The use of teaching media in the 4th Grade of SDN Sukorejo IV, Sukerejo District, Pasuruan Regency has not been maximal, thus resulting the decreasing level of students’ motivation during the learning session. Then, it is needed an effort to escalate the students’ motivation in learning through the development and utilization of learning media. This research is conducted to produce The development of Touch and Play 3D Images Learning Media Based on Adobe Flash in the Five Senses Subject at 4th Grade of Elementary School, and to describes The students’ responses in the implementation of touch and play 3D images learning media based on Adobe Flash in the Five Senses Subject at 4th Grade of Elementary School. The research show that: The development of Touch and Play 3D Images learning media based on Adobe Flash in the Five Senses Subject at 4th Grade of Elementary School using the design of research and development stated by Borg and Gall. This design has 10 phases, but the researcher only applied 7 phases due to the phases which already modified, which are the potential and problems, data collection, design product, design validation, design revision, product testing, product revision. The Touch and Play 3D Images media in the Science Subject, The five senses Subject of 4th Grade students is part of the worthy to be used. Validity test held by the expert of the subject obtained the 87.5 % percentage within the Valid Category. The test of validity by the learning expert gets the percentage value of 97.2% included in the valid category. The average result of the student's response shows the percentage of 97.61% is included in either category. In conclusion, the Touch and Play 3D Images based on Adobe Flash in the five senses subject of 4th Grade Elementary Students can be considered as Valid as the learning media.

The aim of the research were to evaluate the efficacy of botanical insecticide of S. mahagoni leaves extracts against larvae of Ae. aegypti, based on concentration of the leaves S. mahagoni extract, and in additional to determine secondary metabolites compounds of S. mahagoni leaves extract. The extraction of S. mahagoni leaves was done by using ethanol solvents and than was analyzed by using Thin Layer Chromatography. The result indicated that ethanolic extract of S. mahagoni leaf contained alkaloid, tannin, saponin, terpenoid, and flavonoid compounds. The value of LC50 and LC90 calculation showed that LC50 of ethanolic extract over second and third instar larvae respectively were 488 ppm and 644 ppm. However the value of LC90 of both instar larvae were 732 ppm and 797 ppm. Based on the above result, it can be concluded that ethanolic extract of S. mahagoni leaf was effective against larvae of Ae .aegypti.Key words: Ae. aegypti, S. mahagoni, botanical insecticide

Publisher : UNIVERSITAS PGRI MADIUN

MOL contains superior microorganisms as decomposers activators of organic materials that can be used as plants fertilizer. The microorganisms that was contained in MOL was commercial biological agents. One way to get commercial biological agents was to look for potential bacteria that have a function as biofertilizer. The objective of this study was to screen for indigenous bacteria from MOL Bintaro fruit (Cerbera manghas L) that plays a role in the manufacture of biological fertilizers. The stages of this study were MOL making and sampling, sampling and bacterial screening by doing isolation and purification, continued by phosphate solvent bacteria test and IAA screening producing bacteria, then bacteria identification morphologically. The result of isolation and purification found that there were 35 kinds of bacteria from two samples of MOL Sample 1 was treated as 3 kg of Bintaro fruit and it was found that there were 18 bacteria. Furthermore, sample 2 was treated as 1.5 kg of Bintaro fruit and got 17 kinds of bacteria. The result of bacteria solvent screening found 7 isolates. The isolated bacteria that had the greatest solubility of phosphate were MBSD 6 with P isolated solvent index was 0.7 cm. The screening results of IAA-producing bacteria showed that MBSD 7 produced the highest IAA was 37.36 ppm and MBSP18 produced the lowest isolates was 6.27 ppm.

