Abstract

Covid-19 is a pandemic that occurs in various parts of the world and is a form of public concern. Coronavirus Disease (Covid-19) is a mutation of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) which is highly infectious. The use of masks, keeping a distance and monitoring body temperature are ways that can be done to prevent the transmission of the Covid-19 virus. Many people have to give up their lives because of their ignorance of the dangers of this virus. Based on this, the authors try to develop a system that is able to detect and monitor automatically. That is by applying the use of mask detection and monitoring human body temperature before entering the room. The design of this detection system uses a webcam connected to a raspberry pi and a GY-906 Temperature Sensor and a HC-SR04 Proximity Sensor that is connected to an arduino nano. The way this detection system works is that the system can find out whether the user is wearing a mask or not and the user can find out his body temperature before entering the room. Besides, the output of this detection system is in the form of a display on the monitor and LCD as well as supporting outputs such as LEDs and Buzzers.ABSTRAKCovid-19 merupakan pandemi yang terjadi di berbagai belahan dunia dan merupakan bentuk kepedulian masyarakat.

Abstract

The availability of renewable energy sources of electricity, namely Solar Power Plants (PLTS) can be the main source of electricity for BSF Maggot cultivators, the majority of whom are still starting their maggot cultivation business. Maggot itself is a black soldier fly (BSF) larva or with its Latin name Hermetia illucens which in the body of this larva also contains a lot of antibiotics, high protein content, which is around 30-45%, so it is often used as animal feed. The purpose of this study is to make it easier to monitor the drying system on maggot with (IoT) so that the temperature used in the drying process can be detected as quickly as possible if there is an increase in temperature so that the driving motor is not damaged quickly. The BSF/maggot fly larvae don't last long when they are wet, so they need a maggot drying machine to dry the BSF/maggot fly larvae so that they last longer and increase the selling price of the maggot. To find out the temperature on the maggot drying machine, it is necessary to monitor or monitor temperature using the Internet of Things (IoT). to reduce the risk of damage to the machine. ABSTRAK Tersedianya sumber listrik energi terbarukan yaitu Pembangkit Listrik Tenaga Surya (PLTS) dapat menjadi sumber listrik utama para pembudidaya Maggot BSF yang mayoritas masih dalam merintis usaha budidaya maggot. Maggot sendiri merupakan larva lalat black soldier fly (BSF) atau dengan nama latinnya Hermetia illucens yang di dalam tubuh larva ini juga banyak mengandung antibiotic, kandungan protein yang tinggi, yakni sekitar 30-45% sehingga sering dimanfaatkan sebagai pakan ternak.Tujuan dari penelitian ini adalah  untuk mempermudah dalam memonitoring sistim pengeringan pada maggot dengan (IoT) agar suhu yang digunakan pada proses pengeringan bisa dapat di deteksi secepat mungkin jika terjadi kenaikan suhu  sehingga motor penggerak tidak cepat rusak. Larva lalat BSF/maggot ini tidak tahan lama apabila dalam  keadaan basah sehingga memerlukan mesin pengering maggot untuk mengeringkan larva lalat BSF/maggot ini agar tahan lama dan meningkatkan harga jual maggot tersebut. Untuk mengetahui temperature pada mesin pengering maggot diperlukan pemantauan atau memonitoring suhu dengan menggunakan Internet of Thing (IoT) apabila suatu saat terjadi troble atau masalah pada mesin pengering maggot yang sedang bekerja dan posisi alat berada pada jarak yang jauh maka dapat bisa langsung mematikan alat melalui handphone untuk mengurangi resiko kerusakan pada mesin

Abstract

Makassar is the center of government and business center in the province of South Sulawesi. The people of Makassar has a very high dependence on the use of electrical energy to meet their daily needs, both at home and at offices. The use of electrical energy which is quite high will cause an increase in customer bills every month. Therefore, this problem needs to be reduced by utilizing alternative energy sources. PLTS on grid is one of the solutions to reduce dependence on electrical energy from PLN. This research was carried out using a load simulation method based on the level of solar radiation in Makassar City at an installed power of 4500 VA. By using PLTS on grid the customer has two sources of electrical energy, from solar power and PLN line. The main source of electrical energy during the day is from on grid solar power and at night is from PLN line. If the power from the on grid solar power the day is insufficient to serve the load needs, PLN will automatically responsible for the electric power of the load. The simulation results show that the use of on-grid PLTS saves PLN's electricity consumption by 34.78% to 89.53%. These results illustrate that the potential for using on grid solar panels in the city of Makassar is very large

Abstract

Calculating the total impedance between two points that are equivalent and connected to a current voltage source still revolves around the discussion using the Wye-Delta transformation, the theory of the Series-Parallel formula, the loop current method and the node or node voltage method. These calculations are still ineffective and take quite a long time for certain complex circuits, because the calculations can only be done manually. So we need a special solution to facilitate us in the calculation process. In this case it is necessary to do a new transformation approach called Transformation [C]. This [C] Transformation Matrix will connect the old and new equivalent circuits. This study uses the Borland C++ Builder program with four kinds of complex circuit conditions tested. From the test results it can be seen that the results of program calculations are the same as the results of manual calculations and are proven to be easier, more effective and efficient than manual calculations which are complicated and require a long and lengthy calculation process. This software is very helpful and can be applied to calculate the total impedance of an electrical circuit system, especially in certain cases of conditioned complicated circuits.

Abstract

The electrical quality, especially voltage fluctuations, is very important to remain stable in supplying voltage to consumers. PT. PLN (Persero) has a minimum voltage limit of -5% and a maximum of +10% which is regulated in the Minister of Energy and Mineral Resources no. 3 of 2007 in the transmission system. However, the 150 KV transmission system often experiences voltage drops caused by conductors that are too long and inappropriate loads, so that in maintaining good transmission quality, a reliable system is needed. One of them is GI Cerme which has a double busbar type, which separates the two Java-Bali transmission sub-systems and is connected to supplies from West Surabaya GI and Lamongan GI. Even so, the Lamongan-Cerme network with a length of 26.77KMS and transformer load causes a voltage drop, in the case that occurred in April 2023 at GI Cerme at peak load it experienced a voltage drop of up to 137 KV, so it is necessary to overcome the voltage drop problem the transmission system was repaired at GI Cerme. Through the digsilent application, it is possible to simulate better system planning at GI Cerme so that the voltage can be repaired according to standards.
