Abstract

The duration of submersion and the level of acid concentration which are the decisive factors to succed the chemical scarification. The duration of submersion should be adjusted to the level of seed skin thickness, the level of acid concentration and the type of acid used. This study aimed to analyze the inmersion effect of kemiri sunan seeds in sulfuric acid solution to break the seed dormancy and to get the most effective time of submersion in order to break the dormancy of kemiri sunan seed. The experiment was conducted in the greenhouse for 2 months (62 days). The randomized complete design was employed as experimental method. There were 4 treament tested, i.e : (1) control (without immersion in H2SO4 solution); (2) immersion in H2SO4 solution for 10 minutes; (3) immersion in H2SO4 solution for 20 minutes and (4) immersion in H2SO4 solution for 30 minutes. The results of research showed that control gave the best results in term of the percentage of germination (G), mean daily gremination (MDG), and germination rate (GR).

Abstract

The study aimed to analyze physiological responses of soybean varieties Grobogan to different shade levels, including changes in amount of leaf total protein content, photosynthetic pigments content, index stomata and stomata gap width and vegetative growth. The research was conducted using a Completely Randomized Design (CRD) one factor, that is shading level with three treatments: no shading, 50% shade and 70% shade. Data were analyzed by ANOVA and continued by DMRT at 95% confidence level. The results showed that Soybean varieties Grobogan is able to adapt and survive under 50% and 70% shade. Varieties Grobogan responded to increased shade by increasing leaf total protein content and photosynthetic pigments content and decreasing index stomata and stomatal gap width. Shaded plants showing stunted vegetative growth, seen by decreased of leaf number, leaf area, leaf thickness, stem height, stem diameter, root length and plant weight.

Abstract

In vaname shrimp cultivation system, bacterial disease is a problem that often arises that mainly caused by the bacteria Vibrio sp. Sinbiotic application is one way to prevent disruption of the disease. Sinbiotic is nutritional supplements that made from the combination of probiotic and prebiotic that can provide beneficial effects to the host. This research uses a local sinbiotic of probiotic bacteria Bacillus sp. D2.2, which comes from the traditional ponds in the Mulyosari village, Pasir Sakti district, Lampung Timur Regency, Lampung. Prebiotic that used in this research made from meal extracts of purple sweet potato that had the best capability to support the growth of bacteria probiotic Bacillus sp. D2.2. This research aims to know the effectivity of sinbiotic against the infection of vibriosis againts to vaname shrimp by doing analysis of clinical symptoms and tissue damage post test challenge using bacteria Vibrio harveyi. The results showed that addition sinbiotic gave effect to SR 6,25 %, MTD 13,80 hour, and clinical symptoms and then tissue damage is lower than without the feeding of sinbiotik.

Abstract

Teak is the forest species with the highest economic value in Indonesia. It is especially important to many villages in Maluku Province.In order to manage for maximum profitability we need to first understand the pest species attacking this valuable tree species and to determine how much damage is caused. species were identified, and the intensity of pest attack determined.We identified two species acting as major pests;the lady bug , (Coccinella magnifica) and the snoutbeetle(Orchidophilus aterrimus ).The snout beetleand the lady bug were associated with severe damage on 64% and 56% respectively of the trees sampled although the intensity of damage was low to medium

Abstract

Fish have good prospect to be developed because have high economic value. However, the percentage of bacterial fish diseases reached 33.9%. Tilapia (O. niloticus) is one of the most common bacteria. The TPC results of tilapia ponds of I, II, and III cultivation are 1.32 X 105 Cfu/g; 1.7 X 105 Cfu/g; 1.14 X 105 Cfu/g. From the results of physics measurement parameters of three ponds cultivation is still in accordance with the classification of water quality, but if viewed from the results of chemical measurement parameters pond culture II pertained water polluted.

Abstract

This research aims to determine the best depth of the development of seaweed seeds produced by tissue culture. The trial was carried out for VI weeks using the same initial weight of seeds which was 75 grams on 3 levels of different water depths: 10 cm, 30 and 50 cm. Parameters observed included plant development, and survival rate. The results of observations of plant development at a depth of 10 cm from the first week to the week to VI the initial weight of 75 g, 115.80 g, 157.40 g, 216.00 g, 303.00 g, 341.00 g and 375.00 g. 30 cm depth initial weight 75 gr, 118,60 gr, 139,80 gr, 199,00 gr, 254 gr 293 gr and 304 gr. 50 cm depth: initial weight 75 gr, 96,6 gr, 122,4 gr, 159 gr, 207 gr, 250 gr and 260,8 gr. Survival rate (SR) at a depth of 10 cm from the first week to the fourth week was 100% and at the fifth and sixth weeks 98% respectively. SR at a depth of 30 cm from the first week to the fourth 100% and the fifth and sixth weeks 96%. And SR at a depth of 50 cm from the first week to the fourth week 100% and at the fifth week 94% and 92%. Based on the results of calculations, the development of plants at a depth of 10 to 30 cm, is relatively the same and gives better results than at a depth of 50 cm. This means that in conducting production activities can be planted at a depth of between 10 to 30 cm.

Abstract

This research aims to analyse the variation on morphometric and cytochrome b (cyt b) DNA mitocondria gene of Ompok hypopthalmusin Batang Hari river. Cyt b DNA mitocondria gene was amplified by polymerase chain reactionand targeted1104bp nucleotids. The results show there is no significant differentiation on morphometric structure of the samples. This result is consistent for both of morphometric (p=0.96) and index (p=0.99). Amplification of cyt b DNA mitocondria gene generates927 bp nucleotids with cytosin as the majour component and guanin as the lowest. Only one nucleotide(0.11%) is vary among all the sequences i.e.883thof the partial cyt b gene. The 883th nucleotidein O. hypopthalmus Simpang and Sungai Bengkal is guanin, while inMandiangin dan Pelayangan is adenin. This subtitution occured on the first codon and changed the 295th putative amino acid ofcyt b gene. The putative amino acid in O. hypopthalmus Simpang-Sungai Bengkal is alanina (GCC), while inMandiangin-Pelayangan is treonina (ACC).

Abstract

This study aims to determine the optimal concentration of Bacillus licheniformis required in the formation of liquid sugar from cassava waste, the value of sugar and value starch contained in degraded cassava skin waste. The design used in this study was Completely Randomized Design (RAL) with 4 treatment concentration of cassava leaf extract (Manihot utilissima Pohl.), Ie 0 concentration, 1.5 ml concentration, 2.5 ml concentration and 3.5 ml of concentration B. licheneformis. Data were analyzed using analisis (ANOVA) followed by Duncan's range test (DMRT) with a 5% confidence level. The results of the study showed that all treatments had a significant effect on the administration of B. licheniformis concentrations. Treatment using 1.5 ml B. licheniformis concentration on cassava skin substrate weighing 1 gram after Duncan's test range (DMRT) with 5% confidence level resulted Reduction sugar value of 6.07%.

Abstract

Indole Acetic Acid (IAA) is an important that could improve plant growth. Actinomycetes is one group of bacteria that could produce IAA. The purpose of this study was to examines the potential of actinomycetes from Siak, Riau Peatland in producing IAA the effects to red pepper (Capsicum annuum L.) germination. The result of this study was collected 21 isolates of actinomycetes which able only to produced IAA in SCB (Starch Casein Broth) medium with tryptophan addition. The produce highest IAA in L225 isolate with concentration 37,70 ± 1,00 µg/ml by medium SCB with typtophan addition. 14 isolates gave respons for length of sprouts parameters and 20 isolates gave effect to the root length parameters for red pepper seeds with incubation for 15 day.
