Abstract

Jalan Surodinawan terdapat berbagai aktifitas dari fasilitas-fasilitas yang dibutuhkan masyarakat. Dampak yang ditimbulkan adalah bertambahnya volume kendaraan pada hari dan jam tertentu terutama pada jam-jam sibuk. Tujuan kajian ini adalah untuk mengetahui kinerja ruas jalan serta pengaruh hambatan samping terhadap ruas jalan Surodinawan Kota Mojokerto. Penelitian ini dilakukan dengan membagi Jalan Surodinawan menjadi 3 segmen, metode yang digunakan yaitu PKJI 2014. Hasil analisa dari penelitian ini yaitu volume lalu lintas pada segmen 1 sebesar 1396,53 skr/jam, segmen 2 sebesar 1135,44 skr/jam, dan segmen 3 sebesar 1199,07 skr/jam. Hambatan samping yang terjadi pada segmen 1 sebesar 561,36 kejadian dengan kelas hambatan samping Tinggi, segmen 2 sebesar 187,14 kejadian dengan kelas hambatan samping Rendah, segmen 3 sebesar 169,87 kejadian dengan kelas hambatan samping Rendah. Kinerja ruas jalan Surodinawan Kota Mojokerto masih layak dengan nilai derajat kejenuhan pada segmen 1 sebesar 0,58, segmen 2 sebesar 0,49, segmen 3 sebesar 0,50. Dari analisa kinerja pada ruas jalan Surodinawan Kota Mojokerto dengan tanpa memperhitungkan hambatan samping, didapatkan nilai kapasitas maupun kinerja ruas jalan mengalami peningkatan. Fenomena ini menyatakan bahwa adanya aktifitas samping jalan berdampak signifikan terhadap penurunan kinerja segmen jalan di sepanjang ruas Jl. Surodinawan Kota Mojokerto. Besarnya penurunan kinerja pada segmen 1 sebesar 12%, sedangkan pada segmen 2 dan 3 penurunan kinerja sebesar 4%.

Abstract

Drought trends are occurring throughout Indonesia, including in Lamongan Regency. The problems caused by drought significantly affect the agricultural sector in Lamongan, with varying impacts each year. This study uses the Normalized Difference Vegetation Index (NDVI) method integrated with Geographic Information Systems (GIS) to monitor and analyze vegetation conditions as an indicator of drought. Based on the Landsat 8 imagery analysis from August to October 2019-2021, the results show significant changes in vegetation conditions related to drought. The year 2020 showed a decrease in areas with high greenness, while 2021 showed a significant recovery. This vegetation monitoring is expected to serve as a basis for more effective drought mitigation policies for the agricultural sector in Lamongan Regency.

Abstract

The power breaker (PMT) in the transmission system functions as a load breaker both under normal circumstances and when a disturbance occurs. In July 2021 it was discovered that there was an SF6 gas leak at (PMT) bay Arjawinangun 2 at Gi Sunyaragi. Under these conditions an overhaul was carried out which in the implementation found several sources of causes of leaks such as scale and corrosion at the joints and packing conditions that were no longer flexible. Before the implementation and after the implementation of the overhoul, tests were carried out including: contact resistance testing, insulation resistance testing and after a series of tests were carried out, then an analysis of the test results was carried out and a voltage drop simulation was carried out using the Etap 12.6 software from a series of activities, 5 simulation results were obtained and concluded that the system is still within safe limits (up 5%, down 10% from the nominal voltage). As well as other tests such as isolation resistance and contact resistance are still included in the specified standard category, so it is concluded that the PMT bay Arjawinangun 2 is in good condition and safe to operate.

Abstract

Asset monitoring at the Surakarta City Department of Education is still carried out manually by visiting all related institutions that receive financial aid. This activity is conducted daily every year and consumes a significant amount of labor, time, and costs, potentially leading to inefficiencies, data recording errors, and a lack of transparency in the asset reporting and monitoring processes. These issues can hinder decision-making processes related to asset management and reduce the accountability of relevant parties. This research aims to develop a web-based Asset Monitoring Information System using PHP and MySQL to enhance efficiency and transparency in asset management. The system development method used is the System Development Life Cycle (SDLC), which includes the stages of planning, needs analysis, design, implementation, and system testing. The results of this research show that the developed system can accelerate the asset management process, minimize data errors, and improve the accessibility and transparency of asset reporting. The system also facilitates real-time asset monitoring and simplifies the validation process by authorized personnel. The designed system is expected to improve operational efficiency and accountability in asset monitoring at the Surakarta City Department of Education.

Abstract

The cleanliness of chick coops is crucial, especially in large-scale poultry farms, as it directly affects the health and well-being of the chicks. Manual cleaning of coops can be very tiring and inefficient. This study aims to design and implement an automatic chick coop cleaning system based on a conveyor belt equipped with a DHT22 temperature sensor and an MQ-135 ammonia sensor, using an ESP32 module for automatic control and Internet of Things (IoT) integration. The results show that the system operates well, with temperature measurement errors ranging from 0% to 3,10% and ammonia measurements ranging from 7 to 40,00 ppm. To improve reliability, it is recommended to use sensors with higher accuracy and add an offline mode so the system can still function without an internet connectio

Abstract

Penelitian ini bertujuan untuk mengevaluasi performa Optical Character Recognition (OCR) dalam mengenali teks pada gambar plat nomor kendaraan yang diambil menggunakan kamera digital. Dataset yang digunakan terdiri dari 10 gambar plat nomor kendaraan dengan karakteristik gambar lalu lintas kendaraan, termasuk pencahayaan rendah, distorsi perspektif, noise, dan ukuran gambar yang kecil. Berbagai teknik perbaikan kualitas gambar diterapkan, seperti Contrast Limited Adaptive Histogram Equalization (CLAHE), Bilateral Filtering, Wavelet Denoising, Unsharp Masking, dan Super-Resolution GAN menggunakan bicubic interpolation. Pengukuran akurasi dilakukan menggunakan dua metrik utama, yaitu Character Accuracy Rate (CAR) dan Word Accuracy Rate (WAR), dengan nilai rata-rata masing-masing sebesar 96,91% dan 90,00%. Hasil penelitian menunjukkan bahwa metode perbaikan kualitas gambar mampu meningkatkan visibilitas karakter pada plat nomor, sehingga OCR dapat mengenali teks dengan akurasi tinggi meskipun terdapat noise dan distorsi pada gambar. Penelitian ini memberikan wawasan tentang efektivitas pipeline perbaikan gambar dan OCR pada kondisi lalu lintas kendaraan, serta menjadi landasan untuk pengembangan sistem pengenalan plat nomor yang lebih baik
