Abstract

Perairan Aceh bagian Barat terletak di bagian Timur Samudera Indonesia. Kawasan ini merupakan perairan yang dinamis karena merupakan bagian dari perairan Indonesia yang terletak di antara dua benua dan dua samudera. Konsentrasi klorofil-a bervariasi secara bulanan di perairan ini. Penelitian ini mengamati variasi konsentrasi klorofil-a berdasarkan sirkulasi angin muson. Analisis konsentrasi klorofil-a dapat digunakan untuk membantu perkiraan produktivitas sebuah perairan. Kami menemukan bahwa konsentrasi klorofil-a di Monsun Barat lebih tinggi daripada di Monsun Timur. Sebaliknya, konsentrasi klorofil-a di Monsun Timur lebih rendah dibandingkan di Monsun Barat.

Abstract

Increased carbon dioxide (CO2) in the atmosphere causes ocean acidification. Acidification becomes a threat to seagrass. Nowadays, one of the challenges that must be faced is to predict the long-term impact of acidification on the physiology of seagrass. This research aims to analyze seagrass Cymodocea rotundata leave physiology responses to pH that consists of chlorophyll-a and b content, photosynthesis rate, and growth rate of seagrass leaf. This research was conducted on September – December 2017 in Marine Habitat Laboratory, Department of Marine Science and Technology, Bogor Agricultural University. The method used a completed randomized design with five repetitions. pH treatment used in this research is low pH (7.55), medium pH (7.78), and control (8.20). The setting of pH value was done by adding CO32-. Chlorophyll-a and b contents, photosynthesis rate, and growth rate on C. rotundata leaf are higher on control pH treatment than medium pH (7.78) and low pH (7.55). ANOVA test shows that only chlorophyll-a is significantly different. The difference pH affects the chlorophyll content of a and b, photosynthesis rate, and leaf growth rate. The low pH of seawater has been shown to inhibit the physiological activity of C. rotundata leaves.

Abstract

Indonesian mainland waters have a high diversity of fish species, so they are listed as one of the waters with mega biodiversity in Indonesia. One of the efforts in managing fishery resources in a sustainable manner as mandated in Law No. 31 of 2009 concerning Fisheries, requires data and information about the types and morphology of fish in a waters. The purpose of this study was to determine and identify the type and morphology of fish caught by fishermen from Tapak Paderi Beach, Bengkulu City. The benefit of this research is to provide information about the types and morphology of fish caught by the Tapak Paderi fishermen in Bengkulu City. The technique used in sampling is the method of sample collection used is random sampling, marine fish samples are taken at random directly from the fishermen of Tapak Paderi. Identification is carried out by calculating the total length, standard length, identification begins with observing and noting the morphology of marine fish, including: color, mouth position, body shape, scale type, tail fin shape, type and number of spines on each fin. Based on the results of the research obtained, it was successful to take an inventory of 12 types of marine fish caught by fishermen at Tapak Paderi Beach, Bengkulu City

Abstract

Macrobenthic fauna is often used as a bioindicator of environmental quality. However, information about the environmental characteristics and the existence of macrobenthic fauna in the mangrove reforestation area is still very limited. The study of the profile of the Seribu Island mangrove reforestation area based on the characteristics of the macrobenthic environment and fauna was carried out in March 2014. The aim of this study is to determine the ecological conditions of the waters around the Seribu Island mangrove reforestation area. To find out the relationship between environmental characteristics and macrobenthic fauna with observation stations carried out by statistics on Correspondence Analysis (CA), while the environmental characteristics that determine macrobenthic fauna and their relationships are carried out with Principal Component Analysis (PCA) statistics and simple linear regression. The results of the study show that the concentration of measured environmental characteristics is not very different between stations and does not exceed the quality standard threshold for marine life. Then the macrobenthic fauna found consisted of 6 species with the highest density at Station 3 (05.00 ind/m2) and the lowest at Station 1 (02.00 ind/m2). At Station 1 the pH and temperature concentration is very high, while Station 2 and 3 have high salinity concentrations. Macrobenthic fauna Atilia (Columbella) scripta, Metopograpsus latifrons, Littoraria scabra, Saccostrea cucculata, and Cardisoma carnifex can be associated with mangroves at all stations. In addition, the environmental characteristics that determine the presence of C. carnifex macrobenthic fauna are pH parameters, where the higher the pH concentration, the lower the density of C. carnifex. Then the environmental characteristics that determine the presence of the macrobenthic fauna of S. cucculata, M. latifrons and A. scripta are determined by DO (Dissolved Oxygen) and salinity parameters namely the lower DO (Dissolved Oxygen) concentration and salinity, the higher the density of S. cucculata, M. latifrons and A. scripta.

