ABSTRACT Seagrass beds are one of the ecosystems that support a variety of life in the sea. Various types of biota live around seagrass beds, one of which is Echinodermata. Echinodermata has a role as a detritus eater in seagrass plants. The association of Echinodermata and seagrass species can be used to see the suitability of a habitat for the existence of species that live in seagrass ecosystems. The purpose of this study was to determine the associations of Echinoderms and Seagrasses on Ra'as Island, Brakas Village, Telangoh Tengah Hamlet, Sumenep Regency, East Java. This research was conducted in November-December 2018. The method used is the quadratic method placed on the transect line with the size of each quadrant of 1x1 m. The association of Echinodermata and Seagrass relationships between Echinoderms and Seagrasses was analyzed by simple linear regression. The results showed that there were 4 species of Echinoderms and 3 species of seagrass. Diversity, uniformity and dominance of Echinoderms at each is low. The association of Echinoderms and Seagrasses showed that seagrass results and Echinodermata did not have a significant relationship. The influencing factor is that most Echinoderms found are Echinoderms, which occupy coral reef ecosystems such as Diadema sitosum, which is most often found at each station.

Human activity recognition (HAR) with daily activities have become leading problems in human physical analysis. HAR with wide application in several areas of human physical analysis were increased along with several machine learning methods. This topic such as fall detection, medical rehabilitation or other smart appliance in physical analysis application has increase degree of life. Smart wearable devices with inertial sensor accelerometer and gyroscope were popular sensor for physical analysis. The previous research used this sensor with a various position in the human body part. Activities can classify in three class, static activity (SA), transition activity (TA), and dynamic activity (DA). Activity from complexity in activities can be separated in low and high complexity based on daily activity. Daily activity pattern has the same shape and patterns with gathering sensor. Dataset used in this paper have acquired from 30 volunteers. Seven basic machine learning algorithm Logistic Regression, Support Vector Machine, Decision Tree, Random Forest, Gradient Boosted and K-Nearest Neighbor. Confusion activities were solved with a simple linear method. The purposed method Logistic Regression achieves 98% accuracy same as SVM with linear kernel, with same result hyperparameter tuning for both methods have the same accuracy.

ABSTRACTIncreased sea surface temperatures due to global warming that occurred from the early to mid 2016 caused of coral bleaching in several locations in TWP Gili Matra. Observations of coral bleaching obtained from coral colonies compotition affected by bleaching (50%), white (18%), death (1%) and was not affected (31%). These implications resulting decline in coral cover but not significant (F (1,013) = 0.333, p > 0.05) from 23,43% ± 2,61 SE in 2012 to 18,48% ± 4,14 SE in 2016 and a significant decrease (P (58,06) = 3,8e-06) recruitment of coral (coral Juvenil) from 6,66 ind.m-1 ± 1,04 SE in 2012 to 1,41 ind.m-1 ± 0,16 SE in 2016. the other impact is a significant reduction (P(20.84) = 0,00053, p <0,001) the abundance of reef fish from 28.733,26 ind.ha-1 ± 3.757,89 SE in 2012 to 11.431,18 ind.ha-1 ± 702,53 SE in 2016 and a decline in the biomass of reef fish but not significant (F (0,58) = 0,46, P> 0.05) from 506,56 kg.ha-1 ± 99,05 SE in 2012 to 438,41 kg.ha-1 ± 45,69 SE in 2016. The decline of coral recruitment resulted in the recovery of the affected areas bleaching becomes slow because of the juvenile new coral mostly dead. The second impact of bleaching is an abundance of fish decrease, indicating that is available only fish big size (adult) and very less of small fishes, including juvenile.

People encounter many changes in the first year of college. It was related to adjustment’s problems, which was a serious problem that must be faced when entered college. Adaptation to new environment can make individual experienced stress. The various studies have shown that medical students experienced stress more higher than non-medical program students. Students who are experiencing extreme stress or depressed require serious attention cause it can have an adverse effect on learning process, achievement and even intent to suicide. This research involved 49 medical students. It took to determine the correlation between level of adjustment to academic demands and stress degree on new students in Faculty of Medicine, Islamic University of North Sumatra, T.A 2016-2017. Student Adaptation to College Questionnaire (SACQ) and Kessler Psychological Distress Scale (K10 Test) were used to collect relevant data on adjustment rates and stress levels. Data were analyzed by using Spearman correlation test. The results showed that there was a significant negative correlation between adjustment rates to academic demands with stress level on new students with p value of 0.001 (p <0.05) and r value of -0.697.

