Abstract

The lungs are the main organ in the human respiratory system which is located in the chest cavity and consists of a pair. The lungs are a vital organ that greatly influences the body's health, because it has the function of maintaining the body's acid-base balance, removing carbon dioxide that the body does not need and water vapor. Smoking is the main cause of lung disease, in 2020 based on the World Health Organization (WHO) report, it is estimated that 10 million people suffer from lung disease worldwide. This research uses the Naïve Bayes classification algorithm to obtain a prediction model that can predict lung disease patient data. This research aims to obtain accuracy values ​​using the Naïve Bayes algorithm. The data used in this research was obtained from Kaggle which contains 469 data with 14 attributes in it. RapidMiner is used as a tool to test the patient dataset used to produce a prediction with an accuracy rate of 99.9% risk false (no risk of having lung disease).

Abstract

Tenaga penjualan adalah aset paling penting bagi sebuah perusahaan. Pengembangan kompetensi tenaga penjualan tidak dapat sepenuhnya dievaluasi karena kompleksitas keterampilan yang langsung diperoleh dan digunakan. Kesulitan dalam menentukan kriteria penilaian yang sesuai untuk mengevaluasi kinerja tenaga penjualan di perusahaan tidak cukup hanya menggunakan persepsi manusia oleh manajemen. Hal tersebut karena penilaian dan persepsi manusia terhadap kriteria kualitatif selalu subjektif dan tidak tepat. Dalam menentukan beberapa kategori kriteria, diperlukan teknik kuantitatif dan kualitatif sebagai sarana pengambilan keputusan dalam organisasi. Penelitian kuantitatif menghasilkan data dalam bentuk angka, sedangkan penelitian kualitatif cenderung menghasilkan data yang disajikan dalam bentuk narasi dan teks. Dalam penelitian ini, diusulkan model MCDM menggunakan metode Fuzzy AHP untuk mengevaluasi kinerja tenaga penjualan di departemen pemasaran perusahaan guna menentukan prioritas dan peringkat objektif dari alternatif. Hasil penelitian menunjukkan bahwa konsistensi rasio validasi menggunakan metode Fuzzy AHP pada kriteria kuantitatif diperoleh nilai 0,016 dan 0,015 untuk kriteria kualitatif. Kemudian analisis sensitivitas digunakan untuk mengidentifikasi dampak dari perubahan pada bobot relatif kategori kriteria kuantitatif yang nilainya diturunkan sebesar 3,85%, sehingga mempengaruhi penilaian secara keseluruhan. Secara spesifik pada pre-test dengan nilai akurasi sebesar 85%, sedangkan pada post-test menghasilkan akurasi yang lebih besar dengan nilai 95%, dapat diinterpretasikan bahwa evaluasi kinerja tenaga penjualan menggunakan metode Fuzzy AHP menghasilkan prioritas dan peringkat alternatif yang lebih objektif dan sangat sesuai untuk diimplementasikan di perusahaan. Analisis uji t-produksi nilai p adalah 0,000494 yang lebih kecil dari nilai alpha (0,05), menunjukkan bahwa hasilnya efektif.

Abstract

Vehicle queues formed in front of the gate of the ticket collection counter at STS Mall can cause problems and queue lengths that can interfere with other traffic movement systems. Therefore, it is very important to review the queuing system at the gate of the parking ticket collection counter at STS Mall. This study aims to examine the queuing system and determine alternatives to improve four-wheeled vehicle queuing services at the ticket collection counter to enter the parking lot at STS Mall. The main data needed in this study are vehicle arrival rates and counter service times. The data were obtained respectively using traffic enumeration methods and sampling observations, which were carried out at the entrance counter of four-wheeled vehicles and carried out on Saturdays and Sundays. The analysis method uses Queue Theory. The results of the analysis show that the number of counters 1 piece is still able to serve the current level of vehicle arrivals which gives a value of n ranging from 0.34 - 0.37 vehicles (( 1 vehicle) , q ranging from 0.08 - 0.06 vehicles (( 1 vehicle), d ranging from 8.2 - 8.6 seconds, and w ranging from 2.1 - 2.5 seconds. At an arrival rate above 600 vehicles / hour are no longer able to be served with the number of counters (N) as much as 1 piece without improving the queuing system

Abstract

The potential of solar energy in Indonesia is quite large as a renewable energy source, usually called solar panels or photovoltaic (PV) technology as a device capable of converting solar radiation into electrical energy. When solar panels operate, only about 15% of solar radiation is converted into electrical energy, while the rest is converted into heat. The intensity of solar radiation and the temperature of the surrounding air affect the voltage and current produced by solar cells. This condition requires a device that can regulate the temperature state of the solar panel. This study was conducted to overcome the heat problem in solar panels through optimizing the thermal properties of the cooling fluid by adding nano-sized SEM/EDS-tested particles to the W/EG base fluid, which is commonly called nanofluids, then making serpentine channels as a heat exchanger was also carried out. The experimental test process was carried out with a flow rate variation of 1 to 3 LPM and the inlet temperature was kept at 35˚C. The results showed that the highest cooling fluid flow rate was the most optimum condition. The Reynolds number shows that the heat transfer coefficient increases by 1011.72 W/m◦K, 1321.72 W/m◦K, and 2070.39 W/m◦K, respectively. The Nusselt number tends to increase as the Reynolds number of the nanofluid increases. An increase in Nusselt number indicates an increase in heat transfer coefficient, while Reynolds number indicates laminar flow of the coolant. Similarly, the pressure drop increases with increasing flow rate.