Abstract

Banyak penelitian yang telah dilakukan untuk menemukan potensi sumber energi alternatif dari bahan-bahan yang dapat diperbarui dan ramah lingkungan akibat dari menipisnya sumber energi fosil. Salah satu upaya dalam meningkatkan kemandirian energi adalah dengan menyiapkan bahan bakar alternatif potensial yang berasal dari mikroalga. Kecamatan Banda Sakti memiliki potensi sumberdaya pesisir dan lautan yang belum banyak dikaji, salah satunya adalah mikroalga. Tujuan penelitian ini untuk mengetahui jenis mikroalga yang berpotensi sebagai bahan baku biodiesel di Kecamatan Banda Sakti Kota Lhokseumawe. Penelitian dilaksanakan pada bulan Oktober – November 2021 di Perairan Laut Kecamatan Banda Sakti, Kota Lhokseumawe dengan menggunakan metode purposive sampling. Ditemukan sebanyak 143 jenis mikroalga dan ditemukan 4 jenis mikroalga yang telah dikembangkan sebagai bahan biodiesel yaitu Cholera sp., Spirulina sp., Nitzschia sp., dan Chaetoceros sp. Jenis mikroalga yang paling melimpah yaitu Raphidonema sp., jenis ini perlu diteliti lebih lanjut untuk melihat potensi sebagai bahan baku biodiesel. Kelimpahan total mikroalga berkisar antara 350,00–561,11 ind/L. Nilai parameter kualitas perairan masih dalam kondisi baik untuk kehidupan mikroalga. Perairan laut Kecamatan Banda Sakti, Kota Lhokseumawe memiliki potensi mikroalga untuk dikembangkan sebagai bahan baku biodiesel.

Abstract

Shellfish (bivalves) are potential biodiversity of waters with an important significant value used by the community as a food source of highly nutritious animal protein. Based on survey results, several coastal areas in North Aceh District have the potential for shellfish. Still, there have not been any scientific reports on this region's proximate composition of bivalves. This study aims to determine the relative arrangement of the dominant bivalves in the North Aceh District based on species differences and environmental characteristics. The results showed varying proximate bivalve proximate compositions of 4 chief types of shellfish in North Aceh waters. Bivalvia water ranged from 6.9-14.2%, ash ranged from 5.87-8.29%, protein ranged from 32.84-35.87%, fat ranged from 3.04-10.83%, and carbohydrate ranged from 38.11-42.71%. The highest protein and fat content were found in the Crassostrea sp1 type clams. In addition, the differences in the environmental characteristics of the shell sampling locations also resulted in different proximate compositions. The PCA test results showed that the critical variablarrangemente composition was ash and fat content. The environmental parameters, which were the key parameters of the relative arrangement of the shells were the substrate and pH.

Abstract

This community service aims to provide education and improve the skills of the residents of Ulee Pulo Village in making good use of vannamei shrimp waste. Service activities were carried out using the community development approach method through training based on theory and practice with lectures and focused discussion (focus group discussions). The results of the service were carried out well, structured, smoothly, and successfully involving the community directly, especially the wives of the aquaculture farmers of Gampong Ulee Pulo. The target achieved is that the participants already have the skills and practice the process of making compost independently. In conclusion, the community is skilled in making compost independently.
