Abstract

Robotics has seen an explosive increase in usage in the past few decades owing to its abundance of benefits and automation capabilities. The use of robotics is especially prominent in industries where the demand for precise and automatic robots in order to increase production efficiency is high. One of the robots commonly used in these industries is the arm robot model, which is a machine designed specifically to mimic some of the human arm’s capabilities in order to execute certain tasks over and over again, either autonomously or not. This paper will discuss the design of a robotic arm with five degrees of freedom capable of picking up and placing objects with three different colors and sorting the objects based on their size, starting from the largest to the smallest. The inclusion of an additional degree of freedom allows the robot to adjust the rotation of its grip to properly grab rotated objects. With an ESP32-CAM acting as its eyes, the robot is aided by a Python program run remotely on a separate Laptop in order to analyze video stream uploaded by the camera to determine the coordinates, color, size, and rotation of objects placed within the Detection Zone. The implementation of inverse kinematics equations run on an ESP32 microcontroller allows the robot to reach arbitrary coordinates specified by the Python program. Testing revealed that the resulting robot is able to perform the tasks it was designed to, namely recognizing and sorting colored boxes of different colors and sizes, with an accuracy 100% in recognition tasks and an accuracy of 91.5% in sorting tasks.

Abstract

Lemukutan Island is an island administratively located in Bengkayang Regency, West Kalimantan province. Currently, electrical energy on Lemukutan Island is supplied by 1 unit of Diesel Power Plant (PLTD) which has an installed capacity of 140 kW, but PLTD only operates 14 hours/day, from 16.00 to 06.00 WIB. One of the efforts to be able to provide 24-hour electricity services on Lemukutan Island can be done by operating PLTD for 24 hours and alternative efforts by utilizing hybrid Solar Power Plants (PLTS). In a hybrid system between PLTD and PLTS, researchers calculate the capacity of solar panels, calculate the number of batteries, calculate the number of solar charge contoller, and calculate the capacity of the inverter to be used. The economic analysis used only calculates the initial investment cost and OM costs. Based on the calculation of solar panels used as many as 1473 units with a capacity of 550 Wp, the total watt-peak power is 810 kWp, batteries with a total energy of 2418.9 kWh, Solar Charge Controller using 207 units and 7 inverter units. In the calculation of the total initial investment costs incurred amounted to Rp.10,122,917,594 and investment cost of Rp. 12,497,429/kWp if the installation cost is 0.6%. OM costs amounted to Rp.101,229,175 while the operational and maintenance costs that must be incurred in accordance with the age of the PLTS project that is run following the life of solar panels for 25 years amounted to Rp. 1,760,485,107.

Abstract

This research employs Optisystem for evaluating network quality through calculation and simulation. It includes direct observation of installed devices at Perum 4 East Pontianak and network simulations using parameters like Power Link Budget, Rise Time Budget, BER, and Q factor. Calculations indicate that power levels on the downstream and upstream sides meet the standard. RTB analysis and BER and Q factor simulations confirm compliance with PT Panglima Kamayo Media and ITU-T G.984 standards. However, a design-implementation mismatch affects two consumers with significant power deviations, necessitating network improvements. PLB and RTB calculations on both sides confirm compliance with standards, and simulations validate the furthest network's feasibility. Yet, two specific consumers, 24 and 27, require improvements due to Prx power exceeding limits. These enhancements should consider internal and external factors, such as anthill interference. Overall, Perum 4 East Pontianak's FTTH network meets standards with potential improvements for uniformity, offering valuable guidance for PT Panglima Kamayo Media in enhancing consumer services.

Abstract

This study aims to evaluate the performance and capacity of the Solar Power Plant (PLTS) system that has been installed on charging batteries for street lighting. Before cleaning the surface of the solar panel, the energy produced only reached 707.46Wh, and after cleaning, the energy produced increased to 859.77Wh. However, these results still do not meet the daily energy requirements for a 12-hour battery charge. The research methodology includes analyzing the impact of dust on solar panels, evaluating the performance of PLTS, and calculating daily energy requirements. Based on the PLTS battery capacity of 9600Wh, the maximum energy obtained from charging the battery is still insufficient to power two street lighting lamps for 12 hours. Therefore, an evaluation of the installed PLTS was conducted, resulting in several findings. First, it is necessary to add 11 units of solar panels with a capacity of 455Wp so that the required energy can be met. Second, the capacity of the installed battery is sufficient to meet the energy needs of the lighting. Third, the capacity of the Solar Charge Controller (SCC) needs to be increased to 150Ampere due to the addition of solar panels. Finally, the inverter that has been installed with an output of 1000Watt is adequate for the needs of the system. The results of this evaluation can serve as a basis for improving the performance of the PLTS in order to meet the desired energy needs.
