Abstract

This study presents the design results of a Vertical Pressure Filter based on Pulse Width Modulation (PWM) using a linear actuator for the separation process of nickel laterite slurry. The development of this system is motivated by the limitations of conventional filtration systems that still use fixed pressure and are less flexible in regulating filtration pressure. The research method used is Design and Development (DD), which includes the design of mechanical and electronic systems, development of PWM control circuits, prototype realization, and system performance testing. Tests were carried out on variations of PWM duty cycles of 20%, 40%, 60%, 80%, and 100% to evaluate the actuator response and filtration performance. The results show that increasing the PWM duty cycle increases the actuator speed and vertical pressure in the filtration chamber. The duty cycle range of 20%–40% provides a more stable actuator response with low vibration and is suitable for the nickel laterite slurry filtration process. In addition, the system was able to produce a filtrate efficiency of 3.76% and a residue efficiency of 76.7%, which indicates the ability to form a filter cake and retain solids in the filtration media. The results of the study indicate that the PWM-based Vertical Pressure Filter has the potential as an adaptive, simple, and flexible filtration system for laboratory and pilot plant applications in nickel laterite processing.

Abstract

Modifikasi geometri pelat absorber merupakan salah satu pendekatan strategis untuk meningkatkan perpindahan panas pada kolektor surya, namun kajian eksperimental yang membandingkan secara langsung pengaruh bentuk gelombang segi empat dan setengah lingkaran terhadap kinerja sistem pengering jagung masih sangat terbatas. Penelitian ini bertujuan menganalisis pengaruh geometri pelat absorber bergelombang segi empat dan setengah lingkaran terhadap kinerja termal kolektor dan performa pengeringan jagung menggunakan metode eksperimental langsung (direct experimental method) di bawah kondisi radiasi matahari alami. Pengujian dilakukan terhadap 6 kg jagung dengan kadar air awal 25,5% (basis basah) selama 360 menit, dengan interval pengamatan setiap 45 menit. Parameter yang dianalisis meliputi penurunan kadar air, kecepatan udara, laju aliran massa udara (ṁa), energi panas berguna (QU), dan efisiensi termal kolektor (ηth). Efisiensi termal tertinggi dicapai pada interval pengeringan menit ke-225, yaitu sebesar 39,8% untuk pelat segi empat dan 32% untuk pelat setengah lingkaran. Hasil menunjukkan bahwa pelat absorber segi empat memberikan kinerja lebih baik dibandingkan setengah lingkaran: kadar air akhir yang dicapai sebesar 9,2% berbanding 10,8%; kecepatan udara maksimum masing-masing 0,9 m/s dan 0,8 m/s. Peningkatan performa ini dipengaruhi oleh luas permukaan efektif yang lebih besar serta turbulensi aliran yang lebih tinggi pada geometri segi empat, sehingga optimasi geometri absorber terbukti meningkatkan efektivitas sistem pengering surya.

Abstract

Coconut coir is an abundant by-product of coconut processing that remains underutilized, particularly in Bahodopi District, Morowali Regency. Coir chopping is still carried out manually, which is time- and labor-intensive and produces uneven results. This study aims to design and build a robust, easy-to-operate coconut coir chopping machine capable of efficiently converting coir into cocofiber. The engineering method was applied, comprising literature study, design using SolidWorks, frame strength simulation, material selection, assembly, and testing. The machine is driven by a three-phase induction motor (1400 rpm, 50 Hz) equipped with an inverter, allowing the blade rotation speed to be varied at 15, 30, and 50 Hz. Testing used approximately 3 kg of dry coir for each variation. The results show that the machine can chop coir at a capacity of 180 kg/hour, with the best result—fine and even—obtained at 30 Hz. Static simulation of the frame under an 800 kgf load produced a maximum stress of 374.421 MPa and a minimum safety factor of 0.939, indicating the need to reinforce the critical points of the frame. This machine is expected to help the Bahodopi community process coir more easily and to create new economic opportunities

Abstract

A jet bubble column is a reactor used in various process fields that functions to produce a strong liquid flow and expand the contact area between gases, liquids, and solids. However, research studies on the application of jet bubble columns for industrial wastewater treatment processes are still relatively limited. This study aims to modify the jet bubble column so that it can reduce the levels of heavy metals in industrial liquid waste. The tool is modified by adding granular adsorbents to the inside of the column which are held on a perforated plate holder. The tools and materials used include 5-inch PVC pipes, ½-inch PVC pipes, pipe fittings, pipe caps, hollow iron, DC pumps, valves, and brass nozzles. The jet bubble column tool has a fluid volume capacity of 5 L, a jet pump with a maximum pressure of 90 bar, a fluid flow rate of 7 L/minute, and a process time of 30 minutes. The test results show that the jet bubble column is able to reduce the levels of hexavalent heavy metals in industrial liquid waste by up to 83.67% with a contact time of 30 minutes. This shows better performance compared to the use of commonly used mechanical stirring.
