The snake fruit processing company UD Salacca faces several challenges in its snake fruit processing activities, including people, machines, methods and the environment. The aim of this research is to identify the challenges faced by UD Salacca in snake fruit production. The risk management method used in this research follows the ISO 31000:2008 guidelines using the House of Risk (HOR) Model, which includes steps for risk identification, risk analysis, risk evaluation, and risk management. 22 risk events (risk factors) have been identified from 9 process activities and 17 risk agents (risk causing factors), of which there are 5 high priority risk causes. The causes of this risk include the mixing process taking less than three hours, weather and pest factors, not being careful when loading, and not being careful in the sorting process using traditional grinding equipment. From the research results, 18 proposed mitigation strategies were found from 9 process activities. Some of the strategies proposed include the use of machines in the ripening process, the use of tools to peel snake fruit, the use of personal protective equipment when working, supervision and implementation of work operational standards during harvest, and the use of assessment checklists when sorting snake fruit. Early handling strategies are needed by salacca businesses to anticipate major risks. These results can be used to increase the company's effectiveness in handling risk management

As business competition intensifies, an organization needs to streamline operations and improve plant performance, focusing on minimizing waste. At Company XYZ, inefficient processes have led to persistent waste in crude palm oil (CPO) production, particularly in the forms of motion, waiting, and transportation. The objective of this study is to identify waste in the CPO production, analyze its root causes, and propose actionable improvements. A lean manufacturing approach was employed using Value Stream Mapping (VSM), Waste Assessment Model (WAM), Waste Assessment Questionnaire (WAQ), Value Stream Mapping Tools (VALSAT), and Cause-and-Effect Diagram methodologies. The VSM analysis revealed motion, waiting, and transportation as the primary waste categories. Waste identification using WAM ranked motion as the most significant waste (19.39%), followed by waiting (14.91%), transportation (14.57%), overproduction (14.23%), defects (14.21%), inventory (14.17%), and overprocessing (8.52%). Process Activity Mapping (PAM) identified 34 activities, with 50% being value-added, 9% non-value-added, and 41% necessary but non-value-added. This research improves operational performance and productivity in CPO production using lean tools. These interventions are expected to reduce waste and enhance operational performance significantly.

Lean systems and ergonomics are two organizational approaches that were initially practiced independently. Over time, however, it has become evident that while lean methodology emphasizes efficiency and waste reduction, it often overlooks the human factor, which can compromise worker health and safety. On the other hand, applying ergonomics without incorporating lean principles may lead to inefficiencies and increased costs. This trade-off has sparked growing interest in integrating ergonomic considerations into lean practices within manufacturing. Despite this interest, comprehensive studies on lean ergonomics remain scarce. This research aims to explore the development of lean ergonomics implementation over the past five years. Using a Systematic Literature Review (SLR) methodology, the study analyzed articles from two Scopus-indexed databases, identifying 196 articles containing the keywords Lean, Ergonomics, and Manufacturing Industries. Following the PRISMA framework and applying inclusion criteria, only 18 papers were found to thoroughly address the integrated implementation of lean ergonomics in manufacturing industries. The majority of these studies originated from Portugal (33.33%) and India (16.67%). Case studies emerged as the dominant research methodology (55.56%), leading to the development of lean ergonomic tools such as Ergo-VSM, ErgoSMED, and WIDEA. Other methodologies included literature reviews (22.22%), qualitative research (16.67%), and grounded theory (5.56%). The findings suggest that implementing lean ergonomics has positive impacts, including reduced setup times, decreased ergonomic risks, and improved workplace conditions. While ergonomic interventions may involve additional costs, these are viewed as long-term investments. In conclusion, the existing literature indicates that the implementation of lean ergonomics is still limited and lacks comprehensiveness. Future research could focus on practical applications in industry and evaluate their effectiveness to strike a balance between operational efficiency and worker well-being.

A farmer group is a social forum, as a place for a group of people to work together to achieve a common goal. Farmer groups cannot be separated from social dynamics issues because every member of the farmer group has different characteristics. However, members of groups do not understand the dynamic group, so the farmer groups that have been formed are very vulnerable to disbanding or being inactive. The purpose of this socialization activity is to provide knowledge to the farmers of the Villa Saiyo Timbalun Livestock Group about group dynamics as an effort to help create an active, solid, and sustainable group and be able to develop a business so that it can increase group income for the welfare of the group. The implementation of the activity is carried out by the extension method, namely providing socialization of strengthening livestock groups about group dynamics to the target audience. The target of the implementation of the socialization of livestock groups strengthening to the community is a group of farmers in the city of Padang, namely the Villa Saiyo Timbalun livestock group in Bungus Teluk Kabung District. The Andalas University degree carried out on the livestock group of Villa Saiyo Timbalun, Bungus Timur Village, Bungus Teluk Kabung District was carried out well and smoothly. Farmers are enthusiastic about the implementation of this socialization of livestock group strengthening, which can be seen from the presence of both group members and breeders who are around the location of the livestock group strengthening socialization. the results of the socialization activity for strengthening livestock groups through counseling on the topic of group dynamics created an agreement between group members to return to active group business together. In addition, this activity provides additional knowledge for members to maintain the sustainability of the group, and make the group active again, and it is hoped that the group can run and develop group business so that group welfare can be achieved. The discussions also provided solutions that made the group return to running a business together. It can be concluded that the socialization activity for strengthening the livestock group was carried out well so that the objectives of the activity were achieved.

