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.

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

Meanwhile, Semi-Refined Carrageenan (SRC) could be combined with starch as the base material for edible film fabrication to increase its tensile strength. This study aimed to identify edible film by synthesizing SRC and mango seed starch with plasticizer sorbitol, which could be safe for consumption in food packaging. The process of making edible film consists of three steps: extracting Eucheuma cottonii seaweed, making starch from mango seeds, and making edible film. The method used was the solution casting method, with a ratio of SRC: starch of mango seeds, namely 1: 0; 0.7: 0.3; and 0: 1 (w / w) and sorbitol concentrations of 20, 30, 40, 50, and 60% (w/w). This research shows that increasing sorbitol could decrease the tensile strength but increase the elongation and solubility of the edible film. As well as the combination of SRC and mango seed starch can produce edible films with higher characteristics than edible films based only on SRC or mango seed starch. The results of selecting the best conditions for an edible film based on the Japanese Industrial Standard (JIS) are the concentration ratio of SRC: mango seed starch (0.7: 0.3) and 30% sorbitol concentration with a thickness value of 0.22 mm, tensile strength 4.81 MPa, 28.50% elongation and 68.44% solubility

Abstract

PT. Candi Jaya Amerta is an industry that produces fly ash from coal combustion in boilers and wastewater from its production processes. The utilization of fly ash in this industry has not been well optimized, and the wastewater is characterised by elevated concentrations of organic matter, primarily generated from shrimp cracker production. High organic content in wastewater can lead to environmental pollution. Goal of this research is to determine the effect of sampling time on the reduction of Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels in the wastewater of PT. Candi Jaya Amerta using fly ash adsorbent through a column adsorption process system, employing the Yoon-Nelson, Adam-Bohart, and Thomas approaches. The variables employed in this study are sampling times of 20, 40, 60, 80, and 100 minutes, and adsorbent heights of 9, 13, 17, 21, and 25 cm. The research findings show that the optimal adsorbent height for reducing COD is 21 cm, with a reduction percentage of 88.2705% and a COD adsorption capacity of 7.2593 mg/g at a sampling time of 60 minutes. Meanwhile, the optimal adsorbent height for reducing BOD is 25 cm, with a reduction percentage of 98.1509% and a BOD adsorption capacity of 87.4255 mg/g at a sampling time of 60 minutes.
