Investment Portfolio Optimization in Indonesia (Study On: Lq-45 Stock Index, Government Bond, United States Dollar, Gold and Bitcoin)

/in /by

In forming their portfolios, investors should analyze the risk and return of each investment instrument. This is aimed at preventing investors from speculating and gambling with their investments. Conducting an investment portfolio optimization study on LQ-45 stock index, government bond, USD, gold, and Bitcoin can provide valuable insights due to unique market characteristics in Indonesia. This research analyzes the formation of investment instruments over the last 60 months, specifically from January 2018 to December 2022. The research method used in this study is quantitative research aimed at selecting several investment instruments for a portfolio in Indonesia. The portfolio aims to minimize risk and maximize return using the Markowitz method, also known as the optimal portfolio. To fulfill the objectives of this research, data on the prices of each instrument are required. An optimal portfolio can be obtained by combining two instruments: 18% bitcoin and 82% gold. This optimal portfolio can achieve an expected return of 1.29% with a risk level of 5.15%. Considering a risk-free rate of 0.375%, this portfolio forms a slope of 0.1775, which is the largest slope formed between the combination of risk-free instruments and risky portfolios. Investors should allocate their funds more wisely, considering not only the highest return but also the associated risk. High returns often come with high risks, so investors need to assess the risk-return trade-off before making investment decisions.

/in /by

Tourism has economic effects as well as political and social effects, but its economic effects are more than social and political effects. Tourism is closely related to the economic growth and development of countries and creates better job opportunities and an increase in income. Therefore, tourism is a significant cause of economic development, the economic value of which increases with each passing day. It can make a positive change in the economic and social situation of the countries. The results of the research indicate that, along with increasing the income of developing countries, the development of tourism has also created suitable activities, and while reducing the level of poverty, it has prevented the immigration of young people and attracted foreign investment. The findings of the research show that one out of every nine working people in the world is engaged in tourism-related matters.

Enhancing Car Showroom Profitability through K-Means Clustering for Customer Segmentation

/in /by

Indonesia is known to be one of Southeast Asia’s largest markets for used cars. Used car showrooms in Indonesia are numerous and varied, some focus on one car brand, some focus on the lower middle class, some focus on the upper middle class, and some provide all types of cars. One of them is PQR Showroom, Even though PQR Showroom was able to generate such a great amount of sales, the profits generated by the PQR showroom are not proportional to the amount of capital invested.

To increase the profit, we proposed the solution using descriptive analytics and prescriptive analytics using K-Means. We also carry out simulations by comparing sales in existing years with the results of the descriptive and prescriptive analytics that have been made for the expected profit.

The results show that the simulation comparison with the data we have obtained from descriptive and prescriptive analysis gives the best-expected profit compared to the initial sales results at the PQR Showroom.

It shows that the data using descriptive and K-Means is great than before. The fastest cars that have been sold is LCGC and the most wanted car is MPY Toyota Avanza and the best profit that can generate is SUV Toyota Fortuner.

Accelerating the Digital Transformation in Bank XYZ

/in /by

In current fast-paced and highly competitive business climate, organizations progressively recognize the necessity of embracing digital transformation. Due to developments in technology and the unprecedented effects of the COVID-19 pandemic, the banking sector is one of the sectors that has experienced significant disruptions. Digital transformation has become increasingly crucial for banks to remain competitive, sustain business continuity, and meet shifting customer demands. However, the mere adoption of digital technologies is insufficient. In order to adapt with the digital era, it is essential to assess the effectiveness of digital transformation initiatives. As Bank XYZ started and continued to undergo their digital transformation, the company has measured its digital maturity the prior year and the result leaned toward the “Digital Master” stage. However, there could be indications that the digital transformation has not been implemented optimally. Using the Digital Mastery and the Digital Transformation Compass framework, the research emphasizes the importance of accelerating digital transformation for Bank XYZ through digital maturity and digital transformation evaluation to analyse its digital transformation progress while recognizing areas for improvement.

The result shows that the current digital maturity result display the same trend as the year prior that the company has reached the “Digital Master” stage affected by the current composition of senior executives and the availability of strategic agenda that drives the digital transformation within the company. However, when the digital transformation was analysed further, the transformation progress is still in the moderate level. It can be concluded that that while initiatives have been implemented, there are improvements need to be made with the aim of advancing Bank XYZ’s digital transformation process. This research proposes business solutions that focuses on enhancing synergies withing the organization to accelerate the digital transformation.

Charge Transfer and Optical Characteristics of cyclopenta-diene based Oligomers

/in /by

1,4-bis(2-(cyclopenta-1,3-dien-1-yl)ethyl)cyclopenta-1,3-diene [CCD] is one of the interesting oligomer with high charge carrier mobility and chemical stability. Based on the density functional theory (DFT), the electronic characteristics of four CCD molecules with various hetero atom substituents are investigated. The electronic of four CCD molecules with different hetero atom substituents are explored based on the density functional theory (DFT). The effects of substituents on the molecular structure, molecular orbitals, ionization energies, electron affinities, reorganization energy and crystal packing are analysed in detail to clarify the structure-property relationship of the studied molecules. The different crystal packing arrangements and intermolecular interactions of the studied molecules lead to differences in transfer integrals when introducing different substituents to the CCD molecule.