Publisher : UNIVERSITAS PGRI MADIUN

Agung Semeru banana and Mas Kirana, is one of the typical banana varieties found in Lumajang Regency. Where on the banana peel extraction contain various antifungi compounds. The purpose of this research is to know the difference of banana extract of Agung Semeru and banana Mas Kirana varieties of lumajang, in inhibiting the growth of pathogenic fungi Candida albicans, and to know the optimal concentration which can inhibit the growth of Candida albicans. The method used was Completely Random Design (RAL) with four of factors, that is: 0, 25, 50, 75 and 100 %. The results were analyzed with Anova test and Duncan test multiple ranger test at the level of 5%. Each treatment was repeated three times. The results show that there is an effect of giving extract of Semeru banana peel (sig = 0,00) and banana Mas Kirana (sig = 0,00) to Candida albicans growth at various concentration (0%, 25%, 50%, 75% and 100%). For extract of Semeru banana peel at concentration 75% (3,19 ± 0,84 mm) showed better result from other concentration, while for banana Mas Kirana Lumajang peel extract, at concentration 50% (2,44 ± 0,0 mm) showed better result than treatment other. Ability of antifungal activity of Agung Semeru banana peel extract better than banana Mas Kirana.

KEMAMPUAN PEMBENTUKAN SLIME PADA Staphylococcus epidermidis, Staphylococcus aureus, MRSA DAN Escherichia coli Rini Purbowati
Florea : Jurnal Biologi dan Pembelajarannya Vol 4, No 2 (2017)
Publisher : UNIVERSITAS PGRI MADIUN

Biofilm merupakan komunitas bakteri yang terorganisasi, terakumulasi dalam metriks polimer (EPS) atau disebut juga slime yang diproduksi oleh bakteri itu sendiri dan mampu melekat pada permukaan hidup maupun tak hidup. Infeksi yang disertai dengan pembentukan biofilm sulit ditangani secara efektif oleh sistem kekebalan tubuh inang dan tahan terhadap pengobatan dengan antimikroba. S. aureus bersama dengan S. epidermidis merupakan agen penyebab infeksi antara lain infeksi implan medis dan infeksi nosokomial di seluruh dunia. Patogenesis infeksi S. epidermidis terkait dengan pembentukan biofilm. Patogenesis S. aureus disebabkan oleh efek gabungan dari faktor ekstraselular dan toksin, bersama dengan sifat invasif strain seperti perlekatan, pembentukan biofilm, dan ketahanan terhadap fagositosis. Metode Congo Red Agar (CRA) sebagai metode fenotipik yang cukup murah dan mudah dengan kriteria evaluasi didasarkan pada analisis visual warna koloni yang tumbuh pada media agar. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisa kemampuan pembentukan slime pada isolat Staphylococcus epidermidis, Staphylococcus aureus, MRSA dan E. coli. Uji pembentukan slime bakteri dengan Metode CRA dilakukan dengan menanam isolat bakteri S. epidermidis, S. aureus (MSSA 1 dan MSSA 2), MRSA 1 dan E. coli (S4 dan S55) yang telah diremajakan ke media CRA dalam cawan petri dengan metode streak 4 area. Menginkubasi selama 24 jam pada suhu 37° C pada kondisi aerobik. Interpretasi hasil menurut ketentuan sebagai berikut: strain menghasilkan koloni warna hitam pekat, hitam, dan hitam kemerahan dianggap memproduksi slime, sedangkan koloni merah dan kemerahan diklasifikasikan sebagai tidak memproduksi slime. Kesimpulan penelitian ini adalah isolat bakteri S. epidermidis, S. aureus dan MRSA dengan metode CRA (Congo Red Agar) diketahui mampu membentuk slime sedangkan isolat bakteri E. coli menunjukkan hasil yang bervariasi.

The research aimed to find the distribution of fingerprint pattern and the total ridge of students from various ethnis in Madiun. The research was conducted in five Universities in Madiun using Proportional Stratified Random Sampling method. The taking of the fingerprint was conducted by pressing the fingers of each student on the ink pad and the press them on the while paper. The fingerprint patterns were counted by percentage of each pattern and the total ridges of each ethnic were counted by average. The result of the research showed that 10 ethnic had a higher percentage of loop pattern out of 11, they are Javanese (60,4%), Dayak (69%), Flores (50,59%), Batakese (56%), Lampung (90%), Balinese (70%), Mentawai (50%), Banjar (60%), Madurese (100%), and Betawi (70%). Minang ethnic had a higher whorl pattern than other patterns, that is 70%. The highest average of the total ridge could be found in Batakese 196,33 while the lowest average of the total ridge could be found in Madurese 70. It can be concluded that there was different percentage of each pattern and each total ridge in 11 ethnic.
