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.

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 18â°C. 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.

Palm starch waste obtained from the Aci Kawung vermicelli flour factory in Ciamis, Indonesia, poses an environmental problem that also impacts the health of the surrounding community, thus requiring an effective treatment method. Silica synthesis from sago starch waste was performed using a coprecipitation method with 2M HCl. This study aimed to characterize the silica from sago starch waste using X-ray fluorescence (XRF) analysis to determine the elements, scanning electron microscopy (SEM) to determine the morphology, and a particle size analyzer (PSA) to determine the particle size of the silica. Sample preparation involved determining the weight of the raw material, washing the raw material, followed by physical and chemical activation through burning, calcination, mixing, and grinding, as well as chemical activation by washing with 2M HCl. XRF results showed that the main phase of the sample was SiO₂ at 68.90%. The silica itself can be utilized in wastewater adsorption. SEM analysis clearly shows numerous pores distributed evenly, which are beneficial for wastewater treatment; these evenly distributed pores are useful for adsorbing heavy metals such as Pb, Zn, Mn, and Fe. Additionally, PSA results indicate a particle size of 2.46 μm. This study holds potential for the development of bionanoadsorbent raw materials for water treatment.

This study aims to develop a real-time alcohol monitoring instrument for palm sap fermentation using the MiCS-5524 gas sensor integrated with an Arduino Uno. The system consists of the MiCS-5524 sensor, an Arduino Uno microcontroller, and a 16×2 I2C LCD for real-time display. Sensor calibration was performed using ethanol solutions at 10%, 20%, 30%, 40%, 50% and 60% to establish a linear regression model relating sensor resistance to ethanol concentration. Fermentation monitoring was carried out for 72 hours, with measurements taken every 24 hours. Sensor outputs were converted from ADC values into voltage, resistance, and ethanol concentration using the calibration equation. The calibration yielded a strong linear correlation (R² = 0.982). Fermentation tests showed a consistent increase in ethanol concentration, reaching 53.9% after 72 hours. Comparison with a digital alcohol meter produced relative errors ranging from 2.8% to 6.4%, demonstrating good accuracy, low drift, and stable sensor response. Overall, the developed instrument effectively measures ethanol concentration in palm sap fermentation in real time. Its simple configuration, low cost, and reliable performance make it suitable for small-scale palm sap processing, quality control, and laboratory applications. Further improvements, such as environmental compensation and IoT-based monitoring, are recommended to enhance system performance.
