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

Students often experience difficulty translating graphic representations into symbolic mathematical forms, indicating the need for learning resources that connect abstract concepts with meaningful contexts. This study aimed to develop an e-module based on Realistic Mathematics Education (RME) integrated with the ethnomathematics of rumah betang to improve students’ ability to transform graphic representations into symbolic representations. This research employed a development design using the ADDIE model, comprising analysis, design, development, implementation, and evaluation. The feasibility of the e-module was evaluated by material and media experts. Its practicality was examined through a small-group trial, while its effectiveness was tested in a large-group implementation using pretest and posttest scores. Expert validation indicated that the e-module was categorized as “very feasible” in terms of material and media quality. The small-group trial showed that the e-module was “practical” for use in mathematics learning. In the large-group trial, students’ average score increased from 63.92 on the pretest to 84.72 on the posttest. The N-gain score was 0.59, indicating a medium improvement, with an effectiveness percentage of 58.81%, categorized as moderate. The findings suggest that the RME-based e-module integrated with rumah betang ethnomathematics is feasible, practical, and moderately effective in supporting students’ representation ability. The e-module can be used by teachers as an innovative culturally contextualized learning medium and by students for independent or collaborative learning. Further studies may examine its effects on other mathematical abilities, such as critical thinking and problem solving.

Abstract

This research identifies various types of insect vectors that are capable of spreading disease-causing viruses in sugarcane plants in Indonesia and explores methods of controlling them. The main vector insects are from the order Hemiptera, which have piercing and sucking type mouthparts. These insects play an important role in the spread of viruses such as sugarcane mosaic virus (SCMV), sugarcane streak mosaic virus (SCSMV), and sugarcane yellow leaf virus (SCYLV), which can cause significant deterrence in national sugarcane productivity. This research uses a qualitative modeling approach by reviewing the literature to collect data regarding methods of controlling virus vector insects. The research results show that insect vector control must be carried out in an integrated manner, prioritizing technical and biological control methods as well as routine monitoring. The use of insecticides is recommended only if the insect population increases significantly. These results provide practical guidance for reducing the negative impact of insect vectors on sugarcane productivity in Indonesia.

Abstract

Each community has unique needs that must be met, including clothing, food and shelter. Among these three basic needs, the need for food has the highest urgency and must be met with an adequate nutritional composition to support optimal health. This research aims to increase individual knowledge and skills, especially in semi-finished food production, in order to encourage the development of entrepreneurial individuals who can apply the entrepreneurial mindset and skills they have learned during higher education and then share these abilities with the wider community. This research uses problem solving strategies to examine the process of establishing a business, especially in the food industry. The research method involves data collection techniques such as in-depth interviews and periodic monitoring. Data analysis was carried out using the SWOT analysis method. The research results showed a significant increase in participants' knowledge and motivation regarding new business founding strategies. Additionally, they gain an in-depth understanding of effective food processing techniques for long-term storage while maintaining nutritional quality. Furthermore, the community demonstrated the ability to store and process food in accordance with quality standards set by the governmen.

Abstract

Coffee farming is a major source of livelihood for rural communities, but its sustainability is threatened by weak managerial capacity, low technology adoption, and landslide risks. This community service activity aims to strengthen the economic independence of the “Bangun Semi” Coffee Farmer Group in Donorejo Village, Purworejo. The program was implemented using a Participatory Action Research (PAR) approach through the stages of socialization, training, technology application, mentoring, and evaluation. Interventions included digital bookkeeping training, strengthening the branding and digital marketing of Kopi Semi, installing a solar-powered coffee roasting machine, utilizing coffee husk waste into fermented animal feed, and implementing a Landslide Early Warning System (LEWS). The results showed an increase in business capacity and partner resilience. The selling price of coffee increased by more than 120%, roasting productivity rose from 2 kg/day to 12 kg/day, and energy costs decreased by up to 88%. In addition, the utilization of coffee husk waste reduced feed costs by up to 20%, while LEWS strengthened early warning and community preparedness. This integrated model is effective in strengthening a resilient local economic independence and has the potential to be replicated in other disaster-prone areas.

Abstract

This study aims to explain the relationship between viral marketing and destination image variables on the intention to visit the city of Semarang. The sample in this study was 100 respondents. In comparison, the implementation of sampling in this study uses an accidental sampling technique, namely the technique of taking samples by chance from the respondents. The data analysis technique used multiple regression. The results of statistical tests concluded that (1) there is a positive and significant relationship between viral marketing and the intention to visit, which means that the higher the viral marketing in a city, the higher the intention to visit, and the second result (2) there is a correlation which is positive and significant between destination image and intention to visit, meaning that the better the destination image, the higher the intention to visit made by consumers to visit the city of Semarang. Conversely, the worse the viral marketing and destination image of consumers, the lower the intention to visit made by consumers. Findings : This research proves that with viral content and a good image of a tourist destination, it can make tourists interested in visiting the city of Semarang.
