Abstract

Indonesia is a country with thousands of islands inhabited by flora and fauna, with these conditions, many organisms such as snails are found. Snails are often considered pests by vegetable farmers. Snails contain amino acids, nitrogen, phosphorus, potassium, and protein that can help increase plant growth and development. The purpose of this study was to utilize snails as liquid organic fertilizer, to find out the process of making liquid organic fertilizer from snails, to find out the differences in the content of liquid organic fertilizer from the three samples, to find out the comparison of growth in eggplant as a test medium, and to find out the effect of the comparison of molasses and snails. The research methods include preparation of raw materials, boiling and crushing snails, mixing materials, and the fermentation process. After that, the fertilizer from the study was analyzed to determine the content of N, P, K. The results showed that for the analysis of NPK content obtained in a sample of 100 grams of snails, the N content value was 0.028%, P 2 O 5 0.016%, K 2 O 0.003%. In a sample of 300 grams of snails, the N content value is 0.041%, P 2 O 5 0.043%, K 2 O 0.050%. Comparative analysis of purple eggplant plants given snail POC and not given snail POC can be seen the difference in stem height and leaf width. In sample 1 which was not given snail POC, the stem height was 9 cm and the leaf width was 5.4 cm, sample 2 with 100 grams of snails had a stem height of 11.2 cm and a leaf width of 7.1 cm, in sample 3 with 300 grams of snails had a stem height of 12.3 cm and a leaf width of 7.7 cm, while in sample 4 with 500 grams of snails which had a stem height of 15.4 cm and a leaf width of 9.5 cm. This shows that sample 4 with 500 grams of snails has a very good growth rate. The differences in the research test results are due to differences in the dosage or variation and weight of snails and molasses given to each sample.

Abstract

Sweet potato (Ipomea Babatas, L.) is a tuber plant that contains carbohydrates, calcium, and starch. Besides being consumed as food, sweet potato can be used as a raw material for making glucose syrup. The study aimed to investigate the effect of hydrolysis time and HCl volume on glucose production. The starch was extracted from sweet potatoes then deposited for an hour. The glucose syrup production was carried out by acid hydrolysis method at 100°C. The results showed that the highest glucose content of 62.76% was obtained at 30 minutes hydrolysis time and 15 ml HCl volume. The smallest glucose content is obtained at the longest hydrolysis time. The greater the volume of HCl, the smaller the glucose content.

Abstract

Sonochemistry has many applications in biomedical engineering owing to its ability to break chemical bonds. It can also be used to facilitate the preparation of aqueous quantum dots (QDs) dispersions during microemulsion formati on. Cavitation, bubble growth and collapse during sonication facilitate the formation of microemulsions between a solvent and water. Sonication was employed in this study to prepare aqueous copper indium sulfide colloidal zinc sulfide (CuInS2/ZnS) QD dispersions using different solvent systems. The resultant QDs were characterized by UV-vis absorption, photoluminescence, and dynamic light scattering. Hexane was determined to be the best solvent for the preparation of QD dispersions with the resultant QDs (30 nm in diameter) retaining their chemical integrity and >30% of their quantum yield. CuInS2/ZnS QD dispersions in water can be directly prepared without any non-polar solvent and it has shown high quantum yield. Further, it was also shown that less-toxic, which is efficient in labeling tumor cells derived from human liver cancer (HepG2). It’s evident that, sonication was found to be an efficient alternative approach for preparing aqueous QD dispersions without the need for surface modification, or the use of non-polar solvents during microemulsion formation.

Abstract

Consumption of noodles in the world is always increasing. Noodles made from wheat flour are unhealthy because they cause diabetes, so alternative noodles are needed, such as modified cassava flour and seaweed. Modification cassava is used because it does not contain gluten and seaweed has nutritional value to make healthy, low-calorie noodles. The purpose of this study was to determine the temperature and time of the drying parameters of seaweed noodles. The drying method uses an oven with variable temperature (60, 70, 80, and 90 ) and drying time (2, 4, 6, 8, and 10 hours). The results of the study obtained optimal water content at 60  with 6 hours of 11.75%. The drying kinetics evaluated by logarithmic equation, optimal drying constant value at 80  of 0.67 h-1 with R2 0.9391. Effective moisture diffusivity (Deff) maximum evaluated by second Fick law obtained 9.35×107 m2/sec at temperature 90  with R2=0.9227. The proximate value of ash content is 12.11%, protein is 9.46%, lipid is 0.10%, and carbohydrates is 65.08%.

