Abstract

The study of Pb in suspended solid and dissolved in the Belawan Port Waters was conducted on June until November 2021. Analysis of Pb content in suspended solid was mesured at Laboratory of Environmental Health and Disease Control Engineering Center (BTKLPP) in North Sumatra Province. Pb content in suspended solid at high tide ranged from <0,02-0,06 mg/l and at low tide ranged from 0,02-0,065 mg/l. The content of dissolved Pb at high tide ranged from 0,210-0,651 mg/l and at low tide ranged from 0,288-0,750 mg/l. Content of Pb in the waters of Belawan Port has passed quality standard of the Minister of Environment of Republic Indonesia that means the Harbour area is polluted and improper for drinking water as well as for fish cultivation.

Abstract

Pada pengabdian yang dilakukan pada masyarakat petani ikan nila didapatkan angkas sebesar 70 % Masyarakat mengakui sangat puas (baik), 20% Cukup baik, dan 10% Kurang, adapun dikatakan cukup baik karena alat kincir air memiliki energy dari panas matahari yang cukup baik dan memiliki nilai ekonomi yang efisien dalam penggunaan jangka panjang dan penggunaan pelet buatan sendiri dapat meminimalisir biaya pembelian pelet ikan di toko pakan ikan. Kemudian menwab kurang karna diakibatkan biaya awal pembuatan kincir air yang cukup mahal tetapi baik untuk jangka panjang. Hal ini juga dapat terlihat pada data grafik kepuasan Petani ikan terhadap Workshop atau pun penyuluhan pengabdian kepada masyarakat desa silaumalaha

Abstract

Masyarakat simalungun belum memiliki pengetahuan tentang dampak bakteri coliform fecal bagi lingkungan perairan terkhusus bagi biota air karena kualitas air di simalungun terus menerus menurun sehingga pengabdian ini bertujuan untuk memberikan penyuluhan tentang dampak bakteri coliform fecal bagi biota air. Pengabdian ini telah dilakukan pada bulan September-Oktober 2022 di simalungun dengan metode penyuluhan dan angket yang diikuti oleh peserta sebanyak 20 orang. Hasil penyuluhan menunjukan bahwa masyarakat paham 100%  tentang dampak bakteri coliform fecal yang dapat membunuh biota air yang lain karena terjadi kompetisi memperebutkan oksigen dan jika terus menerus terjadi maka akan merusak lingkungan dan ekosistem perairan. Dari penyuluhan ini terlihat animo masyarakat sangat tinggi, dan mereka menjadi lebih paham tentang upaya memperbaiki kualitas air dengan mengurangi pembuangan limbah organik ke perairan di simalungun.Simalungun people have yet to learn the impact of faecal coliform bacteria on the aquatic environment, especially for water biota because the water quality in Simalungun continues to decline, so this service aims to provide education about the impact of faecal coliform bacteria on water. This service was carried out in September-October 2022 in Simalungun with the counselling and questionnaire methods that 20 participants attended. The counselling results show that the community understands 100% about the impact of faecal coliform bacteria, which can kill other aquatic biota due to competition for oxygen. If this continues, it will damage the environment and aquatic ecosystems. From this counselling, the community's enthusiasm is very high. They have become more aware of efforts to improve water quality by reducing the discharge of organic waste into waters in Simalungun.

Abstract

Aquatic plants are float on the surface of the water and easy to continue to grow and can even be detrimental to the environment and other aquatic organisms it they have expanded, so it is necessary to use them to reduce losses. One way to use aquatic plants is to know the phytochemical compounds of these aquatic plants, so that they can be used as medicinal plants. The purpose of this study was to determine the phytochemical compounds found in aquatic plants such as water eceng gondok (Eichhornia crassipes), genjer (Limnocharis flava) dan kiambang (Salvinia molesta). This research was conducted at the water resources management laboratory University of HKBP Nommensen Pematangsiantar with the extraction method from the leaves. Phytochemical test carried out consisted of alkaloids, flavonoids, saponins, phenolics, tannins, and vitamin c. phytochemical test results of alkaloids, flavonoids, phenolics and vitamin c were found in the three types of leaves the aquatic plants, while saponins were not found in genjer and eceng gondok, then tannins were not found in genjer. The highest phytochemical content is found in kiambang, and the lowest phtochemical content is found in genjer plants. Furthermore, it is necessary to test the antibacterial activity of aquatic plants originating from the water of Pematangsiantar city.

