Abstract

Banten 1 Suralaya Power Plant is a Coal-Fired Steam Power Plant. The issue at hand is the high downtime of the coal pulverizer system, which experienced 195 failures across the seven coal pulverizer systems in 2023, resulting in a total downtime of 1,020.3 hours. This research focuses on Coal Pulverizer System C, which had the highest downtime, averaging 274 hours in 2023. The aim is to identify the factors causing the failures and to propose a maintenance scheduling plan. This research employs the Reliability Centered Maintenance method, which is a logical engineering process to determine maintenance tasks that will ensure a reliability system design under specific operating conditions in a particular operational environment using a downtime analysis approach. The proposed maintenance scheduling is based on the calculations of Mean Time Between Failure and Mean Time To Repair. Based on the downtime analysis, it is known that the performance of the Coal Pulverizer C system is still optimal with an average availability of 94%. A failure mode of the Coal Feeder component was identified with an RPN of 320 as the dominant cause of the damage. Additionally, from the Function Block Diagram and Logic Tree Analysis, 2 failure modes were found in category B (Outage Problem) and 5 failure modes in category C. (Economic Problem). With the Reliability Centered Maintenance method based on the calculations of Mean Time Between Failure and Mean Time To Repair, a maintenance schedule is proposed for the components of the Coal Pulverizer System C, namely: Pulverizer Body every 115 days, Pulverizer Motor every 76 days, Lube Oil System every 15 days, Coal Feeder every 25 days, Coal Feeder Motor every 57 days, Control Instrument & Indicator System for Pulverizer every 32 days, and Control Instrument & Indicator for Coal Feeder every 46 days.

Abstract

A common problem often faced by companie is the instability if the supply of raw materials needed by the company. Likewise, the Nadin’s Onion Chips Business has not implemented a stable raw materials inventory control system. The aim of this research is to control raw material inventory to determine the optimal inventory cost value. The methods used are Economic order Interval (EOI) and Lagrange Multplier. Based on the results, the cost of supplies for tapioca flour was IDR 429.204, wheat flour IDR 429.204, eggs IDR 151.514, garlic IDR 151.578, shallots IDR 172.706, celery IDR 107.301, vegetable oil IDR 239.918 , salt amounting to Rp. 177.822 and flavorings amounting to IDR. 176.394. Meanwhile, using the Lagrange Multiplier method produces inventory costs for tapioca flour of IDR 435.081, wheat flour of IDR 454.352, eggs of IDR 193.917, garlic of IDR 156.468, shallots of IDR 183.314, celery of IDR 113.702, oil vegetables amounting to IDR 243.355, salt amounting to IDR 183.053 and flavorings amounting to IDR 179.815. From the calculation results it can be concluded that the EOI method is more optimal than the Lagrange Multiplier method because EOI has minimum inventory costs.

Abstract

Pengoptimalan daya pikir anak tentunya juga didukung oleh asupan gizi yang diserap oleh tubuh dan otak anak. Anak dengan gizi yang baik dan seimbang tentunya mengalami tumbuh kembang yang baik pula, namun kenyataannya banyak para orang tua yang kurang memperhatikan dikarenakan kurangnya pengetahuan mengenai gizi seimbang. Kebanyakan orang tua hanya memperhatikan anak mau makan tanpa memahami apakah asupan gizi sudah terpenuhi dengan baik atau belum dalam makanan tersebut. Maka dari itu perlu dilakukan edukasi tentang gizi seimbang pada anak usia dini di masyarakat, khususnya di Kelurahan Nyapah yang menjadi salah satu mitra pengabdian kepada masyarakat. Sasarannya adalah para orang tua di kelurahan Nyapah agar memiliki pemahaman dan pengetahuan yang baik mengenai gizi seimbang untuk anak usia dini. Kegiatan ini dilakukan selama 3 hari dan diikuti 25 orang tua yang memiliki anak-anak usia dini. Peserta sangat antusias dan bersemangat menerima materi yang diberikan dan melakukan diskusi interaktif. Hasil pre test dan post test menunjukkan bahwa ada peningkatan rata-rata pengetahuan orang tua dari 63,45 menjadi 75,13 setelah mengikuti edukasi gizi seimbang ini. Secara keseluruhan kegiatan pengabdian kepada masyarakat ini dapat dikatakan berhasil. Para orang tua mulai menyadari pentingnya gizi seimbang untuk tumbuh kembang anak. Kata Kunci: Anak Usia Dini, Gizi, Kesehatan, Pengetahuan Orang Tua.

