BIOLOGI BUNGA TUMBUHAN NEPENTHES (N. ampullaria, N. Gracilis, dan N. Reinwardtiana.)
Jurnal Pelangi : Research of Education and Development Vol 4, No 2 (2012)
Publisher : Universitas PGRI Sumatera Barat

ABSTRACTNepenthes is a dioecious plant, that are male flowers and female flowersare separated on different individuals. Consider the threat of extinction of plantspecies of high economic value, conservation it is necessary with cultivation.Nepenthes cultivation mostly through seeds because growth through stem cuttingsis still very low. Then has done research on the biology of Nepenthes ampullaria,N. gracilis, and N. reinwardtiana. Research has been carried out from Juni 2009to Juni 2010. Androecium collected from Taratak Pesisir Selatan, Palupuh, andHPPB Andalas University Padang. Research method is a method of observationthat includes aspects of the pattern of blooming flowers. Samples taken from theoriginal habitat of flowers that bloom from the male flowers. From the resultshowed that the pattern of male flowers blooming N. ampullaria, N. garcilis andN. reinwardtiana acropetal generally the same, namely, the process of bloomingflowers in a stalk during the week and time anthesis from dawn to dusk, exceptanther dehiscens on N. ampullaria occurred several hours after the floweranthesis, whereas in N. gracilis and N. reinwardtiana immediately after theflowers anthesis. Male flowers N. ampullaria evenly bloom each flower on agroup of flower, sequentially from base to tip. After one stage of bloom, followedby a second bloom in the flower. So on until all the flowers bloom. Male flowersN. gracilis blossom one by one while at N. reinwardtiana flowers bloom ingroups, one group completed a new, gradual upward. On N. gracilis and N.reinwardtiana anthesis interest rates start to bloom at the time, whereas in N.ampullaria anthesis interest after the color changes from red to yellow.

This research has background of problem is low of students learningoutcome in Biologi Learning at MTSN Padang Sibusuk Kabupaten Sijunjung. It iscaused by some factors, such as passive students in learning, they didn’t havecooperation, and they often saw the book or asked to their friend when the testdone. Based on those problems, so the research would apply a strategy that calledverbal football. This research has purpose to know whether using verbal footballstrategy can improve students learning outcome in learning Biologi. Kinds of thisresearch is experimental research with research design is random control grouponly desigh. Population of this research are all of students at eight grade MTSNPadang Sibusuk Sijunjung. Technich of gathering sampling is purposivesampling, as experimental class is VIII2 and VIII1 as control class. Theinstrumentasi is final test of learning outcome and the data analysis is done byusing T-test. Base on analysis, taken means score of experimental class is 70,90,even though, control class is 60,18. From T-test analysis is taken tmt (2,88) > ttable(1,68). So it can be concluded that verbal football strategy by using students worksheet can improve learning outcome of Biology subject students of at eight gradeof MTSN Padang Sibusuk Kabupaten Sijunjung.

Publisher : Universitas PGRI Sumatera Barat

ABSTRAKSalah satu instrumen untuk mengukur kompetensi siswa adalah tes.Karena itu perlu bagi guru/pembuat tes untuk mengetahui validitas tesyang diberikan kepada siswa. Namun hal ini sering terabaiakan, buktinyajarang sekali guru mengevaluasi apakah tes yang diberikan kepada siswavalid atau tidak. Akhirnya tes yang diharapkan untuk mengukurkemampuan siswa kurang bisa dijadikan acuan untuk menentukan hasilbelajar. Oleh karena itu, peneliti melakukan penelitian yang berkenaandengan menentukan validitas tes agar bisa dijadikan acuan bagi gurudalam menjalankan prinsip-prinsip yang standar dalam menilai kompetensisiswa. Jenis penelitian ini adalah penelitian deskriptif dengan melakukanproses validasi terhadap tes yang akan diberikan kepada siswa. Analisisdata yaitu dengan menggunakan tabulasi data menurut Riduwan (2005:89). Dalam menentukan validasi, peneliti menggunakan tes readingcomprehension untuk semester satu kelas VIII SMP yang dikembangkanoleh peneliti sendiri. Dari analisis data diperoleh hasil validitas isi 87,5,validitas kostruk 77,3 dan validitas muka 87.5 dengan rata-rata 84.1. Halini berarti tes dapat diimplementasikan dengan sedikit revisi. Hasilpenelitian ini dapat direkomendasikan kepada para pembuat tes/guru agarbisa dijadikan sebagai acuan untuk mengetahui validitas tes yangdibuat/dikembangkan.

