Abstract

Penelitian ini dilakukan untuk mengetahui besarnya Intensitas Hujan di kawasan Aerocity X yang kemudian akan dipakai untuk penentuan dimensi saluran drainase di Aerocity X. Intensitas hujan adalah jumlah curah hujan yang dinyatakan dalam tinggi hujan atau volume hujan persatuan waktu. Besarnya intensitas curah hujan berbeda-beda tergantung dari lamanya curah hujan dan frekuensi kejadian. Intensitas curah hujan ini sangat penting untuk perencanaan debit banjir rencana. Perhitungan dilakukan menggunakan data curah hujan yang terdapat pada pos pengamatan hujan disekitar Aerocity X, yaitu pos hujan Pakubeureum TAMBEN, Jatiwangi TAMBEN, dan Kadipaten TAMBEN. Nilai intensitas hujan didapatkan dengan mengubah data curah hujan harian maksimum menggunakan metoda statistik yang umum digunakan dalam aplikasi hidrologi, yaitu metode Van Breen, Bell Tanimoto, dan Hasper Der Weduwen. Besarnya intensitas hujan yang diperoleh di subtitusikan kedalam rumus Talbot, Sherman, dan Ishiguro dan dibandingkan dengan harga intensitas hujan awal kemudian dipilih metode yang mempunyai nilai standar deviasi terkecil. Hasil perhitungan menunjukan bahwa metode intensitas hujan yang terpilih adalah Metode Van Breen dengan Persamaan Talbot dengan PUH 2, 5, 10, 25, 50 dan 100 tahun.

Abstract

Kota Sukabumi termasuk ke dalam kategori kota sedang yang setiap harinya akan menghasilkan sampah dari hasil aktivitas penduduk yang di dominasi oleh sampah organik sebesar 46.64%. Terdapat satu Tempat Pemrosesan Akhir (TPA) di Kota Sukabumi, yaitu TPA Cikundul yang masih menggunakan sistem open dumping. Timbunan sampah organik akan mengalami proses dekomposisi secara anaerobik di tempat pemrosesan akhir yang akan menghasilkan gas berupa gas landfill, salah satunya merupakan gas metan (CH4). Gas yang dihasilkan dari TPA apabila tidak dikelola dengan baik dapat memberikan dampak buruk terhadap lingkungan. Estimasi emisi CH4 menggunakan IPCC pada tahun 2023 adalah sebesar 0,818 Gg, sementara dengan menggunakan LandGEM sebesar 0,544 Gg, terdapat hasil hitung lebih rendah 33%dibanding metode IPCC.  Tercatat total potensi energi listrik yang di hasilkan dari pemanfaatan emisi CH4 pada tahun puncak 2024-2026 emisi CH4 sebesar 0,524 MWh. Pemanfaatan LFG di TPA yaitu gas metan merupakan salah satu pendekatan yang baik dari segi penghematan energi dan pengurangan polusi udara akibat LFG yang memberikan dampak terhadap pemanasan global.

Abstract

Currently, 24.5% of the population of Bima City lack access to sanitation. The issue is predominantly concentrated in densely populated urban slums along the riverbanks, influenced by the cultural and societal context of Indonesian society. From 2021 to 2022, a comprehensive mixed-method study was conducted in three urban slums, applying the Integrated Framework for Sanitation Services (IFSS) to explore individual aspects within a socio-cultural context. Combining quantitative and qualitative methods, the research involved a household questionnaire survey and in-depth interviews (IDI). The study revealed that individual aspects are shaped by perceptions of the convenience of open defecation and latrine use as well as experiences with shared latrines, driving the adoption of private latrines. Challenges such as financial constraints and limited construction capabilities in urban slum communities often hinder latrine construction, though cultural and traditional values (adat) in the Bima community in urban slums help to alleviate these obstacles. A recommendation is made to enhance the monitoring of sanitation adoption progress, focusing on the sanitation system’s functioning and adherence to the sanitation hierarchy. Despite awareness of the importance of safe disposal, its impact on sanitation behavior in Bima City’s urban slums has been constrained, underscoring the imperative for effective behavior change communication strategies.

Abstract

Bandung City is one of the highest solid waste-producing cities in Indonesia. Waste management needs to be organized so that the waste produced does not harm urban areas. One example of waste management is providing temporary waste storage sites (TPS) as intermediate transfer stations. One hundred fifty-six permanent TPS operates in Bandung, spread over 30 sub-districts with various conditions, both running well and unsuitable conditions affecting waste handling. This study aims to identify the condition of TPS waste management in the city of Bandung and evaluate it based on technical criteria for appropriate TPS buildings. The method for assessing the feasibility of TPS is assessed using 17 criteria, including criteria for TPS buildings and facilities. The evaluation was carried out at 44 TPS in Bandung. The evaluation results show seven criteria for transfer stations with a high degree of conformity and ten for a low level of conformity. The evaluation results resulted in the need for efforts to improve and develop TPS so that it can be used according to the criteria.

Abstract

As the population increases, the amount of plastic waste, especially styrofoam, is also increasing. Styrofoam waste that is not disposed of and accumulates will have a negative impact on health and the environment. On the other hand, the utilization of styrofoam waste as an additional material for building materials is still very minimal. Therefore, this research aims to overcome environmental problems by utilizing styrofoam waste in making paving blocks as an alternative building material. This research uses a quantitative method to determine the quality of paving blocks produced from a mixture of styrofoam and silica fumes. The research process begins with paving blocks containing 10% styrofoam from the total sand, with variations in particle size that pass the mesh sieve of 1mm, 4mm, and 10mm. Styrofoam acts as a partial replacement for coarse and fine aggregates. In addition, silica fume was added as much as 10% of the total cement to partially replace the adhesive material. The results showed that the addition of styrofoam waste with a diameter of 1mm, 4mm, and 10mm mesh passes in paving blocks produced compressive strength values of 18.00 MPa, 29.17 MPa, and 32.34 MPa, respectively, as well as water absorption values of 6%, 4.9%, and 3.6%. The larger styrofoam shredding diameter (10mm mesh) produced the highest compressive strength value (32.34 MPa) and the lowest water absorption (3.6%), meeting SNI 03-0692-1996 and quality classification B for parking lots. The best composition is the addition of styrofoam by 10% of sand and silica fume by 10% of cement, with 10mm mesh shredding diameter. The styrofoam shredding diameter proved to have a significant effect on increasing the compressive strength and decreasing the water absorption of paving blocks. This research is expected to provide a practical solution in reducing styrofoam waste by using it as a building material, while producing paving block products that meet quality standards.
