Abstract

Utilization of solid waste raw materials in the form of coconut shells and fly ash as adsrobents for domestic wastewater treatment. This study aims to optimize the effect of coconut shell activated carbon and fly ash with variations in mass ration and stirring time on changes in pH, COD, BOD, ammonia, TSS, and total coliform by adsorption on domestic liquid waste to meet waste quality standards. The research method includes the preparation of activated carbon from coconut shell, SEM characterization and experiments of a mixture of coconut shell activated carbon mass and fly ash (5:10, 10:5, 5:15, 15:5 grams) with variations in stirring time (30 minutes, 60 minutes). The results of the study, the most optimal mixture for changes in pH, ammonia, TSS, COD, BOD, total coliform parameters in domestic wastewater was a mixture of coconut shell activated carbon adsorbent mass of 15 grams and fly ash of 5 grams with a stirring time of 60 minutes.

Abstract

This study investigates the potential of Low-Density Polyethylene (LDPE) plastic waste as a partial substitute for sand in concrete block mixtures, focusing on its effects on compressive strength and water absorption. LDPE is a non-biodegradable plastic waste that poses significant environmental challenges. Its incorporation into construction materials offers a promising solution to reduce pollution while enhancing the performance of building components. The research employed LDPE substitution levels of 10%, 15%, 20%, 25%, and 30% by weight of sand, compared against conventional concrete blocks without LDPE. Experimental results revealed that the highest compressive strength was achieved with a 15% LDPE mixture, reaching 80.762 kg/cm² at 28 days of curing—an increase of approximately 40.8% compared to normal blocks, which recorded 57.359 kg/cm². LDPE additions up to 20% maintained favorable strength characteristics, while higher proportions (25% and 30%) led to a decline in mechanical performance. In terms of water absorption, the inclusion of LDPE demonstrated a decreasing trend, attributed to the hydrophobic nature of plastic, which enhances moisture resistance in the concrete blocks. These findings suggest that a 15% LDPE substitution represents an optimal formulation for producing eco-friendly concrete blocks with improved strength and reduced water absorption. The study highlights the dual benefits of waste management and material innovation, aligning with sustainable development goals. By repurposing plastic waste into construction applications, this approach not only mitigates environmental impact but also contributes to the advancement of green building technologies. Further research is recommended to explore long-term durability, thermal properties, and scalability of LDPE-based concrete products in real-world construction settings.

Abstract

The aim of this research is to develop membrane material and analyse the membrane performance in liquid waste management of CPO industry to separate suspended solids. Conventional waste treatment has not been able to reach the minimum regulatory standards that have been set. Land area constraints and waste management techniques are complex and produce large sludge volumes. Besides specifically for managing liquid organic waste, the difficulty of the process of degradation of waste due to the high quantity and content of contaminants that can reach up to 40,000-120,000 mg / l for COD. In this study composite membrane made by titanium dioxide in the membrane polyvinylidene fluoride was blend very well and suited to remove suspended solids in the wastewater. The optimization result obtained is the addition of TiO2 2% produce maximum flux with the value of 180 L / m2.hr and the percentage of 92% fitration. The results of the filtration process conditions were the total suspended solids (TSS) by 99.63% and ammonium nitrogen (NH3-N) by 92.82% is the ABFR process conditions at 2.25 ml / min, HRT at 276.93 min, MLSS concentration at 4.50 g / L, and the pH at 6.50. So it can be concluded that titanium dioxide resulted the minimise of average poresize and enhance the hydrophilicity of membrane that resulted the maximum flux of this process.

