Abstract

Mesjid Sunnah Alhidayah dan Yayasan Al Mujahidah Sumatera Utara merupakan salah satu rumah ibadah dan sekolah yang terletak di kelurahan Sari Rejo Kecamatan Medan Polonia yang belum mendapatkan pasokan air bersih dari PDAM Tirtanadi. Masjid Sunnah Alhidayah dan sekolah yayasan Al Mujahidah menggunakan sumur bor untuk mendapatkan pasokan air yang digunakan untuk kebutuhan sehari hari. Masalahnya kondisi air yang diperoleh dari sumur bor berwarna kekuningan, keruh, dan berbau. Warna air sumur yang kekuningan, keruh dan berbau ini menjadi tak layak untuk digunakan apalagi untuk dikonsumsi, tetapi tetap saja warga menggunakan air sumur tersebut untuk keperluan ibadah (mandi dan berwudhu) tanpa melalui proses pengolahan atau penyaringan sama sekali. Implementasi ilmu pengetahuan teknologi di Mesjid Sunnah Alhidayah dan Yayasan Al Mujahidah yang akan dilakukan berupa teknologi alat penjernih air yang diintegrasikan dengan pompa air tenaga surya. alat penjernih air yang diintegrasikan dengan pompa air tenaga surya memiliki keunggulan tidak menggunakan bahan kimia karena hanya menggunakan filter berbasis karbon aktif, pasir zeolit, dan pasir manganese greensand, mengontrol air masuk dan air keluar secara otomatis, filter mudah dibersihkan, menggunakan tenaga surya sehingga ramah lingkungan dan menghemat biaya pembayaran listrik PLN. Implementasi ini dilakukan untuk mengatasi masalah yang sedang dihadapi oleh masyarakat di Kelurahan Sari Rejo umumnya dan mesjid Sunnah Alhidayah serta Yayasan Al Mujahidah khususnya dalam proses penjernihan air, sehingga air dari sumur bor menjadi layak untuk digunakan bahkan untuk dikonsumsi.

Abstract

Orange is one of the local fruits, which is a source of income for farmers in Narigunung 1 Village, Tiganderket District, Karo Regency. However, in recent years, many orange orchards have been attacked by the fruit fly pest of Bactrocera sp. (Diptera: Tephritidae), causing the oranges become rotten and fall. This resulted in losses for farmers; there are crop failures in some orchards, while the farmers had to pay off a large pesticide purchase. One of the effective ways to ward off the arrival of these fruit flies is by using ultrasonic waves. Based on a research, fruit flies will be disturbed if there are ultrasonic waves with a frequency of 25-30 KHz that work based on ambient temperatures above 18⁰C. In addition, to control the fruit fly population, this community service also used a modified steiner trap, employing methyl eugenol, which can stimulate male fruit flies to enter the trap. Both repellents and traps will be made at a height of where fruit flies are active around the orange tree. With this control system, the orange orchard will be free from fruit flies so that farmers will no longer experience losses; besides, ecological trapping of fruit flies will reduce the population of fruit flies around Narigunung 1 Village, Karo Regency.
