Yulian Pratiwi Pratiwi — 2021-08-29

This study aims to develop learning media in the form of magazines resulting from the morphological characterization of the Keprok Terigas citrus plant and to determine the level of feasibility. This type of research is research and development (R&D), with the first phase of qualitative research aiming to determine the morphological characterization of the Terigas Tangerine plant (Citrus reticulata Blanco). Data collection using observation and documentation methods. The second stage is the development of the magazine learning media product using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). This research was only carried out until the implementation stage. The results of the first stage of research, namely the morphological characterization of citrus plants with tree stature and dark brown taproots. The stem is cylindrical in shape, the direction of growth is straight (slightly bent on top), the texture is strong and sturdy, and the color is brownish green. The leaves are compound, oval-shaped elongated, the base of the leaves is blunt, the tips of the leaves are pointed, the edges of the leaves are serrated, the upper surface is shiny, and the lower surface is rough, and the leaves are green. The flowers include compound flowers with a complete arrangement of yellowish white, and have two sexes, namely stamens and pistils. The flowers on this plant have the formula (♀*K5, C5, A16, G1). The fruit is a single true fruit that is fleshy, round and greenish yellow in color, and the seeds are oval-shaped yellowish white. The results of the second stage, namely research on the morphological characterization of the Terigas Tangerine plant (Citrus reticulata Blanco) was developed as a magazine, and validated by material experts, media experts and lecturers in Plant Anatomy and Morphology courses, each obtained a percentage of 76.4% (decent), 95% (very decent), and 85.2% (very decent). The results of the student legibility test on the feasibility of the magazine learning media obtained an average percentage score of 91.5%, which stated that this magazine was suitable to be used as one of the learning media to study Plant Anatomy and Morphology courses.

The effectiveness of oshibana book development for class VII students of MTs Darissulaimaniyyah plant classification materials

Azzahra Siwi Hesti Manekung — 2021-08-29

This study aims to determine the effectiveness of the Oshibana book in science learning for seventh grade students of MTs Darissulaimaniyyah Plant Classification material. The research method used in this study is Research and Development (RnD) using the ADDIE model, which consists of five stages: Analyze, Design, Development, Implementaion and Evaluation. The effectiveness of the Oshibana book was measured through a feasibility test, a readability questionnaire and a trial to students using pre-test and post-test questions. The feasibility test for the Oshibana book was carried out by three validators, namely material expert validators, media expert validators and seventh grade science teachers at MTs Darissulaimaniyyah. The product trial design for students uses Quasy Experiment using amodel non equivalent control group design. The sample used was class VII B as the control class and class VII C as the experimental class, the sample was determined by purposive sampling technique.

Oshibana book development process which includes special needs analysis, curriculum analysis and preparation of Oshibana book design. The results of the special needs analysis showed that 53.06% of the seventh grade students of MTs Darissulaimaniyyah did not have special learning media to study Plant Classification material so that researchers tried to develop the Oshibana book, as many as 81.63% of students agreed that the Oshibana book was developed as a learning medium. The results of the curriculum analysis of Plant Classification materials are studied in KD 3.2 about classifying living things and objects based on observed characteristics, and KD 4.2 about presenting results on classifying living things and objects around based on observed characteristics. The process of compiling the Oshibana book consists of several components, namely: cover front, introduction, table of contents, list of pictures, learning outcomes, book contents (Plant Classification materials and Oshibana materials), assignments, how to use and care for Oshibana learning media, reference lists and cover back.

The results of the Oshibana book feasibility test by material experts obtained results of 72% with the criteria of being effective as a learning medium, the results of the assessment of media experts obtaining results of 81.67 with the criteria of being effective as a learning medium and the results of the assessment of the seventh grade science teacher obtaining results of 92% with the criteria very effective as a learning medium. The results of the readability test by students of MTs Darissulaimaniyyah obtained an average of 88.01% with the criteria of being very effective as a learning medium. While the results of the trial to the experimental class and control class students obtained a comparison of the average N-gain value of 0.6667 0.0185 which indicates that the average N-gain value in the experimental class using the Oshibana book is higher than the control class. who didn't use Oshibana's book. The test of the effectiveness of the Oshibana book was carried out using the Independent Sample Test, the results obtained were 0.00 0.05 indicating a significant difference. The results show that Oshibana's book is effective as a learning medium for studying Plant Classification materials.

The fingerprint patterns Sumba ethnic population in Tambolaka City, East Nusa Tenggara

Nila Kartika Sari — 2021-06-28

One of the biological features that humans have is fingerprints. Genetic factors have a role in the formation of fingerprint patterns. In general there are three patterns in the fingerprint that is loop, arch and whorl. The purpose of this research is to know the pattern of fingerprints on Sumba ethnic population in Tambolaka city, East Nusa Tenggara. This research uses qualitative descriptive method because it aims to know the pattern of sidik on Sumba ethnic population. Data collection was done by using documentation, interviews and giving respondents. The research benefits provide information on the pattern of fingerprints on the Sumbanese ethnic population based on the shape of the fingerprint. The sample consists of 56 people. Overall of the patterns contained in the ten fingers of Sumba samples were mostly found in loop patterns with a percentage of 54.41%, whorl patterns 43.97%, and arch patterns of 1.62%. Based on the results of research on the pattern of fingerprints on Sumba ethnic population in Tambolaka the most dominant fingerprint pattern is to have the pattern with the highest order of loops seen on the left thumb, left middle finger and little finger, whorl pattern where this pattern is the highest pattern Second after loop and the third is the arch pattern.

The relationship between the air temperature change daily, farmer behavior, and diversity pollinating insects in the district of Bumijawa Tegal Central Java

Dwi Yuliani — 2021-08-29

Global warming has threatened Indonesian’s agricultural sector and set the sector vulnerable to climate change. The changes affect the daily air temperature changes, farmer behavior, and the diversity of insect pollinators. The study aims to determine the daily changes in air temperature, farmer behavior, and diversity of pollinating insects in the Bumijawa, Tegal, Central Java; and to analyze the relationship between daily air temperature changes, farmer behavior, and insect pollinators diversity. The research employed survey methods. Samples for the daily air temperature measurement were taken purposeviley. The diversity of insect pollinators on the three farming type and respondens were selected radmonly with total respondent 99. The results showed that the average daily air temperature in chili farms is higher than that in tomato and strawberry farm; farmers have a good knowledge about the environmental degradation of agriculture land, good attitude and awareness in maintaining and improving the quality of agriculture, but they have negative behaviour in the use of excessive doses of fertilizer. Species richness of insect pollinators in tomato farm is higher than that in chili and strawberry farm. A good knowledge, good attitude, and bad behaviour are closely related to the daily air temperature and insect pollinators.
