Published: June 2020

Land is an important element of the structure underneath a construction, so that the soil must have a good carrying capacity. But the reality on the ground is that many soils have low carrying capacity, so it is necessary to stabilize the soil with gypsum and cement. This study aims to determine the effective percentage of gypsum and cement addition and the effect of the addition of Gypsum and Cement to physical changes in clay soil in terms of the CBR (California Bearing Ratio) value of the curing time. This research was conducted in the laboratory, by testing the physical properties of the soil and the carrying capacity of the soil (CBR) with variations in the addition of gypsum and cement by 1%, 3%, and 5% with a long curing time of 1, 7, and 14 days . Sample testing is carried out with two treatments, namely soil samples are first cured and then compacted and the sample is solidified first and then cured. From the research results obtained the largest CBR (California Bearing Ratio) value occurs in the variation of the addition of Gypsum and Cement 5% with the length of time for soil specimens to be compacted first before curing is equal to 41.54%, this is due to the mixture of soil with gypsum and cement has been manjai solid before the collection can occur, the cavities between soil particles also become solid, so that the strength also increases. From the California Bearing Ratio results, it can be seen that the addition of gypsum and cement to clay soil shows an increase in the value of California Bearing Ratio on clay.

Published: June 2020

Until now, the drinking water companies in Indonesia still use chlorine for disinfection processes. In addition, the chlorine also uses for removal Fe, Mn and ammonia. If the raw water contains high concentration of ammonia, chlorine will react with ammonia form chloramines which have lower strength of disinfection power. The higher concentration of ammonia in raw water caused the higher consumption of chlorine. The reaction of chlorine with certain organic compounds as humic substances will to produce chloro-organo compounds like chlorophenols which become serious problems to day because trihalomethane and also chlorophenols compounds are carcinogenic substances.To overcome the problems one of alternative is using the combination of biofiltration and ultrafiltration to process the drinking water. Biofltrations process is treatment of raw water biologically using fixed bed biofilter reactor witch filled with honeycomb plastic supporting media for removal Fe, Mn, ammonia detergent, and also organic substances. Ultrafiltration (UF) is filtration process using hollow fiber membranes that have effective pore sizes of 0.1 – 0.01 µm. The ultrafiltration units are capable of separating some large molecular weight dissolved organics, colloids, macromolecules and suspended solids from raw water. The ultrafiltration process is designed to remove colloidalized particles in the range from 0.1-0.01µm.By combining the biofiltration and ultrafiltration processes, hence will be got technological alternative of drinking water process which capable to degrade an organic matter, ammonia, detergent and can remove the colloidal or suspended matter effectively without chemicals instead of conventional process. Kata Kunci : Pengolahan Air Minum, Biofiltrasi, Membran, Ultrafiltrasi, Pilot Plant

As a consequence of an intimate relationship with their host plants, most of these insects have a very narrow host range. In this study we report the occurrence of galls on Microgramma mortoniana. Morphological characteristics and field observations are presented. The study was carried out in a seasonal semi-deciduous forest fragment, located in the São João do Oeste municipality, Santa Catarina, southern Brazil. The galls present a fusiform shape and similar indument to the rhizome, in a higher density. In the region of occurrence of the galls, a widening of the rhizome was observed, reaching an average of 9 mm (±1mm), whereas in a rhizome with normal growth the width is 4 (±1 mm). The gall is unicameral, with the following dimensions: 7 mm (±1 mm) x 2 (±1 mm). The larvae observed into the chamber are about 0,7 mm long, being representative of the family Tortricidae (Lepidoptera). In all cases, the rhizomes with galls do not presented continuous development and, consequently, the rhizome has its limit of growth defined by the occurrence of the gall. The results indicate that a greater sampling effort of fern galls in the Neotropics is needed, contributing to the knowledge about the distribution of the galls on ferns lineages.
