Abstract

Pandaratan Beach is a Beach located in Pondok Batu area, Sarudik Subdistrict, Tapanuli Tengah Regency which is an area that has seagrass beds with various roles in aquatic biota such as bivalves, where seagrass beds function as nurseries, as a place to search feeding ground, and areas to seek protection. The purpose of this study was to determine the bivalve diversity of seagrass beds at Padaratan Beach, carried out in March to April 2018 using purposive sampling method by taking and observing seagrass vegetation based on utilization. Data analysis included seagrass vegetation analysis, bivalve analysis, and water quality analysis. Found 2 types of seagrass with density at Station I 33.81%, Station II 20.27%, and Station III 25.38%. In bivalves 15 species were found at the study site. Bivalve Diversity Index at Station I 2.45, at Station II 2.48, and at Station III 2.43. Bivalvia uniformity index at Station I 0.91, at Station II 0.91, and at Station III 0.90. The bivalve dominance index at Station I was 0.07, at Station II 0.07, and at Station III 0.05. The relationship between seagrass density and density with bivalve diversity has a strong relationship, and shows that any increase in seagrass density affects the addition of bivalve species.Kata kunci: Bivalvia, lamun, keanekaragaman, pantai pandaratan.

Abstract

Untuk memenuhi kebutuhan energi listrik di Pulau Bali yang semakin meningkat sekitar 6 – 9 % dalam 5 tahun mendatang, pemerintah telah mengupayakan pembangunan PLTU Celukan Bawang. Proyek PLTU Celukan Bawang yang dikerjakan sejak 2013 ini telah beroperasi penuh pada bulan Agustus 2015 sebagai outlet untuk penyaluran transmisi Saluran Udara Tegangan Tinggi (SUTT) 150kV. Terkait masalah isu sosial dengan penolakan warga Desa Celukan bawang terhadap pembangunan yang melintasi rumah mereka dari SUTT, maka pihak PT.PLN (PERSERO) diminta untuk melakukan strategi untuk pengamanan penyaluran agar Sistem Bali aman saat re-route jalur SUTT. Dari hasil simulasi dengan menggunakan Tools PSSE, aliran daya listrik Bali disimulasikan dalam 3 skenario. Skenario 1 melepaskan 1 Sirkit Celukan Bawang – Kapal dan mengoperasikan Pembangkit sesuai dengan merit order, skenario 2 melepaskan 1 sirkit Celukan Bawang – Kapal dan mengoptimalkan Pembangkit di Jalur Selatan, dan skenario 3 dilakukan dengan melepas kedua sirkit Celukan Bawang – Kapal dan mengoperasikan pembangkit di jalur Selatan. Berdasarkan hasil analisis dari skenario berikut di peroleh skenario 1 memiliki kajian lebih ekonomis, andal dan bermutu dibandingkan skenario lainnya.

Abstract

This research was conducted on July - August, 2020 in mangrove ecotourism area ofKampung Kayu Ara Permai, Siak Regency. The purpose of this study was to obtain thevalue of density, frequency, mangrove important value index (INP Mangrove),dominance index value and mangrove diversity index in the mangrove ecotourism areaof Kampung Kayu Ara Permai. Five serial plots with provisions of 10x10 meters2 for 2trees, 5x5 meters for shrubs, and 2x2 meters2 for seedlings. Each plot identified species, measured stem diameter, and the number of individual mangroves. Vegetation analysisusing Mueller and Dumbois formulas to get the value of diversity, frequency, dominanceand importance of plants. The results showed that nine species of mangrove vegetationwere found: Avicennia alba, Avicennia marina, Bruguiera gymnoriza, Bruguierasexangula, Bruguiera sylindrica, Lumnitzera littorea, Rhizophora apiculata, Rhizophoramucronata, and Rhizophora stylosa. The highest importance index was found inRhizophora apiculata (102.4%). Mangrove diversity in this area is high (5.28) and isdominated by Rhizophora apiculata. The high diversity of mangroves is due to thepreservation of this area by community groups.

Abstract

ABSTRACTAlong the watershed of the Siak River, many anthropogenic activities produce pollutant that enter the water and thus decrease the quallity of the water in that river. To understand the water quality of the river based on plankton community, a study has been conducted in December 2019. Samplings were conducted 3 times, in 3 sampling points, once/ week. The plankton were then identified and counted. Results shown that there were 40 species on phytoplankton presence, they were consisted of 6 classes, namely Bacillariophyceae (11 species), Clorophyceae (19 species), Cyanophyceae          (7 species), Dinophyceae (1 species), euglenophyceae (1 species) and chrysophyceae (1species). The zooplankton presence was 5 species (3 classes) and they were consisted Rotifers (2 species), Cepepoda (2species) and Branchiopoda (1 species). Water quality parameter values were as follow: temperature 27-30 0C, transparency 24-32 cm, pH 5, current speed 0.33-0.43 m/s, DO 4.36-5.12 mg/L, CO2 10.64-13.98 mg/L, nitrat 0.22-0.42 mg/L, phosphate 0.18-0.20 mg/L. The number of the plankton presence indicates that water in the upstream of the Siak River can be categorized as oligotrophic. Keywords: Phytoplankton, zooplankton, plankton population,  oligotrophic water         quality

Abstract

ABSTRACTMangrove forests in the Sungai Rawa Village has been degraded due to anthropogenic activities. Decrement in mangrove ecosystem will negatively affects the aquatic organims in general, including the gastropods present in that area. To understand the community structure of gastropods in that mangrove ecosystem, a research was conducted on March 2018. There were 3 line transects and in each line there were 5 plots (1mx1m). The gastropods in the plots were collocted manually for 3 weeks. Result shown that there were 11 gastropods species present, they were Cassidula aurifelis, Cerithidea cingulata,      Cerithidea obtusa, Chicoreus capucinus, Ellobium aurisjudae,                        Ellobium aurismidae, Littoraria melanostoma, Littoraria scabra, Nerita balteata, Neritina carnucopia and Telescopium telescopium. The gastropods density was ranged from 9 - 15 organisms/m2. The value of species richness index (Da) was 4.16 - 4.21, the diversity index (H’) was 2.99 - 3.13, the dominance index (C) was 0.12 - 0.14 and the uniformity index (E) was 0.90 - 0.93. The water quality parameters were as follows: temperature was 27 - 29ºC; pH was 7.3 - 7.7 and salinity was 26 - 27.3º/oo. Gastropods community structure in the mangrove ecosystem of the Sungai Rawa Village was good and there was no dominant species.  Keywords: Diversity Index, Mollusca Community, Gastropods Population, Mangrove Forests

Abstract

Every oil and gas processing activity will not be separated from the problem of Ammonia provision, there are still many difficulties. One of the problems that is currently emerging is the problem of the wastewater treatment process. one of the efforts to reduce ammoniacontent in oil processing industry waste is by electrocoagulation process. The aim of the study was to determine the ability of the electrocoagulation method to decrease Ammonia levels and determine the effect of strong current changes and changes in time to decreaseAmmonia. The electrode used is aluminum. Variations in current strength used are 2, 3, 4, 5 Ampere and reaction times of 20, 40, 60 and 80 minutes. The experimental resultsshowed that the best electrical current for ammonia removal was 5 amperes. The best reaction time in the ammonia removal process in this study was 80 minutes of reactiontime. Highest ammonia removal obtained in this study was 79.7% (initial ammonia 52.3 mg / L to 10.6 mg / L).Keywords : electrocoagulation, aluminum, petroleum processing waste, ammonia.
