Abstract

Red spinach (Amaranthus tricolor L.) is one of vegetables which contains anthocyanin. This crop has not planted widely in West Kalimantan since this area has pits land. One of planting techniques to grow this crop on pits land is by adding fertilizer. The basic compost is goat manure. To fasten the composting process, Trichoderma harzianum was added as decomposer. The study was aiming at knowing the effect of goat manure compost with T. harzianum decomposer on the red spinach growth. The study used complete randomized design with 6 treatments. ANOVA result showed that adding compost fertilizer had significant effect on 6 treatment of red spinach (A. tricolor L.), such as plant height (F5,24 = 22,734, p = 0,0001), number of leaf (F5,24 = 17,266, p = 0,0001), wet weight stem (F5,24 = 11,717, p = 0,0001), dry weight stem (F5,24 = 11,770, p = 0,0001), wet weight root (F5,24 = 5,965, p = 0,0001), and dry weight root (F5,24 = 5,196, p = 0,002).

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.

Abstract

Barbodes lateristriga is one of the Cyprinidae Family which has a unique colour scales with different colour intensity in some parts of the body. The aim of this study is to know the brightness level of scale of B. lateristriga which found in Mentuka River. This study was conducted three months from November 2016 to January 2017 in Mentuka River at Pantok, Nanga Taman District, Sekadau Regency. Sample taken by using fishing net, landing net, and posat. Fish sample obtained measured the brightness level of scale at the base of caput, dorsal, and the base of caudal by using modified and scaled Trumatch Colour. The result showed that B. lateristriga had higher brightness level of scales at the base of caput and dorsal is 10 meanwhile brightness level of scale at the base of caudal is 1. Mentuka River is still in good condition to support the life of fish and natural food that exist with the temperature 26-28ºC, depth and brightness level between 32-89 cm and also has high DO level >6 mg/L.
