The waters of Pasir<br />Mayang Beach are influenced by inputs from rivers and the<br />activities of coastal communities, which in turn affect the water<br />quality and aquatic organisms. The purpose of this study was to<br />determine the condition of water quality using seawater quality<br />standards and map them spatially. Water quality parameters<br />surveyed included temperature, salinity, pH, oxygen level and<br />brightness which were measured at 17 survey locations. The<br />survey method used was direct data measurement and the data<br />was grouped into tabular form using Ms. Excel 2010 and the<br />results were compared and matched with seawater quality<br />standards stipulated by the Minister of Environment Regulation<br />No. 51 of 2004. Spatial distribution was carried out using ArcGIS<br />10.4 software and interpolated using the inverse distance<br />weighting (IDW) method. Measurement and analysis results were<br />obtained for temperature parameters between 30-31.6 °C.<br />Salinity 11.3 to 21.7 ‰. pH 7.0-7.9;DO 2.1-3.6mg/L. Based on<br />the research results, the following conclusions can be drawn:<br />Some of the seawater quality of Pasir Mayang Beach still meets<br />the established quality standards, including temperature and pH,<br />so that it can be further classified according to its function.<br />However, there are several parameters that do not meet quality<br />standards, namely: Salinity, DO and Clarity.

This study aims to determine the growth pattern of red snapper landed by fishermen at PPI Lhok Bengkuang. In order to know the growth pattern of L. timoriensis through the long-weight relationship of the fish from the growth aspect of the fish's weight and length. The research was conducted in October–November 2022 at PPI Lhok Bengkuang, South Aceh District. The research method was proportional random sampling and then the data were analyzed using linear regression. The number of individual samples whose growth patterns were analyzed was 30 individuals with the type of species L. timoriensis. Total body length ranges from 22.4 cm-30.3 cm and body weight ranges from 161 grams-455 grams. The results of the regression analysis on L. timoriensis individuals obtained a regression value (b) of 0.0989391 with a coefficient of determination (R<sup>2</sup>) of 0.7180290 which indicates that the weight gain is 72%. The value of b = 0.0989391 means that it is smaller than the normal b value, it is called a negative allometric growth pattern, that is, the length relationship is faster than the weight of the fish. On the growth pattern of L. timoriensis, it is necessary to carry out further research with a longer time and a larger number of samples to obtain more complete data and information.</em></p>2023-10-02T07:41:34SE Asia Daylight TimeCopyright (c) 2023 Nyak Ilahttp://jurnal.utu.ac.id/JLIK/article/view/8095Pengaruh Pemberian Pupuk NPK terhadap Pertumbuhan Bibit Mangrove pada Media Tanam Hydraquent di Yayasan Mangrove Institute Aceh Jaya2024-01-19T14:28:59SE Asia Standard TimePuja Kasmilapujakasmilaputri@icloud.comAsri Mursawalasrimursawal@utu.ac.id<p>The destruction of mangrove forests reduces forest area and mangrove plant species. Mangrove forest restoration requires seeds with good growth and are resistant to pests and diseases. The purpose of this study was to determine the effect of NPK fertilizer application on mangrove seedlings growth in the Hydraquent Garden media at the Aceh Jaya Mangrove Institute Foundation. The research was conducted on September 2022. The tools and materials used in this research were <em>R. apiculata</em> mangrove seeds, soil hydraquent, meter, tools, cutter, wood stake, refractometer, and thermometer. This research used a descriptive method in which it only took the average value of mangrove seedlings growth. There were four types of observations given to mangrove seedlings, namely T0 (no fertilizer), T1 (giving 3 gr of fertilizer), T2 (6 gr), T3 (9 gr) and T4 (12 gr). Based on observations, NPK fertilizer on Hydraquent soil was proven to increase plant height and number of leaves.</p>2023-11-17T03:09:27SE Asia Standard TimeCopyright (c) 2023 puja kasmila m.idrishttp://jurnal.utu.ac.id/JLIK/article/view/8180Pemetaan Kerapatan Mangrove Berbasis NDVI (Normalized Difference Vegetation Index) Menggunakan Citra PlanetScope Pada Sebagian Wilayah Konsesi PT.

