Abstract

The sustainable patchouli cultivation development program aims to promote community-driven agricultural practices through academic support from higher education institutions. Implemented in Teuladan Village, Aceh Besar Regency, the program utilizes the Triple Helix collaboration model, engaging academia, the community, and industry to ensure long-term sustainability. By employing a participatory approach, the initiative provides mentoring activities, including training on cultivation techniques, land management, and market dynamics for patchouli oil. Prospective farmers are selected through the CFCL (Candidate Farmers and Candidate Locations) questionnaire, which evaluates readiness based on skills, institutional organization, availability of extension workers, use of fuel for oil distillation, and commitment levels. The program aims to enhance farmers' knowledge and skills in producing high-quality patchouli, with a focus on Aceh Besar and extending across the Aceh region. By fostering sustainable agricultural practices and improving production quality, the initiative seeks to elevate community welfare and support the economic resilience of rural areas.

Abstract

Language barriers remain a critical challenge for Indonesian students pursuing higher education abroad, potentially hindering their academic success. This study aims to analyze the effect of language skills on academic performance using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with multigroup analysis. Data were collected through an online survey from 100 Indonesian STEM students studying in Asia and Europe, selected using probability sampling. The analysis confirmed a significant positive effect of language skills on academic performance (path coefficient = 0.464; p < 0.001). However, multigroup analysis showed no significant moderating effect of instruction language, study destination, or learning system (p > 0.05 for all groups). These findings highlight that language skills consistently influence academic outcomes across different contexts. The study provides empirical evidence to support the development of targeted language support programs and inclusive academic strategies for Indonesian students abroad.

Abstract

This study aims to analyze the implementation of reverse logistics in handling ceramic tableware products at PT. Lucky Indah Keramik, from end users back to the company. This activity provides benefits such as waste reduction, product cycle optimization, resource utilization, and improved customer satisfaction. The research method uses a descriptive approach, analyzing five dimensions: What, How, Who, Where, and Why and Why Not to evaluate the company's reverse logistics practices. The results indicate that PT. Lucky Indah Keramik has established clear return procedures, covering inspection flow, reverse logistics design, stakeholders, locations, motivations, obstacles, and corrective actions. The company also strives to optimize reverse logistics through reuse, repair, remanufacturing, and recycling to create an efficient and eco-friendly industry. Unusable ceramic waste is repurposed as aggregate material or handicrafts, minimizing environmental impact. The study concludes that PT. Lucky Indah Keramik's reverse logistics system operates systematically, supporting operational efficiency and environmental sustainability.

Abstract

PT XYZ is a company engaged in the processing of palm oil into Crude Palm Oil (CPO) and Palm Kernel Oil (PKO), operating in Berau, East Kalimantan. During the production process, there are efficiency-related issues. Therefore, this study aims to improve the efficiency of palm oil production by identifying value streams and waste using the Waste Assessment Model (WAM). The goal is to determine the most dominant waste type during CPO production and analyze the production process in detail using Value Stream Mapping (VSM). The VSM results reveal six workstations with a total of 15 operators, a lead time of 314 minutes, and value-added time of 174 minutes, resulting in a Process Cycle Efficiency (PCE) of 55,41% by applying the WAM method, waiting time emerges as the most dominant waste, accounting for 23,43%. Factors contributing to this waste include operator skill gaps, communication issues, and unexpected absences. Based on Process Activity Mapping (PAM), operational activities constitute the largest percentage (61,60%), with a value-added activity rate of 73.42%. Proposed improvements involve eliminating non-value-added activities, reducing the total lead time to 237 minutes, and increasing the PCE to 73.41%. These enhancements include implementing the 5S concept to minimize waste and enhance efficiency.
