Abstract

Ground Enhancement Material (GEM) plays a crucial role in lightning protection systems by effectively channeling lightning voltage into the ground. Given Indonesia's reliance on imports, it is essential to explore domestic alternatives for GEM production. This study assesses the feasibility of establishing a local GEM production startup in Tasikmalaya, West Java, based on technological and financial aspects. The analysis assumes a production capacity of 300 kg per day, an interest rate of 10%, and an economic life of 10 years. The technical aspect includes considerations such as business location, raw materials, and process/equipment technology. The financial aspect employs the Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP) calculation approaches. Ensuring an adequate supply of raw materials is crucial for long-term sustainability, maintaining product quality, and managing production costs. Financially, the project yields a positive NPV value (IDR 599,655,405), an IRR exceeding the interest rate (17.9% > 10%), and a relatively short investment payback period (5 years and two months). Based on consideration of the technical and financial aspects, it is evident that the GEM production startup is a feasible and profitable investment.

Abstract

Increased lightning intensity generally causes an increase in the level of hazards such as infrastructure damage and death. To mitigate these hazards, research is necessary. Research developments can be seen from the various literature published in journals or books. This study aimed to quantitatively assess the development of research on lightning protection, grounding systems, and soil resistivity. The bibliometric method is used by searching based on keywords in the Scopus basis data, then visualizing it using VOSviewer. The results showed that the total identified publications were 706 publications all years, the first publication in 1967 and the highest in 2014-2020 with 481 publications (68.1%). The countries that dominate are China and Brazil. Universidade Federal de Minas Gerais was the most productive institution, while Silverio Visacro was the most productive writer. Engineering and energy are the most widely written subjects, while topics related to multidisciplinary are still rare (0.2%). Electric Power Systems Research Journal is the top journal that publishes this research topic. The publication progress map based on co-occurrences consists of 9 clusters. The few research topics include electrical safety, substation, and backfill materials, while current topics include towers, wind turbines, bentonite, natural enhancement materials, and electromagnetic models.
