Penelitian ini bertujuan untuk membuat aplikasi sederhana menggunakan GUI MATLAB untuk menganalisis spektrum biosensor berbasis Surface Plasmon Resonance (SPR). Metode yang dilakukan dalam pembuatan aplikasi dimulai dari tahap analisis, tahap desain interface, tahap coding dan tahap pengujian. Tombol Kurva simulasi pada menu editor berisi perintah untuk menampilkan spektrum SPR simulasi berdasarkan data indeks bias dan ketebalan yang dimasukkan dalam data input. Sedangkan Kurva Eksperimen berisi perintah untuk menampilkan titik â€“ titik hasil eksperimen. Akhirnya sensitifitas dari biosensor berbasis SPR dapat ditentukan nilainya dengan mengganti nilai â€“ nilai pada penel input data. Selain itu sistem SPR yang tidak diketahui nilai indeks bias dan ketebalannya dapat diprediksi nilainya dengan membandingkan kurva simulasi dan kurva eksperimen.

This research is an important step in energy planning which is the main in electricity planning in the long-term forecast for the demand and supply of energy supply. A simple model is presented using LEAP (Long Term Alternative Energy Planning System) as a broadcasting tool and Central Java as a case study case for this research. This research discusses future energy needs. Electricity needs in the household, industrial, business, and community sectors are calculated based on data on participation, electricity consumption, installed electricity generation capacity, electrification ratio, and electricity strengthening. The base year of this research is 2020 and 2045 is the final period of this forecast. The results of this study indicate that energy needs in Central Java will increase by an average of 23.44% in 2045 or five times compared to 2020 by taking into account various factors of regional economic growth and electricity demand each year

Insects in the form of mosquitoes are transmitting vectors of several types of diseases that are quite dangerous and need to be watched out for because they can be deadly, such as dengue fever mosquitoes, malaria, elephantiasis and the like. Patients suffering from mosquito-borne diseases must be treated immediately to find out the type of disease they are suffering from and their treatment solutions. The era of digitalization that is growing rapidly, including in the field of medical science, makes the use of information technology to help improve quality services for the community. The analysis used in this research is using the forward chaining method, as a comparison of the overall process of the problems obtained in the investigation and developed using the waterfall paradigm. Forward chaining is implemented because the disease diagnosis process begins by observing the symptoms experienced by a patient and then continues with a tracing process that results in conclusions about the dengue fever suffered. While the waterfall method is used in the development of this expert system because the method can accommodate all stages of the system starting from the analysis of functional and non-functional system requirements, system design, coding, expert system testing and the last stage is expert system maintenance. The data used in this study used data from patients infected with mosquito bites at the Maos Health Center, Cilacap Regency in 2021. Testing is carried out using the black box testing method where the expert system is tested on end-users to determine the level of success and usability of the developed system. The questionnaire was given to 76 respondents with the results of the questionnaire: 91.9% indicating the level of user satisfaction, 89.6% indicating the level of effectiveness and 92.2% indicating the level of efficiency of the expert system. The output of this study is the conclusion of the disease suffered by the patient and the solution for handling it.
