Abstract

Raw material inventory is an important factor that influences company profits. CV. XYZ is a company engaged in the production of precast concrete. This company has not implemented special methods in planning and scheduling production. So far, companies have only relied on predictions of consumer needs without proper analysis, so they often experience excesses or shortages of raw materials. This research aims to determine the optimal amount of raw material inventory using the Material Requirement Planning (MRP) method. Data collection techniques include interviews, literature study, observations and observations. Calculations are carried out using the lot sizing method to determine the quantity and frequency of orders as well as total inventory costs. The analysis results show that the MRP method using the Periodic Order Quantity (POQ) technique produces lower total costs compared to Economic Order Quantity (EOQ). By applying the MRP method with the POQ technique, companies can optimize raw material inventory and minimize total inventory costs.

Abstract

Serious challenges in the agro-industry—such as operational inefficiencies, process bottlenecks, and suboptimal post-harvest facility layouts—directly reduce productivity, product quality, and profitability. While numerous studies have examined agricultural process improvements, a significant empirical gap exists between 2022 and 2026 regarding the comprehensive integration of industrial techniques—particularly Lean Manufacturing, Six Sigma, and Discrete-Event Simulation (DES)—in the context of sustainable food systems. This study aims to identify post-harvest operational problem patterns and the most effective optimization approaches through a PRISMA-based Systematic Literature Review (SLR) and a cross-case study synthesis. Secondary data were collected from publications in Scopus, Web of Science, and Google Scholar from 2022–2026, with analysis including waste mapping, bottleneck evaluation, layout analysis, and process simulation. The SLR results (n=38 articles) indicate that key post-harvest bottlenecks include excessive cycle times, process queues, overhandling, non-linear layouts, and low digital integration. Case studies show that the combination of Lean–Six Sigma–DES can reduce lead time by 15–45%, reduce waste by 20–60%, increase OEE (Overall Equipment Effectiveness) by up to 18%, and increase profitability by 12–30%. This research confirms the significant contribution of industrial engineering in realizing a sustainable agricultural system, increasing supply chain efficiency, and optimizing the added value of the agro-industry, becoming a reference for MSMEs, farmers, and policymakers

Abstract

PT. XYZ merupakan pabrik pengolahan air minum dalam kemasan yang beroperasi di bawah naungan Danone Indonesia. Ketepatan waktu pengiriman produk menjadi salah satu faktor penting dalam menjaga kepuasan pelanggan. Penelitian ini bertujuan untuk menganalisis penyebab keterlambatan pengiriman produk ke distributor menggunakan metode Failure Mode and Effect Analysis (FMEA). Metode FMEA digunakan untuk mengidentifikasi potensi kegagalan serta menentukan prioritas risiko berdasarkan nilai Risk Priority Number (RPN) yang diperoleh dari parameter Severity, Occurrence, dan Detection. Hasil penelitian menunjukkan bahwa pada bulan Desember 2024, keterlambatan pengiriman paling sering disebabkan oleh kekosongan botol atau jumlah botol yang tidak sesuai permintaan, yaitu sebanyak 229 pengiriman atau 85% dari total keterlambatan. Namun, hasil analisis FMEA menunjukkan bahwa faktor gangguan kesehatan sopir memiliki nilai RPN tertinggi sebesar 448 atau 64% dari total nilai RPN. Hal ini mengindikasikan bahwa meskipun frekuensi kejadian kesehatan sopir relatif rendah, tingkat keparahan dampak dan kesulitan deteksi yang tinggi menjadikan faktor tersebut sebagai prioritas utama perbaikan.

