Abstract

UPT Balai Yasa Surabaya Gubeng has electrical equipment with non-liner load characteristics, which may affect power rating in accordance with PLN and IEEE 519 – 2014 standards. Non-linear loads result in non-compliant power quality parameter values ​​such as voltage, power factor, frequency, and harmonics. The efficiency of the transformer is also determined. due to the generated power from the transformer to the load. This study was conducted by collecting and processing data from LVMDP. It was found that several parameters did not comply with PLN standards. The power factor of LVMDP 1 MVA and LVMDP 200 KVA are 0.8 and 0.7 respectively. Meanwhile, all voltage and frequency ​​of 1 MVA and 200 KVA LVMDP are still according to PLN standards. Whereas, the harmonics of LVMDP 1 MVA THDi R phase (26.18%), S phase (18.83%), THDv T phase (8.86%), and LVMDP 200 KVA THDv T phase (5.58%) are not in accordance with IEEE 519 – 2014 standards. Thus, single tuned filter were simulated which reduce the harmonics of the systems and increase the efficiency of the transformator.

Abstract

Juanda Airport Access Road, Sidoarjo Regency, East Java has a length of 3.15km with a width of 6m and there are 73 lighting points with a pole height of 12m and a distance between poles of 44m with a total of 8 single-arm poles and 65 double-arm poles. In addition, the street lighting lamps installed are 72 150 watt LED lamps and 66 250 watt SON-T type lamps. The measurement results are 26.37 lux for a 150 watt LED type lamp and 10.27 lux for a 250 watt SON-T lamp. However, from the many lights that have been installed, the lighting on the access road to Juanda Airport is still not optimal and many blackspots are found in certain areas. Therefore, it is necessary to do a re-analysis so that the road lighting for the Juanda Airport access road can meet the standards. The results of the analysis concluded that by carrying out a simulation on the dialux application according to the conditions in the field, 73 points of lighting poles were needed, the handlebar angle of the ornament was 14.06o with a total of 138 196 watt LED lights with an intensity of 15 lux which was in accordance with the standards of the Indonesian National Standards Agency 7391 : 2008 regarding the specifications for street lighting in urban areas and the Ministry of Energy and Mineral Resources 2014 for collector road classes for national road status, namely 15 - 20lux.

Abstract

Balongmojo Village is an entrepreneurial village in Mojokerto that has great potential in the livestock sector, especially catfish cultivation. The community service carried out aims to increase the productivity and sustainability of fisheries businesses in the village through the application of simple and environmentally friendly technology. Community service activities carried out include: (1) development of alternative feed based on agricultural waste (tofu dregs) for catfish; (2) making probiotics to improve catfish health; (3) managing catfish pond waste into liquid fertilizer; and (4) implementing an IoT-based automatic feeding system. The results of the study showed that the application of this technology was able to improve the quality of pond water and the growth of catfish. In addition, the use of organic waste also contributes to increasing soil fertility and reducing environmental pollution. Overall, this community service program has had a positive impact on improving the welfare of the Balongmojo Village community through increasing income, improving the environment, and developing community capacity in adopting modern technology.

Abstract

Penelitian ini mengusulkan pendekatan baru dalam pemanfaatan kecerdasan buatan untuk mengklasifikasikan kondisi aman atau bahaya berdasarkan citra thermal, yang sebelumnya belum pernah diterapkan. Proses dimulai dengan melakukan ekstraksi fitur dari citra thermal, yang bertujuan untuk menghitung persentase area berwarna putih serta area dengan warna selain putih. Informasi ini dijadikan dasar untuk proses klasifikasi lebih lanjut. Sebanyak 10 citra thermal digunakan sebagai data latih untuk membentuk model klasifikasi, sementara 2 citra lainnya digunakan sebagai data uji guna mengukur performa sistem. Metode yang digunakan dalam penelitian ini adalah jaringan saraf tiruan (JST) dengan arsitektur single perceptron. Proses pelatihan dilakukan sebanyak enam kali iterasi. Namun, hasil menunjukkan bahwa penyesuaian bobot sudah mencapai kestabilan bahkan pada iterasi pertama. Hal tersebut menunjukkan bahwa model belajar dengan cepat berdasarkan data pelatihan. Model JST yang telah dilatih ini kemudian digunakan untuk menguji kemampuan klasifikasi terhadap data baru. Hasil pengujian menunjukkan tingkat akurasi yang sangat tinggi, yaitu mencapai 100% dalam mengidentifikasi kondisi pada citra thermal termasuk kategori aman atau berbahaya. Hal ini menunjukkan bahwa pendekatan berbasis JST sederhana sekalipun mampu memberikan performa klasifikasi yang sangat baik jika fitur yang digunakan cukup representatif. ecara keseluruhan, penelitian ini membuktikan bahwa kombinasi antara ekstraksi fitur sederhana dan algoritma pembelajaran mesin dasar dapat secara efektif mendeteksi potensi bahaya dari citra thermal, serta membuka peluang untuk pengembangan sistem pemantauan otomatis berbasis visual thermal di masa depan.
