Published: June 2021

Abstract
With the animal glue binder as raw material, the optimal hydrolysis process of anhydrous sodium carbonate is determined by single factor. The results show that the optimum hydrolysis process is as following. The hydrolysis time is 30 min for a reaction temperature of 60°C, and the mass ratio of water to animal glue is 120:100. The amount of anhydrous sodium carbohydrate is 4wt.% to binder. Under these conditions, the compression strength of binder reaches 2.50MPa, and the surface tension of binder is 33.236 mN/m. The molecular weight of hydrolyzed binder is greatly reduced, and the binder contains hydrophilic molecular groups such as amino and hydroxyl, which improves the hydrophilicity and thermal stability of the animal glue binder.

Abstract
In order to study the grinding mechanism of quartz glass, a three-factor four-level orthogonal test under ultrasonic grinding and non-sonic grinding conditions was designed to investigate the laws of spindle speed, feed rate and depth of cut on the surface roughness of quartz glass. The extreme difference analysis and the analysis of influencing factors were carried out for ultrasonic grinding and non-ultrasonic grinding experiments. The experimental results show that the surface roughness of ultrasonic grinding quartz glass decreases with the increase of spindle speed, increases with the increase of feed speed and increases with the increase of depth of cut. The surface roughness of non-sonic grinding quartz glass increases with increasing spindle speed, increases with increasing feed rate, and decreases with increasing depth of cut. This study provides important implications for the study of the grinding mechanism of quartz glass.

Authors: Yu Cheng Jun 
Published: June 2021

Abstract
The welding quality of reflow welding is closely related to the setting of furnace temperature curve. Based on the law of heat transfer between heat transfer conduction and heat ionization in the process of reflow welding, the mathematical model of PCB plate heat transfer process is established based on the relationship between conveyor belt transfer speed, temperature of each temperature zone and minimum equivalent heat stress in the process of reflow welding, and the optimization model of furnace temperature curve is established with the minimum heating factor and minimum equivalent thermal stress as the optimization target. At the same time, the simulation analysis of stress strain before and after optimization is carried out by finite meta-method, and the results show that the iso-effect force after optimization is reduced by 6.5%, the warp deformation degree of the corner is also reduced to a certain extent, and the maximum iso-effect variable is reduced by 5%. The results provide reference and basis for the improvement of reflow welding process.

Authors: Berian Z Y , Wijaya A T , Iqbal T M 
Published: June 2021

Abstract
Flores has a vast geothermal energy sources, one of the fields, Ulumbu, producing electricity from the geothermal power plant (PLTP). PLTP Ulumbu has two back pressure turbines generating 2.5 MW electricity. Besides geothermal power, Flores has potential solar energy sources that are recorded as much as 5 to 6 kWh/m2/day. The exhaust steam from the backpressure turbine adds the binary cycle as the bottoming unit. It is able to generate electricity continously to supply the baseload. Currently, the peak load of electricity usage in Flores is supplied by the diesel power plant (PLTD). This paper studies the addition of solar collectors and thermal energy storage (TES) as auxiliary components in the binary cycle and simulates the system by using the Aspen Plus. The solar energy is stored in TES during the day and then released to the heat exchanger in the evening. This idea reduces the dependency on diesel power plants in the evening. To increase power as much as 500 kW, the collector area needed to supply the system is 1.1 ha using synthetic oil as HTF. The volume of TES to stored the energy by using nitrate salts as HTF is 1,120 m3. As a result, the efficiencies of the non-hybrid system and hybrid systems are 11.38% and 11.31% subsequently.

