Abstract

Identifikasi Kandungan Mikroplastik Pada Ikan Kiper (Scatophagus argus) dan Ikan Nila (Oreochromis niloticus) di Perairan Sungai Somber, Kota Balikpapan Kalimantan Timur. Bertujuan untuk mengetahui jenis kandungan mikroplastik pada ikan kiper dan juga ikan nila yang berada di sungai somber. Ketergantungan manusia dengan pemakaian plastik menghasilkan sampah plastik dalam jumlah yang banyak karena sering dimanfaatkan dalam berbagai hal salah satunya bahan kemasan. Polimer plastik tidak dapat mengalami degradasi secara biologi, namun dapat dipecah oleh radiasi ultra violet dan energi mekanis menjadi fragmen polimer menjadi lebih kecil. Mikroplastik dapat tertelan oleh organisme laut karena partikel tersebut menyerupai makanan. Hasil penelitian menunjukkan bahwa pada ikan kiper (Scatophagus argus) dan ikan nila (Oreochromis niloticus) mengandung partikel mikroplastik diantaranya berjenis fiber, fragmen, dan film, dengan partikel mikroplastik jenis fiber dan fragmen yang mendominasi. Pada ikan kiper (scatophagus argus) ditemukan mikroplastik berjenis fiber, fragmen, dan film dengan ukuran partikel berkisar antara 453,03 µm – 2329,13 µm, 12,04 µm – 242,71 µm, dan 19,06 µm – 83,83 µm.

Abstract

The situation where there is a mismatch between the student's initial concept and the conception put forward by the expert results in students being very confident in the wrong concept or called a misconception. There are several circumstances that can lead to misconceptions. This study used Three-Tier Multiple Choice diagnostic examination with the help of Google Form to determine the misconceptions and contributing variables held by students of class XI at SMAN 16 Samarinda regarding the material of the excretory system. The researcher used a descriptive research design using a sample of class XI-2 which amounted to 33 students. Based on the results of data analysis, students' concept understanding of the excretory system material is divided into four categories, namely understanding the concept (60%), understanding the concept but not sure (3%), misconceptions (23%), and not understanding (14%). The majority of misconceptions were in the category of questions about urine formation and anatomy and physiology of parts of the excretory system. The average misconception is 23%, the level of student misconceptions is included in the low group. Factors causing misconceptions in students are due to themselves such as students' learning abilities and lack of interest in learning, while from outside themselves such as less conducive classroom conditions, lack of laboratory tools and materials, students who do not dare to ask questions and are not focused, students who still learn overnight, and limited learning time so that the explanation cannot be conveyed in full.  Keywords: Misconception, Test Diagnostic Three-Tier Multiple Choice, Google Form

Abstract

Staphylococcus aureus adalah bakteri yang secara medis penting yang sering ditemukan pada kulit atau permukaan hidung. Bakteri ini dapat menyebabkan berbagai infeksi, dari yang ringan hingga yang berat, dan berkontribusi terhadap peningkatan angka kematian. Untuk mengatasi infeksi ini, antibiotik yang mampu menghambat atau menghilangkan bakteri ini sangat penting. Tanaman lokal, yang sering digunakan sebagai tanaman hias dan obat, merupakan sumber potensial antibiotik tersebut. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak metanol daun kenikir (Cosmos caudatus Kunth.) dalam menghambat pertumbuhan S. aureus. Penelitian ini menggunakan desain eksperimental laboratorium dengan enam perlakuan: empat konsentrasi ekstrak (100%, 75%, 50%, dan 25%), kloramfenikol sebagai kontrol positif, dan metanol sebagai kontrol negatif. Hasil penelitian menunjukkan bahwa konsentrasi ekstrak metanol 75% menghasilkan zona hambat rata-rata sebesar 5,6 mm yang dikategorikan lemah. Temuan ini menunjukkan bahwa ekstrak daun kenikir menunjukkan beberapa efek penghambatan terhadap pertumbuhan S. aureus ATCC 25923. Namun, kemanjurannya yang lemah menyoroti perlunya eksplorasi lebih lanjut untuk meningkatkan potensinya sebagai agen antibakteri. Penelitian ini menggarisbawahi pentingnya mengevaluasi tanaman lokal untuk khasiat obat mereka untuk mengembangkan pengobatan alternatif untuk infeksi bakteri.

Abstract

One economically valuable horticultural vegetable crop is cayenne peppers (Capsicum frutescens L.). Because plant pests contribute to the reduction in cayenne pepper production, this study aims to determine whether the leaves of the Leucaena leucocephala and the seeds of the Swietenia macrophylla King can be used as botanical pesticides to control pests that attack cayenne pepper plants. An innovative experimental approach was applied in this study. This study utilized a Randomized Block Design (RAK) with 125 plants, which included 5 treatments, 5 replications, and 5 groups. We shall undertake this research for a duration of three months. The research was conducted in the yard of the researcher's house in Long Iram City, West Kutai Regency, East Kalimantan. The purpose of the study was to determine the effectiveness of a botanical pesticide on Cayenne Pepper plants. The researchers found that a combination of Lamtoro Leaf extract (Leucaena_Leucocephala) and mahogany seeds (Swietenia macrophylla King) reduced the intensity of insect pest attacks. The T4 treatment, which contained 70% of the extracts, was the most effective botanical pesticide for the plants.
