Abstract

Ketersediaan air bersih merupakan masalah krusial di Dusun Puripan. Kondisi geografis dusun pada dataran rendah menyebabkan sumber air tanah sulit didapatkan. Akibatnya, masyarakat bergantung pada air hujan yang ditampung di Waduk. Air Waduk ini memiliki kualitas yang buruk, yaitu keruh dan berbau, sehingga tidak memenuhi standar kesehatan dan kebersihan yang ditetapkan oleh Peraturan Menteri Kesehatan No. 32 Tahun 2017. Program Pengabdian Masyarakat ini bertujuan untuk meningkatkan kualitas air dari Waduk agar layak digunakan untuk kebutuhan sehari-hari. Metode yang diterapkan meliputi tiga tahap. Pertama, Persiapan, berupa survei lokasi dan kualitas air serta penentuan titik pemasangan alat. Kedua, Sosialisasi, untuk memberikan wawasan tentang pentingnya air bersih sesuai standar. Ketiga, Pemasangan Alat Filtrasi PVDF Membrane with Lining 5000 L pada sistem perpipaan, yang ditempatkan di antara pompa dan tandon. Hasil kegiatan menunjukkan antusiasme tinggi dari warga yang didorong oleh tingginya kasus penyakit akibat air kotor. Pemasangan alat filtrasi berbasis teknologi PVDF Ultrafiltrasi (UF) Membrane berhasil menyaring air Waduk yang keruh menjadi air bersih sebelum didistribusikan ke rumah-rumah. Program ini berhasil terlaksana dengan sukses, meskipun terdapat kendala akses geografis. Diharapkan program ini dapat meningkatkan penggunaan air bersih, mengurangi risiko penyakit, dan menjadi model solusi bagi daerah lain yang menghadapi masalah air serupa.

Abstract

Natural rubber (NR) and Nitrile Butadiene Rubber (NBR) exhibit poor miscibility due to their differences in their solubility parameters. To improve compatibility, a PAN-co-PMMA compatibilizer was synthesized by copolymerizing acrylonitrile (AN) and methyl methacrylate (MMA) with potassium persulfate (K2S2O8) as the initiator. This study investigates the influence of initiator concentration on the characteristics of PAN-co-PMMA and evaluates the mechanical performance of NR/NBR blends incorporating the compatibilizer for rubber seal applications. PAN-co-PMMA was synthesized using a water-ethanol co-solvent at 65°C for 3 hours with a stirring speed of 400 rpm, using initiator concentrations of 1, 2, 3, dan 4 %wt and an AN: MMA ratio of 90:10 (%wt). The drying was conducted at 100°C for 3 hours. IR analysis confirmed successful copolymerization through the appearance of characteristic C≡N and C=O absorption bands. The addition of PAN-co-PMMA reduced curing time and significantly enhanced the tensile strength of the NR/NBR blends.

Abstract

Although groundwater is the primary source of clean water for most Indonesians, its quality is often compromised by physical and chemical parameters that exceed safe limits, such as high turbidity, a pungent odor, and excessive concentrations of iron (Fe) and manganese (Mn). This study focused on testing the effectiveness of groundwater purification using activated carbon filter media in a Fiber Reinforced Plastic (FRP) tube filtration system. This study evaluates filtration performance in accordance with the Environmental Health Quality Standards (SBMKL) for sanitation and hygiene purposes, as stipulated in Regulation of the Minister of Health (Permenkes) of the Republic of Indonesia No. 2 of 2023. The experimental results show that the activated carbon filter operates efficiently; it is capable of reducing turbidity by up to 85%, significantly eliminating odors, lowering iron (Fe) levels to meet the quality standards of Permenkes No. 2 of 2023, and reducing the concentrations of manganese (Mn), nitrate, nitrite, and Cr⁶⁺ which were already within the standard range from the outset. Thus, the effluent analysis confirms that the treated water meets regulatory standards and is suitable for daily sanitation needs.
