Abstract

The efforts to increase capacity while maintaining the granulation of the grinding process are carried out to maximize the use of the hammer mill machine, which is the second largest electric energy consumption in a plant. The method that can be done to achieve this is by setting the screen position and setting the right blower opening. Standard screen specifications will maximize the capacity of the grinding process and produce optimum granulation. In order to get the maximum grinding capacity, DFCO can be set at the maximum but will have an effect on the motor current during the grinding process, the average current will tend to be high. The aim of this research was to determine the effect of variations in the screen’s and blower’s position settings on the capacity and granulation of raw materials from the grinding process. The usage of 2.5 mm and 3 mm diameters screens, as well as adjusting the screen position of 2.5 mm at the top and 3 mm at the bottom, resulted in better capacity and granulation than using a screen with only 3 mm diameter. The larger the blower and DFCO openings, the greater the grinding capacity, but also increased the motor current. The larger the blower opening, the greater the decrease in the water content of grinding raw materials.

Abstract

The braking process is the basis in the making of the PWM speed control system in order for electric cars to be able to stop automatically and increase the driving safety. The usage of an electric motor as a wheel drive for an electric car allows controlling with a microcontroller. Based on the journal about electric motor control, it is necessary to study the use of PWM as a speed controller. The C language as a coding language can be understood by the Arduino microcontroller with the aim of regulating the speed of the electric motor. The research objective was to use the C language programming as a PWM speed controller with the Arduino microcontroller. The methodology used in this study was to modify a remote control car (RC) made as a prototype electric car. The Arduino microcontroller system was installed and programmed in C language as a PWM speed controller. The main sensor tool used was the ultrasonic distance sensor as the microcontroller input data. Direct current (DC) motors on RC cars were regulated with a pulse width modulation (PWM) signal as the output from the Arduino. LCD and buzzer were used as display devices and indicators of safe distances between prototypes and obstructions. The test results showed that the detection distance of the ultrasonic sensor reached 2 cm to 500 meters. Then the acceleration data obtained by pulse width modulation 64 at 1 meter distance, 127 at 3 meter distance, 191 at 4 meter distance, 225 at 5 meter distance and was made in graphic form. In a speed control system, the usage of the Arduino UNO microcontroller was easy to apply and had complete features. The series of speed control systems could be applied to electric cars with the PWM slow reduction criteria in two stages. The PWM lowering process took 1 second after the sensor detects an obstruction object.

Abstract

The challenge of a CNC Router is the dust and small particles produced during the cutting process such as wood, aluminum or acrylic materials. These small particles can disturb the health of operators. 3D printing is a technology where materials are arranged layer by layer to produce three-dimensional products. PETG filament is a type of polymer that has a density of 1.38 g/cm3 and has the advantage of being weather resistant, not being damaged or losing color when exposed to UV light. PETG filament uses a printing temperature of 230°C-265°C. This bracket is designed to hold hoses and dust collector. The Bracket design can be installed on a CNC router machine without interrupting the cutting process or reducing the quality of the final result. The method used is Autodesk Inventor Professional 2023 student edition software for 3D design and UltiMaker Cura for the slicing process. This research resulted in a bracket design and prototype using a 3D printer. The bracket exhibits sufficient structural capability to hold the cooling hose and dust collector. There is a dimensional difference between the design measurements and the workpiece that has been made of 0.27 mm in the CNC Router head diameter and 0.1 mm in the hose diameter. This is due to the work tolerances and parameters used on the 3D printer machine. By implementing the Hose and Dust Collector Bracket, it is hoped that small particles can be reduced so that a clean and dust-free work environment can improve operator health and comfort.

Abstract

Pump units with a Caterpillar C27 engine with an EUI (Electronic Unit Injector) fuel system that often has low power due to filter clogging at PT. Sapta Indra Sejati. Filter cloggingoccurs due to due to the thickened biofuel content and creates a crust. If the machine has a problem, the mining process can be disrupted because the coal loading area is flooded. This study aims to create an additional system in the form of a automatic semi-returnless where the fuel return line is changed automatically into the filter because the fuel return is clean. The movement of the return control valve is regulated by a microcontroller which is programmed according to specifications and needs. The microcontroller used is Arduino Unowith pressure and temperature sensors. Arduino Uno is programmed when the engine will experience low power with a fuel pressure of 400 kPa then the return path is changed to semi returnless. With a change in the semi returnless path, the pressure becomes stable at 380 kPa and the engine RPM is stable with power that is still maintained. The advantages of semi-returnless system are that filter replacement costs can be reduced and production time is not interrupted.

