Abstract

Lactobacillus sp are gram-positive bacteria that cannot survive in acidic conditions, such as stomach acid conditions (pH 1.5- pH 2.5) so that a carrier is needed so that Lactobacillus sp can survive when colonizing the intestine. One way to protect Lactobacillus sp in acidic conditions is by encapsulation. The core material used for Lactobacillus encapsulation uses a mixture of Na-alginate and chitosan. The mixture formed then becomes microcapsules using an electrospinning device. One of the components of the electrospinning device is a syringe that provides pressure to form droplets that fall into a solution of CaCl2 and chitosan with a concentration of 1.2%; 1.6% and 2%. Lactobacillus sp. The encapsulated viability was tested for viability in simulated gastric acid (0.2% NaCl pH 1.2 and pH 3) for 1 minute, 60 minutes, and 120 minutes using the Total Plate Count (TPC) method. After the viability test was carried out, it was found that Lactobacillus sp. encapsulation results with a 2% chitosan matrix with the number of colonies in the simulated gastric acid pH 3 for 1 minute is 4x109 cfu / g, for 60 minutes 3x109 cfu / g and for 120 minutes is 1x9 cfu /g.

Abstract

The advantages of coconut coir powder (cocopeat) are resistant to microorganisms, weathering and resistant to mechanical spelling, namely friction and blows. Based on these advantages, cocopeat can be used as a blend of fine aggregates in the manufacture of concrete. The sieve test was conducted on the cocopeat to determine the initial feasibility analysis of cocopeat as a blend of fine aggregates in the concrete manufacturing. The results of the cocopeat sieve test are that cocopeat is included in Region II which is classified as a fine module of slightly coarse grains with a fine module of fine aggregate grains of 2.37. This shows that cocopeat has a fairly good value in normal concrete mixtures but is not suitable for high resistance concrete mixtures that exceed 25 MPa. This was followed by a subsidence test that gave subsidence values for mixtures of concrete with a cocopeat composition of 25%, 50% and 75%, is 7.5 cm; 5.3 cm; and 2.2 cm. While a good subsidence ratio is used in the range of 6-18 cm. In addition, the concrete with a 25% blend of cocopeat has a stronger physical form and there are no fungus growing on the surface of the concrete. Meanwhile, concrete with a mixture of 50% and 75% cocopeat looks more fragile and forms molds on the surface of the concrete. Thus the concrete with a mixture of 25% cocopeat has better results.

Abstract

All living things need water, because water is the most important essential material for life. One of the substances in water is iron (Fe). According to Permenkes RI number 492 / MENKES / PER / VI / 2010 levels of iron (Fe) allowed in drinking water is 0.3 mg/L. This study aimed to determine the amount of Fe metal content in PDAM water in Pidie Jaya Regency (Mon Krueng Meureudu PDAM, Panteraja PDAM, and Ulim PDAM) using the Atomic Absorption Spectrophotometry (SSA) method with wet destruction. The results of the analysis of iron content in PDAM water in Pidie Jaya Regency are PDAM Ulim 0.0628 µg/L, Panteraja PDAM 0.1068 µg/L, and Meureudu PDAM 0.0055 µg/L. In other words, PDAM water in Pidie Jaya Regency is still at the specified level. It is expected that PDAM Pidie Jaya will continue to maintain the quality of iron (Fe) levels so as not to exceed the maximum levels that have been set.

Abstract

This paper examined throughput optimization issue in wireless mesh network (WMN), the weakest point of this network in regard to this matter.   A number of previous studies on this issue have been conducted, but most focus has been on general wireless network, only few studies so far have attempted on this network. This research aimed to optimize the CARA rate adaptation control algorithm in WMN network. The optimization was performed by adjusting the successtreshold and timeout parameters in the CARA algorithm to obtain an optimal throughput. The optimal result is showed that the optimal points of the success threshold and timeout are at range of 30-35. It is obviously seen in grid 4×5 and 5x5 where the throughput value of the optimization result continues to increase. Moreover, by adding the data transmission time for 100 seconds on grid 5×5 resulting the throughput value of 0.52206412 Mbps and after the optimization the throughput value increases up to 117% to 1.1350768 Mbps, when the success threshold and timeout value are 30. For an additional  150 seconds, the throughput value is 0.5074419333 Mbps and after the optimization the throughput increases up to 120% to 1.1211402 Mbps, when the success threshold and timeout value are 35.

Abstract

Groundwater is the  primary source of clean water for  Cimahi City residents. Groundwater quality has decreased due to contamination of domestic wastewater as it is managed  through  local systems that do not meet standards. This study aims to analyse  the feasibility of shallow groundwater as a source of clean water in the town of Cimahi . The data used are  secondary to the Environment Service for  2018. Sampling was conducted  in 12 urban villages such as Citeureup, Pasir Kaliki, Cibeureum, Cibabat, Cipageran, Cimahi, Leuwigajah, Setiamanah, Cibeber, Baros, Karang Mekar, and Melong. There are 1 to 2 samples in  each village  . Based on field measurements, several parameters have not  exceeded the required quality standards, namely turbidity, Manganese, Nitrate, MBAS Detergent, and Total Coliform. Groundwater quality from 20 sampling points only 4 points (20%) which  meet the quality standards and are suitable as a water source, the remaining 16 sampling points (80%) are declared unfit for sampling because  one to three parameters that do not meet the quality standards. Management can occur by improving the local system or by beginning  to plan a centralized wastewater treatment system that uses piping to reduce  groundwater contamination.

Abstract

Dengue Hemorrhagic Fever (DHF) is an endemic disease caused by a virus and transmitted by vectors, especially Aedes aegypti and Ae. Albopictus. The number of cases tends to increase and is widespread in almost all regions. This study aims to determine the different types of water sources on the attractiveness of Aedes aegypti for laying eggs. The research method uses the One Way Anova statistical test analysis with α 0.05. The results showed the One Way Anova test obtained p value = 0.048 (p 0.05) meaning that there are differences in the type of water source to the attractiveness of Aedes aegypti mosquitoes to lay eggs, especially in well water with river water with a value of p = 0.016 (p 0, 05). The difference in the number of mosquito eggs found in containers containing rain water, river water and well water indicates that the Aedes aegypti mosquito has different appeal in laying its eggs. The community should always maintain sanitation, especially containers that hold water so that it does not have the potential to become Aedes aegypti mosquito nest sites and can reduce the density of Aedes aegypti mosquitoes.
