Abstract

Moa Island is one of the remote Indonesian Islands that face the difficulty in accessing clean water, especially during the dry season. One way to get clean water is by drilling for groundwater. The drilled groundwater in Kaiwatu Village on Moa Island, Southwest Maluku Regency, Maluku Province, was analyzed for its content to obtain primary data. Primary data related to the quality of drilled groundwater sources includes chemical, physical, and microbiological parameters. The results of chemical parameters obtained from the test results were <0.01 mg/L fluoride, total chromium, nitrite, nitrate, iron, manganese, zinc, cyanide, lead, <0,001 mg/L cadmium, 17.9 mg/L hardness, sulfate 147.55 mg/L, pH 7.50, and organic substances 2.8 mg/L.  The physical parameter analysis showed a turbidity level of 3.71 NTU, a temperature of 26.8 °C, and a color of 5 TCU. The microbiological parameters obtained by the analysis were 0/100 mL. Primary data was then compared with secondary data, namely environmental health quality standards and air health requirements from Minister of Health Regulation No. 32 of 2017 for chemical and physical parameters, as well as water quality requirements and monitoring from Minister of Health Regulation 416/MENKES/IX/1990 for microbiological parameters. The analysis results using a comparison of primary and secondary data showed that all parameters contained in the primary data had values below the safe limits set by the requirements in the secondary data.

Abstract

Fly Ash and Bottom Ash (FABA) is the waste from burning coal in coal-fired power plants and consists of chemical compounds, such as SiO₂, Al₂O₃, Fe₂O₃, and CaO. This waste poses an environmental challenge and an opportunity for the construction industry. This study conducted a comparative analysis of the composition of FABA from several coal-fired power plants in Indonesia and other countries, such as Thailand, China, Malaysia, France, Italy, and Portugal. In particular, this study assessed the XRF data from several other references. The XRF test data showed significant variations in the FABA content, influenced by coal type, combustion method, and emission management technology. The high SiO₂ content in the Cirebon and Teluk Sirih coal-fired power plants showed potential for pozzolanic applications. Meanwhile, the high Fe₂O₃ in Tanjung Enim and Sudimoro had the potential for metallurgical applications. In addition, the high CaO content of Teluk Sirih allowed its use in lime production and soil stabilization. However, high levels of SO₃, especially in Cirebon, required more attention in processing because of its impact on concrete quality and environmental pollution. With proper processing, FABA could be a valuable resource in various industries, reducing reliance on natural raw materials. This study highlighted the potential for the sustainable use of FABA and proposed management measures to address environmental challenges. The optimal use of FABA reduced negative environmental impacts and opened up significant economic opportunities, supporting the circular economy in the energy and construction sectors.

Abstract

Permasalahan sanitasi lingkungan di kawasan pesisir Muara Angke, Jakarta Utara, khususnya terkait pengelolaan air limbah domestik yang dibuang langsung ke badan air tampa pengolahan, telah menyebabkan penurunan kualitas air serta meningkatkan resiko penyakit bebasis lingkungan. Kegiatan pengabdian masyarakat ini bertujuan untuk menerapkan teknologi Instalasi Pengolahan Air Limbah (IPAL), serta melakukan analisis pasca pengoprasian guna mengevaluasi kinerja dan efektivitas sistem yang telah dibangun. Metode yang digunakan survei awal, perancangan IPAL dan untuk mengetahui kondisi pengelolaan sarana tersebut dilakukan dengan metode pendekatan deskriptif kualitatif yakni dengan mendeskripsikan kondisi pengelolaan sarana sanitasi berdasarkan hasil kuisioner masyarakat yang terkena dampak IPAL Muara Angke. Tingkat kepuasan meliputi pengetahuan, kebermanfaatan, hasil kualitas air, dampak, dan penerapan IPAL. Hasil pengabdian ditunjukkan dengan teknologi IPAL yang telah terpasang di Muara Angke dan hasil analisis menunjukkan bahwa tipologi pengelolaan IPAL adalah : Aspek hasil pengelolaan air yang berada pada posisi pertama dengan nilai 95%, aspek kebermanfaatan dan dampak positif yang pada posisi kedua dengan nilai 90%, aspek pengetahuan dan kemudahan penerapan yang berada pada posisi terakhir dengan nilai 87,5%. Berdasarkan data yang diperoleh didapatkan hasil yang baik mengenai tingkat kepuasan masyarakat terhadap IPAL. Kegiatan ini diharapkan menjadi model replikasi pengelolan air limbah di wilayah pesisir perkotaan.
