Abstract

Straw is a waste produced from the threshing and harvesting of rice. So far, rice straw has only been removed. In fact, it can be used as a potential energy source. This paper aims to examine the potential of rice straw as a renewable energy source in Indonesia. Opportunities and challenges were evaluated based on extensive and in-depth literature review. The paper discussed rice straw potential, its characteristics and benefits of using straw energy. Technology to convert rice straw into energy was also discussed. Results showed that renewable energy potential of rice straw is 28.8 TJ/year. Conversion technologies that can be applied include densification, combustion, gasification, and biogas. The biggest challenge for using rice straw energy is collection and transportation. Densification may overcome density problem by producing high quality pellets or briquettes that reduce transportation and storage costs. Straw characteristics need to be improved to increase its combustion properties.

Abstract

Kebiasan masyarakat membuang sampah ke badan air menjadi masalah serius karena sampah terakumulasi di hutan mangrove. Sampah plastik dapat menyebabkan kematian tanaman mangrove dan mengancam kelestarian hutan mangrove di Desa Margasari. Inovasi yang ditawarkan dalam kegiatan pengabdian kepada masyarakat ini adalah eco paving block. Produk ini tidak rumit pembuatannya dan membutuhkan sampah plastik dalam jumlah besar. Tujuan kegiatan ini adalah (1) meningkatkan pengetahuan dan keterampilan masyarakat dalam mengolah dan memanfaatkan sampah plastik dan (2) meningkatkan daya tarik eduwisata Lampung Mangrove Centre. Kegiatan diawali dengan penyuluhan dilanjutkan dengan pelatihan pembuatan paving block. Hasil evaluasi 20 orang peserta menunjukkan bahwa terjadi peningkatan pengetahuan tentang bahaya plastik bagi ekosistem mangrove dan peserta mampu membuat paving block dengan baik. Peserta sangat antusias dan berharap kegiatan ini dapat diduplikasi kepada lebih banyak warga masyarakat.

Abstract

Biomass from oil palm fronds has not been effectively utilized in Central Lampung, there is a need for alternative processing of palm oil fronds into more useful materials. One method of processing palm fronds is to create bio charcoal briquettes, which are used as an alternative fuel. The purpose of this research was to see how palm fronds and particle size of palm oil fronds affected the properties of bio charcoal briquettes. The factorial completely randomized design (CRD) was used in the research with one factor, namely the particle size of the oil palm fronds passing through the sieve with one treatment, namely 20 mesh. To produce 25 experimental units, the study used five treatments with five replications. The obtained material was then tested for LSD. The results revealed that palm fronds had no impact on briquette density, moisture content, compressive strength, shatter resistance index, or rate of burning. The particle size of palm leaves going through the 20 mesh sieve affects density, compressive strength, shatter resistance index, and burning rate significantly. The findings revealed the following features of bio charcoal briquettes: The moisture content is 5.17-6.89%, the heating value is 4372.42 - 5074.50 cal/g a density of 0.568-0.674 g/cm3, a compressive strength of 3.85 - 4.58 kg/cm2, a shatter resistance index of 12.58-17.19%, a burning rate of 1.40-1.47 gram/minute, and a bottom temperature of 287°C. (for 60 minutes and a mass of 200 grams).