Abstract

Indonesia is an agrarian country with subtropical climate suitable for planting multicultural and one of those plants is sugar cane. Sugar cane is a raw material for producing sugar, where biomass waste has not been utilized appropriately. The amount of biomass waste was produced of 24-30% from sugar mills. Effective, efficient and environmentally friendly waste treatment technology is needed to utilize the waste into a renewable energy source using gasification methods. Gasification is a process to convert biomass waste to combustible gases (CO, CH4, and H2). This process is combustion with limited air supply (20% -40% stoichiometric air) to break long hydrocarbon chains into short hydrocarbons at high temperatures. This method requires an updraft gasifier furnace that is capable of being operated at high temperatures, which can convert biomass waste into syngas with high conversion. An updraft gasifier is a gasification furnace at temperature of 300-500oC and atmospheric pressure, also used air flow of 10-20 L / min and zeolite as catalyst. This research are devided into few steps, namely drying, crushing, separating, gasification process, The proximate and ultimate method was used to analyze the produced syngas. Proximate analysis is an analysis to measure the calorific value by using a calorimeter bomb, ash content used AAF furnace, and moist water content used a decator. Moreover, ultimate method was used to analyze CH4, H2, O2, N2, CO and CO2 compositions by using Gas Chromatography (GC). Firstly, sugarcane bagasse as the main raw material, were dried and chopped in 7 cm then it were put into the gasifier. The results showed that maximum syngas ratio of combustible gas (CO, H2 and CH4) and noncombustible gas (NGC) of 1.03 with added the zeolit of 200 gr and water of 40 ,L/min.

Abstract

Plaju Darat merupakan kelurahan terujung dari Kota Palembang yang berbatasan dengan Kabupaten Banyuasin dengan luas daerah 18,50 Ha. Kontur lahan di kelurahan ini berupa tanah rawa dimana 70% dari luas lahan digunakan untuk pertanian rawa dan sisanya untuk pemukiman. Dengan kondisi lahan yang berupa dataran rendah rawa, memunculkan persoalan tersendiri terkait ketersediaan air bersih. Aliran air bersih dari PDAM Tirta Musi memang telah menjangkau daerah ini, namun belum mencukupi kebutuhan masyarakat. Karenanya masih banyak masyarakat yang menggunakan air sumur untuk keperluan sehari-hari. Ketersediaan air bersih yang belum mencukupi meskipun layanan PDAM telah menjangkau daerah ini sehingga masyarakat masih menggunakan air sumur. Dari permasalahan diatas tim Pengabdian Kepada Masyarakat (PKM) Prodi Teknik Kimia Universitas Muhammadiyah palembang melakukan instalasi penjernih air dengan metode aerasi di salah satu pusat ibadah Kelurahan Plaju Darat yaitu masjid Sirajul Munir Sirajul Munir. Metode yang di terapkan dalam pengabdian dimulai dari 1). analisis situasi kelurahan, 2) merancang sistem instalasi penjernih air, 3) menginstalasi sistem penjernih air, 4) pengujian sistem penjernih air, 5) evaluasi hasil pengabdian. Hasil yang di capai berupa tersedianya sistem  penjernih air beserta peralatan pendukungnya guna menjamin keberlangsungan tersedianya air bersih untuk tempat ibadah masjid Sirajul Munir.

Abstract

Permasalahan umum yang dihadapi oleh sebagian besar UMKM saat ini adalah ketatnya persaingan untuk memasarkan produk yang dapat bersaing dengan berbagai produk sejenis yang diproduksi oleh industri skala besar yang telah lebih dulu dikenal masyarakat. Salah satu hal yang menjadi tantangan bagi produk UMKM dalam persaingan di pangsa pasar umum dan komersial adalah masih relatif terbatasnya kemampuan untuk membentuk citra atau branding produk. Dengan demikian, Produk UMKM tidak hanya dituntut untuk dapat memperbaiki kualitas produk itu sendiri, tetapi yang tidak kalah pentingnya adalah meningkatkan citra produk dengan cara memberikan desain kemasan, logo, dan slogan yang menarik dan spesifik terhadap produknya.  Identifikasi visual tersebut diharapkan dapat membuat produk lebih mudah dikenali saat bersanding dengan produk sejenis di pangsa pasar komersial.  Penyuluhan dan pelatihan yang diberikan kepada masyarakat pelaku UMKM di Bank Sampah Kenanga di Kawasan 19 Ilir Kotamadya Palembang menunjukan peningkatan yang signifikan. Perbandingan hasil pra-test dan post-test pada sesi evaluasi terhadap wawasan dan keterampilan peserta terkait citra produk mereka yang berbentuk sabun padat, eco enzim, dan anyaman dekorasi ruangan berbahan dasar limbah organik menunjukan peningkatan sebesar 45%
