Increasing access to proper sanitation in urban areas in Indonesia has not been accompanied by the availability of a domestic wastewater disposal system that is safe for the environment. The existing domestic wastewater management system is felt to be unable to prevent pollution. Several studies have reported contamination of water bodies in several cities originating from domestic wastewater that has not been appropriately managed. This paper aims to discuss the developments of the domestic wastewater management system in Indonesia by exploring the current conditions and challenges. The service capacity and application of domestic wastewater treatment technology at wastewater treatment plants already operating in Indonesia will be discussed to find out the existing comparisons. Several regulations related to the domestic wastewater management system also be reviewed to find out the policy direction of pollution prevention efforts. From the conditions exposed, it is necessary to evaluate and adjust the existing concepts to the progress of developments in the field. More significant effort is needed to find solutions for problems and realize the domestic wastewater management system’s implementation to achieve the desired goals.
Penelitian ini dilaksanakan pada PT. X yang bergerak pada bidang industri pertambangan dan penjualan batubara. Tujuan dari penelitian ini adalah untuk mengetahui proses pengolahan air limbah, dosis dan efektivitas penggunaan Alumunium Sulfat untuk menurunkan kadar Total Suspended Solid (TSS) serta biaya yang harus dikeluarkan perusahaan dari penggunaan Alumunium Sulfat pada pengolahan air limbah tersebut. Metode yang digunakan dalam penelitian ini adalah metode survei, dan pendekatan yang dilakukan dalam menganalisa data-data yang didapatkan adalah dengan menggunakan metode deskriptif-kualitatif. Selain hasil pengukuran dan pengamatan dilapangan, data primer lainnya didapatkan dengan melakukan wawancara secara mendalam(indepth interview) pada responden yang dinilai dapat menjadi sumber informasi yang baik. Hasil dari penelitian ini disimpulkan bahwa sumber air limbah penambangan batu bara merupakan run-off di areal Pit B yang berasal dari mata air yang berada di sekeliling dinding Pit B (area tambang) dan air limpasan hujan yang bercampur dengan lapisan over burden (OB) pada saat dilakukan kegiatan penambangan batu bara. Pengolahan air limbah kegiatan penambangan batu bara yang ditujukan untuk mengurangi kadar TSS pada air limbah tambang, dilakukan dengan teknologi pengolahan aktif. Efektivitas penggunaan Aluminium Sulfat (tawas) untuk menurunkan kadar konsentrasi parameter TSS dengan dosis yang telah ditentukan PT. X adalah sebesar 86,74 %.
Almost all cities in Indonesia have not had sewer systems that are qualified for the excellent standard. As a province capital, Banda Aceh has also been facing several domestic wastewater management problems. Based on several previous reports, the water body in Banda Aceh has been contaminated by domestic wastewater pollution. Therefore, serious attention is needed to overcome the problem, such as analysis, investigations, and concepts. This paper aimed to review domestic wastewater management in Banda Aceh and describe the concepts that can be used to solve those problems. The analytical methods used in this study were spatial and descriptive analysis. This study’s result was the development of concepts of domestic wastewater management system for preliminary planning in Banda Aceh, which has been considered to be needed as the alternative solution.
Penelitian ini dilaksanakan di Kota Banda Aceh, provinsi Aceh dengan mengambil sampel pada sejumlah restoran dan rumah makan berizin di Kota Banda Aceh. Tujuan utama dari penelitian ini adalah untuk mendapatkan data potensi limbah minyak jelantah yang dihasilkan dari restoran dan rumah makan di Kota Banda Aceh yang nantinya akan dipakai sebagai data awal dalam penentuan kebijakan pengelolaan limbah minyak jelantah sebagai sumber energi alternatif yaitu biodiesel. Metode yang digunakan dalam penelitian ini adalah metode deskriptif analitis dengan pendekatan kuantitatif dimana untuk mendapatkan jumlah potensi limbah minyak jelantah dilakukan dengan menggunakan metode statistik dengan pengambilan sampel populasi secara acak. Hasil dari penelitian ini adalah didapatkannya besaran jumlah potensi limbah minyak jelantah yang dihasilkan oleh sebanyak 52 restoran dan rumah makan berizin yang ada di kota Banda Aceh yaitu sebesar 184,956 liter per harinya.This research was conducted in the city of Banda Aceh, Aceh province by sampling a number of licensed restaurants in the city of Banda Aceh. The main objective of this study was to obtain data on the potential waste of used cooking oil from restaurants in the city of Banda Aceh which would later be used as preliminary data in determining the management policy of waste cooking oil as an alternative energy source, namely biodiesel. The method used in this study was a descriptive analytical method with a quantitative approach where to obtain the potential amount of waste used cooking oil is done using statistical methods with randomly population sampling technique. The results of this study are obtaining the potential amount of waste cooking oil produced by as many as 52 licensed restaurants and food court/shop in the city of Banda Aceh, amount to 184,956 liters per day.
