Abstract
The purpose of this research work is to study the hardening behavior of the alkali activated slag-metakaolin (AASM) material from a new electrochemical perspective. The measurements of the compressive strength and the electrochemical impedance spectroscopy (EIS) were conducted. The results demonstrated that the strength of AASM paste decreases with the increase of metakaolin content. In addition, a suitable electrochemical equivalent model has been used in order to analyse of the relationship between the microstructure of the AASM paste and the EIS data. And found that the resistance of ion transport process Rct1 show an increasing trend over the testing period and the compressive strength and the Rct1 of AASM has similar growth trend and strong correlation, which means that the EIS may be used to predict the strength development of the AASM paste.

Abstract
In order to explore the influence of alkali concentration, solid-liquid ratio, pretreatment time and component ratio on biogas production from corn stalk anaerobic fermentation in the pretreatment process of combined alkali, four factors and five levels of quadratic orthogonal rotary combination design experiment were used to optimize the technological conditions for biogas production from corn stalk anaerobic fermentation by combined alkali pretreatment, and corresponding mathematical model is established. The results showed that the regression equation was significant and the fitting condition was good. The four factors affected the biogas production of corn stalk in the order of composition ratio, treatment time, alkali concentration and solid-liquid ratio. The optimum combination of process parameters was as follows: alkali concentration was 6%, solid-liquid ratio was 1:5, treatment time was 4.5 days, component ratio was 1:1.25. Under the optimum conditions, the production of biogas from corn stalk anaerobic fermentation was the highest.

Published: August 2019

Abstract
An ultrathin NiO nanosheets array loaded on carbon spheres were prepared by coprecipitation method and calcination approach. The as prepared NiO nanosheets contain high surface specific area due to their cross-sectional NiO three-dimensional structure which leads to more susceptible contacting between nanosheets and electrolyte. As the results, the reversible redox reaction should be accelerated. Moreover, NiO nanosheets array@carbon sphere (NiO@C) nanocompounds were mixed with Nafion solution and loaded onto glassy carbon electrodes (GCEs) to form a high performance non-enzymatic electrochemical glucose sensor. Cyclic voltammetric (CV) and Amperometric studies indicated NiO@C nanocompounds demonstrated excellent electrocatalytic activities for glucose detection.

Authors: Lu Yangjie , Li Juan , Guo Zhen 
Published: August 2019

Abstract
The experiment was carried out by planting corn on the compound soil formed by mixing different proportions of soft sandstone and sand. The distribution and migration of nitrate nitrogen and ammonium nitrogen in the compound soil were studied. The results showed that: 1.Soil nitrate nitrogen was easily leached by water, and the greater the proportion of sand in the compound soil, the faster the soil nitrate nitrogen was leached and the depth of the leaching is deeper; 2. The content of ammonium nitrogen in the compound soil was generally low, and the higher the sediment concentration of the compound soil, the greater the change of ammonium nitrogen. Therefore, appropriate measures should be taken in the compound soil with high sediment concentration to reduce the fertility waste caused by nutrient loss.

Published: August 2019

Abstract
Ultrasonic was widely studied in soil or sediment with several types of contaminants, both heavy metals and organic matter. Ultrasonic may enhance the desorption or leaching of contaminants from the soil and play an important role in the formation of radicals (•OH) that involved in the oxidation of hydrocarbon contaminants in the soil. This research has consisted of a tube reactor made from stainless steel in 21 cm × 21 cm × 18 cm of volume. According to previous research, ultrasonic power not only increases the desorption process or leaching contaminants from the soil but also plays an important role in the formation of radicals (•OH) which are oxidizers involved in the oxidation process. The main reactor has a dimension of 21 cm × 21 cm × 18 cm. The system used was a bath system, where the transducer was attached under the bath (reactor) so that it indirectly produces sonication. Contaminated soil has low permeability and obtained from conventional petroleum mining in Grobogan Regency, Central Java. Initial concentrations of TPH was 334100 mg / kg. Based on the optimum time experiment, it can be seen that the TPH removal was significant at the initial 15 minutes of sonication. At optimum conditions, TPH efficiency removal at 160 watts of power, 48 kHz of frequency, 1: 9 (gr/ml) of soil / liquid ratio was 61.03%.

Abstract
Padang City is located on the West coast of Sumatra Island that borders directly with the Indian Ocean. The coastal region of the city stretches from Pasia Jambak beach, Muara Anai in the Northto Sungai Pisang in the South. The coast of South section is different from the coast of Northsection, because the Southern coastline is heterogeneous because there are many small bay, small islands and narrow beaches directly adjacent to the volcanic hills. This research aims to determine the dynamics condition of a coastal environment based on the characteristic (length, velocity, energy, and height), sediment transport value, accretion/abrasion factor value, and coastal equilibrium in Padang City.The method used in this study is the calculation of wavelength (L0
), wave velocity (C), wave energy (E), run-up height (Hb
), and sediment transport (Q) to determine accretion/abrasion factor and equilibrium (G0
). Furthermore, it is done by Geographic Information System (GIS) approach to spatial information of research location. Research result shows that coastal region(beach)in Padang City tends to experience accretion along the beach of Pasia Sabalah, Panjalinan North, Panjalinan South, Parkit, Purus South, Purus North, Muaro Padang, Air Manis North and Pasia Putih. While the abrasion conditions occur inPasia Jambak, Parupuk Tabing, Bung Hatta University beach, Air Manis South and Sungai Beremas.

Abstract
Indonesia is the largest archipelagic country in the world, there are thousands of small islands that have to be managed. One of the main managements in small island is related with sanitation issue, especially the fecal (black water). This research is aimed to identify the characteristics of fecal disposal system in a small island and analyse the related factors affecting it. The research was conducted in Penyengat Island, Kepulauan Riau. Descriptive and Inferential Statistics were applied by using SPSS. The characteristics of fecal disposal system is determined by latrine and sewage disposal type. Meanwhile, the related factors included are settlement type, education, income, and ethnicity. The result shows that fecal disposal system of Penyengat is dominated with modern latrine (71.4% Gooseneck Latrine) and conventional sewage disposal (53.5% simple pit sewage). Preferency of fecal disposal type is related with settlement type, ethnicity, and highest education level of household members. Besides, the income level is not related with the fecal disposal type at all. The result of this research is expected as a reference of sanitation programs in small island.

Composition of mixing gypsum additives as environmentally friendly material in tropical soil to reduce grounding resistance
Authors: Martin Yul 
Published: August 2019

Abstract
Grounding resistance is directly proportional to the amount of soil type resistance. While soil type resistance is influenced by several things, namely soil structure, temperature, the effect of water content (moisture), and the effect of chemical content in the soil. The purpose of this study was to analyze the decrease in the value of earth resistance by adding additives in the form of gypsum without a mixture of soil and gypsum mixed with soil. The results showed that the value of grounding resistance with the addition of gypsum without soil mixtures had a higher resistance value than grounding resistance without the addition of additives. Grounding resistance with the addition of gypsum mixed with soil on average can reduce the value of grounding resistance by 153.56 ohms with 25% gypsum, 157.2 ohms with 75% gypsum and 169.91 ohms with 50% gypsum.
