Abstract:
The existence of allegations about the presence of various mycorrhizae in the forest area of Fatusene Village, East Miomaffo District, North Central Timor Regency, is a benchmark for assessing the characterization of mycorrhizae in the area. The purpose of this study was to isolate and identify mycorrhizae in the forest area of Fatusene Village, East Miomaffo District, North Central Timor Regency. Mycorrhizal identification begins with sampling the soil under the tree stands using the quadratic method. Soil samples were taken randomly at three points per observation plot with a depth of 0-30 cm from the base of the tree trunk. Separation of spores from soil samples was carried out using a wet sieve technique. Data analysis was carried out descriptively by identifying morphological characters including the shape and color of the spores. The results of mycorrhizal research found in the research location of the forest area of Fatusene Village are endomycorrhizal types, especially arbuscular vesicles. Characterization of mycorrhizal spores showed that there were three different spore genera in soil samples, namely the genus Glomus, Gigaspora and Acaulospora. The three genus found in the soil samples at the study location were present in each dominant tree with different numbers of individuals. The spores of the three mycorrhizal genus found at the study site were 65 spores, with the distribution of 35 spores genus Glomus, 20 spores genus Acaulospora and 10 spores the genus Gigaspora. The characters the genus glomus are round, slightly round, oval and brown and dark brown in, have hyphae and are equipped with oily fluid spots on cook spores. The characters the genus Acaulospora are round and oval in shape, blackish brown in color, brownish red and brownish yellow, have several layers of cell walls, one of which is dark in color. The characters the genus Gigaspora are irregular in shape, somewhat round and round, yellow, brownish yellow, to yellowish brown, large in size and black spore walls. Conclusion The mycorrhizae found in the study site were endomycorrhizal, especially arbuscular vesicles which consisted of 3 genera, namely Glomus, Acaulospora and Gigaspora. The characters of the genus glomus are round to oval in shape, dark brown in color, have hyphae and spotting of oil. The characters the genus Acaulospora are round and oblong, brownish yellow in color, have several layers of cell walls. The genus Gigaspora is slightly round and round, yellowish brown in color, large and black spore walls.

Abstract:
Insect diversity is believed to be used as a bio-indicator of spring quality. This study aimed at determining the spring insect diversity around the Mutis Timau Nature Reserve. The study was conducted from June to August 2019. Insects were caught by using the yellow pan trap and hand sorting. The diversity of spring insects was determined based on the Shannon-Wienner diversity index (H'), species richness index (R1), species dominance index (D), and evenness index (E). The results showed that 16 species belong to 11 families, and 5 orders of insects. The families included Gryllidae, Gryllotalpidae, Tetrigidae, Formicidae, Pompilidae, Apidae, Ochteridae, Veliidae, Hydrometridae, Nepidae, Coenagrionidae, Libellulidae, Carabidae, and Coccinellidae. The Shannon-Wiener species diversity index and the wealth index of the species of springs were classified as moderate (H '= 2.12 and R1 = 4.19). There was no type of spring insects dominated (D = 0.23). All springs insects were found to have almost the same level of evenness (E<1), with a value of 0.76. Abiotic factors such as pH and soil temperature were within the tolerance range of spring insects. Key words: Insects diversity, Spring, Mutis Timau Nature Reserve

Abstract:
This study aims to analyze the communication skills of students by using the "Traditional Market Concept" learning model which then results are interpreted and processed based on the perspective and conception of the researcher. This research is descriptive quantitative research, in which the results of the assessment of communication skills will be processed into a descriptive form from the researcher's point of view. This research was conducted at the Equality School Package C PKBM Serumpun Tanah Laut with 19 research subjects. This research was conducted in 2 stages, namely before using the "traditional market concept" learning model and after using the "traditional market concept" learning model. The results of the research conducted indicate that this "Traditional Market Concept" learning model can develop the communication skills of students in the Equality Package C School of PKBM Serumpun Tanah Laut. However, this research is a small study and has not included the validation, practicality and effectiveness of the “traditional market concept” learning model. So it is recommended that further research be carried out in the future that can determine the validity, practicality and effectiveness of the "traditional market concept" learning model.

Abstract:
Isolasi bakteri asam laktat menggunakan sampel saluran pencernaan belut (Monopterus albus). Belut yang digunakan diperoleh dari pasar Yogyakarta. Hasil isolasi diperoleh sebanyak tigabelas isolat, bakteri hasil isolasi selanjutnya dikarakterisasi secara fenotipik untuk memilih bakteri asam laktat. Hasil karakterisasi fenotipik diperoleh tujuh isolat yang sesuai dengan karakter bakteri asam laktat (ciri bakteri asam laktat bersifat gram positif dan katalase negatif). Tujuh isolat tersebut kemudian diuji kemampuannya dalam menghambat pertumbuhan bakteri patogen (Aeromonas hydrophila, Staphylococcus aureus, dan Vibrio harveyi). Hasil yang diperoleh menunjukkan bahwa tujuh isolat bakteri asam laktat memiliki aktivitas antimikroba yang mampu menghambat pertumbuhan bakteri patogen. Penghambatan terhadap bakteri uji mengindikasikan bahwa bakteri tersebut mampu menghasilkan antimikrobia. Tiga terbaik dari tujuh isolat bakteri diidentifikasi secara molekular menggunakan gen 16Sr RNA dengan primer 27F (5'-AGAGTTTAGTCCTGGCTCAG-3') dan 1492R (5'-GGTTACCTTGTTACGACTT-3'). Hasil yang diperoleh menunjukkan bahwa tiga isolat bakteri merupakan spesies Lactococcus lactis.
