Abstract

Aceh waters are a place for fishermen to look for fish, one of which was flying fish (Decapratus sp.) which was landed at the Lampulo Ocean Fisheries Port (PPS), North Aceh. Flying fish (Decapratus sp.) was a fishery commodity that was in great demand by people globally, especially in Indonesia. This research aims to measure the length and weight of flying fish (Decapratus sp.) using survey and analysis methods. The results of this research obtained a value for the total number of fish which was 50 fish. With the overall sample length of fish ranging from 140 mm to 205 mm, the dominant total length of fish caught was in the average range of 166.28 mm. Meanwhile, the weight of flying fish (Decapterus sp.) ranges from 31 to 76 grams, with an average fish weight of 46.06 grams. The calculation result of the b value obtained from testing the flying fish (Decapterus sp.) at the Pematangsiantar Parbesaran Market was 2.68, with the r2 value being 0.89. Based on the b value obtained, it can be stated that the length and weight of the fish was < 3, which means negative allometric meaning that length growth is faster than weight growth.

Abstract

Permukaan bumi secara alami tidak hanya menampung air tetapi air dialirkan dari hulu menuju hilir dan ke muara. Kualitas dan kuantitas perairan selalu dipengaruhi oleh aktivitas makhluk hidup. Kebutuhan air tidak hanya tergantung pada kuantitas, namun tergantung juga pada kualitasnya. Tujuan penelitian ini adalah untuk menentukan status mutu perairan sungai asahan. Penentuan kualitas air menggunakan 3 Parameter yakni Fisika, Kimia, Biologi. Parameter fisika yang diukur adalah suhu, Total Dissolved Solid (TDS) atau Padatan yang terlarut. Parameter kimia yang diukur adalah pH, Dissolved Oxigen (DO) atau Oksigen Terlarut, BOD, COD dan Nitrat dan parameter biologi yang diukur adalah Total Coliform. Metode yang digunakan pada penelitian ini yaitu metode deskriptif dengan pendekatan kualitatif. Hasil parameter tersebut akan dibandingkan dengan status mutu air menurut Peraturan Pemerintah No 22 Tahun 2021. Hasil penelitian yang telah dilakukan di Sungai Asahan dapat di simpulkan bahwa, parameter yang memenuhi syarat baku mutu sesuai PP RI No. 22 Tahun 2021 yaitu, Suhu, pH, TDS, COD, DO dan Total Coliform. Parameter yang tidak memenuhi baku mutu air yaitu BOD, dan Nitrat.

Abstract

Muara Panton is an estuary located in Bagan Asahan Village, Tanjung Balai District, Asahan Regency. These waters are known as one of the largest fish producers in North Sumatra Province. Apart from that, it is also used as a ship crossing. The impact of these activities is that heavy metals enter and settle at the bottom of the waters and have a residence time, resulting in contamination by shellfish that will be consumed. This research aims to determine the content of heavy metals lead, copper, chromium and zinc in the feather clam (Anadara atiquanta) in Muara Panton, Bagan Asahan Village, Tanjung Balai District. The implementation is by collecting samples of feather clams (Anadara antiquata) to be tested for heavy metals in the shells to find out the levels of heavy metals found in feather clams in the Panton estuary which will be carried out from July to September 2023. Measurement of the concentration of heavy metals T Lead, Chromium using the Absorption Spectrophotometer (SSA) method. The results of the heavy metal content found in Muara Panton, Tanjung Balai District show that the average heavy metal content of lead is <0.07, chromium with an average of <0.005 mg/kg at all stations with safe limits for consumption of heavy metals lead and chromium in Muara Panton, Bagan Asahan Village, Tanjung Balai subdistrict refers to the PTWI (Provision Tolerable Weekly Intake) value issued by JECFA in FAO/WHO (2004).

Abstract

Mangrove ecosystems are forests that grow in tidal areas, especially on protected beaches and river estuaries that are flooded at high tide and free from puddles at low tide and whose plant communities are tolerant of heavy metals. Heavy metals concentrations in marine sediments have been widely used to assess longterm anthropogenic inputs into the marine environment. Mangrove ecosystems have the ability to store heavy metals such us iron, manganese, Cr, Cu, Co, Ni, Pb, Zinc and Cd, which is known as biosorption. This type of mangrove (Rhizopora Apiculata) is one of several mangrove species that can absorb heavy metals. They do this througha dilution process, which dilutes the concentration of heavy metals in their body tissues, which reduces the metal’s toxicity. The aim of this research is to determine the levels of heavy metals in Rhizopora Apiculata mangrove roots based on the parameters copper (Cu), Lead (Pb), Chromium (Cr), Cadmium (Cd) and zink in Bagan Asahan Baru Village, Tanjung Balai. The results of the analysis of test data for the levels of heavy metals Copper, Lead, Chromium, Cadmium and Zink that were obtained were then compared with the water quality standarts that have been determine in Appendix IV PPRI Number 22 of 2021 concerning water quality standarts and the like. The results of heavy metal measurements on copper (Cu), Lead (Pb), Chromium (Cr), Cadmium (Cd) and Zink carried out in the Baristand Medan Laboratory, it can be concluded that the heavy metal concent in the roots of Rhizopora Apiculata Mangroves in the waters of Bagan Asahan Village Baru does not meet the quality standarts of PPRI No. 22 of 2021 class IV.

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

Writing textbooks is a skill that teachers should have to improve their professionalism. Teacher textbooks can be published and marketed in various formats. However, not many teachers are interested in writing textbooks. Several factors that hinder teacher motivation in writing textbooks include teachers' lack of understanding of book writing techniques, lack of ideas, and lack of free time. To overcome this, training in textbook preparation techniques is needed. This training and writing assistance will be provided by people who have experience making textbooks. The textbook writing training program consists of several activities, including socialization about textbook creation, training in textbook creation, mentoring in textbook creation and evaluation of the results of the training and mentoring. The aim of this PKM is to provide insight and skills in writing textbooks through training and assistance in writing textbooks for teachers or teaching staff at PATMOS learning homes. Apart from that, the results of this training produce textbook products that will be used in the PATMOS Learning home learning process with the hope of increasing children's reading literacy.
