Abstract

The high value of COD (Chemical Oxygen Demand) is one of the indicators of the burden of organic substance pollution in the wastewater food flavoring industry. COD values can be lowered by converting to biogas. In this study biogas was made through a two-stage fermentation system. At the first stage organic material is conditioned in an acidic state (pH = 4) with variable fermentation time: 2 days, 4 days, 6 days and 8 days. Then at each time fermented for 18 days at second stages. As a result, the amount of biogas volume produced is the same, namely: 7,5 L. However, the most amount of methane is produced at the time of fermentation phase one for 2 days, namely: 83%. While the lowest value is produced at the time of fermentation phase one for 8 days, namely: 70%. At the time of fermentation phase one for 8 days produced the highest hydrogen composition, namely: 9,023 %. The composition of methane at stage one for 4 days produces a higher value, namely: 81.431% compared to the single stage fermentation system, namely: 78.9 %.

Abstract

Fruit peel waste is a big problem nowadays because the production of waste is getting bigger as the population grows. On the other hand, fruit peel waste contains elements of N, P, K which can be used to make organic fertilizer. This research was conducted by mixing water, banana peel waste and EM-4 bacteria with the fixed variables used were banana peel waste and the amoufant of EM-4 bacterial bio activator while the independent variables used in this study were the fermentation time for (2 days, 4 days and 6 days). days), with variations in initial pH (4 and 5). Testing of organic fertilizers was carried out based on the standard method of SNI 2803. Testing of nitrogen content using the Kjeldahl method, phosphorus levels as P2O5 using a UV-Vis Spectrophotometer, potassium as K2O using an Atomic Absorption Spectrophotometer (AAS) instrument. The results showed that the best level of nitrogen was 1,297.43 ppm and the best level of phosphorus was 86 ppm which was produced on the second day of fermentation with a variation of initial pH 4. While the best potassium level was obtained by a variation of initial pH 5 at a fermentation time of 6 days, namely 11,735.6 ppm. Based on the analysis of the levels of N, P, K that was carried out, the organic fertilizer produced did not meet the SNI specifications.

Abstract

ABSTRAKSaat ini 85% dari kebutuhan energi dunia berasal dari bahan bakar minyak. Indonesia berupaya mengurangi ketergantungan pada bahan bakar minyak. Salah satu sumber energi alternatif yang dapat mensubsitusi transportasi minyak mentah diperoleh dari biomassa berupa bahan bakar bioetanol. Biomassa termasuk beras dimanfaatkan untuk pengembangan bioetanol menggantikan bahan bakar minyak. Karbohidrat merupakan komponen utama beras yang terdiri dari 85–90% pati. Air cucian beras yang mengandung karbohidrat dapat diubah menjadi etanol. Penelitian ini bertujuan untuk mengetahui waktu fermentasi terbaik dalam produksi bioetanol dari air cucian beras dengan menggunakan enzim glukoamilase dan ragi. Pembuatan bioetanol melalui tahap persiapan, hidrolisa air cucian beras, pemeriksaan kadar glukosa, fermentasi, distilasi dan analisa hasil. Variabel yang digunakan adalah waktu fermentasi (3, 4, 5, 6, dan 7 hari), dan volume enzim glukoamilase  (0.5, 1.5, dan 3.0 ml). Hasil penelitian diperoleh  densitas bioetanol optimum sebesar 0.998 g.ml-1 dengan enzim glukoamilase  0.5 ml. Kadar glukosa sesudah inversi tertinggi sebesar 4.217%, dan kadar etanol tertinggi 19.387% dihasilkan dengan dosis enzim glukoamilase 3.0 ml dalam waktu fermentasi selama lima hari.Kata kunci: air cucian beras, bioetanol, enzim glucoamilase, fermentasi, ragi ABSTRACTCurrently, 85% of the world's energy needs come from fuel oil. Indonesia overcomes dependence on fuel oil. One of the alternative energy sources that can substitute crude oil transportation is obtained from biomass in the form of bioethanol fuel. Biomass, including rice, is used for the development of bioethanol to replace fuel oil. Carbohydrates are the main component of rice which consists of 85–90% starch. Rice washing water which contains carbohydrates can be converted into ethanol. This study’s aim was to have the best fermentation time in bioethanol production from rice washing water using glucoamylase enzymes and yeast. Bioethanol production goes through the preparation stage, hydrolysis of rice washing water, checking glucose levels, fermentation, distillation, and yield analysis. The variables were fermentation time (3, 4, 5, 6, and 7 days), and the volume of the glucoamylase enzyme (0.5, 1.5, and 3.0 ml). The results showed that the optimum bioethanol density was 0.998 g.ml-1 with 0.5 ml glucoamylase enzyme. The highest glucose level after inversion was 4.217%, and the highest ethanol content was 19.387%, which was produced with 3.0 ml glucoamylase enzyme dosage in five days of fermentation.Keywords: rice washing water, bioethanol, glucoamylase enzyme, fermentation, yeast

