The study examines Drivers of the Adoption of E-Government Services in the deliverance of Healthcare services in Federal Health Institutions. the study adopts drivers such as perceived Usefulness and perceived ease of use and their influence in the adoption of E-Government Services in the deliverance of Healthcare services in Federal Health Institutions. The survey research design was adopted in collecting 400 sample from administrative staff of the University of Calabar Teaching Hospital, Calabar using the purposive sampling. The sample size was determined using Taro Yamane sample size determinant technique. The questionnaire was the instrument of data collection. Data collected was analyzed using simple regression analysis at 0.05 confidence level. Result revealed that Perceived usefulness significantly influence the adoption of E- Governance Services in the deliverance of Healthcare services in Federal Health Institutions (R-value of 0.176a). Also result revealed that Perceived Ease of Use significantly influence the adoption of E- Governance Services in the deliverance of Healthcare services in Federal Health Institutions (R2 –value of .018). based on this result the study recommends amongst others that there is need for efforts to improve this basic infrastructure by the government should be strengthened both in terms of coverage and quality

Gambir contains functional compounds that are included in the class of polyphenol compounds. The polyphenol compounds in gambir are mainly catechins, a natural substance that has antioxidant properties. The purpose of this study was to obtain catechin compounds from Gambir extract, to determine the solvent concentration and the right extraction temperature to obtain catechin compounds in Gambir, and to increase the selling value of Gambir latex in the Farmer community. To get the results of catechins in Gambir, this research was carried out using the infundation method. The yield of the extract was mostly found at a solvent concentration of 45% ethanol, a temperature of 105 oC and a time of 3 hours, namely 81%. Qualitative test using FeCl3 reagent can be seen that in the filtrate extracted from gambir there are catechins which show a blackish green color when dropped with FeCl3

Talent management is a factor that determines success in the business environment because talent management requires quantitative and qualitative skills. This study aims to implement the certainty factor (CF) method of an expert system for employee development talent management. This research using a certainty factor (CF) method to design an expert system framework. Due to the focus on our research aim, we provide a certainty factor calculation with mathematical modeling for calculating talent management employee development in X Company. The confidence level is 93.55% for a recommendation of not promotion of the job; for 52.38% is a recommendation that can be proposed for promotion, but HRD will evaluate in some time; for 98.73% is a recommendation for promotion of the job. We used CF calculation that can provide the level of confidence (in %). The calculation of the certainty factor (CF) method can be used for recommending job promotion in some companies.

Electroplating uses aluminum material, where it’s easy to obtain, lighter, and cheaper than other metals. The research goal was to determine the ability of the electric current to power aluminum (Al) coated with silver (Ag) by the electroplating method, to determine the effect of the magnitude of the electric current and the length of time the coating process took on the weight of Al coated with Ag and to determine the strength of the metal Al after tested using Brinnell test. The method used is to compare pure Al and pure Al coated with Ag by electroplating at different currents to determine the effect of the electroplating process. A Brinnell test was carried out to determine the hardness of the Al material after electroplating. The results are the amount of current that flows during the electroplating is directly proportional to the thickness of the electroplating layer attached to the Al surface. If the electroplating process uses a large current, the attached layer will look rough and not smooth, which also affects the material testing by using the Brinnell method. The Brinnell test proves that the hardness value of the Al material is directly proportional to the thickness of the layer.

Energy is something that people need every day. One of the energies that are glorified to meet people's energy needs is electrical energy. The need for electrical energy in Indonesia continues to increase in line with economic growth and the increasing population. One of the components of electric power that is useful for delivering electric current to transmission networks is a substation. With the feasibility of techno-economic, it is possible to know the feasibility of the quality of an electric power system based on financial analysis. This paper provides a mini-review of the techno-economy of substation electricity and its maintenance in several regions in Indonesia today. The research stages consist of literature study, identification of article titles, article abstract screening, complete article selection, and mini-review reviews. Several studies are still not widely applied to the calculation of the cost of energy consumption to customers. In addition, the basic cost of providing electricity, the profit from electricity sales, and the payback period method need to be improved in research related to the techno-economic analysis of electrical energy. It is important to do this to determine the potential feasibility and the estimated advantages and disadvantages of an electric power system.

Humans are basically inseparable from education in carrying out life. The implementation and development of educational studies must also be adapted to the conditions and social situations that exist in the community. The main focus of Goal 4 on Sustainable Development Goals (SDGs) is to provide inclusive quality education or to ensure everyone has an equal opportunity to get good quality of education. In fact, Indonesia is still struggling in the quality of teacher issue. In the school year of 2019/2020, there are 8.98% unqualified teachers and headmasters on primary school level, 6.16% on junior high school level, 10.07% on senior high school level, and 10% on vocational high school level. Cumulatively, from primary school level to vocational high school level, there are 247.462 unqualified teachers and headmasters in Indonesia. This is a serious problem, considering that teachers are important component in determining the quality of education itself. In this research, UI/UX design prototype of learning web application named “IdeIn” was developed using Design Thinking method that consists of empathize, define, ideate, prototype, and test stages. The main focus of this learning web application is to provides an opportunity to the whole community to support education in Indonesia by conducting online classes.

In recent years, the process of cellular manufacturing and group technology have received a lot of attention and popularity in many developed countries. By applying Group Technology (GT), many benefits of flow-line production can be attained in a batch production system. GT improves material handling significantly by reducing material flow time, distance, and setup times. In this paper, an earnest investigative attempt was made to provide valuable information regarding the use of Group Technology by applying to a real world jobshop system. The proposed GT model has the flexibility of choosing the number of cells required, which is very useful in examining different manufacturing cell configurations; or in case the workshop or factory prefers a certain number of work cells. The GT model results were found satisfactory and superior to other techniques in some cases.

In recent years, with the strong development of the industry, it has created a competitive market. To be able to stand and survive requires businesses to create their own charisma based on the products they create must have the quality, cost and speed quickly. To do that requires businesses to have proper production strategies. Especially for the garment industry, which has a lot of waste in the production process that needs to be eliminated. This study focuses on the construction of standard time sets and standard activities to help eliminate wasted time on hand movements and time spent by workers. The result ca be used to develop the standard operation procedures of the production process.
