Abstract

In this modern era, electrical energy is the most needed energy. Because a lot of equipment is powered by electricity. As a result, it must be balanced in relation to the availability of electrical energy. To provide enough electrical energy, a power plant is required. One of the promising technologies in the future is the downdraft gasification technology, where biomass can be used as a very abundant fuel in Indonesia. Rice husk, coconut fiber, coconut shell, palm oil waste, and urban waste are some of the biomass materials used. Based on the results of a literature review regarding the composition and calorific value of the syn-gas produced, the easiest biomass to gasify is a combination of palm fronds/palm fronds (OPF) and palm kernel shells (PKS) with a ratio of 20/80. With this composition ratio, it is possible to produce syn-gas with a composition of 21% CO, 3% CH4, and 17% H2 with a heating value of 5850 kJ/m3. It can be concluded that the type of biomass feedstock greatly influences the composition and calorific value of the syn-gas produced. Because each type of biomass produces different syn-gas characteristics.

Abstract

Pada zaman ini, penggunaan bahan bakar minyak minyak (BBM) merupakan kebutuhan energi yang tidak dapat diperbarui yang tidak sebanding dengan meningkatnya jumlah kendaraan sehingga pasokan volume BBM semakin menurun. Selain itu, masalah lingkungan berupa peningkatan jumlah sampah yang juga semakin tinggi dikarenakan proses penguraian yang memerlukan  khususnya pada sampah plastik. Oleh karenanya diperlukan cara mengatasi permasalahan tersebut dengan membuat bahan bakar minyak dengan mengekstrak energi yang terdapat pada sampah menggunakan termal. Pirolisis adalah proses dekomposisi secara kimia-termal pada keadaan tanpa oksigen yang terjadi didalam reaktor. Produk utama dari teknologi ini adalah MHP (Minyak Hasil Pirolisis). Minyak inilah yang diharapkan mampu mengatasi berkurangnya bahan bakar fosil dengan dilakukan pengujian performa MHP pada mesin secara langsung. Pengujian dilakukan dengan melihat kinerja yang dihasilkan dengan melakukan variasi campuran bahan bakar. Emisi gas buang juga dilakukan guna mendapatkan data dari efek penggunaan MHP sebagai campuran BBM. Hal ini ditujukan untuk mengetahui secara keseluruhan bagaimana potensi dari MHP agar nantinya bukannya menghasilkan energi terbarukan tetapi juga ramah lingkungan sehingga menghasilkan energi yang bersih dan berkualitas.

Abstract

Biomass is the fourth largest renewable energy source in the world, accounting for approximately 10% of the total global primary energy supply. Every year, a large amount of teak wood sawdust is produced from the manufacturing of furniture, beds, wooden decorations, and various other products. This waste has no economic value and requires considerable storage space, causing problems in handling and disposal. Therefore, utilizing this forestry residue for biofuel production is a sustainable and economically beneficial approach. However, the main challenge in its utilization lies in its high ash and inorganic mineral content, which can reduce energy conversion efficiency and the calorific value of the product. This study aims to compare the effectiveness of washing methods using water and acid solutions in reducing ash content and increasing the calorific value of teak wood sawdust. The research was conducted experimentally in a laboratory, involving several stages: material preparation, washing treatment (water and acid), drying, ash content and calorific value analysis, and result evaluation. The treatments were carried out at mass ratios of 1:25, 1:50, and 1:75, washed for 2 hours using a magnetic stirrer, followed by filtration, rinsing to neutral pH, and drying at 105 °C for 6 hours. The results showed that washing with 1 M HCl consistently produced a greater mass reduction of teak wood sawdust compared to deionized water at all ratios, indicating that the acid method is more effective in reducing the inorganic content of biomass.

Abstract

Teak sawdust biomass has potential as a solid fuel; however, its high ash and inorganic mineral contents adversely affect its fuel quality and thermal performance. Previous studies on biomass leaching generally evaluated process effectiveness solely based on mass loss after leaching, so the relationship between mass reduction and the actual decrease in ash content has not been fully verified. Therefore, this study emphasizes the verification of ash reduction through proximate analysis as a more representative indicator of biomass quality, while also evaluating its effect on improving calorific value. This study aimed to compare the effectiveness of leaching using deionized water and 1 M HCl in reducing ash content and increasing calorific value. The experiment was conducted using solid-to-liquid ratios of 1:25, 1:50, and 1:75, with 2 h of stirring, drying at 105 °C, followed by proximate and calorific value analyses. The results showed that leaching with 1 M HCl effectively reduced the ash content by 30%, from 2.013% in the raw biomass to 1.402%, whereas leaching with deionized water did not result in a significant reduction in ash content. In addition, the calorific value increased by 1.078 MJ/kg, from 17.629 MJ/kg in the raw biomass to 18.707 MJ/kg after leaching with 1 M HCl. Overall, 1 M HCl exhibited superior demineralization performance compared to deionized water. These findings indicate that acid leaching significantly improves fuel quality by reducing inorganic mineral content and increasing energy density.
