Abstract

Wana Wisata Rowo Bayu berada di kawasan hutan Petak 8, Forest Resort Songgon, Hutan Rogojampi, Kecamatan Songgon, Kabupaten Banyuwangi. Rowo Bayu berada pada ketinggian 630 meter diatas permukaan laut dan memiliki 3 sumber air dan rowo, sehingga menjadikan wilayah tersebut memiliki kelembaban udara yang tinggi.Kondisi tersebut memungkinkan untuk beberapa jenis hewan dapat hidup, terutama kelompok herpetofauna. Sampai saat ini, belum banyak penelitian tentang herpetofauna di kawasan tersebut.Penelitian ini bertujuan untuk mendeskripsikan persepsi masyarakat terhadap konservasi herpetofauna, mendeskripsikan diversitas, memetakan persebaran dan deskripsi habitat, serta menentukan karakteristik herpetofauna diurnal di Wana Wisata Rowo Bayu. Metode yang digunakan dalam penelitian ini meliputi wawancara semi terstruktur, morfometri,Visual Encounter Survey (VES), dan fences trap.Berdasarkan hasil penelitian didapatkan 4 titik lokasi penting ditemukannya berudu yaitu Rowo Bayu, Sumber Kamulyan, Sumber Dewi Gangga, dan Sumber Kaputren,  serta 1 titik yang merupakan mikrohabitat Microhyla. Spesies yang didapatkan dari fences trap adalah Huia masonii(Boulenger, 1884). Famili yang didapatkan darimetode VES yaitu 3 famili dari kelas anura yaitu Microhylidae, Ranidae, dan Dicroglossidaedan 4 famili dari kelas reptil yaituScincidae, Agamidae, Colubridae, dan Natricidae. Kawasan Wana Wisata Rowo Bayu didominasi oleh berudu dari genus Microhyla. Hasil analisis Principal Component Analysis (PCA) menunjukkan ciri karakteristik Eutropismultifasciata adalah Snout Vent Length (SVL), ciri karakteristik Hylarana rufipes adalah Hind Limb Length (HLL), tetapi ciri karakteristik Microhyla achatina tidak diketahui karena ukuran tubuh sangat kecil. Berdasarkan hasil wawancara, seluruh responden mendukung upaya konservasi dengan cara tidak merusak atau mengganggu habitat herpetofauna.

Abstract

Program adiwiyata bertujuan untuk meningkatkan kapasitas sekolah dalam mewujudkan sekolah peduli dan berbudaya lingkungan, menanamkan pendidikan dan cinta lingkungan. Kota Batu telah mengikuti program adiwiyata sejak tahun 2008 dan telah mendapatkan penghargaan adiwiyata bagi 15 sekolah dari 147 sekolah yang ada di Kota Batu. Berdasarkan kondisi tersebut, dirumuskan permasalahan sebagai berikut : (1) Bagaimana ketercapaian indikator penilaian adiwiyata dalam pengelolaan sekolah adiwiyata di Kota Batu (2) Apa saja yang menjadi faktor pendukung dan faktor penghambat?, (3) Bagaimana merumuskan strategi pembinaan sekolah adiwiyata di Kota Batu? Penelitian ini bertujuan menjawab permasalahan tersebut dengan menggunakan metode analisis deskriptif kuantitatif dengan teknik analisis IFAS-EFAS. Kesimpulan analisis sebagai berikut : (1) aspek partisipatif adalah aspek yang paling lemah pada sekolah adiwiyata nasional, provinsi dan kota. (2) penilaian faktor internal dan eksternal, menunjukkan bahwa sekolah adiwiyata mandiri dan nasional memiliki kekuatan dan peluang yang paling tinggi dibandingkan adiwiyata provinsi dan kota. Posisi adiwiyata mandiri dan nasional pada kuadran I (1,35 ; 0,8), adiwiyata provinsi dan kota pada kuadran II (1,35 ; -0,15) dan (0,2 ; -0,95). (3) strategi prioritas adiwiyata mandiri: strategi keberlanjutan, adiwiyata nasional: strategi pengembangan, adiwiyata provinsi: strategi pertumbuhan dan adiwiyata kota: strategi perencanaan.

Abstract

Genetic diversity of sea urchin are very high; there are no two organisms of the same species that are exactly alike. Dense aggregation of sea urchin is responsible for the destruction of marine algae communities on coral reef ecosystem. The purpose of this study is to identify the species and abundance of sea urchins at different environmental conditions, to analyze the influence of water conditions on the abundance of sea urchins and to analyze the role of sea urchin as water quality and abiotic environmental conditions bio-indicators. Data collection procedures carried out in three stage that are: assessment of the status of coral reefs, sea urchins sampling and analysis of data. Data condition of coral reefs is drawn using methods kick frequency. Urchin abundance data retrieval is done by timed swims or snorkeling and species of sea urchins seen through genetic approach, by DNA sequencing. Identify the types of sea urchins in this study conducted with the gene fragment sequences Cytochrome Oxidase subunit I (COI). Stages isolation of DNA-based procedures uses Gsync DNA Extraction Kit from Geneaid. The species that identify in this study is Diadema setosum. Location with high environmental pressures has a low quality of coral reef ecosystems and has a great abundance of sea urchins. This proves that the water environmental conditions greatly affect the abundance/density of sea urchins. In locations with relatively low environmental stress or a sheltered environment the abundance of sea urchins is low.

Abstract

A study on soil arthropod abundance, diversity and composition have been done on November 2016 to March 2017 using pitfall traps. The objective of this study is to analyze variations of the soil arthropod abundance, diversity and composition among different habitats in a university forest.  The study was carried out in Universitas Brawijaya Forest (UBF) Malang, East Java (7°49'S, 112°34'E, 1,200 m in altitude), consisted of four locations: an agroforestry (AF), a gallery forest (GF), the pine stands (PS) and a settlement yard (SY). At each site, a total of 10 traps (5 by 2 rows) were placed systematically at 4-m intervals. Glass cups (10 cm in diameter and 7 cm deep) were buried in the ground during 24 hours. There were 2286 individuals of arthropod collected from all sampling locations. Overall the samples collected consist of 41 families of arthropods. The abundance (mean ± SE) of soil arthropod was highest in PS and the lowest in SY. Statistically, variations in abundance among locations were significant (F = 7.39, p < 0.01). The taxa richness of arthropod was highest in GF and the lowest in SY. Statistically, variations in taxa richness among locations were significant (F = 4.26, p < 0.05).  The diversity was the highest in the GF (1.9 ± 0.1) lowest in the SY (0.74 ± 0.1). Statistically, variations in diversity among study sites were significant (F = 26.73, p < 0.001). In general, scavenger dominated the composition of soil arthropods. The highest proportion of scavenger abundance present in SY was 84.9%, while the lowest in the GF was 29.3%. The highest litter transformer composition in GF was 33.9%, and the lowest in SY was 8%. The highest decomposer in PS was 26.9% and the lowest in AF was 12.9%. The highest predator in AF was 20.7% and the lowest in SY was 1%. Compositions of soil arthropod were affected by environmental factors such as soil temperature and light intensity.
