Abstract

Biskuit merupakan salah satu makanan olahan yang cukup populer dan banyak dikonsumsi oleh semua kalangan usia. Bahan utama dalam pengolahan biskuit umumnya adalah tepung terigu. Tepung terigu banyak digunakan untuk membuat adonan karena mengandung protein gluten yang dapat memperbaiki tekstur adonan. Akan tetapi, protein gluten dalam terigu tidak dapat dikonsumsi oleh penderita gluten intoleran, khususnya pada penyandang celiac disease dan Autism Spectrum Disorder (ASD) karena tubuh anak yang menderita autisme memiliki masalah dalam memecah protein gluten. Salah satu alternatif yang dapat dilakukan yaitu dengan membuat biskuit bebas gluten menggunakan tepung mocaf. Sosialisasi biskuit bebas gluten di UD Sofia Cookies diharapkan dapat memberikan wawasan mengenai biskuit non-terigu yang baik untuk kesehatan dan sangat berpotensi untuk diproduksi seiring dengan meningkatnya isu autisme di Indonesia. Metode yang dilakukan yaitu dengan penyampaian materi yang dibawakan oleh pemateri. Kegiatan sosialisasi berlangsung dengan cukup baik, dilihat dari antusiasme peserta yang cukup tinggi selama kegiatan.

Abstract

Indonesia is the country with the largest muslim population in the world, so it is a domestic market for halal products. The Micro, Small, and Medium Enterprises (MSMEs) sector is the driving agent of the halal value chain. UD Sofia Cookies is one of the MSMEs in Surabaya that produces various pastries or cookies. UD Sofia Cookies already has a PIRT distribution permit and is currently making efforts to register halal certification. One of the criteria for the halal assurance system (SJH) from LPPOM MUI is the traceability system. Traceability is an aspect needed to ensure the halalness of halal product materials starting from the purchase of raw materials, production processes, to logistics and product distribution. Traceability can increase consumer confidence as well as a requirement for food safety, health, and authenticity of food products. UD Sofia cookies have not implemented a halal traceability system, so they require socialization and assistance in implementing a halal traceability system. The results of socialization and assistance show that UD Sofia Cookies employees have been able to implement a halal traceability system. So that UD Sofia Cookies can proceed to the next stage to register a halal certificate.

Abstract

The electrolyte or ion conductor acts as a bridge to transfer the ions the electrodes generate. In general, electrolytes are in the form of liquids. However, liquid electrolytes have drawbacks, including needing to be more practical and leaking quickly. Therefore, people switch to solid matrix electrolytes as battery electrolytes. An ideal solid electrolyte membrane must have chemical stability, thermal stability, high ionic conductivity, high flexibility, low cost, and abundant material availability. Lithium extraction from used batteries using Deep Eutectic Solvent (DES) was found to be an intelligent solvent. Mixing the method with lithium salt on a chitosan membrane can increase conductivity. This study aims to determine the lowest resistance value and highest conductivity of solid polymer electrolytes using Li2CO3 from used batteries. After separating the Lithium-Cobalt component from the used battery, it was extracted with deep DES solvent and precipitated using Na2CO3 to produce the Li2CO3 compound. Polymer electrolyte was synthesized by mixing polyvinyl alcohol and adding 0.2 grams, 0.4 grams, 0.6 grams, 0.8 grams, and 1 gram of chitosan. Li2CO3 variables are 0.2 grams, 0.4 grams, 0.6 grams, 0.8 grams, and 1 gram. The results showed that the higher content of chitosan and Li2CO3 led to an increase in ionic conductivity. These results concluded that the best solid electrolyte membrane was obtained with a variation ratio of 0.2 grams of chitosan with the addition of 1 gram of Li2CO3.

Abstract

Geothermal sludge is a waste product from geothermal where it contains SiO2 which can be used as fertilizer. In this study, the making of silica ammonium fertilizer was carried out by taking salicy acid from geothermal sludge by extracting and adding resin which was then modified with NH4OH addition. Extraction was done using 1000 ml of KOH 1 N to dissolve 60 grams of Geothermal Sludge. Resins are added with variations in resin weight, namely, 5, 10, 20, 30, and 40 grams. NH4OH was added with variations in concentrations namely 3, 6, 9, 12 and 15% with a ratio of filtrate and NH4OH solution of 1: 1. The resulting ammonium silica inorganic liquid fertilizer products were analyzed for free silica and ammonia levels. The results of this study indicate that the levels of free silica and ammonia are influenced by the weight of the resin used and the concentration of ammonium hydroxide mixed. From the results of the research, it was found that inorganic silica liquid fertilizer with the highest SiO2 content in ammonium silica liquid fertilizer occurred when adding 20 grams of resin with the addition of NH4OH with a concentration of 15% which was 1,831.87 mg / L while the highest NH3 content in fertilizer liquid ammonium silica occurs when adding 40 grams of resin with the addition of NH4OH with a concentration of 15% which is equal to 252,312.80 mg / L.

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 government has taken energy deflation seriously and is trying to find solutions by implementing energy efficiency and utilizing renewable energy sources. That action also supports the procedure to save the world from the ongoing climate crisis. One of Indonesia’s potential renewable energy sources is biomass, which can be in the form of plantation waste such as teak branches. Based on the analysis results, charcoal made from teak branches had a carbon content about 62.5968%, so it was pretty potential to be used as raw material for bio-briquettes. In this research, bio-briquette from teak branches' charcoal using tapioca binder has been successfully carried out. The manufacture of bio-briquettes was studied by observing the effect of the size parameters of teak charcoal and binder ratio on the heating value and water content of briquettes. The analysis results showed that these two parameters significantly affected the quality of teak branches' bio-briquette. In the ranking, the particle size was much more significant in influencing the calorific value of bio-briquettes, while the binder ratio had more influence on the water content value. The obtained bio-briquettes' calorific value and water content have met the established standards.
