Abstract

Plankton adalah organisme hidup kecil yang mengapung di kolom air dan merupakan komponen ekosistem perairan yang sangat penting. Penelitian ini bertujuan untuk mengetahui parameter fisika-kimia perairan, komposisi plankton dan korelasi antara keanekaragaman plankton dengan parameter fisika-kimia perairan dengan menggunakan analisis statistik. Penelitian ini dilakukan pada bulan Juni 2022 di estuari Sungai Selan, Kabupaten Bangka Tengah. Penelitian dilakukan pada pagi hari. Pengambilan data plankton dilakukan dengan metode tarikan vertikal menggunakan jaring plankton. Sampel plankton yang dihasilkan diidentifikasi di bawah mikroskop dengan tiga ulangan untuk setiap sampel di setiap titik pengamatan. Hasil penelitian menunjukkan bahwa terdapat 24 jenis plankton yang ditemukan di estuary Sungai Selan. Kelimpahan plankton tertinggi terdapat pada titik 4 dengan 701,38 ind/L dan terendah pada titik 1 dengan 197,91 ind/L. Indeks keanekaragaman plankton tertinggi pada titik 5 sebesar 2.202 dan terendah pada titik 3 sebesar 1.549. Indeks keseragaman tertinggi pada titik 5 sebesar 0,858 dan terendah pada titik 4 sebesar 0,687. Dominasi tertinggi pada poin 3 sebesar 0,269 dan terendah pada titik 5 sebesar 0,169. Hubungan antara parameter fisika-kimia dan keanekaragaman plankton menunjukkan bahwa kecepatan aliran arus  berpengaruh paling signifikan terhadap keanekaragaman plankton di estuari Sungai Selan.   Plankton are tiny living organisms that float in the water column and are an important component of aquatic ecosystems. This study aims to determine the physico-chemical parameters of the waters, plankton composition, and the correlation between the diversity of plankton and the physico-chemical parameters of the waters using statistical analysis. This research was conducted in June 2022 at the Selan River estuary in Central Bangka Regency. The research was conducted in the morning. Plankton data collection was carried out using the vertical pull method using a plankton net. The resulting plankton samples were identified under a microscope with three replicates for each sample at each observation point. The results showed that 24 types of plankton were found in the Selan River estuary. The highest plankton abundance was at point 4 with 701.38 ind/L, and the lowest was at point 1 with 197.91 ind/L. The highest plankton diversity index was at point 5 of 2,202, and the lowest was at point 3 of 1,549. The highest uniformity index is at point 5 of 0.858, and the lowest is at point 4 of 0.687. The highest dominance is at point 3 of 0.269, and the lowest is at point 5 of 0.169. The relationship between physico-chemical parameters and plankton diversity shows that current velocity significantly affects plankton diversity in the Selan River estuary.

Abstract

The distribution and enrichment of heavy metals in sediments will affect the life of the organisms that lives in it. The purpose of this study is to explain the enrichment and contamination levels of heavy metals Cu and Pb in bulk sediments in the northern and southern parts of Bangka Island. This research was conducted in August - September 2019, using a purposive sampling method. Heavy metal analysis using the Inductively Coupled Plasma - Optical Emission Spectroscopy (ICP-OES) instrument. The results showed that the concentration of the heavy metal Pb in the sediment bulk of northern Bangka Island (Kelabat Bay) was higher than that of South Bangka Island. The concentration of heavy metal Cu at 8 (eight) sites is still below the quality standard (18.7 mg.kg-1) even if the heavy metal Pb at stations 3, 4, and 5 in the waters of the northern half of Bangka Island (Kelabat Bay) is reported to have exceeded the quality standard limit (30.2 mg.kg-1). The highest level of enrichment of heavy metal Pb occurs at station 4 with a value of EF_62.88, and is categorized as very high enrichment and a contamination factor (CF) value of 2.24 (medium category). This condition is due to station 4 being located in Kelabat Bay (semi-enclosed area) with unstable water conditions due to the influence of many activities. The results of this study can be used as input for local governments for the management of water areas on Bangka Island.

Abstract

In the current era of globalization, students are faced with demands to consider the factors that influence the achievement of their learning outcomes. This research aims to reveal the role of an effective school environment and parental attention in improving the quality of student education. Quantitative methods were used in this research. In this research, this approach was chosen to provide a more measurable understanding of the role of the school environment and parental attention on student learning outcomes. The research population includes all students of SMA Negeri 1 Ketapang Sampang so that the research results can be more generally applied to this group. The use of multiple linear regression as a data analysis tool allows researchers to understand the extent to which certain variables, such as school environment and parental attention, contribute to variability in student learning outcomes. The findings show that the school environment has a fairly large role in determining student learning outcomes. Apart from that, emotional involvement and parental support also play a role in developing student academic achievement. With a school environment that supports learning and positive contributions from parents, it is hoped that student learning outcomes will improve.

Abstract

Cultivating fattening mud crabs (Scylla serrata) usually requires a large area of land, innovation is carried out by making crab apartments. The research was conducted in September – November 2023, crab fattening locations in Pagarawan Village and Takari Beach, Bangka Regency. Location of mud crab morphometric measurements at the Aquatic Resources Management Laboratory, Bangka Belitung University. Test protein content at the DKI Jakarta Regional Health Laboratory. This research aims to examine the morphometrics, protein content and survival of mud crabs in crab apartments in Pagarawan Village and Takari Beach. Experimental research methods and community involvement to measure morphometrics, protein content and crab survival. The results of the research show that the ratio between weight, width and length of mangrove crabs in Pagarawan is 1.6:1.4:1. This shows that mud crabs are fatter. When the crab weighs around 160 grams, it is likely that the carapace width is ±14 cm and the carapace length is ±10 cm, while the crabs in Takari are smaller and thinner. The protein content of mangrove crabs in Pagarawan has an average value of 17.5 gr/100gr and in Takari 15.1 gr/100gr. The survival rate (SR) of mangrove crabs in Pagarawan is 87%. This condition means that crabs are suitable for cultivation in crab apartment boxes with a water source from a recirculation system pond. It is assumed that water pollution due to ammonia will not have much of an impact. The survival rate for mud crabs in Takari shows a zero percentage. The narrow space, food waste, and circulating water with an ammonia content of up to 0.05 mg/l are thought to have contributed to the crab's death. Water quality in both crab rearing areas shows that temperature, pH, salinity, DO, ammonia, nitrate and phosphate are still within the normal range for rearing mud crabs.
