Local upland rice (Oryza sativa L.) is a type of cereal crop that has the potential for dry land areas. Farmers in Kupang plant upland rice/local rice that has been consumed and used for generations and is considered by the surrounding community as part of their ancestral heritage. The materials used in this research were local upland rice varieties as a result of exploration. The varieties of six local upland rice of Kupang studied in this research had different rice characters in terms of its weight, volume, density and yield.'Aen Molo' has the highest weight per grain and per 1000 grains, namely 0.024 g and 24.95 g, also the highest volume of 1000 grains of rice is 30 ml, while 'Aen Lekes' has the lowest weight per grain and per 1000 grains, namely 0.020 g and 19.66 g and also the lowest volume of 1000 grains, namely 23 ml. The Iodine test results showed that the local rice of Kupang was classified in the regular or non-glutinous rice group. Meanwhile, Alkali test results show that the six samples of local upland rice have a high gelatinization temperature which indicates that local upland rice in Kupang Regency has high amylose content.

Recently, exploration of natural antibiotic alternatives by utilizing medicinal plants is often carried out. Nutmeg plant (Myristica fragrans Houtt) is a tropical plant endemic to the Maluku Island and often used as medicine by local people. This study was aimed to isolate endophytic bacteria from the nutmeg plant and detect its potential as an antibacterial against pathogenic bacteria. The study is a descriptive observational study with a true experimental approach. Endophytic bacteria were isolated from several organs of the nutmeg plant such as leaves, leaf bones, stems, fruit flesh, and seeds and then tested for their inhibition against Staphylococcus aureus, Propionibacterium acne, and Escherichia coli. The results showed that: (1) the highest total population of endophytic bacteria was found in the seeds of nutmeg (7.5x104 CFU/ml), (2) ten isolates of endophytic bacteria were obtained with varying morphological characteristics, and (3) the detection of antibacterial activity showed that of the 10 isolates obtained, 4 isolates were able to inhibit the growth of Escherichia coli, namely isolate BEAD2, BEATD1, BEABJ 2, and BEABJ 1 with the diameter of the inhibition zones of each isolate being 3.4 mm, 3.2 mm, 1.6 mm and 1.5 mm respectively. The conclusion of this study is that 4 isolates of endophytic bacteria were detected as potential antibacterial against Escherichia coli.

Mosses or Bryophytes are a group of cryptogamous plants or lower plants. Moss can be found in various places that have high humidity by attaching to various substrates, such as soil, rocks and tree bark. PPKA Bodogol is a potential area that protects endemic flora and fauna on the island of Java that has excellent humidity and air for moss growth and supports moss diversity. This study aims to determine the diversity of mosses and their relationship to environmental factors in the PPKA Bodogol. Data collection in this study was carried out at the PPKA Bodogol on 3 routes, namely Cikaweni, Rasamala and Kanopi. This research uses a purposive sampling method with a cover square technique. The results showed that the total number of moss species identified were 21 species. Then it was also known that the highest level of diversity was found on the Rasamala route with a diversity index of 3.03. In the Cikaweni route, was in moderate category, namely 1,967. The lowest diversity index, however, was in the canopy path with a medium category, namely 1.216. Environmental factors such as humidity, temperature, light intensity, and altitude also had an influence on the level of moss diversity of the three routes.

The purpose of this study was to determine the diversity of phyla Echinoderms class Echinoidea and Holothuroidea at the Harbor Waingapu Old Pier and its use as a medium Biology learning. The research method used is purposive sampling and analyzed using the approach quantitative descriptive with the Shannon diversity index formula Wiener. Echinoderm samples were calculated using the technique quadratic transects with a plot size of 2 x 2 meters are placed perpendicularly in the direction of 50 meters using a plot of 30 plot. Environmental factors measured are temperature, salinity, degrees acidity (pH) and levels of oxygen (DO). Measurements are taken at each observation station. The results showed 11 species Echinoderms are divided into 2 classes, namely Diadema setosum, Diadema savignyi, Tripneustes gratilla, Strongylocentrotus droebachiensis, Echinocardium flavescens, Clypeaster subdepressus, and Mespilia globulus from the class Echinoidea. Holothuria atra, Holothuria scraba, Euapta godeffroyi and Chiridota rigida from the class Holothuroidea. The diversity index obtained includes medium category with a value of H = 1.696.
