Abstract

Labour serves as a critical resource that has a significant impact on a company's operations and financial results, particularly in the oil and gas sector, which contributes to national economic development. This research focuses on evaluating the impact of workforce size on the financial performance of PT Migas using regression and correlation analysis techniques. The study uses financial ratios such as return on assets (ROA), return on equity (ROE), earnings before interest, tax, depreciation and amortisation (EBITDA) and operating costs as data variables. The results show a weak inverse relationship between the number of employees and ROA, with a correlation coefficient of -0.526, indicating a negative association. Similarly, the correlation between the number of employees and ROE is calculated at -0.332, while the correlations with operating expenses and EBITDA are -0.991 and -0.848 respectively, all indicating a negative trend. Over the three-year analysis period, the results show that the size of the workforce does not have a significant impact on financial performance. This highlights the potential influence of other factors on firm performance and the need for management to implement more efficient workforce strategies. This study aims to provide valuable quantitative insights for management in formulating labour-related policies to support the company's future financial growth.

Abstract

Background: In the animal feed manufacturing industry, machine reliability is essential for uninterrupted operations. Specific Background: PT XYZ, a poultry feed producer, experiences production inefficiencies due to frequent Hammer Mill failures. Knowledge Gap: Despite the critical role of machine reliability, limited studies address risk prioritization and mitigation strategies using integrative methods in this context. Aim: This study aims to identify and mitigate the dominant risk factors contributing to Hammer Mill failures through a structured risk management approach. Results: Using the House of Risk (HOR) Phase 1, five major risk agents were identified based on their Aggregate Risk Potential (ARP): lack of routine maintenance (ARP 1496), overused components (ARP 1080), foreign particle contamination (ARP 861), voltage fluctuations (ARP 510), and machine overload (ARP 432). Root Cause Analysis (RCA) traced the origin of these risks, and HOR Phase 2 prioritized mitigation actions using the Effectiveness to Difficulty Ratio (ETD). Novelty: The study integrates HOR and RCA to offer a quantitative and root-focused risk management framework. Implications: The proposed preventive maintenance scheduling system, identified as the most effective mitigation strategy, provides a replicable model for reducing downtime and enhancing production efficiency in industrial settings. Highlights: Identifies key risk factors causing machine failure. Combines HOR and RCA for effective mitigation. Proposes a preventive maintenance system to reduce downtime.

Abstract

Masih banyak penggunaan pengawet berbahan kimia yang berbahaya bagi kesehatan di Indonesia, sehingga penting untuk mencari alternatif lain dengan memanfaatkan bahan-bahan alami sebagai pengawet tradisional. Kelurahan Kejawan Putih Tambak Kota Surabaya memiliki potensi besar dalam pengembangan ide inovatif berupa pengawetan alami dengan memanfaatkan daun mangrove (Rhizophora sp). Dalam kegiatan ini penulis melalui beberapa tahap. Pertama, penulis mengumpulkan referensi untuk mengetahui inovasi apa yang dapat dilakukan di wilayah RT 05. Kedua, penulis melakukan survei ke lokasi tumbuhnya mangrove dan mengumpulkan daun mangrove yang akan digunakan menjadi pengawet ikan. Ketiga, penulis menetapkan sasaran peserta yang merupakan ibu rumah tangga. Keempat, penulis melakukan sosialisasi inovasi di gazebo RT 05 RW 02 Kejawan Putih Tambak. Pada tahap terakhir, dilakukan praktik pembuatan pengawet dari daun mangrove. Peserta sangat interaktif, ditandakan dengan banyaknya pertanyaan yang diajukan selama kegiatan berlangsung. Dilihat dari antusias peserta sosialisasi, penulis rasa pengembangan pengawet alami yang aman, efektif, dan ramah lingkungan mendapat respon positif dari masyarakat sekitar karena banyak yang menyatakan keinginan untuk mengembangkan inovasi ini sebagai usaha bersama masyarakat. Sehingga tujuan untuk mengurangi penggunaan bahan pengawet kimia sintetis yang berpotensi merusak lingkungan dan kesehatan sedikit banyak dapat tercapai dengan keberlanjutan inovasi yang dijalankan oleh masyarakat.
