Salah satu pencemaran air sungai disebabkan oleh warna yang berasal dari sampah organik rumah tangga atau industri seperti tekstil, keramik dan kertas. Metode adsorpsi merupakan teknik yang efektif dalam memperkecil konsentrasi organik terlarut dan warna dalam limbah. Adsorben yang paling banyak digunakan adalah karbonaktif, akan tetapi karbon aktif yang tersedia biasanya mahal dan tidak ekonomis untuk pengolahan limbah. Karbon aktif akan bernilai ekonomis bila memiliki kemampuan adsorpsi yang tinggi dalam pengolahan limbah dan dihasilkan dari bahan baku yang murah. Adsorben yang digunakan pada penelitian ini adalah karbon aktif kulit durian dengan mencari kondisi optimum konsentrasi aktivator dan suhu aktivasi. Penelitian dimulai dengan pembuatan karbon aktif dengan aktivator Kalium Hidroksida (KOH) dengan konsentrasi 25%, 30% dan 35% (% b/v) dan perbandingan kulit durian dan KOH 2:1, variasi suhu kalsinasi pada 7000C, 8000C, dan 900oC. Penetapan daya serap karbon aktif kulit durian pada warna tekstil dilakukan dengan metoda Spektrofotometri UV-Visible. Hasil penelitian menunjukkan kondisi optimum adsorpsi diperoleh pada konsentrasi KOH 30% dan suhu kalsinasi 800oC. Kata Kunci : Biosorben, Karbon aktif, Kulit Durian, Warna Tekstil.

The waste produced in the city of Serang reaches 360 tons/day, while the waste that can be transported by the Environmental Service (DLH) in the town of Serang to the Final Disposal Site (TPA) is only around 70-80 tons/day. In general, waste management in the community is by burning, throwing it into the river, or collecting it in trash cans to be then taken by the garbage officer and disposed of at the TPA. The same thing also happened in Dalung village, the waste generated from community activities was burned or collected into trash bins to be then taken by officers to be disposed of in the waste landfill. Burning waste causes pollution, and waste disposal in landfill causes degradation of cleanliness and environmental quality due to methane gas which causes global warming, where the gas has a destructive power 23 times stronger than carbon and other gases such as SO2 gas which causes odor. Organic waste can be processed into liquid fertilizer, compost, or methane gas. The implementation of community activities aims to increase public knowledge about the importance of waste management, layout arrangements, and the manufacture of organic and inorganic waste bins as well as training in composting. keywords: fermentation, compost, organic, rubbish

The wastewater in the washing process in Methyl Iso Cyanate production line contains ammonia which causes air pollution. Therefore, the ammonia waste processing system is needed that can degrade ammonia so that its concentration decreases and reduces the pollution. Photocatalytic degradation of ammonia is an attractive technology because of its easy operation, high efficiency, low cost, and low secondary pollutants. The photocatalytic process produces hydroxyl groups from the decomposition of water which can oxidize ammonia into nitrate and nitrogen gas. This research aims to process ammonia waste by combining adsorption and photocatalysis processes to obtain better performance in degrading ammonia. The research began with the preparation of activated carbon as an adsorbent and the synthesis of activated carbon-TiO2 composite material. Activated carbon is heated at 500º C for 6 hours for the activation process. Composite material synthesis is carried out using the slurry method. Activated carbon performance testing was carried out at weight variations of 10, 20 and 30 gram. Measurement of ammonia concentration was carried out using the spectrophotometry method. Optimum results were obtained at an activated carbon weight of 30 gram with a reduction in ammonia concentration of 1.01%. TiO2 as much as 5% of the weight of activated carbon (30 gram) is dissolved in ethanol and activated carbon is added to obtain a composite material. In the composite material performance test, a maximum reduction in ammonia concentration of 45% was obtained using the ultrasonic stirring method.

Effective waste management is essential for achieving a zero-waste environment, particularly in handling hazardous domestic waste like used dry cell batteries. This study explores a sustainable approach by recovering graphite from battery waste to synthesize graphene oxide (GO) for enhancing poly-vinylidene fluoride (PVDF) membranes. GO was synthesized using the Hummers method and a modified high-speed homogenization approach, then characterized via Raman spectroscopy and X-ray diffraction (XRD). The fabricated PVDF-GO membranes were further analyzed using SEM-EDS, AFM, water contact angle measurements, and bacterial rejection tests. Results confirmed successful GO synthesis and integration into the polymer matrix. GO incorporation improved hydrophilicity, reducing the water contact angle from 120° (pure PVDF) to 66° and 56° in PVDF/PVP-GO membranes via high-speed homogenization and conventional methods, respectively. The modified membranes exhibited a 5–6 times larger pore size than pure PVDF and achieved nearly 100% bacterial rejection. Additionally, PVDF/PVP-GO(h) showed a 91.76% faster production time efficiency than PVDF/PVP-GO(s).

Durian (durio zibertinus) is a native tropical fruit from Southeast Asia, especially Indonesia. Durian peel is the highest composition of durian fruit (60-75%), and is still considered as waste that causes environmental problems. This study aimed to analyze the content of secondary metabolites extract, to analyze the anti-bacterial activity of durian peel extract against gram-negative and gram-positive bacteria, and to calculate the effectiveness of durian skin durian peel extract as a natural anti-bacterial ingredient in hand sanitizer products by using the paper disc method. Durian peel was extracted with ethanol to obtain extract solution which was then separated from the solvent and applied as an ingredient for hand sanitizer. The Analysis results showed that durian peel extract contains triterpenoids, alkaloids, and saponins, which are phytochemical compounds that anti-bacterial function. Durian peel extract at concentration of 1% wt. inhibited the growth of Escherichia coli, Salmonella thyposa and Sthapylococcus aureus with a clear zone diameters of 7.4 mm, 8.2 mm and 8.6 mm, respectively. In anti-septic tests, hand sanitizer samples containing durian peel extract showed that the interaction between the concentration of durian peel extract and the sampling duration simultaneously gave a significant effect in reducing the number of microorganism colonies.
