Saat proses penggilingan padi, kulit padi akan terkupas dan terpisah dari beras, sehingga sekam padi ini menjadi limbah dari proses penggilingan padi yang selanjutnya disebut sekam padi. Di desa ini, saat masa panen, banyak limbah sekam padi yang menumpuk dan umumnya kurang dimanfaatkan. Sampai saat ini, limbah sekam padi hanya ditumpuk atau dijadikan bahan untuk abu gosok. Adanya potensi limbah sekam di desa dapat dimanfaatkan menjadi bioadsorben dan menjadi peluang masyarakat desa dalam meningkatkan pendapatan ekonomi. Program ini bertujuan untuk memberikan sosialisasi dan pembekalan materi kepada masyarakat agar dapat mengolah limbah sekam padi menjadi bioadsorben. Produk bioadsorben ini sangat bermanfaat bagi kehidupan, diantaranya dapat berfungsi sebagai bioadsorben penyerap limbah logam berat juga dapat dijual kepada pabrik/industri yang membutuhkan bioadsorben untuk menangani limbah usahanya. Dengan telah terlaksananya program Pemberdayaan kemitraan masyarakat ini, masyarakat Desa Cot Puklat sudah memiliki pengetahuan dalam pemanfaatan limbah sekam padi menjadi bioadsorben.","PeriodicalId":17758,"journal":{"name":"Jurnal Serambi Engineering","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139320792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Delays in the delivery of electrical goods from suppliers, specifically PT. X, PT. Y, and PT. Z, impedes the operational workflows of the company. The study employed the Analytic Hierarchy Process (AHP) methodology to conduct the research. This involved constructing a hierarchical or network structure of the problem and conducting a pairwise comparison stage afterward. The findings reveal the key factors that significantly impact the supplier selection process for electrical items at PT.

The intersection of Damang Batu Road - Pilau Road is located in the urban area of Palangka Raya. This intersection is a very important traffic meeting point as it must facilitate rapid movement throughout the area. Analyzing the performance of the intersection is an important factor in identifying the most effective strategies to improve its efficiency. This study was conducted with the aim of analysing the intersection performance and obtaining alternatives to optimise the intersection performance. This research uses observational methodology, where data collection is carried out in a field situation. After all the data both primary and secondary are collected, the data will be analysed using the MKJI 1997. According to the results, under current conditions it has shown good results. The capacity value is 2434 smp/hour. And the degree of saturation is 0.51. Meanwhile, the intersection delay is 10.779 sec/smp.

The purpose of this research is to determine the best conditions for the synthesis of cellulose acetate from bagasse and test how cellulose acetate can be used to make biodegradable foam. This study used phosphoric acid as a solvent and glacial acetic acid as an acetylating agent to make cellulose acetate through the acetylation process. The variations in acetylation time in this study were 15, 30, and 45 minutes and the volume of glacial acetic acid as acetylating agent was 20, 40, 60, 80, and 100 ml. The results of this study indicated that the optimum conditions for the synthesis of cellulose acetate are 15 minutes of acetylation with a volume of 100 ml of glacial acetic acid, with a yield of 79.31% cellulose acetate, 36.19% acetyl content and a degree of substitution of 2.11. The test for the application of cellulose acetate to make biodegradable foam obtained a water absorption of 18.81%, the biodegradation test obtained was 24.53% in 14 days. In the biodegradable foam leak test for 10 minutes, no leakage occurred.

Demikian juga halnya dengan volume bioetanol yang dihasilkan setelah pemurnian, dimana volume bioetanol dari limbah kulit nenas lebih banyak diperoleh yaitu sebesar 3,5 mL dibandingkan dengan bioetanol dari limbah kulit jeruk jeruk yaitu hanya sebesar 3,3 mL. Hal ini disebabkan oleh kadar gula yang terkandung didalam kulit nenas lebih tinggi dibandingkan yang terkandung dalam kulit jeruk.
