<![CDATA[One of the problems with internet networks in rural areas is the difficulty of connecting cable-based internet because the distance is too far, wireless/wireless-based internet networks can be an alternative solution to these problems. A research analysis of the Power Link Budget calculation was carried out in planning the outdoor wireless internet network in the village. Kutanagara Garut. The test was carried out using the Power Link Budget calculation method and simulation using the Ubiquiti ISP Design Center application with a LiteAP GPS transmitter device and a NanoBeam 5AC receiver. Network planning is made using the Point to Point (PTP) system in the 5725 MHz frequency band to be precise at 5725 MHz Sub Band NII-3. The parameters tested are SOM (EIRP, margin signal), free space loss (FSL), Fresnel zone clearance (FZC), coverage area, signal strength obtained and internet speed capacity. The results of the calculations and configurations show that the EIRP value of the sender is 36 dBm, the EIRP of the receiver is 36 dBm, the maximum bandwidth is 20 MHz, Fresnel zone clearance is 3.4 m and the received signal strength is -49 dBm. These results have met the standards set by KOMINFO and a network design can be made. The results of the network simulation show that the internet network design has covered the entire area of Kutanagara Garut Village with an estimated signal obtained is -49 dBm, with a signal margin of 46.2 dB which already meets the standards of TIPHON with network classification included in the outstanding category (very good). Has a maximum internet capacity of 147 Mbps consisting of 74 Mbps download speed and 74 Mbps upload speed]]>

<![CDATA[In telecommunications, filters are devices that play an important role in a telecommunications system. One of them is a bandpass filter that can pass signals with a passband frequency and cut off the stopband frequency. In the process, various kinds of signal interference will be found that can interfere with the quality of electromagnetic waves. This research will design and realize a microstrip bandpass filter that can pass the 6 GHz frequency with a minimum bandwidth of ? 100 MHz for C-Band Radar applications. This filter is designed using a square open loop resonator which will be simulated using the CST studio suite 2019 which will be realized using a 4-epoxy FR substrate. In this study the design of a microstrip bandpass filter was carried out with three stages of design simulation to determine the characteristics of the square open loop resonator, split ring resonator, and defected ground structure design. Based on the results of the final design of the microstrip bandpass filter design, the simulation results obtained work at a resonant frequency of 6 GHz with a return loss value of -32.098 dB, an insertion loss value of -0.40148 dB and a bandwidth of 97.3 MHz. The results of bandpass filter fabrication measurements were obtained at a resonant frequency of 6 GHz, the results obtained were in accordance with the required specifications with a return loss of -29.09 dB, an insertion loss of -2.75 dB with a bandwidth of 485.4 MHz.]]>

<![CDATA[Saat ini sistem keamanan merupakan hal terpenting dalam kehidupan sehari – hari, seperti sistem keamanan loker di kampus atau sekolah. Banyak sekali terjadi aksi pencurian yang di karenakan sistem keamanan tidak terproteksi dengan baik. Biasanya loker-loker saat ini hanya menggunakan kunci konvensional. Penggunaan kunci konvensional kurang praktis pada zaman sekarang, karena kunci tersebut masih bisa diperbanyak. Sistem keamanan dengan kunci konvensional juga sering terjadi pada keberadaan kunci tersebut. Terkadang kita lupa menaruh atau tak sengaja jatuh lalu kemudian hilang. Kurangnya pengawasan pada loker konvensional juga menimbulkan kemungkinan terjadi pembobolan secara paksa tanpa sepengetahuan pemilik loker. Pada penelitian tugas akhir ini menggunakan mikrokontroller Raspberry Pi type 3 yang mendapat data dari hasil rekaman Webcam Logitech untuk menggerakan relay dan selenoid. Sistem ini juga dilengkapi dengan tampilan check in, check out dan buka loker yang ditampilkan pada LCD supaya mudah dan siapapun bisa mengakses. Dari hasil penelitian yang dilakukan jika semua komponen bekerja dengan baik maka diperoleh nilai kesensitifan kamera sebesar 60 % dari 20 kali percobaan.]]>

