Abstract

Rubber (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/14

Abstract

PsPSP 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/17

Abstract

The 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: http://jurnal.polinela.ac.id/index.php/AIP/article/view/19

Abstract

National sugar requirement for direct consumption of households and industry will increase in line with population growth. The national sugar demand in 2014 reached 5,700 million tons, while national production only 3,500 million tons. The aim of research to get a way to make palm sugar liquid.  With a temperature of line and evaporation. The research was arranged in a randomized complete block design with a factorial treatment without the provision of lime and lime 0,05% combined with avaporation temperature of 70 0C, 80 0C, evaporation temperature and 90 0C, evaporation temperature. The result showed that the best result of tained in the treatment of lime with evaporation temperature of 70 C ocontent % feces 0,49,043% ash content, reduction sugar 3,75% All treatment SNI of lime meet the quality standards.Keywords: evaporation temperature, lime, liquid palm sugarPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/49
