Pertumbuhan Stek Batang Sirih Merah (Piper crocatum Ruiz.) Setelah Perendaman Dengan Ekstrak Bawang Merah (Allium cepa L.) Dan Air Kelapa (Cocos nucifera L.)
Get PDFThe Red betel (Piper crocatum Ruiz.) is one of the types of plants that can be used as a medicinal plant. The Red betel plant can be propagated through cuttings, but the ability of the Red betel leaves to stem cuttings rooted very low. The purpose of this research is to know the influence of the concentration of soaking onion extract and coconut water towards the growth of the stem cuttings of red betel. This study used a randomized complete design (RAL) factorial with two levels, namely the first factor extract of onion (B) that consists of 4 concentrations, namely control (0%), B1 (2,5%), B2 (4%), and B3 (5.5%). The second factor is cocnut water (K) consisting 0f 4 concentrations of control (0%), K1 (15%), K2 (20%) and K3 (25%), retrieved 16 combination treatments 3 replications to obtain 48 units of the experiment. The results showed that the combination of onion extract 5.5% + 25% coconut water shows most good for the number of leaves, plant height, wet weight of heading, the heading dry weight, root weight of wet and dry weight of roots
Tingkat Kecerahan Sisik Ikan Arwana Merah (Scleropages formosus)
Get PDFRed Arowana fish (Scleropages formosus) was known for their bright color. The color patterns were formed by the first and second ring of the scales. This research aims to examine the brightness level of S. formosus scales based on their age. Nine individuals of S. formosus were divided into 3 groups according to their age (1 year, 2 years and 3 years old). Samples consisted of 5 scales were collected from caput, dorsal, and caudal, respectively. The brightness level of the scales were measured by comparing them towards a modified color scaling paper. There were increase in brightness level of the first ring (17,93%) and the second ring (11,47%) of the scales. The brightness level of the scales were also found to be increased along with the fish age

The study found 27 Anura species included in 6 families namely Megophryidae (Megophrys nasuta), Bufonidae (Ansonia sp. and A. spinulifer), Microhylidae (Microhyla malang, and M. perparva), Ranidae (Meristogenys jerboa, M. whiteheadi and Staurois guttatus), Dicroglossidae (Limnonectes leporinus and L. kuhlii), and Rhacophoridae (Kurixalus appendiculatus, Rhacophorus sp., R. gauni, and R. pardalis)
Respon Pertumbuhan Vegetatif Tanaman Buncis (Phaseolus vulgaris L.) Dengan Pemberian Kompos Limbah Kulit Pisang Nipah
Get PDFBean (Phaseolus vulgaris L.) is a type of legumes from leguminoceae familly which is beneficial to decrease blood pressure and control body metabolism system. Bean can grow well on rich soil which contains much humus. This research aims at identifying the effect of Nipah banana’s skin waste towards the vegetative growth of bean. The research was conducted for thee months since Febuary to April 2017. It was carried out in a lab of biology deapartment, Faculty of Mathematics and Natural Sciences, Tanjungpura Universty. The research employed completely randomized design ( RAL). It consisted of six level of concentration, such as control (P0) 0 (P1) 12.5 (P2) 25 (P3) 37.5 (P4) 50 (P5) 62.5g. They ware carried out with three repetitions so they could gather 18 experimental units. Providing bean with the banana’s skin waste could give a clear effect towards the plant’s heights, gross weight, and dry weight. Using the banana’s skin waste whice has 50g concentration provides the best resulty for the plant’s height (141.30 cm), the number of leaf (37.67 leaves), and dry weight (12.54 g)

Get PDFCellulolytic bacteria were a group of bacteria involved in coffee fermentation in the digestive tract of civet (Paradoxurus hermaphroditus). The aim of this research was to detect the presence of cellulolytic bacteria isolated from civet feces. This research was conducted from December 2015 to February 2016. Samples of civet feces were collected from Bandung Zoo. Bacteria were isolated from civet feces and screened for cellulolytic activity in Carboxy Methyl Cellulose (CMC) media. Positive result for cellulose producing activity was indicated by the formation of clear zone around the colony. Characterization of the isolated bacteria was done based on macroscopic and microscopic observations followed by biochemical test. A total of 9 genera of cellulolytic bacteria were identified from the civet feces samples, such as Xylophilus (BSKL 1), Caryophanon (BSKL 2), Aeromicrobium (BSKL 3), Exiguobacterium (BSKL 4, BSKL 11), Brochotrix (BSKL 5), Alcaligenes (BSKL 6), Alteromonas (BSKL 7), Halomonas (BSKL 8), Chromobacterium (BSKL 9), Corynebacterium (BSKL 10, BSKL 13), Cellulomonas (BSKL 14) and BSKL isolates 12

Get PDFCavendish banana (Musa acuminata L.) is classified into Musaceae Family which is originally from Southeast Asian. The superiority of this banana is its size which is bigger and it has 10 hand of bananas. The addition of growth regulator (zpt) in the tissue culture medium is a vital component in the process of the growth and the development of the plants in vitro. This research aims at identifying the influence of NAA and coconut water toward the multiplication of cavendish banana through in vitro. The research was conducted for three months since January to March of 2017 in the local Laboratory of Regional Technical Implementation Unit (UPTD) of Aloe Vera Agribisness Centre (AVC) at Agriculture, Fishery, and Forestry Agency of the Pontianak, North Pontianak sub-district. The research empoyed a completely randomised design with four level factors of NAA (N) with concentration of 0 M (N1), 10-7 M (N2), 5x10-6 M (N3), 10-6 M (N4) and coconut water (A) with concentration of % (A1), 10% (A2), 15% (A3) and 20% (A4).
