Abstract

The Taplel waterfall area which is in the Sisimeni Sanam Education and Training Forest area is one of the conservation areas in East Nusa Tenggara which has quite high biodiversity, including plants that produce natural colors. However, information on the species diversity of dye plants in the Taplel waterfall area is still lacking. The objective of this study was to uncover the diversity of natural dye plants in the Taplel waterfall area, Sisimeni Sanam Training Forest, Takari District, Kupang Regency. Data collection was carried out by setting sample plots measuring 2 x 2 meters (seedlings), 5 x 5 meters (saplings), 10 x 10 meters (poles), and 20 x 20 meters (trees). Analysis of the importance of species using the Importance Value Index, and species diversity using the Species Diversity Index (Shannon-Wiener Index). Species of natural dye plants found in the Taplel Waterfall Area include Tectona grandis, Cassia siamea, Acacia auriculiformis, Tamarindus indica, Ficus racemosa, Leucaena leucocephala, Schleichera oleosa, Bauhinia purpurea, Cassia fistula, Garuga floribunda, and Annona squamosa L.. Plant species that has the highest important role in the Taplel Waterfall Area is Cassia fistula (sapling), Bauhinia purpurea (pole), and Tectona grandis (tree). Meanwhile, the diversity of natural dye plant species in the Taplel Waterfall Area at the level of seedlings, saplings, poles and trees is in the moderate category.

Abstract

Marine biota has many benefits for human life. Sponges are a species of marine biota that can be used as a producer of antimicrobial compounds. The bacteria found in sponges have an important role in the continuity of life in the sea. The symbiotic lifestyle that occurs in bacteria and sponges has the opportunity to form substitutions for the content of secondary metabolites and enzymes, especially extracellular enzymes (amylase, protease, cellulose and lipase). This study aims to determine how to isolate sponge symbiotic bacteria and identify spongy symbiotic bacteria. The method used is purposive to take sponges. Characterization of bacteria was carried out based on morphology and gram staining. Enzymatic bacterial selection was carried out by testing the activity of the amylase enzyme (soluble starch), lipase enzyme (Teen 80), protease enzyme (skim milk) and cellulose enzyme (carboxyl methyl cellulose). Data analysis was performed in a qualitative descriptive manner by measuring the clear zone in the extracellular enzyme test results. Meanwhile, other research parameters measured in this study were temperature, salinity and pH. The results showed that out of 47 isolated bacteria and 33 of them had extracellular enzymes with 10 bacteria had amylase enzymes, 27 bacteria had lipase enzymes, 2 bacteria had protease enzymes and 1 isolate had cellulose enzymes.

Abstract

Rhyzophora stylosa Griff is a mangrove plant that grows on the coast of Bokunusan village, Semau District, Kupang Region. Endophyte fungi are found in plant tissues and can function as agents for controlling pathogenic pests. The purpose of this research was to isolate and identify   endophyte fungi found in the young and mature leaf of R. stylosa Griff at the Mangrove forest, Bokunusan Village, Semau District, East Nusa Tenggara. This research was conducted from November to December 2023 at the Microbiology Laboratory; Biology Study Program, Aretha Wacana Christian University. The method used was the Potato Dextrose Agar (PDA) media and fungal identification based on macroscopic and microscopic characteristics. Based on the results of the study, nine isolate was isolated from young and mature leaf of R. stylosa Griff.   Two endophyte fungi were obtained from R. stylosa Griff leaves. The endophyte fungi found were genus Aspergillus and Trichoderma.

