Abstract

UIN Walisongo's student identity card (KTM) does not have much function other than just for student identification. Even if the function is increased, it can be used for absenteeism at lectures, borrowing books, or double as an automated teller card (ATM). Doing absences using KTM requires a feature matching method for matching the intended KTM image with the KTM that is searched for in the student database. The feature matching process is based on feature detection in images using various methods such as ORB and Scale Invariant Feature Transform (SIFT). We can perform the feature matching method using the Brute-Force method and the Fast Library Approximated Nearest Neighbor (FLANN) on Google Colab with Python. The results of feature matching on the FLANN method are more than the Brute-Force method. The validation of the two image feature matching was carried out using the Root Mean Square Error (RMSE) method, resulting in an average value of 10.424. The purpose of this article is to detect student ID cards with matching features in the image. The FLANN and Brute-Force feature matching methods can be used to detect KTM UIN in images. Keywords: feature matching, SIFT, FLANN, Brute-Force, RMSE

Abstract

Angkatan kerja adalah mereka yang memiliki pekerjaan, atau sedang bekerja atau menganggur sementara karena beberapa alasan. Pertumbuhan angkatan kerja dipengaruhi oleh jumlah penduduk dan struktur demografi penduduk salah satunya tingkat pendidikan. Biplot adalah salah satu analisis dalam analisis multivariat untuk menggambarkan baris dan kolom yang terdapat dalam matriks serta menggambarkan hubungan antara objek dan variabel dalam grafik tunggal. Pada penelitian ini akan dilakukan analisis biplot pada data dari BPS yaitu penduduk berumur 15 tahun ke atas yang bekerja menurut lapangan pekerjaan utama yang terdiri 17 sektor dan pendidikan tertinggi yang ditamatkan per Februari 2022. Dari analisis yang telah dilakukan, dapat diketahui bahwa vektor peubah SLTP memiliki nilai keragaman paling besar dan vektor peubah universitas memiliki nilai keragaman paling kecil. Kemudian hubungan antara amatan berupa lapangan pekerjaan dan vektor peubah berupa tingkat pendidikan dapat dikelompokkan menjadi dua kelompok yang masing-masing kelompok terdiri dari pembagian 17 sektor lapangan kerja

Abstract

The increase in air pollution that occurs due to industrial and economic activities will affect the rainwater content. The vital function of one of the sources of clean, namely rainwater, makes the urgency of research on indications of a decrease in rainwater quality by analyzing the substances contained. The parameters used for the determination of rainwater quality are the degree of acidity, conductivity, calcium, magnesium, sodium, potassium, ammonium, sulfate ions, nitrate ions, chloride ions, total hardness, and acidity. The data source used is data from the Central Statistics Agency (BPS) entitled "Indonesian Environmental Statistics 2022". By using the main component analysis method to reduce the variables of rainwater quality influence factors in 35 city/station samples in Indonesia, results were obtained, namely rainwater quality influence factors that can be formed into three main components with each containing 10 variables consisting of acidity, conductivity, magnesium, sodium, potassium, chloride ions, sulfate ions, nitrate ions, total hardness, and acidity capable of explaining 73.695% of the total variance.

Abstract

There are different characteristics of each entry route, so there will be the potential to achieve a different GPA. There are 3 types of entrance routes for public universities held by LTMPT, namely SNMPTN, SBMPTN, and SMMPTM. The achievement of student learning outcomes in tertiary institutions can be seen through the final results indicated by the GPA. Diploma and undergraduate program students have four graduation predicates, three of which are satisfactory (GPA 2.76-3.00), very satisfactory (GPA 3.01-3.50), and with honors (GPA more than 3.50). The population in this study were all PTN graduates from 2018 to 2022. The sample used in this study was at least 50 PTN graduates from 2018 to 2022 and 150 samples. This research will be tested using the Chi-Square test method. Based on the Chi-Square test on the contingency table related to the relationship between college admissions and student graduation predicates, it can be concluded that there is no relationship between college admissions and student graduation predicates. In addition, the relationship between university admissions and student graduation predicates is related to majors and campus clustering in 2020. Meanwhile, the relationship between university admissions and student graduation predicates has no relationship with gender and domicile.

Abstract

Lautan memiliki lebar yang sangat luas dibanding daratan yang ada di bumi kita. Tidak hanya daratan saja yang dihabitati oleh makhluk hidup, tetapi perairan juga. Peraian sendiri dibagi menjadi berbagai macam yaitu air tawar, air laut, dan air payau Banyaknya kelompok dan jenis ikan yang ada membuat kita harus mengelompokkannya berdasarkan kelompok untuk dapat membedakannya. Kelompok ikan didasarkan dengan berbagai macam kelompok seperti habitat, bentuk, anatomi, hingga ukurannya. Mengutip dari data yang didapatkan pada laman kaggle, terdapat jenis ikan yang memiliki bentuk hampir menyerupai satu sama lain. Jenis-jesnis ikan yang disebutkan dalam data yaitu ikan bream, ikan parkki, ikan pearch, ikan smelt, ikan whitefish, ikan pike, dan juga ikan roach. Dilakukanlah analisis diskriminan untuk mengklasifikasikan ikan yang belum dapat dibedakan karena bentuk fisiknya yang hampir menyerupai ke dalam gugus/kelompok yang sudah ditentukan supaya tidak terjadi kerugian dalam penjualan pasar ikan. Pada hasil analisis dengan uji Wilk’s Lambda didapatkan masing-masing jenis ikan memiliki perbedaan yang signifikan, lalu kelima fungsi diskriminan dapat secara nyata membedakan ketujuh kategori target kelompok.

Abstract

Technological advances in the field of financial innovation, namely e-wallets, provide convenience and practicality in making transactions online. The use of e-wallets is popular among students, one of which is the Faculty of Science and Technology, Airlangga University. Students with interests or tastes in the type of e-wallet and the running of all activities offline make it very likely that there will be a change in student interest from one e-wallet to another e-wallet. The change in interest will be analyzed with the Markov chain transition probability. The data in this study is primary data by conducting an online survey of 100 respondents in the form of a g-form given to students of the Faculty of Science and Technology, Airlangga University. Based on the results of the Markov chain transition opportunities, it can be concluded that the use of e-wallet applications can move according to the advantages of e-wallet applications in each region. This change in interest in e-wallet application users occurs because the application of choice is an application that provides easy access, lots of discounts, small admin fees, and others.
