Abstract

AbstrakSistem irigasi semiotomatis merupakan salah satu dari industri pertanian dengan menggunakan mesin-mesin elektronik. Sistem irigasi semiotomatis untuk ukuran lahan 10x20 meter memerlukan daya 376,3 Wh setiap harinya. Pertanian yang berada di tempat terpencil dan tidak terjangkau jaringan listrik maka diperlukan sumber lisrik independen, yang mana pada skripsi ini menggunakan energi surya. Energi surya atau matahari dipilih dengan alasan melimpahnya energi surya di Indonesia.Energi surya dapat diubah menjadi energi listrik dengan menggunakan panel surya. Energi listrik yang dihasilkan panel surya tidak dapat digunakan secara langsung oleh setiap mesin pada sistem irigasi semiotomatis. Tegangan keluaran dan arus keluaran dari panel surya bervariasi tergantung pada tingkat intensitas cahaya matahari. Maka dari itu solar charge controller atau baterai regulator digunakan sebagai filter tegangan output panel surya. Selain sebagai filter, baterai regulator juga digunakan sebagai pembatas dari tingkat pengisian baterai.Pada saat malam hari panel surya tidak dapat menghasilkan energi listrik karena  cahaya matahari tidak bersinar, maka dari itu diperlukannya baterai. Baterai merupakan komponen yang berfungsi untuk menyimpan energi listrik. Baterai diperlukan dalam sistem pada panel surya supaya sistem dapat bekerja pada saat malam hari sehingga sistem dapat bekerja selama dua puluh empat jam. Pada sistem daya irigasi semiotomatis memerlukanDC to AC Inverter sebagai pengubah tegangan DC menjadi tegangan AC supaya dapat digunakan oleh beban dengan tegangan AC.Kata Kunci : Panel surya, Solar charge controller, Baterai, Inverter DC ke ACAbstract  Semi-automatic irrigation system is one of the agricultural industries using electronic machines. A semi-automatic irrigation system for a land size of 10x20 meters requires 376.3 Wh of power every day. Farms located in remote areas and inaccessible to the electricity grid require an independent source of electricity, which in this thesis uses solar energy. Solar energy was chosen on the grounds of the abundance of solar energy in Indonesia.Solar energy can be converted into electrical energy by using solar panels. The electrical energy generated by solar panels cannot be used directly by each machine in a semi-automatic irrigation system. The output voltage and output current of the solar panel varies depending on the level of sunlight intensity. Therefore, the solar charge controller is used as a filter for the solar panel output voltage. Apart from being a filter, the solar charge controller is also used as a limiter of the battery charge level.At night solar panels cannot produce electrical energy because the sun's light does not shine, therefore batteries are needed. Batteries are components that function to store electrical energy. Batteries are needed in the solar panel system so that the system can work at night so the system can work for twenty four hours. In a semi-automatic irrigation power system requires a DC to AC Inverter as a converter of DC voltage into AC voltage so that it can be used by loads with AC voltage.Index Terms : Solar panel, Solar charge controller, Baterry, DC to AC Inverter.

