Abstract

The zebra dove (Geopelia striata) has been a long-time favorite of many people for bird-keeping and birdsong competition which are common pastimes in Southeast Asia. The diversity of zebra doves below the species level still needs to be investigated in terms of breeding, projecting the development of internal or external bird-keeping markets, and conservation for populations in the wild as potential damage-control of the captured bird market. This study aimed to study the morphologically significant differences between the main groups of zebra doves (Local, Bangkok, Cemani Majapahit, Cemani, and Golden) and certain coat colors (silver, mocca, white striated, white cotton, cream, and black) which are traded in Special Region of Yogyakarta. The research was divided into two stages, namely surveys to breeders and hobbyists and morphometric and qualitative data collection, namely color. The results of the morphometric measurements of each individual were then grouped using SPSS Statistics and the Unweighted Pair Group Method with Arithmetic (UPGMA) method to determine whether the variables tested are significantly different. To see the clustering and distribution of the tested variables, Principal Component Analysis was performed. The results obtained show the amount of overlap in the scree plot, this proves that there is no significant difference between the race and color variants of zebra doves grouped by traders in the Special Region of Yogyakarta.

Abstract

Axonopus compressus (Sw.) Beauv. is a type of weeds that grows invasively and wildly. The weeds growth can be controlled by applying bioherbicides. The leaf extracts of Wedelia trilobata, Achasma walang, and Ageratum conyzoides produce allelochemicals that can be used as bioherbicides. The study aims to determine the effects of applying bioherbicides from the leaf extracts of W. trilobata, A. walang, and A. conyzoides on the morphology and stomata of A. compressus weeds. This study was done by: 1) making the leaf extracts W. trilobata, A. walang, and A. conyzoides with each concentration is 10 ppm, 25 ppm, and 50 ppm; 2) giving the leaf extracts treatment on the growth of A. compressus weeds; and 3) making observations on the morphology and stomata of A. compressus weeds. The results showed that there were morphological transformations on the A. compressus weeds after applying the bioherbicides. The transformations were seen in the changing color of the leaves, the reduced leaf size, and the increased number of chlorotic leaves. Meanwhile, the effects of applying the bioherbicides on the stomata of A. compressus weeds were also found, i.e. in the changing size of stomata, and the increased of stomatal index and density.

Abstract

Gatul fish is one abundance of freshwater introduced fish that can be found in all tropical and subtropical area. One species of Gatul fish has been found in Telaga Sari, Pasuruan Regency is Xiphophorus hellerii. This fish are live bearers, dimorphism sexual, modification of anal fish called gonopodium and pregnant & birthing female. Until now, its potential as a food resource is not known. This research aimed to analyze nutrient contents of Gatul fish as food resources based on the protein and fat content and to evaluate the food safety based on the content of plumbum, cadmium, and mercury. The sample of Gatul fish was collected from Telaga Sari based on four Xiphophorus helleri (female and male). The protein content was analyzed using Kjeldahl method, while the content of fat was analyzed using soxhlet method. In addition, the level of plumbum, cadmium, and mercury in the flesh Gatul fish were tested using atomic adsorption spectroscopy (AAS). The results showed that both of the flesh Gatul fish (male and female) contained high protein for orange male (20.389±0.238); orange female (20.256±0.07); gray male (21.3557±0.25), and gray female (20.5687±0.10) respectively. The fat of flash Gatul Fish both male and female content in Gatul fish ranged from 2.966%-3.934%. It seems that the nutrient content outweighs the content of others commercial consumed fish. The content of plumbum in the flesh fish were 0.712±0.0116 ppm; chadmium were 0.128±0.129, Meanwhile, the content of mercury in the flesh fish were 0.0039±0.0017. These numbers are considerably lower that the level permitted. Hence, it can be concluded that Gatul fish has potency as a cheap, safe, and nutritious of food resource

Abstract

Foliage from gardens or parks is biomass whose organic fraction can be decomposed. Foliage can be utilized by converting it into bioethanol. Various studies have shown that Trichoderma viride and Zymomonas mobilis play a role in the production of bioethanol from biomass, but until now there has been no report on the production of bioethanol from foliage using a mixture of  T. viride and Z. mobilis. The purpose of this study was to determine the optimal SSF temperature and time for bioethanol production from foliage using T. viride and Z. mobilis. The fermentation process used the Simultaneous Saccharification and Fermentation (SSF) method with a mixture of T. viride and Z. mobilis with a composition of 5% : 5% (w/v). SSF was carried out at several variations of time and temperature, 60 hours, 72 hours, 80 hours and 96 hours for times and temperatures used are 32oC, 35oC and 38oC. The fermented bioethanol was purified by distillation and finally, the ethanol content was tested with GC. Bioethanol was successfully produced from foliage using T. viride and Z. mobilis with the highest ethanol content obtained in SSF with a temperature of 35oC and a time of 72 hours, which is 0.2151%.

Abstract

Indonesia is known as a rich country in various agricultural and plantation products, including vegetables such as mustard, broccoli, cabbage, and cauliflower. However, in its cultivation, the products and demand for vegetables are not offset by an increase in the production quality. One of the efforts to improve and enhance the production quality is to identify and characterize chromosomes of plants which will become the basis for plant breeding activities. The purpose of this study was to characterize the number, form and size of the chromosome in cultivars belonging to the Brassicaceae family. The study was carried out using the modified squash method. Chromosomes were prepared by fixation, maceration, and staining, then the mitotic phases were observed using a microscope and optilab, and analyzed using Image Raster 3. The results showed that mitotic time range and chromosome character of six cultivars of the Brassicaceae family were different. Broccoli ('Chief No. 2 1955' and 'Green Super') and cauliflower ('ILONA' and 'TM 126') had a mitotic time range from 04.00 to 09.00 a.m. with 2n chromosome number = 18. Green mustard (‘Juwita’ and ‘TM Jade’) and white mustard ('Sakata' and 'Shuka-shuka') had a mitotic time range from 03.00 to 08.00 a.m. with 2n chromosome number = 20. White cabbage (‘CR ACE' and 'Sehati F1') had a mitotic time range from 04.00 to 09.00 a.m and red cabbage (‘Scarlet’ and ‘Red Globe’) had a mitotic time range from 09.00 to 10.00 a.m. with 2n chromosome number = 18.
