Educational paradigm thoughts in this 21st century in line with the development of science and technology. We see nowadays that cellular computation program enables lecturer to record students` assessment data directly from mobile device. Besides, by the use of electronical devices that could be operated to increase and enhance students` learning in various way like enhancing students` understanding in theories, related with a performance or presentation, lab and experiments or written task and assignments. Then mobile device termed gadget. To know the influence of gadget learning model usage towards students` learning result and thinking skill in accomplishing assignments on vertebrate zoology course of college students from biology education faculty of education pattimura university. This research being held in Faculty of Education Pattimura University Biology Education, on Ferbuary 10th - June 10th 2019. Data will be analyzed statistically using SPSS 2.0 Key Words: Gadget Learning Model, Thinking Skill, Students` Learning Result

Nutmeg (Myristica fragrans Houtt) is commonly cultivated by people in the forests of Moluccas Islands. This plant grows well on relatively infertile soil types. This is presumably due to the presence of symbiotic microbes in the root of nutmeg. The research aimed to isolate, characterize and test the potential of Actinomycetes from rhizosphere of nutmeg. Soil sample were taken from the nutmeg forest in Ambon Island. The Actinomycetes isolation using humic acid vitamin, continued with yeast malt agar (YMA) media. The testing of antibacterial and antifungal activities using YMA media, while cellulolytic activity, phosphate solubilizing, and xylanolytic activity using carboxyl methyl cellulose, Picovskaya agar, and birchwood agar or oat spelt xylan agar. A total of 12 isolates of Actinomycetes were isolated and dominated by Streptomyces with various types of aerial mycelia. The substrate mycelium looks brown and cream, while the aerial mycelium looks white and gray. These isolates had the highest inhibitory power against Escherichia coli and Fusarium oxysporum with indexes of 16.5 mm and 16.0 mm, respectively. The other isolates have the ability of cellulolytic, phosphate solubilizing, and xylanolytic with indexes 3.26, 3.87, and 1.2, respectively. The Actinomycetes isolates that were found can be used as starter to improve the biofertilizer formula for nutmeg.

Patellidae are gastropods that live in intertidal zones and sublittoral zones of shallow rocky shores because Patellidae are usually attached to boulders. Patellidae belongs to the order Archaeogastropoda and generally only has two genera, namely Cellana and Patella. Patellidae are also found in the waters of Ambon Island, namely in the Hukurila Village and Allang Village. This study aims to determine the type, morphometrics, density, and proximate levels of Patellidae in the waters of Ambon Island. Samples were taken using purposive sampling with cruising methods. The Patellidae are attached to the substrate. Samples from two locations were taken and put into plastic, and then the type and morphometrics were identified at the Basic Biology Laboratory of the Faculty of Teacher Training and Education, Pattimura University. Proximate levels were conducted at the Basic Chemistry Laboratory, Faculty of Mathematics and Natural Sciences, Pattimura University. This research was conducted from October 15, 2022, to November 15, 2022. Based on the results, two species of the Patellidae family were found in Ambon Island, namely C. testudinaria and P. flexuosa. The results of the calculation of morphometric Patellidae in the Waters of Ambon Island showed that the species C. testudinaria in the Waters of Hukurila Village has a larger morphometric characteristic size compared to the species C. testudinaria and P. flexuosa in the Waters of Allang Village. More individuals of P. flexuosa species were found in Alang village than C. testudinaria species, while many C. testudinaria species were found in Hukurila village. Based on the proximate analysis results, Patellidae from the waters of Ambon Island have nutritious and good nutritional content to be used as food ingredients.

Kepadatan Nerita sp Di Perairan Pantai Negeri Suli Teluk Baguala Kabupaten Maluku Tengah Sintje Liline; Muhammad Tarmizi Kubangun; Tri Santi Kurnia; Wa Nurul Mutmainah Jainudin Heremba

Suli in Baguala Bay, Central Maluku Regency has waters with various types of substrates, namely sandy, muddy and rocky which are rich in benthic organisms. One of them is the gastropod type Nerita sp which is widely used by the population for food needs. The existence of gastropods, especially Nerita sp needs to be maintained and preserved so that the diversity and density of Nerita sp can be maintained and well maintained. This study aims to determine the type and density of Nerita sp. In the coastal waters of Suli, Baguala Bay, Central Maluku district. This research is a descriptive study, namely research to reveal information about the density of Nerita sp in the coastal waters of Suli Baguala Bay, Central Maluku district which is presented in the form of tables and numbers and the research was conducted in July 2019. Based on the description of the morphology of Nerita sp. from the land of Suli, including the species Nerita chamaeleon. The total number of Nerita chamaeleon found was 566 individuals with a density value of 11.32 and categorized as having sufficient density. It is necessary to do further research on the nutritional content and its use by the people of Suli. Keywords: Density, Nerita sp, Suli