Abstract

Makroinvertebrata merupakan hewan tidak bertulang belakang yang hidup melekat pada substrat. Jenis organisme ini berperan sebagai bioindikator kesehatan lingkungan. Tujuan dari penelitian ini adalah untuk menginventarisasi jenis-jenis makroinvertebrata yang terdapat di area ekosistem mangrove Oesapa Barat. Metode yang digunakan dalam penelitian ini adalah metode line transect. Teknik analisa data menggunakan analisa deskriptif kuantitatif. Berdasarkan hasil penelitian di area ekosistem mangrove Oesapa Barat ditemukan 17 spesies makroinvertebrata yang di kelompokkan dalam 4 kelas yaitu: Gastropoda, Bivalvia, Crustacea, dan Polychaeta. Indeks keanekaragaman spesies tertinggi terdapat pada transek II yaitu 1,68 sedangkan kepadatan, kepadatan relatif dan indeks dominansi tertinggi terdapat pada spesies C. Cobelti yaitu 9,67 ind/m2, 38,33% dan 0,14. Indeks keanekaragaman terendah terdapat pada transek III yaitu 1,22. Kepadatan, kepadatan relatif dan indeks dominansi ditemukan pada C. urceus, C. oulanense, Onchidium sp dan Uca sp yaitu 1,11 ind/m2, 0,44%. Indeks keanekaragaman di area ekosistem mangrove Oesapa Barat tergolong sedang. Salah satu bentuk usaha untuk melestarikan makroinvertebrata di lokasi penelitian adalah melakukan monitoring dengan pemantauan rutin polulasi makroinvertebrata serta melakukan penelitian lanjutan yang berkaitan dengan pola reproduksi atau siklus perkembangbiakan makroinvertebrata.

Abstract

Traditional medicinal knowledge represents an important biocultural resource for community-based healthcare and biodiversity conservation. This study quantitatively analyzed the use of medicinal plants for treating skin diseases among the Dawan (Amanuban) community in South Central Timor, Indonesia. A descriptive quantitative ethnobotanical design was applied through semi-structured interviews, field observations, and plant documentation involving 40 purposively and snowball-selected informants. Plant importance and knowledge consensus were assessed using Use Value (UV), Relative Frequency of Citation (RFC), Fidelity Level (FL), and Informant Consensus Factor (ICF). The study recorded 17 medicinal plant species used to treat seven categories of skin diseases, including dermatitis, boils, scabies, acne, itching, chickenpox, and cracked heels. A total of 276 use reports were documented, with leaves being the dominant plant part used. High ICF values (0.93–1.00) indicated strong consensus among informants. These findings demonstrate a structured traditional knowledge system and suggest priority species for future phytochemical, pharmacological, and conservation studies. Analisis Etnobotani Kuantitatif Penggunaan Tumbuhan Obat dalam Pengobatan Penyakit Kulit pada Masyarakat Amanuban, Indonesia ABSTRAK: Pengetahuan pengobatan tradisional merupakan sumber daya biokultural penting bagi kesehatan berbasis masyarakat dan konservasi keanekaragaman hayati. Penelitian ini menganalisis secara kuantitatif pemanfaatan tumbuhan obat untuk pengobatan penyakit kulit pada masyarakat Dawan (Amanuban) di Timor Tengah Selatan, Indonesia. Penelitian menggunakan desain etnobotani deskriptif kuantitatif melalui wawancara semi-terstruktur, observasi lapangan, dan dokumentasi tumbuhan terhadap 40 informan yang dipilih secara purposive dan snowball sampling. Tingkat kepentingan tumbuhan dan konsensus pengetahuan dianalisis menggunakan Use Value (UV), Relative Frequency of Citation (RFC), Fidelity Level (FL), dan Informant Consensus Factor (ICF). Hasil penelitian mencatat 17 spesies tumbuhan obat yang digunakan untuk mengobati tujuh kategori penyakit kulit, yaitu dermatitis, bisul, kudis, jerawat, gatal, cacar air, dan tumit pecah-pecah. Sebanyak 276 laporan penggunaan terdokumentasi, dengan daun sebagai bagian tumbuhan yang dominan digunakan. Nilai ICF tinggi (0,93–1,00) menunjukkan konsensus kuat antar informan. Temuan ini menunjukkan sistem pengetahuan tradisional yang terstruktur dan penting untuk penelitian lanjutan.
