Abstract

Groundwater in DKI Jakarta is subject to microbiological contamination. Approximately 32% of the population in DKI Jakarta relies on groundwater as an alternative source of clean water, highlighting the urgent need to address and prevent contamination. This study aims to investigate the effect of the separation distance between septic tanks and wells on the levels of Total coliform (TC), Escherichia coli (EC), and organic parameter contamination in shallow groundwater. Groundwater quality data, including TC, EC, and organic parameters from 265 monitoring points in DKI Jakarta, was obtained from the Jakarta Environment Agency in 2022. A quantitative descriptive approach, incorporating spatial mapping of bacterial and organic contamination using Geographic Information System (GIS) tools, was employed. MANOVA analysis using SPSS 26 was conducted to determine the relationship between septic tank distances and shallow water contamination levels. Results indicate that the separation distance between septic tanks and wells significantly influences TC and EC contamination in Jakarta Pusat, Jakarta Timur, and Jakarta Barat. Organic contamination, however, is significantly affected only in Jakarta Pusat and Jakarta Timur. In contrast, Jakarta Utara was identified as the most contaminated region, with 84% of groundwater samples showing TC contamination, 55% exhibiting Escherichia coli (EC) contamination, and 69% affected by organic pollution. However, these contaminations were not proven to be influenced by the proximity of septic tanks. This is likely due to the area's coastal location, where hydrogeological conditions and diverse pollution sources play a more significant role in groundwater contamination. Improvements in sanitation infrastructure could significantly enhance groundwater quality, particularly in highly vulnerable areas such as Jakarta Utara.

Abstract

The city of Bekasi was awarded as one of child-friendly cities in Indonesia, by the Ministry of Women's Empowerment and Child Protection in 2022. The city government is committed to fulfilling children's rights, included in a Bekasi City Regional Regulation Number 13 of 2017, concerning child friendly cities. To fulfill children's rights, the Bekasi City government built smart homes to improve child-friendly cities. Smart homes are a facility used for the children, which they use to learn, play and create things, without any charge. Currently, there are 7 smart houses built in Bekasi City, with another 5 being planned to be built in every sub district. The aim of this research was to identify the service coverage of 7 smart houses that serve Bekasi City, and to provide some recommendations for those to be built.  This research used a mixed method, which involved an observation assessment, a score analysis and a spatial analysis. The results of the study showed that, of the 7 smart houses in Bekasi City located in several subdistricts, two were in good conditions (Pondok Gede and Bekasi Timur), three were in moderate conditions (Bekasi Selatan, Mustika Jaya, Rawa Lumbu), and the remaining two were in bad conditions (Medan Satria, Bekasi Utara). It can also be concluded that, based on the service coverage, the Pondok Gede covered another 5 districts, with a distance of 3100 m.

Abstract

Kawasan Tanah Abang, sebagai salah satu pusat kegiatan primer di Jakarta, menghadapi tantangan signifikan seperti kemacetan lalu lintas, kurangnya aksesibilitas, dan urban sprawl yang tidak terkendali. Konsep Transit Oriented Development (TOD) diimplementasikan sebagai solusi untuk meningkatkan integrasi antara penggunaan lahan dan transportasi publik. Penelitian ini bertujuan untuk menganalisis penerapan konsep TOD di kawasan Tanah Abang, dengan fokus pada integrasi transportasi serta dampaknya terhadap aksesibilitas dan keberlanjutan kawasan. Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan pendekatan studi literatur dan analisis spasial. Hasil penelitian menunjukkan bahwa pengembangan TOD di Tanah Abang dapat meningkatkan konektivitas antar moda transportasi, menyediakan infrastruktur ramah pejalan kaki dan pesepeda, serta mendorong efisiensi lalu lintas melalui rekayasa jalan dan pengelolaan ruang publik. Dengan penerapan yang baik, kawasan TOD Tanah Abang berpotensi menjadi lingkungan perkotaan yang berkelanjutan, ramah pengguna, dan mendukung pertumbuhan ekonomi local

Abstract

TOD (Transit Oriented Development) is a concept of developing a mixed area that is integrated with transportation modes. This article aims to analyze the application of the TOD concept in the Istora-Senayan area. Research of The Application of the TOD concept in Istora Senayan area generally combines primary and secondary data. Primary data consists of field observation: recording real conditions of pedestrian paths, cycling infrastructure, transit access, land use, and connectivity. Spatial mapping/GIS analysis: mapping walking distance radius (400-800 m from station), measuring accessibility, block permeability, and connectivity (74,4% of the area within 800m walking distance to transit). Surveys: researchers interpret TOD Indicators (Walking, Cycling, transit, connectivity) into measurable variables and applying scoring methods. Interviews: using design and planning studies to understand stakeholder perspectives and land use problems.  Secondary data: Policy and regulatory documents: TOD Standard (ITDP), DKI Jakarta TOD regulations (Pergub 67/2019), and MRT Jakarta Planning Guidelines. Planning maps and land use data: Land allocation data (residential, commercial, office, etc.) to analyze development patterns and ridership potential. Literature review: Journals, Theses, and urban design documents to define TOD Variable and theoretical frameworks. Data analysis in TOD studies is generally descriptive-quantitative + spatial evaluation, supported by TOD indicator frameworks (e.g., ITDP TOD Standard and Jakarta TOD regulation). Spatial Analysis Interpretation. Spatial analysis explains the relationship between space and TOD performance. A. Walkability Coverage Analysis. 1. Buffer (400–800 m) used to measure walkable catchment. 2. Interpretation: high coverage indicates strong TOD accessibility. Land-Use Mix Analysis. When reviewed based on the concept of TOD, the MRT Istora-Senayan station is included in the TOD development area, because it meets 2 criteria, namely mixed use and proximity to transit points. Based on the results, it can be concluded that the Istora and Senayan MRT Stations have fulfilled and implemented the TOD development concept. This is evidenced by the presence of mixed land use and the integration between the MRT and BRT systems.
