Abstract

The effectiveness of soil microarthropods as a bioindicator was studied to evaluate various soils in the conditions of various lands, including moorland in Gumukmas District, Jember Regency. This study focuses on data collection of the diversity and structure of soil microarthropod communities along with the assessment of their ecological parameters. Field observations were carried out in five villages in Gumukmas District from August-September 2022 using the hand sorting method.  The data were analyzed using α-diversity parameters (Dominance Index, Simpson Index, Evenness, Shannon-Weiner Index, Brillouin Index, and Margalef Species Richness). Habitat similarities were presented by UPGMA multivariate analysis and the estimation of abiotic factors that influence soil microarthropod composition was estimated by Canonical Component Analysis (CCA). The observations showed a total of 24 families from 13 soil microarthropod orders that spread across Gumukmas District. The abundance of diversity based on the α-diversity is still relatively low to moderate, nevertheless, the correlation of microarthropod orders to environmental factors can reveal conditions of the soil cycle through the study site. The results of the study are expected to assist in efforts to restore the diversity of soil microarthropods to support better soil quality.

Abstract

Soil insects live in the soil or even both on the surface of the soil. Soil surface insects are one of the important animals in the soil ecosystem because their role is very important in the survival of the vegetation above them. Soil insects act as decomposers of organic materials, which will be useful as nutrients for plants. Apart from that, soil insects can also be used as indicators of soil fertility. The aim of this research is to determine the diversity of soil insects in the rice field ecosystem of Palembang City. This research was conducted in a rice field ecosystem using the pitfall trap method, 4 traps for 30 days. The results of the research obtained 14 species of soil insects from 11 families and the diversity index level of soil insects was classified as medium with a diversity index value of 1.057 with the dominating species, namely Camponotus laevigatus (Hymenoptera: Formicidae). Soil insects are an important part of an ecosystem or habitat. The diversity of ground surface insects and ecosystem functions show a very complex relationship and not much is known with certainty. A decrease in diversity and changes in the role of ground surface insects will occur due to changes in land use systems and habitats that are degraded due to development. The level of soil insect diversity needs to be maintained or increased to ensure soil fertility and overall ecosystem health and function remain optimal.

Abstract

This study aims to produce a product in the form of a practical work guidebook for making nata de coco to help smooth the practical work process, which was adapted from the development of a 4-D model. The 4-D model consists of 4 stages, namely the stage of defining, designing, developing and disseminating. The level of feasibility of the practical work guidebook is carried out through a validation process by material experts, media experts and supported by responses from teachers and students. The results of the validation carried out by material expert validators and media experts were categorized as "Very Eligible" with 95% and 92.85% respectively. Meanwhile, the teacher's response and the student's response were also categorized as "Good" with 95% and 99% respectively. This is supported by the effectiveness test conducted in the cognitive (pretest and posttest) and psychomotor domains. In the cognitive domain, it shows a fairly good score, which has a difference between the initial ability (pretest) and the final ability (posttest) with an average value of 46.32 to 78.12. The t test also shows a significant value of 0.000 with the "medium" N-Gain category (60.6%). The psychomotor domain also produced a score with an average of 82 of the overall score or the “Excellent” category. Based on the research data, it can be interpreted that the book developed has a considerable influence on practical learning outcomes and can facilitate students to learn, both with educators and independently in making nata de coco which is packaged in an attractive and easy to understand manner.

Abstract

Students are demanded by school assignments, and many of them feel under pressure when learning biology. This situation is a trigger for academic stress which has an impact on student achievement. This study aims to identify and compare the factors that influence academic stress on students studying biology at the senior high school level. The research method used was an ex post facto survey using a sample of 54 students with an age range between 16-18 years. Data were obtained through a questionnaire with 9 scales of answer choices and interviews. The results showed that the level of preference for biology subjects for both public and private high school students was quite good, but most students experienced academic stress with a fairly high category in terms of motivation, self-confidence, the education system, teachers, and school conditions. This research implies that teachers are expected to create learning strategies by paying attention to the psychological conditions of students so that student learning outcomes can be maximized.
