Abstract

The research aims to analysis of the content of heavy metals cadmium (Cd) in milkfish (Chanos chanos Forsk) from the encroachment of Bima bay at year 2020. The benefit of this study is to provide information related to the content of heavy metals cadmium (Cd) in milkfish (Chanos chanos Forsk) and protect the community or consumers from heavy metal contaminants. The research was conducted in Bima Bay, namely in 2 research locations, namely Malay village, Bima City, and Palibelo, Bima Regency. This type of research is descriptive explorative research—sampling techniques using purposive sampling. Samples of milkfish were taken directly on the pond area of 3 heads in each location. Then the sample is put in the sample box that has previously been washed clean. The research samples were then analyzed of the content of heavy metal cadmium (Cd) using Atomic Absorption Spectrophotometer tool. The results showed that at the palibelo research site, Bima Regency in PB 1 samples contains cadmium (Cd) of 30 ppm, PB 2 samples of 40 ppm, and PB 3 samples of 10 ppm. Furthermore, at the location of Malay village, Bima City on KM 1 sample of 30 ppm, on KM 2 sample of 40 ppm, and KM 3 sample of 20 ppm. The content of heavy metal cadmium (Cd) in milkfish (Chanos chanos forsk) from Bima Bay exceeds the threshold by BPOM Regulation No. 5 of 2018 is 0.1 ppm. The presence of heavy metal content cadmium (Cd) that exceeds this threshold indicates that the waters of Bima Bay have been contaminated by heavy metals Cadmium (Cd).

Abstract

Kawasan Rumah Pangan Lesatri (KRPL) is one of the efforts that can be done to manage food security in the face of climate change. The management of the potential contained in KRPL is by applying Trigona sp honey bee cultivation which is integrated with agricultural land. The success of honey bee cultivation is highly dependent on the availability of feed in the environment. This study aims to determine the preferences of pollen collected by Trigona sp at KRPL. This type of research is a qualitative research with Chi square analysis. The research sample was bee pollen contained in 14 stup. The research was conducted from July-November. Data collection was carried out in October and November by making observations at KRPL with an area of 784 meters then making plant reference preparations that have the potential to be Trigona sp pollen feed in KRPL and comparing reference preparations with pollen preparations in Trigona sp stup. The results of the research at KRPL showed that there were 20 types of plant pollen in KRPL. The results of the descriptive analysis with chi square showed that there was a preference for the type of pollen that was fed to Trigona sp bees with a value of x2h > x2t so that H0 was rejected and Ha was accepted.

Abstract

Kegiatan budidaya lebah klanceng terintegrasi dalam Kawasan Rumah Pangan Lestari (KRPL) telah dilakukan sebagai salah satu upaya strategis dalam mitigasi dampak buruk perubahan iklim global. Secara lebih khusus, naskah ini mendeskripsikan jenis tanaman sumber pakan lebah yang disukai lebah dalam kawasan rumah pangan lestari, perkembangan koloni, dan produktivitas lebah, serta pemanfaatannya sebagai sumber belajar untuk pembelajaran biologi dan bidang terkait lainnya. Budidaya lebah klanceng yang terintegrasi dalam KRPL dilakukan untuk memperoleh data yang diperlukan. Hasil penelitian ini menunjukkan bahwa: a) dari sejumlah bunga yang tersedia, bunga matahari (Helianthus annuus L), tekokak (Solanum torvum), pepaya (Carica papaya L), belimbing (Averrhoa carambola L) merupakan sumber pakan pavorit bagi lebah klanceng (Trigona sp.) yang dibudidaya dalam Kawasan Rumah Pangan Lestari (KRPL); b) perkembangan koloni lebah Trigona sp yang dibudidaya di Kawasan Rumah Pangan Lestari (KRPL) sangat lambat dikarenakan ketersediaan pakan yang sangat terbatas; dan c) Kegiatan budidaya lebah klanceng di Kawasan Rumah Pangan Lesarai (KRPL) dapat memberikan manfaat tidak hanya bagi masyarakat pengelolanya, tetapi juga menjadi laboratorium alami yang sangat bermanfaat bagi pembelajar biologi, misalnya mahasiswa, dalam mempelajari berbagai hal yang muncul dalam budidaya ini.

Abstract

The aims of this study were to explore the perceptions of prospective science teachers towards ethnoscience studies in the songket cloth motif of the sasak tribe. This exploratory research conducted in three education study programs namely Biology, Chemistry, and Physics Education with 53 prospective science teachers involved as research subject. Closed questionnaire with likert scale and expertly validated applied for data collection. The data were analyzed by quantitative descriptive statistics, Anova test and t-test inferential statistics. The results showed that (1) perception of prospective science teachers has an average score in the "Good" category in terms of gender, regional origin, and study program; (2) there were no significant differences in the perceptions in male and female prospective science teacher based on t-test significance value of 0,455 > 0,05; (3) there were no significant difference in prospective science teacher’s perception refer to origin (native Lombok and non-native) based on t test significance value of 0,466 > 0,05; (4) there were no significant difference in the perception  of prospective science teachers in the biology, chemistry, and physics education study program based on Anova's significance value  of 0,423 > 0,05.
