Ketahanan ekonomi merupakan salah satu program yang gencar digaungkan pemerintah saat ini, terutama di masa pandemi Covid-19. Salah satu cara untuk meningkatkan ketahanan ekonomi masyarakat adalah melalui budidaya lele. Beberapa faktor pertimbangan dan pemilihan budidaya lele adalah lele merupakan salah satu jenis ikan yang banyak dikonsumsi masyarakat, mudah pemeliharaannya dan mempunyai daya tahan yang baik. Banyak cara budidaya lele salah satunya adalah dengan teknik bioflok. Teknik ini dapat meningkatkan keuntungan karena kebutuhan pakan lebih sedikit dan dapat dipelihara secara padat tebar. Kegiatan ini mencakup pembuatan kolam terpal dengan dimensi 1,5m x 2m x 0,6m sebanyak dua buah dan pelatihan budidaya lele. Hasil yang diperoleh dari kegiatan ini adalah 1) meningkatnya keterampilan mitra dalam budidaya lele; 2) hasil produksi yang baik, ditandai efisiensi pakan dengan Food Convertion Ratio (FCR) = 0,73; 3), estimasi pendapatan Rp. 333.571 dengan jumlah lele yang dipelihara sebanyak 3.000 ekor.

Running text has many benefits, not only can it provide beauty for a promotional media but also become a very effective promotional media and can be used for a business. In Duwet Village, there is a UMK that can produce several superior products, including corn rice (gerit), cassava crackers and bamboo crafts (besek). They need media that can be used for marketing media. With this problem, we propose running text maintenance training. Running text maintenance training for displaying information in Duwet Village is beneficial for the people there. This is due to the unavailability of running text in Duwet Village UMK. With the running text, it is expected to be able to socialize and market superior products when there are guests from outside who visit Duwet Village

Kebutuhan energi listrik domestik mayoritas berbentuk gelombang sinusoida pada frekuensi 50 Hz. Sumber energi terbarukan mayoritas berbentuk dc atau daya dengan frekuensi tidak terkontrol. Untuk itu diperlukan alat yang dapat mengontrol bentuk gelombang dan frekuensinya. Alat ini disebut inverter. Inti dari inverter sinusoida terletak pada kontrol switching, dimana bentuk gelombang dan frekuensi ditentukan pada alat kontrol ini, salah satunya adalah gelombang SPWM. Dipasaran tersedia pembangkit SPWM seri EGS-002, modul ini beroperasi pada frekuensi tetap 50 HZ atau 60 Hz, sehingga tidak bisa digunakan untuk membangkitkan daya listrik dengan frekuensi yang variabel. Untuk itu dilakukan penelitian ini, tahap awal adalah membuat pembangkit SPWM berbasiskan arduino dengan spesifikasi semirip mungkin dengan EGS-002. Sistem yang dibangun terdiri dari arduino uno sebagai pembangkit sinyal SPWM, driver IR-2110 sebagai penyedia tegangan mengambang (bootstrap) untuk transistor MOSFET tipe-N IRZF44N pada rangkaian H-bridge. Hasil yang didapatkan adalah mikrokontroller arduino uno bisa membangkitkan sinyal SPWM dengan hasil berupa gelombang sinusoida murni dengan frekuensi 50 Hz. Domestic electrical energy needs are in the form of sinusoidal waves at a frequency of 50 Hz. The majority of renewable energy sources are in the form of dc or power with uncontrolled frequency. For that we need a tool that can control the waveform and frequency. This device is called an inverter. The essence of the sinusoidal inverter lies in the switching control, where the waveform and frequency are determined by this controller, one of which is the SPWM wave. In the market, there is an EGS-002 series SPWM generator, this module operates at a fixed frequency of 50 Hz or 60 Hz, so it cannot be used to generate electrical power with a variable frequency. For this reason, this research is carried out, the initial stage is to make an Arduino-based SPWM generator with specifications as close as possible to the EGS-002. The system built consists of Arduino Uno as a SPWM signal generator, IR-2110 driver as a floating voltage provider (bootstrap) for the IRZF44N N-type MOSFET transistor in the H-bridge circuit. The results obtained are the Arduino Uno microcontroller can generate SPWM signals with the results in the form of pure sinusoidal waves with a frequency of 50 Hz.