Abstract

Purpose: This study aims to explain the process of transformative Islamic education in community-based plastic waste management through a combination of pyrolysis technology and biomass in Manikrejo Village, Pasuruan Regency, and to analyze its impact on changing paradigms, community independence, and the creation of circular economic value.Design/methodology/approach: This research employs a qualitative case study approach with data collection through participant observation, in-depth interviews with 35 informants consisting of religious leaders, village officials, waste management group administrators, training participants, and sub-district government representatives, as well as documentation during the community service program from June to December 2025. Data analysis uses an interactive model and triangulation to ensure validity.Findings: The results reveal three main stages in transformative Islamic education through this program. First, internalization of Islamic values such as cleanliness, moral responsibility, and mutual cooperation becomes the motivational foundation driving community participation, with religious figures acting as catalysts for behavioral change. Second, the implementation of learning-by-doing methods with tiered mentorship successfully transforms residents from passive recipients into competent technology operators, with 90% of participants able to operate pyrolysis reactors independently. Third, a fundamental paradigm shift occurs where plastic waste is no longer viewed as an "environmental burden" but as a "potential raw material" with economic and functional value. The program produces measurable impacts: every 5 kg of plastic waste is converted into 3.5 liters of pyrolysis oil and 1 kg of biochar, creating environmental, economic, and social benefits simultaneously.Research limitations/implications: This study is limited to one village context in Pasuruan Regency, East Java. However, it provides valuable insights for the development of transformative Islamic education models in non-formal and community-based settings, and offers an alternative approach for Islamic educational institutions facing the challenge of integrating spiritual values with appropriate technology and environmental sustainability.Originality/value: This research contributes to the literature on transformative Islamic education by documenting a proven community-based educational approach that integrates spiritual values, local wisdom, and circular economy principles. The learning-by-doing method combined with tiered mentorship represents a modern adaptation of the sanad system in Islamic scholarly tradition, offering a replicable framework for similar programs in other rural contexts in Indonesia and other developing countries.

Abstract

Sampah plastik menjadi permasalahan lingkungan mendesak di Indonesia, di mana 4,9 juta ton dari total 7,8 juta ton sampah plastik per tahun tidak terkelola dengan baik (World Bank, 2021). Di Desa Ngadimulyo, Kecamatan Sukorejo, Kabupaten Pasuruan, kondisi ini diperparah oleh rendahnya kesadaran masyarakat, terbukti hanya 100 dari 600 KK yang aktif dalam sistem pengelolaan sampah desa. Kegiatan pengabdian kepada masyarakat (PKM) ini dilaksanakan untuk membangun sistem pengelolaan sampah plastik berbasis ekonomi sirkular sekaligus mengubah pola pikir masyarakat secara mendasar melalui pendekatan Teori U (Presencing Theory). Metode pelaksanaan mengintegrasikan lima fase Teori U – co-initiating, co-sensing, presencing, co-creating, dan co-evolving, dengan pelatihan teknologi tepat guna, lokakarya reflektif, dan pendampingan berbasis komunitas. Hasil kegiatan menunjukkan tiga inovasi produk bernilai ekonomi: (1) ecobrick dari sampah plastik non-organik, (2) kompos dari limbah dapur rumah tangga, dan (3) bata ekologis dari abu sisa pembakaran sampah. Terbentuknya unit Bank Sampah Plastik Desa membuktikan terjadinya transformasi pola pikir masyarakat dari paradigma linier "gunakan-buang" menuju kesadaran sirkular yang menempatkan sampah sebagai sumber daya ekonomi. Program ini berkontribusi terhadap pencapaian SDGs 11 dan 12 tentang komunitas berkelanjutan serta pola konsumsi dan produksi yang bertanggung jawab.

Abstract

Effective machine maintenance is key to ensuring productivity and operational efficiency in the industrial sector, where although preventive maintenance has become the standard, technological developments are now introducing more advanced predictive maintenance strategies, but a comprehensive comparison of the effectiveness of these two approaches in improving machine performance is still limited. This study aims to conduct a systematic review and meta-analysis of the efficacy of preventive and predictive maintenance methods, especially in the manufacturing industry, through a literature search in Scopus, Web of Science, and IEEE Xplore databases with related keywords, where empirical studies comparing both methods and their impacts on machine performance, including availability, reliability, and maintenance costs, are included. Meta-analysis was used to measure the difference in effectiveness between the methods, with study quality assessed using the AMSTAR checklist. The results showed that of the 25 studies that met the inclusion criteria, predictive maintenance was shown to be more effective in improving availability than preventive maintenance (effect size = 0.75, 95% CI: 0.60-0.90, p < 0.01), where factors such as cost, technology level, and machine type influenced the selection of the optimal maintenance method. This systematic review indicates that predictive maintenance is more effective in improving machine performance than preventive methods. However, the choice of the optimal method must be tailored to the specific industry context, and these findings are essential for decision-making in industrial maintenance management.
