provision Planning

This study aims to understand Jakarta’s water supply structure and is a part of research on Jakarta’s water supply provision planning. Our analysis on a 14-year water balance estimation, statistic and archival analysis, as well as policy and institutional analysis identify that the metropolitan dependence on groundwater is immense; about 65% of water needs are supplied by groundwater and this has caused critical land subsidence in many areas including in the business center. Several projects to shift from groundwater to surface water have been carried out, and this study concluded that when these projects were to be completed in 2030, the number of people served by centralized piped water will be increased and the dependence on groundwater could be reduced. But at the same time, the reliance on supply from areas far from the city for centralized piped water system will also increase. To increase Jakarta water security, water supply provision planning should focus on processing local water.

Plastic pollution in the surface water in Jakarta, Indonesia

Plastic pollution in the ocean primarily originates from the land-derived mismanaged plastic waste that is transported by rivers. This study aimed to estimate the plastic litter generation in the surface water in Jakarta and Indonesia. A field survey was conducted at six riverine sampling points (upstream to downstream) and three holding facilities of the litter in Jakarta during the rainy season. The Jakarta Open Data database was used to estimate the tonnage of plastic litter. By mass, plastic comprised approximately 74 % of the anthropogenic litter in rivers and 87 % in holding facilities. The riverine plastic proportion slightly increased downstream. Approximately 9.9 g/person/day of plastic litter was discharged into Jakarta's surface water during rainy season and recovered by floating booms. To reduce plastic pollution and its severe impacts on aquatic ecosystems and human health, further field investigation is necessary to design an effective clean-up system and litter-prevention strategy.

Jakarta water supply provision strategy based on supply and demand analysis

Abstract Robust water service delivery systems require an understanding of resource dynamics as a basis for planning sustainable solutions for Jakarta, the capital with challenging water service provision performance. A significant gap needed to be closed with a service coverage of 64.06% and non-revenue for water at 45.06%. However, there is no detailed information on Jakarta's water supply and demand, which is essential to understand the resources situation. This study estimates Jakarta's total water supply and demand for 5 years. Furthermore, we analyze the natural and socio-economic factors shaping the current supply and demand using thematic analysis based on the DPSIR (Driver, Pressure, Status, Impact, and Response) framework. This paper contributes to two building blocks in the system strengthening approach to water and sanitation, i.e., (1) the sector policy strategy and (2) planning, monitoring, and review. Key drivers, pressures, status, impacts, and responses were critical to informing the system-wide understanding of the problem and suggesting evidence-informed explanations for a better water supply provision strategy in Jakarta.

ANALISA KERUSAKAN PISTON MESIN DIESEL POMPA BANJIR DAN OPTIMASI SISTEM MANAJEMEN PEMELIHARAAN

ABSTRACT
 To overcome the floods in Jakarta, DKI Jakarta's Water Resources Service alerted 144 (one hundred forty-four) pump houses that crossed the Ciliwung River. In addition to alerting the pump houses, DKI Jakarta also prepared 133 (one hundred thirty-three) portable (mobile) pumps spread over 5 (five) administrative cities. From the information obtained it is known that in January 2018 there was damage to the 1103 Series diesel engine piston, 50 kVA Generator drive, 36 kW operating in the Jakarta flood pump. Identified factors causing failure are preceded by a high-temperature indication on the cylinder wall which causes the piston to be stuck due to a lack of cylinder block lubrication. This study will identify the factors causing damage to the diesel engine flood pump in West Jakarta, analyze the failure of the piston engine diesel flood pump, determine precautionary measures, and determines maintenance techniques to avoid the same damage to the flood pump diesel engine piston, & analyzes the maintenance management system applied to the diesel engine. This study uses qualitative research methodology with the process of testing stages: macroscopic, metallographic, chemical composition analysis, hardness, SEM (Scanning Electron Macroscopy) which is equipped with EDXS (Energy Dispersive X-ray Spectroscopy) analysis, Schedule Oil Sampling. From the results of the discussion, it was found that the factors causing the piston diesel engine failure to the flood pump were very influential, by testing: 1) metallography obtained by the piston microstructure in the form of aluminum dendrite which indicated that the piston had local melting which resulted in local overheating; 2). viscosity (viscosity) of used oil is obtained: TBN (Total Base Number) on oil is a little low, oxidation is slightly above normal because of incomplete combustion, and there is an increase (difference) in the elements of Fe and Cu in used oil that is 9 ppm and 3 ppm, where if the Fe> content will cause damage to the Cylinder Block Liner & piston & if Cu> will cause failure to the bearing. From the results of this research, it is necessary to optimize the maintenance management system, namely: 1) implementing a Standard Operation Procedure for diesel engines (Inspection: fuel, radiator water, ACCU water, engine oil, R-S-T-N cable, ACCU cable, etc.); 2). perform predictive maintenance of diesel engine components (System maintenance: fuel flow, lubrication, air intake, and exhaust, cooling, starting system); 3). do preposterous maintenance (inspection: daily, 250, 500, 1000, 2000, 3000, 4000, 6000, 8000 and 12000 hours).
 Keywords: Failure, Pumps, Diesel Engines, Piston, Viscosity, Maintenance Management. Keywords: Centrifugal casting, tube reformer HP modified, creep test, Larson Miller parameter, remaining life assessment.

