Abstract

This study aims to provide an overview of the implementation of the New Student Admissions of the Public High School zoning system in Bangkinang kota district and the distribution of the house points of the new student admissions on the zoning system of Public High Schools in Bangkinang kota district which consists of 4 villages including, Langgini village, Bangkinang village, Ridan village and Kumantan village. This research uses a qualitative approach with descriptive methods, as well as a type of case study research. The location of the research was carried out in Public High School 1 and 2 Bangkinang kota, where the data sources in this study were primary data obtained from observations and interviews of the Student Representatives of each Public Senior High School in Bangkinang kota district, as well as sekundur data obtained through technical guidelines for the new student admissions. at the level of Public High Schools in Riau Province and reports on the implementation of the Admission of Public High School Students in Bangkinang District, the city for the 2020/2021 school year. The difference in the implementation of the new student admissions in 2019 and 2020 lies in the implementation of socialization which is carried out online which results in information related to the acceptance of New Students not evenly distributed to prospective new students or parents of students who are in the designated zone area.

Abstract

Ekosistem perairan merupakan komponen penting yang rentan terhadap perubahan lingkungan akibat aktivitas antropogenik yang dapat memengaruhi keberadaan mikroorganisme, termasuk bakteri Bacillus. Bacillus memiliki peran ekologis penting dalam siklus biogeokimia, sehingga penting untuk memahami keterkaitannya dengan kondisi lingkungan. Penelitian ini bertujuan untuk mengidentifikasi hubungan antara parameter lingkungan dengan kelimpahan Bacillus pada sedimen perairan di Sumatra Barat. Penelitian ini menggunakan pendekatan deskriptif korelasional dengan pengambilan sampel sedimen di 12 titik yang mewakili ekosistem pantai, muara, sungai, dan danau. Parameter lingkungan yang dianalisis meliputi pH, suhu, salinitas, oksigen terlarut (DO), total organic carbon (TOC), ammonium, nitrit, nitrat, fosfat, dan sulfat. Identifikasi Bacillus dilakukan mengacu pada ISO 7218:2007, sementara analisis statistik menggunakan uji ANOVA/Kruskal-Wallis dan korelasi Pearson/Spearman. Hasil penelitian menunjukkan Bacillus terdeteksi di seluruh lokasi dengan variasi kelimpahan. Korelasi positif yang kuat ditemukan antara Bacillus dan amonium (r = 0,725; P < 0,05), sedangkan parameter lain seperti pH, salinitas, dan sulfat hanya menunjukkan hubungan positif lemah (r = 0,084-0,473; p >0,05). Sebaliknya, DO, suhu, TOC, nitrit, nitrat, dan fosfat berkorelasi negatif namun tidak signifikan (r = (-0,072) - (-0,321); P > 0,05). Temuan ini menegaskan bahwa dinamika Bacillus lebih dipengaruhi oleh ketersediaan senyawa nitrogen, khususnya amonium, dibandingkan parameter lainnya. Berdasarkan penelitian ini, Bacillus berpotensi sebagai bioindikator kualitas perairan dan mendukung pengelolaan lingkungan serta aplikasi bioteknologi perairan.
