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.

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.

Sun, 29 Oct 2023 15:29:31 +0700

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.

Analisis Aspek yang Mempengaruhi Ketertarikan Siswa SMA dalam Pembelajaran Biologi

Sun, 29 Oct 2023 15:55:33 +0700

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
