Abstract

Mount Rinjani area on the island of Lombok is unique in bioecology. It provides habitats for many species of birds, especially birds of Wallacea. Several studies on birds in this area have been done, but the conservation priority of these birds has not been determined. Based on this condition, the purpose of this research is to determine the priority of birds conservation in mount Rinjani areas. Exploration about the spesies of birds was started from Senaru Village to Segara Anak Lake. Abundance of each bird species was estimated using point count. Data analysis to determine the conservation priority used indicators that consist of endemicity, population status, species threatened and species management. The results showed that the birds species in mount Rinjani areas are composed of 32 species belonging to 20 families. Bird species that have high abundance were Amandava amandava (15.94%), Zosterops Montanus (15.70%), and Parus major (11.32%), while Ptilinopus melanospila and Anthus novaeseelandiae were in low abundance (0.23%). Analysis birds conservation priority in mount Rinjani areas indicates that Otus jolandae has the highest score (65) and should be the first priority for the conservation, while Philemon buceroides and Gallus varius with the same score (60) are the second priority.

Abstract

The utilization of organic waste as a cultivation medium is a crucial step towards promoting sustainable agriculture and mitigating environmental impact. This study aims to evaluate the effect of adding mushroom baglog waste on the population growth of earthworms (Lumbricus rubellus), serving as supporting material in invertebrate zoology. This quantitative research, employing a true experimental method (True Experimental Research), was conducted for 60 days in the researcher's yard at Kebon Kopi Complex, Pejeruk Village, Ampenan District, Mataram City. The research design utilized a completely randomized design with five treatments and seven replications. The applied treatments included P0 (0% mushroom baglog waste), P1 (25% waste), P2 (50% waste), P3 (75% waste), and P4 (100% mushroom baglog waste). The observed parameters were the number and weight of earthworms. Research data were analyzed using the ANOVA test and the Least Significant Difference (LSD) test. The analysis results indicated that the addition of mushroom baglog waste significantly affected the earthworm population (P<0.05), suggesting that different proportions of mushroom baglog waste can increase both the number and weight of earthworms.

Abstract

Pembelajaran biologi yang diterapkan oleh guru masih menggunakan pembelajaran kovensional yang hanya berpusat pada guru (teacher centered). Dalam era Revolusi Industri 4.0 dicirikan oleh transformasi dalam semua bidang ilmiah, pembelajaran abad ke 21 menuntut beberapa keterampilan, seperti kemampuan berkomunikasi, kolaborasi, pemikiran kritis, serta keterampilan dalam menyelesaikan masalah. Berdasarkan Hasil studi Programme for Intenational Student Assesment (PISA) 2018, bahwa  kemampuan  berpikir  kritis siswa masih rendah, hal tersebut dapat diketahui dari beberapa hasil penelitian dan hasil tes yang membuktikan Indonesia menempati peringkat  72  dari  77 negara. Tujuan penelitian untuk mengetahui pengaruh model problem based learning (PBL) terhadap kemampuan berpikir kritis pada siswa kelas XI SMA Neger 1 Praya Barat. Penelitian ini merupakan penelitian quasi eksperimen dengan desain non-equivalent control group design. Sampel dalam penelitian adalah kelas XI MIPA-1 dan kelas XI MIPA-2 SMAN 1 Praya Barat. Kemampuan berpikir kritis diukur menggunakan instrument dalam bentuk tes/essay. Analisis data dalam penelitian menggunakan analisis kovarian dengan uji asumsi klasik yaitu uji normalitas, uji homogenitas dan uji linearitas. Hasil penelitian menunjukkan bahwa terdapat pengaruh model PBL terhadap kemampuan berpikir kritis siswa kelas X SMA Negeri 1 Praya Barat dengan nilai signifikansi sebesar 0,004 < taraf signifikansi 0,05. Nilai rata-rata terkoreksi kelas eksperimen adalah 71,730 lebih besar dari kelas kontrol yakni 63,891

Abstract

Melon is an annual plant, growing creeping with a stem length of about 3 meters. The vegetative and generative growth of melons is influenced by genetic and environmental factors. Environmental factors that affect the growth of melons include the abundance of nutrients in the growing media. Research has been carried out on the effectiveness of vermicompost and NPK fertilizer treatment on melon vegetative growth, with the aim of analyzing the effectiveness of vermicompost in increasing stem length, number, length and width of leaves and stem diameter of melons. effectiveness of NPK fertilizer in increasing stem length, number, length and width of leaves and stem diameter of melons. Effectiveness of the interaction of vermicompost and NPK fertilizer in stimulating melon growth. Growth parameters were measured when the melon was 28, 29 and 30 days after planting, the data obtained was analyzed using Anova. The results showed that vermicomposti is effective in increasing stem length, total and leaf length, but is not effective in increasing leaf width and stem diameter of melons. Application of NPK fertilizer is effective in increasing stem length, total leaves, leaf length, leaf width and stem diameter of melon. The interaction between vermicompost and NPK fertilizer was not effective in stimulating melon growth.

Abstract

Gastropods are one of the phylum Mollusca classes having a single shell, normally spiral-shaped. This research aimed to analyze the Gastropod community structure (Mollusca Phylum) in the Intertidal Zone of Wakan Village, Jerowaru District, East Lombok Regency. The combination of line and quadrat transect was implemented to take samples in this study. The variables in the research include the type and quantity of Gastropods. There were 1.715 individual of Gastropod found in this study. They were included in 11 families and 17 species. The Gastropod species with the highest abundance value in station I and II was Strombus urceus with the abundance value of 12,8 ind/m2 and 5,72 ind/m2, respectively. Meanwhile, in station III, it was Terebralia sulcate with the abundance value of 3,4 ind/m2. The diversity index of Gastropods in the research location was categorized as medium (H’=2,32) with a stable divercity index (E=0,84) and a low domination index (C=0,14).

Abstract

Human activity in Bagek Kembar Ecotourism is increasing because it is a tourist destination and is close to residential areas. This activity has an impact on biodiversity, especially soil insects in the area. The aim of this research was to determine the structure of the soil insect community. This research is an exploratory descriptive research. Data collection was carried out 8 times in 2 months. Sampling was carried out at 3 stations, namely station 1 on the main ecotourism route, station 2 in the middle of the ecotourism area, and station 3 in the area near the coastline. Samples were taken using the pitfall trap method at 27 trap points. The research results found that 15 sub orders, 30 families, 40 species consisting of 2,525 individuals were found in Bagek Kembar Ecotourism. Station 1 found (825) individuals, station 2 (835) individuals and station 3 (874) individuals of soil insects. Hymenoptera has the largest proportion (31.2%), and the order Thichoptera has the lowest proportion (0.07%). Soil insect composition at station 1 (34%), station 2 (33%) and station 3 (32%).
