Abstract

Pongo pygmaeus pygmaeus constitutes one of Borneo orangutan subspecies. Orangutans are arboreal animals that utilitize twigs and branches to build a nest. Scientific informations related to subspecies P. p. pygmaeus are considered remarkably rare. The aim of this study was to determine the characteristics of P. p. pygmaeus nesting tree and nest. This study was conducted from April to July 2013, at Peninjau Hill, Kapuas Hulu. Data collection method used in this study was line transect method. The parameters observed were the height of nesting tree, nest height, nest position, nest class and the type of nesting tree. The nesting tree height of  P. p. pygmaeus in Peninjau Hill ranged from 5 m to 39 m with the nest hight ranged from     3 m – 37 m. Generally, the position of nest is at position 2 with nest class mostly in class 4. The nest height significantly corresponds to tree height. Nesting trees consist of 42 trees genera dominated by Santiria. Trees of Dipterocarpaceae family dominate as the nesting tree of orangutan in Peninjau Hill. As much as 46,53% of nesting tree of P. p. pygmaeus also serves as feeding tree.

Abstract

Lemna minor and Hydrilla verticillata are types of water plants that have the potential to have the ability to process and improve the quality of polluted water. The purpose of this study is to determine the ability of Lemna minor and Hydrilla verticillata in improving the quality of laundry wastewater. The study used a completely randomized design (CRD) method with six treatments and three replications. The study was carried out on test media in the form of 5 liters of laundry wastewater with L. minor (L) 100 g, H. verticillata (H) 100 g, and combination treatment of both plants (L1H1, L1H2, L2H1) in weight L1H1 (50 g : 50 g), L1H2 (33 g : 67 g) and L2H1 (67 g : 33 g) for 14 days after acclimation for one week. The combination of L. minor and H. verticillata with a ratio of 1: 2 was able to reduce the highest Total Suspended Solid (TSS) and Total Dissolved Solid (TDS) of laundry wastewater with a decrease of 52.87% and 4.02% and increase dissolved oxygen (DO) of 7.13 mg/L. The highest decrease in chlorine occurred in L. minor and H. verticillata treatments with a ratio of 1:1 of 0.110 mg/L. All treatments of L. minor and H. verticillata both singly and in combination have not been able to reduce the phosphate content in laundry wastewater on day 14 of treatment.

Abstract

The chlorophyll and lipid content in N. oculata can be influenced by the concentration of the culture medium. One of the substances, which has the potential to be an alternative culture medium, is rubber liquid waste. The purpose of this research was to understand the rubber liquid waste influence and its level of concentration as the alternative culture medium for N. oculata in terms of the chlorophyll and lipid content. The research was an experimental study with  completely random design with six treatments are the control (sea water), the concentration 10%,20%,30%,40% and 50% of rubber waste liquid. The chlorophyll content was measured by using spectrophotometer method, while the lipid content was measured by using Bligh and Dyer method. The ANOVA results of chlorophyll a and lipid content were showed a significant effect on the content of N. oculata chlophyll (F5,12 = 9,194; p < 0,05) and lipid (F5,12 = 23,818; p < 0,05). The result of the experiment demonstrated that the highest amount of chlorophyll and lipid was produced by the 10% concentration, 37.71 µg/ml and 3.77 g/200 ml respectively. Furthermore, the 50% concentration produced the lowest amount of chlorophyll and lipid, 2.37 µg/ml and 0.82 g/200 ml respectively.

Abstract

Caladium is a family Araceae which has various colors and patterns of leaves. The mechanism of variation of color and pattern on the leaves is caused by the chlorophyll pigment, carotenoid and anthocyanin. Each variation in color and pattern of the leaf has a different anatomical structure. This research aims to find out the differences in the content of the chlorophyll pigment, carotenoid and anthocyanin as well as examine the anatomical structure of the mesophyll in 6 Caladium plants. This research was conducted from January to May 2016. Measurement of chlorophyll, carotenoid and anthocyanin was conducted using a spectrophotometric method while mesophyll tissue anatomy using the method of wet incision preparation. The results showed that the highest chlorophyll content was found in the leaves of C. schomburgkii by 28.508 mg/l, while the highest carotenoid content was found in C. bicolor 1 by 35.780 μmol/g. The highest anthocyanin content was found in C. bicolor cultivar Blaze by 0.057 mg/g. The cross section area of the red, green and white showed a different mesophyll structure. The green area mesophyll tissue differentiates into palisade and spongy tissue containing chlorophyll, while the red and white mostly showed thet mesophyll tissue that did not differentiate into palisade and spongy tissue. The mesophyll cells in the red area contain anthocyanin, and the white area was not pigmented and there was space between the cells among the palisade tissues and between the upper epidermis and mesophyll tissue.
