Abstract

Dendrobium anosmum is one of natural orchids in Indonesia. Optimization of medium composition for orchid propagation through in vitro culture is necessary to enhance propagule multiplication capabilities and quality. This study was aimed to study the influence of concentration of coconut water in culture medium on in vitro growth and development of D. anosmum orchid species and to determine the optimal coconut water concentration in culture media.  The experiment were arranged in a Completely Randomized Design with four treatments and eight replications. The treatments consisted of the addition of coconut water with concentrations: 0 ml•l -1 (control), 50 ml•l-1, 100 ml•l-1 and 150 ml•l-1. The results showed that addition of coconut water in culture medium gave different effect on shoot growth and multiplication of D. anosmum orchids.  Coconut water concentration of 100 ml•l-1 was the best concentration for growth and multiplication of D. anosmum orchids, based on both shoots and roots growth, plantlet height and wet weight.

Abstract

This study was aimed to determine the proper dose of ash desiccant on maize seed stored for 30, 60 and 90 days. The design used was a Completely Randomized Factorial Design, with two factors and three replications.  The first factor was desiccant dose (D) : Do = 0 % (control), D1 = 5 % (12.5 g of seed weight), D2 = 10% (25 g of seed weight), D3 = 15 % (37 g of seed weight), D4 = 20 % (50 %g of seed weight), D5 = 25 % (62.5 g of seed weight).  The second factor was length of storage (S) : S1 = 30 day storage, S2 = 60 day storage and S3 = 90 day storage. The result show that use of desiccant only gave effect on the water content of seeds (12.31 %) and speed of seed growth vigor parameters (24.84 %).  Use of desiccant in 90 day storage were able to maintain water content of seeds (12.43 %), seed germination viability parameter (100 %), and vigor of seeds, which consisted of seed growth simultaneity (66.77 %) and seed growth speed (28.71 %).  The interaction between the use off ash desiccant and the length of storage had no effect on  viability and vigor of maize (Zea mays L) seeds but had an effect on their water content after storage (12.73%).

Abstract

Fertilization efficiency which could enhance soil productivity is determined by type, application method and appropriate dose of fertilizers.  A green house experiment to study effect of different maturity level of ela  sago bokashi and some dosage of  SP-36 fertilizer on P-uptake and growth of maize (zea mays l.) on ultisols has been performed. The experiment was set up in three-replicates factorial Randomized Block Design. The treatments were  three maturity level of ela sago bokashi i.e. 2, 3 and 4 weeks; and four dosages of SP-36 fertilizer i.e. 0, 2, 4 and 6 g/10 kg of soil. The results showed that application of bokashi regardless of their maturity at the same time with each  doses of SP-36  increased P uptake, plant height and stem diameter of maize. Giving four-week ela sago bokashi with 6 gr/10 kg of soil of SP-36 was the best treatment to improve P uptake, plant height and stem diameter of corn crop up to  0.15%, 140, 60 cm and 1.64 mm respectively.

Abstract

The use of biological agents to prevent the growth of plant diseases is aimed at decreasing the capability of particular pathogen, preventing their growth and spread, reducing the infection and intensity of pathogenic attack to main plants. Trichoderma harzianum is commonly found in almost all types of soil, and is one of fungi that can be used as biological agents to control plant pathogens.  Growth and development of this fungi are mostly influenced by factors such as temperature, light, air, and pH.  It is also dependents on other nutrients such as carbon, nitrogen and plain carbohydrate which are contained in sago waste (ela), bran and rice husk. The objective of this study is to find out the utilization of sago waste, bran and rice husk as media to multiply the biological agents T. harzianum. The result of this study showed that sago waste compost could  be used as a medium to multiply the antagonist T. harzianum; when appropriately mixed with bran and rice husk (1:1:1 v/v), sago waste composts would be an effective media to develop the T. harzianum fungus. This mixture is better compared to sago waste composts, husk, sago waste composts and bran, and sago waste composts and husk. It is doe to the fact that in the media number of spore of T. harzianum (7,08 x 109/mL) increased and colony characteristics was dense..

Abstract

One of the major constraints in chili production system in Indonesia is the fruit fly attack on chili fruits. These pests often lead to crop failure if not treated seriously. One way used to suppress the pest population is the use of Methyl Eugenol attractant compound (Petrogenol 800 L). The study was conducted to determine the effect of methyl eugenol dose and catching time difference on fruit flies that were caught. The study took place in Waimital Village, Kairatu Subdistrict, West Seram District. The research was conducted in an experiment using a Randomized Block Design (RAB) with 5 treatments, namely: (A) 0.5 ml of methyl eugenol, (B) 1 ml of methyl eugenol, (C) 1.5 ml of methyl eugenol, (D) 2 ml methyl eugenol, (E) 2.5 ml of methyl eugenol, placed in a each trap. Observations were conducted when the insects were active at 10.00 (06.00-10,00 period) and when the insects were inactive at 18:00 hours (11:00 to 18:00 period) on the number of fruit fly imagoes that were captured. The results showed that the effective methyl eugenol dose to catch Bactrocera dorsalis was in treatment C (1.5 ml, with 32.53 fruit flies caught per day or 97.67 fruit flies catches during three days of observation. The highest number of catch for 3 days was at 2,5 ml, with 118.60 fruit flies caught.

Abstract

This research was conducted to estimate the values of parameters which described the physical characteristics of catchments area and monthly water balance components, and understand the sensitivity of the water balance components to change in the parameter value due to the physical changes occurring in Way Pia catchments area, Ceram Island.  The method used involved calculation of the regional water balance in the current time (normal) and during the time of land use change, using an evapoclimatonomy model. The main model inputs were monthly rainfall, global radiation and run off. Analyses of data were conducted with five steps as follows : (1) mathematical formulation of the evapoclimatonomy model, (2) algorithm formation and transfer to computer code, (3) establishment of parameters and calibration, (4) validation of model, and (5) experimentation of model. The current physical conditions of Way Pia catchments area were characterized by: average of parameter value of albedo, a = 0,16; rainfall threshold, Pn = 100 mm; surface run off ratio, np = 0,23; evapority, ep = 0,42; measure of soil water loss from sub surface, vN = 0,12; and measure of evapotranspiration of soil water from sub surface, vE = 0,20. Model output of the current water balance consisted of  annual value of soil moisture, m = 272 mm; total evapotranspiration, E = 1393 mm, and total run off, N = 920 mm. The land use change  in the form of land clearing will increase the parameter values of a and np, which affect on increasing of direct run off (N') of 13% as compared to current conditions.

Abstract

Low quality of banana fruits due to anthracnose caused  by Colletotrichum musae fungi could be overcome by introducing anthracnose-resistent varieties. The research’s objective was to find out pathogenecity of C. musae on six local banana varieties namely Dewaka, Ambon Kuning, Abu-abu, Raja,  Empat Puluh Hari and Nona. A laboratory experiment was carried out by using completely randomized block design with six replicates. The result showed that the pathogenicity of C. musae on  six varieties of banana fruits was differ. Average incubation period of fungi and damage level of banana fruits were 3.5 days and 32.53% respectively whereas average rate of infection of C.musae was 0.115 units/day. This experiment suggested that banana var. Abu-abu was resistance to anhtracnose while banana var. Raja, Ambon Kuning  as well as Dewaka were susceptible to anthracnose. Banana var. Empat Puluh hari and Nona were classified in moderately resistance to anthracnose.
