Abstract

Wireless distribution system (WDS) is a system to expand the wireless network and MAC address as destination addressess. Some documents have discussed WDS technology which one of it says that there is decline in throughput almost half a percent.In this paper, we examine how far the WDS impacts on packet loss and delay that occur when using different topologies in the network based Mikrotik. In the test, we first determined the topology and the location of the router and then we configured WDS route with registering the path between the router's MAC address. Secondly, we delivered streaming videos from server to the client and run the network monitoring software to record the network activity. Thirdly, we analyzed the delay, throughput, and packet loss as a result of the monitoring network.Based on the research examination, it is shown that there is no significant difference between the topology scheme 1 and the topology scheme 2. The performance of the router Master, router 1 and router 2 between topology 1 and topology 2, using the testing parameters: delay, throughput, and packet loss are the same. This is mainly because both of topologies have the same number of hops. On the other hand, there are significant difference in term of delay, throughput and packet loss for router 3 and router 4 both topologies. This is due to that the Master router to router 3 and the router 4 in the topology 2 has more hops than topology 1.

Abstract

Saat ini kebutuhan akan energi listrik semakin meningkat. Peningkatan akan kebutuhan energi listrik beriringan dengan banyaknya orang yang mulai peduli dengan masalah lingkungan yang disebabkan oleh polusi serta terkait dengan ketersediaan bahan bakar fosil yang makin menipis. Sinar matahari menjadi salah satu sumber energi yang dilirik oleh banyak orang karena ketersediaannya yang melimpah. Salah satu alat untuk memanfaatkan sinar matahari agar berfungsi sebagai sumber energi listrik adalah panel surya. Panel surya saat ini masih bayak dipakai sebagai sumber energi listrik alternatif seperti pengairan kolam, stasiun pemancar radiu di dataran tinggi , penerangan jalan umum dan sebagian untuk rumah tangga. Agar penyerapan cahaya matahari menjadi optimal diperlukan solar tracking system untuk melakukan tracking terhadap sinar matahari. Solar tracking system pada umumnya hanya 1 axis, sehingga penyerapan energi kurang optimal oleh gerak semu matahari tahunan.  Maka dari itu penulis merancang solar tracking system dual axis agar penyerapan cahaya matahari menjadi optimal. Panel surya yang dipakai 50 WP mampu menghasilkan tegangan 17,4 Volt dan arus maksimal 3,14 Ampere sehingga daya puncak yang dihasilkan sebesar 50 Watt. Dengan mengikuti arah datangnya sinar matahari solar tracking system dual axis mampu menghasilkan daya rata-rata harian sebesar 62 % dari daya puncak yakni sebesar 31 Watt. Pringkuku yang terletak di Kabupaten Pacitan adalah salahsatu desa yang masih minim yang dapat dilayani sambungan listrik karena letak topologoginya yang berbukit sedangkan memiliki potensi pembangkit tenga sel surya.

Abstract

Geological layout contributes Indonesia in becoming one of the most dangerous countries with natural disasters. The eruption of volcano is one of the most dangerous natural disasters in the world. However, our efforts in disaster mitigation is not enough, especially in developing new mitigation technology. We already know that the Wireless Sensor Network (WSN) technology can be an alternative electronic communications technology that can be used in disaster mitigation because the WSN has the ability to communicate using Radio Frequency (RF) and can be connected to a digital or analog sensor. Then, the Computer Personal Unit (CPU) in WSN is used to run the protocols, such as hop-to-hop protocols. Later, we can build a monitoring system that have small size, energy saving, low cost, and capable to show real-time monitoring. The problem that must be solved in this research is how to make a design communication based on WSN that have accordance with the extreme conditions like at Kelud Volcano. Currently, with utilization of temperature sensor and gas sensor and delivery schedule of data packets as parameters, we want to find how to test the design with minimal electricity supply.

Meskipun dapat menggunakan inspeksi manual terhadap kecacatan pada PCB, namun metode tersebut memiliki keterbatasan terhadap ketelitian dan waktu. Oleh karena itu, penelitian ini dilakukan untuk mengimplementasikan Machine Learning dalam deteksi kecacatan pada PCB. Dalam pengaplikasiannya, penelitian ini menggunakan algoritma deteksi objek YOLOv5 (You Look Only Once versi 5), yang merupakan pengembangan dari convolutional neural network. Fokus penelitian ini adalah membangun sistem yang dapat mengidentifikasi kecacatan pada PCB menggunakan algoritma YOLOv5. Dataset yang digunakan terdiri dari 600 gambar, dengan 480 data latih dan 120 data uji. Jenis kecacatan PCB yang diidentifikasi meliputi open circuit, missing hole, mouse bite, short, spur, dan spurious copper. Hasil penelitian menunjukkan bahwa penggunaan YOLOv5m menghasilkan nilai mean Average Precision (mAP) sebesar 95,3%. Selain itu, dalam pengujian dengan 120 data uji, model berhasil mencapai akurasi sebesar 93,83%, presisi 98,13%, recall 95,43%, dan  error 6,17%.  Selain itu peningkatan spesifikasi hardware juga berpengaruh dalam kecepatan deteksi objek kecacatan pada PCB.Kata kunci : PCB, kecacatan, Machine Learning, convolutional neural network, YOLOv5 The quality of an electronic circuit depends significantly on the quality of the Printed Circuit Board (PCB) supporting its operation.

Abstract

Limitations in traffic management features on ISP-provided routers are a common issue in industrial Wi-Fi networks, particularly in maintaining the stability of production network connections. The absence of bandwidth control mechanisms allows non-priority devices to consume excessive bandwidth, thereby degrading the quality of operational network services. This study aims to analyze the effectiveness of Evil Limiter as a software-based bandwidth management solution by utilizing the ARP redirection mechanism without requiring administrative access to the router or modifications to the network infrastructure. The research employs an experimental approach conducted on a production Wi-Fi network at PT Bimuda Karya Teknik using three testing scenarios: baseline, limiting, and blocking. Network performance is evaluated based on Quality of Service (QoS) parameters referring to the TIPHON standard, including throughput, delay, jitter, and packet loss. The results indicate that Evil Limiter is effective in controlling traffic from non-priority devices, where in the blocking scenario, target devices are completely isolated with a throughput of 0 Mbps and a packet loss of 100%, while the limiting scenario significantly reduces internet access for non-priority devices. Overall, the proposed method is proven to improve network stability for priority devices, particularly under high network load conditions.

Abstract

Sidosari Village in Salaman District, Magelang Regency, has strong agricultural potential, mainly from rice farming as the main source of income. However, heavy use of chemical fertilizers and pesticides has caused soil degradation, ecological imbalance, and health problems for farmers. This community service program introduced Biosaka, a natural elicitor made from local weeds, as an environmentally friendly alternative. Biosaka strengthens plant resistance to pests and diseases and can reduce chemical fertilizer use by 50 to 90 percent. The program used Participatory Action Research (PAR) with stages of problem identification, socialization, hands-on training, observation, and reflection. It was held from July 15 to August 2, 2024, at Sidosari Village Hall and involved representatives from 30 farmer groups. Participants successfully produced Biosaka solutions that met quality criteria, including homogeneity, absence of sediment, and appropriate pH and TDS levels. They also demonstrated high enthusiasm and provided positive feedback on the accessibility and benefits of Biosaka. The activity fostered collaboration among students, farmers, and the community, thereby increasing awareness and skills in sustainable agricultural practices. Results indicate potential improvements in soil health, reduced production costs, and long-term environmental sustainability in local agriculture.
