Abstract

Hybrid UF – RO membrane technology is one of the new technologies of separation wastewater from the rubber industry to decrease turbidity and heavy metal contents such as iron and zinc. This technology is being used to replace the conventional installation process of wastewater treatment. Processing wastewater treatment from the rubber industry with the hybrid UF – RO membrane can produce permeate with quality standards, making it possible to be recycled as domestic water for water process in the industry. The technology of wastewater treatment from the rubber industry in this experiment involved the pre-treatment stage, using sand filter and adsorption using calcium carbide residue. The operating variables by flow rate into the UF and RO were 7 and 14 L.Min-1 and operation time were 15 to 90 minutes. The results of this study showed that the percentage reduced were 62.73% for turbidity, 83.28% for iron and 88.89% for zinc, respectively. Finally, it can be concluded that calcium carbide residue was potential to reduced turbidity and heavy metals such as iron and zinc from rubber industry wastewater.

Abstract

Containerization, collection, transportation, and final processing form the basis of the waste management system. These systems all require effective integration. Containment is a crucial basic component of waste management that is carried on to the collection system. An appropriate infrastructure is needed to support this system. Temporary waste storage areas with storage tank amenities are known as trash bins or TPS. The feasibility of TPS infrastructure is discussed in this study starting with the current state, the kind of damage that happened, and suggestions for improving the feasibility findings. The field observations, observations, and references for the TPS eligibility requirements, including SNI 19-2454-2002 and Minister of Public Works Regulation Number 03/PRT/M/2013, were employed as the data collection approaches. The garbage sorting criteria have not been met, according to the identification results, but the waste collection time conditions have been met because there is already a collection and transportation schedule, to not exceed 24 hours.

Abstract

Program pengabdian kepada masyarakat yang diinisiasi oleh tim dari Universitas Sriwijaya dan Politeknik Negeri Sriwijaya dilaksanakan melalui penerapan teknologi membran untuk mengolah air baku menjadi air minum layak konsumsi. Kegiatan ini bertujuan membantu masyarakat dalam memenuhi kebutuhan air minum yang sehat sekaligus membuka peluang pengembangan usaha air minum isi ulang. Kegiatan Pengabdian kepada Masyarakat ini dilaksanakan di Desa Alai Selatan, Kecamatan Lembak, dengan mitra sasaran kegiatan ini adalah Karang Taruna Desa Alai Selatan yang anggotanya berjumlah 28 (dua puluh delapan) orang. Program ini berlangsung selama delapan bulan, terhitung sejak Maret hingga Oktober 2025. Kegiatan ini dilaksanakan dengan merancang rangkaian alat pengolahan air berteknologi membran lalu dilakukan presentasi dan peragaan/demonstrasi cara kerja unit pengolahan air tersebut agar dapat dimanfaatkan dengan baik. Adapun kegiatan ini bertujuan untuk memberi manfaat yang signifikan dan turut membantu pemerintah dalam meningkatkan kesehatan dan kesejahteraan kelompok masyarakat. Untuk mengevaluasi hasil kegiatan, pada akhir kegiatan disebarkan kuesioner sebanyak 40 (empat puluh) lembar ke masyarakat sasaran yang mengikuti kegiatan ini. Berdasarkan hasil pengolahan kuesioner yang telah dibagikan, sebanyak 90% responden dari Desa Alai Selatan menyatakan bahwa program ini memberikan manfaat yang sangat besar. Hal ini menunjukkan bahwa mayoritas masyarakat sasaran memberikan penilaian positif terhadap pelaksanaan kegiatan ini.

Abstract

Subbituminous coal is found abundantly in Indonesia, especially in Sumatra, has significant potential for use as a raw material for briquettes and bio-briquettes. Subbituminous coal is a type of medium-rank coal with low calorific value about 4500-5000 cal/g. Therefore, the combination of coal with coconut shell biomass can increase the calorific value and briquettes quality. This study aims to improve the quality of biobriquettes through variations in carbonization temperature, the ratio of coconut shells to sub-bituminous coal, and the microwave drying. The briquette production conducted with carbonization process in 2 hours with variation temperature used were 300°C and 400°C, and  raw material ratios consisted of 0:100, 25:75, 50:50, and 75:25 with the addition of tapioca adhesive of 15%. Low temperature carbonization (300-400°C) improves fuel quality by removing moisture and volatile matter, resulting in bio-briquettes with high calorific values. The optimal raw material ratio helps reduce combustion exhaust emissions. The charcoal crushed, mixed, casted and dried with microwave drying at 800 Watt. Microwave treatment contributed significantly to the reduction of moisture and ash content. The product briquettes were analyzed based on proximate parameters. The best conditions were achieved at a 75% coconut shell: 25% coal and a carbonization temperature of 300°C, characterized by the highest calorific value (5655 cal/g), the lowest ash content (0.65%), and the lowest inherent moisture (7.74%)  that meets briquette quality standards of PERMEN ESDM No. 47/2006, while the lowest volatile matter (42.93%) and the highest carbon (48.77%) was also achieved in 75% coconut shell: 25% coal.
