Abstract

Text mining mengacu pada proses mengambil informasi berkualitas tinggi dari teks. Informasi berkualitas tinggi biasanya diperoleh melalui peramalan pola dan kecenderungan melalui sarana seperti pembelajaran pola statistik. Salah satu kegiatan penting dalam text mining adalah klasifikasi atau kategorisasi teks. Kategorisasi teks sendiri saat ini memiliki berbagai metode antara lain metode K-Nearest Neighbor, Naïve Bayes, dan Centroid Base Classifier, atau decision tree classification.Pada penelitian ini, klasifikasi keluhan mahasiswa dilakukan dengan metode centroid based classifier dan dengan fitur TF-IDF-ICF, Ada lima tahap yang dilakukan untuk mendapatkan hasil klasifikasi. Tahap pengambilan data keluhan kemudian dilanjutkan dengan tahap preprosesing yaitu mempersiapkan data yang tidak terstruktur sehingga siap digunakan untuk proses selanjutnya, kemudian dilanjutkan dengan proses pembagian data, data dibagi menjadi dua macam yaitu data latih dan data uji, tahap selanjutnya yaitu tahap pelatihan untuk menghasilkan model klasifikasi dan tahap terakhir adalah tahap pengujian yaitu menguji model klasifikasi yang telah dibuat pada tahap pelatihan terhadap data uji. Keluhan untuk pengujian akan diambilkan dari database aplikasi e-complaint Universitas Muhammadiyah Sidoarjo. Adapun hasil uji coba menunjukkan bahwa klasifikasi keluhan dengan algoritma centroid based classifier dan dengan fitur TF-IDF-ICF memiliki rata-rata akurasi yang cukup tinggi yaitu 79.5%. Nilai akurasi akan meningkat dengan meningkatnya data latih dan efesiensi sistem semakin menurun dengan meningkatnya data latih.

Abstract

One of methods that can be used to determine the stability of a power system if the fault occured is the equal area criterion method. The equal area criterion method (Equal Area Criterion, EAC) is an example of a direct method for predicting the stability and also the critical clearing time (Critical clearing time). However, to calculate the complex calculations required to determine the equivalent impedance of each condition system. In this study used several approaches to facilitate the calculation of the equivalent impedance. This method uses the equation of power losses. This method is equivalent impedance using modified with Ploss and Qloss for Determining Pmax. From the analysis, it can be concluded the use of this method is quite accurate in analyzing or calculating the transient stability of the generator system in South Sulawesi, with each loading condition, before, during and after short circuit. Generator being looked at is Bakaru, Pare, Suppa, Barru and Sengkang.

Abstract

In the 20th century this distance is still a constraint in efforts to measure and retrieve data. In an efficiency effort, a long distance measuring device is required. One method to measure from a distance is to use the Telemetry method. Telemetry is a method for measuring a variable in which monitoring is done remotely. The use of telemetry can be used to transmit data from the flowmeter sensor to be received by the receiver. This study discusses the effect of obstacles on transmitter work to send data to the receiver and test the accuracy of the flowmeter sensor. From this study it can be concluded that the effective distance of data transmission depends on the obstacle, the farthest distance is the moment without obstacles, then decreases when there is a hitch, and will decrease again when one receiver or transmitter is placed in a closed room. And for the accuracy of the sensor, the percentage of accuracy is low at the time of the slow water current, and vice versa high accuracy is obtained when the water current is fast. Based on the research we poured in this journal, water flow measurements using RF Arduino-based 433MHz Modules can measure the flow of water at a distance of up to 35meter with an average error of only 4.1%.

Abstract

Light is a propagation of electromagnetic waves that spread all directions that play an important role in everyday life because it is an absolute part of life and without the light of life on earth can not develop. The amount of light illuminance is necessary to know because basically humans require adequate lighting. The instrument for measuring light illuminance is a luxmeter or light meter. However, this gauge is difficult to obtain and the price of the tool is expensive so that it can only be found in certain school laboratories or colleges. While telemetry is the process of measuring the parameters of an object (objects, space, natural conditions) that the measurement results are transmitted to other places via data transmission without or using a cable (wireless). The purpose of this study is to measure, to know the conditions of light intensity. This research uses experimental model of light intensity measurement using independent measuring instrument with combination of LDR and Arduino uno consisting of transmitter and receiver. In the transmitter there are LDR, Arduino Uno, and RF Module Board 433 MHz components, while the receiver consists of Arduino Uno, laptop, and RF Module Board 433 MHz. In this design is also done a variety of testing tools using distance variables. Overall this tool is working well. The system has successfully delivered telemetry measurement results with a range of conditions without a wall barrier with a maximum distance of <28 m. And conditions there are obstacles diding with a maximum distance <13.2.
