Abstract

The peak production of BPM 24 clone rubber  was reached in the 7th to 10th year, but production quickly declined to reach its lowest point in 15 years. Stimulants are technologies used to increase production. Stimulants generally contain ethylene. Ethylene affects the balance of sucrose in latex formation and also increases metabolic activity in latex vessel cells. The purpose of this study is to know the physiological character response of rubber plants (hevea brasiliensis Muell. Arg) clone BPM 24 against the application of organic ethylene stimulant banana peel. The research was conducted in september to november 2019 at the research center of rubber experimental garden Sumbawa in Palembang, South Sumatra. This research method is descriptive with treatment: without stimulant, ethrel 10 PA, banana peel Ambon concentration 333 g/L, banana peel Ambon concentration 500 g/L, banana peel Ambon concentration 666 g/L, banana skin wax concentration 333 g/L, banana skin wax concentration 500 g/L, banana skin wax concentration 666 g/L, banana peel Kepok concentration 333 g/L, banana peel Kepok concentration 500 g/L, banana peel Kepok concentration 666 g/L. Observations are carried out on physiological character (thiol levels, inorganic phosphate levels, sucrose levels and dry tapping grooves. The treatment of banana skin stimulant is able to increase the production of latex without interference in the physiological character of the plant, but the use of stimulants with excessive and inappropriate doses can lead to the onion of dry tapping grooves.

Abstract

Sub soil is soil under the top soil layer, with low fertility. The use of sub soil as an Arabica coffee seedling planting media needs to be considered because the top soil layer has been much reduced by erosion or run off. Needs modification in sub-soil soils to increase fertility. Increased sub soil fertility can be done using organic materials, both solid and liquid. Coffee seedling using the right planting media will determine the growth and production of coffee in the field later. The purpose of this study was to determine the use of subsoil growing media with the addition of organic material for the growth of Arabica coffee seeds. The experiment was conducted at the Ciparanje Experimental Field, Faculty of Agriculture, Padjadjaran University, Sumedang Regency, in March to June 2019 with altitude of ± 780 meters above sea level. The experiment used a randomized block design (RBD) with 9 treatments repeated three times. The treatments are as follows: 100% topsoil; subsoil 100%; topsoil: chicken manure (2: 1); subsoil: chicken manure (1: 1); subsoil: chicken manure (2: 1); subsoil: chicken manure (3: 1); subsoil + 25% coconut water; subsoil + 50% coconut water; subsoil + 75% coconut water. The results showed that the modification of subsoil with the addition of organic matter affected the growth of Arabica coffee seedlings on stem diameter variables of 8 MST and leaf chlorophyll index of 16 MST. Subsoil media with the addition of chicken manure (3: 1) had a good effect on leaf chlorophyll index and subsoil media with 25% coconut water had a good effect on the diameter of Arabica coffee seedling stems. Subsoil can replace topsoil by adding organic matter.

Abstract

In order to properly grow, cocoa seedling requires adequate nutrients. In a usual practice nutrient in the form of 2g of urea is given once every two weeks. The source of nutrition for cocoa seeds can come from organic materials such as coconut water. Coconut water contains nutrients and growth hormones. The purpose of this study was to determine whether coconut water could be used to fulfill the nutrition of cocoa seedling through different application methods and intervals expressed by plant dry weight. The experiment was conducted from October 2019 until February 2020 in Ciparanje experimental field, Universitas Padjadjaran, Jatinangor with the altitude of 760 meter above the sea level. Experimental design used was randomized block design (RBD) with nine treatments and each treatment was repeated three times. The treatments consisted of control (urea 2 g every 12 days), coconut water application towards plant every 3, 7, 14, 21 days, and to the soil every 3, 7, 14, 21 days. The results of the experiment showed that there was no effect of coconut water application in different methods and intervals on shoot dry weight, root dry weight, shoot root ratio and leaf area of cocoa seedling, therefore coconut water can be used as an alternative source of nutrition for cocoa seedlings.
