Abstract

Some literature studies showed that to get a better career in the contemporary work environment, students need to develop critical thinking skills, problem solving, emotional intelligence, teamwork, and communication. There is, however, in fact a doubt that educational institutions do not sufficiently provide the needed skills to cope with work competition. While World Economic Forum 2020 indicated about 15 skills that have increasing demand in workplace, educational institutions show slow responses toward the demand which means that students might obtain these skills in the context of non-academic learning process. Some of these skills such as critical thinking analysis, complex problems solving, and analytical thinking and innovation has become the prerequisite skills for the today career. Thus, students need to prepare themselves by increasing the knowledge and skills needed in the future. In virtue of the work demands, educational institutions need to design their curriculum in accordance with the work environment as to be able in bridging a transition from school to work environment.

Abstract

In this competitive business era, Klinik Bunga Melati (KBM) has changed its business and management strategies 3 times in the last 2 years with the aim of adjusting internal and external conditions in the health sector and make KBM superior to other competitors. KBM expects the development of technology that can be applied efficiently and integrated between KBM internally. In 2018, KBM teamed up with the Badan Penyelenggara Jaminan Sosial (BPJS) Kesehatan. In this regard, BPJS provides a Health Facilities Information System (HFIS) with the aim of making it easier for health units to make claims. But the leader of the KBM considers HFIS not suitable to be implemented in the KBM Welirang Branch. The KBM Welirang Branch staff must do 2x recapitulation of patient medical records every day. There are quite a lot of variables in HFIS besides self-data, staff must also write data related to diagnosis, details of drugs used, drug costs, and doctor's fees. Based on the KBM leaders interview, this is considered to be very time-consuming and costly because HR has to work 2x more and patients need more time to get action. HOT-Fit method is considered suitable for this research because this model can provide an explanation and provide an evaluation of the application a system in the field of health services from human factors (human), technology (technology), organization (organization) and net benefits. The output of this research is an analysis of aspects that need to be improved and the match rate of HFIS implementation in the KBM Welirang.

Abstract

Isolate α-mangostin (1) is a phenolic compound derived from oxygenated and prenylated xanthones and major compounds obtained from the fruit peel of G. mangostana Linn., Which is stated to have inhibitory activity against α-glucosidase enzymes, serves to determine the antidiabetic activity resulting in IC50 value of 29,92 µM, is of the nature moderate to positive control (acarbose) with an IC50 value of 4.55 µM. A modified compound of α-mangostin (1) with acetic anhydride obtained by 3,6-di-methyl ester-α-mangostin (2) derivative showed the inhibitory value of α-glucosidase (IC50 13,89 μM), this value is better than the activity inhibition of α-mangostin (1), but not as active as the positive control value of the acarbose compound. The separation process to obtain α-mangostin isolates from the fruit peel of G. mangostana Linn was obtained by maceration method with ethyl acetate solvent, followed by refraction using a vacuum liquid chromatography (KCV) method over silica gel (Merck 60 G) and eluted using eluent (n-hexane: ethyl acetate) with increasing polarity, to produce as much pure crystal (21.66 g), yield (24%). While the structural characterization of the two compounds was carried out using UV-Vis, IR, HRESIMS, 1H-NMR and 13C-NMR spectroscopic methods, the antidiabetic testing was carried out using the α-glucosidase enzyme inhibition method.

Abstract

Various reasons underlying the company's owner to Go Public processes such as increasing the company's capital, diversifying shares, overcoming lending constraints. Whatever the underlying reasons, Go Public decisions always have an impact on the company's finances and operations. There is a possibility for companies to not be able to manage funds from the Go Public process, causing a surplus of equity and an impact on decreasing company performance. This research was conducted to determine the impact of Going Public on company performance in terms of profitability. This study uses a purposive sampling technique to produce 3 sample banks that conduct an IPO in the period 2009- 2012 with the BOOK Bank category 2. Post-Go Public company performance is analyzed in terms of profitability using the financial ratios of Net Profit Margin ( NPM) and Gross Profit Margin (GPM). Hypothesis testing in the form of a paired t test was conducted on Net Profit Margin (NPM) and Gross Profit Margin (GPM) for the period of 4 years before and after going Public. The results of this study are expected to find out whether the process of Going Public has an impact on company profitability. In addition, the company's ability to perform cost efficiency can be measured through the use of the ratio of Net Profit Margin (NPM) and Gross Profit Margin (GPM).

