Abstract

This paper examines the optimization of an Indonesian stock portfolio using two models: the Markowitz Model (Mean-Variance Model) and the Single Index Model. The data comprises historical returns of LQ 45 stocks from January 2016 to December 2021. The focus is on selecting stocks for the portfolio and determining their weights based on the two models. The study compares the performance of both optimized portfolios with the LQ45 Index benchmark, IHSG market, and each other using Sharpe and Treynor measurements. The paper tests whether the stock composition of the optimized portfolio from both models successfully and consistently generates a better performance in the future (1 January 2022 – 31 December 2022) and (1 January 2023 – 31 December 2023) compared to both LQ45 and IHSG. The results reveal a notable contrast in portfolio performance between 2022 and 2023. In 2022, both the Markowitz and Single Index portfolios exhibited remarkable returns, surpassing LQ 45 and IHSG. However, in 2023, both portfolios experienced substantial underperformance, with negative returns and unfavorable risk-adjusted metrics. These findings underscore the dynamic nature of financial markets and the need for continuous portfolio monitoring and adaptation. Investors are encouraged to reevaluate their portfolio strategies in response to changing market conditions. The study contributes valuable insights into the temporal variability of optimized portfolios and their sensitivity to evolving market dynamics.

Abstract

Human resource planning is an activity in human resource management that is used by organizations to ensure that they have the right amount and type of human resources. This research was conducted to determine the workload of goods inspection by aviation security officers in the security check point (SCP) 1 area, Terminal 3, Soekarno-Hatta Airport with a full- time equivalent method. The results showed that the amount of workload received by the executor is normal and excessive (Overload), for the workload of employees with supervisory positions is low (Underload). The addition of employees with executive positions is 1 person each gate, and the supervisor does not have an increase in the number of employees. The optimal number of aviation security employees at each gate security check point 1 to inspect goods is 1 supervisor and 5 executors.

Abstract

Pendidikan yang baik akan menciptakan sebuah sumber daya manusia yang unggul dan  membuat suatu negara menjadi maju. Selain itu, pemerataan  pendidikan juga menjadi salah satu faktor penting dan indikator terciptanya sebuah negara maju. Desa Tempur yang berlokasi di Kecamatan Keling Kabupaten Jepara tidak memiliki akses  pendidikan sekolah negeri karena akses yang jauh. Penerimaan siswa bersistem zonasi juga mengakibatkan semakin sedikit anak-anak yang dapat menempuh sekolah negeri. Perancangan Sekolah Menengah Pertama Negeri di Desa Tempur ini  merupakan salah satu solusi untuk mengatasi masalah tidak terjangkaunya sekolah negeri di Desa Tempur. Sekolah ini nantinya akan mempertimbang-kan aspek sosial, alam, dan ekonomi  untuk menciptakan bangunan minim pembiayaan mahal. Pada “Perancangan Sekolah  Menengah Pertama Negeri di Desa Tempur Jepara Dengan Pendekatan Konsep Sustainable  Architecture” ini, konsep yang yang digunakan akan meminimalkan dampak negatif bangunan  terhadap lingkungan sekitarnya. Langgam Arsitektur Neo- Vernakular diterapkan dalam bangunan ini sebagai respon desain dengan sosial budaya daerah setempat sehingga dapat menyatu dengan bangunan daerah sekitar. Data didapatkan dari studi literatur, studi kasus, dan studi lapangan. Pengolahan data membahas mengenai berbagai analisis, yakni analisis tapak, fungsi bangunan, pengguna, ruang, bentuk, struktur, sampai utilitas yang berpedoman pada sustainable architecture. Dan dari analisis tersebut menghasilkan sintesis atau konsep meliputi konsep tema, konsep bentuk, konsep tapak, konsep fungsi, konsep ruang, sampai dengan konsep utilitas.

Abstract

The market plays a crucial role in driving the economy and catering to the community’s needs. Pasar Baru Cikarang, located in the Bekasi Regency, serves as a significant market for the Cikarang area. Historically, Pasar Baru Cikarang was an impressive market that underwent construction and renovation in 1992, was completed in 1994, and commenced operations in 1995. However, the occurrence of looting events resulted in many traders resorting to street vending, leading to a decline in the market's appearance, which now appears shabby and untidy. This disrepair negatively impacts the primary area of Bekasi Regency, especially Cikarang, an ASEAN Industrial City. Considering the importance of having an architectural icon for an industrial city, the concept of industrial architecture becomes crucial. Industrial architecture embraces a minimalistic approach to final building finishing, making it an ideal choice for market buildings. Implementing this architectural concept in Pasar Baru Cikarang could revitalize the market's fading image and transform it into an iconic representation of the Industrial City. By emphasizing the industrial architecture concept in the renovation of Pasar Baru Cikarang, it is anticipated that the market's overall appeal will be enhanced, providing a boost to the local economy and reinstating its significance as a vital hub for the Cikarang area. This revitalization project can also contribute to the city's identity, further strengthening its position as an ASEAN Industrial City. Keywords: Cikarang Regency, Industrial City, Industrial Architecture
