Abstract

Indonesia has abundant biodiversity, yet its utilization is still limited to traditional consumption and has not been widely developed into economically valuable products. The leaves of galingale (Cassia alata) contain flavonoids, alkaloids, and tannins that are beneficial as antibacterials and antifungals, while the moringa leaves (Moringa oleifera) are rich in antioxidants, vitamins, and minerals beneficial for skin health. One local wisdom of the Kalimantan community is the pupur babigi, a traditional powder made from natural ingredients, which is now being abandoned due to the influx of modern cosmetic products. This community service activity aims to: (1) increase public knowledge about the contents and benefits of galingale and moringa leaves, (2) train the community in making pupur babigi, and (3) encourage the creation of micro-enterprises based on herbal products. The methods include preparation, socialization, practical training, mentoring, and evaluation, involving 25 participants (housewives and youth from the community). The results show an increase in participants' understanding from 20% (pre-training) to 85% (post-training). All participants were able to produce pupur babigi of good quality, and 80% expressed interest in developing the product as a business. In addition to skills transfer, this activity also raised collective awareness about the importance of utilizing local natural resources for economic empowerment.

Abstract

Effective maintenance is an essential factor in ensuring the reliability and availability of equipment, especially for heavy equipment that operates intensively. This study aims to optimize the maintenance interval of excavator units by considering the value of reliability against time, to obtain a balance between reducing the risk of failure and maximizing operational availability. Historical data of time between failures (TBF) and time to repair (TTR) were collected from a PC 200 excavator unit operating in a coal mine in South Kalimantan from January 2024 to June 2025. Initial analysis was carried out using a Pareto diagram to identify critical systems, followed by failure mode and effect analysis (FMEA) to determine repair priorities. TBF and TTR modeling were tested with four probability distributions (Normal, Lognormal, Weibull, and Exponential) using the Anderson–Darling goodness-of-fit test, with the result that both data follow a Lognormal distribution. Distribution parameters were used to calculate mean time between failures (MTBF), mean time to repair (MTTR), the reliability function R(t), and availability. The results show an increase in availability from 96.15% to 96.59% after implementing the selected distribution, as well as a decrease in MTTR from 11.21 hours to 9.92 hours. Analysis of the relationship between reliability and availability resulted in an optimal maintenance interval in the range of 230–245 hours, when reliability remains above 90% and availability is around 96%.
