This research aims at investigating the effect of Complex Instruction integrated with Team Product (CITP) learning model on students' creative thinking skills, critical thinking skills, metacognitive skills, scientific attitudes, cognitive learning results, and retention. This research used quasi-experimental design with pretestposttest nonequivalent control group design. This research was carried out in several Senior High Schools in Ambon, namely SMA 1 Ambon, SMA 4 Ambon, SMA 5 Ambon, SMA 13 Ambon, and SMA Kristen Ambon in the even semester of the academic year 2017/2018. The results of the research were analyzed using ANCOVA. A post hoc LSD test was also performed if there were differences in each variable. The results of the research show that the CITP learning model affects creative thinking skills, critical thinking skills, metacognitive skills, scientific attitudes, cognitive learning results, and retention of class X senior high school students on Ecosystem learning material. The syntax of the CITP learning model can improve students' creative thinking skills, critical thinking skills, metacognitive skills, scientific attitudes, cognitive learning results, and retention compared to the learning model commonly implemented by the biology teachers.

Forests provide protection, food, and habitats for wild animals such as monkeys, birds, bats, squirrels, and weasels that depend on the fruits and seeds from the trees. Due to human’s activities, the functions of the forest in Bacan Island have decreased significantly in terms of numbers, kinds, and important value index. Local people have conversed forests into agricultural lands. As a result, the existence of natural resources especially trees, which supply nutrients for wild animals such as monkeys, birds, bats, squirrels and weasels, is being threatened. The current study aimed to investigate the composition and important value index of every type of plants used for wildlife feed. An inventory method was employed in plots of 20 m × 20 m for tree-level observation. This method would be useful to obtain the list of plant composition for wildlife feed and to determine some vegetation parameters including the density, domination, frequency, and important value index of the plants. This research showed that Duobanga moluccana, Drancontomelon dao, Bacacaurea anguilata Merr, Theobroma cacao, Mangifera indica, Canarium casferum, Myristica fatua and Myristica sperciosa are the composition of plants that could supply nutrients for the wild animals. The highest important value index (IVI) (52.78%) was observed in Drancontomelon dao. Medium IVI which ranged from (31.47-44.42%) was reported by Duobanga moluccana, Bacacaurea anguilata Merr, Theobroma cacao, Canarium casferum, Myristica fatua and Myristica sperciosa. Meanwhile, the lowest IVI (29.52%) was found in Mangifera indica.

Sia-sia (Sipunculus nudus) has a shape resembling a worm, is an organism that usually lives in coastal areas, especially around seagrass areas, this biota tends to inhabit the bottom of the water especially in the substrate so that it is categorized as an infauna benthic organism and is able to inhabit areas with soft and hard substrates. This is a deskriptive type of research, to describe or describe information about the density and morphometrics of Sia-sia  from the coastal waters of Nusalaut Island, Central Maluku. The results of the study on the density of Sia-sia on the island of Nusalaut, differ according to location, based on the results of the density calculation obtained. Each location shows the total average value of Absolute Density (KA) is 0,0063 ind/m2 (Low) and Relative Density (KR) is 100%. The Absolute density level (KA) in Abubu Vilage is 0,0068 ind/m2 (Low), the absolute density level (KA) in Ameth Villlage is 0,0064 ind/m2 (Low) and the absolute density level  (KA) in Akoon Village is 0,0058 ind/m2 (Low), Based on the results of the Sia-sia morphometric research from Nusalaut Island, the Results vary from each village with Sia-sia morphometric average length of 12,14 cm, width 2,15 cm and weight of 31,6 g, followed by Akoon village with Sia-sia morphometric average length of 11.6 cm, width 2,21 cm, and a weight of 33,6 g, and the last one is Ameth Village with an average length of Sia-sia morphometric that is 13,02 cm, width 2,26 cm, and weight 36 g

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

Abstract. One of the ecological roles of seagrass beds is as fish habitat and the presence of seagrasses can affect the diversity and density of fish in a water. Distribution of seagrass vegetation in the waters of the village of Akoon is quite extensive with conditions that are also quite diverse, allowing the many types of fish that live in the seagrass beds in the village of Akoon. Nusalaut, Central Maluku Regency. The results of the study describe the types of fish that are in the seagrass beds in the village of Akoon are 17 species with 80 individuals. Fish species diversity index in the seagrass beds in Akoon village, Nusalaut sub-district was 2,434, evenness index was 0.859, and wealth index was 1,900. Fish in seagrass beds in Akoon village, Nusalaut sub-district have a density value of 0.2 ind / m2. Keywords: diversity, density, seagrass fish, Akoon Village
