Abstract

The presence of pollutants is a serious threat to health. One of the pollutants in influencing air quality is carbon monoxide gas. Most of the carbon monoxide comes from motor vehicle exhaust emissions. The purpose of this research is to make a vehicle carbon monoxide gas emission measurement tool using the TGS 822 gas sensor. The research method begins with the hardware design using the TGS822 gas sensor as a carbon monoxide gas sensor then processed with an arduino uno microcontroller and data transfer by bluetooth. The results of the reading of pollutant values ​​are then processed with a microcontroller and displayed on a computer screen using a Bluetooth connector so that it can be monitored in real time. Data obtained from the test results are then analyzed using a regression equation by comparing with data from the reading of standard measuring instruments. The results of testing the instrument shows the value of the regression equation y = -0,0641x ± 38.438 with a value of R2 = 0, 9997. These results show a strong correlation between the data from the CO meter with the CO gas emission gauge that has been made.

Abstract

Penelitian ini bertujuan untuk mengevaluasi kesesuaian lahan bekas penambangan tradisional pada Tanaman Kelapa Sawit (Elaeis gueneensis Jacq) di Kecamatan Lingga Bayu, Kabupaten Mandailing Natal. Enam komposit tanah sampel digunakan dalam penelitian ini sebagai bahan baku penelitian. Purposive sampling digunakan untuk memilih sampel di Desa Aek Manyuruk, Desa Simpang Bajole, dan Desa Bandar Limabung. Investigasi ini dilakukan dengan menggunakan analisis laboratorium dan metode kerja lapangan. Tahap ini diawali dengan observasi wilayah sekitar, dilanjutkan dengan penentuan koordinat pengambilan sampel. Analisis laboratorium meliputi: Tanah tekstur, KTK, Ca (dd), Mg (dd), Na (dd), K (dd), dan C-organik. Hasil evaluasi kepatuhan lahan menunjukkan kondisi kesesuaian lahan sesuai (S2) dengan faktor pembatas bahaya erosi bulan kering (wa), KTK (nr), bahaya basa (nr), dan ringan (eh).

Abstract

Sei Siarti Village, Panai Tengah District, Labuhanbatu Regency have problems in the form of limited clean water sources that are suitable for use. There are several potentials including peat water, drilled well water, and Barumun river water that crosses the village. The condition of peat water that does not comply with quality standards for water that is fit for consumption has a brownish color, high acidity, and the organic matter contained in peat water is high enough to cause an odor. The well water has a salty taste (high salt content) so that what has the potential is Barumun river water even though it has a cloudy color. The method used to purify cloudy river water is through the processes of coagulation (deposition), filtration (filtering), absorption (absorption), and adsorption (ion exchange). This water purifier is made using 2 tubes filled with silica sand, MGS, activated carbon, and zeolite sand so that the water produced is clear and fit for consumption and can be utilized by the surrounding community. The results obtained from this water purification are water that does not have a smell, taste, and is clear in color so that it is suitable for use by the surrounding community

Abstract

The Joint Business Group of Pondok Maggot Marelan which is located in the Village of Falls, District of Medan Marelan, Medan City is a business group that carries out the cultivation of Black Soldier Fly (BSF) which has been able to produce maggot larvae of about 60 kg per week. The existence of this group is very helpful for the community and the local government in managing the existing organic waste. The increase in the production of maggot larvae is hampered because the capacity of the maggot house is still too small. In addition, the processing of existing maggot larvae is also still limited, namely as chicken or duck feed. This service aims to assist partners in increasing and managing the production of existing maggot larvae. Making maggot houses and training in making floating fish feed using maggot larvae is also important as an alternative in post-harvest management of maggot larvae. This service output program includes fish feed training services, making BSF maggot houses with temperature and humidity sensors, activity videos, and scientific articles. BSF cultivation counseling and training activities have been carried out well. The conclusion of this activity is an increase in maggot production due to the addition of BSF maggot biopond houses. In addition, partners also gain new knowledge in the form of how to manage BSF maggots into floating fish feed that can be used in freshwater fish farming.

Abstract

Marindal 1 Village is one of the villages located in Patumbak District, Deli Serdang Regency, North Sumatra Province with an area of ​​810 Ha. Administratively, Marindal 1 Village consists of 12 hamlets and has a population of about 37,000 people. A group of people who are members of the wood processing business are engaged in the business of making furniture such as making frames, windows, and doors. The equipment used in cutting and splitting wood is assembled equipment that is prone to work accidents. In addition, the COVID-19 pandemic has also had an impact on decreasing the market share of the wood processing business. Therefore, a solution is needed in the form of an automatic wood-cutting spindle machine to prevent work accidents as well as training and assistance in the digitalization process of wood processing businesses so that they are better known by the community outside Marindal 1 Village in the hope of increasing sales turnover. The method used in this service consists of 2, namely the provision of a spindle moulder machine and the socialization of assistance in making digital marketing to partners. The output of this service is in the form of publications in national journals, YouTube videos, print and electronic media, and IPR from service videos.
