Abstract

Mikroplastik merupakan partikel berbahaya yang dapat masuk ke dalam sistem rantai makanan sehingga dapat berdampak pada kesehatan baik bagi biota air maupun mamalia. Penelitian ini bertujuan untuk mengetahui kandungan mikroplastik pada ikan gabus (Channa striata B) dan ikan baung (Mystus nemurus CV) di Samarinda. Metode pengambilan sampel dengan purposive sampling. Sampel ikan Gabus diambil dari 5 pasar, Sungai Mahakam, dan Waduk Benanga. Sampel ikan baung (Mystus nemurus C.V) diambil di Pasar Ijabah dan daerah aliran Sungai Mahakam. Analisis dilakukan di Laboratorium Kualitas Air Fakultas Perikanan dan Kelautan. Pengumpulan data dengan melarutkan sampel pada NaCl jenuh kemudian diamati dengan mikroskop. Hasil penelitian menunjukkan terdapat jenis fiber, fragmen, monofilamen dengan ukuran 20-350 µm dan didominasi ukuran <150 μm pada sampel ikan. Jika termakan oleh manusia atau mamalia dapat terjadi penyerapan ≤0,3% pada limpa namun masih dapat ditoleransi. Maka perlu tindak lanjut penelitian terkait kadar maksimal terjadinya akumulasi mikroplastik pada manusia.

Abstract

This research aims to produce a feasible interactive ebook based on multiple intelligence for 11th-grade students of Senior high school, determine the effectiveness of an interactive ebook based on multiple intelligence on excretion system to improve the critical thinking ability of 11th-grade students of Senior High School, determine the effectiveness of interactive ebook based multiple intelligence on excretion system to improve cognitive learning outcomes of 11th-grade students of Senior High School. The multiple intelligence-based interactive ebooks are designed by Flip PDF Corporate application with html5 output converted to the android application by web2apk. The method used for this development was research and development (R&D) with the 4D (Define, Design, Develop and Disseminate) research model. The sampling method for the study was conducted random sampling. Method using one experiment class and one control class. This research in SMA Negeri 1 Ngemplak. Data Collection Techniques were using interviews, visionary, pre-test, and post-test. Ebook validation was carried out by material and media validators. The data analysis technique used a quasi-experimental non-equivalent control group design with the multivariate test by IBM SPSS 24. The ebook has validation and got 92,6% from the biology teacher, that is mean the ebook is valid and possible to use in biology learning. The Effect size shows 0.290 for critical thinking and 0.159 for cognitive learning outcomes, which means ebook has a high effect on both abilities
