Abstract

This study investigates the risk levels and potential for work accidents in manufacturing processes involving heavy equipment like lathes, which often lead to accidents due to non-compliance with safety regulations. Employing job safety analysis (JSA), the research aims to minimize accidents by assessing risk levels and proposing comprehensive Personal Protective Equipment (PPE) usage for workers. Results reveal that the welding process's failure mode severity is rated at 2, while lathe-related accidents, particularly exposure to debris, have the highest occurrence and effect analysis at 6. Limited PPE availability contributes to a low failure mode detection and effect analysis score of 7. This study underscores the critical need for implementing stringent safety measures to mitigate workplace accidents in manufacturing settings. Highlights : Comprehensive assessment: Utilizing job safety analysis (JSA), the study provides a detailed evaluation of potential work accidents in manufacturing processes, focusing on heavy equipment usage. Risk mitigation: The research emphasizes the importance of implementing stringent safety measures, including the complete utilization of Personal Protective Equipment (PPE), to minimize the occurrence of workplace accidents. Importance of compliance: Non-compliance with safety regulations, particularly regarding the use of PPE and adherence to K3 regulations, significantly increases the risk of work accidents, leading to disruptions in production processes. Keywords: Workplace Safety, Manufacturing, Job Safety Analysis, Personal Protective Equipment, Risk Assessment

Abstract

This study was aimed to depict the characteristics of women's vulnerability, as well as to study and analyze their efforts to reduce the disaster risk of Merapi eruption. This research is a survey research using descriptive quantitative method. The results showed that women were vulnerable in terms of their financial security, particularly due to their lack of bank saving, protection in the place of business, land, and residence. Their social vulnerability was shown by how most of the women and elderly people in the households of the area under study required protection when disaster occurred. The vulnerability in organizations was due to the lack of organizations to care for the women.

Abstract

Composites with natural fiber reinforcement have special characteristics that imitation fibers do not have. Sansevieria fiber as one of the producers of good quality natural fiber, as research has been done, has good potential to be developed. This study discusses the manufacture and characteristics of plant fiber composites (sensevieria) with a polyester matrix using the hand lay up method. This composite uses a volume fraction of 30% with woven fiber treatment and NaOH immersion as much as 0%, 4%, 7%, 10%, 13%, and 15% for 4 hours at room temperature. In this research, it is aimed to determine the mechanical properties of this composite by performing a tensile test, with the standard ASTM D638 – 03. namely: the highest tensile strength was found in the 10% NaOH immersion variable with a volume fraction of 30% matrix, amounting to 12.855 N/mm2. So that the best strain value is 0.105 in the specimen with 15% NaOH immersion and the highest elastic modulus value is found in the fiber with 4% immersion, which is 201.5 N/mm2

Abstract

Jenang Al Husna memiliki 12 karyawan, beroperasi dari pukul 08.00 sampai 16.00 menggunakan sistem borongan. Memiliki kapasitas produksi 300 Kg perhari, gabungan dari beras ketan, santan, dan gula aren. Proses pembuatan jenang, bahan direbus bersamaan dan diaduk selama 4 jam sampai mengental, jenang yang sudah matang, didinginkan selama 24 jam, selanjutnya dilakukan pemotongan dan pengemasan. Permasalahan mitra dalam produksi adalah, 1) Pemotongan jenang dilakukan secara manual sehingga membutuhkan waktu yang cukup lama dan tidak akurat dalam ukuran tiap potong jenang, 2) Kapasitas produksi tidak memenuhi permintaan pasar, 3) Tidak memiliki standard operating procedure. Solusi yang diberikan kepada mitra pada PKM ini adalah 1) Membuat mesin pemotong jenang untuk meningkatkan efektifitas dan efisiensi produksi, 2) Membuat kemasan produk untuk meningkatkan nilai barang. 3) Membuat Standard Operational Procedure melalui Forum Group Discussion. Luaran dari PKM ini adalah kapasitas produksi meningkat sebesar 65%, kualitas produk lebih baik dan peningkatan pengelolaan manajemen operasional.
