Abstract

Media and teaching materials that suit learning needs can improve the quality of learning. The research aims to describe the use of media and teaching materials in science learning. The type of research is a survey. Research in June-September 2023 at Middle Schools in the Greater Malang Region. The research population was junior high school students and teachers in the Greater Malang area. The research sample was 584 students and 18 teachers. The data collection technique uses a media and learning material needs analysis questionnaire. The research instrument is a needs analysis questionnaire sheet. Data was analyzed descriptively, quantitatively, and qualitatively. The research results show that the media and teaching materials used by teachers are quite good, but teachers rarely use a variety of media and teaching materials. The learning media that teachers often use are learning videos and the teaching materials that are often used are textbooks. Science learning still requires supporting media and teaching materials, one of which is expected to be an e-module

Abstract

This research aims to explore the characteristics of trichomes from the Fabaceae family. This type of research is exploratory descriptive research. Direct exploration and laboratory observation methods were used in the research. This research was carried out from March 2022 to January 2023. This research was carried out at the UMM Malabar City Forest and Biology Laboratory. Observation of trichomes using SEM. The research data obtained were analyzed using descriptive statistics. The results of the research show that there are variations in the characteristics of Fabacea family trichomes in the Malabar forest of Malang City. There are two varieties of trichomes, there are three forms of trichomes, namely subulate, osteolate and globular, the highest average number is Bauhinia purpurea leaf trichomes and the fewest are Albizia chinensis and Senna siamea, the trichomes with the longest size are Delonix regia and the shortest are Erythrina trichomes variegata, the narrowest trichomes are A. chinensis and the widest are E. Variegata. The results of the research can be used by stakeholders to become a consideration for selecting plant species in city parks by using plants that can help improve air quality in addition to considering aesthetics.

Abstract

Jenis penelitian yang digunakan adalah penelitian deskriftif kuantitatif. Penelitian ini dilakukan pada bulan FebruariMaret 2015. Tujuan penelitian ini adalah untuk mengetahui keanekaragaman makrofauna tanah, kandungan C-organik dan organophosfat tanah. Metode dalam penelitian ini adalah jebakan (pitt fall trap) untuk mengetahui keanekaragaman makrofauna tanah dan analisis laboratorium untuk mengetahui kandungan C-Organik dan organophosfat tanah. Hasil penelitian menunjukkan bahwa (1) Kepadatan berkisar antara 0,25 ind/m2–4,75 ind/m2, kepadatan relatif berkisar antara 0,002-0,052. Frekuensi berkisar antara 0,16–1,00, frekuensi relatif berkisar antara 0,018–0,115. Indeks keanekaragaman jenis Shannon wiener (H’) kategori keanekaragaman jenis rendah. Hasil Uji C-Organik tanah sangattinggi berarti tanah tergolong tanah yang subur. Organophosfat jenis Carbokfuran sangat tinggi