Many people expect a good, healthy, prosperous life, do not experience suffering. People who have a prosperous, healthy life, without suffering are usually identified with people who are obedient and fear God, where the concept of fearing God gets blessings and does not get curses, suffering, or other bad things that are often referred to as the principle of retaliation. This principle of retaliation is a common and believed principle from time to time. In wisdom literature, the principle of retaliation is one of the points that need attention. But in fact there are many who are pious, fearing God, whether they experience suffering that is not appropriate. This research approach is qualitative using a theological approach that can be used to understand the gaps that occur, collect data from various literary sources that can be used to collect the material needed, such as books in libraries, Junarl, the web, electronic mass media, etc. . the concept of the principle of retribution cannot be established in general terms and can be stated inaccurately if it is addressed to righteous people, pious people, good people, and suffering children, because the theory stated by the facts that occurs is incompatible and very contradictory.

Indonesia, as the country with the world’s largest Muslim population, has issued a regulation on halal product assurance (UU JPH) Act No. 33/2014. Furthermore, the consumers’ care on the halal food is another significant element in the implementation of this regulation. This study concerns on how the students of Islamic Senior High School (MA) in Surakarta care on the halal food products. This is a quantitative study in which data were collected using questioners. There are 430 selected students participated in this study. Data was analyzed using descriptive analysis by counting the mean score and classified into four categories namely; do not care, less care, quite care, and care. Findings of this research showed that most students are “quite care” for halal product, but they mostly did not ask to the merchants whether the product they bought to have “haram” ingredients or not. Moreover, the majority of students sometimes checked the halal label on the product, while others did not check them at all. Overall, the students’ care level toward halal product is categorized as at the “quite care”. This result indicated that it needs more concern from the related stakeholders on how the students can be more attentive toward halal food products.

[English]: This study examined the effect of Problem-based Learning (PBL) on students' creative mathematical thinking in Indonesia during the last eight years using meta-analysis. Data were obtained from primary studies published in national journals, conference proceedings, and master thesis from 2012 to 2020. This study analyzed 19 effect sizes from 19 primary studies that fulfill the inclusion criteria. The effect size index used the Hedges' g equation and statistical analysis was assisted by comprehensive meta-analysis (CMA) software. The effect size variation test was conducted by analyzing the study's five characteristics, namely the year of study, level of education, sample size, length of treatment, and publication sources. Based on the analysis results, the overall effect size was 0.821, with a standard error of 0.130 at the 95% confidence interval (CI) referring to the random-effects model. The effect size is classified as moderate, meaning that PBL has a moderately positive effect on students' creative mathematical thinking. The results of the analysis of the characteristics of the study show that the application of PBL to improve students' mathematical creative thinking relates to the research year (Q = 55.683; p <0.05), the treatment duration (Q = 5.644; p <0.05), and publication sources (Q = 13.812; p <0.05). It was found that the PBL was more effective in conditions of treatment duration of fewer than four meetings. There is a tendency that PBL has a significant impact when it is first implemented. The findings' implications are discussed to provide important information as a basic idea for further PBL research and implementation.

Gunung Palung National Park were protected since 1937 and become remain conserve largest dipterocarp forest in Borneo. The park has severe forest loss caused by anthropogenic activities and forest fire. To help inform conservation efforts about pattern and distribution of deforestation in the park, we measured forest cover change in the protected area using 11 multi-temporal Landsat series images with path/row 121/61. We found the park already loss 10.68% of its forest area in 1989 and 26% from an initial loss in 1989 in 1997 caused by El Niño event. Currently, deforestation rate is 0.21%, higher than global rate cause El Niño of 2015/16 event and make severe forest fire. The direct impact of deforestation and or degradation in a protected area is biodiversity loss and shortage water storage or flooding. This biodiversity loss created by habitat loss, fragmentation, or genetic drifting. Different wildlife and vegetation have a different response for habitat change and will reach the new equilibrium.