<![CDATA[Banjir merupakan bencana alam yang harus di waspadai oleh masyarakat sekitar aliran sungai. Fenomena bencana banjir sering menyebabkan kerusakan harta benda bahkan sampai merenggut korban jiwa [1]. Banjir disebabkan oleh daerah resapan atau saluran air yang tidak berfungsi dengan baik, serta adanya intensitas curah hujan yang tinggi menyebabkan aliran masuk lebih besar dibandingkan aliran keluar [2]. Maka perlu dibuat media komunikasi yang dapat mengirimkan informasi kepada masyarakat jika akan ada banjir yang datang. Pengumpulan data pada daerah sekitar sungai seperti ketinggian aliran sungai, curah hujan di aliran sungai serta kelembaban udara dialiran sungai sangat diperlukan untuk dapat diolah sehingga dapat prediksi akan adanya banjirData – data tersebut diambil dengan menggunakan beberapa sensor seperti rain gauge (sensor curah hujan), anemometer (sensor kecepatan angin), sensor SR04T ( pendeteksi ketinggian air), sensor DHT11 ( sensor suhu dan kelembaban udara). Sensor tersebut diintegrasikan menggunakan arduino mega lalu di kirimkan datanya melalui modul gsm sim 800L. Data tersebut akan dikirimkan ke sistem cloud dan database, serta ditampilkan pada website. Sistem monitoring telah bekerja mengirimkan data – data yang diperlukan. Data – data tersebut menghasilkan bahwa saat keadaan hujan keadaan lingkungan disekitar sistem pernodenya mempunyai suhu 250C sampai 270C. Kelembaban 99 Rh, Ketinggian Air 102 cm sampai 104 cm, curah hujan 20 ml/s dan kecepatan angin antara 2 m/s sampai 6 m/s.]]>

<![CDATA[Today the use of gas cylinders is increasingly widespread in society. Starting from simple stalls, street vendors and many households use these gas cylinders. The impact that occurs is an increase in orders to producers to produce gas cylinders. With the increase in orders, it causes less attention to the safety side of gas cylinders. One side of security that is not given enough attention is gas leaks. This study aims to implement Internet of Things (IOT) concept by designing a tool that can be used to detect leaks using the MQ-2 gas sensor and android. This tool serves to provide leak notifications in the form of an alarm. The alarm will turn on automatically when the sensor detects gas that emits an odor so that it can be anticipated immediately. The test results show that this detector can work properly and optimally in giving gas cylinder leak warnings.]]>

<![CDATA[Indonesia merupakan negara dengan iklim tropis. Salah satu musim di Indonesia adalah musim hujan. Curah hujan yang sangat tinggi dapat menimbulkan bencana banjir di berbagai wilayah Indonesia yang menimbulkan kerugian akhir maupun korban jiwa. Sistem peringatan dini bencana banjir menjadi salah satu solusi agar masyarakat Indonesia dapat mempersiapkan diri sejak dini ketika terjadi bencana. Penelitian sebelumnya telah membuat sistem bencana banjir dengan menggunakan GSM 900, namun permasalahannya ada beberapa lokasi penempatan sistem bencana banjir yang kurang sinyal GSM atau tidak ada sinyal GSM sama sekali. ,. Nilai RSSI terkecil yang diperoleh sebesar -87 dBm dan nilai tertinggi sebesar -128 dBm. Sedangkan pada jarak Non Line of Sight, Lora hanya mampu menjangkau jarak 520 meter dengan nilai RSSI terkecil - 128 dan nilai RSSI terbesar yaitu -147 dBm. Hal ini membuktikan bahwa dibutuhkan banyak node saat menggunakan Lora karena Lora memiliki keterbatasan jarak untuk komunikasi transmisi data]]>

