Published: March 2020

Abstract
This study focuses on the water quality in a catchment area that is affected by the imperviousness cover. The purpose of this study is to prove the correlation analysis between impervious cover as the independent variable and the water quality index as the dependent variable by analysing the correlation and regression relationship. The study area is located in the catchment area at the campus of Universitas Indonesia, Depok, West Java. The data of the imperviousness is collected from the digital globe imagery and digitized based on identified rooftops. The water quality data is determined based on previous reports and collected manually in the pond by the author. The water collected from the pond will be put for laboratory test to be able to get the quality of the sample according to the determined parameters and then knowing the quality of the pond using the National Sanitation’s Foundation Water Quality Index (NSF-WQI) method. The targeted water quality index is determined based on water usage suitability referring to the Indonesian government regulation number 82/2001. As time goes by, the impervious cover grows and gives an effect to the water quality of the UI cascade-pond. As a tool to set a plan for future development on the catchment area of the pond system in Universitas Indonesia, it is possible to use the linear relationship between catchment area imperviousness and water quality index. After doing a linear regression analysis between imperviousness and water quality, a relationship was found that the change of impervious cover has an effect towards the water quality and is getting worse over time.

Abstract
Public perception of the fulfillment of clean water needs will depend on a number of factors, including social, economic, cultural and community habits. This research was conducted in Nekmese Village in Kupang Regency, East Nusa Tenggara Province. This village is one of the villages that has not received good clean water services, even though this village has sufficient availability of clean water throughout the season. This study aims to examine the perception of rural communities in the provision of sustainable clean water. Data collection is done by observation and survey by interview and questionnaire. The results showed that 41% of respondents felt they were insufficient in providing clean water, while the other 59% felt they were insufficient. This fact is supported by the data on the use of clean water on average by 40 Lpcd. For the sustainability of clean water supply, the results of the study show positive perceptions from the community, but contrary to wasteful measures in water use, maintenance of water sources and participation in water supply in his village. This could be due to the low level of public education, and lack of hearing about information about clean water. The research recommends increasing the awareness and participation of the community in the provision of sustainable clean water.

Authors: Hatmoko J T , Handoko L 
Published: March 2020

Abstract
Most of the soil in the universe contain organic matter that results on the negative effects on the shear behavior of soil. The objective of this research is to study the effect of organic content and proportion of cement of artificially cemented soil. A compaction and direct shear test without curing period were undertaken on the soil with 6, 11, 16, and 21% organic content. Direct shear test results show that the soil cohesion decrease and internal friction angle slightly increase as increasing of organic content. The direct shear test of artificially cemented soil with 21, 28, 42, and 56 curing time was then performed to investigate the effect of cement quantity on the shear behavior of cemented soil. The cement content was 25, 50, 75, and 100 kg/m3. The more cement quantity added to the soil, cohesion and friction angle of artificially cemented soil improves. There is also improvement of the shear stress due to the increase of cement proportion. Similarly, shear strength of stabilized soil improves inherent with curing period due to the short and long-term pozzolanic reactions.

Abstract
A separator is an important part of lithium-ion batteries. Nanofiber separator is one promising material to improve the performance of lithium-ion batteries. SiO2/cPVDF composite nanofiber was successfully synthesis by the electrospinning process. SiO2 nanoparticle, cPVDF, and N-N DMAc were used to synthesis composite nanofiber. SiO2 content influences nanostructure, morphology, diameter and thermal property of nanofiber. Nanofiber separator prepared with the optimum condition of flow rate 0,004 mL/min, voltage 22 kV, and the distance to collector 13 cm. Structure of nanofiber separator was analyzed with ATR-FTIR. FTIR vibration band peak at 1057.8 cm−1 839.4 cm−1 and 761.3 cm−1 were related to Si-OH functional group, a distinctive β phase crystal and α phase crystal, respectively. The average diameter of cPVDF nanofiber, SiO2/cPVDF (0.5%) nanofiber, SiO2/cPVDF (0.75%), and SiO2/cPVDF (1%) were 648.3 nm, 320.6, 347.1, and 388.8 nm, respectively. Effect of addition of silica nanoparticles decreased the average diameter nanofiber. Electrospun SiO2/cPVDF composite nanofiber also showed different thermal behavior under different gases conditions in TGA study, and it is observed that the nanofiber separator could stand until near 400°C before the main chain’s degradation occur. XRD and DSC analysis showed that increasing of SiO2 content decreased crystallinity of nanofiber composite. Water contact angle experimental results of SiO2/cPVDF composite nanofiber revealed an improvement of hydrophobicity with the addition of SiO2 on nanofiber composite.

Published: March 2020

Abstract
A landslide has been one of the many problems in geotechnical engineering, whereas, from one of the cases, a failure happened at the interface layer between the overburden and its underlying soil. As interface shear strength has become one of the growing topics in research, this paper summarizes and discusses the research development of interface shear strength and its possibility to explain the interface shear behavior at a slope. The discussion was limited to cohesive soils and experiment-based behavior of the interface shear. Some research has been selected in order to understand the development of interface shear strength through time and two examples of slope interlayer shear behavior were selected. It was known that there are three common tests of interface shear behavior used: simple shear, direct shear, and ring shear test. The development of interface shear strength started at 1960s between soil and construction materials where the four major components were defined. As the research grows, many other types of soils, interfaces, and the effect of the tests became the topic of the research. In the end, the examples given from modeling the interface shear behavior from a slope gives a new perspective of cases for interface shear strength in slope analysis.
