Abstract

Research has been carried out on the physical properties and compressive strength of karst rocks in the Leang Londrong cave area. The purpose of this research was to analyzr the value of physical properties and compressive strength of rocks including density and porosity and also calssify limestone types based on the value of physical properties and compressive strength. The compressive strength value obtained from a non-destructive method, namely by using a Schmidt Hammer. The process starts from taking 30 rock samples in the Leang Lonrong cave area at 10 predetermined points. Based on the physical properties test of karst rocks in the Leang Londrong cave area, the rock density values are in the range of 2,60  to 2,62 , while the porosity value are in the range 0-6 %. So that the type of rock in the Leang Londrong cave area is dolomite limestone. The compressive strength value of the rock is obtained from the conversion of the Schmidt Hammer rebound value. The value of the compressive strength of karst rocks is obtained in the range of values fro, 20 MPa to 62 MPa. So that the rocks in the Leang Londrong cave area are quite hard or medium types of rock.

Abstract

This study aims to determine how the implementation of various integrations of religious and scientific knowledge in learning activities in Indonesia with the concept of wahdatul 'ulum. Through the search for articles with keywords that match the objectives, 35 articles have been obtained that have concretely carried out research with various wahdatul 'ulum designs. The literature obtained was then analyzed and mapped with NVivo 12 based on the integration process and its implementation in learning activities. The results obtained are that most of the literature adopts the values of Islamic teachings originating from the Qur'an (57%), compared to the adoption of scientific concepts that are in line with the ayah of the Qur'an (43%). In the implementation of learning activities mapped into media, models, and learning assessments. It was found that the development of learning media in the form of modules that applied the concept of wahdatul 'ulum became the most dominating (18 articles). The findings of this study become a discourse for educators to continue to strive to implement wahdatul 'ulum in various components of learning so that there is no longer a dichotomy between religion and science because, in fact, various kinds of knowledge originate from Allah SWT with no contradictions in them

Abstract

Plant roots have an important role in plant growth. Roots function as absorbers of water and other nutrients in the soil which are distributed to other body organs. Distribution patterns, root growth and root range influence plant growth and development. Vertisols are one of the dominant soil orders in southern Lombok, but their physical characteristics are rich in monmorillonite type clay which expands when wet and shrinks when dry. This study aims to analyze the pattern of root distribution through the root growth rate of the three chili varieties and to analyze the tolerance level of the three chili varieties. The field experiment was organized according to a Randomized Completely Block Design with three replications. The varieties of chili plants planted are Kara chilies, Dewata chilies and local chilies. Root growth rate was measured on serial plant samples observed every 20-day interval until day 60, during the growth period. The results obtained showed that the distribution patterns of the three varieties experienced an increasing trend in the rate of root growth, for the kara varieties it reached a figure of 4.65 cm, for local varieties is 5.54 cm; and in the dewata variety it is 2.67 cm. The tolerance level of chili plants to congested conditions was seen from the results of their root growth rates, the three varieties showed that they were Semi Tolerant (ST) to waterlogged environmental conditions on vertisol soils.

Abstract

Indigenous communities have long had an unwritten norm system that regulates the protection of forests and biodiversity inside. The principle of traditional conservation on the island of Sumatra for the preservation of Sumatran tigers is to implement environmental management in the form of prohibitions or invitations in forest areas. On the other hand, this cultural concept is intertwined with learning. Students can discuss lesson concepts in a cultural perspective to support meaningful learning in biology lessons. Therefore, the purpose of this study is to find out the values of traditional conservation of the Sumatran tiger which can be used as a source of developing biology teaching materials based on cultural perspective. The method used in this research is a literature review and content analysis. Researchers searched works of literature from multiple data search engines, namely PubMed, Google Scholar, Mendeley, Semantic Scholar and the Publish or Perish. Data is processed and analyzed according to research needs. Based on the results of the study, obtained results regarding the identification of Sumatran tiger, threats, and forms of conservation in the natural habitat of the Sumatran tiger. Based on the Curriculum 2013, the relevance of this study is linked to the biology material on biodiversity in basic competencies 3.2 and 4.2 regarding distribution, threat analysis, and conservation efforts of biodiversity for the grade of 10-th of high school.  The material is also included in the learning outcomes of the Merdeka Curriculum phase E for class x regarding understanding and process skills analyzing interactions between ecosystem components and efforts to conserve biodiversity. These material resources can be developed into a module-based on local culture to be studied independently by students.