Abstract

ABSTRAKBencana alam seperti banjir, tanah longsor dan angin puting beliung merupakan beberapa kejadian alam yang seringterjadi di Indonesia,dan penanganan bencana yang dilakukan oleh pemerintah selalu terkendala dengan waktu, dana, danakses lokasi kejadian. Pemerintah sendiri bergerak berdasarkan informasi yang didapatkan dari wilayah sekitar yang terkaitdan daerah dimana bencana tersebut terjadi. Karena cakupan wilayah Indonesia sangat luas maka kecepatan dan ketepatandalam pengumpulan informasi sangatlah penting untuk penanganan bencana, salah satu solusi yang ada adalah denganmemanfaatkan jaringan internet, terkhusus dengan Wireless Sensor Network (WSN). Penelitian ini membahas tentangperancangan routing protocol WSN yang menerakpan metode Fuzzy Sugeno dalam simulasi berbasis aplikasi Matlabdengan mensimulasikan sejumlah node pada wilayah tertentu. Pertama, dengan routing protocol indicator-based setiapnode menyusun indikatornya masing-masing untuk membantu prosen routing. Kemudian dengan menerapkan fungsikeanggotaan, setiap node dapat menentukan Cluster Head (CH) nya masing-masing sesuai hasil pembobotannya. Kedua,dengan metode Fuzzy Sugeno, setiap node akan menentukan rute pengiriman data paling efisien untuk dapat menghematdaya dan waktu sehingga sampai pada sink. Hasil yang didapat dari penelitian ini adalah dengan 50 node bercakupan 200m 2 yang tersebar dalam wilayah 500 m 2 , jumlah cycle maksimum adalah 1000 cycle, dan sink berada di tengah area.Seluruh packet informasi diterima saat putaran ke-282 atau dalam wahtu 4 menit 42 detik. Rata-rata maksimal penggunaandaya setiap node adalah 13 mAh (dengan asumsi setiap node berkapasitas 100mAh) dan berkurang seiring putaran yangterjdi karena semakin sedikit node yang aktif dalam sistem.Kata kunci: wireless sensor network, routing protocol, indicator-based, fuzzy sugeno.ABSTRACTNatural disasters such as floods, landslides and hurricanes are some of the natural events that often occur inIndonesia, and disaster management carried out by the government is always constrained by time, funds, and access to thelocation of the incident. The government itself moves based on information obtained from the surrounding area and thearea where the disaster occurred. Because the coverage area of ​​Indonesia is very wide, the speed and accuracy incollecting information is very important for disaster management, one of the existing solutions is to utilize the internetnetwork, especially the Wireless Sensor Network (WSN). This study discusses the design of the WSN routing protocol thatapplies the Fuzzy Sugeno method in a simulation based on the Matlab application by simulating a number of nodes in acertain area. First, with an indicator-based routing protocol, each node compiles its own indicators to assist the routingprocess. Then by applying the membership function, each node can determine its respective Cluster Head (CH) accordingto its weighting results. Second, with the Fuzzy Sugeno method, each node will determine the most efficient datatransmission route to save power and time so that it arrives at the sink. The results obtained from this study are 50 nodescovering 200 m2 spread over an area of ​​500 m2, the maximum number of cycles is 1000 cycles, and the sink is in themiddle of the area. All information packets are received during the 282nd round or within 4 minutes 42 seconds. Themaximum average power usage of each node is 13 mAh (assuming each node has a capacity of 100mAh) and decreaseswith rotation as there are fewer active nodes in the system.Keyword: wireless sensor network, routing protocol, indicator-based, fuzzy Sugeno.

Abstract

LoRa is one of the most popular LPWAN technologies. LoRa technology is suitable for IoT application scenarios that only need to transmit small amounts of data over long distances and transmit data at low power. The tool system for monitoring hospital patients aims to help and speed up medical records of health services, both under normal circumstances and in critical or urgent situations. LoRa functions as a long-range spectrum communication medium to receive data sent from the detector subsistence. This research focuses on testing Heltec's LoRa range at 923MHz frequency. The parameters used are Received Signal Strength Indicator (RSSI) and Packet loss. The RSSI test results will be compared with the RSSI calculated using the normal log shadowing model. Calculations for the free space area with the addition of shadowing effects. Judging from the range of RSSI values at each test point, RSSI is relatively stable. However, based on the average RSSI testing and calculations, RSSI has decreased while packet 2 loss has increased with each additional distance. From this study, the maximum LoRa range is 180 meters. Keywords: LoRa, IoT, RSSI

Abstract

Goods delivery services are service to handle all activities necessary for thedelivery and receipt of goods intended to represent the interests of the owner of thegoods. However, currently to determine the shipping rate of goods is still usingtheconventional method, namely by first weighing the goods to find out the weight of thegoods and measuring the length, width, and height to find out the volume of the goods, then accessing the database on the computer to find the shipping rates fromone city to another. After that, do manual calculations using a calculator on the weight of goods and intercity rates to get the total freight rate. Based on the problems previously described, a tool is needed to speed up the process of setting shipping rates to be more ef ective and ef icient. In this study, the design of digital scales was carried out with the measurement of object volume and calculation of shipping rates for goods delivery services based on ESP32.
