Abstract

Bivalves are a class within molluscs that includes all shells that have a pair of shells. This study aims to describe the diversity of bivalves in the waters of Donggulu village, Kasimbar district, Parigi Moutong district and the types of bivalves obtained can be used as a learning resource in the form of a pocket book. This research was conducted in Ocean Waters in Donggulu Village, Kasimbar District, Parigi Moutong Regency in February 2020. This type of research is descriptive, sampling using cruising techniques by dividing stations into three stations. The results of the research and identification found 15 types of bivalves, namely Anodonta anatina, Spondylus gaederopus, Macoma balthica, Macoma elimata, Anadara granusa, Anadara gubernaculum, Anadara sativa, Anadara sp, Vasticardium flavum, Donax faba, Hippopus hippopus, Tridacna maxsima, Paphia gallus, Gafrarium sp, and Gafrarium pectinatum. The diversity index obtained is H '= 1.088 which indicates that the bivalve species are at a moderate level. The validation of research results as a learning resource in the form of a pocket book yielded a percentage89.675% which indicates that it is feasible to be used as a learning resource

Abstract

This study aims to describe the effect of the Problem Solving Learning Model based on audiovisual media on the learning outcomes of class XI students at SMA Negeri 4 Palu. This type of research was quasi-experimental with a pretest-posttest control group design. The study was conducted using two groups, namely Class XI IPA 4, which consisted of 31 students as the experimental class, and class XI IPA 3, which consisted of 35 students as the control class. Pretest data in the experimental class obtained an average value of 35.3 and in the control class 34.4. The results of this study obtained the average value of the experimental class learning outcomes that is 73.27 and 67.65 control class. Testing the research hypothesis using the SPSS T-test application. The results showed a significant level value of 0.000 <0.05 or tcount ttable = 6.805 1.997 which means H0 is rejected and H1 is accepted, so it can be concluded that there is an effect of the Problem Solving Learning Model based on audiovisual media on the Learning Outcomes of Class XI students at SMA Negeri 4 Palu

Abstract

Knowledge of behavior is very important to maintain the habitat of the maleo as an endemic animal to Sulawesi that must be preserved. Research takes place in March-December 2021. The research location is in the Saluki Lore Lindu National Park, Central Sulawesi Province. The study took place in March-December 2021. The findings targeted in the study are: (1) Information on egg-laying behavior, (2). When laying eggs, (3) After laying eggs, (4) Determining the length of time for laying eggs, (5) Physical characteristics of the nest and vegetation. The research method used the survey method. Observations of maleo bird activity were carried out every day for 3 months in the egg-laying season from May to July. The results showed that the physical condition of the average nest depth was 67.78 cm, the average nest width was 52.78 cm, the average nest temperature was 33.44°C, the nest humidity was 76.11% and, the soil acidity (pH) with an average of 6.35. The vegetation found at the nesting site consisted of 18 species. The maleo maleo bird's egg-laying behavior activities are playing, snooping (observation), and making a trick hole. There were four activities of female maleo bird laying behavior, namely playing, digging holes for laying eggs, lurking, making trick holes and laying eggs. The duration of time needed by male maleo birds when playing, snooping, making holes, until the female finishes laying eggs, which takes 92 minutes. While the female takes 84 minutes.
