PT. Dharmalindo Eka Persada, a foam-based producer, is facing the problem of stockpiling raw materials for aluminum thermal insulation and anti-vibration products due to unstable fluctuations in market demand. This study analyzes the application of the just in time method in companies for inventory cost efficiency. Using a qualitative descriptive approach with interviews, library studies, and inventory reports for 2022, the study found that current inventory control policies are not optimal. In the case of the raw material polyurethane foam eow gray, savings of 55% were achieved with the JIT method, reducing inventory costs from Rp.18,553,771 to Rp.8,297,499. For the raw material polyethylene foam fireretendant, savings of 55% also occurred with inventory costs falling from Rp.43,655,932 to Rp.19,523,526.

SDS Arya Jaya Sentika Tigaraksa merupakan salah satu sekolah dasar swasta yang berada di kecamatan Tigaraksa. Saat penilaian kinerja guru masih dilakukan dengan cara mengisi lembar form dan mengumpulkan dokumen pendukung, yang menyebabkan menumpuknya dokumen pendukung dan sering terjadi dokumen yang hilang, sulit untuk di cari jika diperlukan, maka dari permasalahan diatas dibutuhkan sistem informasi penilaian kinerja guru. Untuk membangun sistem ini menggunakan metode pengembangan agile model, dengan perancangan UML yaitu use case diagram, dan activity diagram. Hasil dari penelitian ini adalah sistem informasi penilaian kinerja guru berbasis web, yang dapat membantu pihak sekolah dalam penilaian kinerja setiap guru yang dapat lebih efektif dan efisien dalam menilai dan menyimpan dokumen pendukung serta pembuatan laporan yang menjadi lebih cepat. Penilaian dalam sistem ini menggunakan Key Performance Indikator (KPI) supaya dapat membantu pihak sekolah dalam mencapai suatu tujuan yang diinginkan dari penilaian kinerja guru. Kesimpulan dari penelitian ini adalah pembangunan dari sistem informasi penilaian kinerja guru ini dapat membantu dan memudahkan pihak sekolah dalam melakukan penilaian kinerja guru dan penyimpanan dokumen pendukung, serta sistem ini juga telah dilakukan pengujian sebelumnya dan mendapatkan nilai rata-rata yaitu 81 maka nilai ini tergolong masuk kategori “Bagus” dengan penilaian “B”.

Food packaging is the process of protecting a food product to maintain durability and quality consistency. Edible film made from porang tubers is a sustainable and innovative solution to reduce plastic waste and improve food preservation. Porang tuber (Amorphopallus muelleri blume) is a valuable plant as its high glucomannan content can be processed into porang flour. The drying process is one of the important steps in the preparation of porang tuber flour. One of the polysaccharides used in edible films is starch from glucomannan derived from Porang tubers. Glucomannan is an alternative material developed because of the high polysaccharide content in porang tubers, namely mannan, which has the ability to form a good film layer, good biocompatibility, biodegradable and has the ability to form a gel. This study was conducted with the aim to determine the effect of drying temperature on the results of edible films obtained, in terms of swelling and tensile strength values using porang tuber starch. The main stages of this research are the preparation of glycerol-plastized porang tuber flour solution and then the stage of making porang tuber flour edible film. In the manufacture of edible film, the drying process is carried out with temperature variations of 40, 50 and 600C. The highest swelling and tensile strength values were obtained in porang flour edible film at 50 0C, where the swelling and tensile strength values were 61.1% and 0.75 MPa.

Plastic waste is already polluting the environment both land and oceans, as plastic consumption continues to increase. Biodegradable plastics are an effort to reduce environmental pollution, biodegradation plastics are plastics made from natural materials usually biodegradable plastics made from natural starch. Cassava starch is the most widely used type of starch and is developed for the manufacture of biodegradable plastics, and sweet potatoes are tubers whose starch content is quite numerous even though it has not been widely developed into plastic material. This research aims to produce natural plastics that can replace conventional plastics and reduce environmental pollution due to plastic waste. The study was conducted with variations in the composition of starch mixtures (50:0 gr, 35:15 gr, 25:25 gr, 15:35 gr, 0:50 gr) and variations in drying temperatures (40°C, 50°C, 60°C).In this study carried out organoleptic test, thickness value test, water absorption value test and degradation test. The results of this study showed biodegradable plastics that have the best characteristics are in the variation of the composition of the mixture 50:0 gr at a drying temperature of 60°C, with a thickness value of 0.11 mm and a water absorption value of 36.5%, but the rate of degradation in this variation is very slow

Environmental pollution due to textile industry waste, especially synthetic dye waste, has become increasingly widespread and has become a serious concern in recent decades. Dyes such as Metanil Yellow are often found polluting waters, causing adverse impacts on ecosystems and human health due to their toxic and difficult-to-decompose nature. This study aims to identify the characteristics of hydrogels made from kepok banana peels in absorbing and degrading Metanil Yellow dye. The research methods used include organoleptic tests to determine the physical characteristics of the hydrogel, water absorption tests to measure the capacity of the hydrogel to absorb liquids, and dye degradation tests using a UV-Vis Spectrophotometer to determine the effectiveness of the hydrogel in absorbing Metanil Yellow dye. The results showed that the hydrogel had a smooth texture, had the highest water absorption capacity of 81.30% hydrogel with the addition of 0.6 grams of Sodium Tripolyphosphate, and the highest degradation of Metanil Yellow dye, which was 46.95% at a concentration of 10 ppm. %. Hydrogels made from kepok banana peels have the potential to be used as absorbers of Metanil Yellow dye.
