Abstract

Cibitung Hamlet, Ponggang Village is one of four partner villages of the Industrial Engineering Study Program of Atma Jaya University (UAJ) in community service activities. Continuing economic development for Ponggang Village, the community service team saw an opportunity in Cibitung Hamlet to plant water spinach as a selling product and increase vegetable consumption for the Ponggang Village community. To support the planting of water spinach, fertile soil, sunlight, and water are needed. Fertilization is really necessary to increase or maintain plant fertility by adding artificial or natural nutrients. The Community Service Team conducted a preliminary study on the effect of organic fertilizers, inorganic fertilizers, fertilizers from biogas dregs (bioslurry), and no fertilizers, using the soil in Cibitung Hamlet on the growth of water spinach. Based on the results of the study, fertilizers using biogas dregs provided heavy metal content values below the limit and also provided a fairly good level of water spinach growth compared to the treatment of organic fertilizers, inorganic fertilizers, and no fertilizers. The results of his study were socialised to the community of Cibitung Hamlet, Ponggang Village in the form of community service

Abstract

"Kemah Peduli Sahabat Kasih" is a care facility for individuals with mental disorders, managed by a single family. One of the primary challenges faced by the facility is the inadequate lighting for nighttime activities. In 2024, the team from the Faculty of Biosciences, Technology, and Innovation (FBTI) at Atma Jaya Catholic University of Indonesia contributed by installing two solar-powered lighting units: one along the access road to the facility and another for the front and back yard areas. However, these two lighting points were insufficient to fully support nighttime activities. Therefore, the 2025 community service program aimed to install additional lighting points at the Kemah Peduli Sahabat Kasih facility. The activity began with observations and interviews with the head and staff of the facility to assess conditions following the installation of the initial lighting units and to determine the additional lighting needs. It was found that three more lighting points were required, exceeding the initially allocated budget. As a result, a joint discussion was conducted between the Atma Jaya team, the facility head, and staff to decide that this year’s budget would be allocated to the purchase of solar-powered lamps. The community service program successfully procured three solar-powered lamps, which were tested and demonstrated satisfactory performance and illumination levels. The operational procedures and maintenance guidelines were also effectively communicated and understood by the facility’s head and staff.

Abstract

Southwest Sumba Regency is located in the province of East Nusa Tenggara, part of the Sumba Islands, which are famous for their natural beauty. This area offers a unique combination of stunning landscapes, distinctive cultural richness, and community life that still upholds local traditions. However, behind all that, there are several fundamental problems that still occur in Southwest Sumba Regency, especially stunting. Stunting is the main problem in this location. Stunting is chronic malnutrition in toddlers, which results in stunted growth in both height and weight. One of the factors causing stunting is the lack of access to clean water and proper sanitation. Clean water is very important in maintaining personal hygiene, food, and the environment so that it can prevent various diseases that can inhibit children's growth. The construction of drilled wells is one effective solution to overcome the problem of access to clean water in areas prone to stunting. With the existence of drilled wells, the community will have easier access to clean water so that it can improve the quality of life and health, especially for children. From the identified problems, the solution offered is the procurement of drilled wells with solar-powered pumps (PLTS). Thus, the problem of access to clean water and energy sources to operate the drilled well can be resolved. Then it can be developed in various locations/areas that have not received access to water. The capacity of the drilled well that has been made produces an output of 50 liters/hour. This output has been in accordance with the target of devotion.

