Abstract

This research was conducted to determine the types of gastropods and the structure of the gastropod community in the Mangrove area of Kuala Batee District, Southwest Aceh Regency. The quantitative descriptive method is used to determine research stations using purposive sampling techniques. Gastropod sampling was carried out at three station locations, each station consisting of three sub-stations with a size of 10 x 10 m. In the substations, 15 transects measured 1 x 1 m, namely, two points at the corner of each transect and one point in the middle. The results of the research showed that the gastropods found were 11 species from 4 ordo, ordo Archaeogastropoda consists of Neritina turita, N.semiconica, N.variegate, Neritodryas dubia, and Clithon corona, ordo Ceanogastropoda consists of Faunus ater and Bitium munitum, ordo Mesogastropoda consists of Cerithidea optusa, Stenomelania plicaria, and Thiara scabra, ordo Ellobiida consist of Cassidula angulifera. The structure of the gastropod community in the mangrove area of Kuala Batee District, Southwest Aceh Regency, has a diversity index ranging from 0.65-1.32, including the medium category, uniformity index values ranging from 0.36-0.63 including the medium category, and dominance values ranging from between 0.33-0.63 is included in the medium category. Environmental parameters in the mangrove area show an average temperature value of 28.20C, a salinity value of 5.6 ppt, and a pH value of 8.3

Abstract

The reluctance of the community to dispose of waste at the Final Disposal Site (TPA) becomes an obstacle to effective urban waste management. The accumulation of waste over time can lead to water pollution problems. One waste management method is composting. Compost is a biodegradable substance that can retain moisture while decomposing in the air and under sunlight. The basic principle of composting technology is based on the natural decomposition process of organic materials. To address this issue, Liquid Organic Fertilizer (POC) can be used. POC is a liquid fertilizer made from various organic materials, such as plants and food scraps. Waste and residues in the body will decompose anaerobically (without oxygen) without the help of sunlight. This activity was carried out at the Pohroh City Hall, Meureudu Subdistrict, Pidie Jaya Regency, on June 8, 2023. The program aims to educate the surrounding community that household waste, such as vegetable waste and rice washing water, can be utilized as liquid fertilizer, which plays an important role in tree planting. This community service was conducted at the Pohroh Village Hall, Meureudu Subdistrict, Pidie Jaya Regency. The production of liquid organic fertilizer (POC) from household waste begins with making a sample using simple tools and materials, such as a bucket, sieve, 1.5-liter mineral water bottle, sugar, rice washing water, vegetable/fruit waste water, and EM4. The success of POC production can be seen from the presence of white spots on the surface, a yellow-brown color, and a scent resembling fermented rice, but without a foul odor. Through education on household waste management, it is hoped that it will increase the community's knowledge, understanding, and innovation in managing household waste.

Abstract

Chlorophyll-a has an important role in determining the trophic status and estimation of the fertility level of waters. The aim of this study was to analyze the variability of the concentration of chlorophyll-a on the coast of Southwest Aceh. This study uses remote sensing technology using Aqua MODIS imagery, the image used is an annual Level 3 Standard Mapped Image (SMI) chlorophyll-a image with a period of 7 years from 2015 to 2021 and has a spatial resolution of 4 km. The image is processed using software, namely SeaDAS and ArcMap. The results of this study showed that the distribution of the highest annual chlorophyll-a concentration was in 2019 at 0.29 – 2.27 mg/m3, and the lowest chlorophyll-a concentration was found in 2020 ranging from 0.29 – 1.02 mg/m3. The average concentration of chlorophyll-a in Southwest Aceh waters for 7 years (2015-2021) shows a low chlorophyll-a concentration ranging from 0.29 to 1.22 mg/m3 and belongs to oligotrophic and mesotrophic waters.

Abstract

This study aimed to determine the sediment grain size distribution in four estuary locations in Aceh Jaya (Kuta Tuha, Lhok Geulumpang, Krueng No, Keude Unga). These findings will contribute to our understanding of sediment dynamics in estuarine environments and inform management strategies for these critical coastal habitats. The methods used in this study, such as mean, sorting, skewness, and kurtosis, and determination of sediment textural with ternary plot, were used to determine the sediment grain size distribution. In Addition, it will examine the relationship between sediment grain size composition and spatial distance to mouth bar using the Spearman correlation. Composition sediment at all locations dominated by fine sand. Grain size variations (26.735 198.709 m) show that at all locations mainly consists of very fine sand whereas at Kuta Tuha combination of fine sand and medium sand. The variations of sorting (1.193 2.59), skewness (-0.625 0.876) and kurtosis (0.46 6.883) indicate moderately sorted, very coarse skewed, and very platykurtic sediments. Textural sediment classified as sand, silty sand, and very slightly silty sand. We also found positive correlation between spatial distance from mouth bar and sediment composition. These findings will contribute to our understanding of sediment dynamics in estuarine environments and inform management strategies.Keywords:Sediment grain distributionTextural of sedimentAceh Jaya EstuarySortingSkewness

Abstract

AbstrakGastropoda menjadi salah satu sumberdaya hayati non ikan yang mempunyai keanekaragaman tinggi. Gastropoda juga berperan penting dalam fungsi ekologi dan siklus rantai makanan pada ekosistem mangrove. Mangrove merupakan salah satu sumber makanan gastropoda yang dapat membantu pertumbuhannya sehingga dapat meningkatkan keanekaragaman gastropoda di sekitar kawasan mangrove. Namun, adanya aktivitas penebangan pohon mangrove menjadi lahan pemukiman dan kebun sawit dapat mempengaruhi kondisi lingkungan tempat hidup gastropoda. Penelitian bertujuan mengetahui informasi tentang jenis-jenis gastropoda di kawasan mangrove  Kecamatan Kuala Batee Kabupaten Aceh Barat Daya. Penentuan stasiun penelitian menggunakan teknik purposive sampling. Gastropoda yang ditemukan di kawasan mangrove  Kecamatan Kuala Batee Kabupaten Aceh Barat Daya sebanyak 11 spesies dari 4 ordo yaitu Archaeogastropoda antara lain Neritina turita, Neritina semiconica, Neritina variegate, Neritodryas dubia, dan Clithon corona, dari ordo Ceanogastropoda Faunus ater dan Bitium munitum, dari ordo Mesogastropoda yaitu Cerithidea optusa, Stenomelania plicaria, dan Thiara scabra,  dari ordo Ellobiida yaitu Cassidula angulifera.  Kata kunci : Aceh Barat Daya, Gastropoda, Mangrove
