Abstract

Sungai Jawi and Sungai Raya Dalam canals were frequently benefited by communities for a variety of daily necessities. These activities led to changes in water conditions and disrupt community structure in it. The purpose of this study was to determine the periphytic micro-algae community structure and the level of water pollution in Sungai Jawi and Sungai Raya Dalam canals. The samples were collected in Sungai Jawi and Sungai Raya Dalam canals. The determination of stations was based on environmental setting. Each canal was divided into 4 stations with 3 points laying substrate. The results showed that the periphytic micro-algae were from 3 divisions and 3 classes, namely Chrysophyta (Bacillariophyceae), Chlorophyta (Chlorophyceae), and Cyanophyta (Cyanophyceae). There were 26 genera of periphytic micro-algae in Sungai Jawi Canal and 25 genera of periphytic micro-algae in Sungai Raya Dalam Canal. Total abundance of periphytic micro-algae in Sungai Jawi Canal was 378,15 - 651,86 ind/cm2 and in Sungai Raya Dalam was 488,50 - 657,13 ind/cm2. The highest abundance was found in the both canal from the Bacillariophyceae class, Navicula genus. Shannon-Winner diversity index on Sungai Jawi and Sungai Raya Dalam canals was classified as middle category (2,0393 - 2,5690). Pollution level that occurred on both canal was still relatively mild.

Abstract

Black orchids (Coelogyne pandurata Lindl.) are epiphytic and endemic in Borneo. Habitat damage and over exploitation by the society can cause black orchids to be threatened with extinction. For this reason, alternative ways to increase black orchids are needed through tissue culture techniques with the addition of ambon banana extract and Benzyl Amino Purine BAP. The aim of this study was to determine the effect of ambon banana extract and BAP on the multiplication of black orchids. This research was conducted for 3 months from January to March 2018 at Pontianak Aloe Vera Center (AVC) Tissue Culture Laboratory. This study uses a Completely Randomized Design (CRD) with two factors. The first factor was ambon banana extract (0%; 2,5%; 5%; 7,5% and 10%) and the second factors BAP (0 M; 10-7M; 10-6M; 5x10-6M) with 3 replications, each of which obtained 60 trial unit. The results showed that the ambon banana extract had a significant effect on the time of budding, number of buds and number of leaves. The concentration of ambon banana extract 2,5% resulted in the fastest budding time appearing on the 11,33th day, the number of buds was 8,33 tillers, and the number of leaves was 17,67 strands.

Abstract

Nepenthes bicalcarata commonly grows in the edge of swampy mangrove forest and heath forest which are poor in nutrients and have a relatively high humidity. The conservation effort on  N. bicalcarata can be done through plant multiplication by stem cuttings. This study aims to determine the effect of  indole butyric acid (IBA) growth regulator addition on the growth of N. bicalcarata stem cuttings and to determine the concentration of  IBA growth regulator  that can give the best growth on  N. Bicalcarata stem cuttings. The study was conducted in November 2013 to February 2014. Based on  ANOVA analysis, the addition of IBA on N. bicalcarata stem cuttings significantly affected the height of the plant and the number of roots. The best IBA concentration given on N. bicalcarata stem cuttings was at 15 ppm, resulting in 19,50 cm of  average plant  heights and  27,25 of average roots number. The addition of IBA did not significantly affect the number of  leaves and initial budding period.

Abstract

Sugarcane juice is a drink that is quite favored by the people in Pontianak city. However, most sellers of sugarcane juice do not pay attention to hygiene in the use of equipment, storage and processing of sugarcane juice. This can be a cause of microbial contamination in sugarcane juice. The research aims to determine the microbial contamination based on the examination of Total Plate Count (TPC) and Most Probable Number (MPN) coliform in sugarcane (Saccharum officinarum) juice in Pontianak city. The samples in this research were sugarcane juice drinks without ice taken each 10% of the total sellers randomly in every district in the city of Pontianak. This is a descriptive study using TPC and MPN coliform methods, and supporting data such as temperature, humidity and hygiene factor. The results of the 30 samples tested showed the average TPC ranging from 2,4 x 104 to 1,7 x 105 CFU/ml and the avarage value of MPN coliform was >1100 CFU /ml. The values exceeding the threshold value of microbial contamination in juice drinks based on SNI 3719: 2014 in which for TPC the maximum is 1 x 104 CFU/ml, and for MPN coliform the maximum is 20 CFU/ml

Abstract

Phytoplankton plays an important role in aquatic ecosystem as a primary producer. This study aims to determine the genera, abundance and horizontal distribution of phytoplankton and to measure the physical and chemical characteristics in the estuary of Kakap River. The study was carried out between December 2013 and May 2014. Phytoplankton samples were taken from five stasions that were determined based on the differences in the environmental conditions by Adaptive Cluster Sampling Method. The samples of phytoplankton were taken when the river water was in a tidal conditions by plankton net. The composition of phytoplankton found in estuary of Kakap River composed of 7 divisions, 7 classes and 42 genera. The highest phytoplankton abundance found at high tides were 42,825 ind/L and 35,769 ind/L respectively. The highest abundance phytoplankton was found from Bacillariophyceae (43,329 ind/L). Horizontal distribution of phytoplankton showed that the further away from the area of river basin, more abundance and more diverse of phytoplankton. Based on the value of Diversity Index (H’) (3.006 - 3.3489), Dominance Index (D) (0.0473 – 0.0613) and Evennes Index (E) (0.7118 – 0.8548), the estuary of Kakap River was in stable condition with high diversity. Characteristics of physial and chemical factors in the river were able to support the life of phytoplankton.
