Abstract

Sargassum sp merupakan jenis rumput laut yang tumbuh subur secara alami di perairan Indonesia, termasuk di Perairan Simeulue, Provinsi Aceh. Sargassum sp. mengandung berbagai senyawa bioaktif yaitu fenol yang berpotensi sebagai antioksidan. Sargassum sp. di Perairan Simeulue belum dimanfaatkan oleh masyarakat setempat dan belum ada laporan ilmiah tentang total fenol dan aktivitas antioksidan dari rumput laut tersebut. Tujuan penelitian ini menentukan aktivitas antioksidan dan total fenol Sargassum sp yang terdapat di Perairan Simeulue. Metode penelitian meliputi pengambilan sampel rumput laut, preparasi dan ekstraksi sampel rumput laut, uji fitokimia, analisis total fenol dan analisis aktivitas antioksidan rumput laut. Analisis data menggunakan analisis regresi linear untuk melihat hubungan total fenol dengan aktivitas antioksidan DPPH Sargassum. Hasil penelitian menunjukkan bahwa total fenol dan aktivitas antioksidan lima jenis rumput laut genus Sargassum (S. muticum, S. binderi, S. crassifolium, S. granuliferum, S. fluitans) di Perairan Simeulue menunjukkan nilai yang bervariasi. Total fenol 7,45-9,02 mg GAE/g dengan nilai tertinggi terdapat pada S. binderi dan nilai terendah pada S. fluitans. Aktivitas antioksidan 74,7-152,4 μg/mL dengan nilai tertinggi terdapat pada S. binderi, sedangkan nilai terendah terdapat pada S. fluitans. Hasil analisis korelasi (R2 = 0,9059) menunjukkan bahwa aktivitas antioksidan rumput laut genus Sargassum berhubungan erat dengan total fenol. Kelima spesies rumput laut Sargassum di Perairan Simeulue mempunyai aktivitas antioksidan yang kuat (74,7-152,4 μg/mL) sehingga berpotensi dikembangkan sebagai antioksidan.

Abstract

Danau Laut Tawar di Kabupaten Aceh Tengah, Indonesia, memiliki luas permukaan 5.862 ha, garis pantai 49,75 km, kedalaman maksimum 84,23 m, kedalaman rata-rata 25,19 m, dan daerah tangkapan air seluas 18.877 ha. Danau ini merupakan danau tektonik dan bersifat multiguna seperti berperan sebagai sumber plasma nutfah, air baku air minum dan pertanian, perikanan, dan sumber pembangkit listrik tenaga air. Aktivitas antropogenik akibat pemanfaatan sumber daya di daerah tangkapan air dan perairan meningkatkan pemuatan fosfor ke perairan tersebut. Penelitian ini bertujuan untuk menghitung kapasitas beban fosfor dan dampak kegiatan keramba jaring apung terhadap pencemaran fosfor di Danau Laut Tawar. Data primer dan sekunder dikumpulkan dan dianalisis menggunakan berbagai pendekatan seperti studi literatur, pemodelan, pengukuran in-situ serta ex-situ, dan wawancara. Hasil penelitian menunjukkan konsentrasi fosfor di perairan Danau Laut Tawar sebesar 34,00 mg m-3. Beban fosfor dari daerah tangkapan air sebesar 5,19 mg m-3, dengan alokasi beban fosfor sebesar 0,74 mg m-3. Baku mutu fosfor ditetapkan sebesar 40,00 mg m-3, sehingga daya tampung beban pencemaran fosfor mencapai 1,04 ton tahun-1. Keramba jaring apung pada danau memiliki luas 4,46 ha dan menghasilkan limbah fosfor sebanyak 5,25 ton tahun-1 yang terlarut ke perairan danau. Nilai tersebut lebih tinggi dari daya tampung beban pencemaran fosfor pada danau dan memengaruhi kondisi alaminya serta aktivitas yang dilakukan di sekitar danau. Lake Laut Tawar in Central Aceh, Indonesia, covers an area of 5,862 ha with a coastline length of 49.75 km, a maximum depth of 84.23 m, an average depth of 25.19 m, and a catchment area of 18,877 ha. The lake is a tectonic-formed water body and serves various biological and economic functions such as biodiversity resources, water sources for drinking water and agriculture, fisheries, and hydroelectricity. Anthropogenic pressures from economic activities around and within the lake have increased phosphor loading in the water body. This study aimed to determine the phosphor loading capacity and the contribution of floating net cage operation on phosphor pollution in Lake Laut Tawar. Primary and secondary data were collected and analyzed using various approaches such as documents, modeling, in-situ and ex-situ measurements, and interviews. The results showed that the phosphor concentration in the Lake Laut Tawar waters reached 34.00 mg m-3. The phosphor load from the catchment area was 5.19 mg m-3, with the phosphor load allocation of 0.74 mg m-3. The maximum threshold for phosphor concentration in a lake is set at 40.00 mg m-3, bringing the phosphor pollution load capacity of the lake to 1.04 tons year-1. However, the floating net cages in the lake covered an area of 4.46 ha and produced 5.25 tons year-1 of phosphorus waste which dissolved into the lake waters. This value exceeds the phosphorus load capacity of the lake and subsequently affects the lake's natural state and the ecosystem services it provides.

