Abstract

The increase in the number and activities of the population will be in line with the increase in waste generation, resulting in an increase in the burden on the Ganet landfill. The current controlled landfill method can no longer manage the increasing waste load. A more efficient waste management design system is needed to minimize and prevent potential environmental damage. Waste management scenarios are designed based on the potential for waste processing at the Ganet landfill. In selecting waste management scenarios, an economic analysis is required, which is key in designing an effective waste management system. Cost Benefit Analysis (CBA) is used as an economic assessment of the 4 scenarios designed, namely scenario 0 (controlled landfill), scenario 1 (utilization by scavengers, composting and controlled landfill), scenario 2 (utilization by scavengers, composting, pyrolysis and controlled landfill) and scenario 3 (utilization by scavengers, composting, pyrolysis, paving block making and controlled landfill). The cost and benefit components were identified for each waste treatment process. The waste processing that costs the most is controlled landfill in scenario 0 amounting to IDR 8,326,123,157.87, while the waste processing process that produces the greatest benefit value is the manufacture of paving blocks amounting to IDR 158,392,662.33. The results of the Cost Benefit Analysis calculation show a Benefit Cost Rasio (BCR) value of 1.91, Net Present Value (NPV) of 8,448,737,857.40 and the fastest Payback Period (PP) of 5 months is scenario 3. This shows that the scenario is economically feasible to do. The results of this study are expected to be a consideration in the policy formulation related to waste management at the Ganet landfill.

Abstract

Indonesia is a maritime country composed of 16,771 islands consisting of large islands and small islands. One of the environmental problems that occur in small islands. Waste management is a shared focus because sources of water, soil and air pollution can come from waste. Waste management on small islands is very important because small islands have a much higher vulnerability than large islands.. This article aims to identify and analyze waste management in Indonesia's Small Islands and evaluate if its implementation has utilized the technology and concepts of the Industrial Revolution 4.0. Based on the findings of a review of 14 articles published from 2018-2023, with 15 islands as research objects, it was found that most of the small islands used as research objects had not managed their waste properly. The waste is eventually dumped into the sea. The unmanaged factor of this waste can be caused by the geographical conditions on the island which are bordered by the sea, the lack of waste management facilities, the limited land area on small islands and the low awareness and participation of the community in waste management. The rest, several islands have carried out the process of storage, processing, collection and destruction quite well. The waste is turned into handicrafts (bags and souvenirs), ecobricks, garden decorations and plant fertilizers for organic waste as well as the development of innovative waste into diesel fuel. Unfortunately, the intended application based on the Industrial Revolution 4.0 has not been reflected in waste management on these small islands. This is expected to be information and input for the government and managers as a model for other small islands in an effort to manage waste generation on the island's mainland and garbage contamination in the sea.

Abstract

Peran perempuan sangat diperlukan dalam rangka memecahkan permasalahan lingkungan yang salah satunya diakibatkan oleh sampah. Peran ibu rumah tangga sangat penting dalam pengelolaan sampah karena ibu memiliki peran sentral serta pionir dalam keluarga untuk memulai meminimalkan jumlah produksi sampah di dalam rumah tangga. Berdasarkan hasil penelitian yang dilakukan kepada ibu rumah tangga yang tergabung dalam Majlis Ta’lim Al-Jalil, diketahui bahwa peran ibu rumah tangga dalam pengelolaan sampah secara umum berkategori antara sedang hingga sangat tinggi. Keterlibatan perempuan dalam pengelolaan sampah rumah tangga pada proses penampungan dan pemilahan adalah sangat tinggi (100%), dimana laki-laki hanya terlibat 43,33% pada proses pengangkutan sampah ke tempat pembuangan akhir. Peran ibu rumah tangga dalam menyediakan tempat penampung sampah yang memenuhi persyaratan adalah sedang (56,67%). Peran ibu rumah tangga dalam melakukan pemilahan adalah sangat tinggi (80%). Tingkat pengetahuan ibu rumah tangga paling banyak terdapat pada kategori baik (73,3%). Dukungan dan antusias ibu rumah tangga untuk berpartisipasi dalam program pemberdayaan khusus perempuan dalam pengelolan sampah juga tinggi (66,67%). Dari hasil tersebut dapat membuktikan bahwa ibu rumah tangga juga mempunyai keterlibatan dalam melakukan pembangunan lingkungan yang dalam hal ini ada pengelolaan sampah

Abstract

Senyawa hidrokarbon yang terkandung di dalam minyak bumi sangat berbahaya jika masuk dan mencemari perairan laut. Perlu dilakukannya pendekatan yang dapat menanggulangi terjadinya pencemaran minyak bumi di perairan laut. Salah satu pendekatan yang dapat digunakan adalah pendekatan secara biologis dengan bioremediasi. menggunakan bantuan bakteri hidrokarbonoklastik yang dapat mengikat, mengemulsi, mentranspor serta menguraikan bahan cemaran. Riview literatur ini bertujuan untuk mengidentifikasi jenis bakteri hidrokarbonoklastik dari perairan Indonesia.  Beberapa jenis bakteri hidrokarbonoklastik yang ditemukan dalam penelitian bioremediasi 10 tahun terakhir (2012-2022) dalam website https://scholar.google.com adalah Bacillus, Pseudomonas, Klebsiella, Enterobacter, Citrobacter, Alcanivorax, Halomonas, Raoultella, Alphaproteobacteria, Firmicutes, Vibrio alginolyticus, Alcaligenes, Micrococcus, Halobacillus serta Rhodobacteraceae. Bakteri - bakteri ini terbukti dapat mendegradasi cemaran minyak bumi di perairan laut baik secara tunggal maupun konsorsium dengan persentase kemampuan degradasi sebesar 22,2% - 100%. Dengan memanfaatkan bakteri-bakteri ini secara optimal, dapat membuka peluang untuk pengembangan strategi bioremediasi yang lebih efektif.
