Abstract

Analog rice is one of the solutions that can be developed to overcome the problems of food security both in termsof the use of a new food source or for diversification of food. The purposes of this study were to determine theeffect of starch as a binder in the manufacture of analog rice and to examine the properties of analog rice in thetermofmoisture content, grains diameter,water absorption, bulk density, and expantion ability. Analog ricewasperformed by using a set of analog rice grain making machine (granulator). Five different compositions ofanalog rice weremade and tested. The formulas are pure bananas flour rice (100%banana flour) and mixed ofbanana flour and tapioca flour with ratio of 95 : 5, 90 : 10, 85 : 15 and 80 : 20. The results show that the watercontent of analog rice is between 10,41%and 13,08%, water absorption range from 36,98%to 64,32%, bulkdensity of 0,766 g /cm3 to 0,794 g /cm3, and expantion ability range from5,4%to 14,4%. The addition amountof the flourmixture causes enlargement of the grain diameter.Keywords: banana flour, tapioca flour, analog rice, granulator, diversification.

Abstract

Biogas technology with zero waste concept is expected to be the alternative energy and to reduce environmental problems. The purpose of this study is to know the biogas yield per kilogram of each chicken and cow manure comparison. The study was conducted in six treatments with the addition of chicken manure of 0, 100, 300, 500, 700 and 1000 grams. The fermentation process is done using a batch system and biogas measurement was taken daily. The parameters to be observed were organic matter, the degree of acidity (pH), temperature, volume of biogas, biogas productivity, and C / N ratio of each treatment. The results showed that the overall pH at the beginning and end of the study tend to be close to neutral. The highest biogas yield was resulted from a mixture of chicken manure and cow manure at the composition of 1:1 or 50%:50% with biogas total amount of 35.690 ml and biogas productivity of 0,33 liters/g (volatile solid) . Keywords : biogas, cow manure, chicken manure, anaerobic codigestion.

Abstract

The aims of this researchwere to find out the effect of the amount of tapioca flour subtituted inwheat flour on thephysical attributes ofwet herbal noodles. The studywas analyzedwith the completely randomized designwith 4variations of substitutiontapiocawhich are 0%, 10%, 20%, and 30%with 3 repetitions for each treatment. Theresults showthat the higher the substitutionof tapioca flour, the higher thewater content and tensile strength, butthe lower thewater absorption and swell noodles. The average score of each composition in the hedonic test tendsto be on the classification dislike – neutral. Noodles with tapioca flour tend to bemore durable. The analysis ofvariance and Duncan test ( <0,05) show that substitution of tapioca significantly affects moisture content,tensile strength, and the HSI color, but tapioca substitution does not influence the water absorption and swellnoodles.Keywords : Herbalwet noodles, Food quality, Tapioca flour

Abstract

This study aims to determine saturated hydraulic conductivity (Ks) of Petung Bamboo with several treatments.This studywas conducted inMarch-May2015, intheDepartmentofAgriculturalEngineering, FacultyofAgriculture,University of Lampung. The treatments consisted of two factors; firstwas bamboo treatment andthe secondwasbamboo positions. Bamboo treatment consisted of 3 levels; both epidermis and endodermis were not scraped,epidermiswas scraped and endodermiswas not, and both epidermis and endodermiswere scraped. In the secondfactor, bamboo was placed horizontally and vertically. Based on research conducted, Ks of unscraped layers ofthe epidermis and endodermiswas 0 cm.sec-1. For the treatment of scraped epidermis and unscraped endodermis,Kswas 3.04 x 10-10 cm.sec-1. For the treatment of bamboo epidermis and endodermis layers scraped,Kswas 5.40x 10-10 cm.sec-1. Bamboohorizontally placed had higherKs than bamboo vertically placed. The resultalso showedthat bamboowith higher density had lower hydraulic conductivity.Keywords: Hydraulic conductivity, Petung Bamboo

Abstract

Biogas is a renewable or alternative energy utilizing the decomposition process of awide range of organicwastesthat generates methane gas (CH4). The purpose of this study is to evaluate the effect of the addition of coconutpulp and banana peels on biogas yield from cow dung. Parameters to be observed include: characteristics ofsubstrates, degree of acidity (pH), temperature, biogas production and biogas yield, as well as the flame frombiogas burning. This research is expected to produce an appropriate technology for treating waste of coconutpulp and banana peels into value added products and scientific information on the effect of the addition ofcoconut pulp and banana peels to biogas. The experiment design was a completely randomized design of sixtreatments,with consecutive composition of cowdung : banana peel : coconut pulp namely A50:40:10, B50:30:20,C 50:20:30, D 50:10:40, E 50:0:50, and F 50:50:0 with 3 replications. The data were analyzed by using ANOVAfollowed byDuncan test. The results showed that the additionof coconut pulp and reductionof banana peels in thebiogas composition affected pH, C/N ratio, and biogas production, but had no effect on the temperature, andbiogas yield. The increase in coconut pulp resulted in lower pH, the C/N ratio, and biogas production. Optimumcondition is the treatment with composition of 50:50:0 without the addition of coconut pulp with a C/N ratio of21,22 and pH of 5,5-6,5.Keywords: banana peel, biogas yield, coconut pulp, C/Nratio, renewable energy.

Abstract

This study aimed to determine the effect of granule growing media on growth and yield of vegetables in ahidroponic wick system. The design of this study used Randomized Complete Block (RCB) with factorialarrangement and three replications. The first factor consisted of three levels : kale (S1), spinach (S2), andmustard (S3). The second factorwere the size of the granules with four levels : 12mm (M1), 6mm (M2), 4 mm(M3) and husk char (M4) as a control. Each plant was grown in a wicked pot. There were 12 treatmentcombinations, with three replicates. Parameters observed were physical properties of the media,evapotranspiration, number of leaves, growth, biomass, and yield. Data was analyzed using the Analysis ofVariance (ANOVA) 1%and 5%levels of significance, followed by LSDcomparision. Results showed that therewasno significant interaction betweenmedia and types of plant. However; sizes of media significantly affected theevapotranspiration, growth, biomass, and yield.Keywords:Wicked, hydroponics, granules, media, vegetables

Abstract

All this time, efforts to improve soybeanproductivity is still based onthe expansion of planting area (Badan PusatStatistik, 2013), but production is still declining. It is also influenced by the lack of understanding about thecultivation of soybeans and the price is less promising causing farmers are reluctant to plant soybeans. Thisresearch aims to investigate the response of the growth and productionof two varieties of soybean (Glycinemax.(L) Merrill) to some degree of available soil water depletion. This research was conducted at the Laboratory ofIntegrated Courses Faculty of Agriculture, University of Lampung, in May up to August 2014, using factorialdesign in a completely randomized designwith the first factor is depletion of groundwater available (P) which iscomposed of four levels of available soilwater depletion treatment (ATT) is the treatment P1 (0-20%),P2 (0-40%),P3 (0-60%), and P4 (0-80%) and the second factor, namely soybean varieties (V), which consists of varieties V1(Wilis) and V2 (Kaba), with three repetitions. Results were analyzed by F test at LSD further by 5%and 1% byusing Statistix8 Program. The results showed that the effect of the level of available soilwater depletionduring thevegetative stage and generative phase did not significantly affect plant growth and crop yield. The highestproduction yield andWilis varieties Kaba obtained at a rate of 0-40%thinning. Based on these values concludedthat to produce optimal production in both varieties can still bemaintained until the level of depletion of availablesoilwater content to 40%.Keyword : Available SoilWater,Depletions, Generative Phase, Vegetative Phase, Yield.
