Abstract

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

Abstract

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.

Abstract

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.
