Abstract

Bermain layang-layang disekitar saluran transmisi dilarang, Hal itu tertuang dalam PerMen ESDM Nomor 02 Tahun 2019 tentang Ruang Bebas dan Jarak Bebas Minimum yang diijinkan pada Saluran Udara Jaringan Listrik. Untuk membersihkan layang-layang dengan cara konvensional mengharuskan tim pemeliharaan menggunakan tongkat pembersih sampah yang menyangkut di jaringan konduktor atau cara tertentu lainnya. Alat tersebut berguna untuk membakar sampah layang-layang yang tersangkut pada saluran transmisi yang pengendaliannya menggunakan dua Controller yaitu transmitter dan receiver dengan arduino sebagai pusat kontrol. Hasil dari penelitian ini menunjukan bahwa berdasarkan hasil pengujian, hingga jarak 20 meter drone flamethrower ini dapat mengirim dan menerima perintah sesuai dengan yang diinginkan dan berhasil membakar layang-layang pada jaringan sistem tenaga listrik dengan ketinggian 17 meter dan rata-rata waktu pembakaran untuk membakar 1 layang-layang selama 13 detik. Maka dapat disimpulkan bahwa perancangan alat drone flamethrower dapat berjalan dengan baik.

Abstract

Concentrated latex is a processed natural rubber product with a dry rubber content of 60-64%. Making concentrated latex by centrifugation requires investment in expensive equipment, while making concentrated latex by creaming takes a long time, around 2-3 weeks. One way to speed up the production of concentrated latex is by using a simple tool, namely an orbital vibrator. This research used a Randomized Block Design with 2 factors. Factor I is Vibration Time (V) and factor II is creaming Time (T). The results of the research showed that the length of shaking and creaming time in making concentrated latex had an influence on the yield and quality of concentrated latex except for the pH value, but there was no interaction between these two factors. The quality of concentrated latex that meets ISO 2004 standards is pH (10.1-10.83) and WKM (564.33-618.17 seconds) while KKK (53.74 - 57.64%) and KJP (50.58 – 53.29 %), not yet meeting ISO 2004 standards.

Abstract

Mount Everest, one of PT's mining areas. ANTAM Tbk. UBPN Southeast Sulawesi. To find out the actual mining tonnage, it is done in two ways, namely the weighing method and the truck counting method. The weighing method is applied to high-grade saprolite ore (HGSO) material with Ni content ≥ 1.80%, while the truck counting method is applied to two materials, namely low-grade saprolite ore (LGSO) with a content of 1, 50% ≤ Ni < 1.80% and overburden material (OB). This survey was conducted to compare the actual mining tonnage with the mining progress tonnage using the Mine Survey method. Calculation of the tonnage of the mine survey using the Surpac 6.3 software. Based on the results of the calculations carried out, the difference in the tonnage produced between the mining realization using the mine survey method, namely high-grade saprolite ore and low-grade saprolite ore material, shows that the actual mining tonnage is larger than that of the mine survey method of tailings material is that determined by the mine survey method Tonnage higher than the mining realization.

Abstract

Scholarships are financial assistance to support education that is often given to students, both for outstanding students and students who are economically disadvantaged. The distribution of tuition assistance generally aims to support underprivileged students so that they can attend education despite their lack of financial conditions. The Wonogiri Regency Government itself has prepared a scholarship program for outstanding students to boost human resource in the Wonogiri Regency. In Wonogiri Regency itself, many outstanding students need scholarship assistence, but they still have difficulty getting information about the program due to the lack of information media that has not been supported. The research method used is teh rapid application development (RAD) method. This research aims to design an Android-based scholarship information system application that is expected to help make it easier for students to get information and register for scholarships online without having to come to the registration location.

Abstract

Sweet corn (Zea mays L. saccharata Sturt) is one type of annual crop whose life cycle is only 80 - 150 days. This study aims to determine the growth and production of sweet corn (Zea mays L. saccharata Sturt) due to the application of cow manure and banana peel liquid organic fertilizer. This research was conducted from March to July 2023. This study used a Factorial Randomized Group Design with 2 factors studied and 3 replications where the first factor was cow manure (K) consisting of 3 levels, namely K0 = 0 tons/ha (control), K1 = 15 tons/ha, K2 = 30 tons/ha. The second factor is banana peel liquid organic fertilizer (P) which consists of 4 levels, namely P0 = 0% (control), P1 = 10% / 1 litre of water, P2 = 20% / 1 litre of water, P3 = 30% / 1 litre of water. The results showed that the application of cow manure had a very significant effect on the parameters of plant height, leaf area, length of husked cob, diameter of husked cob and weight of husked cob per sample and had a significant effect on weight of husked cob per plot. The application of banana peel liquid organic fertilizer has a significant effect on the diameter of the husked cob but had no significant effect on the parameters of plant height, leaf area, length of husked cob, weight of husked cob per sample and weight of husked cob per plot. The interaction between cow manure and banana peel liquid organic fertilizer had no significant effect on all parameters observed.

Abstract

Started with the frequent running out of backup battery power at the Wifi Base Transceiver Station (BTS) due to frequent power outages in the BTS area and the high temperature inside the panel box. This problem can be overcome by research into a panel box temperature monitoring system and battery charging voltage in IoT-based BTS. The system development used is a prototype method, which can overcome problems between users and researchers. Researchers used ESP32 Wrover as a microcontroller, voltage divider as a voltage sensor and DHT11 as a temperature sensor. If the charging voltage is less than 11 volts and/or the voltage is more than 15 volts then the ESP32 Wrover will send a Telegram message to the user and if the temperature read by the DHT11 sensor is more than 40 degrees Celsius then the system will turn on the relay connected to the cooling fan, the fan will be turned off when the temperature drops to 30 degrees Celsius.
