Abstract

The Lapindo mudflow disaster in East Java Province, or also known as LUSI (LUmpur “mud”-SIdoarjo) has become spectacular longest ongoing disaster in recent memory since 2006. The utilization of volcanic Lapindo mud could be the promising solution to prevent further environmental damage. The chemical composition of Lapindo mud contained of 44.1% SiO2, 23.7% Fe2O3, 13% Al2O3, 7.02% CaO, 5.35% MoO3, 2.53% K2O, 1.84% TiO2 and 0.7% Na2O. Aluminium sulfate (Al2(SO4)3) or “alum” have been widely used as coagulation compound in water treatment, paper and textiles industry. Aluminium sulfate can be synthesized from aluminium oxide (Al2O3) from Lapindo mud with acidic solutions (H2SO4). The aim of this work was to synthesize aluminum sulfate from Lapindo mud by using extraction process. The impact of H2SO4 concentration and heating time to the production of aluminium sulfate have been investigated. The results showed that the aluminium sulfate can be synthesized from Lapindo mud by using H2SO4. Based on XRF analysis, the variation of heating time and H2SO4 concentration affect the aluminium sulfate conversion. The increasing of heating time and H2SO4 concentration directly enhance the conversion until reach the optimum condition. The optimum condition for aluminium sulfate synthesis from Lapindo mud (75.78% conversion) was found to be 90 min for heating time with H2SO4 concentration of 80%

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

The preparation of compost from brem waste has been carried out with the aim of utilizing brem waste into more useful materials. In this work, brem waste was collected from UD.Tongkat Mas, Madiun, East Java. Brem waste compost was processed by aerobic method by adding eggshell powder and M-Bio activator. The M-Bio activator solution that was added was varied with the volume of the solution, i.e., 50, 75, 100, 125 and 150ml. Here, we gave the sample nomenclature of CM50, CM75, CM100, CM125, and CM150, respectively, with the numbers on the back side indicating the volume of M-Bio activator added. Observations on brem compost were carried out for 10 days. Every 2 days interval, measurements of the C/N ratio were carried out on the compost. The manufacture of compost has been successfully made (based on SNI Standard 19-7030-2004) and has the best results by adding 100 ml of M-Bio activator (CM100) with a composting time of 10 days, with a C/N ratio of 11.42, and has no odor.

Abstract

The simple organic waste processing in this journal is a follow-up to the previous activities. By using a concise method that did not take up land, the people of Gebang Putih Village have been able to process simple organic waste into ready-to-use compost. The method used in making ready-to-use compost was to stack brown and green waste in layers and then doused it with two variations of bio-activators, i.e., leri water (rice washing water) and EM4. After the 18th day, the resulting fertilizer showed dry characteristics, odorless, and had a neutral pH. An interesting result in this study was that the compost with the addition of leri water (pH=7) began to decompose on the 9th day. However, in the compost with the addition of EM4, on the 6th day, the compost had decomposed evenly. However, the final results of the compost produced proved that leri water was quite effective as an alternative bio-activator, a substitute for EM4.

Abstract

Training on Utilization of Soybean Husk into Biscuits to Improve Skills of Tempeh Craftsmen Parerejo Village, Pasuruan. Soybean husk from tempeh processing waste has the potential to be developed because the protein content (17.98%), crude fiber (24.84%), and energy (2898 kcal/kg) were quite high but have not been utilized optimally. This activity aimed to provide knowledge on processing soybean husks into flour and their application for making biscuits. The activity was carried out in Belimbing Hamlet, Parerejo Village, Purwodadi District, Pasuruan Regency. The community service method is participatory counseling, where tempeh craftsmen are directly involved in socialization and counseling. Stages of activities include coordination with community leaders and the head of the tempeh association as partners; socialization of the implementation of activities; counseling about the benefits of soybean husk and its application to food products; training on making soybean husk flour followed by making biscuits from the resulting flour. The results of the activity showed that before the activity, 11% of tempeh craftsmen knew that soybean skin could be used as a biscuit product, and 89% did not know it. After the activity, 95% of the tempeh craftsmen know how to process soybean husk into flour and its application in making biscuits.
