Nocturnal insects are a type of insect that is active at night and plays a role in maintaining the balance of the ecosystem and has an ecologically and economically occurring role. This study was conducted to determine the diversity, evenness, and dominance of nocturnal insects based on the color of the light trap lamp at the Vegetable Crop Research Center of Tongkoh Village, Karo Regency, North Sumatra. This study used the light trap method by making a transect 100 m long and on the transect, 5 observation stations were installed. There are 27 insect families consisting of 35 types of nocturnal insects with a total of 240 individuals. The most common type of insect found is Empoasca fabae. The diversity index (H') is included in the moderate category with a value of 2.10 on the green lamp trap, 1.38 on the blue lamp trap, 2.23 on the yellow lamp trap, 2.76 on the white lamp trap, and 2.26 on the red lamp trap, this shows that the insect diversity at the study site is in a stable condition. The dominance index (C) is categorized as low with a value of 0.184 on green light traps, 0.347 on blue lamp traps, 0.222 on yellow light traps, 0.092 on white light traps, and 0.150 on red light traps. This situation occurs because there is no type of nocturnal insect that is too dominant so that the diversity of insects is classified as being in a stable state.

This study aims to determine the effect of using compost and the optimum compost dosage from baglog waste of oyster mushroom (Pleurotus ostreatus) on the yield of mustard greens (Barassica juncea L.). The method in this study used the experimental method. The research design was a single factor Complete Randomized Design (CRD) consisting of 5 trials with 4 replications to obtain 20 trials. The results of this study indicate that the application of compost from oyster mushroom baglog waste showed a significant difference in the measurement parameters of first harvest time, first day of first true leaf emergence, plant height, and planting wet weight. The most optimal dose between soil and compost as a microgreen mustard planting medium is 9.5 kg of soil + 500 grams of compost

Pollinating insects are insects that have an important role as intermediaries for pollinating plants by collecting pollen and nectar found in strawberry flowers (Fragaria sp.). This research was conducted to determine the types of pollinating insects and the diversity of pollinating insects. This research was conducted in Tongkoh Village, Dolat Raya Sub District, Karo District, North Sumatra. Intake of pollinating insects is done by observation method. The results of the study obtained 3 orders and 7 families as well as 11 types of pollinating insects with a total of 147 individuals. The most common type of insect found was Apis cerana. The diversity index of pollinating insects was moderate with an H' value of 2.15. This indicated that the diversity of pollinating insects at the study site was in a stable condition because there were no pollinating insect species that were too dominant.

Health is an important thing for human life, including the health of the human movement system. Some people think that disorders or diseases of the locomotor can occur in people who are elderly or elderly. However, nowadays many people their productive age and even teenagers experience disorders or diseases of their moving organs. The problem that often occurs in the movement system is tremors in the hands which can occur at both old and young ages. This study aims to examine the relationship between lifestyle and movement system disorders (tremors) using qualitative methods through interviews, observation, and documentation in data collection. Based on the results obtained, 16.7% of respondents had experienced tremors. And then 83.3% of respondents stated that they experienced muscle pain. This is in line with the response of more than 80% stating that they often do heavy work and consume caffeine.

Studies on the diversity of nocturnal insects in the city of Palembang, especially in the Pertamina Bagus Kuning Complex, Palembang, are still limited, so it is necessary to carry out research on the diversity of nocturnal insects in the area. This study aims to determine the level of diversity of nocturnal insects active in the Pertamina Bagus Kuning Complex. This research was conducted in December 2022. This research was conducted using light traps as a place to catch nocturnal insects. The method used is a descriptive survey by direct observation of insects in the Pertamina Bagus Kuning Complex. The number of light traps used was 2 traps placed at 2 different stations, the light traps were placed at 18.00 WIB and collected the next day at 05.30 WIB. The results showed that nocturnal insects caught by light traps were 35 individuals from 8 species and 5 orders. The diversity of nocturnal insect species in the Pertamina Bagus Kuning Complex area based on Shannon-Weiner (H') of 1.74753679 is classified as moderate.

Interest in learning is important in supporting student academic achievement. This often happens in biology subjects in the classroom. Many students expressed boredom in the lesson. Therefore, researchers will dig deeper related to aspects of student's interest in biology learning. The method used is literature study, which analyzes previous research. The results obtained are factors that influence student learning interest in biology subjects depends on student interest in teachers when teaching, interest in biology subjects, feeling happy with the way teachers teach and delivering material, attention to biology subjects, and being involved in the learning process and student tenacity when learning. In addition, internal factors (physical health, drive, arousal, and grasping ability) and external influences (environment, parents, teachers, learning styles, etc.) can affect students' interest in learning, the most important in interest in learning biology in the classroom is the initial and strong intention that students have when learning biology begins in class

Syzygium is one of the flora from the Myrtaceae family which is used by Indonesian people in various ways. This article is structured to analyze the various roles of the Syzygium species. The method used in preparing this article is a study of literature from various reputable international journals. Several types of Syzygium discussed in this article are S. jambos, S. fibrosum, S. cumini, S. malaccense, S. samarangense, S. densiflorum, S. grande, S. aromaticum and others. Plants belonging to the Syzygium have various roles including as a food ingredient, a role in agriculture, as a bioremediation agent for polluted environments and as a medicinal ingredient. The role of Syzygium in agriculture includes as a natural pesticide and as a weed control agent. The role of Syzygium in the environmental field is as a bioremediation agent for environments polluted by heavy metals, soil polluted by industrial waste and waterlogged soil with high salinity. Phytochemical compounds found in Syzygium cumini have the potential to be used as medicinal ingredients because they have therapeutic effects because they contain anthocyanins, phenols and polyphenols, compounds that function as antioxidants and anti-inflammatories that function to control oxidative stress in preeclampsia. With this article, it is hoped that the public will be able to find out the various roles of plants from members of the Syzygium so that they can make maximum use of them.

21st Century Learning requires educators to be able to develop teaching materials in accordance with ICT developments and the needs of students. Electronic LKPD based on a constructivism approach to circulation system material for high school students was developed to help students become more interested and active in learning, understand material easily, and show the process of absorbing information so as to create meaningful learning. The type of research used is development research using the Intructional Development Institute (IDI) model which has 3 stages, namely define, develop, and evaluate. The subjects in this study were two lecturers of biologists at Padang State University, one biology educator and 30 students of class XI IPA at SMA Negeri 1 IV Koto. The object of this research is electronic LKPD based on constructivism approach on circulation system material for high school students. The research instruments used were educator interview questionnaires, student questionnaires, validity test sheets, and practicality test sheets. The results of the validity test of this electronic LKPD were 90.10% in the very valid category and the results of the practicality test of this electronic LKPD were 89.66% in the very practical category. It can be concluded that the electronic LKPD based on the constructivism approach on circulation system material for high school students gets very valid and very practical values.
