Abstract

Logam berat adalah unsur logam dengan massa jenis lebih dari 5 g/cm3. karena sifat Logam berat yang sulit untuk didegradasi, sehingga cenderung akan terakumulasi pada lingkungan. Logam berat dapat terakumulasi dalam tubuh organisme dan konsentrasi dapat semakin tinggi, atau dapat mengalami bioakumulasi dan biomagnifikasi dan akan akan mengancam keberlangsungan hidup organisme aquatik. Penelitian ini bertujuan untuk mengetahui kadar logam berat timbal (Pb), besi (Fe), dan zink (Zn) di dalam air sungai Bah Bolon Kota Pematangsiantar. Penelitian ini dilakukan pada bulan Agustus-September 2023. Pengambilan sampel air dilakukan dengan memilih 3 stasiun penelitian dengan 3 kali pengulangan. Kemudian kandungan logam berat sampel dianalisis menggunakan metode Spektrofotometri Serapan Atom (SSA). Hasil penelitian ini menunjukkan bahwa kadar logam berat besi (Fe) lebih tinggi dibandingkan logam berat (Pb) dan ((Zn). Hasil uji  besi (Fe) pada semua stasiun berkisar 0,08-0,51 mg/L, timbal (Pb) sebesar 0,003 mg/L, zink (Zn) berkisar 0,001 mg/L, suhu berkisar 25,06-26,9 oC, pH berkisar 7,18-7,61, DO berkisar 6,33-7,2 mg/L. Kualitas perairan sungai Bah Bolon berdasarkan PPRI No.22 Tahun 2021 untuk parameter timbal (Pb), zink (Zn), besi (stasiun 2 dan 3), pH, DO, dan suhu,  masih memenuhi standar baku mutu kelas 2 dan layak untuk digunakan sebagai sumber air irigasi atau pertanian dan untuk kandungan besi (Fe) di stasiun 1 telah melebihi batas baku mutu dan tidak layak untuk digunakan lagi.

Abstract

Macrozoobenthos is a group of organisms that live in or on the surface of the bottom sediment of waters and have a length of more than 1mm. One of the habitats of macrozoobenthos is the freshwater ecosystem in the Bah Biak River, Pematangsiantar City, North Sumatra Province. It is known that macrozoobenthos can provide food availability for other organisms and as an indication of the suitability of the potential quality of waters, especially pollution indicators and play an important role in the decomposition process of organic matter in sediments in freshwater ecosystems so that the macrozoobenthos community can be used as an indicator of the balance of aquatic ecosystems. This study aims to; To identify the diversity, uniformity and dominance of Macrozoobenthos in the Bah Biak River area, Pematangsiantar City, North Sumatra Province. This study used a combination of two transect methods, namely line transects and quadrat transects. Determination of the research location using purposive sampling techniques. Data analysis using qualitative and quantitative analysis. The results of the study showed that there were 4 species of Macrozoobenthos consisting of 2 classes with a total of 95 individuals. The diversity of Macrozoobenthos in the Bah Biak River, Pematangsiantar City, North Sumatra Province is classified as moderate with a diversity index of H’ = 1.27 – 1.35, the evenness index is classified as stable ranging from 0.92 – 0.97 and the dominance index is classified as high.

Abstract

Layang fish is a type of fast swimmer, pelagic, sedentary and likes to group, lives in waters with high salt content (32-34 ppm) and likes clear waters. Layang fish are mostly caught in waters within 150-200 ml from the coast. Little is known about fish migration, but there is a tendency that during the day schools of fish move to deeper water layers and at night to the upper layers of water (TARIGAN, 2019). Chlorophyll-a is one of the indicator parameters of water fertility level found in phytoplankton. Chlorophyll-a concentration is commonly referred to as the photosynthetic pigment of phytoplankton photosynthesis. In marine waters, the chlorophyll-a index can be associated with fish production or more precisely, it can describe the level of productivity of fishing areas (Safruddin and Zainuddin, 2008).This research was conducted using the survey method, which is to collect existing data in the field by making direct observations by following the fishing process with fishermen for one month, and taking data on the catch of Kite fish at the Department of Marine and Fisheries, Silbolga Nusantara Fishing Port. Chlorophyll-a image data that will be overlaid with fish catches that have been categorized based on the number of catches and fishing units. The success of the fishing process carried out by fishermen depends on the fishing area, if you know the potential fishing area, it will facilitate fishermen in the fishing process. Fluctuations in catches are inseparable from several optimum oceanographic factors in these waters, namely, temperature and chlorophyll-a. Fish will look for the optimum temperature in their body and chlorophyll is useful for the food chain process in a body of water. The results of the regression test show that the concentration of chlorophyll-a has a “Moderately Strong Relationship” but there are also several factors that are not measured in this study that affect the catch of kite fish.

Abstract

This study examines the patterns of water usage from Umbul Panglong in Nagori Pariksabungan, Dolok Pardamean District, Simalungun Regency, North Sumatra Province. Data collection was conducted using a mixed-method approach, combining direct observation and interviews with several household heads representing diverse water users. The research findings classify water usage into three main categories: (1) Domestic needs, including drinking water consumption, cooking, bathing, and washing, which are the community’s top priorities; (2) Agricultural activities, particularly for irrigating rice fields and farms that support local food security; and (3) Productive economic activities such as fish farming, small-scale livestock raising, and home industries that require a clean water supply. Water usage patterns are influenced by factors such as water resource availability, seasonal variations, socioeconomic conditions, and local wisdom in natural resource management. The study reveals the existence of a traditional community-based water management system rooted in mutual cooperation (gotong royong), which has been practiced for generations. However, this system faces challenges due to changing weather patterns and increasing water demand. The existing water distribution system requires improvements to ensure more equitable and sustainable access.
