Abstract

The PjBL approach is applied to the Physics Laboratory Management course to support the achievement of learning outcomes. Through PjBL, preservice teachers are given assignments related to their future work as teachers and are required to complete them in groups. This study aims to determine how preservice teachers perceive their collaborative skills while interacting with group members when completing assignments. This research applied a mixed-methods approach to better understand research problems by quantitative and qualitative data. We employ total population sampling to examine the entire population with a particular set of characteristics from 67 people who completed the group project assignment. We analyze and describe the quantitative and qualitative data results to answer preservice teachers' perceptions of their collaborative team working skills during PjBL. We prefer the explanatory design method, where qualitative data is needed to explain the significant quantitative results. As a result, Preservice Teachers' perception shows that during PjBL, they have obtained collaboration skills in teamwork, managing conflicts, decision making, and communication skills. From the interviews, we dig up additional information about their complaints about the difficulty of completing projects and working in teams. However, the benefits of the additional skills they get are more profitable than their challenges. This analysis informs us that Preservice Teachers show a more significant positive response regarding collaboration skills during PjBL. It can be considered to continue to bring up collaboration skills in any given learning approach.

Abstract

Obesity problems in children will be at high risk of obesity in adulthood and potentially experience various causes of significant risks for some chronic diseases associated with diets, such as type 2 diabetes mellitus, hypertension, stroke, cardiovascular disease, and certain types of cancer.This research aims to determine the effect of health education based on social media to the pattern of physical activity and body mass index (BMI) adolescent overweight and obesity of each group and between groups in Bulukumba, Indonesia. The design of this research is the "Quasi Experiment," which is a pretest and post-test wa ith control group design. The population in this study were overweight and obese adolescents in Bulukumba Regency. The number of samples is 91 people divided into 4 (four) groups. The analysis used is the Friedman test, Kruskal Wallis, repeated ANOVA, and one-way ANOVA. The intervention was given for six months through health education with a lecture media booklet in groups 1 and 2, leaflets in group 3, and lecture method alone without media in group 4. In groups 1 and 2, we were given re-education through the WhatsApp application in group 1 and through messages in group 2. Periodic time series measurements were taken for six months on the variables of physical activity pattern and BMI. The results showed an effect of health education on the changing of activity patterns in each and between groups. There is an effect of health education on BMI changes in groups of 1,2 and 3 and between groups, but there is no influence on group 4. This study recommends to health workers (nurses, nutritionists, and health promotion) the use of booklets and utilizing social media (WhatsApp) in providing health education related to obesity.

Abstract

Slow growth rate tends to be a challenge in the cultivation of spiny lobster (P. homarus) because it impact on long rearing periods and high operational costs, especially for feeds. Short-term starvation or fasting has known to allow the minimum feed usage without inhibiting biota growth, also improves digestive function, reduces the amount of water-soluble nutrient metabolites, and reduces operational costs. Spiny lobster (P. homarus) measuring 50.0 ± 10.0 g was reared for 6 weeks in floating net cages. Lobsters were fasted at intervals of 1 fasting day/1 day of feeding, 1 fasting day/2 days of feeding, and fed daily. Survival, growth, and feed efficiency of spiny lobster (P. homarus) were analyzed. Higher growth rate and energy retention were found in spiny lobster (P. homarus) reared with short-term fasting system.  Lower FCR also found in the same rearing system. Spiny lobster (P. homarus) body content indicate its ability to store nutrient in mucle and hepatopancreas in order to adapt to starved condition. Short-term fasting can improve growth and feed efficiency in spiny lobster (P. homarus) cultivation

Abstract

Porang (Amorphophallus muelleri) is a tuber plant that contains a lot of glucomannan fiber. Glucomannan is a soluble fiber that can form a gel that mimics the characteristics of fat so that it has the potential to be used as a fat replacer in high-fat products such as cookies. The purpose of this study was to determine the effect of using fat replacer on the sensory acceptability and characteristics of cookies. The steps carried out in this study were to determine the concentration of porang flour in fat replacer (5 and 7.5%). Fat replacer with firmness that is closest to margarine at a concentration of 5%. Furthermore, cookies were made with fat replacer substitution (25, 50, and 75%). The cookies were then tested for their organoleptic properties using the hedonic method on the parameters of color, aroma, taste and texture. The best cookie formulation was obtained at 25% substitution, which was then compared with the control formulation by testing the parameters of proximate, crude fiber, texture, and oxalate content. The results showed that cookies with fat replacer had lower levels of ash, fat, protein, calories, and hardness than the control, although the difference in fiber and protein content was not significant.

Abstract

Until now, conflicts between elephants and the community are still occurring, one of which is in the Bukit Barisan Selatan National Park. This conflict has a negative impact on both elephants and society, so it is necessary to examine the habitat factors that determine the movement of Sumatran elephants. Therefore, the aim of this study is to determine the daily movement of the elephants and to analyze the habitat factors that influence elephant movement. Data was collected in the form of elephant movements in one period which were obtained from the Bukit Barisan Selatan National Park. 1-year results obtained from the GPS stated that there are two groups of elephants, the citra elephant group and the bunga elephant group. The results showed that groups of elephants in Bukit Barisan Selatan National Park have lengths that ranged from 63 – 137 kilometers, with linear, zigzag and circular trajectories, and the frequency of points used is 2-6 repetitions with the time needed per-kilometers ranging from 110 – 518 minutes. Factors that influence elephant movement are track length, frequency of point used, time spent per-kilometers, altitude, slope, distance to settlements, distance to water sources, availability of feed, and availability of scrubbing trees
