Judul: Analysis of Contractor Business Development Strategy (Case Study: PT Tri Manunggal Karya)
Abstrak: Meningkatnya persaingan bisnis konstruksi di Indonesia membuat PT Tri Manunggal Karya (PT TMK) harus berinovasi untuk bertahan di industri konstruksi, salah satunya dengan memiliki strategi bersaing untuk pengembangan bisnisnya. Sebagai perusahaan induk, strategi yang tepat sangat dibutuhkan oleh PT TMK untuk membuka peluang pasar bagi perusahaan dan anak perusahaannya serta menghindari risiko kegagalan bisnis dan kerugian finansial. Penelitian ini bertujuan untuk menganalisis faktor internal dan eksternal serta menganalisis strategi prioritas pengembangan PT TMK. Metode analisis yang digunakan adalah analisis Internal Factor Evaluation (IFE), analisis External Factor Evaluation (EFE), analisis Strength, Weakness, Opportunity and Threats (SWOT), dan analisis Analytical Hierarchy Process (AHP). Hasil penelitian menunjukkan bahwa kondisi internal PT TMK berada pada posisi yang tinggi dalam memanfaatkan kekuatan dan mengatasi kelemahannya, sedangkan faktor internal berada pada posisi sedang dalam merespon peluang dan ancaman. Peluang dalam industri perusahaan yang dapat disimpulkan adalah pembangunan infrastruktur dan sumber daya manusia yang kompeten masih terbatas di wilayah Indonesia Timur. Ancamannya adalah kondisi pasca pandemi dan teknologi konstruksi yang berkembang pesat. Hasil Analytical Hierarchy Process (AHP) menunjukkan strategi akuisisi unit bisnis baru dianggap sebagai prioritas utama, diikuti dengan ekspansi ke luar Pulau Jawa., Increasing competition of construction business in Indonesia forces PT Tri Manunggal Karya (PT TMK) to innovate to survive in the construction industry. One way is by having a competitive strategy for its business development. As a holding company, a proper strategy is highly required by PT TMK to open up market opportunities for the company and its subsidiaries and to avoid the risk of business failure and financial losses. This study aims to analyze internal and external factors and analyze the priority strategies for PT TMK development. The analytical methods used were Internal Factor Evaluation (IFE) Analysis, External Factor Evaluation (IFE) Analysis, Strength, Weakness, Opportunity, and Threats (SWOT) Analysis, Analytical Hierarchy Process (AHP) Analysis. The result shows that the external condition of PT TMK is in a high position in responding to opportunities and threats. Its internal figures are in a strong stand in utilizing strengths and overcoming its weaknesses. Opportunity in the company's industry can be concluded because infrastructure development and competent human resources are still limited in the Eastern parts of Indonesia. The threats are post-pandemic conditions and fast-growing construction technology. The result of the Analytical Hierarchy Process (AHP) shows the strategy of acquiring new business units is considered as the main priorities, followed by expansion out of Java Island.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