Penelitan ini merupakan langkah awal penelitian yang berkelanjutan. Hal ini bermula dari banyaknya mahasiswa pada program studi teknik Elektronika baik pada jenjang Diploma-III maupun Diploma-IV yang membuat dan menggunakan inverter dalam tugas akhir/ skripsi mereka. Berdasarkan informasi dan pengamatan yang ada di tengarai mayoritas alat tidak berhasil dan mahasiswa belum memahami baik secara konsep dan desain sistem yang telah di buat. Hal ini disebabkan antara lain karena kurangnya sarana praktikum di bidang elektronika daya khususnya yang berkaitan tentang inverter. Di pihak lain, sistem inverter sangat dibutuhkan sekali dalam sistem elektronika, mulai dari sistem catu daya AC portable, sistem catu daya emergency, sistem catu daya pada energy terbarukan (sistem sel-surya, sistem angin dan lain-lain) serta pada sistem kendali industri.Pada penelitian ini digunakan 4 buah inverter yang dibeli di pasar baik secara langsung maupun secara on-line. Hasil yang didapat ada dua jenis inverter yang ada di pasaran, yaitu pertama : gelombang luaran berbentuk sinusoida yang dimodifikasi (modified sinusoida) dan kedua : gelombang luaran berbentuk sinusoida murni. Kedua jenis ini pada rating daya yang relatif sama mempunyai selisih harga yang signifikan.Tegangan luaran tidak tepat 220 volt tergantung merek inverter dengan Tingkat regulasi tegangan antara 1% hingga 7%, dan yang terbaik adalah inverter dengan merek Souer. Stabilitas frekuensi relatif baik mendekati 50 Hz, dengan toleransi maksimum 0,25%. Stabilitas frekuensi terbaik dimiliki inverter Paco dengan frekuensi 50 Hz. This research is the first step of ongoing research. This starts from the number of students in the Electronics Engineering Study Program at both Diploma-III and Diploma-IV levels who make and use inverters in their final project. Based on the information and observations that were found to be the majority of the tools were unsuccessful and the students did not understand both the concept and design of the system that had been made.This is due, among other things, to the lack of practical facilities in the field of power electronics, especially those relating to inverters. On the other hand, inverter systems are very much needed in electronic systems, ranging from portable AC power supply systems, emergency power supply systems, power supply systems to renewable energy (solar cell systems, wind systems, etc.) and to industrial control systems .In this study 4 inverters were purchased in the market either directly or online. The results obtained there are two types of inverters on the market, namely first: output waves in the form of modified sinusoidal (modified sinusoid) and second: external waves in the form of pure sinusoids. Both of these types at relatively similar power ratings have a significant price difference.Output voltage is not exactly 220 volts depending on inverter brands with voltage regulation levels between 1% to 7%, and the best is the inverter with the Souer brand.Relatively good frequency stability approaches 50 Hz, with a maximum tolerance of 0.25%. The best frequency stability is owned by a Pacoinverter with a frequency of 50 Hz.

Duwet Village have potential that cannot be underestimated. Duwet Village has a UMK that can produce several superior products, including corn rice (gerit), cassava crackers and bamboo crafts (besek). They need media that can be used for marketing media. However, the lack of promotion of the mainstay products produced by Duwet Village can affect the sustainability Therefore, we need a promotional media for superior products in Duwet village that can improve the quality of as well as support efforts to increase consumers of the mainstay products in Duwet village. Given the beauty of a promotional media but also a very effective promotional media and can bring many benefits to a business. With this problem, we propose the manufacture of displays of superior products from Duwet village. This display will be used as a special place to place corn rice, cassava crackers and bamboo crafts which are the mainstay of Duwet village. This display is very useful as a medium for promoting flagship products to all visitors who come to Duwet village which incidentally will become one of the local tourist destinations in Malang Regency.
