Abstract

Pada sistem distribusi tenaga listrik terdapat penyulang tegangan menengah yang berguna untuk mendistribusikan tenaga listrik dari gardu induk ke konsumen. Tetapi tidak terlepas dari masalah, masih terdapat gangguan yang perlu dianalisa, diantaranya gangguan hubung singkat. Untuk melokalisasi gangguan tersebut diperlukan sistem proteksi yang memenuhi persyaratan sensitifitas, keandalan, selektifitas dan kecepatan. Peralatan proteksi yang sering digunakan pada sistem distribusi adalah over current relay (OCR) dan ground fault relay (GFR), yaitu relai yang berfungsi memberi perintah PMT untuk membuka, sehingga saluran yang terganggu dipisahkan dari jaringan. Di dalam penelitian ini studi kasus di ambil di PLN Gardu Induk Jababeka pada penyulang Rambutan dimana selektifitas kerja relai diambil dari empat titik gangguan pada penyulang. Semua dilakukan untuk peningkatan kerja relai. Pada Tugas Akhir ini akan membahas mengenai perbandingan antara setting relai proteksi hasil dari perhitungan dengan setting proteksi yang terpasang (existing) pada jaringan distribusi 20 kV GI Jababeka di penyulang Rambutan.

Abstract

Ampas tahu adalah salah satu bahan yang bisa dipakai sebagai bahan penyusun ransum. Sampai saat ini ampas tahu cukup mudah didapat dengan harga murah, bahkan bisa didapat dengan cara cuma-cuma. Ditinjau dari komposisi kimianya ampas tahu bisa digunakan sebagai sumber protein. Mengingat kandungan protein dan lemak pada ampas tahu yang cukup tinggi. Namun kandungan tersebut berbeda tiap tempat dan cara pemprosesannya. Terdapat laporan bahwa kandungan ampas tahu yaitu protein 8,66% lemak 3,79% air 51,63% dan abu 1,21%, maka sangat memungkinkan ampas tahu dapat diolah menjadi bahan makanan ternak. Maka pada perancangan Tugas Akhir (TA) DIII Teknik Mesin Produksi akan mencoba membuat alat/mesin dengan judul ?Rancang Bangun Mesin Pencetak Pelet Dari Bahan Ampas Tahu Dilengkapi Dengan Pengering?. Diharapkan dengan adanya mesin tersebut, sangat membantu peternak dalam memudahkan dan mempercepat pembuatan Pelet untuk pakan ternak mereka, dan menjadikan Ampas Tahu menjadi komoditi yang sangat menguntungkan dan bernilai jual tinggi, disamping itu pengolahanya pun sangat mudah.Tahap perancangan mesin pencetak pelet dari bahan ampas tahu dilengkapi dengan pengering ini adalah desain dan gambar kerja dari setiap bagian-bagian alat/mesin ini.

Abstract

Musicool is an alternative refrigerant developed as a working fluid in a steam compression refrigeration system. Musicool has many advantages compared to conventional refrigerants, the advantage is that it is environmentally friendly. This study aims to determine the characteristics of musicool 134 on a steam compression refrigeration machine using a double evaporator. The test is done by comparing the characteristics of a single evaporator refrigeration machine and a double evaporator using musicool 134. The research variable is the air flow through the evaporator that is equal to 0.022 kg / s, 0.027 kg / s, 0.033 kg / s. The test data is taken by measuring the temperature and pressure of each component in the refrigeration machine, then using the P-h diagram musicool 134, to determine the performance of the refrigeration machine. The results of the study provide information that the use of a double evaporator will give rise to an improved refrigeration system performance compared to using a single evaporator.

