Abstract

The rainy season is an obstacle for everyone, especially drying shoes, because rain can hinder the process of drying shoes. Currently, shoes are still dried using the conventional method, namely by utilizing the sun's heat. The next development is a system for drying shoes using gas fuel, but it has the potential for fire. In this final project, a shoe drying system is designed which is controlled using PI control according to a specified setpoint to dry shoes when exposed to rain or at night. To get the appropriate room temperature, the output voltage from the heater needs to be controlled using the Digital Firing Angle. The ignition angle is regulated by the Digital Firing Angle circuit. To maintain the temperature conditions in a stable condition, namely 65°C, this tool is controlled using PI (Proportional Integral) control. This dryer is designed for a maximum of 1 pair of wet shoes. With final humidity results in the drying room ≤ 20%RH. With this final project, it can dry shoes in rainy conditions in 94 minutes for synthetic leather shoes and 104 minutes for leather shoes.

Abstract

One potential approach to addressing the challenges posed by the advent of Industry 4.0 and Society 5.0 is to offer robotics training. This endeavor aims to enhance students' foundational understanding of STEM (Science, Technology, Engineering, and Mathematics) disciplines. The study involved collaborating with the Pondok Pesantren Granada, an Islamic Boarding School located in Batam, to provide robotics training as community service activities. The study included 29 trainees: 15 from class XI and 7 from classes X and XII. The teaching was conducted using a combination of didactic instruction, interactive discourse, and hands-on exercises. Trainees are administered a written examination to assess their proficiency level before and after the training program. The training outcomes exhibited a significant improvement in the mean STEM proficiency of trainees, with an increase of 38.15%. Furthermore, a series of activities have been effectively implemented, resulting in trainee satisfaction ratings exceeding 50% concerning course materials, trainer, and teaching equipment. A mere 17% of the individuals undergoing training expressed dissatisfaction with the allocated time, particularly the hands-on component's duration.

Abstract

Photovoltaic system efficiency drops significantly under Partial Shading Conditions (PSC) due to multi-modal power characteristics. Conventional algorithms and standard metaheuristics like Harris Hawks Optimization (HHO) frequently suffer from premature convergence and local peak entrapment. To resolve this, an Enhanced Harris Hawks Optimization (EHHO) strategy integrated with a continuous-current CUK converter is proposed for Maximum Power Point Tracking (MPPT). EHHO revitalizes the search mechanism using logarithmic, exponential functions, and a traveling distance rate to definitively prevent local optima entrapment. Simulations verify that EHHO delivers a superior average tracking accuracy of 99.43% within 0.260 s. In direct contrast, benchmark algorithms (PSO and HHO) exhibit severe performance degradation due to deceptive local peaks. Furthermore, EHHO yields the highest cumulative energy harvest of 27.44 Ws, confirming its absolute robustness in maximizing energy extraction within dynamic environments.

Abstract

Electrical control capacity or quality control capacity in electrical systems has always been very vital. However, the main attention should be focused on the characteristics of the supply voltage, especially in the modern era. A major constraint in the electrical structure is low voltage. Low voltage is a source of disturbance in the electrical system that affects the agility of related electrical equipment and can shorten the life of equipment, including battery components in DC energy systems such as solar panels. To anticipate the situation, low voltage circuit breaker hardware is used to protect batteries and DC devices from low voltage conditions, using a potentiometer as a voltage regulator, IC 7809 as a battery input voltage reducer, a switch to disconnect the battery, a power source, and a voltage display on the LCD screen and microcontroller control using Arduino Nano. The strategy applied can be a growth strategy or a research and development strategy. This approach is the foundation for planning and building the Moo voltage circuit breaker to protect batteries and DC devices. In the voltage test, Moo was able to disconnect the DC battery with ±99.795% accuracy. Standard tests for low voltage circuit breakers at 12 V and 24 V showed a difference of ±0.096 V and an error of ±0.554%.

Abstract

Indonesia secara geografis terletak di daerah khatulistiwa dengan iklim tropis dan dikelilingi oleh lautan, menyebabkan tingginya tingkat hari guruh yang terjadi diwilayah ini. Begitu pula dengan pulau Batam yang terletak di Provinsi Kepulauan Riau memiliki karakteristik hari guruh yang tinggi, dimana hal ini dapat dilihat dari tingkat isokraunic level sambaran yang terjadi di area ini yang dapat mencapai lebih dari 215 sambaran per tahun. Kondisi ini menyebabkan perlunya perencanaan dan instalasi sistem penyalur petir eksternal yang dilakukan di area Power House Batamindo Industrial Park, agar kehandalan suplai energi listrik untuk pelanggan diwilayah industri tetap handal dan aman, walaupun tingkat sambaran petir diwilayah ini tinggi. Perencanaan dan instalasi sistem penyalur petir dilakukan dengan mengacu standar Peraturan Umum Instalasi Listrik (PUIL) dan standar nasional melalui Persyaratan Umum Instalasi Penangkal Petir. Dari hasil perencanaan dan instalasi sistem penyalur petir yang dilakukan oleh PT Lancang Kuning Sukses (PT LKS) selaku kontraktor pelaksana project ini, dilakukan pengumpulan data berupa data sheet head unit penyalur petir dimensi ketinggian dan luasan area proteksi serta melakukan pengukuran tahanan pentanahan. Dari pengukuran yang dilakukan terhadap pentanahan sistem penyalur petir diperoleh nilai sebesar 0,56 Ohm, dimana besar nilai pentanahan ini telah sesuai dengan standar PUIL sebesar < 5 Ohm.
