Abstract

Indonesia's horticulture sector has undergone rapid expansion, driven by rising demand from both domestic and international markets. However, small-scale farmers continue to struggle with limited market access, price volatility, and high production costs, affecting their profitability and long-term sustainability. This study conducted a comprehensive literature review of 135 scientific articles to analyze three dominant supply chain models: direct marketing, contract farming, and cooperatives. Direct marketing allows farmers to secure higher prices by bypassing intermediaries but poses challenges in terms of operational scale, financial resources, and market access. Contract farming provides stability through guaranteed pricing, input support, and technical assistance, though profit distribution often favors contracting firms. Meanwhile, cooperatives offer better market access and collective bargaining power but require strong organizational structures to function effectively. The findings emphasize the importance of policies that support farmer education, improve market infrastructure, and encourage fair contractual agreements. Additionally, agribusiness stakeholders must invest in supply chain innovations and risk mitigation strategies to enhance efficiency and transparency. Strengthening these aspects is crucial for fostering a more resilient and sustainable horticultural sector in Indonesia

Abstract

This study explores the potential of agroecology in developing a sustainable sugar palm agroindustry in Deli Serdang Regency, North Sumatra, Indonesia. The sugar palm (Arenga pinnata) is a vital economic resource, yet its development faces limited technology, traditional management practices, and low-quality seed availability. The research aims to analyze the demographic characteristics influencing the adoption of agroecological principles among sugar palm craftsmen and assess the agroindustry's sustainability and productivity. A qualitative descriptive approach was employed, involving in-depth interviews with 100 respondents, including sugar palm farmers and craftsmen, alongside secondary data from the Central Statistics Agency. The findings reveal that most artisans are in the productive age group, with low formal education but significant practical experience. While 65% of respondents practice crop diversification, challenges remain in soil conservation and adopting environmentally friendly technologies. The study forecasts increased palm sugar production, projecting growth from 664.4 tons in 2022 to 790.8 tons by 2026, indicating potential for enhanced productivity. Integrating traditional knowledge with modern agroecological practices is essential for improving sustainability and competitiveness in the sugar palm agroindustry. Training programs that respect traditional values while promoting sustainable practices are necessary to empower artisans and enhance regional food security. This research underscores the importance of community collaboration among farmers, government, and research institutions to foster a more resilient and equitable agroecological system.

Abstract

Local rice seeds are crucial to Indonesia's food security and agricultural sustainability, especially in West Sumatra. Seed management has yet to achieve seed independence, hindering the development of breeders and seed users. Overcoming this requires collaboration between stakeholders because locals can take collective responsibility and build trust in the Government through collaborative seed governance. This study introduces the concept of assessing the level of collaboration between stakeholders to analyze the stages of cooperation currently occurring in the governance of local rice seeds in West Sumatra. This study employs a mixed-methods approach, combining quantitative and qualitative methods. The study involved interviews with experts and a literature review, identifying 14 indicators influencing collaboration in seed governance. After validation by 5 (five) Experts, 13 (thirteen) indicators were obtained for further analysis using the Fuzzy Delphi, which was applied through a questionnaire distributed to 30 (thirty) informants representing stakeholders in five Regencies/Cities selected purposively in West Sumatra Province. The results were analyzed using a Likert scale and converted to fuzzy logic. These indicators are categorized into 5 (five) characteristics of collaboration. This study found that the level of collaboration between stakeholders is at the "cooperation" stage, which shows a significant lack of effectiveness in the interaction between stakeholders. This study offers valuable insights for stakeholders to enhance the collaborative process of local rice seed management, thereby achieving food security and sustainable agriculture.

Abstract

The building sector consumes about 30% of the world's primary energy demand. Conventionally, reducing building energy consumption is done through energy saving or energy conservation activities. Nearly zero energy building (nZEB) itself can be defined as a provision that implies a value of energy consumption that is as low as possible or an energy-efficient building, then determines the energy source that is able to meet these energy needs. These strategies can generally be done with passive design, active design, and comprehensive energy management approaches [6]. This article presents an overview of the implementation of nZEB and finds out the shortcomings in terms of strategies and techniques used for different types of buildings and climates. Given the differences in climate and building characteristics, we found that each region has different challenges in applying the nZEB concept.

Abstract

The sequence of product assembly affects the efficiency and effectiveness of production because it reduces cycle time and production costs and reduces production errors. The application of artificial intelligence is growing to optimize the problem of assembly sequences of components or products, including genetic algorithms and fuzzy logic. These two models can complement each other to produce the best assembly sequence. This research consists of several stages: model formulation, model analysis, solution, and model verification and validation. A hybrid fuzzy and genetic algorithms model can optimize product assembly sequences more effectively and efficiently. Fuzzy logic can help determine the variables that must be optimized, while genetic algorithms can help find the optimal solution by combining these variables. Experiments using hybrid fuzzy logic and genetic algorithms to minimize assembly cycle time have resulted in product part assembly sequences that accommodate all geometric constraints, including assistive devices.

