Abstract

The problem of waste in the school environment can increase the density of flies as a vector of disease transmission. This study aims to analyze the influence of waste management education on students' knowledge and describe the density of flies in the Sunggal Islamic College Foundation. The research uses a quantitative method with a pre-experimental design through a one group pretest-posttest approach. The sample amounted to 40 grade IX students who were selected by purposive sampling. Data was collected using questionnaires to measure knowledge before and after education as well as observation of fly density at several points in the school environment. Data analysis was carried out univariate and bivariate using the Wilcoxon test with a significance level of p<0.05. The results showed that the proportion of students with good category knowledge increased from 70.0% to 92.5% after education. The Wilcoxon test produced a p-value of 0.005 which shows a significant influence of education on improving student knowledge. Observations showed that the highest density of flies was in the canteen and garbage can areas after breaks, while the field area remained low. Waste management education has been proven to be effective in increasing student knowledge and supporting the creation of a cleaner and healthier school environment.

Abstract

Kerja kelompok sudah menjadi bagian penting dari aktivitas kuliah, tapi dalam praktiknya, tidak semua mahasiswa terlibat secara seimbang. Selalu saja ada anggota kelompok yang hanya ikut nama, tapi tidak benar-benar ambil bagian dalam menyelesaikan tugas. Inilah yang dikenal dengan istilah social loafing, yaitu ketika seseorang cenderung mengurangi kontribusi karena merasa tanggung jawabnya bisa dibagi rata ke anggota lain. Penelitian ini melibatkan 54 mahasiswa dari berbagai fakultas di Universitas Islam Negeri Sumatera Utara. Hasil menunjukkan bahwa 88,9% responden pernah berada dalam kelompok yang anggotanya tidak aktif. Hal ini membuat mahasiswa lain merasa terbebani, dan semangat kerja kelompok pun ikut menurun. Alasan paling umum dari kurangnya kontribusi adalah tidak peduli terhadap tugas. Untuk mengatasi situasi ini, mayoritas mahasiswa menyarankan agar sejak awal tugas dibagi dengan jelas, ada komunikasi terbuka, dan dosen ikut mengevaluasi kinerja setiap anggota. Penelitian ini menunjukkan bahwa social loafing bisa dicegah jika kelompok dibangun dengan rasa tanggung jawab yang adil, saling menghargai, dan memiliki aturan main yang disepakati sejak awal.