Abstract

The structure of the plant community significantly influences the equilibrium of the surrounding environment, affecting the trophic interactions within its ecosystem. The investigation of mangrove vegetation in Cut Mamplam village was carried out in September 2021 to determine the condition and structural characteristics of the mangrove ecosystem by multivariate analysis. The mangrove vegetation in Cut Mamplam Village was sampled at three observation stations by establishing a transect parallel to the coast. Subsequently, the community structure was examined and assessed using cluster analysis and nonmetric multidimensional scaling using the PRIMER v7 software. The study findings indicate that the mangrove forest vegetation in Cut Mamplam Village consists of five species from three families. Avicennia alba, A. lanata, Bruguiera gymnorrhiza, Rhizophora mucronata and Sonneratia alba. The highest density of mangrove vegetation was observed in A. alba in all categories: trees (616.67 ind/ha), seedlings (833.33 ind/ha) and saplings (66666.67 ind/ha). Additionally, the highest important value index (IVI) was recorded in A. alba for all categories: trees (232.16%), seedlings (102.40%), and saplings (228.43%). A similarity of mangrove density between species was noted at 60%, resulting in the formation of two distinct groups. Regarding the basal area, the vegetation stands of A. alba and A. lanata exhibited the highest values (280.61 and 266.03 m2/ha, respectively). The similarity of basal area among the observed species was 20%, resulting in the formation of two distinct groups. Additionally, Station II, classified as having mature vegetation, demonstrated a maturity similarity of 80% between observation stations.

Abstract

Wolffia arrhiza has a growth rate and biomass as well as a good nutritional content for the growth of cultivated fish, especially herbivorous fish. Due to the high protein content (up to 45% of the dry weight), Wolffia is an excellent plant for the production of various biologically active substances, especially proteins. These plants can double every 1-6 days, similar to algae or mushrooms, and the number of leaves doubles every 2-3 days. This study aims to determine the effect of different fertilizer sources on doubling time, relative growth rate, population density and biomass of Wolffia arrhiza and water quality. The method used in this research is experimental. The research design used a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The treatments were as follows: treatment A: chicken manure, B: cow manure, C: buffalo manure and D: goat manure with each dose of 200 grams. Parameters observed included doubling time, relative growth rate, population density, biomass and water quality parameters. The results showed that treatment B (cow manure) gave the highest value for doubling time, 1.59 days, relative growth rate 0.392 g/day, population density 209.75 ind/cm2, biomass 94.97.

Abstract

The main problems faced today are first, limited capital in developing a goat fattening business. Such high demand for goats is not accompanied by the provision of additional cages to place ready-made goat seeds to be fattened. Second, the lack of knowledge and understanding of good goat farming. Including the cleanliness and maintenance of the cage and even maintenance. Third, the lack of understanding of digitalization technology in running a goat fattening business. such as, making financial reports, and online marketing through existing applications. The purpose of this activity to partners is to increase the quantity of goat sales with good quality. Increased sales result in increased revenue that partners will get. Business expansion brings good changes in creating job opportunities to help this business. The method used to solve the problem is assistance such as helping to find business capital, as well as providing the latest digitalization trainings starting from the time this activity is carried out until after this activity is carried out on an ongoing basis.
