Abstract

Black orchid (Coelogyne pandurata Lindl.) Is an endemic germplasm Kalimantan. This orchid is in great demand because of the potential to have high economic value. Consequently, it is often overexploited, yet it has not been widely cultivated. This research aims to find out the effect of augmenting tomato extract and benzyl amino purine (BAP) in the growing of black orchid. This research started from January to March 2017 in Tissue Culture Laboratory Aloe Vera Center (AVC) Pontianak. This research used Completely Randomized Design (CRD) with 2 treatment factors and 3 repetition. The first factor was tomato extract (0%; 7,5%; 10%; 12,5%) and second factor was BAP (0 M; 10-6 M; 10-7 M). The results show that the single factor of tomato extract and BAP and the combination factor also did not have a real effect on the time shoots appear and the number of leaves. The interaction factor of tomato extract and BAP did not have a real effect on the number of shoots, but the single factor of tomato extract and BAP had a real effect on the number of shoots and single factor of BAP had a real effect on the number of leaves. The highest number of shoots was 3,33 in the treatment of tomato extract 7.5% and 1.33 in the treatment of BAP of 10-6 M. The highest number of leaves was 11.33 sheets in the treatment of tomato extract of 12,5% and the lowest number of leaves was in the treatment of tomato extract of 10% and BAP of 10-6 M with an average of 3,00 sheets.

Abstract

The treatment of liquid waste from rubber can be done with a biofilter method, which is by using micro-organisms attached to the filter to help the process of organic material degradation. The changes that occur to the organic substance in the waste will affect the composition of microalgae and protozoa during the treatment process. The purposes of this research is to find out types of microalgae and protozoa, their abundance in the rubber waste water treatment plant, and the quality of waste during the treatment. The research was conducted from September 2014 until January 2015. The research was conducted on the laboratory scale through observation of the microalgae and protozoa growth. The findings indicates that there are 36 genera of microalgae and 7 genera of protozoa. It shows that the highest abundance in the group of microalgae belong to Chlorophyceae class, whereas protozoa group is in the Sarcodina class. The genus which is able to adapt well would survive during the waste treatment processing. The genus which survived during waste  treatment process from the microalgae group was Cyanidium and from the protozoa group was Arcella.

Abstract

Jabon (Anthocephalus sp.) is native species of Indonesia and the cultivation of white jabon in west Kalimantan is still rare. One of the efforts to increase the production of jabon is through vegetative propagation shoot cutting. Propagation through shoot cutting often fails, in which the roots cannot grow. One of the ways of overcoming such failure is by providing exogenous growth regulator, namely, goat urine. This research aimed to find out the effect of the concentration of goat urine (Capra aegagrus) and soaking time on the growth of the shoot cuttings of white jabon. This research used a completely randomized factorial design (CRD) i.e. the factor of concentration (A) consisting of 4 levels of 0%, 6%, 8%, 10%, 12% and the factor of soaking time (B) consisting of four levels, i.e. 0 min, 5 minutes, 10 minutes and 15 minutes. The treatment was repeated three times. The research findings indicated that adding goat urine concentration of 12% and 15 minutes soaking time generated the average root number of 29 pieces, the plant height of 20.33 cm, thewet weight of 16.33 grams and the dry weight of 3.46 grams, and the average number of leaves of 9 pieces, which were obtained from the treatment of a concentration of 10% and a soaking time of 15 minutes.

Abstract

One alternative of fresh milk preservation is by adding sugar that derived from the hydrolysis process of blue taro tuber. The aim of this study was to examine the quality of fresh milk after the addition of oligofructose syrup. The study was carried out from April to June in 2013. Based on the ANOVA test, it was known that the concentration of oligofructose syrup influenced the increase of proximately test, total number of bacteria, and reduction time of milk. The protein content of milk increased to 0.25% after being added by oligofructose syrup with 20% concentration, and then it became 3.95 %. The lactose content increased to 2.05% after being added by oligofructose syrup with 40% concentration, and then it become 6%. The highest increment of milk acidity occurred over milk by adding 40% of oligofructose syrup. Furthermore, 40% milk fat and oligofructose syrup decreased to 2.40%, which it became 2%. Total number of milk bacteria decreased to 23x103 CFU/ml after being added by 40% oligofructose syrup, but then it become 26x103 CFU/ml. In this study, no indication of coliform was found in all milk samples. Best time of reducing bacteria occured over milk added 40% syrup is 634 minutes.

Abstract

White jabon (Anthochepaluscadamba) has high prospects for plantation forest and reforestation plants. Woody plants like white jabon (A. cadamba) are commonly used by ants for nesting. This research aims to find out the diversity of genera and distribution patterns of ants in the plantation area of white jabon (A. cadamba) in Sungai Durian Village, Sungai AmbawangSubdistrict. Data were collected through combined methods of transect and plot line in two sampling locations in the plantation area of white jabon (A. cadamba). The first location is a newly cleared land with jabon plants aged more or less 12 months. The second location is a previously horticultural farmland that was converted into agricultural farmland of jabon aged more or less 8 months. Samples of ants were collected with pitfall traps, bait traps, soil core sample and hand collecting. The results of sampling found 4 genera of ants i.e. Iridomyrmex, Solenopsis, DiacammaandMonomorium. Genus Iridomyrmex was a genus with most individuals (983 individuals) andMonomoriumsp was a genus with the fewest individuals (296 individuals). The index value of species diversity at both locations was low (Location 1 H '= 1.376 and Location 2 H' = 0.6843). The genus which dominates was not found and the condition of both locations was stable. Sorensen similarity index showed that both locations had a high similar genus (IS = 66.67%). All the ants had a clustered distribution patterns.
