Abstract

Pematang Johar Village is a village in Labuhan Deli District, Deli Serdang Regency, which has great potential in the social, religious, and economic fields of the community. This study aims to describe the socio-religious conditions and the role of the community in maintaining local religious and cultural values ​​​​amidst the flow of modernization. The research method used is the Participatory Action Research (PAR) method. Where researchers together with the community actively plan and implement the programs carried out. This village is the location of the Community Service Program (KKN) by Uinsu students, who carry out various programs to address social, economic, and educational challenges in the village. The KKN programs implemented include mutual cooperation, religious moderation with socialization of increasing religious values. Empowerment of digital-based MSMEs to increase the marketing of Johar Clean dishwashing soap products. Anti-bullying workshops, legal protection and business in Islam at local elementary schools. In addition, the KKN program also seeks to increase interest in education in the village by holding private tutoring, regular Quranic recitations, and teaching activities at schools.

Abstract

The Electrostatic Precipitator (ESP) is a critical component for particulate emission control in industrial boiler systems. ESP performance is strongly influenced by the condition of discharge electrodes, which are responsible for generating corona discharge and gas ionization processes. During long-term operation, the electrodes are exposed to hot flue gas, moisture, and corrosive compounds from shell combustion, leading to corrosion and surface degradation that may reduce electrical performance. This study aims to analyze the corrosion condition of discharge electrodes in an ESP installed on a 24 ton/h palm-shell-fired boiler and its effect on electrical performance, particularly operating voltage and current. The research employed visual inspection of electrode surfaces, interviews with maintenance personnel, and monitoring of electrical parameters from the transformer–rectifier panel before and after mechanical cleaning and surface coating. A comparative analysis was conducted to evaluate performance changes resulting from electrode maintenance. The results indicate that corroded electrodes significantly decreased secondary current and operational stability of the ESP. After cleaning and coating, the secondary current increased by up to 254%, the conduction angle became more stable, and overall ESP performance improved substantially. These findings demonstrate that corrosion mitigation and periodic electrode maintenance are essential for maintaining ESP electrical reliability and effective particulate emission control in industrial boilers.
