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

Penelitian ini bertujuan untuk mengetahui pengaruh variabel pelatihan dan kepemimpinan terhadap kinerja pegawai. Metode penelitian menggunakan deskriptif kuantitatif dengan jumlah sampel dalam penelitian ini yaitu sebanyak 53 responden dengan menggunakan teknik sampling jenuh. Teknik analisis data menggunakan regresi linear berganda dengan pengujian hipotesis yaitu uji-t dan uji-F. Instrumen yang digunakan kuesioner. Hasil analisa berganda di peroleh persamaan Y = 3,975 +0,623X_1 + 0,296X_2 .Hasil Uji-t, pelatihan (X_1) dengan nilai t hitung (7,977) t tabel (1,67591) dengan signifikansi 0,000 0,05. Artinya menerima hipotesis alternatif (H_1) dan menolak hipotesis alternatif (H_0). Hasil uji-t variabel kepemimpinan (X_2) dengan nilai t hitung (3,378) t tabel (1,67591). Artinya menerima hipotesis alternatif (H_2) dan menolak hipotesis alternatif (H_0). Variabel pelatihan dan kepemimpinan diuji secara simultan, dengan nilai F hitung (38,266) f tabel (3,19), artinya menerima hipotesis alternatif (H_3) dan menolak hipotesis alternatif (H_0). Nilai koefisisen determinasi mencapai 0,589 atau sebesar 58,9% yang berarti bahwa variabel pelatihan dan kepemimpinan mempengaruhi Kinerja pegawai pada Dinas Kepemudaan, Olahraga, Kebudayaan dan Pariwisata. Sementara sisanya sebesar 41,1% dipengaruhi oleh faktor-faktor lain di luar penelitian ini.

Abstract

Gampong ujong drien is a village located in Meureubo District, West Aceh Regency, Aceh Province, Indonesia. One of the activities carried out in Gampong Ujong Drien is community service aimed at empowering the potential of residents through the use of technology, especially the Village Information System (SIGAP). Panglima Laot is a fisherman leader who plays an important role in coordinating fisherman activities, resolving, and enforcing customary law. Panglima Laot also plays a role in regulating fishing and imposing sanctions on violators of customary law. This study will likely examine the conditions in Panglima Laot, their role in managing marine resources, and the factors that influence fishermen's perceptions of this role.
