The results of the pre-survey at MA Ma'arif 03 Seputih Banyak shows that there was a problem found, which was the lack of use of learning media when teaching biology material, including biodiversity material. In the learning process, the learning resources used only focus on student worksheets and students have not directly interacted with their surroundings. This causes some students to find it difficult to understand the material presented. Therefore, it is necessary to develop biodiversity-based learning media. This study aims to develop a flashcard based on the diversity of freshwater fish in the Sakti Buana River as a learning medium for students in Senior High School/Islamic Senior High School (MA). This research is included in the type of Research and Development (R&D) research using the ADDIE development model which consists of five stages, namely Analysis, Design, Development, Implementation, and Evaluation. From the results of product validation and testing, the percentage number of each respondent includes by media experts is 91.67%, by material experts is 90%, by teacher responses is 90%, by student responses is 91.25%, and all the results belong to the category "very feasible." Based on the validation by both validators and the product test results, it is shown that the flashcard based on the freshwater fish diversity in the Sakti Buana River as a learning medium for Islamic Senior High School (MA) students is very feasible to use.
在MA MA 'arif 03 Seputih Banyak的预调查结果显示，发现了一个问题，即在教授生物材料，包括生物多样性材料时，学习媒体的使用不足。在学习过程中，使用的学习资源只集中在学生的工作表上，学生没有与周围环境直接互动。这导致一些学生发现很难理解所呈现的材料。因此，有必要开发基于生物多样性的学习媒体。本研究旨在开发一种基于Sakti Buana河淡水鱼多样性的抽认卡，作为高中/伊斯兰高中(MA)学生的学习媒介。本研究属于研发类研究，采用ADDIE开发模型，分为分析、设计、开发、实施和评估五个阶段。从产品验证和测试的结果来看，媒体专家、材料专家、教师和学生的回答比例分别为91.67%、90%、90%和91.25%，均属于“非常可行”的范畴。基于验证者和产品测试结果的验证，表明基于Sakti Buana河淡水鱼多样性的抽认卡作为伊斯兰高中学生的学习媒介是非常可行的。

This study aims to identify the forms of starch in edible plants. This research involved several edible plants such as sago, yam and taro. This type of research uses descriptive quantitative methods by conducting experiments on each sample used. The data collection technique was carried out by describing the results of the starch form from each sample that had been obtained. The results obtained from this study showed that the Sago preparations viewed under a microscope had an oval starch shape and spread throughout the preparation so that it was classified as an eccentric starch type that could be seen at 10X magnification, while Jicama starch preparations had a round starch shape and chains in some parts. The plane of the preparation and entered in the concentric type, but the shape of starch in Jicama can be seen under a microscope at 100X magnification, the Taro preparation has a round and lumpy shape but the starch accumulates in several areas of the preparation and enters the concentric type seen at 40X magnification. So it can be concluded that the forms of starch in edible plants are very diverse, both in round to oval shapes, with smooth and rough starch structures, namely in the form of lumps.

