Abstract

Jerami padi adalah limbah dari pasca panen tanaman padi dimana jerami padi dapat ditingkatkan nilai gunanya menjadi energi terbarukan dengan pirolisis. Pirolisis adalah proses dekomposisi ikatan karbon pada biomassa yang panjang menjadi lebih pendek dengan menggunakan energi panas suhu 300oC-600oC tanpa adanya oksigen. Penelitian ini dilakukan untuk mengetahui efek suhu pirolisis terhadap produk pirolisis(bio-oil, char, dan gas), kondisi optimum untuk menghasilkan bio-oil, dan kandungan senyawa kimia yang terdapat pada bio-oil. Pirolisis yang dilakukan pada penelitian ini pada temperatur 250, 300, 350, dan 400oC. Produk utama dari pirolisis adalah produk cair yang disebut dengan bio-oil. Gugus asam karboksilat menunjukkan intensitas gelombang paling tinggi dibandingkan dengan gelombang yang lainnya pada Analisa FTIR Jerami padi. Bio-oil terbanyak didapatkan pada suhu 300oC dan pada suhu 250oC didapatkan nilai pH terendah serta memiliki densitas tertinggi. Semakin tinggi suhu pirolisis maka produk gasnya semakin tinggi dan produk char semakin menurun. Berdasarkan Analisa GC-MS produk asam asetat memiliki % (persen) area tertinggi yaitu sekitar 49,45%.  Sehingga suhu optimum memproduksi bio-oil pada pirolisis jerami padi pada suhu 300oC dan untuk memproduksi char suhu optimum pada 250oC

Abstract

Agiculture waste is an unused by-product from the remnants of agicultural activities. The Impact of agiculture waste is becoming a substance contaminant that can disturb life biotic as well as become a source of disease. Agiculture waste is divided into three goups: waste agiculture pre-harvest, waste agiculture at the moment harvest, and waste agiculture post-harvest. Handling agiculture waste could be conducted by manipulating waste that becomes a product-appropriate use. Agiculture waste that can be utilized is shell coconut waste. Shell coconut waste could be made adsorbent in reducing solids pollutants in geywater. This study used a continuous adsorption column method with adsorbent media engineered from shell coconut waste. So that it can be known the potential of shell coconut waste as an adsorbent in reducing total solids in geywater. Based on analysis using an adsorption test with an isotherm model, the adsorbent product from engineering waste shell coconut can remove 64% of solids suspended in geywater. The adsorption process of the solid suspended follows the Langmuir isotherm model, with capacity adsorption from an adsorbent of 0.0412 mg g-1. Adsorbent waste agicultural products can reduce total solids dissolved in geywater by 3.7%. Therefore, adsorbent products from agiculture waste could become alternative adsorption media in reducing solids pollutants in geywater.

Abstract

The low-rank coal is increasing every year but still slightly exploited by the industry, due to it being caused by the low-calorie value of the low-rank coal waste. Therefore, the mixture of other biomass is expected to raise the calorie value. This approach could potentially make the low-rank coal more economically viable for use in various industries, especially as a source of energy. Additionally, further research and development in this area could lead to more efficient and sustainable energy production methods. The study uses the Central Composite Design with ratio of low-rank coal waste and palm kernel shells of 40%: 60%, 60%: 40%, and 80%: 20% and variations of the glue starch (5 to 7%), which have been optimized and validated using the Response Surface Method approach. The results of the study showed volatile matter, fixed carbon, and calorie values of 61.43% to 71.69%, 16.56% to 26.98%, and 5190.44 to 6330.40 kcal/g, respectively. The results also demonstrated that the glue with 6% variation showed the highest fixed carbon content and calorie value in comparison to the other variations. The optimum of concentration of low-rank coal and palm kernel shell for co-firing of 80: 20% with 5% glue addition resulting in a volatile matter, fixed carbon, calorie value, flame capacity, flammability, of 54.41%, 33.39%, 6192.123 kcal/g, 14.12 min, and 0.052 g/min, respectively. The validation process also met the requirements for SNI 01-6235-2000 and SNI 8675-2018. Overall, the study concluded that the co-firing of low-rank coal waste and palm kernel shell with glue starch can result in an optimized fuel mixture with high performance characteristics. These findings are significant for industries looking to improve their energy efficiency and reduce emissions.

Abstract

Biodegradable foam made from natural starch offers a sustainable alternative to Styrofoam, which is lightweight, low-cost, but challenging to degrade and harmful to the environment. The purpose of this study is to utilize cassava peel waste, which contains starch, as a raw material for producing biodegradable foam using a biocatalyst method approach, thereby reducing the presence of cyanide acid in cassava peel waste. Aside from that, Carboxy Methyl Cellulose (CMC) is used as a filler to strengthen the structure of biodegradable foam with mass variations of 4, 6, and 8 g. The characteristic cassava peel flour results showed that the biocatalyst method, achieved through fermentation, can reduce cyanide acid levels in cassava peel flour. Then, a biodegradable foam with the best characteristics was produced by adding 6 g of CMC, resulting in a thickness of 1.9 mm, a water absorption capacity of 17.45%, a tensile strength of 3.13 MPa, and a biodegradation level of 100%. The resulting biodegradable material exhibits a tensile strength that exceeds that of Styrofoam and can disintegrate completely in the soil.
