Abstract

Natural latex is an agricultural product that has a lot of benefits human needs. The efforts to increase latex production have to be continually done in order to meet the requirement. Paying attention to the time of latex taking and giving latex stimulant treatment are the important efforts. Both the efforts have to be taken care very well to prevent the damage on the coutchouc. The objective of the study is to know the effect of applying ethepon and the time of latex taking to word latex production on the coutchouc and the interaction between both of the factors. The research took place in Dharma Agung Village sub-distric of Seputih Mataram, Central Lampung regency on May—July, 2013. The ingredients used in the research are: coutchouc clone PB 260, ethepon with Cepha 100 PA brand (1,5% and 2,5% of concentration), acetic acid and aquades.  The research is in factorial pattern which is arranged in complete randomized block design by three repetitions. The first factor is the application of ethepon (A) divided into three treatments: non ethepon application (a1), ethepon application with 1,5% concentration (a2), and ethepon application with 2,5% concentration (a3). The second factor is the time of latex taking (T) at 05.00 a.m. (t1), at 07.00 a.m. (t2), and at 09.00 a.m. (t3). Based on the finding of the research, it can be concluded that the use of ethepon with 2,5% concentration and the earliest time latex taking (at 05.00 a.m.) produce the highest amount of latex than others treatments.Keywords: Latex, Ethepon, Latex Taking Time

Abstract

The growth of caoutchouc seed by applying gibereline hormone in various concentrations and chicken manure in various dosages (Krisnarini). The application of ZPT gibereline in various dosages gives the same influence in the growth of caoutchouc seed which is supported by all the observation variables, the mixture comparison of chicken manure: soil (2:1) gives the tallest result of caoutchouc seed’s growth which is supported by the height of caoutchouc seed, root volume, dried shoot mass and dried root mass variables.Keywords: Caoutchouc seed, Gibereline and chicken manur

Abstract

The study was conducted in Central and East Lampung District with consideration for soil fertility in rice fields are planted with rice tends to go down, so that the harvest of dry grain production leveling off. The method used is a survey method, including primary data collection through interviews using questionnaires. Identification of using soil conditioner collected to reveal information about the type of soil conditioner that is known farmers and types soil conditioner once used by farmers. The aim of this study were: (1) an inventory of the type soil conditioner known and used by farmers, as well as the resources and applications dose; (2) determine the benefits and constraints use soil conditioner at the farm level, (3) to know fertilizer efficiency at the farmer level as the impact of soil conditioner utilizing, (4) to study soils conditioner prospect to increase land productivity. The results showed that the organic matter, soil conditioner types known and used in Central Lampung District is Zeolite Agro 2000, ZP.30 (enrichment zeolit with P nutrient) and dolomite, whereas in the East Lampung District is a regular zeolite and dolomite. The use of soil conditioner in both districts useful addition to increasing the production of rice crop about 10-30%, also improve soil fertility and increase the efficiency of nutrient uptake of inorganic fertilizers.