The Right to Water in Jakarta: Limitation in a Sinking City

Unsustainable groundwater extraction in Jakarta has resulted in the subsidence of its land. Said effect had prompted the Regional Government to limit groundwater extraction. Consequently, the limitation threatens Jakarta residents’ minimum core enjoyment of the Human Right to Water (HRtW). People who live in coastal areas are the most affected. Northern Jakarta have considered the limitation as a burden that force them to spend more on necessities. Since there are no safeguards nor alternatives and that the limitation is from the Regional Government is disproportionate, this study argues that there is a violation of Jakarta residents’ Human Right to Water since their access towards water has been impeded, especially in areas without piped water. The Human Right to Water is a fundamental right, a foundation of the enjoyment of other rights. Like other human rights, it can be limited if the alternatives have already been installed. This study argues that, in the case of Jakarta, the safeguards that are supposed to be put into place is the progressive realization of Human Right to Water. It is the installation of a holistic piped water network. Indonesia has an obligation to provide piped water as a safeguard to its limitations otherwise international human rights law will be violated.

Demand and Supply Analysis as a Basis for Jakarta Water Provision Planning

Water provision is a necessity to reduce the risk of coronavirus contamination. Delivering water and sanitation services is now more critical than ever; the hygiene requirements increased water need. It is expected to grow even after the pandemic as a healthier habit that will become a routine for most of the population. In addition, economic activity is predicted to expand once the pandemic is under control. To safeguard sustainable water provision, it is critical for Jakarta to have comprehensive planning based on careful calculation of demand and supply. This is especially valid as climate change adds the pressures to water availability that have long been experienced by the capital, such as pollution, high reliance on groundwater, huge water supply from outside the region, lack of infrastructure, land subsidence, floods, and land-use change. This study aims to estimate the demand and supply for Jakarta’s water comprehensively, cover all water sources inside and outside the capital, and develop a strategy based on the analysis produced. The strategy includes the need to focus on reducing, reusing and recycling approaches to local water available in Jakarta.

Identification of Saline Water and Fluid Flow in Tanjung Priok and Koja North Jakarta Using Geoelectric Method

To date the cause of saline water in Jakarta area is still debated. One opinion says that salty ground water is caused by sea water intrusion. Other opinions stated that the salty water appears from connate water. The objective of this study is determining the causes of saline water in North Jakarta, especially in Tanjung Priok and Koja. The method used to describe the subsurface fluid flow and resistivity spread is geoelectric method. The method consists of SP (self potential) for fluid flow and resistivity for distribution of subsurface saline water. The data is processed using RES2DINV software and interpreted with processed SP to produce a cross-section map. The results of these two methods are also supported by geological data and wells data samples as well as gravity data in the form of FHD (first horizontal derivative). The results of the resistivity indicate the presence of saline water at a depth of 5-10 meters which is a shallow aquifer. The saline water in this study area most likely caused by the sea intrusion as the SP results show that the subsurface groundwater flows from North to South.
