Abstract

This study aims to determine the difficulties of authentic assessment experienced by biology teachers in public high schools in the city of Binjai. This research is descriptive with quantitative and qualitative analysis. The sample in this research is 18 biology teacher taken by using purposive sampling technique. Data collection techniques are by filling in questionnaires, interviews, documentation and direct observation. The results showed that some of the biology teachers of SMA Negeri in Binjai City experienced obstacles while carrying out authentic assessment. Constraints faced by biology teachers include difficulties in instrument making, difficulties in filling out the assessment format, difficulty in assessing students' attitudes objectively. There are several factors that cause teachers to experience constraints when carrying out authentic assessment that is the number of students who are not ideal, lack of understanding of authentic assessment procedures, training and socialization of authentic assessment has not been maximal, facilities and infrastructure of schools that are less supportive. The difficulty level faced by teachers in the implementation of authentic assessment is quite difficult with the value of 61.01.Keywords: teacher constraints, authentic assessment, biology learning.

Abstract

Tapanuli Selatan termasuk satu dari banyaknya provinsi di Indonesia yang seringkali dilanda banjir dan longsor sehingga masyarakat mengantisipasi bencana alam tersebut dengan mengupayakan pemberian bekal bencana siaga. Tujuan dari penelitian adalah untuk mengetahui penyebab dan solusi banjir serta tanah longsor, serta mengidentifikasi dampak banjir yang terjadi di tiga kecamatan Tapanuli Selatan yaitu kecamatan Angkola sangkunur, Muara Batangtoru, serta Angkola selatan. Studi pustaka yang digunakan dalam artikel ini bertujuan untuk mengumpulkan dan membandingkan data serta tinjauan yang berkaitan dengan judul. Hasil data didapatkan bahwa banjir dan tanah longsor diakibatkan oleh aliran sungai yang penuh dengan sampah, penebangan hutan secara sembarangan, dan hujan yang terus menerus. Solusi didapatkan dengan 3 cara yaitu melalui kearifan lokal dengan melakukan pelestarian hutan, lubuk, dan ikan larangan, menggunakan bioteknologi akar rumput Vetiver sp. dalam menahan erosi, dan melaksanakan kegiatan FGD untuk membuka wawasan para petani yang tidak memahami konservasi sumber daya alam

Abstract

This study aims to determine the effect of plant growth regulators and seed cutting patterns on the induction of mangosteen shoot growth. The research was conducted at the YAHDI Tissue Culture Laboratory in Medan, North Sumatra, Indonesia, in 20245. The method used in this study was a Completely Randomized Design (CRD) with two factors: BAP concentration and seed cutting pattern. The data collected were analyzed using statistical analysis of variance (ANOVA) with Duncan's Multiple Range Test (DMRT) at a 5% significance level using SPSS 26. The results of the study show that the interaction between BAP concentration and seed cutting pattern significantly affected the time of shoot emergence, the number of leaves, and the shoot height. The best shoot emergence time was obtained with a BAP treatment of 4 mg/L using whole seed explants, which occurred at 1 MST (Month After Sowing). A BAP concentration of 2 mg/L with whole seed explants produced the highest number of leaves, with 8 leaves. The highest number of shoots was obtained from explants planted in a medium with 6 mg/L BAP, which resulted in 5.67 shoots. Whole seeds planted in a medium with 0 mg/L BAP produced the tallest plants, measuring 8.9 cm. The combination of BAP concentration and seed cutting pattern did not significantly affect the number of roots.

Abstract

In the 21st century, education demands students to master essential skills like problem-solving and creative thinking. However, some studies show that Indonesian students, especially in biotechnology, still struggle with these skills. This highlights the need for effective teaching materials, such as SSI-based modules to help students improve their skills. This study aimed to develop a feasible module-based SSI on biotechnology, improve problem-solving and creative thinking skills, and evaluate students' responses to the module-based SSI on biotechnology. The module was developed using the 4D model (Define, Design, Develop, and Disseminate). The sample for this study was 60 students in 11th Grade Science Class from MAN Pematangsiantar. The research findings were as follows: 1) The module feasibility categorized as “excellent” in both media design  and language, while model content categorized as “good” 2) The result of N-gain for problem-solving was 0.61 (medium) and creative thinking was 0.73 (high). 3) Students' responses to the module categorized as “excellent”. Based on these results, the module based-SSI on biotechnology is considered highly feasible and can be used as a learning material that enhances problem-solving and creative thinking skills.
