Creating students who are superior in spiritual and scientific terms can be done through learning activities that integrate Islamic science. The integration of Islamic science in science-biology learning can be done using the Al-Qur'an integration model as a source of inspiration and confirmation. The aim of this research is to describe the planning, implementation and evaluation of the implementation of the integration of science and the Koran in science-biology learning on respiratory system material for class VIII students at MTs Negeri 3 Blitar. The type of research used is descriptive qualitative research with data collection techniques using interview, observation and documentation methods. The results of the research show that of the two class VIII teachers, namely SA1 and SA2, one of them (SA2) implemented the integration of Al-Qur'an science into the respiratory system material which can be seen from the planning, implementation and evaluation stages of the learning carried out. SA1 has not implemented the integration of Al-Qur'an science at the planning and evaluation stages. SA1 has implemented Al-Qur'an science at the implementation stage, but not in the respiratory system material. Therefore, this integration is a form of development carried out by teachers personally so that not all teachers have the ability to implement it.

The use of plastic is still favored by most people today, which has increased the amount of plastic waste. One of the bacteria that can carry out plastic bioremediation is found in mangrove ecosystems. The existence of the mangrove ecosystem is found on Sine Tulungagung Beach, but there has never been further exploration regarding the presence of plastic-degrading bacteria. This research was conducted to explore the presence of potential plastic-degrading bacteria in the mangrove area of the Sine Tulungagung coast. This study used a descriptive-qualitative method that began with planting plastic samples in mangrove deposits, followed by taking bacterial samples from the mangrove area of Sine Beach, Tulungagung. 21 bacteria were isolated from the exploration and tested for their ability to reduce the weight of the plastic. Bacteria with the ability to decompose plastic were then identified using morphological (color, shape, edges, elevation, and size) and biochemical (gram staining and catalase enzyme) tests. It was found that the highest plastic weight reduction was 6.97%, with the most characteristics in the form of coccus and gram-negative bacteria.

Dragonflies also play a role in ecosystems as predators and bioindicators of water quality. The study aims to determine the community structure and diversity of dragonflies in Lake Aqua. The study was conducted in April 2021. Type of qualitative descriptive research, with visual day flying method with 3 observation locations based on vegetation composition and ease of access. Sampling using insect nets, documentation and identification. Based on the results of the study, 10 species of odonata were obtained, including 5 species of dragonflies (Anisoptera) and 5 species of needle dragonflies (Zygoptera). The total number of dragonflies found in 3 locations was 337 individuals from 6 families, including Euphaea variegata, Heliocypha fenestrata, Rhinocypha heterostigma, Vestalis luctuosa, Coeliccia membranipes, Onychogomphus fruhstorferi, Orthetrum glaucum, Orthetrum pruinosum, Orthetrum sabina, and Pantala flavescens. The results of the diversity index (H') showed 2.04 medium categories, the highest abundance was found in the species Euphaea variegata which was valued at 24.9% and the lowest abundance was found in Coeliccia membranipes worth 1.2%. The evenness index of 0.9 is high, the dominance index of 0.2 is low, which means dragonflies have the same opportunity to utilize resources. The calculation of the Family Biotic Index (FBI) to 3 locations of 0.02 is included in the category of very good water quality. The higher the number of dragonflies in the ecosystem, indicating that the ecosystem is still natural and environmental sustainability is maintained. When pollution occurs in the waters, it causes the life cycle of dragonflies to be disrupted and their population to decline.

This study aimed to evaluate the antibacterial activity of clove leaf essential oil (Syzygium aromaticum) against heterotrophic bacteria isolated from food products. Clove leaves were collected from Malang Regency, Indonesia, and the essential oil was extracted via steam-water distillation. Bacterial isolates were obtained from food samples using serial dilution and pour plate techniques. Antibacterial activity was assessed using the agar diffusion method at three oil concentrations (50%, 75%, and 100%), with Amoxicillin trihydrate as the positive control and sterile distilled water as the negative control. The morphological characteristics of the isolates were documented, and inhibition zones were measured. Results indicated that inhibition strength increased with oil concentration up to 75%, with the largest numerical inhibition observed against isolate K2 at 100% concentration (31.3 mm), approaching the positive control’s efficacy. Statistical analyses confirmed that differences among treatments were significant (p < 0.001), except between 75% and 100% concentrations, suggesting a plateau in activity beyond the minimum inhibitory concentration. The findings highlight clove leaf essential oil’s potential as a natural antibacterial agent for food preservation, offering an environmentally sustainable alternative to synthetic antimicrobials. However, in vitro conditions may not fully represent performance in real food matrices, warranting further research on its application, stability, sensory effects, and synergistic combinations with other natural antimicrobials.
