Abstract

The prawn cracker industry is one of the most common types of food industry in Indonesia. The existence of this industry has a positive impact in maintaining and improving the Indonesian economy, but it can also have a negative impact on the environment in particular, because this industry produces wastewater which can have a negative impact on the aquatic environment if the wastewater is directly discharged into the river. Based on the results of the analysis of the quality of wastewater from one of the shrimp cracker industries, it is known that wastewater contains Chemical Oxygen Demand (COD) which is 3446 mg/L, Biological Oxygen Demand (BOD) 1118.9 mg/L and acidity (pH) 5.88 – 6.13. Referring to the wastewater quality standards for the shrimp cracker industry, namely COD: 120 mg/L, BOD: 50 mg/L, and acidity pH: 6-9, the shrimp cracker industrial wastewater must be treated first before being channeled into the body. river receiving water. In this study, the treatment process used is an aerobic biological process with a modified contact-stabilization method. This method is the development of the contact-stabilization method, where in this modified method the wastewater from the treatment is recycled to the stabilization tank and together with the bacteria is transferred to the contact tank. Variations carried out in this study are the incoming wastewater flow rate (liters/hour): 4,5 ; 5.5; 6.5 ; 7.5 and 8.5 and flow rate of recycled water from treatment to stabilization tank (%) : 10 ; 20 ; 30 of the incoming wastewater flow rate. The best results were obtained at the wastewater flow rate of 5.5 liters/hour and the recycled water flow rate from the treatment to the stabilization tank 20% with a decrease in the COD value of 97.3% and BOD of 98.4% and the pH of the treated water 6.9.©2021 JNSMR UIN Walisongo.

Abstract

Tartaric acid and maleic acid are carboxylic acids that effectively inhibit the growth of struvite crystals and weak organic acids that are friendly environments. The purpose of this study was to determine the effectiveness of inhibition of struvite crystal growth from the effect of adding carboxylic acid (tartaric acid and maleic acid) using batch operation which can be used as a slow-release fertilizer. Struvite is an effective phosphate fertilizer as an alternative source of rock phosphate to maintain agricultural production systems. From the results of the study, tartaric acid was found to be 10,483 mg at a temperature of 40oC with a concentration of 20 ppm and stirrer rotation of 300 rpm which was a better optimum condition to be applied in the struvite fertilizer industry when compared to maleic acid. Characterization of struvite crystals using XRPD Rietveld and SEM-EDX methods.

Abstract

Bio briquette is a briquette based on agricultural waste because it is deliberately made from biomass charcoal. The utilization of agricultural waste such as mushroom planting media to be processed as bio briquette requires a very cheap cost. Bio briquettes that are processed properly and correctly, will produce high-quality briquettes. The purpose of this study was to produce a biobriquette from baglog mushroom waste and to determine the characteristics of the biobriquette. The research material used consisted of 400 grams of mushroom baglog waste and 40 grams of starch as adhesive. The briquette dough is then printed cylindrical. The printed briquettes are then heated at 80°C for 5 hours to reduce the moisture content. The result of smoke test is the smoke will stop in 17 seconds with the color of the smoke is white. The Combustion of speed test, the results obtained are 0,0019 gram/second with an initial sample weight of 2, 4 grams and burning for 20 minutes 35 seconds with a final sample weight of 0,387 grams. The result of ash content is 0.16%. This result is in accordance with the SNI issued by our government. SNI of ash content is max 8 %.

Abstract

This study aims to determine the effect of consumption of lesser yam synbiotic yoghurt on glucose levels and blood lipid profiles of metabolic syndrome rats. Synbiotic yoghurt has positive effect on health such as increasing body immunity, lowering blood glucose and cholesterol levels. In this study, lesser yam synbiotic yoghurt was made from cow's milk and lesser yam extract with (1:1) proportion, sugar, skim milk and starter of lactic acid bacteria and then followed by bioassay test using experimental rats. The results showed that lesser yam synbiotic yoghurt can reduce glucose levels and improve the blood lipid profile of rats. The best treatment is to give 4 ml of synbiotic yoghurt per day which can reduce glucose levels and total blood cholesterol of metabolic syndrome rats. It can be concluded that lesser yam synbiotic yoghurt which had high levels of dietary fiber and inulin, had hypoglycemic and hypocholesterolemic effect.

Abstract

Bioethanol is an alternative energy source that can be used to reduce dependence on fossil fuels. This study aims to produce bioethanol from pineapple peel waste using Clostridium acetobutylicum bacteria with initial pre-treatment to separate cellulose and lignin. The research methods include raw material preparation, delignification, hydrolysis, and fermentation. The results show that pre-treatment with NaOH solution successfully reduces lignin content in pineapple peels, while hydrolysis using HCl solution increases glucose content. Fermentation with variations in starter concentration and nutrient type resulted in the highest bioethanol content of 4% with the use of urea nutrient and 7% starter concentration. GC-FID analysis indicates that besides ethanol, methanol is also detected as a by-product. In conclusion, Clostridium acetobutylicum bacteria can be used to produce bioethanol from pineapple peel waste, with the concentration of starter and nutrient type influencing the ethanol content produced.

Abstract

Tujuan dari penelitian ini adalah untuk mengidentifikasi sifat katalis besi (Fe) pendukung ZSM-5 yang disintesis dengan berbagai metode yaitu impregnasi (IG) dan solid state ion exchange (SSIE) dan variasi prekursor Na-ZSM-5, NH4-ZSM-5 dan H-ZSM-5. Bubuk katalis yang diperoleh dikarakterisasi dengan analisis dasar x-ray diffraction (XRD) dan Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX). Hasil XRD memperlihatkan adanya perbedaan precursor menghasilkan perbedaan kristalinitas tetapi tidak menunjukkan pergeseran puncak. Puncak difraksi yang dihasilkan sesuai dengan standar ZSM-5 pada 2θ = 7,8°, 8,7°, 23,0°, & 24,0°. Penerapan perbedaan metode sintesis menghasilkan pergeseran puncak difraksi yang menunjukkan adanya perubahan ukuran partikel. Hasil identifikasi secara mikroskopis menunjukkan ZSM-5 termodifikasi logam Fe pada kedua metode terdapat aglomerasi partikel berbentuk struktur prismatik dan memiliki struktur yang lebih rapat dengan ukuran panjang rata-rata yang berbeda yaitu pada Fe-Na-ZSM5 (IG) sebesar 968nm, dan Fe-NH4-ZSM-5 (IG) sebesar 799nm. Hasil identifikasi distribusi unsur Fe pada pendukung ZSM-5 menunjukkan bahwa prekursor dengan kation NH4 pada ZSM-5 memiliki kandungan Si lebih tinggi dibandingkan dengan ZSM-5 berkation Na. Keberadaan logam Fe pada ZSM-5 menunjukkan persentase yang sangat rendah yaitu 0,26% pada Na-ZSM-5 (IG), 0,27% pada NH4-ZSM-5 (IG), 1,21% pada Na-ZSM-5 (SI), 0,81% pada NH4-ZSM-5 (SI). Hasil yang diperoleh dapat menjadi informasi dasar dalam penentuan jenis prekursor awal antara Na-ZSM-5, NH4-ZSM-5 dan H-ZSM-5 serta metode preparasi yang tepat untuk menghasilkan interkoneksi dan penyebaran logam merata dalam mencapai material Fe-ZSM-5. DOI : https://doi.org/10.33005/jurnal_tekkim.v17i2.3784
