Abstract

Paper is needed in large quantities so the need for wood as a raw material for paper is getting higher. Composite paper uses non-wood raw materials can be an alternative to make paper. Bagasse can be used as a substitute for wood fiber and reduce waste in the environment to make composite paper. Likewise, newsprint can be used as a mixture of composite paper. This study aims to compare the quality of composite paper from bagasse and newsprint mixtures using different concentrations of NaOH. The method was an experimental completely randomized design (CRD) consisting three treatments of NaOH (4, 6, and 8%) and 10 replications. The parameters measured were paper thickness, grammage, mass density, and tensile resistance, and were using SPSS ANOVA and continued with LSD test. Paper thickness is affected by the amount of cellulose that was degraded as well as paper grammage, paper thickness and grammage have higher values at the lowest concentration of NaOH (4%). Meanwhile, the tensile strength showed long cellulose had not been degraded much and resulted in higher tensile strength. This also resulted in mass density showing the highest density at the highest concentration of NaOH (8%). In conclusion, concentration of 4% NaOH resulted in paper thickness, grammage, and higher tensile strength compared to 6% and 8% NaOH concentrations. However, the highest mass density was influenced by 8% NaOH concentration compared to 6% and 4% NaOH concentrations.

Abstract

Located around the Mangrove Production and Protection Forest in Tanjung Harapan Village, Kubu Raya Regency, the Bongkok River quality needs to be studied to determine the quality of the river. This study aims to determine the physicochemical quality of water and the community structure of phytoplankton in the Bongkok River during the dry and rainy seasons. The survey method was used at three stations and 9 observation points in both seasons. Phytoplankton types are identified up to the species level. The physicochemical factors observed included temperature, transparency, water flow, pH, salinity, dissolved oxygen, dissolved carbon dioxide, and levels of nitrate and phosphate. The community structure is seen from the abundance, diversity, uniformity, and dominance index values. From a physicochemical perspective, the Bongkok River is a brackish water type with relatively low levels of phosphate and nitrate nutrients and high dissolved CO2, but dissolved oxygen is still good enough to support aquatic life. There are 41 phytoplankton species from 6 classes, including Bacillariophyceae, Chlorophyceae, Cyanophyceae, Dinophyceae, Euglenaphyceae, and Xanthophyceae. The phytoplankton abundance in the dry season is higher than in the rainy season but is still at a low to moderate level. The phytoplankton diversity in the Bongkok River is in the medium category (2.46 – 2.67) but has a high evenness (0.72-0.89) and low dominance (0.11-0.18). Overall, the water conditions in the Bongkok River are sufficient to support the life of aquatic biota. However, the abundance of phytoplankton is still at a low to moderate level, especially during the rainy season.

Abstract

The position of the leaves on each plant can affect the thickness of the leaf tissue. This study aims to determine the thickness of the leaf tissue at the base and shoot positions. The study used a nested design model (random nesting pattern design). This design uses two factors, the first factor is the leaves of six types of monocot ornamental plants, namely adam hawa (Rhoeo discolor), daffodils (Hymenocallis littoralis), hanjuang (Cordyline fructicosa), lilies of paris (Chlorophytum laxum), song india (Dracaena reflexa) and sri fortune (Aglaonema commutatum), while the second factor was leaf position (base and shoot) with three replications. The method of making leaf preserved preparations is paraffin which refers to Johansen. Parameters measured were total leaf thickness, upper epidermis, lower epidermis, mesophyll (palisade and sponge). Data were analyzed with ANOVA followed by LSD if the factor results were significant. The correlation was made between the total leaf thickness and the tissue which was significant on the leaf position factor. The results showed that the type of plant affected the total leaf thickness, upper and lower epidermis, mesophyll (palisade and sponge). However, leaf position has no effect on the thickness of the upper epidermis and sponge for differentiated mesophyll. The thickness of the leaf depends on the thickness of the lower epidermis, followed by the thickness of the mesophyll or palisade for differentiated mesophyll.

Abstract

The Segedong River flows between the Tanjung Prapat Muda Mangrove Protected Forest in Kubu Raya Regency. Mangrove forests contribute nutrients to water. However, nutrients and fluctuative environmental conditions influence the existence of phytoplankton. People’s settlements and fish farming activities downstream of ​​the Segedong River influence environmental conditions. Research on phytoplankton is needed to determine the quality of the Segedong River. The aim of this research is to determine the abundance and diversity of phytoplankton in the downstream Segedong River. Sampling was carried out in the dry and rainy seasons using a survey method at 3 stations. Water physicochemical factors are measured in situ and ex situ. The identified phytoplankton species are then calculated for their abundance, diversity index, evenness, and dominance. 59 phytoplankton species are categorized into 6 classes, including Bacillariophyceae (35 species), Dinophyceae (15 species), Chlorophyceae (4 species), Cyanophyceae (3 species), Chrysophyceae (1 species) and Xanthophyceae (1 species). The phytoplankton abundance obtained in both seasons at all stations ranged from 1,314-10,185 Ind.L-1 or categorized into oligotrophic to mesotrophic. The diversity index ranges from 1.99-2.88 in the medium category. The evenness index ranges from 0.53-0.80, which is in the medium to high category, while the dominance index is low <0.4.
