The Coastal Area is an aquatic ecosystem that has high productivity and is able to support the survival of various aquatic biota and is often used as a place for various daily life activities by residents including fishing activities, tourism activities and mining activities. The aims of this study were to analyze the density, diversity, uniformity and dominance of molluscs (gastropods and bivalves) and to analyze the relationship between the density of mollusks (gastropods and bivalves) and environmental factors. The sampling technique used the 1x1m² Quadratic Transect method. The results obtained at all observation stations were 13 types of gastropods and 9 types of bivalves. Diversity is in the low to medium category which ranges from 0.8760 to 2.1655. The uniformity of gastropods and bivalves was moderate to high which ranged from 0.5291-0.8715, and was dominated by Pinerella cingulata gastropods. The results of principal component analysis (PCA) showed that the density of gastropods showed the parameters of depth, silt and clay, and the density of bivalves showed the parameters of brightness, salinity and sand which had a high affinity with density which was a limiting factor for the distribution or abundance of gastropods and bivalves.

Group cohesiveness is usually an interesting object of study in the context of social life and work management. However, cohesiveness can also be found in educational study areas. This study aims to determine the cohesiveness of the students of SD Negeri 2 Prambanan, find out the differences in cohesiveness between the independent groups and teacher formation groups, and the impact of the cohesiveness on the learning strategies. The quantitative methods are used to measure and to compare cohesiveness between the two groups using a t-test. The qualitative methods are used to narrate how teachers implement learning strategies according to student cohesiveness. The cohesiveness refers to the concept of Forsyth, which divides into the social, task, perceived, and emotional. This study finds that first, the group cohesiveness of students is in a moderate position. Second, the independent groups have significantly higher than the teacher formation groups. Third, there are five follow-ups in learning strategies undertaken by the teacher, i.e. rearranging student seats, making students who have high group cohesiveness as group leaders, motivating students who have low cohesiveness to be actively involved in their groups, giving freedom to groups to compete, and applying various collaborative

The study of Islamic education theory has so far prioritized the thinking of educational scholars from the Arab world. However, the study of Islamic educational thought of Nusantara scholars still needs to be encouraged. One of the Nusantara scholars who was very instrumental in the Indonesian Islamic intellectualism tradition was Sheikh Abd Shamad al-Palimbani (1704-1789). This article aims to explain al-Palimbani's educational thoughts, especially on the ethical aspects of a student and teacher, as well as its relevance to the educational practices today. The main data source of this article is al-Palimbani's work entitled Sair as-Salikin. The content analysis is used to analyze and explain the work. This article finds that in al-Palimbani's view, a student must have ethics both relating to himself and relating to his teacher. Some of the ethics are a student must be clean of his heart from despicable nature, focus on study, redempted, respect knowledge, intention because of God, respect the teacher, and not feel smarter than his teacher. Meanwhile, a teacher should be patient, affectionate with students, humble, accept the truth of other opinions, not expect rewards, resuscitate students and others. It some points of al-Palimbani's educational thought that are still very relevant to the characteristics of 21st century education. Among them are the importance of mutual respect between students and teachers, honesty in communicating, openness in accepting the truth, and lifelong learning. At least, al-Palimbani's educational thougths are relevant to the characteristics of 21st century education, in expecting rewards from teaching activities and excessive restrictions on students when in the presence of teachers