Abstract

In the digital age, the emergence of social media has transformed the operational landscape of small and medium enterprises (SMEs). Recognized as a tool that generates comprehensive insights, social media analytics supports strategic decision-making. However, the concrete impact of social media analytics on strategic decisions in SMEs still requires further exploration. This study aims to assess the impact of social media analytics on strategic decision-making in SMEs, considering mediating variables such as organizational innovation and adaptability. Employing Structural Equation Modeling (SEM) with SmartPLS 4.1 software, the study analyzed data collected from 200 SMEs actively using social media for operations and marketing. The findings reveal that social media analytics significantly enhances organizational innovation and adaptability, which in turn positively affects strategic decision-making. This analysis underscores the importance of social media as a strategic resource in a dynamic business environment. The study provides valuable insights for SME owners on the critical role of social media analytics in enhancing strategic decisions. Theoretically, it extends the literature on social media analytics and strategic management within the SME context. Practically, the results serve as a foundation for SMEs to integrate social media analytics technology into their decision-making processes, thereby boosting adaptability and innovation in their operations.

Abstract

This study examines the influence of corporate governance and firm size on tax avoidance among manufacturing companies listed on the Indonesia Stock Exchange from 2016 to 2019. Using a sample of 10 companies selected through purposive sampling, the research employed multiple linear regression analysis. The findings reveal that neither corporate governance nor firm size significantly impact tax avoidance, with significance levels of 0.669 and 0.069, respectively. These results suggest that these factors do not play a crucial role in tax avoidance strategies in the examined companies, providing insights for policymakers and stakeholders in understanding tax planning behaviors. Highlights: 1. No significant impact of corporate governance on tax avoidance.2. Firm size non-influential on tax avoidance strategies.3. Limited role of these factors in Indonesian manufacturing firms. Keywords: tax avoidance, corporate governance, firm size, multiple linear regression, Indonesia Stock Exchange

Abstract

This study aimed to determine the effect of the frequency of vitamin E application on the reproductive performance of postpartum FH crossbreed cows, which Include Post Partus Estrous (first estrus after calving) and Post Partus Mating (first mating after calving). The study used treatment giving vitamin E to cows after calving with treatment 0 (P0)/control, treatment 1 (P1) was injected on the 7th and 14th days after calving and treatment 2 (P2) was injected on the 7th day, the 14th day after calving and 17th day after calving. Post Partus Estrous (PPE) and Post Partus Mating (PPM) were the treatment variables observed. Giving vitamin E on the 7th, 14th, and 17th days after calving (P2) showed a very significant effect (P<0.01) on Post Partum Estrous (PPE). The results of ANOVA analysis of treatment 2 (P2) days 7, 14, and 17 after calving showed a very significant effect (P<0.01) on Post Partus Mating (PPM). This study shows that the P2 treatment with vitamin E injection on days 7, 14, and 17 after calving obtained the best reproductive performance by producing the shortest Post-Partus Estrus (PPE) of 51 days and the shortest Post-Partus Mating (PPM) of 71.83 days.

Abstract

The covid-19 pandemic has caused PT. Bintang Inti Karya experienced a decrease in income, so the company made a unilateral salary deduction for workers because they were unable to pay workers' salaries as usual. The existence of unilateral salary deductions causes rights disputes between employers and workers. This study uses a normative research method with a statutory and conceptual approach. The results showed that the work agreement at PT. Bintang Inti Karya which is actually a standard agreement, substantially there are still several weaknesses that make the work agreement less than ideal to be used as a basis for carrying out work relations, especially related to dispute resolution. In addition, the work agreement is not in accordance with the principle of freedom of contract because the making of the work agreement does not involve the workers in determining the contents of the agreement. Unilateral salary deductions based on Article 1365 of the Civil Code can be categorized as a form of unlawful act, where the act is not in accordance with the principles of the agreement, namely the principles of pacta sunt servanda, good faith, balance and propriety. Departing from these problems, it is necessary to construct an ideal work agreement as the basis for carrying out an employment relationship. All provisions regarding the rights and obligations of the parties in an employment relationship must be clearly and completely contained in the employment agreement. In addition to referring to the terms and conditions contained in Article 55 paragraph (1) of the Labour Act, a work agreement must contain provisions related to force majeure as well as the mechanism and legal domicile of dispute resolution in order to realize the construction of an ideal work agreement. Keywords: Employment Agreement, Unlawful Acts, Construction.
