Abstract

Kacang tanah merupakan produk holtikultura yang memiliki kandungan nutrisi yang tinggi, namun kacang tanah bersifat semi perishable sehingga memiliki umur simpan yang tidak lama. Kandungan air yang tinggi yang ada pada kacang tanah dapat dikurangi dengan pengeringan. Metode pengeringan menggunakan mesin pengering tipe rak horizontal mampu mengoptimalkan proses pengeringan khususnya pada benih karena dapat dilakukan pada waktu yang diinginkan sehingga kacang tanah dapat memiliki umur simpan yang lebih panjang. Tujuan penelitian ini adalah untuk mengetahui pengaruh mesin pengering tipe rak horizontal terhadap karakteristik pengeringan benih kacang tanah berupa kadar air, laju pengeringan serta perbedaan suhu, kelembapan dan lama waktu pengeringan. Metode penelitian yang dilakukan yaitu dengan menggunakan mesin pengering tipe rak dengan memanfaatkan prinsip kerja dari mesin MSSD (Multi Seed Smart Drayer) dan dilakaukan pengukuran kadar air awal menggunakan metode gravimetri. Data perubahan massa benih kemudian dianalisis sehingga didapatkan data penurunan kadar air, laju pengeringan. Data suhu dan kelembapan didapat dari data logger. Berdasarkan analisis yang telah dilakukan, nilai karakteristik pengeringan biji kacang tanah serta perubahan suhu dan kelembapan menunjukkan perbedaan nilai pada setiap rak. Setelah dilakukan pengeringan selama 6 jam, kadar air awal benih kacang tanah yang bernilai 23,80% berkurang dengan nilai 17,20%.

Abstract

Multiphase flow channel is commonly applied in various industrial contexts, including lab-on-a-chip, nuclear power plants, microelectronics cooling systems, and chemical microreactors. Equipment ranging from mini to micro sizes plays a vital role in enhancing heat and mass transfer processes during the mixing of two or more phases. Non-uniform phase distribution during the passage of a two-phase flow through a T-junction can cause performance issues in the downstream region. A problem arising from the use of T-junctions is the occurrence of slugs. An experimental study was conducted to investigate the effect of varying bend radius on the flow characteristics in the downstream region of a T-junction minichannel, such as slug velocity and frequency. The slug velocity was researched in the downstream region of the horizontal minichannel T-junction. The working fluid used was air as the gas phase and water. The findings indicate that there is a linear relationship between the superficial velocities of air and water and the corresponding slug velocity in the downstream area of the horizontal minichannel T-junction, as observed through the utilization of a high-speed camera and MATLAB program for image processing. It has been observed that the local velocity within the channel increases as the corner radii increase towards the downstream region.

Abstract

This research aims to test the effect of Environmental, Social, and Governance (ESG) proxied by ESG Risk Rating on tax avoidance. This study also examines the influence of leverage measured by the Debt-to-Assets Ratio (DAR) on tax avoidance. Moreover, this research also examines the effect of financial per-formance as sized by the Return on Assets Ratio (ROA) on tax avoidance. This study uses quantitative descriptive research and panel data analysis to scrutinize data from companies listed in the ESG Leaders Index over three years from 2020 to 2022. The research used eViews 12 software to analyze a descriptive-quan-titative panel data regression analysis to evaluate the research hypotheses. The result showed that imple-menting ESG can reduce tax avoidance and create better financial performance. However, leverage is proven to reduce tax avoidance, but does not influence financial performance. This research concludes that tax avoidance isn’t affected by financial performance but is more influenced by management be-havior. Moreover, financial performance does not mediate the relationship between ESG, leverage, and tax avoidance. These findings underscore the importance of integrating sustainability principles into cor-porate governance to mitigate tax avoidance behaviors and promote fiscal transparency.

Abstract

Tourism, as an economic sector with significant potential, requires attractions that can be drawn from various aspects, including icons. These icons, rooted in local characteristics and culture, can be transformed into statues, monuments, and other forms of representation. However, sculpture creation poses a challenge for communities lacking adequate knowledge and skills. Natural fibers, such as bamboo, hemp, tree bark, rattan, and straw, are abundant materials that can be utilized for this purpose. Trangsan Village in Sukoharjo Regency, Central Java, is one area with tourism potential that currently lacks icons and branding. This research aims to develop methods for creating sculpture or tourism icons by translating 3D software models into life-sized objects or prototypes. The research stages include observation and data analysis, determination of tourism icons, 3D modeling, and post-modeling by composing fragment images as anatomical references. The subsequent processes involve creating and materializing prototypes, protecting intellectual property rights, and conducting public tests. This study addresses the challenge of icon creation in underdeveloped tourism areas and offers a systematic approach for integrating traditional craftsmanship with modern technology to enhance local tourism branding.

