Abstract

The Indonesian wood industry is diverse, with wood carving being one of its most popular products. However, the manual wood carving process is not suitable for large-scale production. To address this challenge, a new tool has been developed to increase the production of wood crafts, especially calligraphy carving. This tool is a 3-axis wood carving CNC router machine controlled by a computer and smartphone. The CNC router machine was designed using the CNC Shield V3 and the Arduino Uno R3 motor driver, A4988 as a stepper motor controller. The mechanism applied includes creating vector images programmed with gcode, controlling and engraving calligraphy through software on computers and applications on smartphones with Bluetooth HC – 05 communication with a maximum distance of smaller than 10 meters. Based on control data by computer testing geometry testing circle dimensions of 58 mm x 56 mm and feed rates of 5 mm/sec, 8 mm/sec and 10 mm/sec with engraving times of 01:12, 00:48 and 00:42. Testing Muhammad's carving with dimensions of 100 mm x 100 mm and feed rates of 5 mm/sec, 8 mm/sec and 10 mm/sec with engraving times of 05:22, 03:45 and 03:24. Tests for cutting 12 mm thick MDF wood with a depth 1.5 mm and a feed rate of 5 mm/sec cuts 8 rounds for 13:12 min/sec. The control data by smartphone testing the geometry of the circle with dimensions of 50 mm x 50 mm and a feed rate of 500mm/min with a carving time of 58:43 minutes. Testing Muhammad's engraving dimensions of 70mm x 60mm and feed rates of 500 mm/min, 800 mm/min, and 1000 mm/min with engraving times of 54:34, 39:25, and 35:28. The test for cutting 12 mm thick MDF wood with a depth of 1.5 mm and a feed rate of 500 mm/min-cut 8x rounds for 10:21 minutes/second.

Abstract

Widarapayung Wetan Village was designated as an innovation village by the Cilacap Regency Innovation Village Determination which is located in Binangun District, Cilacap Regency. The main potential of Widarapayung Wetan Village is in the tourism sector, such as Widarapayung Beach and the pioneering tourist village. The facilities that have been built and already exist in this pilot tourism village are an art performance stage, pavilion, gazebo, gamelan instruments, plantation land, and rice fields. One of the pioneering developments of tourist villages is the development of educational tourism. This community service activity applies appropriate technology by developing water pump technology for irrigating rice fields using solar energy. Apart from irrigating rice fields, this solar-powered water pump technology is also used for educational tourism at the Widarapayung Wetan tourism village pilot, especially in the field of utilizing new and renewable energy. The stages of work carried out included surveying the installation site, designing and manufacturing a solar water pump system, system installation at the installation site, operational trials of pumps, and operational training and pump maintenance. The result of this activity is a solar water pump system for irrigating rice fields with a capacity of 30 liters/minute.

Abstract

Education is progressing faster than at any other time in history. Educators are becoming increasingly conscious that today's learning media are developing to match future realities. Education must establish new approaches in the learning process by employing virtual classrooms and tools and technology. The virtual classroom concept offers a solution for today's and tomorrow's educational needs. To prepare for future employment, students require a holistic education that combines practical occupational skills, communication methods, and leadership development. This paper will give a bibliometric analysis of the term virtual classroom as a learning media, focusing on future research trends in vocational education. The articles were obtained with the help of the Publish or Perish software and the Scopus database. With a search period spanning 2013 to 2022, 405 articles were evaluated (9 years period). The desktop version of the Mendeley program is used to handle the references. VOS Viewer software was used to classify the articles by generating six clusters. The main keywords from the six groupings are virtual reality, e-learning, teaching, education, augmented reality, and improved classroom instruction.

Abstract

Industri pada umumnya adalah aktivitas untuk menghasilkan produk. Dalam kegiatan industri terdapat beberapa proses seperti pengumpulan bahan baku, produksi, quality control, pengemasan, dan pemasaran. Salah satu masalah yang sering terjadi adalah pada tahap pengemasan. Jika proses pengemasan tidak efisien, hal ini akan menghambat hasil produksi karena membutuhkan banyak waktu dan tenaga. Oleh karena itu, tugas akhir ini bertujuan untuk merancang dan membuat alat pengemas plastik yang dapat mengubah plastik lembaran menjadi kemasan. Alat ini dilengkapi dengan fitur pemantauan suhu pada pemanas dan pemantauan berat kemasan untuk meningkatkan kualitas hasil kemasan. Sistem ini menggunakan mikrokontroler Arduino Mega2560 sebagai pusat kendali, motor servo untuk katup bak penampungan, sensor load cell untuk penimbangan, motor DC sebagai penggerak sealer, dan LCD untuk menampilkan data. Alat ini mengubah plastik lembaran menjadi kemasan yang direkatkan menggunakan pemanas. Komponen pendukung lainnya meliputi relay dan sensor suhu DS18B20. Hasil pengujian menunjukkan alat ini dapat bekerja optimal pada suhu 60-65°C dengan delay pengepresan 2500 ms. Pengemasan menunjukkan akurasi berat yang baik dengan persentase error rata-rata 8,75% untuk 100gram dan 5,05% untuk 200gram. Selisih berat rata-rata antara load cell dan timbangan konvensional adalah 1,29 gram, dan sensor suhu menunjukkan selisih rata-rata 0,878°C dengan error 1,818%.

Abstract

Before coffee products are marketed, packaging is generally carried out first. Apart from protecting against damage, the packaging also aims to make it easier to carry while traveling. The conventional packaging process is quite time and energy consuming. This results in the packaging process being less efficient. With an automatic packaging system, it is hoped that it will make things easier and save time and energy. Automatic coffee bean packaging tools are built using several electronic devices. Arduino Uno is used as a controller, a load cell sensor to weigh the coffee packaging, a DS18B20 temperature sensor to measure the temperature of the packaging sealer and a proximity sensor to detect plastic packaging. In the actuator section, a servo motor is used to open the coffee bean reservoir valve (hopper tank), a DC motor is used to pull the packaging plastic and a stepper motor is used to press the packaging plastic. The plastic press is equipped with a heating mechanism using nickel wire so that the two layers of plastic can stick together. An LCD module is used to display information on the weight value of the coffee packaging, the temperature value of the sealer and the status of the packaging process. From the test results, it is known that the coffee bean packaging tool is capable of packaging coffee beans automatically. Coffee beans can be packaged in plastic with the weight and length of the packaging according to the design with a success rate of up to 87.5%

Abstract

Indonesia has a large solar energy potential, with an average radiation of 4.5-4.8 kWh/m² every day. Politeknik Negeri Cilacap (PNC) can take advantage of this opportunity to develop a Solar Power Plant. This study examines the possibility of building an on-grid rooftop solar power plant in the Department of Electrical and Mechatronics Engineering. This study uses Homer to simulate the solar power plant design. The parameters discussed are total energy production (kWh/year), renewable fraction, net present cost/NPC (Rp) which is all costs used in construction, both in installation and operation of the solar power plant and Cost of energy/COE (Rp/kWh) which is the cost incurred to produce electrical energy per 1 kWh. The results of the study include an average solar energy at PNC of 4.66 kWh/m²/day. Based on Homer's simulation results, the total energy generated by the solar power plant is 149,056 kWh/year, with 68,599 kWh/year from photovoltaic and 80,457 kWh/year from the PLN grid. The renewable fraction is 44.8%. The NPC is Rp 1,880,000,000, and the CoE is Rp 1,000/kWh.
