Abstract

The interaction model dynamics between tumor and viruses based on the interaction phenomenon between the three populations, namely: population of uninfected tumor cells, tumor cell population infected with the virus and the virus population. This study aimed to see the interaction between non-infected tumor cells, tumor cells infected with viruses and viruses, so it can be modeled using virotherapy treatment of measles virus in mouse lung tumors. Model parameters obtained from experimental data. Numerical Solution of the models suggest that the dose of the virus play an important role in determining the outcome of tumor therapy. Tumor growth can be slowed by using this virotherapy, but the tumor can not be killed as a whole. Keywords: model dynamics, virotherapy, measles virus, mouse lung tumors

Abstract

There are several types of treatment options that can slow the progression of HIV that can be offered if the number of CD4 + cells has been known for certain, one treatment is by immunotherapy with interleukin-2 (IL-2). This type of treatment is to increase the immune system that can help the body fight against the infection itself. Efforts to raise an immune response would be appropriate to reduce the amount of virus. This brings new hope for treatment of HIV infection and the type of treatment is being researched. Interleukin-2 (IL-2) is most of the cytokines which are proteins made by the body. T-helper cells, a type of white blood cells, produce IL-2 when they were stimulated by infection. In this study, a model of HIV disease progression than individuals not treated can be expressed in a mathematical model, and also expressed immunotherapy model to see the dynamics of viral populations and the population of CD4 + T cells from HIV disease based on ordinary differential equation (ODE). This study aims to calculate the numerical solution immunotherapy mathematical model in HIV infection and a mathematical model to predict the outcome of immunotherapy treatment strategies in HIV infection. Keywords: HIV, CD4 + T cells, immunotherapy, mathematical modeling

Abstract

Telah  berhasil  dilakukan  uji  kinerja  empat  jenis  sensor  suhu  dan  kelembaban  yang  tersedia  di pasaran,  yaitu  DHT22,  BME280,  SHT31  dan  DS18B20.    Sensor  tersebut  dihubungkan  dengan WeMos  D1  R1  ESP8266  yang  bertugas  untuk  mengelola  dan  mengirimkan  data  ke  platform internet  of  things  (IoT)  ThingSpeak.  Pengiriman  data  menggunakan  protokol  message  queue telemetry transport (MQTT) yang berdaya rendah (low-power) dan dapat diandalkan (reliable). Laman web ThingSpeak menampilkan grafik suhu dan kelembaban masing-masing sensor. Data suhu dan kelembaban tersebut dibandingkan dengan thermohygrometer sebagai referensi. Hasil pengujian menunjukkan bahwa sensor mampu mendeteksi perubahan suhu ruangan dengan nilai pembacaan  yang  tidak  berbeda  jauh  dengan  referensi.  Secara  umum,  semua  sensor  bekerja dengan  cukup  baik  yang  ditandai  dengan  koefisien  determinasi  yang  cukup  tinggi  pada  kurva kalibrasi yaitu lebih dari 0,94 untuk suhu dan 0,96 untuk kelembaban.
