Abstract

Based on the problem formulation in this research, the goal that can be formulated in this research is to be able to distribute products using optimal distribution routes and minimize transportation costs at PT. Unilever Indonesia Makassar Depot. This research uses the Nearest Neighbor method approach to determine the shortest route so that the distribution path can be done optimally. Optimal means the amount of goods sent, delivery time, and the distance required is right, in this case there are many routes. Based on calculations carried out in completing the CVRP using the Nearest Neighbor method, the total distance traveled was 1,940.2 km. Meanwhile, the company's current total mileage is 2,348 km. This shows that the Nearest Neighbor method is effective in determining the distribution route for Sariwangi Tea at PT. Unilever Indonesia Makassar Depot.  This research focuses on the distribution of goods from the company's depot (warehouse) to its customers. Delivery of goods involves services provided by the company within a predetermined time period to a number of customers using certain vehicles where the depot location can be at one or more locations. The results of this research provide input for future deliveries. It is hoped that companies can use new distribution routes using the Nearest Neighbor method, so that delivery costs can be controlled by using shorter or closest delivery routes and the costs are optimal. PT Unilever Indonesia is a subsidiary of Unilever which was founded in 1933. Having produced many well-known products, PT Unilever Indonesia is one of the large companies that contributes to meeting various community needs. As a company operating in the distribution sector, determining delivery routes is very important to consider time efficiency and minimize transportation costs.

Abstract

Appropriate Technology (AT) is widely applied in the agricultural sector to improve post-harvest productivity, including the use of corn shellers. However, many existing corn shellers have not fully considered usability and ergonomic aspects, which may lead to inefficiency, errors, and increased cognitive and physical workload for users. This study aims to evaluate the usability of a corn sheller and identify physiological parameters that indicate usability levels. An experimental method was employed involving two groups of participants, namely novice users and experienced users. Usability evaluation was conducted using the System Usability Scale (SUS), user performance indicators (task completion rate, task completion time, and error rate), and physiological measurements in the form of body temperature changes before and after task execution. The results showed that experienced users achieved a higher average SUS score (88.50, excellent usability) compared to novice users (58.50, marginal usability). Experienced users completed tasks faster, achieved a 100% task completion rate, and made fewer errors. Novice users required longer completion times, showed higher error rates, and experienced greater increases in body temperature. The findings indicate that usability is strongly influenced by user experience and cognitive factors. Body temperature changes can be used as an objective physiological indicator of usability and workload. Improvements in system learnability and user guidance are recommended to enhance usability for novice users.

Abstract

The disconnection in the transmission of maritime knowledge to partners in Southern Thailand poses a serious challenge to the preservation of cultural identity. The activity partner, Madrasah Tahfidz Al-Qur’an Addalawiyah in Pattani, faces obstacles in contextualizing its revelation based curriculum with modern technological advancements. This community service program aims to bridge this gap through an ethno techno religious approach. The implementation employs the Participatory Action Learning (PAL) method, which integrates the philosophy of Phinisi shipbuilding, Critical Path Method (CPM) project management, and the interpretation of Kauniyah verses. Therefore, a structured process of introducing Bugis-Makassar culture through sharing sessions using storytelling and discussion methods is necessary. The results of the activity indicate that: (1) internalizing the values of Siri’ na Pacce in ship construction can awaken students’ collective memory of their ancestral heritage; (2) the application of the PERT/CPM method in shipbuilding simulations provides a concrete understanding of time management aligned with Q.S. Al-‘Asr; and (3) the emergence of a new paradigm in which shipbuilding technology is understood as a tangible manifestation of the teachings of the Qur’an. This program recommends an integrative education model that positions local wisdom as the entry point for science learning in faith-based educational institutions

Abstract

Kegiatan Pengabdian Kepada Masyarakat bertujuan memberikan literasi atau kampanye terkait kewirausahaan halalfood dengan metode ceramah dan diskusi yang diberikan kepada para santri dan pengurus pondok pesantren yangberada dalam lingkungan Yayasan Pondok Pesantren Hizul Wathan dengan instrumen pengukuran menggunakanpre-test dan post test yang berupa kuesioner. Pengabdian masyarakat ini dilaksanakan dengan jumlah partisipansebanyak 23 orang. Sebelum diberikan pemahaman atau literasi mengenai kewirausahaan halal food, kewirausahaanhalal food pada kegiatan ini dikur dengan menggunakan empat aspek variabel yakni kesadaran halal, penyembelihanhalal, serifikat halal dan kewirausahaan halal, hasil pre-test menunjukkan bahwa nilai terendah untuk aspeksertifikat halal adalah 51 dengan nilai tertinggi sebesar 94 dengan rata-rata niai keseluruhan sebesar 64, kemudianhasil pre-test menunjukkan bahwa nilai terendah untuk aspek penyembelihan halal adalah sebesar 54 dengan nilaitertinggi sebesar 88 dengan rata-rata nilai keseluruhan sebesar 73, kemudian hasil pre-test menunjukkan bahwa nilaiterendah untuk aspek kesadaran halal adalah sebesar 60 dengan nilai tertinggi sebesar 87 dengan rata-rata nilaikeseluruhan sebesar 72, kemudian hasil pre-test menunjukkan bahwa nilai terendah untuk aspek kewirausahaanhalal adalah sebesar 54 dengan nilai tertinggi sebesar 88 dengan rata-rata nilai keseluruhan sebesar 67. Setelahdilakukan penyuluhan dengan metode ceramah dan diskusi, hasil post test menunjukkan nilai rata-rata untukkeseluruhan aspek secara berurutan yakni 97, 96, 95 dan 95. Berdasarkan hasil tersebut dapat ditarik kesimpulanbahwa terjadi kenaikan signifikan (setelah diadakannya pengabidan masyarakat) terhadap pengetahuan masyarakattentang kewirausahaan halal food.

Abstract

The use of information systems requires special management and management, so this system is commonly referred to as a management information system. In it there are various activities ranging from system planning, maintenance, to measuring performance. In running a library information system, software and hardware are needed as well as humans as operators. The above components must be activities that are interconnected so that the library can run smoothly. To determine whether the components of the information system are running well, it requires an evaluation process.The purpose of this study is to measure the level of satisfaction of system users and to determine the strengths and weaknesses of the system in the use of library information systems. The method used is the analytical method PIECES Framework, which consists of several points of analysis, namely: Performance, Information and Data, Economics, Control and Security, Efficiency, and Service. Where each analysis point is a reference for evaluation and analysis of information systems.The results of this study are web applications that are able to analyze the level of user satisfaction with the library information system using the PIECES Framework analysis method and equipped with a satisfaction level reporting chart of the system measured in the 2018 period
