Abstract
The objective of this study was to determine the effects of different forms of dietary flavonoid on the production performance and intestinal morphology of broiler. A database was built from published literature regarding the various forms of dietary flavonoid. The database contained a total of 103 data points from 39 studies that met the criteria. The different forms of dietary flavonoid were considered as fixed effects, and various studies were treated as random effects, and p-values were used as the model statistics. Results revealed that both dried powders and crude extract of flavonoid increased (p<0.05) average daily gain and villus height of ileum but did not give any significant effects on other parameters. Flavonoids can maintain the health of villus, so it provides the increment of absorption of feed and affects average daily gain. The conclusion of this paper is that the different forms of flavonoids have a positive impact on the production performance and gut morphology of broiler. The best form of flavonoid is through the extraction method base on the enhancement of average daily gain and gut morphology conditions.

Abstract
Sugarcane bagasse surfactant possesses a great potential as local surfactant development material. However, the existing researches regarding sugarcane bagasse as surfactant are still limited on the process of creating surfactant from sulfonation of bagasse lignin, and still unable to cover the Sodium Lignosulfonate Surfactant’s utilization with various concentration and appropriate low salinity on a case of surfactant injection. One of which is by observing surfactant rheology through phase behavior test. The method utilized in this research is a laboratory study by creating a field / reservoir situational conditioning. Surfactant concentration tested in this research were 0.2%, 0.4%, 0.6%, 0.8%, 1%, 1,5% at 6000 ppm; 0.2%, 0.4%, 0.6%, 0.8%, 1%, 1.5% at 7000 ppm; 0.2%, 0.4%, 0.6%, 0.8%, 1%, 1.5% at 8000 ppm by conducting test results and emulsion stability observations and phase behavior. After the test is done, the next step of the test will be the IFT test. The purpose of this research is to know the salinity and concentration of how surfactans can work optimally.

Published: March 2021

AbstractOne of the most popular active materials that are being used in lithium-ion batteries is lithium titanate/Li4Ti5O12 (LTO), as it exhibits zero strain properties as well as high resistance to volume change. Its disadvantages are low capacity and low electrical conductivity. In this experiment, the addition of zinc oxide nanoparticles into LTO as composite is aimed at increasing the capacity of LTO. LTO was synthesized from LiOH and anatase TiO2 using the solid-state method. The composite powders were prepared with 5, 8, and 11 wt.% composition of ZnO-NP. XRD and SEM were used to investigate the composition and microstructure of LTO/ZnO-NP composites. The electrochemical properties of the LTO/ZnO-NP electrode studied by electrochemical impedance spectroscopy, cyclic voltammetry, and charge-discharge. ZnO nanoparticles were uniformly distributed in LTO. The XRD showed a rutile TiO2 and dilithium titanate as a minor phase, while SEM showed particle distribution of LTO/ZnO-NP. LTO/ZnO-NP-11 exhibits excellent cycling performance and high capacity when used as anode with a specific capacity of 166.96 mAh/g at 0.1C, which is better than LTO pure.

Abstract
ND Field is a mature field, whose production has decreased. This field has considerable hydrocarbon potential. With such a large potential, it is possible that in reservoir x which is in the Telisa Formation there is still the potential for hydrocarbons in the un-drainage area outside the area of the producing wells. The reservoir x compartmentalization analysis is carried out using the fault seal analysis method, mapping the reservoir x property combined with the analysis of pressure data between compartments. Reservoir x, production and pressure data are used to analyse the amount of connected gas in place (CGIP) using the P/Z method. Reservoir x connectivity is divided into 4 compartments. CGIP volume analysis using the P/Z method shows CGIP compartment 1 of 1400 MMSCF and for compartment 2 of 350 MMSCF, whereas with volumetric it is found that compartment 3 in place is 261.4 MMSCF and compartment 4 is 413.9 MMSCF.

Abstract
This research aimed to evaluate the use of biochar and liquid smoke as feed additives on gas production and organic matter digestibility of a complete feed in the in vitro rumen fermentation system. Biochar and liquid smoke came from the pyrolysis process of cacao pod husks. Treatments consisted of: control (substrate), biochar BC1 (0.1 mg / ml), BC2 (0.2 mg / ml), BC3 (0.3 mg / ml), BC4 (0.4 mg / ml), liquid smoke LS1 (0.25 ul / ml), LS2 (0.5 ul / ml), LS3 (0.75 ul / ml) and LS4 (1.0 ul / ml). The samples were incubated in vitro with buffered-rumen fluid in four replicates, represented by two incubation units per replicate, and conducted for 48 h at 39oC. Parameters measured in the in vitro evaluation were total gas production and digestibility of organic matter. Data were tested using analysis of variance (ANOVA) and if there was a significant difference at P<0.05 then continued with Duncan’s multiple range test. The results showed that supplementation of biochar and liquid smoke did not affect gas production. However, the addition of biochar and liquid smoke decreased the digestibility of dry matter and organic matter as compared to a control substrate (P <0.05). Furthermore, the addition of biochar and smoke caused a decrease in total protozoa (p<0.05). It was concluded that biochar supplementation and liquid smoke as feed additive reduce protozoa without affecting total gas production and gas production rate.

Authors: Basori I , Krishartadi G D , Sirojuddin S , Sari Y , Syamsuir S 
Published: March 2021

Abstract
This research was conducted to determine the effect of cold rolling and annealing process on the microstructure and mechanical properties of the Cu-30Zn-1Al-1Mn brass alloy produced by gravity casting. Samples were cold rolled with deformation levels of 20%, 40% and 70% and followed by annealing process with temperature variations of 300°C, 400°C, 500°C, and 600°C for 30 minutes. Sample characterization includes chemical composition analysis, microstructure observation and hardness testing. The results illustrate that the Cu-30Zn-1Al-1Mn brass alloy shows the appearance of α and β phases. The cold rolling process with a deformation levels of 20% and 40% promote the formation of a slip and twinning mechanism. On the other hand, samples with a 70% deformation level are dominated by shear bands. The annealing process induces the phenomena of recovery, recrystallization and process of grain growth. The higher the deformation level, the faster the recrystallization process. Furthermore, the smaller the grain size, the higher the sample hardness.

Abstract
Strawberries are popular fruits with high economic value and nutritional content, which are easily damaged. Therefore, the edible coating is one of the steps used to extend the shelf-life of strawberry and maintain its quality. This process uses aloe gel, which contains glucomannan, capable of cross-linking with other ingredients, to bridge the mass transfer of destructive components. The purpose of this study is to examine the influence of additives against the stability of ecogel as an edible coating method for Strawberry fruit in order to maintain its freshness during storage. The method used a factorial complete randomized design to determine the treatment of additives such as acid, potassium sorbate, and calcium chloride into Aloe gel. Secondly, it determines the storage time of Strawberry fruit for 0, 3, 6, 9, 12, and 15 days. The result showed that the Ecogel treatment with the addition of ascorbic acid additives retains the freshness of strawberry fruit till the 9th in cold temperatures of 7 ± 1°C. It also reduces the weight, vitamin C, pH, and total soluble solid of the fruit, while retaining the moisture content.
