Abstract

Mining operations always involve a number of environmental interactions. Sand mining operations degrade the surrounding environment, causing significant physical damage to the landscape and possibly making the area more vulnerable to air pollution, flooding and landslides. A national private company called PT X has conducted exploration and feasibility studies. In calculating losses due to pollution, the analysis method is the replacement cost method. The disease cost analysis approach is used in data analysis to calculate economic losses due to post-mining pollution. From the results of the analysis that has been carried out, it is known that the location of the mining business activity has an estimated quartz sand reserve of 7,708,637 tons with a mining plan of 300,000 m3 / year and this calculation shows that each resident is entitled to receive a replacement cost of Rp.1,542,807 / month. The result of the calculation of the total environmental damage recovery value is Rp.1,482,521,465. The results of the post-mining damage analysis show that the application of mining can have a negative impact on the environment and society.

Abstract

AbstrakKecamatan Ngabang merupakan salah satu induk dari kota kabupaten Landak yang mengalami berbagai perkembangan dalam berbagai sektor. Adanya perkembangan di berbagai sektor membuat aktivitas masyarakat bertambah dan peningkatan jumlah hasil buangan makin meningkat. Buangan sampah ini kebanyakan dihasilkan dari kegiatan domestik/ rumah tangga yang mana pada tahun 2022 jumlah estimasi timbulan 32,2 ton/perhari. Jumlah unit yang dimiliki Kecamatan Ngabang yaitu truk angkut 9 unit dan TPS kontainer 13 unit. Pengelolaan sampah Kecamatan Ngabang  dirasakan belum efektif karena masih adanya penumpukkan sampah di sekitar TPS karena kepenuhan. Adanya permasalahan tersebut maka penelitian ini diangkat bertujuan untuk mengidentifikasi permasalahan dan menganalisis kelayakan sistem serta unit pengelolaan sampah dalam menunjang timbulan sampah yang ada di Kecamatan Ngabang. Kebutuhan unit diproyeksikan menggunakan rumus geometrik, ketersediaan daya tampung TPA ditinjau dengan jumlah timbulan sampah. Hasil analisis kebutuhan TPS/kontainer diketahui total kebutuhan tahun 2024 sebanyak 26 unit dan kebutuhan truk angkut sampah sebanyak 17 unit. Analisis ketersediaan kapasitas TPA dalan jangka waktu 20 tahun kedepan diketahui hasil bahwa ketersediaan daya tampung TPA masih dapat menampung timbulan sebanyak 61.533,33 m3. Hasil dari kajian diketahui bahwa adanya penumpukkan sampah kecamatan Ngabang dikarenakan ketersediaan unit pengelolaan sampah yang masih kurang serta belum dapat menunjang timbulan sampah yang ada. Kata kunci: kebutuhan unit, pengelolaan sampah, proyeksiAbstractNgabang sub-district is one of the main cities of Landak district, which has experienced various developments in various sectors. The development in various sectors has increased community activities and increased the amount of waste products. This waste is mostly generated from domestic/household activities, which in 2022 will generate an estimated 32.2 tons/day. The number of units owned by Ngabang Sub-district are 9 haul trucks and 13 container TPS. Waste management in Ngabang Sub-district is not effective because there is still accumulation of waste around TPS due to fullness. The existence of these problems, this study aims to identify problems and analyze the feasibility of waste management systems and units in supporting waste generation in Ngabang Sub-district. Unit needs are projected using the geometric formula, the availability of landfill capacity is reviewed by the amount of waste generation. The results of the analysis of TPS/container needs showed that the total need in 2024 was 26 units and the need for garbage trucks was 17 units. Analysis of the availability of landfill capacity in the next 20 years shows that the availability of landfill capacity can still accommodate 61,533.33m3 of waste. The results of the study show that the accumulation of waste in the Ngabang sub-district is due to the availability of waste management units that are still lacking and have not been able to support the generation of waste. Keywords: Unit Requirements, Waste Management, Projection
