Abstract

Tidal flooding is not only caused by seawater intrusion but also reflects the complexity of urban environmental problems. Contributing factors include land subsidence due to excessive groundwater extraction, inadequate drainage systems, degradation of mangrove ecosystems, and land-use changes resulting from coastal reclamation. Therefore, this study examines the recurring phenomenon of tidal flooding in the coastal areas of Penjaringan District, North Jakarta, particularly in Muara Angke, Muara Karang, and Muara Baru. This study employs a mixed-methods approach through direct field observations, in-depth interviews with residents and community leaders, and the distribution of questionnaires to 100 respondents in the affected areas. The results indicate that tidal flooding has significant impacts on the economic, social, and health aspects of the community. Daily activities are disrupted, household incomes decline, and the risk of disease increases due to poor sanitation conditions during flood events. Although communities have implemented various adaptation measures, most respondents perceive that government interventions have not been effective or equitable. This study emphasizes the importance of collaboration between the government and local communities in developing water control infrastructure, rehabilitating mangrove ecosystems, improving drainage systems, and providing education and economic assistance to enhance the resilience of coastal communities to tidal flooding.

Abstract

This study was conducted to analyse the suitability of the Temporary Waste Management Site (TPSS) location for the appropriate zone based on population, density, and land area in RT 008, Rorotan Village, Cilincing District, North Jakarta. The purpose of this study was to evaluate the suitability of the current TPSS location and to provide data-based recommendations for a more environmentally friendly site that meets community needs. The methodology used was descriptive quantitative with a direct interview approach with 30 randomly selected respondents. Data were analysed by categorising respondents' answers into three groups: agree, disagree, and neutral regarding the suitability of the TPSS location. The results showed a varied distribution of opinions: 43% of respondents agreed because the location is far from residential areas and its cleanliness is maintained; 37% disagreed because of air pollution and the cramped location; and 20% were neutral. The main conclusion is that the TPSS location in RT 008 is highly unsuitable, as it could cause environmental pollution and health problems. This study recommends constructing a wall to reduce unpleasant odours and expanding the TPSS area to accommodate the increasing volume of waste.

Abstract

Dalam pelaksanaan proyek LRT ini, salah satu aspek penting yang sangat menentukan keberhasilan struktur atas adalah sistem pondasi bawah. Mengingat kondisi tanah di sebagian besar trase proyek didominasi oleh lapisan lempung jenuh air, maka dibutuhkan sistem pondasi dalam yang mampu menahan beban struktur atas. Pondasi tiang bor yang telah terpasang juga perlu ditinjau kembali daya dukung dan penurunannya untuk memastikan keakuratan dalam metode pelaksanaanya, sehingga sama dengan hasil perencanaan awal. Untuk itu penelitian ini bertujuan untuk menganalisis kesesuaian antara daya dukung pondasi tiang bor berdasarkan perhitungan analitis menggunakan data uji SPT dengan hasil aktual dari pengujian PDA (Pile Driving Analyzer) pada proyek LRT Phase 1B Velodrome–Manggarai. Metode analisis menggunakan pendekatan hitungan analitis dengan perhitungan daya dukung selimut dan ujung tiang berdasarkan metode Vesic dan parameter geoteknik hasil investigasi lapangan. Perhitungan analitis akan dibandingkan dengan data PDA Test yang dianalisis menggunakan perangkat CAPWAP untuk sepuluh titik tiang bor (Pier-51 sampai Pier-60). Hasil penelitian menunjukkan bahwa nilai daya dukung aktual dari PDA Test selalu lebih tinggi dengan rata-rata nilai sebesar 3040,50 ton dibandingkan hasil perhitungan rencana sebesar 2123,85 ton, sementara nilai penurunan aktual dengan PDA Test mempunyai nilai rata-rata 12,5 mm dan nilai rata-rata dengan cara analitis adalah 32,21 mm. Hal ini membuktikan bahwa perencanaan pondasi yang dilakukan telah memenuhi aspek keamanan dan efisiensi struktur. Selain itu, penggunaan PDA Test terbukti efektif sebagai metode verifikasi kinerja pondasi di lapangan.
