Abstract

Alignment is a process that aligns two shaft axes that are not straight to centric (between the driving shaft and the driving shaft axis). Correct alignment is needed so that checks are completed on the correct clutch, so that offset misalignment and angle misalignment do not occur again which results in damage to machine components which is detrimental to the industry. Misalignment is a condition where there is a deviation at the point between two connected axes (two axes are not located on the same axis). If misalignment occurs in the clutch, it will accelerate damage to the clutch, bearings and other components, and cause excessive vibration. The purpose of writing this report is to find out the basic theory of alignment and find out the alignment method using the laser method.

Abstract

This study aims to investigate how stakeholders, including palm oil enterprises, smallholder cooperatives, banking institutions, and regulators, perceive the role of banking support in facilitating or hindering the adoption of digital accounting systems. This study employs a qualitative exploratory design to capture the diverse perspectives of stakeholders on the role of banking support in facilitating digital accounting adoption within the palm oil industry. A purposive sampling strategy will be employed to ensure participants possess direct experience with either banking support or digital accounting adoption. Data will be analyzed using thematic analysis. Interview transcripts, focus group notes, and documents will be coded inductively and deductively, guided by the research questions. The findings reveal that banks are not merely providers of financial capital but also act as institutional gatekeepers that shape reporting practices and encourage digital transformation. Larger enterprises view digital accounting as a strategic tool for efficiency and compliance, while smallholders often see it as a burdensome requirement.

Abstract

Optimalisasi Key Performance Indicators (KPI) pada pembangkit listrik turbin uap sangat penting untuk meningkatkan efisiensi operasional dalam industry pengolahan kelapa sawit. Penelitian ini menerapkan metode Analytic Hieararchy Process (AHP) untuk menentukan bobot relative setiap KPI, sehingga memfasilitasi pengambilan keputusan berbasis data untuk peningkatan kinerja. Empat KPI krusial dievaluasi melalui perbandingan berpasangan berdasarkan keahlian para pakar. Hasil penelitian menunjukkan bahwa power output (47,16%) merupakan KPI paling signifikan, diikuti oleh availability factor (38,58%), steam consumption (9,69%), dan capacity factor (4,58%). Nilai consistency ratio (CR) dari seluruh penilaian pakar berada di bawah 0,10, yang menunjukan bahwa hasil AHP tersebut dapat diandalkan.

Abstract

This paper presents the design and implementation of TOF (Tool Open Fan) as an innovative solution to enhance the maintenance efficiency of exhaust fans in gland steam condensers (GSC) at coal-fired steam power plants. Conventional disassembly using puller tools often caused mechanical damage to the fan surface, leading to costly replacements and downtime of up to 38 days. The TOF tool was designed with an adjustable house, fix house, and jack bolt mechanism to provide safe, ergonomic, and efficient fan disassembly. Finite element simulations were conducted to analyze stress distribution on both the tool and the fan. Implementation at PLTU Tenayan demonstrated a significant reduction in maintenance duration, from 9 hours to 3 minutes, and reduced manpower from five to two workers. Financially, the innovation generated a saving of approximately IDR 104,500,000 per exhaust fan by avoiding unnecessary replacement. The study concludes that TOF offers both economic and safety benefits, contributing to power plant reliability and sustainable maintenance practices. Limitations include the need for further design adjustments for compatibility with different GSC configurations across power plants.

Abstract

This study evaluates the co-firing of palm oil industry waste biomass, specifically Palm Kernel Shell (PKS) and Empty Fruit Bunch (EFB) pellets, in coal-fired power plants (PLTU) in Riau, Indonesia, to support a sustainable energy transition. Empirical tests were conducted at PLTU Tenayan and Tembilahan, using biomass substitution rates of 5% and 50%, respectively. Key performance indicators, including Specific Fuel Consumption (SFC), Net Plant Heat Rate (NPHR), production cost, and exhaust emissions (SO₂ and NOₓ), were analyzed. Results show that 5% PKS co-firing at PLTU Tenayan reduced SFC from 0.871 to 0.856 kg/kWh and NPHR from 4,187 to 4,116 kCal/kWh, while 50% PKS co-firing at PLTU Tembilahan decreased SFC from 1.171 to 0.785 kg/kWh and NPHR from 5,312 to 3,625 kCal/kWh. Economically, PKS co-firing resulted in cost savings of up to Rp223.58/kWh. Emission measurements revealed SO₂ reductions up to 27.8% at PLTU Tenayan and 34% at PLTU Tembilahan (EFB scenario), with NOₓ emissions remaining stable or decreasing by up to 13%. Conversely, EFB pellet co-firing increased fuel consumption and production costs due to higher fuel prices and operational challenges. The study confirms that PKS co-firing is a viable and effective approach to enhance power plant efficiency, reduce emissions, and lower costs in palm oil-producing regions. Limitations include short test durations and limited plant sites; therefore, long-term monitoring is recommended to assess boiler integrity, operational stability, and emission performance for sustainable large-scale implementation. This research provides critical technical, economic, and environmental insights for advancing biomass co-firing in commercial coal power plants.