The waters around Merak Kecil Island are known for offering a beach and sea atmosphere. In addition, visitors can enjoy a number of facilities such as boat tours, fishing, snorkeling, and enjoying the sights of ships passing by. Related to this, it will have the potential to affect the environmental conditions of Merak Kecil Island, especially the fertility of the waters. The fertility of a waters is influenced by nutrients (nitrate, nitrite, phosphate). Nitrate, nitrite and phosphate act as limiting factors for the growth of organisms and water fertility. This study aims to determine the differences in content and the relationship between nitrate, nitrite and phosphate content and compared with Government Regulation no. 22 of 2021 and ANZECC & ARMCANZ (2000). The research method uses a descriptive method with a quantitative approach while the selection of sampling locations uses a purposive sampling method. Required environmental parameters were taken in situ and air samples were analyzed at the Fish and Environmental Health Testing Center (BPKIL) Serang, Banten. The results showed that there were less significant differences in the content of nitrate, nitrite, and phosphate. The nitrate content exceeded the quality standard, but nitrite and phosphate were not detected.</p>2023-12-06T03:30:14SE Asia Standard TimeCopyright (c) 2023 Dewi Firda Salsabilla, Agung Setyo Sasongko, Ferry Dwi Cahyadihttp://jurnal.utu.ac.id/JLIK/article/view/7655Molecular Identification of Wedgefishes Stingrays (Rynchobatus sp.) at PPI Rigaih, Aceh Jaya Regency by using COI Gene2024-01-19T14:28:59SE Asia Standard TimeWaldi Aminwaldiwaldiamin@gmail.comSamsul Bahrisamsulbahri@utu.ac.idDanie Al Malikwaldiwaldiamin@gmail.comNi Luh Astria Yusmalindawaldiwaldiamin@gmail.comEnex Yuniarti Ningsihwaldiwaldiamin@gmail.comNi Putu Dian Pertiwidian.pertiwi@undiksha.ac.idAndrianus Sembiringandsembiring@gmail.com2023-12-06T03:28:48SE Asia Standard TimeCopyright (c) 2023 Waldi Amin, Samsul Bahrihttp://jurnal.utu.ac.id/JLIK/article/view/8647Evaluasi Dua Metode Pengukuran Pertumbuhan Karang Bercabang Pocillopora verrucosa2024-01-19T14:28:59SE Asia Standard TimeMunandar Munandarmunandar@utu.ac.idFitria Rahmayantifitriarahmayanti@utu.ac.idRudi Hermirudihermi@utu.ac.idHeriansyah Heriansyahheriansyah@utu.ac.idSyahrul Ramadhanramadhanihamfata1422@gmail.com<p>Karang bercabang<em> Pocillopora verrucosa</em> merupakan salah satu organisme karang yang memiliki peran penting dalam ekosistem terumbu karang.

One of them is the substrate as a place for the abalone to attach. The purpose of this study was to determine the effect of different substrates on the growth and survival of abalone (<em>Haliotis squamata</em>). This study used an experimental method using a completely randomized design (CRD) with 4 treatments and 3 repetitions. The treantmen used is the difference in substrate, namely roof tiles, pipes, zinc plastic and bamboo. The results showed that the average absolute length growth was 0,20-0,77 mm, the absolute weight ranged from 0,82-1,06 g and the survival rate was 43,66-77,00%.

Excessive use of mengroves poses a threat to the growth of mengroves, one of which is the conversion of land, therefore it is necessary to make efforts to improve the mengrove ecosystem by planting mangroves. However, in the planting process, it is necessary to match the planting location, including the condition of the substrate. The aim of the research was to determine the percentage of substrate on the growth of Rhizophora sp. mangrove saplings. This research was conducted in June to October 2022 at Kuala Samboja beach, East Kalimantan. The research method is a survey method with a quantitative approach, measuring the success rate of mangrove life and analyzing substrate types. Based on the life success rate, the most mangrove saplings live at SR stations at 28 ind, ST stations at 20 ind and the least success at SD stations at 6 ind. Based on the research location, at SR and SK stations the silt type is dominated by 51-54%, at SL and ST stations the substrate type is dominated by silt (46-49%) and fine sand (39-49%) and at the SD station the substrate type is dominated by sand.
