The media was tested by learning media experts and learning material experts. The score obtained from learning media experts is 88% while the score from learning materials experts is 90%, both of which fall into the very feasible category. The student response test was conducted at MA Al-Khairiyah Rancaranji with a total of 17 students. The results of the student response test showed that the M3DB learning media was included in the appropriate category (79%). The assessment category means that the M3DB learning media is worthy of being used as a learning medium in schools

Freshwater Trophic State of Sindang Heula Dam in Terms of Chlorophyl Content

This study aims to determine the trophic status of the waters of Sindang Heula Dam in terms of chlorophyll-a content and its relationship with other water parameters. The study was conducted in April 2021. The sampling location was determined by purposive sampling method with 5 stations. Sampling of chlorophyll-a was carried out using a composite sampling technique, which was then tested by spectrophotometric methods. Physical and chemical parameters of the waters measured included temperature, brightness, TSS, pH, DO, BOD, nitrate, nitrite, and phosphate. The results showed that the content of chlorophyll-a ranged from 12,733–63,457 g/L. Based on the results of the study, the waters of the Sindang Heula Dam have a eutrophic status to hypereutrophic, this indicates that the waters have been heavily polluted due to high levels of nutrients. ABSTRAK: Penelitian ini bertujuan untuk mengetahui status trofik perairan Bendungan Sindang Heula ditinjau dari kandungan klorofil-a serta hubungannya dengan parameter perairan lainnya. Penelitian dilakukan pada bulan April 2021. Lokasi pengambilan sampel ditentukan dengan metode purposive sampling sebanyak 5 stasiun. Pengambilan sampel klorofil-a dilakukan dengan teknik composite sampling, yang selanjutnya diuji dengan metode spektrofotometri. Parameter fisika dan kimia perairan yang diukur meliputi suhu, kecerahan, TSS, pH, DO, BOD, nitrat, nitrit, dan fosfat. Hasil penelitian menunjukkan bahwa kandungan klorofil-a berkisar 12,733–63,457 μg/L. Berdasarkan hasil penelitian maka perairan Bendungan Sindang Heula memiliki status eutrofik menuju hipereutrofik, hal ini menunjukkan perairan sudah tercemar berat akibat tingginya unsur hara

Research Implementation of the Milkfish Feed Development from the Edible Mushrooms for a Digital-Based Module in Biotechnology Concept for High School Students

This study aimed to analyze the results of research on the content of edible mushrooms as milkfish feed to be implied as a digital module, a learning source for biotechnology concepts for high school students. The study was carried out through stages: identifying the problems in biotechnology concepts learning activities in four state senior high schools in Banten Province, identifying research methods and products through experiments, choosing and adapting research findings as the learning source content, and applying and developing research findings as learning. An interview grid and questionnaire were used to collect the data, and a qualitative analysis was used to interpret the questionnaires' results. The research results were in the form of a digital-based module in biotechnology concepts for high school students. The module contains activities that create student interest and motivation and help students master the concepts. In addition, the module's content was a research finding on the milkfish feed development from the edible mushrooms in the form of process and product. It can be concluded that a digital module on biotechnology concepts has been developed and can be used as a learning source for high school student.</p

Studi Kasus SMA di Banten: Proses Pembelajaran Biologi SMA Melalui Pendekatan Saintifik dalam Mengembangkan Keterampilan Pemecahan Masalah Siswa