Abstract

Perkembangan industri FnB di Indonesia terutama pada masa kini memiliki perkembangan yang sangat pesat. Badan Pusat Statistik sendiri mencatatkan pertumbuhan HOREKA (hotel, restoran dan kafe) sendiri memiliki pertumbuhan kurang lebih 12% setiap tahunnya. pelaku usaha industri FnB saat ini juga senantiasa berusaha memberikan inovasi terbaru dan pengalaman yang baik dan unik pada pelanggannya (suasana, sistem pemesanan, kualitas pelayanan, dan sejenisnya). Hal ini ditunjukkan oleh munculnya adaptasi salah satunya terhadap sistem pemesanan yang cepat saji seperti pada industri FnB kebarat-baratan. Salah satu akulturasi budaya Indonesia dengan sistem pemesanan kebarat-baratan adalah pada Restoran Nasi Uduk Hebring yang berlokasi di Kelapa Gading, Jakarta Utara. Meski memiliki fokus utama dari sistem pemesanan yang mengadaptasi kondisi cepat saji, masih ditemukan sejumlah masalah didalam sistem ini, salah satunya adalah lamanya waktu pelanggan yang harus menunggu yang secara langsung memberikan kesan buruk terhadap pelayanan restoran. Dalam penelitian ini dilakukan simulasi menggunakan software Promodel untuk mengetahui kondisi awal dari rangkaian sistem yang ada, mengidentifikasi permasalahan yang ada, dan mengeliminasi permasalahan yang ada dengan usulan yang telah disimulasikan dan bersifat valid. Penelitian dilakukan dengan pengamatan secara langsung dan mengumpulkan data dalam satuan waktu dari sejumlah kegiatan restoran. Data yang telah dikumpulkan kemudian akan diuji dan dimasukkan kedalam model yang telah dibentuk secara riil oleh peneliti melalui software Promodel. Dari 3 usulan yang diusulkan, ditetapkan kesimpulan bahwa usulan-3 yaitu penambahan kasir dan pelayan masing-masing berjumlah 1, memberikan peningkatan secara langsung dari jumlah pelanggan yang selesai dilayani pada jam sibuk restoran menjadi 47 pelanggan yang semula berjumlah 32 pelanggan (kenaikan 46,88%).

Abstract

The long patient waiting time in general outpatient services has become a major problem at Clinic XYZ, particularly during the screening stage and doctor consultations at peak hours. This condition negatively affects patient satisfaction and service effectiveness. This study aims to identify the causes of prolonged waiting times, propose alternative improvements, and evaluate the effectiveness of solutions through simulation using ProModel software. The simulation model was developed to represent real conditions and test several improvement scenarios. The results show that nearly 50% of patients’ time in the system is spent waiting. Four improvement proposals were suggested, namely adding more doctors, redistributing nurses’ tasks, increasing screening capacity, and implementing a single-queue system. The best proposal, which applies consistently to both morning and afternoon sessions, is the addition of doctors. Based on the analysis, this solution proved to be the most effective, reducing total waiting time by 39.75% in the morning scenario and 33.74% in the afternoon scenario. This recommendation provides a strategic basis for improving service efficiency and patient satisfaction at Clinic XYZ.

Abstract

White Express merupakan perusahaan franchise dari Jepang yang bergerak di bidang jasa Laundry dan Dry Clean. White Express Indonesia, didirikan dengan nama PT. Nugerah Surya Indonesia. White Express memiliki permasalahan pada lama waktu proses pencucian disertai dengan tidak pastinya kedatangan order. Penelitian ini bertujuan untuk memberikan solusi untuk perbaikan yang ada pada sistem dengan simulasi promodel. Penelitian ini hanya dilakukan pada lantai pencucian kemeja/t-shirt dan sprei/bed cover, serta tidak memperhitungkan biaya fasilitas pembersihan dan biaya operasional. Penelitian dilakukan dengan proses pengambilan data selama dua minggu untuk mengamati kondisi yang terjadi selama sistem berlangsung. Hasil dari penelitian ini didapatkann bahwa terdapat waktu menunggu yang cukup lama pada bagian pemilihan pakaian. Hal ini mengakibatkan terjadi nya adanya penumpukan yang terjadi pada lokasi pemilahan. Kesimpulan pada penelitian ini adalah kondisi awal yang terjadi pada saat pengamatan dan simulasi memiliki permasalahan yang sama yaitu adanya waktu menunggu pada proses pemilihan pakaian sehingga terjadi penumpukan pada pakaian kotor. Usulan yang diberikan pada penelitian ini berupa penambahan tenaga kerja pada bagian pemilahan pakaian, dengan usulan ini waktu menunggu pada proses pemilahan dapat berkurang sebesar 6.81 menit.
