Abstract

This research aims to examine the forest types, inventory of tree species, and chlorophyll content of plant leaves in the Malabar forest, Malang City. This type of research is descriptive quantitative. This research was done from the month of August to December 2020 and took place in Malabar Forest and Biology Laboratory of University of Muhammadiyah Malang. Data collection methods using exploratory techniques and laboratory observations. Data analysis is done by descriptive quantitative. The results showed that 101 tree species inhabit Malabar forest with the most Tanjung trees with 175, and the least number is Srikaya with only one tree. Malabar forest is classified as a forest with a spreading form. In the dry season, the average chlorophyll ‘a’ content of leaves was highest in starfruit leaves (35.848 µg/ml), the lowest average of starfruit leaves (17.857µg/ml), the average chlorophyll ‘b’ content of leaves was highest in Tabebuya leaves (58.862µg/ml). The lowest was Norfolk Pine leaf (9,124 µg/ml), the highest total leaf chlorophyll was Tabebuya leaf (91,737µg/ml), and the lowest was the Norfolk Pine leaf (28,517µg/ml). In the rainy season, the highest chlorophyll ‘a’ content was Sengon tree (34.3µg/ml) and the lowest was Chocolate (0.3µg/ml), the highest chlorophyll ‘b’ was Genitu (131.6µg/ml) the lowest was Lamtoro (6.5µg/ml), the highest total chlorophyll was Melinjo (90.7µg/ml) and the lowest was Kol Banda (3.3µg/ml). Keywords: Malabar Forest, Inventory, Leaf Chlorophyll.

PEMBELAJARAN INTERAKTIF BERBASIS ICT (INFORMATION AND COMMUNICATION TECHNOLOGY) DALAM MATERI VERTEBRATA PADA SISWA MA MUHAMMADIYAH 1 MALANG Nurisma Afifatun Nisa1, Roimil Latifa1, Moch. Agus Krisno Budiyanto1 1Pendidikan Biologi FKIP Universtias Muhammadiyah Malang, e-mail: biologi.umm@gmail.com ABSTRAK The development of ICT in Indonesia increasing along with the time passed by. Hopefully little by little the teacher start to accustomed to used ICT based learning to adapt with the mushroom growth of time mowdays. Interactive learning media based on ICT hopefully be able to help students in comprehend the difficult materials which complicates to be mastered by the students especially in vertebrate material. In this interactive learing media development research at vertebrate material serve the purpose of learning media for student and teacher to facilitate teacher in deliver the material, also the researcher be able to know the usage of interactive learning media based on ICT in the effectiveness of student learning. This research codunsted at 10 March 2013 until 19 Octobeer 2013 in MA Muhammadiyah 1 Malang. The result of this development is produce interactive learning media product based on ICT (Information and Communication Technology) that have been made.which is had pass through testing process and revised based on suggestion and input from material expert and media expert also comment from the trial run student. Student learning activity getting off the ground from dependent class to independent class. The effectiveness of learning result and process in interactive learning media development based on ICT to increasing student achievement grade X student of MA Muhammadiyah 1 Malang getting off the ground based the data that have been obtained.

Abstract

Recently, the necessity of foods has been fulfilled by using various methods without considering hygiene level and sanitation during its processing. One of food processing which is assumed as unhygienic cuisine is fish-paste. Fish-paste is commonly made from side product of boiling fish or shrimp. It has a thick viscosity with salty-sweet or sweet-spicy taste and can be used as food seasoning. The study is descriptive qualitative and aimed identify the content of Salmonella sp. and Escherichia coli in fish-paste in Klampis market of Bangkalan Madura; moreover, to assess if the paste is safe to consume and fulfilling the requirement of food-safety-standard based on SNI. The results research were used to compose biology learning resource as practical guidance. This research employed spread-plate method. As many as 7 samples were assessed by three multiplications. The results were compared to Indonesia National Standard 2009 of maximum level of microbe contamination on fish and fish-product including Mollusca, Crustaceae, Echinodermata which were processed. The research results showed that there were no finding neither Salmonella sp nor Escherichia coli on the paste tested. These results were utilized as biology learning resource.

Abstract

Malabar, as an urban forest has a potential in CO2 sequestration which was not documented yet. This quantitative descriptive research aimed to describe the contribution of Malabar urban forest in CO2 emission mitigation through calculating the amount of CO2 absorbed by the forest. The data collection used was non-destructive in which the indicators measured were DBH and the height of the trees with DBH more than 20 cm. The data gained then was analyzed using Alometric Chave formula to obtain the amount of plant biomass, carbon values, and CO2 values. The results showed that the potential of Malabar rban forest is not optimized yet as the low amount of carbon stored in this forest. Thus, it is suggested to enrich the trees planted with those which can sequestrate CO2 in much higher amount compare to the exist one.

Abstract

Abstract This current research aimed at investigating chlorophyll content of various plants growing in the city forest of Malabar Malang. Descriptive quantitative method was employed as the research design. This research was conducted from April to August 2019 in city forest of Malabar and Biology Laboratory University of Muhammadiyah Malang. The data were analyzed by means of Microsoft Excel. There were three steps of the research, as follows: a) surveying the research location; b) taking samples of each leaf; and c) laboratory testing. Laboratory testing comprised some stages, as below: a) weighing each leaf sample at 0.3 gram, grounded and dissolved in 80% acetone; b) filtering by utilizing filter paper, and c) testing by means of spectrophotometer with the wavelengths of 645λ and 663λ, respectively to result in absorbance value. The results of absorbance value were tabulated into a specific formula to find out the content of chlorophyll a, chlorophyll b, and the total chlorophyll of each leaf sample. This current research has revealed that regarding the average scores, chlorophyll a has been found the highest in Averrhoa bilimbi leaf (35.848 µg/ml) and the lowest is in Averrhoa carambola leaf (17.857 µg/ml). The average score of chlorophyll b has been found the highest in Tabebuya leaf (58.862 µg/ml) and the lowest is in nortflok pine leaf (9.124 µg/ml). As for the total average of chlorophyll content, the highest content was extracted from Tabebuya leaf (91.737 µg/ml), and the lowest is found in nortflok pine leaf (28.517 µg/ml).
