Pengaruh Dosis Enzim Papain terhadap Rendemen dan Kualitas Virgin Coconut Oil (VCO)
Full text linkVirgin Coconut Oil (VCO) is the coconut oil that is produced naturally without chemicals and heating process. Papain enzyme is a protease that is used in the fermentation of milk serves as a catalyst in the manufacture of the VCO. The main of the research is to determine the dose of enzyme papain that can produce the highest yield of VCO and determine the effect of papain enzyme dosage on the quality of the VCO. This research used a randomized block design (RBD) by using the enzyme papain treatment 0%, 0:03%, 0:06%, 0:09%, 0:12%, and 0:15% and it was repeated for three times. The result of the study treatment dose is 0.15%. The enzyme papain produces the highest yield of 31.53%. Based on the BSN about the quality standard ISO VCO No.7381: 2008 include moisture content, free fatty acids, color, and aroma of the VCO papain enzyme. And the result of the treatment did not affect the quality of the VCO.Keywords : fermentation, papain enzyme, VCOPermalink:Â http://jurnal.polinela.ac.id/index.php/AIP/article/view/2
Penggunaan Asap Cair dan Arang Aktif Tempurung Kelapa pada Mutu Karet Krep
Full text linkoai:ojs.jurnal.polinela.ac.id:article/14Rubber (Hevea brasiliensis Muell. Arg.) is one of important agriculture comodity on Indonesia. Wide area of Indonesia rubber agriculture on 2013 are 3,5 million hectares. With 3,2 million tones production maked Indonesia at second level ocupasi because low quality of block rubber. This research objective are getting liquid smoke dosage and active carbon as latexs coagulant. Research used randomized completely block design (RCBD) with 12 treatments and repeat 3 times. Liquid smoke dosage with 1:1 dilution and 2,60 pH are 6%, 8%, 10% and active carbon dosage 1% and 2% with formiat acid as a control. Latek coagulating process rubber production and rubber crepe quality testing suitable with SIR did in procesing factory and SIR quality testing laboratory Way Berulu PTPN VII, Pesawaran, Lampung. This research carried out November 2014 until January 2015. The results of this research showed more high liquid smoke dosage and active carbon from coconut shell can effect time of lateks coagulation fasier in 4,8 minutes. More high dosage of liquid smoke and active carbon treatment effected decrease of PRI and increase of latex waste level, dust level and evaporate substance level. Liquid smoke with 1:1 dilition and active carbon from coconut shell as latex coagulant showed dust level higher, so the latex are not suitable with SIR. The higher value because tar composition of liquid smoke from coconut shell.Keywords: active carbon coconut shell, liquid smoke, rubber crepe qualityPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/1
Pengaruh Konsentrasi Stimulan dan Intensitas Sadap pada Produksi Lateks Tanaman Karet Seedling (Hevea brasiliensis Muell. Arg.)
Full text linkThe lacks of national latex productivity caused by most of rubber trees (85%)managed by folks plantations which have low productivities. Good management and performance of cultivation needs for increase latex productivity, mainly in tapping process. The purpose of this research was to study about effects of ethepon stimulant application on seedling rubber trees,determine the proper tapping intensity, and to find out interaction between stimulant applications with tapping intensitytowards seedling rubber trees.The study have been done during 3 months from September to November 2014 using Randomized Complete Block Design (RCBD) factorial with 2 factor. The first factor wasstimulant concentration (C) with 2 stage, C0 = without stimulant application and C1 = stimulant application as recommended rate. The second factor wastapping intensity (I) with 3 stage. I1= once every two days, I2= once every 3 days, and I3= once every 4 days.Thus obtained 6 treatment combinationwith 4 repeats. The study result shows that the latex and dry rubber production towards seedling rubber trees could be increased by stimulant application, tapping intensity did not give effect on increasing latex volume and dry rubber production, and there is no interaction between stimulant applications with tapping intensity.Keywords: latex production, seedling rubber trees,stimulant, tapping intensityPermalink:Â http://jurnal.polinela.ac.id/index.php/AIP/article/view/1
Analisis Faktor-faktor Adopsi Metode PsPSP pada Penanggulangan Hama Penggerek Buah Kakao (PBK) di Pekon Kuripan
Full text linkPsPSP method is cultural technique of cacao cultivation for handling Cocoa Podborer (Conopomorpha cramerella Snell.), but less aplicated by farmers in Lampung Province. The research objective are investigated the adoption level and analyze influence factors toward PsPSP method of the cacao farmers adopted in Pekon Kuripan, Kecamatan Limau, Kabupaten Tanggamus. The research used survey method. Responder determined through randomized by taking 40 people of cocoa farmers. The research was carried out on October until November 2014. Scoring system is an instrument to analyze adoption level and Multiple Linier Regresion to analyse the influence factors of PsPSP method. Based on the result of interview used questioner known that the adoption level of cacao farmers are still less than average value. Self inside factors (age, education level, cultivation experiences) and outside factor of farmer (elucidation intensity) are significant toward adoption level of PsPSP method. Wide area of farm and quantity of responsibility family are not significant toward adoption level of PsPSP method.Keywords : cocoa podborer, method adoption, PsPSPPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/1
