Abstract

Hipertensi atau darah tinggi merupakan kondisi tekanan darah yangmeningkat secara berkelanjutan melebihi batas normal. Hipertensi dapatmengakibatkan terjadinya gagal ginjal yaitu menurunnya fungsi ginjal yang ditandai dengan nilai bersihan kreatinin dan ureum yang tinggi. Pasien gangguan ginjal harus mendapatkan dosis obat berdasarkan perhitungan bersihan kreatinin ginjalnya untuk menghindari terjadinya toksisitas obat akibat kegagalan ekskresi oleh ginjal. Penelitian ini mengaplikasikan bahasa pemograman Visual Basic.Net (VB.NET) dalam perhitungan dosis obat individual berdasarkan rumus farmakokinetik untuk pasien hipertensi komplikasi gagal ginjal di Rumah Sakit Dr. Pirngadi Medan. Berdasarkan aplikasi Visual Basic.Net (VB.Net) perhitungan dosis obat pada pasien hipertensi diperoleh 6 dari 9 kasus penggunaan ranitidin, 8 dari 13 kasus penggunaan kaptopril, dan 2 dari 2 kasus penggunaan digoksin. Aplikasi Visual Basic.Net untuk menghitung dosis obat individual mudah digunakan dan sangat membantu dalam menetapkan dosis obat pada pasien yang menderita gangguan ginjal.

Abstract

This research aimed to determine the development of the exchange rate, the extent to which Indonesia can repair and recover the economy after the financial crisis of 1998 to the present. The data used in the form of quantitative data, namely exchange rate, inflation rates, interest rates, exports and imports from 1998 to 2012 to process the data used SPSS version 20 and helps by computer. Based on estimates obtained significant value for the inflation of 0,260 or 0,260 > 0.05, this means that the rate of inflation but no significant effect on the exchange rate on the dollar value of the United States in 1998-2012. While the value for the interest rate obtained at 0.963 or 0.963 > 0.05, this means that the interest rate but no significant effect on the exchange rate on the dollar the United States in 1998-2012. As for the value of exports and imports respectively show the figure of 0.174 or 0.174 > 0.05 and 0.123 or 0.123 > 0.05, which means that exports and imports, but no significant effect on the exchange rate on the dollar value of the United States in 1998-2012. Based on calculations, the significant value of 0.112 or 0.112 > 0.05 (5%) which means that independent variables are inflation, interest rates, exports and imports together, but no significant effect on the exchange rate on the dollar value of the United States. R value of 0.705, which means that the correlation between the variables of inflation, interest rates, imports and exports to the exchange rate is equal to 0.705. In this case there is a close relationship since the value of R approaches 1, while the coefficient of determination or R Square (R2) of 0.497, which means the percentage contribution of variables influence inflation, interest rates, imports and exports to the exchange rate on the dollar value of the United States amounted to only 49.7%, while the remaining 51.3% is influenced by other variables not included in this research.  Keywords : Financial Crisis, Exchange Rate, Inflation, Interest Rate.

Abstract

The drug is a substance that when inserted into the human body in the right measure will cure the disease but when the measure exceeded it will happen poisoning. The dose of a drug that is indicated in Pharmacopoeia Indonesia consists of maximum dose is prevalent and just based on age (adult or children) without regard to the patient's kidney condition. The condition of patients with impaired kidneys cannot receive doses of common good, necessary adjustments to the dose pharmacokinetics based on calculations with numbers of serum creatinine. Drugs with a narrow therapeutic range and nephrotoxic can aggravate the condition of kidney patients. Therefore, this research aims to build a visual basic.net application of individual dose calculations based on the pharmacokinetics formula. Visual Basic.net programming language is one that can be implemented into the computer in either a State of its own (standing alone) or network (network).

Abstract

Artificial Intelligence is a part of computer science that studies how to make computers able to do work like humans do. The horse checker on a chess board has a movement that resembles the letter L. This chess checker is one of the pieces that is very difficult to move and is often the most dangerous checker if you don't pay close attention to each movement. The simulation of this problem provides an n x n chessboard. The goal of this problem is to move a horse from a certain position on the chess board to the desired goal position by simulating all the shortest possible movement solutions to get to that goal position. This problem is also one of the classic problems in artificial intelligence (AI). Solving this problem can use the help of production systems and tracking trees

Abstract

Legacy of Sisingamangaraja XII" is an educational game designed to enhance young people's understanding of the struggle of Sisingamangaraja XII, an Indonesian national hero who fought against Dutch colonialism in the 19th century. This research employed the ADDIE model (Analyze, Design, Develop, Implement, Evaluate) to ensure the game's effectiveness. Developed using RPG Maker MV and the Finite State Machine (FSM) method, the game successfully increased interactivity by regulating the dynamic behavior of Non-Playable Characters (NPCs), enabling dialogues, providing clues, and responding to player actions realistically. The results of the evaluation showed that 81% of respondents felt positive about their gaming experience, 82% experienced an increase in historical understanding, and 84% considered the game to be an effective learning medium. FSM proved to enhance the depth of interaction and realism in gameplay, providing an immersive and enjoyable learning experience. This research concludes that "Legacy of Sisingamangaraja XII" is an effective and innovative interactive learning tool with potential for application to other historical materials.