Abstract

Microbial contamination, instability in production yields and cell lines are the challenges that must be faced by any pharmaceutical biotechnology industry when conducting cell culture as one of the stages of its production process. In the past, Company X has experienced twice contamination cases during cell culture process for its recombinant protein products. As a result, Company X suffered financial lossess at approximately 3.05 billion rupiah and resulted in disruption of the stock of recombinant protein drug which are the active pharmaceutical ingredient for most of injection products. Therefore, an effective mitigation strategies are needed to manage any potential risks in the cell culture process. This study aims to design a risk mitigation strategy for risk in cell culture process by using House of Risk (HOR) method. There are two HOR matrices used in this study. HOR1 is used to determine which risk agents should be prioritized for prevention. In HOR2, several effective risk management strategies will be chosen. There are 40 risks events and 31 risk agents identified. Based on risk assessment results and applying Pareto Chart analysis there are two risk agents selected. Five proactive actions to mitigate these risks are proposed. They are training and personnel qualification program periodically, changing workflow become more efficient and convenient, more detailed revision of related documents, changing manual process to semi-automatic process gradually and additional person on each team as a verifier for double-checking.

Abstract

The new policy issued by PT Pupuk Indonesia regarding the change of the responsible party for the procurement and the distribution of subsidized NPK fertilizers affected the subsidy allocation for PT Petrokimia Gresik, as the only company to conduct the procurement and distribution of the subsidized NPK fertilizer. It is now partially charged to the other holding members such as PT Kujang Cikampek, PT Pupuk Sriwidjaja, and PT Pupuk Kaltim. Also, all members of PT Pupuk Indonesia should face the reduction of subsidy allocation from Indonesia Government. PT Petrokimia Gresik also have to deal with Phonska V project plan in order to increase capacity of NPK fertilizer. Those policies are most significantlty impactful to the decrease of subsidy allocation in West Java. Besides, Central Java, a branch area of PT Petrokimia Gresik which has the biggest number of total capacity and fixed cost, should reevaluate the number and location of the buffer warehouse. This paper is aimed to explain the methodology using Mixed integer Linear Programming (MILP) in determining the optimal number and location of buffer warehouse in West Java and Central Java in response to the policies and the project plan. Firstly, the distribution system of NPK subsidized fertilizer are described. Next, previous researches about MILP and forecasting method applied in distribution system problem is explained. After that, related data and several conditions that are applied based on actual situation are shown. It can be deducted that MILP is an optimal method for the evaluation as it fits to the characteristic and condition of distribution system in PT Petrokimia Gresik.

Abstract

Surabaya City has the highest activity and density in East Java. This situation affects physical and psychological health. Studies are stating that not exercising regularly is more dangerous than smoking. Therefore, public awareness of the importance of exercising must be increased for the health and national development. In stimulating people to be interested in visiting sports facilities is to apply the biophilic design approach. Restoring the essence of human relations with the nature can be a solution to increase enthusiasm in activities, especially sports in the city of Surabaya, that needs more natural elements. In biophilic theory, several elements can be used as design approaches, one of which is natural shapes and forms. According to Kellert's theory, the natural shapes and forms approach can be applied in 11 elements but these elements are global. By applying the theory of environmental perception, specific natural elements will be obtained with the interests of the people in Surabaya. The analysis results of the design with force-based framework method are specific design criteria for the design of the fitness center with natural shapes and forms approach. This can increase the interest in training and restore the physical and psychological health of its users.

Abstract

When a product is launched, it's always been expected by the company that the product is going to be sold out in the market. But, after three years of selling XYZ colocation data center services, the sales of this product still hasn't achieve its target. Therefore, an evaluation is needed to know how costumers value the product in the market and what's needs to be done to improve its value. XYZ Data Center Management has conducted a preliminary analysis through discussion with customers, a comparative study with competitors, and discussion with internet service provider association. It's concluded that there is quality in XYZ Data Center, both in features and services that don't satisfying enough. Further analysis then conducted with Quality Function Deployment or QFD as a research method. The reason behind the use of QFD is because of its ability to identify what customers want, and translate it into the company's need in terms of technical responses. The result obtained from this research is the attributes that customers need and the technical responses required to answer it. Examples of attributes are the availability of the working room, the availability of site visit procedure, the accuracy of time needed for installation, etc. And for technical response, the examples are making a portal for trouble handle monitoring in integration with a call center, an improvement on IT Hall layout building a portal for installation monitoring, etc.