Abstract

Indonesia is listed as the second largest contributor to plastic waste in the world. The problem currently faced is the increasing amount of plastic waste which is one result of the business processes of companies using plastic packaging or plastic packaging manufacturers, one of the plastic packaging waste that comes from cooking oil packaging. The method to solve the problem of processing cooking oil packaging waste carried out in this study is to modify the existing system into a reverse logistics system. Currently, cooking oil companies have not implemented reverse logistics to reduce plastic packaging production. The reverse logistics system applied in this study is to modify cooking oil packages into packages that can be used repeatedly. The reverse logistics system that is applied is then modeled linerly to find out the minimal costs in implementing reverse logistics for the packaged cooking oil. Based on the development of the packaged cooking oil waste management model, it is known that the results of determining the model solution with the linear programming model are the minimal costs for reverse logistics of packaged cooking oil. The model is designed to do a sensitivity analysis by making changes to the reverse logistics cost parameters, changes in the reverse logistics cost parameters resulting in changes to the results that are directly proportional. The designed model is implemented using PT. XYZ which has a similarity with the designed system.

Abstract

This study aims to map the most potential vegetables to be developed in West Sumatra Province.The Location Quotient (LQ) method is employed to identify leading and non-leading commodities,while the Shift Share Analysis (SSA) is used to analyze structural changes and the competitivenessof the commodities. The study utilizes secondary data in the form of vegetable sub-sectorhorticultural production data by regency/city over a six-year period (2017–2022). The results showthat large chili is the leading vegetable commodity in West Sumatra, with an LQ value greater than1 across 17 regencies/cities. Conversely, garlic is categorized as a non-leading commodity, with anLQ > 1 found in only one regency. Nevertheless, garlic is identified as the most progressivecommodity based on the highest net shift value. Net growth of vegetable sub-sector commoditieswas identified in 10 out of 18 regencies/cities, with Solok Regency contributing the most. In termsof individual commodities, cabbage recorded the highest net growth, while chayote experienced thelowest. The resulting commodity mapping can serve as a basis for local government in formulatingspatial and sustainable development policies, as well as a strategic reference for businesses andinvestors in directing horticultural investments in West Sumatra.

Abstract

Koto Tangah Sub-district is a sub-district where part of its area is located on the coast, making it prone to tsunami disasters. Despite the fact that the large number of exposures in the tsunami red zone predicted to happen in this District, there are only three tsunami shelters in the red zone of Koto Tangah District. The purpose of this study was to determine the distribution of official shelters in Koto Tangah District, the distribution of planned shelters, and the coverage of shelter service areas. The research method used is a quantitative descriptive method. In this study, what is discussed is the number and location of shelters, as well as the location of the planned tsunami shelters. Also, this present study sought to finding out the coverage area that can be served by the shelter with the help of GIS applications. The results of the data analysis are as follows: (1) There are nine villages (kel.) that are in the tsunami red zone of the Koto Tangah District and are not served by official shelters, namely: Kel. Padang Sarai, Kel. Batipuh Panjang, Kel. Lubuk Buaya, Kel. Pasia Nan Tigo, Kel. Batang Kabung Ganting, Kel. Koto Pulai, Kel. Koto Panjang Ikua Koto, Ex. Dadok Stumping Black, and parts of Ex. Parupuk Tabing. (2) The analyzed planned shelters and horizontal points examined that all of the Koto Tangah red zone areas can be served by shelters, and the planned shelters can be reached in the span of 34.5 minutes with a distance of 1554.57 m, meaning that people who are in the tsunami red zone can evacuate safely before the tsunami hits the city. (3) local government needs to add another 6 planned shelters in Kel. Padang Sarai, Kel. Lubuk Buaya, Kel. Pasie Nan Tigo, Kel. Batang Kabung Ganting, and Kel. Parupuk Tabing, with each shelter's planned height of 8.5 meters.

Abstract

Disasters may make people having to evacuate. When evacuating, evacuee may bring items required in evacuation place. The items must be ready previously in a bag, called a disaster preparedness bag. In case a disaster occurs, evacuee just grabs it and go for evacuation. Many bags used are not dedicated for disaster situation. Many types of items stored together and mixed causing of difficulty in retrieval. In addition, use of inappropriate bag will interfere with evacuee movement and slow down the evacuee while the evacuation time is too short. This research aims to design ergonomics disaster preparedness bag that can accommodate needs for 3x24 hours. Design process was started with planning phase to find out disaster preparedness bag development opportunity. The second phase is concept development. People who have evacuation experience are asked report their complaints regarding the bag used during previous evacuation and their needs for a disaster preparedness bag. Based on the needs, target specification is determined then concept alternatives are generated and selected. Then, main parts of the bag are identified. Continued with detailed design process, the dimensions of the proposed bag are determined using anthropometric data and dimension of required item in the first 72 hours of evacuation time. The design of proposed bag is such a backpack with multi compartments adjusted to item stored. The shoulder straps are designed like a vest then the load is not focused only on the shoulder but distributed to other part of body such as abdominal and chest muscle.
