Path planning is a sequence of states to move objects from the initial state to the final state and avoid impassable areas. Objects here can be robots, autonomous cars, and others. The A* algorithm is a path search algorithm that uses distance estimation by using the closest path search to reach the destination. Weighted A* is an algorithm used to solve the pathfinding problem by changing the weight value in the heuristic function. The purpose of this study is to analyze the comparison of the Weighted A* algorithm with the A* algorithm and analyze the effect of the heuristic weight value on the Weighted A* algorithm. The tests carried out are using maze, narrow, trap, clutter environments. The results obtained in the comparison of the Weighted A* and A* algorithms, from the test results, the Weighted A* algorithm produces a better search time of 0.33 seconds, while the A* algorithm produces a time of 1.40 seconds. But the A* algorithm can produce a more optimal path of 163.69 than the Weighted A* algorithm which produces a path of 164.52. With a strategy that emphasizes choosing nodes that are closer to the goal node, Weighted A* can produce a path with a faster computation time. While the A* algorithm because it chooses the node with the smallest heuristic value, it can produce a more optimal path. Weighted A* is suitable to be implemented on systems that require shorter path-finding times but do not have to be optimal. The A* algorithm is suitable to be implemented in systems that require optimal paths even though the search time is not too fast

Regular watering and with the right portion are very important in melon cultivation. The current melon fruit watering system is still done by turning the water tap on the watering pipe block to flow the water. Therefore, there needs to be an application of technology that can help melon farmers in the watering process. Although many researchers have developed automatic watering models, some have even used IoT technology. However, this study has not considered the need for watering based on the age of the melon plant itself. In fact, this automatic watering system based on the age of the melon plant is what melon farmers need, so that the melon plants grow well and produce quality fruit. This study aims to develop a distributed automatic watering system based on the age of the plant and nutritional needs. The methods used include the integration of electronic instrumentation technology and distributed automatic control to provide the right watering process. The results of the study showed that this system is effective in optimizing the watering process so that nutrients can be absorbed properly. With this system, the level of fruit sweetness at harvest can reach 17 brix, and the size of the honey melon produced can reach 1.2 kg. In conclusion, this distributed automatic watering system is a smart solution to optimize the growth and yield of melon plants.

The honeydew melon cultivation model using the hydroponic greenhouse method has been widely applied due to its ease in controlling nutrients and the environment. However, complaints from farmers regarding the inaccuracy of nutrient levels and the dynamic environmental changes, that hinder plant growth and fruit quality, have surfaced. The development of autonomous control technology is crucial as a strategic solution to this issue since the quality of honeydew melon management lies in achieving precise and accurate nutrient levels. On the other hand, managing standardized nutrient composition often becomes a challenge for farmers as the needs constantly change over time. Conventional systems are not yet capable of accurately measuring nutrient levels in line with the plant’s growth stages. According to the objectives of this study, which is to improve the productivity and quality of honeydew melons based on the increase in the sweetness index, the development of an autonomous nutrient control system is proposed. This system integrates artificial intelligence algorithms, namely CNN and Fuzzy Logic, to process plant height image data and multisensor data for system control processes. The research findings that applying this integrated technique has resulted in a sweetness increase of 11.7%, or from the previous value of 15 brix to 17 brix. Even a one-point increase in the brix value leads to a sugar increase of 1 gram per 100 gram of liquid content in the fruit, contributing significantly to the market value. These results indicate that AI-supported agricultural management can be realized in future modern farming practices.

Multi-substrate antenna material is a combination of more than one primary antenna base material where this substrate material can determine the quality of antenna performance. A quantitative empirical approach is carried out to achieve maximum performance by processing the dielectric constant of the substrate to obtain other antenna parameters. This aims to increase the stability of the antenna gain and produce a large bandwidth. The results show that diamond has a bandwidth of 75 MHz with a maximum gain of 4.228 dBi and a VSWR of 18.017. While epoxy FR-4 produces a bandwidth of 57 MHz with a maximum gain of 3.444 dBi and a VSWR of 2.011, the quartz material produces a bandwidth of 80 MHz with a maximum gain of 4.426 dBi and a VSWR of 10.884. The conclusion is that FR-4 epoxy substrate performs better than diamond and quartz. It is hoped that the results of this research will impact the development of a smart antenna system.

Berkembangnya jaringan gardu induk guna memenuhi kebutuhan masyarakat sebagai konsumen diperlukan fasilitas sistem komunikasi via jala-jala listrik yang disebut power line carrier (PLC) sebagai penunjang pelaksanan operasion-al sistem tenaga listrik terutama dalam proses pengiriman data informasi disamping untuk keperluan utama yaitu distribusi tenaga listrik. Alokasi frekuen-si sistem komunikasi ini diantara frekuensi 50 Hz - 500 kHz. Alasan utama alo-kasi frekuensi ini digunakan karena tidak banyak digunakan sehingga diharap-kan tidak akan mengganggu dan terganggu oleh sistem komunikasi lainnya sebab media transmisinya khusus memanfaatkan saluran tegangan tinggi.Salah satu peralatan utama pada sistem komunikasi PLC ini adalah wave trap dan coupling capasitor dengan beberapa fungsi dan sifat kerja yaitu wave trap memiliki harga impedansi rendah terhadap frekuensi jala-jala serta memiliki impedansi besar untuk frekuensi pembawa informasi. Sedangkan coupling ca-pasitor memiliki harga impedansi besar terhadap frekuensi jala-jala serta mem-iliki impedansi kecil ketika berada pada alokasi frekuensi pembawa informasi. Karena itu perhitungan-perhitungan nilai reaktansi induktf dan kapasitif ter-hadap frekuensi kerja pada peralatan wave trap dan coupling capasitor memba-wa pengaruh besar terhadap nilai impedansi dan kinerja system komunikasi PLC ini. Kemudian pengaruh peralatan ini dapat menghasilkan koordinasi yang optimal dalam pengamatan pusat-pusat beban (GI) dan pusat-pusat pembang-kit.
