Abstract

Kec. Cibalong, Kab. Tasikmalaya is 32 km from Siliwangi University and has manganese ore deposits. Kec. Cibalong has smallholder manganese ore mining with the management carried out by local. Two micro and small scale mining companies (UMK), namely the Bara Abadi and Mangan Jaya Companies as partners for community service activities and are local companies that accommodate and facilitate the marketing of people's manganese ore mining products. Both companies have an average of ten workers as miners. During the manganese ore exploration process, it generates residual waste in the form of manganese ore tailings from leaching. Estimates based on information made by the two partners indicate that for every tonne of manganese ore produced, two tonnes of manganese ore tailings are removed. Based on current production levels, it can be estimated that approximately 1,200 tonnes of manganese ore mine tailings are produced annually in Setiawaras Village. These manganese ore tailings are abandoned on roadsides, reservoirs, vacant lots and mining areas. The problems faced by partners are (1) the accumulation of manganese ore mine tailings disturbs and narrows the land for manganese ore mining activities, (2) manganese ore mining tailings causes soil and groundwater pollution, (3) limited knowledge and skills of partners in processing manganese ore tailings products into quality printed roof tiles, (4) limited equipment for the production process of molded bricks from manganese ore mine tailings. The objectives of this program are (1) to increase the added value of manganese ore mining tailings through downstream processing of tailings into molded roof tiles for building materials, (2) to increase the knowledge, insight and skills of the partners group in the manufacture of molded roof tiles without burning from manganese ore mine tailings, and (3) equip production equipment to convert manganese ore mine tailings into molded tile products. The number of participants was 5 members of the Bara Abadi and Mangan Jaya companies in Setiawaras Village. The training was held from 24 to 25 September 2022. This activity is carried out using training, practice, and mentoring methods. The training method is to provide materials on the procedures for making printed roof tiles from a mixture of manganese tailings and plastic waste adhesive. The practical method is carried out by practicing the preparation of fine manganese tailings, adhesive from plastic waste, heating a mixture of manganese tailings and plastic waste using a drum, molding dough with tile molds. The results of the training showed that the participants' interest in this activity was very good, especially for the aspects of tile printing, practicality, and community empowerment. From the aspect of operating activities, it indicated that participants could use and operate the tile printer independently without assistance.

Abstract

The location of the Community Service Program for the Food Security Scheme is in Kec. Kawalu, Tasikmalaya City which is 8 km from Siliwangi University. One of the livelihoods of the residents of Kec. Kawalu is a broiler breeder and has five breeders. The partners of this activity are micro and small breeder companies, namly Sejahtera Mandiri and Maju Bersama and they have been operating for more than two years. The number of employees who are members of the companies of Prosperous Mandiri and Maju breeders together are 4 and 5 people, respectively. In one maintenance period, the business group raises an average of 2000 chicks per cage. The period of rearing chickens until harvest is 30-35 days. During the brooding period (the period when chicks still need brooders or need heating until they are 15 days old), the breeders provide heating facilities with wood/rice husk fuel heaters. Monitoring the cage climate such as temperature and air quality is done manually with conventional temperature and air quality measuring instruments or by observing the activity and distribution of chicks approaching/away from the heater. The problem faced by partners is that there are still many broiler breeders who do not pay attention to the condition of the chickens for monitoring temperature and air quality on a regular basis, causing a high mortality rate of broiler chickens. The purpose of this activity is to increase the knowledge, insight and skills of the broiler breeder community in the district. Kawalu in using automatic control devices and monitoring the temperature and air quality of the cage remotely. The number of participants is 5 people from members of the broiler breeder group UMK Sejahtera Mandiri and Maju together in Lewiliang Village, Kec. Kawalu, the city of Tasikmalaya. The training will be held from 29 to 30 September 2022. This activity is carried out using training, practice, and mentoring methods. The training method is to provide material on procedures for using automatic temperature monitoring control devices and ammonia gas (derived from chicken manure). The practical method is carried out by practicing automatic temperature monitoring tools and ammonia gas. The results of the training showed that the participants' interest in this activity was categorized as very good, especially for the aspect of effectiveness and practicality of broiler chicken coop climate control tools in realizing community empowerment.

Abstract

Distributed photovoltaic (PV) generation has emerged as a key solution for enhancing the performance of medium-voltage (MV) distribution networks, particularly in isolated systems with limited conventional generation. This study investigates the impact of centralized and distributed PV integration on voltage profile and power losses in the 20 kV East Sumba distribution system. A steady-state load flow analysis using the Newton–Raphson method was performed in DIgSILENT PowerFactory under three PV penetration levels (20%, 50%, and 100% of peak load). The base-case condition shows significant undervoltage at remote buses and total active power losses of 474.47 kW, mainly due to long radial feeders and concentrated loading. The results indicate that centralized PV placement yields the strongest voltage recovery near the interconnection point at 100% penetration, whereas the minimum system power loss is achieved at 50% penetration. By contrast, distributed PV placement provides more uniform voltage support across remote buses, although with lower effectiveness in reducing total system losses. These findings reveal a clear operational trade-off between voltage improvement and loss minimization, implying that the preferred PV placement strategy should be selected according to the specific technical objective of the network. This study provides practical insights for planning and optimizing PV integration in weak and isolated MV distribution systems.

Abstract

The mining sector in Indonesia exhibits a disparity between corporate profitability and equity valuation, indicating that non-financial factors may influence investors’ assessments. This study aims to examine the effect of Environmental, Social, and Governance (ESG) disclosure on equity valuation with profitability as a mediating variable. The research sample consists of mining companies listed on the Indonesia Stock Exchange during the 2020–2024 period. A quantitative approach with panel data regression analysis was employed. Data were collected from companies’ annual and sustainability reports and analyzed using EViews software. The results indicate that Environmental and Social Disclosure have no significant effect on equity valuation, while Governance Disclosure has a positive and significant effect. Environmental Disclosure negatively affects profitability, whereas Social and Governance Disclosure positively and significantly influence profitability. Profitability has a positive and significant effect on equity valuation but does not mediate the relationship between ESG disclosure and equity valuation. Simultaneously, ESG disclosure significantly affects both profitability and equity valuation. This study concludes that good corporate governance plays a crucial role in enhancing equity valuation, while environmental and social disclosures require further strengthening to generate optimal financial and market value impacts.
