Abstract

The church is a place of worship for Christians. Its presence is expected to provide both physical and spiritual tranquility. To achieve this, church facilities must strive to offer comfort to their users, such as the congregation's prayer benches. However, some of these prayer benches fail to provide sufficient comfort because, historically, church bench designs are relics from the past, dating back to when the church was first established, and did not take comfort into account during their design. This is also the case at the Catholic Church of St. John the Evangelist in Kudus, where the congregation's prayer benches are still the original design from when the church was founded. As a result, there have been several complaints about the discomfort from users. The method used in this study employs an ergonomic approach to redesign the congregation's prayer benches at the Catholic Church of St. John the Evangelist in Kudus. Anthropometric data used to design the prayer benches were gathered from Javanese and Chinese ethnic groups, both male and female. The results of the study yielded a design for the prayer benches at the Catholic Church of St. John the Evangelist in Kudus, with the following dimensions: prayer bench length = 334.96 cm; bench width = 43.80 cm; bench height = 39.2 cm; shoulder rest height = 47.53 cm; and prayer handrest height = 60.17 cm. Another outcome of this study is the implication for the church congregation, which is an increased perception of comfort in the design of the prayer benches through the ergonomic approach.

Abstract

XYZ is an electronics company that requires an efficient and timely production process to meet market demand. One way to increase production efficiency is to improve the production line. Currently the company is faced with production problems, namely the existence of unbalanced work groups which have a balance loss value of up to 61%. Therefore, this study tries to solve these problems using the RPW method. The RPW (Ranked Positional Weight) method is a track balancing method by establishing a work station based on the weight of each operation. Where the highest weight becomes the first order in the formation of work stations. From the results of calculations using the RPW, the number of work activity groupings is less, namely as many as 10 work stations. The work station generated using the RPW method has a track efficiency level of 96% with a balance delay value of 4%. This means that the grouping of proposed work activities has a more efficient trajectory balance than the previous grouping of work activities..

Abstract

This paper tries to model agile supply chain management performance indicators in the palm oil industry. The interpretative Structural Modeling (ISM) method is used to find the relationship between these indicators. The ISM stages begin with identifying indicators, compiling contextual relationships, compiling reachability matrices, compiling level partitions, compiling digraphs, and compiling ISM models. Then MICMAC analysis is used to group each of these indicators into four categories based on their driving power and dependence power. In this study, 16 hands of agile supply chain management in the palm oil industry were obtained, of which the four-level ISM model could be constructed. Two indicators are at level 4, six hands are at level 3, three indicators are at level 2, and five indicators are at level 1. Meanwhile, through MICMAC analysis, five indicators are found in the independent indicators category, six hands are in the linkage indicator category, four indicators are included in the dependent indicator category, and one indicator is in the autonomous indicator category. This research can be used by managers in the palm oil industry who want to increase agility in their supply chain. In general, indicators at level 4 can affect indicators at level 3, and so on. So that management can start fixing the indicators at level 4 first. In addition, indicators that have a driving power value in MICMAC analysis can be prioritized to improve their performance.

Abstract

Kudus Regency has shown significant progress in education, as reflected in its highest Human Development Index (HDI) achievement among the former Pati Residency region. Amid increasing competition among schools, particularly private vocational high schools (SMK), SMK Kristen Nusantara Kudus has experienced a decline in student enrollment due to suboptimal promotional strategies. This challenge demands a digital-based promotional approach, including the use of social media and segmented marketing strategies tailored to target audiences. Therefore, a community service program was initiated in the form of training on school marketing strategies to enhance the school's competitiveness and attractiveness during the student admission period (PPDB). The goal of this community service activity is to provide training and assistance to the school management in designing and implementing effective, digital-based school marketing strategies, aimed at improving visibility, attractiveness, and the number of new student enrollments. The method used in this program involved several stages: socialization, training, implementation, mentoring, and sustainability. The program was attended by all teachers and staff of the school. The community service activities at SMK Kristen Nusantara Kudus have successfully improved the understanding and skills of teachers and staff in planning and executing effective school marketing strategies for PPDB. The outcomes include a better understanding of digital-based marketing strategies, and improved school visibility and public image through social media content. This activity showed positive impacts, such as increased digital interaction and a 30% increase in enrollment from the previous academic year.

Abstract

Water hyacinth is an aquatic plant that is often considered a weed because of its rapid growth and can disturb aquatic ecosystems. However, water hyacinth has great potential as an alternative livestock feed, especially for poultry, because of nutritional content such as protein, fiber, and carotenoids which are quite high. This article discusses the innovation of utilizing water hyacinth in Kirig Village as poultry livestock feed through a fermentation process that increases the nutritional value and digestibility of the feed. The fermentation method using microorganisms and natural materials such as molasses aims to improve feed quality and accelerate the growth of poultry livestock. This program not only helps overcome the problem of water hyacinth as a weed, but also supports food security and the sustainability of livestock businesses in the village. The results of the training and socialization show the enthusiasm of the community in adopting this innovation as a practical and economical solution in poultry livestock cultivation at the local level.

Abstract

Distribusi merupakan elemen penting dalam rantai pasok yang secara langsung memengaruhi efisiensi biaya operasional, ketepatan waktu pengiriman, serta kepuasan pelanggan. PT XYZ mengalami kendala dalam sistem distribusinya karena penentuan rute masih dilakukan secara manual berdasarkan intuisi dispatcher, tanpa mempertimbangkan faktor jarak tempuh, kapasitas kendaraan, maupun efisiensi biaya. Hal ini berdampak pada tingginya total jarak distribusi, ketidakseimbangan beban kerja pengemudi, serta meningkatnya biaya operasional. Penelitian ini bertujuan untuk mengoptimalkan rute distribusi dengan mengusulkan pendekatan hybrid yang menggabungkan algoritma Clarke and Wright Saving Heuristic dan algoritma Evolutionary dengan bantuan Excel Solver. Algoritma Clarke and Wright digunakan untuk membentuk rute distribusi berdasarkan nilai penghematan terbesar dengan tetap memperhatikan kapasitas kendaraan, sementara algoritma Evolutionary diterapkan untuk mengoptimalkan urutan kunjungan pelanggan pada setiap rute agar total jarak tempuh dapat diminimalkan. Pendekatan yang digunakan dalam penelitian ini adalah metode kuantitatif, dengan pengumpulan data melalui observasi, wawancara, dan studi pustaka. Hasil penelitian menunjukkan bahwa metode yang diusulkan mampu menghasilkan enam rute distribusi dengan total jarak tempuh sebesar 516,7 km, lebih rendah dibandingkan rute awal sebesar 1.122 km, sehingga terjadi penghematan jarak sebesar 53,9%. Selain itu, biaya distribusi juga menurun dari Rp1.054.167 menjadi Rp344.122 per hari atau berkurang sebesar 67,36%. Pengurangan jumlah rute dari sembilan menjadi enam juga menunjukkan peningkatan pemanfaatan armada, dengan potensi penggunaan tiga kendaraan untuk keperluan lain. Temuan ini menunjukkan bahwa pendekatan hybrid yang diterapkan efektif dalam meningkatkan efisiensi distribusi serta memberikan manfaat praktis bagi perusahaan dalam pengambilan keputusan operasional terkait optimasi rute distribusi.
