Abstract

Potassium-Silica Humate Composite Gel or K-Si-Humate Composite Gel is a combined material of Potassium and Silica Humate derived from the extraction of raw materials for geothermal sludge and peat soil. This material is a multipurpose material, which can be used to improve soil aeration and as a fertilizer that can fertilize the soil because it contains humic acid. The purpose of this study was to examine the effect of cellulose content on the characteristics of the Potassium Silica-Humate composite gel. The manufacture of K-Si-Humate Composite Gel in this research by extracting potassium and silica from geothermal sludge and humic acid from peat soil, then the process of filtration and gel formation. The variable used is the addition of carboxymethyl cellulose content, namely Carboxy Methyl Cellulose (CMC). The best results from this study showed that with the addition of CMC, the highest silica content was 15.85%, and the highest potassium content was 89.88%.

Abstract

Food safety issues are still an important issue in the food sector in Indonesia and need special attention in food control programs. Therefore, it is necessary to improve the quality and safety of the products produced by developing a food safety assurance system in the form of a Hazard Analysis and Critical Control Point (HACCP). HACCP is a food safety assurance system in the form of a systematic approach to identifying hazards and put in place control systems to prevent them. One of the important reasons for implementing the HACCP system in the food industry is because the ingredients used during the production process have the possibility of contamination that can harm consumers. Cu's Chicken Crispy is a small industry that produces food. His party wants to implement a Hazard Analysis Critical Control Point (HACCP) management system to improve product quality assurance. This study aims to identify hazards related to the production aspects (raw materials, packaging, and processes) of Cu’s Chicken Crispy and determine the CCP related to the production of Cu’s Chicken Crispy. This study conducted a direct interview with the owner and made a direct visit to Mrs. Cu's food stall. In this study, it was found that there is a significant potential danger to chicken meat raw materials. At the stage of the production process that falls into the category of salting, draining and packaging refer to CCP.

Abstract

Food is a basic human need. so that food hygiene needs to be considered so that it does not have a negative impact on human health. Many kinds of food are sold outside, such as regional food. To find out the critical point of food, it is necessary to study literature, observations and interviews with small industries. The purpose of this reaserch is to identify the preparation of HACCP (Hazard Analysis Critical Control Point) application on small industries, which is Serabi solo shop. From the observations made, a critical point hazard analysis will be carried out starting from the preparation of the Serabi solo material to packaging. The results show that the Serabi solo shop had 34.78% Prerequisite Programs. So the Serabi solo shop need more improvement to meet the standards of food safety management.

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

Hydroxyapatite is a calcium phosphate compound that is the main inorganic component of bones and teeth. Hydroxyapatite has a main role in the medical world because of its identical chemical properties and structure to human bone. Kupang shells have a high CaCO3 content of 95-99% by weight. So this concurrence, the mussel shells are to be used as good as an ingredient for making Hydroxyapatite. The variables used in this research are Temperature of the Furnace and Phosphoric Acid Concentration, which were 700ºC, 750 ºC, 800 ºC, 850 ºC, 900 ºC and Phosphate Acid Concentrations 0.4M, 0.6M, 0.8M, 1M, and 1.2M. The product results were tested with XRD analysis to determine the crystal structure contained in the product and the level of Hydroxyapatite in the product. The best research results in this study at a temperature of 900ºC at a concentration of 1.2M phosphoric acid with a Hydroxyapatite content of 100% with lattice parameters an (Aº)=b (Aº) = 9..422, c (Aº)=6.8835, and gamma = 120º.

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

Program Bina Desa Kalipucang menggunakan limbah batang pisang untuk membuat biobriket. Batang pisang limbah dapat digunakan sebagai sumber pati (5-10%), 20% hemiselulosa, 5% kandungan lignin, dan selulosa (±63%) yang diubah menjadi karbon selama proses pembakaran. Dengan demikian, pisang limbah dapat dicetak menjadi briket. Dengan jumlah batang pisang yang sangat sedikit digunakan, limbah pisang dapat digunakan sebagai pengganti untuk membuat briket. Kegiatan bina desa ini menggunakan limbah batang pisang yang diproses menjadi produk bernilai tinggi. Briket batang pisang ini dibuat melalui proses karbonisasi dengan lubang pada kaleng bekas. Hasil dari kegiatan bina desa ini adalah bahwa program kerja ini memberi tahu warga desa tentang cara mengolah limbah batang pisang menjadi briket dan memberikan sosialisasi tentang peluang bisnis untuk meningkatkan pendapatan desa.

Abstract

Micro Small to Medium Enterprises (MSMEs) are one of the economic pillars of society in Indonesia. Most people choose MSMEs as their livelihood because of the relatively small capital and fast results. In Krembung Village, many MSMEs have been established in various fields, including culinary, fashion, services, and many more. However, most of the culinary sector still uses conventional marketing. This marketing is considered less effective in this digital era. The method of non KKN T MBKM in this service is by observing MSMEs, creating Instagram accounts and banners, as well as digital marketing training. The result of implementing this service is that culinary MSMEs understand digital marketing and promotions and get an increase in sales after implementing this digitalization.
