Abstract

A battery is a device that can store electrical energy. Batteries are currently widely used for humanneeds such as batteries in clocks, remotes and children's toys. The batteries currently used by humans are disposable batteries, so over time they can cause environmental pollution because batteries are made from chemicals [1]. This research aims to reduce battery waste by using Ambon banana peels as a substitute for battery chemical content. The battery will be made from pure Ambon banana peel which contains potassium and chloride [2]. Chloride is a strong electrolyte that can conduct electric current and to get more electric current, Ambon banana peel is mixed with sea water. This research compares the length of use between batteries that use a seawater mixture and those that do not use a seawater mixture that will be installed on a wall clock. Batteries that use sea water have a battery life of 9 hours with a ratio of more sea water, the same amount, and more banana peels. The voltage produced by more sea water is 1.53 V with a current of 0.00069 and a power of 0.0010557 W. The voltage produced by the same ratio of sea water and banana peel is 1.65 V with a current of 0.00059 A and power 0.0009735 W. The voltage produced by comparing banana peels is more than sea water at 1.43 V with a current of 0.00064 A and a power of 0.0009152 W, while the battery that is not mixed with sea water only lasts 4 hours with the resulting voltage of 1.44 V with acurrent of 0.00082 and a power of 0.001180 W. So it can be concluded that research using an equal ratio of sea water and banana peel is the most optimalcomparison in this research because it has the highest stress level.Chemicals; Ambon Banana Peel, Sea water, Electrolyte, Bio Battery.

Abstract

Micro Hydro Power Plant is a small scale power plant that uses hydropower as its energy source. The power to drive the PLTMH turbine is in the form of water flow originating from irrigation canals and rivers. The undershot turbine is a type of water turbine that utilizes river flow or irrigation channels as the driving force for the undershot turbine. In this research, based on the problems used in undershot turbines in order to get maximum results, the researcher designed a PLTMH prototype by analyzing the effect of the number of blades and the turbine blade model on the power produced by the generator in the undershot turbine of a micro hydro power plant so that it would be known that the number of blades was 12 , 14, 18 and the triangular blade model which obtains better PLTMH output. In this study, the number of blades was 14 which was the best with a resulting voltage of 9.4 volts, a current of 0.96 amperes and a power of 9.02 watts.

Abstract

Limited equipment and limited skills are hindering the promotion of the Kesuma Bangsa Herbal Garden Agrotourism. Lack of knowledge of modern production techniques and efficient practices leads to low capacity. Furthermore, inconsistent quality is a challenge due to inefficient introduction and marketing. The lack of a clear and measurable business plan, particularly in terms of manual financial record-keeping, poses a risk of errors in cash management, which ultimately negatively impacts business sustainability. Limited knowledge of marketing and promotion, limited access to markets and distribution networks, and less than optimal use of digital marketing methods. Consequently, the Kesuma Bangsa Herbal Garden Agrotourism market access is limited. Through this community service, the Kesuma Bangsa Herbal Garden Agrotourism market will be expanded not only locally but also nationally. The Kesuma Bangsa Herbal Garden Agrotourism still faces limitations in digital marketing, particularly in understanding information technology that can be used to improve its business. This limitation impacts partners' lack of digital marketing skills. The Kesuma Bangsa Herbal Garden Agrotourism product lacks a clear branding strategy to differentiate its products in the market. This makes it difficult for the business to grow and compete, especially with other MSMEs that already have their own unique offerings. The problem formulation must be stated concretely and clearly in the introduction. Explain the objectives to be achieved through the community service activities with measurable and realistic targets. Also outline the expected benefits of the community service activities for both the target audience and the development of knowledge.

Abstract

Low-voltage cable insulation degradation poses a significant risk to the reliability and safety of power distribution systems, particularly under combined thermal and environmental stress conditions. This study investigates the dominant degradation mechanisms affecting low-voltage cable insulation in distribution networks, using field measurements at the PR009 transformer substation as a representative case. The analysis focuses on the interaction between thermal overloading, electrical stress, moisture ingress, and environmental contamination, and their cumulative impact on insulation performance. A quantitative experimental field approach was employed, integrating insulation resistance testing, dielectric loss (tan δ) analysis, partial discharge evaluation, and theoretical modeling of electrical and thermal behavior. The results indicate that excessive current loading and phase imbalance lead to elevated conductor temperatures, intensifying thermal stress and accelerating insulation aging. Intrinsic electrical breakdown, streamer-induced partial discharge activity, dielectric losses, and limited heat dissipation were identified as primary contributors to degradation. Environmental factors, particularly high humidity and acidic soil conditions, were found to further exacerbate chemical and mechanical deterioration of polymeric insulation materials. The findings highlight the effectiveness of condition-based diagnostic techniques for early detection of insulation deterioration and support the implementation of predictive maintenance strategies. This study provides practical insights for utilities and asset managers to enhance service reliability, reduce unplanned outages, and optimize the lifecycle management of low-voltage distribution cables under realistic operating and environmental conditions.