<![CDATA[Predictive maintenance can reduce the risk of sudden transformer failure which causes the risk of plant to stop operating. One of transformer predictive maintenance technique is the Dissolved Gas Analysis (DGA) Test Oil Transformer. The gas is interpreted and analyzed to find out and get conclusions about the health condition and also possible problems in the transformer based on IEEE Standards and IEC Standards. To facilitate monitoring, a Decision Support System for Interpretation of Test Results of DGA Oil Immersed Transformer was created to form a database containing transformer data with the amount of main gas from the DGA test results. Next, decision tree was made using the J48 algorithm. The decision tree simplifying and speed up the decision-making process for recommended actions that are displayed on the system. The system also displays a trending graph of the last transformer test and quickly displays a dashboard of transformer status, i.e. normal, alarm, or danger. Engineer will get notification email if any transformer is in danger status. In addition, the system is able to provide information on possible fault types for each transformer. The benefits of this system are that the health condition of the transformer can be monitored properly and corrective action can be taken immediately on a problem based on the results of the decision support system. This will reduce the risk of shutdown and support the reliability of plant operations.]]>

<![CDATA[The majority of the population of Banjarwaru Village are farmers. The price of fertilizer is getting higher from time to time while farmers need fertilizer for their plants. Problems arise when fertilizer shortages often occur. In addition, the type of fertilizer used is generally a type of chemical fertilizer that is not good for the human body because the substance can be carried into the food consumed. Organic fertilizer is one option to overcome this problem. This type of fertilizer is now starting to be widely available on the market, although the price is relatively expensive. The solution to this problem is that it can be done by making organic fertilizer independently. Another factor is that there is a lot of organic waste that can be processed into liquid organic fertilizer (POC). Therefore, to create a village that is independent in fertilizer, the PKM Team aims to create an organic fertilizer maker based on a PLTS electricity source and provide training in operating the tool. The method used is by making an organic liquid fertilizer maker, socializing it to residents of Banjarwaru Village, and training and demonstrating how to operate the tool.]]>

<![CDATA[Indonesia adalah salah satu negara yang beriklim tropis. Curah hujan yang tinggi menyebabkan banjir pada sungai yang tidak dapat diprediksi. Bencana banjir yang terjadi nampak tidak ada pencegahan secara efektif serta kurangnya sistem untuk memberikan peringatan sedini mungkin sebelum terjadinya bencana banjir agar kerugian dapat diminimalisir. Pemantauan bencana banjir harus dilakukan di tepi sungai dari hulu ke hilir. Pada lokasi tersebut sering tepi sungai berada di daerah hutan yang kondisi sinyal gsm lemah bahkan tidak ada. Kondisi tersebut menyebabkan sulitnya pengiriman data antar node ews ke penerima. Kesulitan tersebut dapat diatasi dengan menggunakan sebuah modul Lora. Lora mempunyai komunikasi menggunakan gelombang radio 455 Mhz. Gelombang tersebut dapat dipancarkan oleh modul dan dapat diterima oleh modul Lora di Reciver. Sehingga pengiriman data dapat dilakukan tanpa mengadalkan sinyal GSM. Lora juga dapat digunakan untuk pengiriman data menggunakan topologi jaringan seperti star, mesh, dll. Sistem peringatan dini bencana banjir menggunakan Lora didapatkan jarak maksimal komunikasi pada NLOS jarak maksmial komunikasi adalah 520 m dengan nilai RSSI terkecil -128 dan terbesar -147 dBm.]]>

<![CDATA[Rice is a staple food in Indonesia and globally, but its production is threatened by pests such as the brown planthopper. Conventional pest control methods, including pesticides and traditional techniques, often prove ineffective and have negative environmental impacts. Light traps have been explored as an alternative due to the brown planthopper's phototactic behavior, yet existing designs lack efficiency in capturing pests. This study presents an IoT-based solar-powered pest control system that integrates light as an attractant and an electric trap for effective pest elimination. The system features real-time monitoring of voltage, current, and light intensity using an LCD display, powered by a 35 Wp solar panel and managed through an Arduino Uno microcontroller. Experimental results show that brown planthoppers are most attracted to an LED light with an intensity of 780 lux, operating at 11.5 V and 0.97 A. The system consumes 112.52 Wh, with a full battery charge requiring approximately 6 hours and 7 minutes. These findings highlight the potential of a sustainable, energy-efficient solution for pest control in rice agriculture. ]]>