West Sumatra, one of the provinces in Indonesia, is renowned for its rich cultural heritage and beautiful natural landscapes. Additionally, its agricultural sector significantly contributes to the region's Gross Regional Domestic Product (GRDP), including in Solok Selatan Regency, which boasts the Seribu Rumah Gadang area as its tourism icon. Solok Selatan Regency is also home to Lake Bontak, the only lake in the region, located within the conservation area of Kerinci Seblat National Park (TNKS), one of the gateways for climbing Mount Kerinci. The Independent Conservation Group (KKM) Bangun Rejo has been managing agro-ecotourism by establishing a Tourism Awareness Group (Pokdarwis) and farmer groups. These groups engage in integrated farming, agriculture, and livestock businesses with nature tourism at Lake Bontak. The empowerment of these community groups aims to develop sustainable agro-ecotourism in Solok Selatan Regency. One method used is Focus Group Discussions (FGD) to identify the potential for agro-ecotourism development at Lake Bontak. The outcomes of these activities include the agro-edutourism development concept, the creation of social media accounts for promotion, and the cleaning and installation of tracking paths and tourist activity guides in the Lake Bontak area. Additionally, there is an emphasis on educating the community about conducting tourism activities that prioritize biodiversity conservation within the conservation area to support ongoing environmental knowledge around Lake Bontak. It is hoped that this area will attract both local and international tourists, particularly students and researchers interested in exploring the flora and fauna potential through the agro-edutourism concept.

The definition and function of inventory management reveal the importance of modern industry in formulating policies that regulate the supply of raw materials, semi-finished products, and finished products. Unfortunately, most companies fail to consider the characteristics of their raw materials when determining inventory strategies. Raw materials that are perishable are those that consider their service life and storage time. Inventory management plays a crucial role in supply chain management, especially for perishable raw materials, such as food products. PT X, a food business in Padang, experienced difficulty in meeting the demand for rendang products due to a lack of raw materials. Therefore, this study aims to develop an inventory management model that takes into account the perishable raw materials' expiration time. The model development consists of three stages: model development design, inventory model formulation, and model testing. The proposed model resulted in a storage time interval of five days and an optimal order quantity of 34 kg of meat with a safety stock of 14 kg. Implementing this model led to lower total inventory costs for PT X than the actual conditions of the company. The total inventory cost obtained using this model is Rp279,797,822. This study emphasizes the importance of considering the characteristics of raw materials in determining inventory strategies to optimize inventory management effectively and efficiently. The study's findings can serve as a reference for other food businesses encountering similar inventory management challenges in the perishable food industry.

This research aims to evaluate the egg-laying chicken feeder that was designed at egg-laying chicken farm small and medium enterprise (SME). The main reason of this tool design was due to the worker’s complain of feeling pain during the feeding process. Evaluation was performed based on Nordic Body Map questionnaire result, physiological workload, and NIOSH lifting equation calculation. The observed work ranged from the feed filling in the basket until all feeds were distributed. The results showed that the %CVL was in the range of 18%-30% and the energy consumption of workers was in the range of 1.24-3.00 Kcal/minute. Thus, physiologically, the work activities carried out by the feed workers were categorized as very light workload. Meanwhile, evaluation using Lifting Index (LI) methods in the process of feeding showed the LI value ranged from 0.9-1, therefore this activity is safe to perform manually. Based on the prototype evaluation on the feeding aid, the process of feeding activities was more effective 1.5 times faster than the old tools. In addition, with the use of this new tool, the feeding process was easier to adjust the dose each time.

The geographical condition of Sungai Pisang Village located on the coastal fringe and not too far from the famous island tourism which potential in West Sumatera becomes an opportunity for the people of Sungai Pisang, especially the fishermen to increase their standard of living. But in reality, the outsiders in the Bungus area are more likely to take advantage of the opportunity because of their location close to the city center. The tourists can only be seen from afar by biduk fishermen of Sungai Pisang. Most tourists prefer to use Tour and Travel services from Bungus area. Biduk fishermen are only bringing few tourists to the island tour even though the price offered is much cheaper. Based on preliminary study, there are problems such as the lack of knowledge of the fisherman on the effective product marketing strategy. So far, there are no marketing tools to promote the transportation services of biduk fisherman to the island tourism in the Sungai Pisang broadly. Therefore, it is necessary to design a marketing information system for island tourism biduk. The marketing information system is a mobile web-based designed using PHP programming language and supported by the MySQL database. The information marketing system is expected to increase the number of tourists who use the island tourism biduk as an effort to increase the sustainable fishermen's economy.The geographical condition of Sungai Pisang Village located on the coastal fringe and not too far from the famous island tourism which potential in West Sumatera becomes an opportunity for the people of Sungai Pisang, especially the fishermen to increase their standard of living.

Construction project implementation process is often found inefficiency and problems at every stage of the construction process. Inefficiencies are caused because construction projects have high levels of fragmentation. The high level of fragmentation cannot be separated from the complexity and many work items on construction projects. To reduce the problem of inefficiencies in the implementation of construction projects required good supply chain management or better known as supply chain management (SCM) on construction projects. Therefore it is necessary to study the management of SCM in the construction project to reduce the inefficiency that occurred. SCM management of construction projects is done by designing SCM performance measurement systems in construction projects. This performance measurement system produces indicators that are combined with the Supply Chain Operation Reference (SCOR) method. So it helps in performing SCM performance measurement on construction projects. From the design results, obtained 14 SCM performance indicators on construction projects. The performance indicators are then used to perform SCM performance measurement of cement plant construction projects. From the measurement results obtained SCM performance value of 41 from a scale of 100. This shows the performance of SCM on construction projects for the construction of the cement plant is at a marginal level.
