Abstract

Penelitian ini dilaksanakan pada pertengahan bulan November 2022 – Desember 2022. Tujuan penelitian ini adalah untuk mengetahui kelimpahan, keanekaragaman, keseragaman dan dominansi perifiton pada daun lamun Enhalus acoroides di perairan Dusun Malahing Kota Bontang Kalimantan Timur. Pengukuran kualitas air dilakukan dilokasi penelitian dan Laboratorium Kualitas Air Fakultas Perikanan dan Ilmu Kelautan, sedangkan untuk substrat tanah dilakukan di Laboratorium Ilmu Tanah Fakultas Pertanian Pengambilan sampel dilakukan di tiga titik stasiun dengan dilakukannya tiga kali pengulangan di setiap stasiunnya. Pengambilan sampel dilakukan menggunakan tiga bagian daun yaitu bagian ujung daun, tengah daun dan pangkal daun. Kisaran kelimpahan perifiton pada daun lamun Enhalus acoroides di perairan Dusun Malahing adalah 90 – 4460 ind/cm2. Kelimpahan perifiton pada ketiga stasiun di lokasi penelitian relatif tinggi. Hal ini disebabkan karena permukaan daun yang lebar dibanding jenis lainnya serta dipengaruhi dengan kandungan nitrat dan substrat yang berpasir lebih tinggi dibandingkan dengan stasiun lainnya.

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

The use of media-assisted learning models such as PBL combined with quizizz can increase students' capacity to carry out analysis. This research aims to determine students' analytical thinking abilities after implementing the problem based learning model assisted by quizizz media. The type of research is a quasi-experiment with a nonequivalent pretest-posttest control group design model with the research population being all students of SMA Negeri 16 Samarinda, totaling 316 students. Samples were taken using a purposive sampling technique, so that class X-1 was selected as the experimental group and class X-6 as the control group with a total of 26 students each. The data analysis technique uses an independent samples t test at a significance level of 5% with the help of SPSS version 25 for Windows. The test results show a sig value. 0.000 < 0.05, which means that problem based learning assisted by media based on the quizizz application has an effect on the analytical thinking abilities of class X students at SMA Negeri 16 Samarinda.

Abstract

Penelitian ini dilaksanakan pada bulan November – Desember 2022 di perairan Teluk Balikpapan Kalimantan Timur. Tujuan dari penelitian ini yaitu untuk mengetahui kerapatan lamun, kelimpahan serta struktur komunitas makrozoobentos di perairan Teluk Balikpapan. Pengambilan sampel lamun dan makrozoobentos dilakukan di 3 stasiun penelitian dengan menggunakan metode transek yang kemudian diidentifikasi di Laboratorium Budidaya Perairan Fakultas Perikanan dan Ilmu Kelautan. Spesies lamun yang ditemukan di perairan Teluk Balikpapan terdiri dari vegetasi tunggal yaitu E. acoroides. Makrozoobentos yang teridentifikasi terdiri dari 3 kelas yaitu Gastropoda, Bivalvia dan Echinodermata. Hubungan kerapatan lamun dengan kelimpahan makrozoobentos berdasarkan uji korelasi menunjukkan nilai korelasi -0.4936, artinya hubungan kerapatan lamun dan kelimpahan makrozoobentos tergolong sedang dengan arah berlawanan dimana semakin tinggi kerapatan lamun maka semakin rendah kelimpahan makrozoobentos.