Diseases caused by mosquitoes continue to be the leading cause of illness and death worldwide. Malaria, filariasis, Japanese encephalitis and dengue fever are diseases that are clearly transmitted by mosquitoes of the genera Anopheles, Culex and Aedes. In addition, mosquitoes in the Culex genus have also been identified as the main vectors that transmit WNV (West Nile Virus) in several countries. One of the efforts to eradicate mosquitoes is to break the chain of mosquito distribution by eradicating mosquito nests and killing mosquito larvae. The use of abate insecticides as larvicides can be the most common way of controlling the growth of mosquito vectors. The use of abate for a long time will cause resistance or the larvae will be immune to abate (insecticide). Shallot skin has the potential to be developed as a biolarvicide for Culex sp mosquito larvae due to its phytochemical compounds. Onion peel waste was proven positive for containing alkaloids, saponins, flavonoids and tannins. The purpose of this study was to determine the effective concentration of onion peel waste powder (Allium ascalonicum) and the effective LC50 of onion peel waste powder (Allium ascalonicum) as larvicides against the death of Culex sp mosquito larvae at an effective powder concentration of 0.025 gr/ml, 0.05 gr. /ml, 0.075 gr/ml and 0.1 gr/ml. This type of research is an experimental laboratory, carried out from August to September 2021 at the Microbiology Laboratory of D III Study Program Medical Laboratory Technology, Health Poltekkes, Aceh Ministry of Health. The sample of this study was 325 larvae of Culex sp Instar III mosquito larvae. The treatments consisted of 4 effective concentrations of onion peel powder 0.025 g/ml, 0.05 g/ml, 0.075 g/ml and 0.1 g/ml and a negative control (Water) with 3 repetitions. Each treatment group contained 25 larvae. The data obtained were analyzed using the formula for the percentage of mortality of Culex sp larvae and the Probit analysis test to calculate the LC50. The results showed that the average larval mortality at a concentration of 0.025 gr/ml was 8 birds (32%), a concentration of 0.05 gr/ml was 9 birds (37%), a concentration of 0.075 gr/ml was 11 (44%), and the concentration of 0.1 g/ml is 16 animals (64%). While the negative control did not show death. And the LC50 value at 24 hours after treatment from the concentration of onion peel powder was 0.075%. Based on the results of the study, it can be concluded that onion peel powder (Allium ascalonicum) has the potential as a natural larvicide against the mortality of Culex sp larvae with LC50 obtained at an effective concentration of 0.075% powder.

Peanuts make a significant contribution in meeting the needs of legumes, especially in Southeast Aceh Regency. This research was conducted in Kisam Village, Bambel District, Southeast Aceh, with an altitude of ± 220 m above sea level. The aim of the study was to determine the application of liquid organic fertilizer and the dose of NPK fertilizer on the growth and development of peanut (arachis Hypogea L.) plants. The design used in this study was a Randomized Block Design (RAK) which was arranged in a factorial manner with 9 treatment combinations with 3 (three) replications. The treatment consisted of 2 (two) factors, namely the first treatment of liquid organic fertilizer (P1) 2cc/l water, (P2) 4 cc/l water and (P3) 8 cc/l water, while the second factor was the dose of NPK fertilizer (N1 ) 1.25 g/plant, (N2) 1.75gr/plant and (N3) 2.25 g/plant. The observed variables were plant height, number of branches, number of petioles and number of leaves. The results showed that the application of liquid organic fertilizer (P1) gave the best results on plant height, number of branches, number of petioles and number of leaves. Dosage of NPK (N3) fertilizer gave the best results on plant height, number of leaves. The interaction of treatment with liquid organic fertilizer (P1) and dose of NPK fertilizer (N3) gave the best effect on the growth and production of peanut plants. The results of the analysis of variance showed that there was no significant interaction between the treatment of giving liquid organic fertilizer (Pocnasa) and chemical fertilizer (NPK Biru) to all observed variables.

The data analysis includes the Important Value (NP) and Species Diversity Index (H'). The results showed that the species composition of trees growing on the campus of Syiah Kuala University were 46 species belonging to 27 families. Six tree species that had relatively high importance value compared to others, namely Pterocarpus indicus (19.61%), Swietenia mahagon i (19.56%), Polyathia longifolia (12.76%), Mimusops elengi (12.48%), Roystonia regia (12.27%), and Samanea saman (10.176%). The Diversity Index (H') of those tree species ranged from 1.549 to 2.634. The conclusion is that the tree species composition was relatively limited when compared to the Cronquist classification, and the tree species diversity index was in the medium category.

This type of research uses the Research and Development (R&D) method with reference to the Borg and Gall research model. This research was conducted at Senior High School 4 Regency Tangerang on May until June 2021. Research data obtained by way of spreading questionnaires to the 1 validator material expert, 1 validator media expert, 1 biology study teacher, and 30 students of Senior High School 4 Regency Tangerang in MIA. The results of the research in terms of media received an assessment of 95.8% and got 98,1% in terms of material with both getting a very good category. Tests on the limited-The scale on students to the development of contextual-based Biology Digital Book learning media obtained a score of 91.4% with a very good category. The results of the student response test showed that the contextual-based Biology Digital Book learning media product on plant material (plantae) of the moss sub-concept was very good to be tested on a large scale (main field test). This deficiency in learning media can be corrected in the relevant further development research.
