Abstract

Increasing energy efficiency in the cement production process at PT Semen Padang is carried out by reusing exhaust gas to produce electricity using Waste heat recovery power generation (WHRPG) with a capacity of 8.5 MW. WHRPG is a technology for utilizing exhaust gas heat as a source of heat energy to heat feed water into steam by using a suspension preheater (SP) boiler and air quenching cooler (AQC) boiler. This study aims to calculate the power potential of the steam heat influenced by the steam temperature and the mass flow rate of the steam produced by the boiler, to calculate the efficiency of the boiler using the direct method by comparing the boiler output heat against the boiler input heat, to calculate the turbine efficiency based on the difference between the steam enthalpy enter the turbine against the steam enthalpy out of the turbine and the isotropic enthalpy of the steam out of the turbine and to calculate the power generated by WHRPG at PT Semen Padang. The results obtained in this study are the total potential power of steam heat is 19.778 MW, the boiler AQC efficiency is 70.30%, the boiler SP efficiency is 94.04% and the turbine efficiency is 78.64%. The electricity generated by PT Semen Padang's WHRPG is 3.70 MW.

Abstract

Leakage current measurements can be used to determine the aging condition of the ZnO arrester. The leakage current that occurs in the arrester is divided into two, namely external and internal leakage currents. The external leakage current is affected by contamination and the internal leakage current is affected by the aging of the varistor in the arrester. The external and internal leakage currents are measured separately to determine their contribution to the arrester condition. In this study, the effect of salt contamination on the arrester was studied further. The level of contamination used consisted of low, medium and heavy. The obtained leakage current is analyzed using wavelet energy. The results of this study indicate that the wavelet energy of each leakage current is different and can be used as an indicator in further analysis. The conclusion obtained is that the external leakage current is affected by contamination and has a different energy with the internal leakage current due to aging of the varistor arrester components.

Abstract

Biocomposite strain sensors must enhance their electrical properties and understand the impact of humidity on these properties. This study aimed to enhance the current density and specific capacitance of polyvinyl alcohol (PVA) and polypyrrole (Ppy) composite materials for strain sensors. The materials were prepared by blending polyvinyl alcohol and polypyrrole, followed by magnetic stirring, drying, and stretching. Current density and specific capacitance measurements were taken before and after the stretching process and at three distinct relative humidity levels (50%, 75%, and 93%). After the tensile test, the results indicated a significant increase in current density by 128.46% and a corresponding rise in specific capacitance by 112.57%. Furthermore, with an increase in relative humidity from 50% to 75%, current density and specific capacitance exhibited remarkable growth of 445.95% and 899.44%, respectively. The subsequent shift from 75% to 93% relative humidity resulted in a comparatively lower percentage increase in current density and specific capacitance at 22.59% and 10.29%, respectively, due to a decrease in hydroxyl bonds. These findings align with the material's characteristic tests, confirming that the improved electrical properties can be attributed to a more uniform distribution of polypyrrole during the stretching process and increased hydroxyl bonds associated with higher humidity levels. As electrical properties increase, the sensor's sensitivity will also rise.

Abstract

Wawasan kebangsaan merupakan salah satu ilmu yang wajib dipupuk dan di tanamkan dalam diri remaja, terutama kalangan pelajar, mulai dari lingkup pelajar Menengah Pertama maupun Menengah Atas. Saat ini sumber penanaman wawasan kebangsaan dalam lingkup pelajar umumnya hanya bersumber dari mata pelajaran PPKn, namun hakikatnya instansi pendidikan harus menanamkan nilai nilai wawasan kebangsaan dalam sebuah peraturan sekolah. Dengan ini maka perlu diadakan penelitian guna mengetahui seberapa jauh tingkat pemahaman pelajar tentang wawasan kebangsaan dan implementasinya dalam aturan sekolah. Penelitian ini menggunakan metode kualitatif serta pengumpulan data menggunakan teknik kuisioner yang ditujukan pada pelajar menegah pertama dan menengah atas. Hasil dari penelitian ini diketahui konsepsi tingkat pemahaman pelajar cukup baik untuk memahami wawasan kebangsaan dengan menyertakan contoh implementasi di lingkup sekolah. Media yang digunakan pelajar mayoritas mendapatkan pemahaman wawasan kebangsaan melalui pelajaran PPKn di sekolah, tetapi ada juga yang melalui media lain seperti belajar otodidak, kehidupan sehari-hari, mempelajari sejarah bangsa, dan media informasi digital. Pelajar memahami penerapan wawasan kebangsaan yang berdamping dengan kewajiban pelajar dengan mengikuti kegiatan wajib di sekolah. Pelajar paham bagaimana cara implementasi wawasan kebangsaan dengan sikap nasionalisme.

Abstract

Happiness is important in maintaining the stability of human resources, including in the educational sector. However, studies on happiness at work are still neglected. In the organizational scale, the discussion on happiness is compelling as it relates to work achievement or productivity. Moreover, studies on factors affecting happiness at work are still limited, especially in teachers who work under the auspices of Muhammadiyah. The present study determines the influence of work passion, servant leadership, and perceived organizational support on teachers' levels of happiness in the workplace. The study used quantitative research with a correlation method. The research population is the teachers of 54 Muhammadiyah schools in Yogyakarta. The sample was determined using proportional cluster random sampling with 28 schools and 263 teachers. The instruments evaluated were work passion (α=0.975), servant leadership (α=0.952), perceived organizational support (α=0.869), and happiness at work scales (α=0.877). The data were analyzed using multiple regression analysis. The results showed that work passion, perceived organizational support, and servant leadership influence Muhammadiyah teachers' happiness at work in Yogyakarta. The teachers' personal factors (work passion) and organizational factors (principal leadership style) at work are essential to pay attention to in order to increase teachers' happiness.
