<![CDATA[The rainfall in the Cilacap region is high, about 80-100mm in October-March. The high rainfall that causes the overflow of river water is unpredictable. The high water discharge is not realized until the river water overflows and causes flooding. Therefore, a river water level monitoring system is needed to detect river overflows early. This tool uses a solar cell as a power supply. The monitoring system is divided into two points of river water level monitoring system with a distance between points for the laboratory scale stage, which is 100 meters. Sensors that measure the height of river flow are ultrasonic sensors. The sensor results are processed by microcontroller and SIM 900 L module to be sent to the database. When the water level is in the Alert level 3, the buzzer will sound as a warning. The ultrasonic sensor test results have a very small error. Sensor 1 has an average error of 0.00023% and ultrasonic sensor 2 has an error of 0.00016%. The system is able to transmit river water level data that can be accessed through the website.]]>

<![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[Banjarwaru Village is located in Nusa Wungu District and has several hamlets connected to the main road as access to transportation facilities. The lack of street lighting hampers the activities of village residents, especially at night. Road points that do not have public street lighting are far from residents' homes, so they cannot use PLN electricity sources. Seeing the conditions explained above, the need for technology with energy sources that utilize renewable energy such as solar power to supply power to public street lights has been widely implemented. Making street lights with a solar power supply with the application of modern technology is the main priority in this community service activity. The main target objective of this Community Service is the Public Street Lighting Program through the manufacture of street lights with power supply from solar energy. The implementation method in this service is through observation and experiments in the field in the process of designing and manufacturing public street lights and handing over technology transfer to the community. The results of making public street lights with solar energy supply using Arduino Mega which functions to receive data from the LDR sensor and is continued with testing battery charging with solar power. The installation of the LDR sensor will help the efficiency of the lights because it will control the lights to turn on automatically. The results of the manufacture of public street lights also provided assistance and training to the Banjarwaru Village community regarding how the equipment works and the repair process if problems arise in the future.]]>

<![CDATA[Technological developments in materials are increasingly evolving, one form of development is the type of composite insulation. One of the natural fiber composites currently available is a composite from palm fiber which provides increased dielectric strength. Partial discharge due to voids in the composite results in structures such as electrical treeing due to changes in the properties and morphology of the composite causing increased insulation failure and disrupting power distribution. This research tested the strength of Epoxy composite insulation and palm leaf ash filler. By combining these two materials, a complementary composite insulating material will be formed to prevent electrical treeing. The results of the research show that the composite insulating material with nipa palm fiber as filler has an average breakdown voltage value of 40 kV and is above the standard breakdown voltage value for medium voltage insulators of 30 kV. The addition of more and more palm leaf ash filling material will produce voids, thereby accelerating the occurrence of electrical treeing and decreasing the breakdown voltage of the insulation.]]>
