Abstract

This research analyzed the heat rate of a steam turbine in the palm factory of PT. KSA (PT. KSA) using performance testing methods. Steam turbine heat rate is a crucial parameter in power plant efficiency, and optimizing it can lead to significant cost savings. The research methodology conducted performance tests on the steam turbine at KSA's palm factory. The collected data was analyzed to determine the rate of improvement. The efficiency of a steam turbine can be seen from the heat energy input to produce 1 kWh of electricity and the turbine heat rate. Steam turbine efficiency was compared with the fuel energy required for every 1 kWh with the turbine heat rate. The turbine heat rate value was obtained based on the performance test, with the highest value being 51.516 (kJ/kWh) and the lowest being 40.514 (kJ/kWh). For steam turbine efficiency, the highest value was 8.89%, and the lowest value was 6.99%.

Abstract

Steam turbines are widely used at many industrial. The purpose of this research was to study the effect of load capacity on steam flow mass rate.  Load Capacity is directly proportional to the steam flow mass rate to increase Steam turbine power. While the effect of load capacity on steam turbine efficiency, where it shows the actual performance of the steam turbine which is very important to minimize operating costs. The highest thermal efficiency of 21.49% and the lowest thermal efficiency of 20.17% in the load capacity variation showed that the steam turbine can still be categorized in good condition where the operating period has reached 5 years. It is necessary to carry out preventive maintenance on steam turbine components so that they remain reliable in supporting the company's operational and production activities.

Abstract

In Sultan Imanuddin Hospital's central surgical room, analyzing the cooling load is essential to maintaining optimal working conditions for medical procedures. This study aimed to evaluate the efficacy of the cooling system in the surgical room according to the Republic of Indonesia's Minister of Health Regulation Number 7 of 2019. The investigation measured the cooling load required to maintain the room temperature within established health standards. The central surgical room was found to have a cooling load of 4301.462 kcal/h, equivalent to 17059.60 Btu/h. The hospital's air conditioning system, with a capacity of 2 PK or 18000 Btu/h, was determined to be sufficient to handle this load, providing a margin of 940.4 Btu/h. These findings enhance our understanding of the hospital's cooling system and offer recommendations to ensure that patients and medical personnel receive high-quality, safe care.

Abstract

Biomass fuel, recognized for its renewable and environmentally friendly characteristics, presents an attractive option for energy production. This study explores a co-firing system incorporating palm kernel shell (PKS) and coal as fuel feeds for a boiler, aiming to optimize energy production and reduce gas emissions. The influence of co-firing PKS with coal on fuel feed rate and boiler efficiency was analyzed. Boiler efficiency measurements and calculations were conducted using the indirect method. The fuels were co-fired in various ratios: 65:35, 60:40, 55:45, and 50:50 (PKS). The results show that increasing the coal ratio in the fuel blend reduces the fuel feed rate and increases boiler efficiency. The optimized co-firing ratio of PKS to coal was determined to be 60:40, achieving a maximum boiler efficiency of 55.38%.

Abstract

Sand is the most widely used material as a molding material in the metal casting process. Sand can be used as a molding medium if it meets the requirements, including good formability and good permeability. This research was conducted by examining West Kotawaringin local sand by providing several tests, which include a clay content test, a water content test, a formability test, and a permeability test. The test results for local sand showed that the permeability value of sand was 0.001-0.032 cm/sec and the compressive strength value of sand was 0.073-0.126 kg/cm2. These results show that the local sand of West Kotawaringin meets the requirements of molding sand so that it can be used as molding sand in metal casting.

Abstract

In an industrial era that increasingly prioritizes energy efficiency and environmental sustainability, optimizing the use of energy in the production process is crucial. One of the key aspects of achieving this goal is utilizing waste heat to improve the overall efficiency of the system. In this context, the use of economizers has become a major focus in the boiler industry. PT Surya Borneo Industri (SBI), as an industrial entity committed to energy efficiency and environmental sustainability, has adopted the latest technology in a bid to improve the performance of their boiler system. One of the latest innovations they have implemented is the use of rotary soot blowing, an automated device designed to clean the heat exchanger surfaces in the economizer. This study aims to determine the effectiveness value of the economizer before and after the rotary soot blowing treatment on the PT SBI boiler system. Through a series of field observations and data analysis, this research reveals the potential benefits of using rotary soot blowing in improving thermal efficiency, reducing energy losses, and contributing to the sustainability of industrial operations. The results obtained showed that the economizer effectiveness value before the rotary soot blowing treatment was 55, 54, 55, and 54%, and after the rotary soot blowing treatment, the effectiveness value increased to 59, 60, 61, and 60%. This is due to maintenance activities, namely cleaning dust or soot attached to the economizer pipes.

Abstract

Abstract  This study is aimed at seeing some sides of  teacher’s  protection of law, legal traps and an alternative of Progressive Law. From the cases observed, many teachers haven’t known yet the rules concerning with the legal protection for teachers, including of that in the statute number 14 of 2005 about Teacher and Lecturer. Many legal cases happened to teachers, although they’re not serious cases because the purpose is to educate students.  Because parents reported to the law enforcer, the law enforcer was about to handle: to out teachers into jail. The implementation of Positive Law is likely ‘black-and-white’ or less of considering the aspects of humanity. As an effort to manage teachers’ legal cases, Progressive Law becomes an alternative to enforce the law based on, to borrow Prof. Satjipto Rahardjo’s terminology, the master of Sociology of Law and a pioneer of Progressive Law, senses of humanity and happiness together. Deconstructing the humanity-oriented legal thinking becomes the focus of the study so that teachers are not tied by legal traps that shadow them in the teaching-learning processes. Key-words: deconstruction, teacher, protection, Progressive Law

Abstract

This study aims to analyze the implementation of transformational leadership strategies in developing life skills training programs for Paket C students at PKBM Suka Madju. Using a qualitative case study approach, data were collected through in-depth interviews, observations, and document analysis to explore leadership dynamics and their impact on educational outcomes. The novelty of this study lies in examining transformational leadership within nonformal education, an area that has received limited attention compared to its application in formal education institutions. The findings indicate that transformational leadership significantly enhances program effectiveness by increasing student participation, aligning the curriculum with labor market needs, and integrating interactive, technology-based teaching methods. However, several challenges remain, including limited financial resources, low student motivation, and insufficient public awareness of the importance of nonformal education. To address these issues, PKBM Suka Madju continues to strengthen its institutional management, improve teacher development programs, and expand partnerships with industry and government agencies. The study highlights the need for sustained leadership development and collaboration to ensure the long-term success of life skills training programs in nonformal education. Keywords: Transformational leadership, life skills training, nonformal education, Paket C, PKBM Suka Madju.
