Manajemen limbah oli sangat penting dilakukan oleh bengkel mobil untuk menghindari pencemaran lingkungan. Beberapa limbah termasuk dalam kategori Bahan Berbahaya dan Beracun (B3).Mayoritas bengkel tidak memiliki pengetahuan dan tidak melaksanakan manajemen ini. Kegiatan sosialisasi ini bertujuan untuk memberikan pengetahuan bagi pengusaha bengkel. Kegiatan dilakukan dengan survey awal sebagai bahan penyusunan materi sosialisasi. Materi sosialisasi antara lain meliputi gambaran umum manajemen limbah dan dampak lingkungan. Materi juga memberikan pengenalan separator air oli, alat peniris oli dan wadah corong oli. Kegiatan dilakukan dengan cara sosialisasi langsung kepada pemilik bengkel di tempat kerja. Hasil survey menunjukkan bahwa pemilik bengkel kurang memahami manajemen pengelolaan limbah, khususnya limbah oli. Sosialisasi materi yang disampaikan dapat diterima dengan baik. Pemilik dapat menerapkan aplikasi-aplikasi sederhana karena kebutuhan biaya yang relatif murah.
Dengue Hemorrhagic Fever (DHF) is a disease caused by Dengue virus. The disease is spread rapidly in the territory of Indonesia by Aedes aegypti mosquito as the vector. Using Moringa Aloifera leaf extract as a natural larvacide is an attempt to control the disease. This study aims to determine the effect of Moringa Aloifera leaf extract on the mortality of Aedes aegypti larvae. Moringa Aloifera leaf extract is obtained by maceration. The experimental design was divided into negative control groups containing aquades, positive controls containing abate and sample treatment groups. Phytochemical test and UV-Vis spectroscopic quantitative test to identify active compounds. A total of 20 Aedes aegypti larvae were put into a glass containing a solution of distilled water, abate solution and sample solution. Observations are made every 2 hours for 24 hours. The results showed that Moringa leaf extract solution could kill larvae at LC50 3953.17 ppm and LT50 18.98 hours. The mortality rates of larvae at each concentration were 1000 ppm, 5.25 units / 2 hours; 2000ppm, 5.28 units / 2 hours; 3000ppm, 5.91 units / 2 hours; 4000 ppm, 7.18 units / 2 hours, and 5000 ppm 8.63 units / 2 hours. The results showed that Moringa Aloifera leaf extract can kill Aedes aegypti larvae because they contain alkaloids, tannins and flavonoids.Keywords: larvacide, Moringa, Aedes aegypti larvae
Corn is one of the cereals that has strategic and economic value and has the opportunity to be developed. The attack of the Sitophilus Zeamais Motsch species becomes one of the obstacles in the process of storing corn. This study aims to develop the potential of plant biopesticides from grinting grass to control the warehouse pests of Sitophilus Zeamais Motsch. This research is a laboratory based experimental study. The independent variables in this study were the gram weight of grinting grass extract and the number of Sitophilus Zeamais Motsch pests. The dependent variable in this study was the mortality of Sitophilus Zeamais Motsch. Grinting grass extract is obtained using maceration method. Qualitative and quantitative tests were carried out to test the active compound content of grinting grass. Vegetable biopesticide toxicity tests were carried out using a completely randomized design. The results showed that variations in the weight of grinting grass affect the content of chemical compounds present in the grass. Based on UV-Vis and FTIR spectra, the content of polyphenols, alkaloids, flavonoids, terpenoids, steroids, and saponins contains 20 gr / 100 mL, there are flavonoids as much, 2.38 mg / mL, saponins as 2.04 mg / mL, alkaloids as much as 1.79 mg / mL, polyphenols 3.15 mg / mL, steroids as much as 2.24 mg / mL and terpenoids as much as 3.15 mg / mL. Based on qualitative tests the active compound is evidenced by changes in color and deposition. While based on pest mortality tests, it was found that almost 50 percent of grinting grass extract can kill corn pests within a period of 7 days of observation with an extract concentration of 800 ppm.

Industri perunggasan banyak diminati dikarenakan hanya membutuhkan waktu yang singkat dalam proses panen yaitu 5-6 minggu. Meskipun peternakan ayam broiler merupakan bisnis yang menjanjikan akan tetapi, pemeliharaan dan penempatan lokasi kandang ayam pedaging memegang peranan yang penting dikarenakan masih memiliki beberapa masalah yang belum terselesaikan. Penelitian ini menggunakan metode eksperimen dengan melibatkan beberapa variabel. Pada penelitian ini terdapat 2 variabel, yaitu variabel bebas yaitu adalah suhu, kelembapan dan kuantitas pakan. Variabel terikat pada penelitian ini adalah sistem monitoring dan controlling berbasis IoT menggunakan NODEMCU ESP8266 dan LCD 16x2. Perancangan dilakukan dengan menggunakan sensor-sensor dan aktuator yang disesuaikan parameter pada penelitian. Hasil analisis data dan pembahasan menunjukkan bahwa sistem monitoring dan controlling pada kandang ayam berjalan dengan baik, pengiriman data yang dilakukan oleh NodeMCU Esp8299 dapat disimpan didalam database dan selanjutnya dapat dimonitoring dan dikontrol oleh pengguna. Pembacaan sistem monitor suhu dan kelembaban dari sensor DHT22 dengan hasil cukup akurat pembacaan sensor DHT22 dengan rata-rata selisih pembacaan suhu 0.0065% hingga 0.0140% dari ketiga percobaan.
The purpose of this Community Partnership Program (PKM) activity is to provide knowledge about the importance of maintaining personal hygiene to prevent the spread of Covid-19 which is increasingly widespread among children. Partners in the activities of TPQ Darussalam students. Stages of activity 1) Planning at this stage the activities carried out are, observation, writing proposals, preparation of socialization materials, preparation of making automatic hand sanitizer tools, debriefing materials, 2) Implementation and socialization. The results of this activity are 1) socialization of automatic hand sanitizers can prevent the transmission of Covid -19 and increase public understanding and knowledge, especially students of TPQ Darussalam, Purwoharjo. 2) the availability of automatic hand sanitizer products in the students of TPQ Darussalam, Purwoharjo. Socialization activities for the use of automatic hand sanitizers and socialization to prevent the transmission of Covid-19 need to be carried out regularly.