Authors: Ginting Elfrida , Zhou Jing 
Published: June 2021

Abstract
Ceria has attracted great attention in recent years in the catalysis community. Metal catalysts supported on ceria exhibit a promising catalytic activity due to the ceria’s unique redox properties and oxygen storage capacity. The purpose of this paper is to look at the fundamental aspect of CeOx(111) thin films on Ru(0001). The investigation presented in this paper utilizes the surface science method to understand the properties of CeOx(111). In one component, through a series of XPS studies, it is shown that the deposition of Ce in the presence of oxygen on Ru(0001) can produce ceria thin films. Fully oxidized CeO2 can be obtained with an oxygen pressure of 2 x 10−7 Torr. With the decrease in the oxygen pressure, partially reduced CeOx films can be prepared. Moreover, STM images are collected from the CeO2 growth in the presence of 2×10−7 Torr of oxygen and partially reduced ceria with oxygen pressures of 8×10−8 Torr. These films can completely cover the Ru(0001) substrate. The measured step height is about 0.3 nm, which is consistent with the 0.313 nm spacing of O-Ce-O tri-layers in the CeO2(111) fluorite bulk structure.

Abstract
The Paris Agreement calls for universal action to tackle climate change. Accordingly, countries have laid out their climate mitigation pledges and strategies on their Nationally Determined Contributions (NDCs). Most of the submitted NDCs include climate actions in the energy sector as a part of a national strategies in achieving their Paris climate targets. This paper assesses the alignment of the Indonesian power sector’s pathway with its Paris Agreement targets. Furthermore, we analyze the role of climate change mitigation in the power sector to Indonesia’s SDGs targets. We also identify how Covid-19 might affect the power sector development and subsequently the sector’s contribution to NDC. We review the literature and energy sector’s publications and apply the SDG interaction framework developed by Nilsson et.al. (2016) for our analysis. Our results indicate how the power sector’s pathway contributes to both NDC and SDGs targets.

Abstract
The mixing of non-halal meat in meatballs cannot be physically distinguished, so an approach based on molecular genetics is needed. However, until now there has been no information on the proper DNA purification method to obtain DNA from meatballs. This study was designed to obtain the most appropriate method of DNA purification from meatballs through modification of the preparation and number of samples used as the basis for halal authentication genetic marker-based. The study was conducted using a completely randomized design, in which the preparation method as the main factor consisted of fresh sample preparation (P1), oven-dry sample preparation (P2), and freeze-drying sample preparation (P3). The second factor is the sample weight consisting of a sample weight of 25 mg (B1), a sample weight of 50 mg (B2), a sample weight of 75 mg (B3), a sample weight of 100 mg (B4). Each treatment combination was cashed twice so that the number of experimental units was 24. The results of this study indicated that there was no significant difference (P> 0.05) between the treatment methods of sample preparation and sample weight to the purified DNA concentration of meatballs. There was also no significant difference (P> 0.05) between the treatment methods of sample preparation and the number of meatball samples on the purity of DNA purified from the meatballs. So it can be concluded that the preparation method and the number of samples did not affect the concentration and purity of purified DNA from meatballs.

Abstract
This research aimed to investigate the reproductive performance of Ongole crossbred (PO) cows offered zinc methionine (ZincMeth) during the late gestation and early lactation. Thirty-two PO pregnant cows, 400 kg live weight (LW) were weighed and measured body condition score (BCS) before the experiment. The experimental design was a 2 x 2 factorial with two nutritional and two ZincMeth treatments, with eight cows in each nutrition x ZincMeth group. All cows were offered elephant grass (EG), 16 cows offered a concentrate diet (CONS) containing 15% crude protein (CP) and 16 cows offered a CONS containing 11% CP at 3% LW on a DM basis, the ratio of EG: CONS was 40:60. Five grams of ZincMeth was added to the CONS prepared for individual cows. The parameters observed were LW gain, BCS, post-partum anestrus period, luteinizing hormone, volatile fatty acid, and blood metabolite concentrations. The results showed that the BCS change was greater in cows fed a high CP diet, they also had high plasma glucose, urea, and total protein concentrations. ZincMeth prevented LW loss in the early lactation and increased plasma urea concentration. Thus, the ZincMeth maintained the LWG during the critical period but did not affect any reproductive parameters.