Abstract

Fire is one of the disasters that can cause significant losses, both material and nonmaterial. To reduce this risk, an automated system is needed that can respond quickly to fires. This robot is designed and built to automatically detect and extinguish fires using the Sugeno fuzzy logic method based on an Arduino microcontroller. The robot system is equipped with a flame sensor to detect the presence of fire and an ultrasonic sensor for obstacle avoidance navigation. The Sugeno fuzzy logic method is used to control the robot's movement decisions based on data received from the sensors, enabling the robot to move adaptively toward the fire source. Once the fire's location is detected, the robot activates a fan as an actuator to extinguish the fire. System testing was conducted by observing the robot's response to the presence of fire, including its ability to detect and extinguish small fires from candles in a short time, as well as navigate obstacles effectively. With this system, it is hoped that it can serve as an initial solution for automatically and efficiently addressing minor fires. Keywords: firefighting robot, Arduino, Sugeno fuzzy logic, flame sensor, automation.

Abstract

Kabupaten Jember memiliki potensi besar di sektor pertanian, namun kendala utama yang dihadapi petani adalah tingginya harga pupuk. Di sisi lain, Kecamatan Puger memiliki PT Pertama Mina Sutra Perkasa, perusahaan penambangan batugamping yang menghasilkan limbah berupa apal dan debu halus yang belum dimanfaatkan optimal. Batugamping mengandung kalsium dan magnesium yang penting bagi pertumbuhan tanaman dan kesuburan tanah, sehingga berpotensi dijadikan bahan campuran pupuk organik. Penelitian ini bertujuan untuk memanfaatkan sisa hasil tambang batugamping sebagai bahan dasar pupuk organik yang ramah lingkungan dan bernilai ekonomi. Proses pembuatan pupuk dilakukan dengan tiga proporsi bahan: (1) 60% batugamping, 20% batufosfat, dan 20% tetes tebu serta urine kambing; (2) 25% batugamping, 25% batufosfat, dan 50% kotoran kambing fermentasi; serta (3) 10% batugamping, 10% batufosfat, dan 80% kotoran kambing fermentasi. Hasil analisis menunjukkan bahwa proporsi ketiga memberikan nilai C-organik tertinggi yaitu 6,92% serta peningkatan kandungan hara makro seperti nitrogen (N), fosfor (P₂O₅), dan kalium (K₂O). Batugamping berperan penting dalam meningkatkan pH dan kandungan kalsium pupuk, sedangkan kotoran kambing menambah unsur organik dan nitrogen. Meskipun belum sepenuhnya memenuhi standar SNI 7763:2018, hasil penelitian ini menunjukkan potensi besar dalam pengembangan pupuk organik berbasis limbah tambang demi mendukung pertanian berkelanjutan.

Abstract

This study aims to analyze the financial feasibility and operational impact of investment in a Groove Roller Pressure Feeder (GRPF) at PG Trangkil, a private sugar factory in Central Java, Indonesia, as an effort to increase milling efficiency and reduce production costs amid intensifying competition from newly built, higher-efficiency sugar mills. A mixed-method case study design was employed, combining qualitative data from in-depth interviews, non-participant observation, and company archives with quantitative capital budgeting analysis (NPV, IRR, Profitability Index, Payback Period, and ROI). Key informants were the factory manager and heads of the technical, finance-administration, and manufacturing divisions, selected purposively. Results show that the GRPF investment, valued at IDR 25 billion, generated an NPV of IDR 876,997,000, an IRR of 11.19 percent, a Profitability Index of 1.04, and a payback period of 4.21 years, and is therefore financially feasible. Operationally, GRPF raised mill extraction and reduced sucrose loss in bagasse, lifting sugar sales revenue by 111.16 percent and net profit by 22.59 percent, although rising raw-material costs compressed gross and net profit margins. The findings extend a mini-theory linking integrated investment planning to milling efficiency and financial performance in the private sugar industry.