The purpose of this research is to disclose the influence of reward andwork motivation toward the lecturers’ performance in STKIP PGRI of WestSumatera. There were three hypotheses tested. Firstly, reward influenced thelecturers’ performance. Secondly, work motivation influenced the lecturers’performance. Thirdly, reward and work motivation collectively influenced thelecturers’ performance. The population of this research is 171 lecturers in STKIPPGRI of West Sumatera. Sample is taken by Stratified Proportional RandomSampling technique and they are 63 lecturers. Instrument used for data collectingis a questionnaire of Likert Scale model. The results of the research indicated that(1) reward influences 10% to the lecturers’ performance, (2) work motivationinfluences 12,9% to the lecturers’ performance, and (3) collectively, reward andwork motivation influence 19,1% to the lecturers’ performance. From theseresearch findings, it can be concluded that reward and work motivation are twoimportant factors for increasing the lecturers’ performance.

Diarrhea is the condition loosing too much liquid and electrolyte throughfeces and it is second biggest cause of infant death in Indonesia. Diarrhea iscaused by Salmonella sp and Escherichia coli bacteria. Inappropriate drug usedsuch as anti diarrhea and antibiotic can cause another health problem. Analternative treatment which does not cause side effect to the diarrhea victim isusing an anti microbe active of the plant medicine. One of the plant which is usedby the people as a treatment for the diarrhea victim is tea leaves (Camelliasinensis L.). it contains anti microbe active such as catecin, tannin, flavonoid andsaponin. Thus, the research was conducted to find out the minimum restrictionconcentrate of Camellia sinensis L. in E. coli and Salmonella sp.The minimum restriction concentration is used dilution method with jellyas the media (Jelly dilution method) by double it. The concentrations of E. coliare 50 %, 25 %, 12,5 %, 6,25 %, 3,125 % and 1,56 % with 10 % antibioticampicilin control. The concentrations for Salmonella sp are 50 %, 25 %, 12,5 %,6,25 %, 3,125 %, 1,56 %, 0,78 %, 0,39 %, 0,195 % and 0,0975 %. The data wasanalyzed in qualitative method by examining the minimum restriction of tealeaves extract (Camellia sinensis L.) in the bacteria that caused diarrhea. Theresearch was conducted on August 2010 in Biology Laboratory of STKIP PGRIWest Sumatera. Tea leaves was extracted in Chemical Laboratory of KopertisWilayah X Padang. The research found that E. coli is more resistant to tea leavesthan Salmonella sp. The minimum restriction concentrate of tea leaves extract(Camellia sinensis L.) in E. coli is 3,125% and 0,0975% in Salmonella sp.

Penicillin G acylase is catalysed hydrolisis enzym penicillin G to 6-amino penicilanad acid (6-APA). 6-APA is precursor to made semisintheticpenicillin. Semisynthetic penicillin derivated of natural penicillin that get it bychange natural penicillin chemistry structure or sinthesis nuclear penicillin.Penicillin G acylase (PGA) produce of bacteria but bacteria produced numberpenicillin is limited so looking new bacteria penicillin produce is importen to do.Based it haved bacteria isolation in Padang town any rivers, include air batangKandis, air batang Kurao, air batang Kuranji, air batang Arau dan air batang Arudi kota Padang. This research do in Kopertis wilayah X laboratory. Activity assayPGA used Meevootisom methode is metode easy to selection, rapid and spesifikto selection bacteria strain PGA produced. Meevootisoom metode used Serratiamarsescens, is resisten to penicillin and sensitiv to 6-APA. Result of this researchis every isolated from all rivers contain PGA.
