Abstract

A Needs assessment is the first step that must be done in learning design activities. Needs assessment Analysis is done when facing problems in a lesson. The problems that are commonly encountered in learning Genetics courses are several scientific terms that are similar to one another and are considered difficult by most students. This has an impact on students' conceptual and factual understanding is low. Through the Needs Assessment instrument in the form of a questionnaire survey for lecturers and students, as well as observations identified problems in order to determine the right action, so that the learning design that will be carried out is the best solution. The survey results obtained are summarized and concluded as problem identification and then analyzed to find the right solution. The solution to the identification results obtained is learning the Karyotype Group Strategy, namely the first; class organization based on the shape of the grouping of chromosomes. Second; learning begins with forming groups or organizing classes, because at the same time it is a form of simulation of the core material of learning Genetics.

Abstract

Adding the nutritional content of broth powder without destroying the distinctive taste of the broth can be doneusing pure mushroom extract and additional vegetables and spices. This study aims to determine the organolepticcharacteristics and identify the chemical functional groups of glutamic acid in the best samples of oyster mushroombroth powder added with vegetables and spices. The results of the organoleptic test were tabulated in a table andthen analyzed using a descriptive test. The organoleptic characteristics of the best color parameters were intreatment B1 which had a pale white color. The best treatment of aroma, texture, and taste parameters were foundin the B2 treatment with a characteristic aroma of typical broth, fine powder texture, and has a distinctive taste ofbroth. The identification of the functional groups of secondary metabolites using the Fourier Transform Infrared(FTIR) instrumentation. Identification results with FTIR showed absorption at wave number (cm-1): 3419.74,2934.62, 1639.56, 1409.70, 1055.55. There is N-H, O-H, C-H, C=O carbonyl group and carboxylic C-O, whichidentify the presence of amide compound, phenol acid, alkane, aldehydes, amid I and carboxylic acid, which areknown as glutamic acid in this sample.

Abstract

Biodiversity learning in senior high schools is often abstract and weakly connected to students local socio-ecological realities. Local ethnobotanical knowledge can provide a contextual basis for more meaningful biodiversity learning. This study aimed to develop and evaluate Dayak ethnobotany-based biodiversity teaching materials for Grade X students. The study used a Research and Development design with the ADDIE model. The participants were 23 tenth-grade students from one intact class and two biology teachers at SMA Negeri 1 Uut Murung, Central Kalimantan, Indonesia. The student sample represented a limited field trial to examine the feasibility and initial effectiveness of the product in a real classroom context. Data were collected using expert validation sheets, teacher and student response questionnaires, and learning outcome tests with a one-group pretest-posttest design. Product validity using Gregory’s formula obtained a score of 1.00, indicating very high validity. Practicality scores reached 95,5% from teachers and 91,5% from students. Learning outcomes increased from 47.25 to 89.86, with an N-Gain score of 0.83, categorized as high. The greatest improvement occurred in students cognitive understanding of biodiversity, especially its relationship with the local environment and local wisdom-based in conservation. Thus, the teaching materials are valid, practical, and effective for contextual biodiversity learning.

Abstract

The aim of this research was to know the difference of ethanol extract and extract of ethyl acetate of pepper leaf (Piper nigrum L) to antimicrobial activity of Staphylococcua aureus, Escherichia coli and Candida albicans. The maceration method has been used to extract the pepper leaf by using two solvents ie 70% ethanol and ethyl acetate. The extract results were then tested for antimicrobial activity. The result of pepper ethanol extract obtainedby the higher yield was 24,64% compared with ethyl acetate extract 9,18%. Leaf pepper ethanol extract had higher antimicrobial activity than pepper acetate leaves extract against Staphylococcua aureus, and Escherichia coli but did not inhibit Candida albicans fungi at concentration of 10%

Abstract

Pegagan atau yang dikenal dengan nama Pegagan merupakan tanaman perdu yang mengandung zat gizi dan senyawa aktif yang baik bagi tubuh, karena memiliki khasiat sebagai antibakteri, antivirus, antihipertensi, diuretik dan antiinflamasi. Tanaman ini merupakan sumber senyawa fenolik, flavonoid, triterpenoid, alkaloid dan tanin. Penelitian ini bertujuan untuk mengevaluasi aktivitas antibakteri daun pegagan. Daun pegagan diekstraksi dengan pelarut etanol 70%, kemudian difraksinasi dengan pelarut n-heksana, etil asetat dan metanol. Evaluasi aktivitas antibakteri menggunakan metode difusi cakram pada konsentrasi 5%, 10% dan 15% terhadap Escherichia coli dan Staphylococcus aureus dengan mengukur zona bening yang terbentuk di sekitar kertas cakram. Hasil penelitian menunjukkan bahwa ekstrak etanol 70%, fraksi etil asetat dan fraksi metanol:air memiliki aktivitas antibakteri terhadap kedua bakteri tersebut, sedangkan fraksi n-heksana tidak memiliki aktivitas antibakteri terhadap kedua bakteri tersebut. Ekstrak etanol dengan konsentrasi 5% menunjukkan aktivitas paling efektif dalam menghambat Escherichia coli dengan zona hambat 13,67 ± 0,428 mm dan fraksi metanol:air dengan konsentrasi 5% terhadap Staphylococcus aureus dengan zona hambat 9,35 ± 0,17 mm.
