Abstract

Production of kenaf fiber for industry mostly uses chemical fertilizers with synthetic dyes that will also cause health and environmental problems and adversely affect all life forms. Increased health and environmental concern make organic kenaf fiber production with natural dyes highly recommended for both handicrafts and for industrial scale because natural fertilizers and dyes are non-toxic, decomposable, and environmentally friendly. The purpose of this study is to determine the level of consumer preference to organic kenaf fiber with natural dyes. The study used a two-factor group randomized design with the first factor of organic kenaf fiber and a second factor of natural dye consisting of 3 levels. The research was repeated as many as 2 replications so that there were 6 experimental units. Variables observed by consumer's level of craft product from organic kenaf fiber with natural dye covering color, texture and odor tested. This test is done by Hedonic Test method, using questionnaire with untrained panelist (consumer) as many as 40 people with data obtained based on a panelist response using a hedonic scale was analyzed by Kruskal-Wallis test. The results showed that there was no significant difference in consumer preferences for the color, texture and odor of organic kenaf fiber with various natural dyes.

Abstract

Gladiolus is a potential ornamental plant to be widely developed because its high aesthetic value. Generally, gladiolus is propagated vegetatively by using tuber that called corm. There are some problems in gladiolus vegetative propagation, which is corm has a dormancy period and produces only one to two corms for each gladiolus plant. The effort that can be done to solve these problems is to provide benzyladenine to gladiolus corm. This study aims to determine the response of four varieties of gladiolus (Gladiolus hybridus L.) that soak to benzyladenine in increasing the growth of shoot and corm production. This research was conducted in Bandar Lampung in 2017. The treatment was designed factorially (4 x 4) using Randomized Block Design. The first factor was the varieties of gladiolus ie Anisa, Clara, Nabila, and Nurlaela. The second factor was the 100 ppm concentration of benzyladenine in repeating ie first, second, third, and fourth soaking. Data analysis was tested by Least Significant Difference (LSD) test at 5% level. The results showed that (1) from four gladiolus corm varieties, Nabila produced the highest number of shoots at 10,34 shoots, while the variety that produces the highest number of corm was Clara at 5,71 corms, (2) the benzyladenine that used up to four times for soaking the corm resulted the same response in increasing growth of shoot and corm production of four gladiolus varieties, (3) the response of each gladiolus varieties didn’t depend on how many times that benzyladenine used to soak the corm in increasing the growth of shoot and corm production of four gladiolus varieties.

Abstract

Most of the coffee production areas in Lampung are in the vicinity of production forests andprotected forests, also a catchment area for watersheds in Lampung, namely Sekampung andWay Seputih watersheds. Continuity of sustainable coffee production lines is an importantdemand that needs to be done. The application of coffee production systems with shade(agroforestry) in the catchment area is very important in ensuring environmentalsustainability. This study aims to analyze the income performance of agroforestry coffeebased on the land status in Hulu Das Sekampung. The research uses survey methods. Fielddata exploration conducted in April-November 2016 is located in Datar Lebuay and SinarJawa Villages. Air Naningan, Tanggamus, Lampung. The descriptive statistical analysismethod is used to explain the performance of agroforestry coffee production at the researchlocation. Based on the results and discussion it was concluded that farmers with landownership status had the highest level of coffee farming income compared to the land statusof HKm and non-HKm. Agroforestry coffee farmers obtain sources of income from coffeeproduction, MPTS production, and other crop production (multiple cropping). The averagecontribution of coffee farming income is 22% of the total farm income. Coffee contributes22% to the total income of farmer households. Farmer's household income with the status ofland ownership is the highest compared to the land status of HKm and Non-HKm. Thediversity of income sources of upstream farmers in the watershed. The villages that comefrom various vegetation plants are important in maintaining land cover as a catchment area.The practice of agroforestry coffee is an adaptation of sustainable production in the upperwatershed Sekampung. The pattern of agroforestry coffee production in the area aroundprotected and watershed forests needs to be continuously developed.

Abstract

Reduced productive rice fields to non-paddy fields, most possible extension of the nationalrice cultivation area to the suboptimal lands reaching ± 91.9 million ha. Technologypackages that can be applied include the use of new improved rice varieties through theassembling of varieties that have high yield potential, resistant to suboptimal soil stress. Theobjective of the research is to produce new superior rice varieties that are available invarious environments. The study used a split-plot design, as the main plot is an environmentconsisting of rice paddies and gogo, as a subplot is the genotype of rice. The treatment ineach environment is prepared using the Randomized Complete Block Design (RCBD). Thetreatment consisted of 10 new rice strains and four varieties as a comparison. Variablesobserved (1) plant height; (2) the maximum number of shoots; (3) number of productiveshoots; (4) long panicle; (5) the number of grains per panicle; (6) the amount of graincontent of each panicle; (7) the number of empty grains per panicle; (8) weight of 1000grains of grain; (9) grain yield of each clump; (10) grain yield per hectare. Data wereanalyzed by variance if there was a difference between mean, median treatment, followed byLsd test at 5% level. The adaptability and yield stability of each strain was determined basedon the value of the coefficient of diversity (KK) (Francis and Kenneberg, 1978) in Syukur etal., (2012). The results showed that seven new rice strains had adaptations both planted asupland rice and lowland rice, namely strains B3, B4, F2, F3, H1, H4, and L2.
