Abstract

Antibiotics are chemical compounds that can be produced by certain microorganisms and can inhibit growth or kill microorganisms. Antibiotics can also be produced by plant cells which are produced from secondary metabolites of the plant itself. To determine the potential or inhibitory activity of an antibiotic against the growth and development of bacteria, a microbiological assessment can be carried out using the diffusion disk method (filter paper (Kirby and Bauer)). As many as seven disk were made of NA (Nutrient Agar) media in a Petri dish. Each sample was sorted to obtain sufficient liquid extract. The extract pipette of each sample with the micropipette in the diffusion disk provided is labeled. The diffusion disk was then inoculated in an incubator using a temperature of 37oC for 48 hours. Negative control (sterile water), positive control (antibiotic Amoxicillin). Inhibition activity of ginger rhizome extract on Gram-positive bacteria was 36.75%, and Gram-negative bacteria was 42.29%. The inhibitory activity of betel leaf extract on Gram positive bacteria was 18.97%, and Gram negative bacteria was 16.6%. Inhibition activity of turmeric rhizome extract on Gram positive bacteria was 17.39%, Gram negative bacteria was 20.94%. The inhibitory activity of juwet leaf extract had the largest percentage of Gram-positive and Gram-negative as much as 73.12%. Meanwhile, the inhibitory activity of mint leaf extract with the smallest inhibition percentage was Gram positive and Gram negative was 0%.

Abstract

Learning model is a whole series of teaching material presentation which includes all aspects before and after learning. The problem in this study is that student learning outcomes are still lo and lacking enthusiasm in the learning process, where the value of student learning outcomes is still much below the KKM. This type of research uses PTK, with a quantitative data collection in the from of student learning outcomes tests and qualitative data obtained from intervies and studend documentation data. With 23 students as research subjects. Based on the results of this study, the average cognitive score of srtudentd in cycle I was 73. In the first cycle the average cognitive score of students II was 82, so there was an increase of 9%. So the application of the RCCDE learning model can improve students learning outcomes in the material of interaction of living things with the environment so that it can help in the student learning proses.Keywords: RCCDE model, learning outcomes, the interaction of living things with the environment

Abstract

Media dalam dunia pendidikan digunakan sebagai alat dan bahan dalam kegiatan pembelajaran untuk memberikan informasi dari guru  ke siswa. Berdasarkan hasil wawancara, diperoleh data hasil belajar siswa masih rendah yaitu sekitar 40 % masih di bawah KKM. Jenis penelitian ini adalah PTK. Analisis data menggunakan pendekatan kuatitatif, sedangkan metode pengumpulan data diperoleh dari tes objektif dan dokumentasi. Tujuan dari penelitian ini adalah untuk meningkatkan hasil belajar siswa menggunakan Media Peta Jelajah Taman Botani. Dengan subjek penelitian berjumlah 29 orang. Berdasarkan hasil belajar siswa pada siklus I diperoleh hasil rata-rata nilai kognitif siswa 87,6 meningkat menjadi 95,9 pada siklus II. Sedangkan hasil nilai ketuntasan klasikal pada siklus I sebesar 96,5% meningkat menjadi 100%  pada siklus II. Hal tersebut membuktikan bahwa pembelajaran melalui penerapan media Peta Jelajah Taman Botani sangat efektif untuk meningkatkan hasil belajar siswa.

Abstract

ABSTRACT Biopesticides are natural pesticides that come from nature such as leaves, roots, stems, and fruit. This research is about the efectiviness of papaya (Carica papaya) biopesticide with cow urine fermentation in sweet corn (Zea mays L. saccharata), which was conducted in Glagahwero Kalisat, Jl. Mayangan, Desa Glagahwero, Kec. Kalisat, Kab. Jember this study aims to determine the effectiviness of biopesticides on sweet corn (Zea mays L.saccharata). This type of research is experimental. The procedure used was a Completely Randomized Design (CRD). Based on the results of research, the effectiviness of biopesticides using papaya leaf fermentation is not effective due to several factors, namely the season is not right, the planting area is not right, the plant layout is not good, grasshopper pests are difficult to control. Keywords : Plant Papaya (Carica papaya), Plant Sweet Corn (Zea mays L. saccharta)

Abstract

One of the bacteria growing media that is often used in laboratories is Nutrient Agar (NA). However, the price of this bacterial growth medium is relatively expensive. The high price of media and the abundance of untapped natural resources have encouraged researchers to find new alternative media from simple ingredients. Tubers contain high carbohydrate content so they have the potential to be used as the medium. This study used Nutrient Agar as a control as well as two varieties of canna tubers (Umbi Ganyong), namely white canna and red canna. This research is an experimental study to determine the effectiveness and characteristics of canna tubers as a medium for bacterial growth, which in this study used three variations of the concentration of canna tuber powder (10, 20, 30) grams per 600 ml aquadest. The results showed that bacteria can grow on media made of 20 gr/600 ml white canna tubers with the highest number of bacterial colonies of 9,5. 103 CFU/ml. This proves that white canna tubers are much more effective as a medium for growing bacteria compared to red canna tubers.

Abstract

Fungi are eukaryotic organisms that have spores, are nucleated, do not have chlorophyll, and are threadlike with cell walls composed of cellulose and chitin. Fungi are heterotrophic microorganisms that are saprophytic or parasitic. Fungi have spherical or filamentous cell structures called hyphae. Hyphae are divided into two, namely fertile hyphae which form reproductive cells and upward growth as air hyphae and vegetative hyphae, namely hyphae that seek food into the substrate. Certain conditions, the nature of fungi can turn into pathogens and cause various diseases. Some fungi that contaminate food have the ability to produce toxins or poisons that can cause disease. This research was conducted on samples of garlic, turmeric, chilies, and candlenut which were planted on medium (potato dextrose agar) and incubated for seven days. Observation of fungi growing in each sample was carried out macroscopically and microscopically. Macroscopic observations by observing colony color and colony reverse color, while microscopically observed fungi morphology and hyphae type using a microscope with a magnification of 10 x 40. The identification of funguswas obtained by observing the samples of garlic, turmeric, and candlenut were overgrown with Aspergillus niger. The fungus in the chili sample was Rhizopus stolonifera. Based on these results, it can be conclude that two types of fungi that were found, have different characteristic both macroscopic and microscopic. Keywords: Fungi, macroscopic and microscopic observations, Aspergillus niger, Rhizopus stolonifer.

Abstract

Water has a very big role, one of which is for biological needs, namely survival. The main problem faced with regard to water resources is water quality. Determination of water quality by microbiology is done by using the Most Probable Number (MPN) Test. This study used 3 samples, namely well water, bottled water, and river water. Well water contains the same amount of Coliform and Escherichia coli, namely 14 MPN / 100 mL. In the presumptive test, bottled water showed positive results, but when tested for the determination it was obtained negative results. Meanwhile, river water contains more than 1100 MPN / 100 mL of coliform bacteria and 11 MPN / 100 mL of Escherichia coli. Bottled drinking water samples are suitable for consumption, while well and river water samples are not suitable for consumption because they contain Coliform and Escherichia coli.
