Waste from processed household activities that do not experience good management can cause environmental pollution. The rubbish in the form of vegetable and fruit waste still contains waste that can be further processed to be more useful. Liquid organic fertilizer is fertilizer whose basic ingredients come from animals, plants, or both that have undergone a process of fermentation and its final form is liquid. The making of liquid organic fertilizer from javanese goat urine and household organic waste with the addition of EM4 bioactivators (effective microorganisms) aims to determine the effect of fermentation time length, the effect of adding EM4 bioactivators, and the effect of adding the javanese goat urine with household organic waste compared to household organic waste without the addition of javanese goat urine to the pH, N, P, and K contents in liquid organic fertilizer. The results showed that for the analysis of pH obtained in samples of 4.5 to 8.5, while for the analysis of nitrogen, phosphorus, and potassium the best nitrogen (N) content was 2.3672% in 10 mL EM4 samples with a fermentation time of 21 days. The best phosphorus (P) content was 0.6857% in the 15 mL EM4 samples with a fermentation time of 14 days. And the best potassium (K) content was obtained at 1.0559% in the EM4 samples of 10 mL with a fermentation time of 7 days.

The chemical composition of potatoes includes carbohydrates, protein, fiber, vitamins, and minerals. The composition of vitamins and minerals in potatoes is higher than wheat flour. Brownish color in potato flour has reduced consumer's interest, so it needs to be modified to improve the color and physicochemical properties of flour. Researchers are trying to modify the blanching process using hydrogen-rich water. Because hydrogen-rich water has antioxidants that can prevent the browning process (oxidation) potato flour, cheaper, safer, and healthier than chemical compounds. The purpose of this study was to optimize the blanching process for potato flour modification. Variation of the process used is soaking time at 30, 45, 60, 75, and 90 minutes. The optimal results of water content, ash content, reducing sugar content, protein, color, and swelling power were obtained at 75 minutes are 6.7%, 2.68%, 0.26%, 7.1%, 81.17, and 7 g/g. The quality of the modified potato flour met the physicochemical parameters of the flour according to the SNI standard for flour, except ash content. The quality of potato flour produced almost equals as the quality of wheat flour, so it needs to be considered as a substitute for wheat flour and is friendly for diabetics.Keywords: potatoes, modified flour, physicochemical properties, wheat

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.
