Abstract

Lignocellulosic biomass is a renewable resource used to produce energy, fuels, and chemicals. This study aimed to determine the effect of pyrolysis temperature on product yield and product characterization of bio-oil. In this study, palm shells were selected and prepared as raw materials for bio-oil production. Palm shells were first soaked in 10% HCl and then pyrolyzed at temperatures of 300 oC, 350 oC, 400 oC, and 450 oC in a fixed bed reactor. Afterward, the reactor will emit smoke which later will condense into bio-oil. The experimental results show that a temperature of 450 oC will be a better choice for higher bio-oil yields (44.59%). The characteristics of the bio-oil obtained are density (905 – 1015.17 kg/m3), Kinematic Viscosity (1.21 – 1.5 mm2/s), and flash point (60 – 68.7 oC).

Abstract

Coconut pulps are solid waste from coconut processing that has had its coconut milk extracted, with a remaining oil content of around 12.2–15.9%. The processing of coconut pulp is not yet optimal, and this waste has the potential to be utilized as renewable energy in the form of biodiesel. Biodiesel is produced through an in-situ transesterification process assisted by microwave energy. This study aims to identify the potential environmental impacts of biodiesel production from coconut pulp as fuel. A Life Cycle Assessment (LCA) was conducted using the cradle-to-gate approach with the SimaPro ver. 9.4.0.3 data processing application and a database similar to the eco-invent database. The environmental impact assessment was analyzed using the EF 3.0 Method (adapted) V1.03 / EF 3.0 normalization and weighting set. The results show that among the stages of the biodiesel production process, the transportation of raw materials and supporting materials has the greatest impact on climate change compared to other stages. The transportation stage contributed 78.19 kg CO₂-eq out of a total of 204.35 kg CO₂-eq in the climate change category and dominated energy resource use at 1108.14 MJ out of a total of 1742.17 MJ. In addition, the preparation stage also contributed significantly to climate change, with emissions reaching 56.21 kg CO₂-eq. The large contribution from the transportation stage was mainly caused by exhaust gas emissions from vehicles used to transport raw materials and supporting materials. Based on the LCA results, environmental performance improvements or continuous improvements that can be implemented include optimizing logistics, regulating fuel use, selecting the nearest sources of raw materials, and improving energy efficiency during the preparation stage to support more sustainable biodiesel production from coconut pulp.

Abstract

Program pengabdian masyarakat yang dilaksanakan di SMA Methodist 1 Palembang memiliki fokus pada peningkatan kemampuan para pelajar dalam menciptakan materi edukasi yang inovatif dan sesuai dengan perkembangan zaman digital. Program ini menjadi sangat penting mengingat mayoritas siswa saat ini lebih sering bertindak sebagai penikmat pasif media digital, alih-alih memanfaatkannya sebagai pembuat karya (kreator). Padahal, kemampuan dalam menghasilkan materi pembelajaran sangat dibutuhkan guna memperdalam penguasaan pelajaran, memicu daya cipta, serta menumbuhkan sikap belajar yang mandiri. Guna menjembatani kondisi tersebut, para peserta didik difasilitasi dengan pelatihan yang memanfaatkan dua perangkat utama: platform desain grafis Canva serta teknologi Kecerdasan Buatan (AI) guna mempermudah perancangan materi. Selama proses pelatihan, pelajar dibimbing secara langsung untuk membuat desain presentasi maupun infografis yang tidak hanya memanjakan mata, tetapi juga kaya informasi dan sinkron dengan kurikulum sekolah. Pencapaian yang diharapkan dari inisiatif ini meliputi meningkatnya kemampuan komunikasi visual dan literasi digital peserta, diiringi dengan terbitnya publikasi pengabdian di jurnal nasional ber-ISSN. Untuk jangka panjang, program ini ditujukan untuk mengubah suasana akademik di sekolah menjadi lebih kolaboratif dan interaktif, sehingga generasi muda semakin tangguh dalam merespons tantangan kompetensi abad ke-21.

Abstract

Solar energy can be converted into electricity using photovoltaic systems as a strategic measure to achieve the renewable energy mix targets outlined in the National Energy Policy. Photovoltaic Rooftop (PV Rooftop) systems integrated with Building Integrated Photovoltaics (BIPV) present a viable alternative. PV Rooftop technology is currently trending, as evidenced by its increasing adoption in both industrial and residential sectors, supported by the global decline in solar panel prices. However, from an architectural perspective, silicon-based PV panels can reduce the aesthetic appeal of buildings. An emerging solution promoted by architects worldwide is the implementation of semi-transparent, dye-sensitized solar cells (DSSC), which are sensitive to colorants. In addition to their functional properties, DSSCs offer high aesthetic value due to the pigments used. Urban areas hold significant potential for the development of off-grid DSSC photovoltaic systems installed on rooftops and building facades. This study focuses on the analysis of off-grid DSSC PV systems for a type 42 residential house in Palembang City. The research employs a quantitative approach, using literature review and field measurements, followed by technical calculations. The article details the components required for designing an off-grid DSSC photovoltaic system capable of supplying all household electrical loads.