Abstract

Abstract: Biogas promises bioenergy to be developed as a renewable fuel to reduce the fossil energy crisis. Biogas raw material can be derived from tofu liquid waste. Biogas is processed by anaerobic digestion. This study aimed to develop a simulation of the kinetic model variations of biogas production from tofu liquid waste. The results showed that the ascending limb of the exponential equation had a greater coefficient (R2 = 1) than the ascending limb of the linear equation (R2 = 0.9574). The descending limb of the linear equation had a better coefficient (R2 = 0.9574) than the descending limb of the exponential equation (R2 = 0.95). The Gaussian model had the greatest R2 of 0.9937. Logistic growth had the greatest coefficient (R2 = 0.9951) compared to modified Gompertz (R2 = 0.9817) and exponential rise to maximum (R2 = 0.9852) in the simulation of cumulative biogas production. The fit model for kinetic biogas production from tofu liquid waste is Gaussian Model.Abstrak: Biogas merupakan salah satu bioenergi yang menjanjikan untuk dikembangkan dalam mengurangi krisis energi fosil.

Abstract

Abstract: Spirulina platensis Residue (SPR) is obtained from the solid residue of Spirulina platensis extraction, which has high carbohydrate and protein content. Pyrolysis technology will convert SPR into a bio-oil, water phase, char, and gas (CO, CO2, H2, CH4) product with the potential as an environmentally friendly and sustainable fuel. This study aims to obtain data on the optimum conditions and product yield composition of SPR catalytic pyrolysis using the in-situ method.  Pyrolysis occurs in a fixed-bed reactor with SPR 50 g feed and Fe3O4 catalyst (2.5 g and 5 g) at temperature variations of 300-600 °C with an average heating rate of 14.07 °C/min. The higher the pyrolysis temperature, the more bio-oil yield, the optimum at a temperature of 500 ⁰C. The use of 2.5 and 5-gram catalysts obtained bio-oil yields of 25.01 and 17.67 %. The yield of biochar will be lower with increasing pyrolysis temperature. The optimum condition for the gas production was achieved at 300 °C, using a catalyst of 2.5 and 5 grams, the yield of gas was 23.59, and 19.74 %. Moreover, the smaller the specific gravity and the higher the bio-oils pH, the better it is as a vehicle fuel.Abstrak: Spirulina platensis Residu (SPR) diperoleh dari residu padat ekstraksi Spirulina platensis yang memiliki kandungan karbohidrat dan protein tinggi. Teknologi pirolisis akan mengubah SPR menjadi produk bio-oil yang berpotensi sebagai bahan bakar ramah lingkungan dan berkelanjutan. Penelitian ini bertujuan untuk mendapatkan data kondisi optimum dan komposisi yield produk dari pirolisis katalitik SPR dengan metode in-situ. Pirolisis SPR akan menghasilkan produk berupa bio-oil, water phase, char dan gas (CO, CO2, H2, CH4). Pirolisis berlangsung dalam reaktor fixed-bed dengan umpan SPR 50 g serta katalis Fe3O4 (2.5 g dan  5 g)  pada variasi suhu 300-600°C dengan heating rate rata-rata 14,07 °C/min. Semakin tinggi suhu pirolisis semakin banyak yield bio-oil, optimum pada suhu 500 ⁰C. Pemakaian katalis 2,5 dan 5 gram diperoleh yield bio-oil sebanyak 25,01 dan 17,67 %. Yield biochar akan semakin rendah dengan kenaikan suhu pirolisis. Kondisi optimum produk gas dicapai pada 300 °C dengan katalis 2,5 dan 5 gram diperoleh yield gas sebesar 23,59, dan 19,74 %. Hal tersebut mengakibatkan, semakin kecil berat jenis dan semakin tinggi pH bio-oil maka semakin baik sebagai bahan bakar kendaraan.