Abstract

Bahan bakar merupakan kebutuhan pokok bagi manusia, Namun ketersedian bahan bakar fosil semakin lama semakin berkurang. Biogas merupakan solusi alternatif untuk memenuhi kebutuhan manusia akan bahan bakar. Tujuan penelitian ini adalah mengetahui pengaruh penambahan Effektive Mikroorganisme 4 (EM-4)  terhadap kualitas biogas yang dihasilkan dari limbah industri makan. Proses pembuatan biogas dilakukan secara batch di dalam digester anaerobic berukuran 2,5 Liter pada suhu ruangan. Dua liter campuran yang terdiri dari limbah, air dan  Effektive Mikroorganisme 4 (EM-4)  dimasukkan ke dalam digester anaerobic, dimana pH, COD, dan volume gas diamati setiap hari secara periodik. Pada penelitian ini Nilai pH yang dihasilkan berkisar antara 6 - 7,2. Nilai COD menurun dengan meningkatnya penambahan EM-4. Volume biogas yang dihasilkan semakin besar dengan meningkatnya penambahan EM-4.  Volume biogas Terbesar yang dihasilkan sebesar 9,7 L dengan konsentrasi gas metana ( 84,376 %), karbon dioksida (11,679 %), nitrogen (3,945%).     Keywords : Methane, Biogas, Digester, Anaerobic, EM-4.

Abstract

The use of synthetic coatings as Food Additives consumed in the long term can damage human health. These horrible effects have paved the way for the development of edible films and natural edible coatings. One of the edible film ingredients is scorched rice which can be used as a coating in fruit preservation. However, the use of this edible film on food ingredients has some problems, especially its mechanical properties which tend to be fragile (not flexible). This article examines the mechanical characteristics of scorched rice with variations in the concentration of glycerol and carrageenan. Based on these results, it was concluded that the higher the volume of glycerol used, the percent elongation increased. The greatest elongation was obtained in the ratio of 3 g of carrageenan with 8 ml of glycerol. However, the addition of glycerol volume causes the biodegradable plastic to tear more easily. The greatest tensile strength value was obtained with a ratio of 5 g of carrageenan and 4 ml of glycerol. The edible film can prevent the spoilage of apples tested for 10 days.

Abstract

Indonesia has various sources of graphite in large quantities. One of them is palm oil waste. Palm oil is a horticultural crop that acts as the largest non-oil and gas foreign exchange contributor in Indonesia. This study aims to synthesize graphite from oil palm trunks with a catalyst through the pyrolysis method. This is an experimental research which eventually generated qualitative data to be analyzed. Oil palm trunks are dried in the sun, then crushed into powder with a grinder and sieved to 200 mesh. Graphite was synthesized using a carbonization step at 500°C. Impregnation using 3M ferric chloride (FeCl3), with a concentration variation of 10% and 30%. Further activation at a temperature of 900°C for 3 hours. The results synthesis of graphite powder were washed with hydrochloric acid (HCl) and distilled water repeatedly to obtain relatively pure graphite. Graphite characterization includes Fourier Transform Infrared Spectroscopy (FTIR). The results of FTIR analysis showed that graphite contains functional groups O–H, C–H, C–O, C?C, and C=C.
