Abstract

Medical imaging process has evolved since 1996 until now. The forming of Computer Aided Diagnostic (CAD) is very helpful to the radiologists to diagnose breast cancer. KNN method is a method to do classification toward the object based on the learning data which the range is nearest to the object. We analysed two types of cancers IDC dan ILC. 10 parameters were observed in 1-10 pixels distance in 145 IDC dan 7 ILC. We found that the Mean of Hm(yd,d) at 1-5 pixeis the only significant parameters that distingguish IDC and ILC. This parameter at 1-5 pixels should be applied in KNN method. This finding need to be tested in diffrerent areas before it will be applied in cancer diagnostic.

Abstract

Breast cancer is a health problem in the world. To overcome this problem requires early detection of breast cancer. The purpose of this study is to classify early breast cancer grades. Combination of physical parameters with k-nearest neighbor Method is proposed to detect early breast cancer grades. The experiments were performed on 87 mammograms consisting of 12 mammograms of grade 1,41 mammograms of grade 2 and 34 mammogram of grade 3. The proposed method was effective to classify the grades of breast cancer by an accuracy of 64.36%, 50% sensitivity and 73,5% specitifity. Physical parameters can be used to classify grades of breast cancer. The results of this study can be used to complement the diagnosis of breast mammography examination.

Abstract

An air pressure gauge instrument has been successfully made using the Arduino Uno-based BMP280 sensor. This instrument was standardized by using a standard measuring instrument at the Central Bureau of Meteorology, Climatology and Geophysics (BMKG) Region III Tuban Bali. It was obtained that the calibration equation is y = 1.0022x - 1.8907 with a coefficient of determination (R2) of 0.99998. This shows that the instrument made has a high degree of accuracy and precision.

Abstract

The measurement of heart rate and body temperature are two of the five Vital Signs that indicate human health. During this time the heart rate is measured using a stethoscope or counting the heart rate through the wrist but this can cause a Human Error. So a tool is designed that can measure heart rate and body temperature using pulse sensor and IR MLX90614 besed on ATmega328 which results can be displayed through the website with patients having their own ID so that the data is not mixed with other patient data and equipped with a database so that it can store patient data. From the results of trials on 3 subjects classified according to the age of 5, 9 and 23 years. The average accuracy of heart rate and body temperature measurements between the design tools and standard equipment is 98.54% for heart rate and 95.97% for body temperature.

Abstract

Chili is one type of vegetable that has many benefits and is favored in Indonesia and aboard. The benefits of chili are used as a kitchen spice and are used in the health sector as a mixture of herbal medicines and even as anti-cancer. Based on data from the Ministry of Agriculture of the Republic of Indonesia, chili productivity per plant is still relatively low (0.20-0.33 kg/tree or 6.84 tons/ha, so there needs an effort for improvement of productivity. Increased chili productivity can be done by plant breeding. In this study has been carried out Co-60 gamma radiation in plant breeding of chili (Capsicum annuum L.) by physical mutagen method. The chili used is red chili (hot chili F1). The purpose of this study is to find out the right Co-60 radiation dose for chili plant breeding. The gamma radiation dose used is 0 Gy as a control, 50, 75, 100, 125 and 150 Gy. The results showed that the right radiation dose for chili plant breeding was 75 Gy.

Abstract

Greenhouses play a crucial role in manipulating environmental conditions for optimal plant growth. While existing greenhouses enhance control over environmental factors, manual controls such as watering and humidity regulation often lead to suboptimal production and increased costs. This study proposes the development of a smart greenhouse with an automatic control system using fuzzy logic, specifically fuzzy Sugeno, to regulate watering and lighting based on soil moisture, temperature, and light intensity. The system's architecture involves sensor inputs, microcontroller processing, and the activation of actuators, such as UV lights and water pumps. Fuzzy logic is applied to interpret soil moisture and temperature inputs and determine optimal irrigation durations. The system's functionality is tested and validated through functional testing, Blynk application testing, and fuzzy Sugeno testing. Results indicate the successful implementation of the proposed smart greenhouse system. Functional testing demonstrates accurate sensor readings, including temperature and soil moisture. The Blynk application enables real-time monitoring and control of environmental conditions. Fuzzy Sugeno testing validates the irrigation control system, with an average error rate of 1.3%, affirming the system's alignment with desired specifications. Plant testing in different conditions showcases the effectiveness of the smart greenhouse in supporting plant growth and development.