Abstract

Dye-sensitized solar cells (DSSCs) offer advantages such as low production costs, simple fabrication methods, and reduced toxicity compared to silicon-based solar cells, although their efficiency remains a major limitation. The aim of this review is to discuss the fundamental principles of DSSCs and evaluate the electrochemical techniques used to optimize their performance. The method employed is a narrative literature review, allowing the author to synthesize relevant literature from various sources. Current-voltage (I-V) measurements and electrochemical impedance spectroscopy (EIS) are identified as the primary tools for assessing DSSC efficiency and quality. The findings indicate that I-V measurements provide critical metrics such as efficiency and fill factor, while EIS helps identify charge transfer resistance and improves cell stability. Techniques such as voltammetry and Tafel polarization plots offer additional insights into catalytic activity and diffusivity. This review underscores the importance of electrochemical characterization in supporting efficiency improvements and the development of new materials, with EIS playing a key role in modelling cell morphology through equivalent circuit analysis.

Abstract

Ketepatan posisi titik potong merupakan aspek krusial dalam proses pemotongan menggunakan mesin laser cutting CO₂. Namun, operator sering mengalami kesulitan dalam menentukan titik awal pemotongan karena tidak adanya panduan visual yang presisi, terutama saat ruang material sangat terbatas. Untuk menjawab permasalahan tersebut, penelitian ini bertujuan untuk merancang dan membangun bracket pointer sebagai dudukan bagi modul laser pointer yang berfungsi memberikan panduan visual sebelum proses pemotongan dimulai. Proses rancang bangun dilakukan melalui tahapan identifikasi kebutuhan, desain menggunakan perangkat lunak CAD, pembuatan prototipe dengan metode pencetakan 3D berbahan ABS, serta pengujian langsung pada mesin laser cutting CO₂. Parameter pencetakan yang digunakan dalam proses ini antara lain layer height 0,2 mm, infill density 4 mm, suhu nozzle 250°C, suhu heated bed 100°C, dan kecepatan cetak 60 mm/s. Hasil pengujian menunjukkan bahwa penggunaan laser pointer secara signifikan membantu meningkatkan akurasi penempatan awal titik potong. . Selain itu, penggunaan alat bantu ini mampu menghemat waktu pengaturan awal hingga 3 menit atau setara dengan peningkatan efisiensi waktu sebesar 14,3%. Bracket berfungsi dengan baik dalam kondisi normal, namun dapat mengalami sedikit pergeseran jika terjadi getaran berat pada mesin. Secara umum, prototipe ini dinilai efektif sebagai perangkat bantu dalam meningkatkan efisiensi proses setup dan kualitas produksi pada mesin laser cutting CO₂.

Abstract

Penelitian ini mengkaji strategi penyediaan air bersih berkelanjutan di Kota Magelang dengan memanfaatkan energi surya sebagai sumber energi terbarukan hingga tahun 2033. Melalui pendekatan analitis berbasis data sekunder, dilakukan proyeksi pertumbuhan jumlah penduduk dan kebutuhan air bersih menggunakan metode regresi linear yang paling representatif. Hasil proyeksi menunjukkan peningkatan kebutuhan air bersih dari 240,06 liter/detik pada tahun 2025 menjadi 252,30 liter/detik pada 2033. Konsumsi energi penyediaan air dihitung dengan dua skenario efisiensi, yakni kondisi eksisting (SEC 0,888 kWh/m³) dan sistem efisien (SEC 0,35 kWh/m³), dimana penggunaan energi dapat ditekan hingga 59% pada skenario efisien. Potensi energi surya di Kota Magelang dengan radiasi tahunan sekitar 1.817,1 kWh/m² memungkinkan penerapan sistem photovoltaic (PV) untuk mendukung penyediaan energi tersebut. Kapasitas PLTS terinstal yang dibutuhkan berkisar dari 18,5 kWp hingga 381 kWp untuk memenuhi 1% hingga 20% kebutuhan energi tahunan. Implementasi sistem PV ini berpotensi mengurangi ketergantungan pada energi fosil dan mendukung target transisi energi bersih daerah. Studi ini memberikan rekomendasi strategis untuk integrasi energi terbarukan dalam sistem penyediaan air bersih, mendukung pembangunanberkelanjutan, dan mitigasi risiko krisis air di masa depan.
