Abstract

The purpose of this study was to determine the effect of leaf weight and storage time of eucalyptus leaves on yield, seniol content, specific gravity, refractive index, and optical rotation. This study used a factorial randomized block design with 2 factors, namely: treatment A (leaf weight) with 3 levels of treatment, namely: A1 = 3000 g A2 = 4000 g A3 = 5000 g, and factor B (storage time) with 3 levels of treatment B1 = 2 days of storage B2 = 4 days of storage B3 = 6 days of storage. Based on the results of the study, the yield of eucalyptus oil ranged from 0.44% - 0.94%, and the cineol content of eucalyptus oil was 46.7%-52.7%. The specific gravity of eucalyptus oil is 0.91%–0.93%. The optimal rotation of eucalyptus oil ranged from -2.16 to -3.94. Based on the Indonesian National Standard SNI 06-3954-2001, the physicochemical properties of eucalyptus oil, namely cineol content, specific gravity, refractive index, optical rotation, and solubility in ethanol 80% have values that meet SNI 06-3954-2001.

Abstract

Initiated by the Christian Private High School, YPKPM Ambon, the strengthening of the Pancasila Student Profile, through one of its programs, motivated the students to be involved in the efforts to reduce the effects of global warming. This activity obtained assistance from the university staffs, especially those who have experiences in the measurements of carbon stocks in forests and other land uses. By the end of this activity, the student could figure out factors that caused global warming and were able to calculate the amount of the carbon stocks stored in various types of land covers. The results of the activity showed that the calculation of the above-surface carbon in the Urban Forest area, for each type, were as follows: dense vegetation (104.57 tons/ha), sparse vegetation (20.09 tons/ha) and Imperata cylindrica land (0.52 tons/ha), therefore, the absorption of carbon dioxide (CO2) stored in Dense Vegetation were 383.43 tons/ha, Sparse Vegetation were 73.68 tons/ha and Imperata cylindrica land were 1.90 tons/ha. This activity also suggested that urban forest areas with Imperata cylindrica closure type needed a land rehabilitation activity such as planting trees.

Abstract

The energy needs of the world including Indonesia continue to increase every year. The most commonly used type of energy sources was dominated by fossil. Fossil energy sources were not environmentally friendly and were predicted to run out in a short period of time. Therefore, the alternative energy sources are needed, such as biomass or better known as bioenergy. The purpose of community service activities in Waai Village, Central Maluku Regency was to increase the community’s knowledge in utilizing biomass as an alternative energy source. The management of agroforestry in Waai village potentially produces many types of non-timber forest products (NTFPs) such as sago (Metroxylon sp.) which has husk as its waste after sago flour had been harvested for food. The implementation of the activity was held from July to August 2023, with activity phases including: social approach to the village government and AM GPM management and continued with visiting the community on Friday 11 August 2023. PKM activities were carried out in two sessions, first, delivery of material and practice of making charcoal briquettes starting from carbonization of sago bark, forming of charcoal briquettes and second, burning of the charcoal briquettes. The community was involved in the practice of making sago bark charcoal briquettes in order to raise their appreciations and increase their understanding of producing charcoal briquettes from sago bark.

Abstract

Sago waste is a lignocellulose material that has potential as raw material for charcoal briquettes because of its abundance. This study aims to determine the quality of sago waste charcoal briquettes and determine the effect of sago flour adhesive concentration and the effect of pressure on the quality of sago bark charcoal briquettes based on SNI 01-6235-2000. The study used a Factorial Group Randomized Design with two treatment factors and three repeats for each treatment. The first factor is the concentration of the adhesive (A) and the second factor is pressure (B). The parameters observed are moisture content, flying substance content, ash content, bound carbon content, density and calorific value. The results showed that adhesive concentration and pressure factors had a very real effect on water content, ash content, bound carbon content, flying substance content and calorific value while pressure factors had a real effect on ash content and density. Based on research, ash content, density and calorific value meet SNI standards while water content, flying substance content and bound carbon content do not meet the standards. The best treatment based on calorific value is an adhesive concentration of 5% with a pressure of 1 ton (A1B1).Keywords: Biomass, charcoal briquettes, quality, sago, Waste AbstrakLimbah sagu adalah bahan berlignoselulosa yang berpotensi sebagai bahan baku briket arang karena kelimpahannya. Penelitian ini bertujuan untuk mengetahui kualitas dari briket arang limbah sagu serta mengetahui pengaruh konsentrasi perekat tepung sagu dan pengaruh tekanan terhadap kualitas briket arang kulit batang sagu berdasarkan SNI 01-6235-2000. Penelitian menggunakan Rancangan Acak Kelompok Faktorial dengan dua faktor perlakuan dan tiga ulangan untuk tiap perlakuan. Faktor pertama adalah konsentrasi perekat (A) dan faktor kedua adalah tekanan (B). Parameter yang diamati adalah kadar air, kadar zat terbang, kadar abu, kadar karbon terikat, kerapatan dan nilai kalor. Hasil penelitian menunjukkan faktor konsentrasi perekat dan tekanan berpengaruh sangat nyata terhadap kadar air, kadar abu, kadar karbon terikat, kadar zat terbang dan nilai kalor sedangkan faktor tekanan berpengaruh nyata terhadap kadar abu dan kerapatan. Berdasarkan penelitian kadar abu, kerapatan dan nilai kalor memenuhi standar SNI sedangkan kadar air, kadar zat terbang dan kadar karbon terikat tidak memenuhi standar. Perlakuan terbaik berdasarkan nilai kalor adalah konsentrasi perekat 5% dengan tekanan 1 ton (A1B1).Kata kunci: biomassa, briket arang, kualitas, sagu, Limbah
