Abstract

Abstract: The radar network system requires high-cost frequency, the complex configuration component of the electromagnetic feeding network circuit to make four output antenna with the same power and different phase output specifically for SIL (Self Injection Locked) Radar, and inexpensive material, especially for the electromagnetic component. 2.4 GHz Square Ring Patch with Ring Slot Microstrip Antenna with four output that has the same power using power divider and 90-degree phase different output for SIL Radar. this is the novel shaped microstrip Antenna with the free frequency, more unassuming configuration, and inexpensive material at the 2.4 GHz for SIL Radar. This system is an important part component of SIL Radar that is package consists of a 2.4 GHz Microstrip antenna with the Square Ring Patch with Ring Slot, double power divider which is double input with quad output with the same power and directional coupler 90-degree phase difference with two input and two output. The Antenna has single band and narrow bandwidth with the frequency is 2.38 GHz until 2.43 GHz under -10dB S parameter and frequency resonance 2.4 GHz, the radiation pattern is directional and the gain is 8.37 dBi, The Power divider has S parameter 2 port output of one part under -20dB at 2.4 GHz and isolation above -4dB that is all good agreement. The 90-degree hybrid coupler has S35 of -35.95dB, S46 of 35.09, S53 of -3.47, and S64 of -3.39 that all is qualified good operation. And overall size of the proposed antenna system is 100 mm times 55.7 mm with FR4 (Phenolic White Paper) with a dielectric constant is 4.4 that has 50ohm.DOI : https://doi.org/10.26905/jeemecs.v2i2.3253

Abstract

Tomato plants are one of the many agricultural commodities needed by the community. Most farmers grow tomatoes in conventional ways in the fields, fields or plantations without the control and measurement relying on experience and habitual factors, so the need for pH and temperature of the planting space of tomato plants cannot be given according to their needs, while the pH requirements of tomato plants range 6.5 and the planting room temperature is 28 °C, and soil moisture is 70%, using the hydroponic planting method which is automatically controlled by the Arduino-based microcontroller with the application of fuzzy mamdani making it easy to do pH setting of planting media using soil pH sensor as input and temperature of planting room using LM35 temperature sensor, and soil moisture sensor using humidity sensor fc28, as the system output fan and selenoid valve are used. To find out plant nutrition, one of the indicators is the pH value of soil media, room temperature and humidity of the planting medium.

Abstract

Perkembangan teknologi terutama panel surya sangat dibutuhkan dalam dunia industri maupun pendidikan, dengan adanya panel surya diharapkan dapat menjadi energi alternatif dalam menghasilkan arus listrik. Program pelatihan kemitraan masyarakat (PKM) ini bertujuan untuk mengenalkan proses terjadinya panel surya kepada siswa Sekolah Menengah Pertama Bani Hasyim dan memberikan contoh panel surya sehingga dapat digunakan oleh pihak sekolah. Kegiatan ini diikuti oleh 15 orang peserta terdiri dari siswa dan siswi SMP Bani Hasyim. Pelatihan dilakukan dalam kurun waktu satu hari, pada tanggal 1 April 2022. Metode pelaksanaan pengabdian yaitu sosialisasi dan praktik penggunaan alat panel surya. Pelaksanaan terdiri dari tiga tahap, yaitu perencanaan, pelaksanaan, dan evaluasi. Setelah PKM dilaksanakan, terjadi peningkatan pemahaman siswa SMP Bani Hasyim mengenai proses terbentuknya panel surya. Dengan pengetahuan ini, siswa mampu menggunakan panel surya dengan memanfaatkan energi alternatif yang digunakan di sekolah.