Abstract

Problem-solving ability has been recognized as a key competency in 21st-century learning, particularly in statistics education, where students are required to analyze data and interpret results accurately. Integrating digital tools such as R software is considered essential for supporting these competencies, as they enable students to explore data, perform computations, and visualize outputs effectively. This study aimed to examine the effectiveness of the Think-Pair-Share model assisted by R software (TPS-R) in improving students' problem-solving abilities in statistics courses. A quantitative approach using a quasi-experimental design was employed, involving two groups: an experimental class applying TPS-R and a control class applying the Think-Pair-Share model without R software (TPS-WR). The results showed a significant difference in problem-solving abilities between the two groups, with the TPS-R class demonstrating higher performance (Mann-Whitney U = 215.0, Z=−2.428, p = 0.017). These findings indicate that integrating TPS with R software serves as an effective instructional strategy in statistics courses, provided that instructors manage class time efficiently and guide students' learning processes appropriately.

Abstract

The high prevalance of underutilized vacant land in Pontang District constitutes an urgent issue. Vacant land can become a practical entry point for community-based greening when it is managed through collective action rather than left as an unused open space. This article describes the seedling planting movement carried out by Community Service Program team of Group 32, Universitas Bina Bangsa, at the Pontang District field, Serang Regency, Banten. The activity involved community service team, the Pontang village head, neighborhood units RT 01 to RT 12, RW 02, Bhabinkamtibmas, Pontang Police Sector, Karang Taruna, and surrounding residents. A descriptive qualitative approach was applied using participatory observation, field documentation, and a review of recent literature on vacant-land greening, urban green infrastructure, ecosystem services, and community stewardship. The results show that the program functioned as an initial transformation of open vacant land into a planted space while also creating direct collaboration among village institutions, security actors, youth organizations, community service team, and residents. The environmental contribution identified in this article is still an early-stage potential because temperature, air quality, soil quality, and seedling survival were not measured quantitatively. Therefore, the main implication is the need to continue post-planting maintenance, periodic monitoring, and clearer responsibility sharing so that the planted seedlings can develop into durable green infrastructure rather than remain a one-time ceremonial activity.

Abstract

This community service activity was conducted to develop processed payus fish products through the innovation of bontot (fish bone) into a dry snack called Boring (Dried Bontot) in Pontang Village. This development was motivated by the potential of local food ingredients that have not been optimally utilized to produce products with higher economic value. Payus fish bontot, previously known as a local processed food, was developed through a diversification process to provide a more practical presentation and meet consumer needs. The activity implemented a participatory approach, involving the community in several stages: product identification, information dissemination on food diversification, processing bontot into dry products, packaging, and introducing marketing strategies. The results of the activity indicate that the development of Boring can be an alternative to expand the use of payus fish-based products. The resulting product is dry and more practical for consumption and packaging. Furthermore, the activity provided additional knowledge to the community about the importance of innovation, packaging, and product identity in increasing the attractiveness of a local product. With this development, Boring has the potential to be developed into a superior product based on the local potential of Pontang Village. Sustainable development through product quality enhancements, flavor variations, packaging design, branding, and digital marketing is expected to increase sales value while supporting the growth of local MSMEs.

Abstract

Human reliability is one of the factors that influences the quality of painting results. This activity has the potential for human error, which can lead to product defects, reduced quality, and increased operational costs. This study aims to determine the HEP in the painting process and to propose improvement recommendations to enhance the effectiveness of the painting process. One of the methods used to assess human reliability in this study is the HEART. Data were collected through observations, interviews, documentation, FGD, and questionnaires administered to thirty workers involved in the painting process. The analysis was conducted by calculating the Human Error Probability (HEP) and human reliability values, which were then classified into low, moderate, high, or very high categories. The results showed that the highest Human Error Probability (HEP) value was 0.265, found in the subtasks of mixing thinner and paint as well as spraying the mixed paint, with a reliability value of 73.4% (categorized as high reliability, below 80%). Recommended improvements include routine maintenance of spray gun equipment, technical training for operators, ensuring adequate rest time, and enhancing worker discipline toward Standard Operating Procedures (SOP).

Abstract

Banten Sukses Mandiri is a manufacturing company engaged in the production of light steel, using coils as its primary raw material. Demand for channel steel has led to an imbalance in raw material inventory. To address this issue, raw material (coil) requirements were planned using the Material Requirements Planning (MRP) method to identify the most efficient lot sizing technique. The analysis included the Moving Average (MA) and Exponential Smoothing (ES) forecasting techniques, as well as the Material Requirements Planning (MRP) method, with a comparison of lot sizing techniques: Fixed Order Quantity (FOQ), Economic Order Quantity (EOQ), and Period Order Quantity (POQ). The results of the study indicate that the Moving Average forecasting method (N=6) is the best approach, with a MAPE accuracy value of 0.48%. Based on MRP calculations, the total net requirement for coil raw materials was determined to be 309,151 kg. The results indicate that the Period Order Quantity (POQ) technique is the most efficient, as it yields the lowest total inventory cost of Rp. 5,002,406,962 with an ordering frequency of 5 times.
