Abstract

Perairan Indonesia merupakan daerah migrasi dari jenis-jenis mamalia air. Perairan laut Indonesia yang luas memiliki potensi sumberdaya hayati yang beranekaragam. Salah satu sumberdaya tersebut adalah mamalia laut, dimana semua anggota mamalia laut merupakan hewan yang langka dan di lindungi di seluruh dunia. Tujuan dengan adanya penelitian ini ialah untuk mengetahui tingkah laku mamalia didasar laut dan dipermukaan laut yang belum diketahui oleh banyak orang. Spesies yang diamati antara lain ikan paus (Cetacea), lumba-lumba (Delphinidae), anjing laut (Pinnipedia), dan dugong (Dugong dugon). Tingkah laku mamalia laut yang teridentifikasi selama pengamatan adalah berburu mangsa, melompat ke atas permukaan air, habitat yang disukai dan berenang menuju arah tertentu. Kata kunci: perilaku, mamalia, air

Abstract

The aim of the research is to find out the relationship between environmental literation and self-efficacy based on students’ academic level of the 10th grade of SMA Negeri 1 Limbangan on the learning material of ecosystem. Correlational study became the core of the research. The research was conducted in March 2024. The type of the research is correlational with the sample of 192 students, sampled using the purposive sampling technique, proved by average score of daily test. Data collection technique using a non-test instrument in form of self-efficacy questionnaire as well as an environmental literacy essay test. Research instrument used is a self-efficacy questionnaire consists of 10 statements to measure environmental literacy covering 25 questions. Data analysis using product moment correlation. The result obtained correlation coefficient between self-efficacy with environmental literacy showed the value of 0.616, ranged between 0.60 and 0.799, enough to show the strong correlation between both variables. The result of the research showed that there is a strong relationship between academic level with environmental literacy with the correlation coefficient as high as 0.40 – 0.599. The analysis concluded that there is a positive relationship between self-efficacy and environmental literacy based on the academic level.

Abstract

Misconceptions are common among students when solving mathematics problems and, if left unaddressed, may hinder their ability to understand the material. This study seeks to design and develop diagnostic test instruments—comprising questions and questionnaires—on algebra topics using the Appsheet application. The objectives are to assess the development process, feasibility, and effectiveness of the instruments, as well as to identify challenges faced during implementation. The research employed a Design Research approach with a development studies type, consisting of two stages: preliminary design and formative evaluation. The instruments underwent a one-to-one trial with three students, a small-group trial with six students, and a field test involving 33 eighth-grade students at SMP Negeri 1 Margaasih. Expert validation rated the instruments as “feasible.” Data were gathered through documentation, tests, and interviews. The instruments included 10 three-tier multiple-choice questions, a closed-ended questionnaire with 13 items, and interviews with both teachers and students. Analysis revealed that 3.9% of students understood the concepts, 8.2% exhibited positive misconceptions, 8.4% negative misconceptions, 22.1% general misconceptions, while 57.3% showed no conceptual understanding. These findings demonstrate that the instruments effectively identified algebraic misconceptions. Challenges encountered included limited school facilities for mobile device usage and occasional errors in the application when accessed simultaneously by many users, indicating the need for updates. Nevertheless, the Appsheet-assisted three-tier diagnostic test provides a feasible and promising tool for detecting misconceptions in junior high school algebra learning
