Abstract

Meningkatnya produksi biodisel sebagai bahan bakar mengakibatkan meningkatnya jumlah crude gliserol sebagai hasil samping. Untuk itu diperlukan beberapa perlakuan untuk memanfatkan gliserol tersebut dengan cara memurnikannya. Penelitian ini bertujuan untuk mengetahui rasio berat asam fosfat yang terbaik pada proses asidifikasi dan persen berat adsorben limbah cangkang telur ayam pada proses adsorpsi untuk menghasilkan kemurnian gliserol dengan kadar yang tertinggi. Percobaan diawali dengan pretreatment gliserol dengan asam fosfat dengan variabel uji rasio berat (b/b) asam yang ditambahkan (1:0,2; 1:0,4; 1:0,6; 1:0,8 dan 1:1), dilanjutkan dengan adsorpsi menggunakan limbah cangkang telur ayam yang sudah diaktivasi secara termal dengan variabel uji persen berat adsorben (%b/b) 3%, 6%, 9%, 12% dan 15% dengan kondisi reaksi kecepatan pengadukan 250 rpm dan waktu adsorpsi 120 menit. Hasil kemurnian terbaik didapatkan pada rasio berat (b/b) asidifikasi 1:0,6, persen berat adsorben (%b/b) 15% dengan kadar gliserol sebesar 67,22%, densitas 1,171 g/cm3, kadar air 2,796%, kadar abu 13,852% dan kadar MONG 16,130%. Hasil analisa gliserol yang sudah dimurnikan belum memenuhi standard gliserol komersial berdasarkan British Standard 2621:1979 dimana kadar gliserol harus >80%, densitas 1,2671 g/cm3, kadar air <10%, kadar abu <10% dan kadar MONG <2,5%.

Abstract

This study investigates the production of biobriquettes from a mixture of oil palm frond waste and water hyacinth using durian seed flour as a sustainable adhesive. Biobriquettes were fabricated with varying mass ratios of oil palm frond to water hyacinth (25:75, 50:50, and 75:25) and adhesive concentrations (5%, 10%, 15%, and 20%). Durian seed flour was selected for its starch content, offering an eco-friendly alternative to conventional adhesive like tapioca flour without competing with food resources. Slow primary carbonization (pyrolysis) was employed as the fabrication method. The produced biobriquettes were analyzed for moisture content, ash content, volatile matter, fixed carbon, and calorific value. The optimal formulation was identified at a 75:25 ratio of oil palm frond to water hyacinth with 15% durian seed flour adhesive, yielding a moisture content of 5.91%, volatile matter of 13.97%, ash content of 3.05%, fixed carbon content of 77.07%, and a calorific value of 6,400.78 cal/g. These results demonstrate the potential of durian seed flour as an effective adhesive and highlight the feasibility of utilizing agricultural and invasive biomass wastes to produce high-quality, sustainable biobriquettes.

Abstract

Community service is a form of movement in making a real contribution to society which aims to provide solutions to real problems that occur in society. Most of the Indonesian population still relies on the agriculture, plantation and livestock sectors to drive the economy. By-products in the form of waste are generally used as fertilizer which can actually be used as an alternative energy source. Biogas is a renewable energy produced through the process of anaerobic digestion of organic materials which is currently widely used by the community as an alternative energy to replace LPG for cooking and generator fuel to produce electricity. One of the utilization of non-hazardous biomass waste into energy in the form of biogas has been implemented in Tadukan Raga village in Sinembah Tanjung Muda (STM) Hilir District, Deli Serdang Regency which has been operated since 2018 and is equipped with a barn for mushroom cultivation. However, problems arise where the facility is abandoned where there is a lack of maintenance of biogas generation facilities and mushroom barns, lack of human resources and low understanding of the community, especially BUMDes in the management, development and business maintenance of this facility. Therefore, it is necessary to provide counseling and training to the community in the operation of biogas facilities, revitalize mushroom barns in biomass non-b3 waste utilization facilities and modify LPG stoves into biogas stoves and install stoves in residents' homes around Tungkusan hamlet. Tadukan Raga Village itself is a fostered village that has been used as a place for counseling and service from the University of North Sumatra to the community because there are still several things that need to be improved, so counseling is again carried out in this village.

Abstract

Biogas is renewable energy that can be used as substitute of LPG and generator fuel. One of the uses of non-B3 biomass waste into energy has been implemented in Tadukan Raga village in Sinembah Tanjung Muda (STM) Hilir District, Deli Serdang Regency, which has been operating since 2018. This facility consists of a biogas producing unit and mushroom grumpy. This biogas unit is only capable of producing biogas which can be distributed to 20 points of the house, and the mushroom grumpy is also only limited to one type of mushroom, namely straw mushrooms. Apart from that, mushroom grumpy as a container for growing straw mushrooms is done by using empty oil palm bunches mixed with cow rumen. Therefore, the University of North Sumatra Community Service Institute conducted: (1) Operational training for biomass reactors through making starters to increase biogas production in facilities for utilizing non-hazardous biomass waste into energy (2) Addition of biogas piping networks and biogas stoves to nearby residents' homes. at facilities for utilizing non-B3 biomass waste into energy (3) Training on the decomposition of non-B3 biomass waste through the cultivation of straw mushrooms at facilities for utilizing non-B3 biomass waste into energy (4) Counseling on downstreaming of straw mushroom products at facilities for utilizing non-B3 biomass waste into energy.
