Abstract

Konsep mengenai Sustainable Supply Chain Management (SSCM) menarik perhatian akademisi dan praktisi dengan konsep triple bottom line (ekonomi, sosial, lingkungan). Dalam menjalankan manajemen rantai pasok, melalui kinerja ekonomis mempertimbangkan faktor lingkungan dan sosial. Usaha mengurangi dampak buruk bagi kehidupan social dan lingkungan adalah hal yang dipertimbangkan dalam SSCM dengan menerapkan konsep tersebut ke dalam seluruh jaringan rantai pasok. Penerapan SSCM menjadi sangat rumit karena mempertimbangkan banyak hal, penelitian yang berkembang berkisar pada manajemen operasional. Sedangkan diskusi dari sisi konsumen tidak banyak dibahas. Penelitian ini bertujuan untuk mengetahui topik bahasan yang didiskusikan oleh publik terkait SSCM. Dengan metode Natural Language Processing (NLP), diskusi publik pada platform Twitter disarikan untuk mendapatkan daftar topik. Hasil dari ekstraksi topik diskusi pada platform twitter ini menunjukkan bahwa pembahasan mengenai ekonomi dan lingkungan lebih banyak didiskusikan daripada faktor sosial. Hal ini dapat terjadi karena adanya kemungkinan konsep mengenai Green SCM sudah lebih dahulu dikenal. Konsep ini membahas mengenai faktor lingkungan yang perlu dipertimbangkan dalam SCM

Abstract

Organic waste management is an important issue in addressing environmental problems. One potential solution is bioconversion technology using Black Soldier Fly (BSF) maggots that can break down organic waste and produce larvae with economic value as animal feed. To increase the selling value and extend the shelf life, BSF larvae need to be dried using tools such as rotary dryers. This study aims to design and analyse the strength of a rotary dryer machine frame for maggot drying with a Finite Element Analysis (FEA) approach based on SolidWorks software. Simulations were carried out on several materials: ASTM A36, AISI 1020 Steel, and AISI 1045 Steel. The analysis results show that all materials are within safe limits based on Von Mises stress, deformation, and safety factor. AISI 1045 steel material gives the best performance with Von Mises stress of 14.238 MPa, deformation of 0.59 mm, and safety factor of 7.2. These results show that AISI 1045 steel is the most recommended material for the rotary dryer frame.

Abstract

One method of drying Black Soldier Fly (BSF) larvae that can be applied is drying using a continuous microwave oven. This tool utilizes microwaves emitted to evaporate water. In addition, the use of a conveyor that runs on a microwave oven as a medium or place to place BSF larvae is expected to simplify the production process. This study was conducted to determine the design and strength analysis of the thermal structure of a continuous microwave oven-type BSF larva dryer using Solidworks software. The specifications of the continuous microwave oven-type BSF larva dryer have a capacity of 15 kg, a heating input power of 8 KW and a temperature of 100℃. With variations in heating time of 20, 30, and 40 minutes. The results of the thermal structure analysis of the BSF larva dryer type continuous microwave oven based on the simulation obtained stress with the highest value of and the lowest value of . The results of the displacement simulation with the highest value of and the lowest value of . The Safety factor simulation result is 3.2. So from the simulation results it can be said that it is safe to continue to the manufacturing process.
