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

This study aims to investigate the effect of the KOH/TKKS ratio on the energy content and composition of three-phase pyrolysis products, with a fixed zeolite mass of 10 g. The pyrolysis process was conducted using 100 g of empty fruit bunches (TKKS) at 450 °C with a residence time of 15 minutes. The evaluation covered pyrolysis performance (yields of biochar, bio-oil, and gas), biochar properties (proximate analysis and energy content), bio-oil (energy content), and gas (composition via GC-TCD and energy content). The results show that increasing the KOH ratio accelerated the attainment of the target temperature from approximately 17 minutes (ratio 2:4) to 10 minutes (ratio 4:4) and promoted a higher gas fraction while reducing the bio-oil yield. The optimal condition for bio-oil production was achieved at a KOH/TKKS ratio of 2:4, yielding the highest bio-oil fraction of 29.3%. A higher KOH mass also increased the concentrations of CO, CO₂, and H₂ in the gas phase while decreasing the fixed carbon content in the biochar. The energy input during pyrolysis decreased significantly from 1513.11 kJ at the 2:4 KOH/TKKS ratio to 813.8 kJ at the 4:4 ratio, primarily due to the accelerated heating rate induced by higher KOH content. Despite this, the 2:4 ratio exhibited the highest energy conversion efficiency, as it produced the largest yield and energy content of bio-oil, contributing to a higher total energy output. These findings highlight the critical role of an appropriate KOH ratio in optimizing product distribution and energy efficiency in the pyrolysis process. The results underscore the potential of TKKS as a renewable energy source through microwave-assisted pyrolysis.

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.
