Abstract

Obstacles factor to get natural rubber raw materials is less efficient for latex processing into concentrated latex, because it need a long time that 2-3 weeks. Centrifugation method many used by concentrated latex factory because it can concentrate the latex with a short relatively time. While the weakness of the centrifugation method is more expensive if that  compared with the curdling. With the weakness centrifugation method and curdling, in this research, making the concentrated latex are used  vibration method, with the addition of curdle. The purpose of this research is to get the optimum vibrations speed for the concentrated latex manufactured, the speed of the vibrations are used 150 rpm, 175 rpm, 200 rpm, 225 rpm and 250 rpm. The design are used in this research is Randomized Block Design with 6 treatments was repeated 4 times, then obtained 24 units of the experiment, if there is a real difference, then used the BNT at the level of 5% and the data analysis process using Minitab version 16. the most optimum RPM are used in this research is 225 with a quality approaching the standard.   Keywords: latex, concentrated latex, vibration, cmc

Abstract

Agroindustry tea smallholder who still survive until now in the area of Bandung Regency, namely agroindustry tea small holder Farmer of Group Barokah in the Village of Lebak Muncang, Subdistrict Ciwidey. This agroindustry persisted, although experiencing various problems, among others: a) have not received help from the government for the factory, the processing machine is limited, b) the lack of supply of raw materials, c) unmet condition of factory hygiene, d) no SOP (Standard Operating Procedure) written, e) the distribution of products is limited, f) marketing is not yet wide, and g) the presence of new competitors who buy raw materials higher. The purpose of this study is to describe several factors determining the sustainability of agroindustry tea small holder. The research technique was conducted through case study. The determination of informant is done purposively that is: staff of the department of agriculture, vice chairman of Farmers Group, manager agroindustry tea folk, farmer suppliers. Secondary data is collected from: documents in related institutions and journals. Data and information obtained were analyzed descriptively. The results showed that several factors determining the sustainability of agroindustry tea small holderGroups of Farmers Barokah is:  a) good product quality, b) the existence of grading process, c) the availability of raw materials continue, because the form of farmer, d) workers with a solid sense of family, e) finance is able to hire employees and buy raw materials in cash, f) customer loyalty, g) areas supportive for tea business activities, and h) promotional assistance from local government.   Keywords: case study, standard operational procedure, tea business

Abstract

This study aimed to obtain the effective dose of isopropylamine glyphosate herbicide for controlling weeds in oil palm plantation andto study the change of weed composition after glyphosate application in early producing oil palm plantation.The research was conducted in smallholder oil palm plantation located in Srimulyo Kenanga Sari Village, Seputih Surabaya Sub-district, Central Lampung Regency and Weed Science Laboratory of Agriculture Faculty, Lampung University from November 2017 to January 2018. This research used randomized block design (RBD) with 4 replications and 7 treatments of 5  isopropylamine glyphosate herbicide doses (1.080, 1.440, 1.800, 2.160, and 2.520 g.ha-1), mechanical weeding, and control. The data homogeneity tested by Bartlett test, the data additivity tested by Tukey test, and the difference of median value tested by the Least Significant Difference (LSD) at 5% level. The results showed that all of isopropylamine glyphosate herbicide doses were effective in controlling total weeds, grassy weeds (Axonopus compressus, Ottochloa nodosa, Imperata cylindrica) and nutsedges (Cyperus rotundus) for 4—12 weeks after application (WAA) and broadleaf weeds (Praxelis clematidea) for 4 WAA. Glyphosate application changed weed composition at 4, 8, and 12 WAA of observations from grassy weeds to broadleaf weeds.   Keywords: composition, efficacy, herbicide, glyphosate, oil palm, weeds

Abstract

Armyworm (Spodoptera litura F.) is one of the important polyphag leaf pests that attacks almost all crops. The objective of this study was to determine the effect of various concentrations of bioinsecticide made of dioscorea tuber and aegle fruit extract on larval mortality. The research was conducted at the crop laboratory, Lampung State Polytechnic since October 2017 until December 2017. The experimental design is a completely randomized design with six treatments and four and replications. The parameters observed is mortality of armyworm larvae, which would then be analyzed using fingerprint of different varieties. That result showed that dioscorea tuber and aegle fruit extract has affected on larval mortality armyworm. Pure (100%) dioscorin tuber extract exhibited the highest larval mortality.   Keywords: aegle fruit, botanical insecticide, dioscorea tuber

Abstract

Efforts to produce good quality cocoa seedling in quality and quantity, ie the use of planting media containing nutrients needed by plants. Topsoil and cocopeat combination are expected to increase the growth of cocoa seedling. The purpose of this study was to to obtain a good soil layer medium planting on the growth of cocoa seedling, to obtain optimum cocopeat on the growth of cocoa seedling, and to obtain the interaction of soil layer medium planting and cocopeat on the growth of cocoa seedlings. This research was conducted in Politeknik  Negeri Lampung’s Teaching Farm in January 2017 until June 2017. The experiment was conducted by factorial randomized block design with two factors and each treatment combination was repeated 3 times. The first factor consists of two levels and the second factor consists of four levels. The first factor, namely top soil and sub soil. The second factor is composting cocopeat on planting medium consisting of 0% cocopeat and 100% soil, 25% cocopeat and 75% soil, 50% cocopeat and 50% soil, 75% cocopeat and 25% soil. The results showed that the cocopeat 0%-75% gave the same effect on the high varieties of seedlings, stem diameter, number of leaves, total dry weight, and dry root weight. In general, top soil and sub soil medium planting did not affected on the growth of cocoa seedling and cocopeat did not affected on the growth of cocoa seedling. There was no interaction between media layer of soil and cocopeat in all observation variables.   Keywords: cocopeat, cocoa seedling, sub soil, and top soil

Abstract

Cotton plants belong to the family Malvaceae with the genus Gossypium. The genus Gossypium is very large containing 50 species. Balittas Malang has a collection of cotton germplasm, about 662 accessions consisting of 642 accessions of G. hirsutum, 14 accessions of G. barbadense, 3 accessions of G. arboreum, and 3 accessions of G. herbaceum. In addition to its ability as a producer of fiber, its seeds can also be utilized as a source of oil and is a secondary production. The purpose of this study was to measure and estimate the genetic diversity of cotton germplasm based on the character of superior quality and quantity of cotton seed oil from several cotton plant genotypes and determine which cotton plants have good quality and quantity of cotton seed oil which is subsequently used as breeding sources & national cotton development elders. To achieve this goal, the experiment was conducted with the experimental method Randomized Block Design (RBD) consisting of 2 replications, 22 germplasm accessions as treatment, and 5 samples in each genotype. The observational parameters are the parameters of oil content quality, oil boiling point, oleic content, and linoleic content. Then the cluster analysis shows that there are 3 cluster analysis groups. Extensive genetic diversity will be beneficial in developing better quality and quantity of cottonseed oil, namely in accession of CRISS-665, CRISS-667, and KANESIA-14 which contribute more than accession of other cotton germplasm to the maximum value of quantity and quality parameters cotton seed oil.Keywords: agronomic evaluation, G. barbadense, G. hirsutum, phenotypic data analysis