Abstract

Based on geological conditions, Indonesia is located between the Indo-Australian plate, the Eurasian plate, and the Pacific plate, making Indonesia prone to tectonic earthquakes. However, since the big earthquake that occurred in Aceh on December 26, 2004, the geological conditions in Sumatra have undergone significant changes marked by stressful situations in the western to southern regions of Sumatra, especially on Sibayak Volcano. This study used data from BMKG and Global CMT, which included magnitude (Mw), depth, earthquake coordinates (longitude and latitude), type of earthquake, strike, dip, and rake. From the analysis using Coulomb 3.3, the highest coulomb stress value of Sibayak Volcano was obtained in 2015 with an average change in coulomb stress of 0.235 bar, shear 0.1909 bar, normal 0.1106 bar. However, the lowest coulomb stress value occurs in 2021 with a moderate shift in coulomb stress of 0.0593 bar, shear 0.0251, normal 0.0849 bar.

Abstract

Batak fish (Neolissochilus sumatranus) is an endemic fish to North Sumatra Province, especially in Lake Toba. Currently, Batak fish are categorized as endangered due to overfishing and their habitat is starting to be damaged, so conservation efforts need to be made, one of which is from microbiological analysis of water found in the aquatic environment in Batak fish farming. This study aims to determine the quality of water in Batak fish farming in terms of aquatic microbiology. This descriptive research was conducted in Lake Toba waters, using random purposive sampling at 4 stations, namely: Parapat, Ajibata, Gorat, and Haranggaol Lake Toba, North Sumatra Province. Microbiological analysis was carried out at the Water Resources Management Laboratory, Faculty of Mathematics and Natural Sciences, University of HKBP Nommensen Pematangsiantar. The results showed that the bacteria found in Batak fish farming in Lake Toba waters were fecal coliform bacteria with numbers at station 1 (360/100 ml), station 2 (830/100 ml), station 3 (1310/100 ml), and station 4 (1110/100 ml). In general, the quality of Batak fish aquaculture water does not meet water quality standards, because the content of fecal coliform bacteria is above the 1000/100 ml quality standard.

Abstract

Research on SST and chlorophyll-a content using GEE Cloud technology in Sibolga Waters has been carried out since February-December 2019. The analysis was carried out using the MODIS AQUA-L3SMI satellite. The SST results showed that it spread evenly from the coast of Sibolga to the sea, which was 28-33 0C and did not fluctuate, while the content of chlorophyll-a spread evenly, from February-April with a value of 0,1-1 mg/m3 varied, namely from June-August, and fluctuations namely in October-December 2019 with an amount of 0,5-2 mg/m3. SST spreads evenly, varies, and fluctuates around the outskirts of Sibolga coastal waters to the middle of Sibolga Waters, which is unsuitable for demersal fish species. Meanwhile, the chlorophyll-a content spreads evenly, varies, and fluctuates. The high content of chlorophyll-a in all waters and the high SST will make a certain type of fish that can live, namely carnivorous fish species. Image data can be used to map SST distribution patterns and chlorophyll-a content in Sibolga Waters.

Abstract

Community service was carried out on 27-28 October 2022 at SMP Negeri 3 Jorlang Hataran. The activity was carried out by introducing about protecting and caring for mangroves in Belawan waters to serve as ecotourism. The results obtained were that there were 10 types of mangroves located at 3 stations, namely Sonerattia alba, Avecennia offinalis, Avicennia alba, Bruguiera sexangula, Bruguiera cylindrica, Bruguiera gymnorrhiza, Rhizophora mucronata, Rhizophora apiculata, Rhizophora stylosa and Ceriops tagal. The highest mangrove species were Bruguiera cylindrica and Rhizophora stylosa and the lowest were Sonerattia alba, Avecennia officinalis, Bruguiera sexangula, Rhizophora mucronata, Rhizopora apiculate, and Ceriops tagal.
