Abstract
Singosari National Artificial Insemination Center (SNAIC), East Java is one of the most important Government Institution which produces frozen semen from elite bulls and distributes it to overall Indonesia regions of the most part and to overseas of the other small part. The local elite bulls at SNAIC were originated and selected from the population based on the phenotypic characteristics and pedigrees. While the exotic breed was originated from the certified elite bulls from company in overseas. This paper was aimed to review the consistency of semen production of elite bulls over the years from 2012 to 2018. The semen production was controlled by the age of bulls. The semen volume was quite low from the age of 2 – 4 years old, increased from 5 – 8 years old, and reached maximum volume by 9 years old and forward. The individual motility of sperm was low in first phase of semen collection by age of 2 years and then reached stable motility from the age of 3 years old and forward. While the sperm concentration was stable normal and not affected the age of bulls, ranged from 1004 ± 289 to 1124 ± 306 (x106) sperm / ml. When the body weight was grouped as low, medium and high, the semen volume, sperm motility and sperm concentration per ml were significantly increased in all parameters. The semen could be collected continuously by months over year although the ejaculate volume and sperm motility were significant different three monthly might be due to the different climate and quality of consumed feed. The higher semen production was during the period of October – December and the lowest was from January to March. The semen production during the periods of April – June was similar to those from July – September. In conclusion, by excluding the feed and feeding factors, the semen production of elite bulls at Singosari National Insemination Center (SNAIC) were affected by age of bulls, body weight and months of semen collection.

Abstract
Reproduction in most important factor determining the effectivity of the goat farming trough the success of increasing number of animal in the herd or population. Reproduction performance is the phenotypic trait and those more influenced by management factor than by genetic factor. However, the Indonesian local goat was reported having high adaptability and tolerance to the tropical climate with high environmental daily temperature and humidity, low quality feed and some parasites. This paper reviews the reproduction performances of local goats under intensive management in the company and when those kept by small holder farmers. The data analysis showed that the reproductive parameters in intensively were higher than those of managed by small farmers (Service per Conception, litter size, pre-weaning mortality, and birth weight), the weaning weight were similar in both groups, while Days Open and Kidding Interval were significant lower in intensive farming than those maintained by small farmers as well as extensive farming. In conclusion, the reproduction performances that were controlled by good management system, good feeding and management will improve service per conception, litter size, birth weight, and reduced pre-weaning mortality, while on the other hands, the extensive farming increased the performances of days open and kidding interval time.

Published: June 2020

Abstract
Cellular structures are similarly identified as lattice structures or foam structures which are commonly constructed of ligaments. Cellular structures exist widely in nature, such as the coral, honeycomb, and the natural bones. Cellular structures are also manufactured and used in various applications such as honeycomb bumper structures and truss bridge. Ti6Al4V is one of the most commonly used titanium alloy and is applied in a wide range of application where low density very good corrosion resistance are necessary such as direct manufacturing of part and prototypes for racing and aerospace industry, biomechanical application such as implants and prosthesis, marine application, chemical industry, and gas turbine. This paper investigates the mechanical properties of Ti6Al4V lattice structures fabricated by additive manufacturing, also known as 3D printing. The samples are fabricated by selective laser melting (SLM) using titanium alloy (TI6Al4V). Four factors were selected to determine its influence on the Young’s modulus and compressive strength, which is strut size, strut shape, unit cell size, and porosity. All the samples categorize to six groups by its design volume porosity obtained from CAD file. Solidwork design software was used in this study. The influence was shown in a comparison graph. Detailed characterizations of compression test were conducted and reported. The built structures have a Young’s modulus ranging between 0.01 and 1.84 Gpa. Porosity was realized to play an important role in determining the Young’s modulus and compressive strength.

Published: June 2020

Abstract
Since several past decades, many studies prove that the statistical or signal features extracted from the sound acquired from laser welding process was significantly giving information on the weld condition. However, a considerable amount of studies were only emphasizing on the use of common statistical features in which it is restricted to some limitation when dealing with non-stationary random sound signal. In this particular work, the main aim was set to detect the irregularities along the weld bead by way of implementing the L-Statistic analysis on the acquired sound during pulse mode laser welding process. To achieve the goal, pulse mode laser welding have been done onto 22MnB5 boron steel plate in butt joined configuration. During the process, sound signal was acquired using microphone and further analyzed by extracting L-statistic features from it. According to the findings, among all the L-statistic features analyze in this study, L-Cv (scale) was found giving a significant indicator of the weld bead surface condition. Larger value of L-Cv was recorded at the point where the large underfill occurred. On the other hand, it was also found that the L-kurtosis values could give remarkable information on the existence of the irregularities on bead width and depth. Hence, it could be drawn into conclusion that the irregularities on the weld bead during the pulse mode laser welding could be detected from the appropriate L-statistic features of the acquired sound signal. The finding in this work was believed to be essential in enhancing the capability of acoustic sound method to be developed as online monitoring system for pulse mode laser welding process.

Published: June 2020

Abstract
Instead of mineral oil, water hydraulic uses seawater or tap water as the medium in its operation. Most of the materials tested have some reaction towards friction and water lubrication. While hydraulic system may be advantaged by natural materials, the related work remains unestablished. In present work, the tribology of bone in contact with stainless steel is computationally simulated. The materials combination used in this study were metals (316L stainless steel and Al2O3) and natural bone. Increase in contact pressure is found to be contributed by the extent of sliding distance. Wear depth is also subsequently increased in this manner. Higher normal load applied on the model exhibits higher contact pressure in between metal-bone pair model.

Abstract
Acute kidney injury (AKI) is common in critically ill patients and often associated with higher mortality. It is commonly diagnosed using plasma creatinine, a fluid excreted by glomerular filtration. In this study, we analysed the highly nonlinear and complex behaviour within human systems of estimating glomerular filtration rate in critically ill patients to estimate AKI outcome by developing an application program that describes various numerical mathematical models estimated glomerular filtration rate (eGFR). The program was developed to collect numerous clinical patient data and perform computations of the governing equations that may provide clinicians with rapid estimation of GFR which allow prediction of recovery or worsening of renal function at bedside. Data collection using the application program was conducted at the intensive care unit in Kuantan, Malaysia from January to August 2016. It was found that the eGFR by CKD-EPI shows the best correlation with kinetic GFR (keGFR) equations compared to other mathematical methods for Malaysian ICU patients. It is endeavoured that more patient data would be collected using this mobile application, to develop a more accurate GFR estimation model suitable for Asian populations since creatinine based equations are often derived based on white populations.
