Extractive Software Product Line Engineering (SPLE) puts features on the foremost aspect in domain analysis that needs to be extracted from the existing system's artifact. Feature in SPLE, which is closely related to system functionality, has been previously studied to be extracted from source code, models, and various text documents that exist along the software development process. Source code, with its concise and normative standard, has become the most focus target for feature extraction source on many kinds of research. However, in the software engineering principle, the Software Requirements Specification (SRS) document is the basis or main reference for system functionality conformance. Meanwhile, previous researches of feature extraction from text document are conducted on a list of functional requirement sentences that have been previously prepared, not literally SRS as a whole document. So, this research proposes direct processing on the SRS document that uses requirement boilerplates for requirement sentence statement. The proposed method uses Natural Language Processing (NLP) approach on the SRS document. Sequence Part-of-Speech (POS) tagging technique is used for automatic requirement sentence identification and extraction. The features are acquired afterward from extracted requirement sentences automatically using the word dependency parsing technique. Besides, mostly the previous researches about feature extraction were using non-public available SRS document that remains classified or not accessible, so this work uses selected SRS from publicly available SRS dataset to add reproducible research value. This research proves that requirement sentence extraction directly from the SRS document is viable with precision value from 64% to 100% and recall value from 64% to 89%. While features extraction from extracted requirement sentences has success rate from 65% to 88%.

A common risk of death is caused by heart disease. It is critical in the field of medicine to be able to diagnose cardiac disease in order to adequately prevent and treat patients. The most accurate method of prediction has the potential to both extend the patient's life and reduce the severity of their cardiac disease. The use of machine learning is one approach that may be taken to generate predictions. In this study, patient medical record information was used in conjunction with an algorithm for logistic regression in order to make heart disease diagnoses. The outcomes of the logistic regression have been utilized to achieve a high level of accuracy in the prediction of heart disease. To get the model coefficients needed for the equation, the experiment uses an iterative form of the logistic regression test. Iteration 14 produced the best results, with an accuracy of 81.3495% and an average calculation time of 0.020 seconds. The best iteration was reached at that point. The percentage of space that lies beneath the ROC curve is 89.36%. The findings of this study have significant implications for the field of heart disease prediction and can contribute to improved patient care and outcomes. Accurate predictions obtained through logistic regression can guide healthcare professionals in identifying individuals at risk and implementing preventive measures or tailored treatment plans. The computational efficiency of the model further enhances its applicability in real-time decision support systems.

Pengelolaan keuangan pada koperasi secara manual akan menyulitkan dalam pembuatan laporan keuangan yang representatif secara tepat waktu. Selain karena kurangnya pemahaman SDM yang ada terhadap sistem akuntansi, pengarsipan dan pembukuan transaksi secara manual memerlukan waktu yang lama dalam inventarisasi atau rekap transaksi. Pemanfaatan teknologi informasi berupa perangkat lunak akuntansi dibutuhkan untuk memasukkan data setiap transaksi agar tersimpan secara digital sehingga dapat dilakukan pemrosesan secara otomatis dalam pembuatan laporan keuangan yang sesuai dengan prinsip akuntansi. Namun, implementasi perangkat lunak akuntansi harus  diiringi dengan Standard Operating Procedure (SOP) yang sesuai dan jelas agar dalam operasional dan input transaksi bisa sesuai dan laporan yang dihasilkan sesuai dengan yang diharapkan. Oleh karena itu, proses diskusi untuk penggalian permasalahan transaksi dan pembuatan panduan operasional yang tepat perlu untuk disusun dan di-training-kan ke pengurus dan pengelola koperasi. Kegiatan ini diharapkan dapat meningkatkan SDM dari lembaga mitra kegiatan dalam hal pembuatan laporan keuangan secara akurat dan efisien dengan memanfaatkan teknologi informasi yang sudah terstandardisasi dengan prinsip akuntansi untuk entitas tanpa akuntabilitas publik (SAK-ETAP) yang menjadi dasar dalam penyusunan laporan koperasi. Berdasarkan hasil survey pasca kegiatan, 80% peserta menyatakan bahwa modul standar prosedur operasional atau SOP bagi SDM koperasi yang disusun sangat membantu dalam menjalankan aktivitas hariannya, terutama dalam melakukan input data transaksi ke dalam sistem. Selanjutnya proses pengawasan atau pendampingan secara berkala tetap diperlukan guna menjaga agar system tetap dijalankan dengan baik sesuai dengan SOP yang ada.

Stunting or cases of failure to thrive in toddlers is one of the most serious health problems faced by the people of Indonesia. Based on data from the Ministry of Health and the Central Statistics Agency, East Java Province has a stunting prevalence value of 26.8% which is categorized as a high prevalence value according to the standards of the World Health Organization (WHO). Random forest is one of the machine learning algorithms in the field of artificial intelligence that can learn patterns from labeled data so that it can be used as a method for predicting or forecasting data. This approach is considered very suitable to be used in predicting the value of stunting prevalence because stunting prevalence data is usually accompanied by other data in the health sector according to survey results. Previous studies on the prediction of stunting prevalence used secondary data sourced from one survey only. Therefore, this study is one of the efforts to contribute in providing solutions for the stunting problem in East Java Province by combining several data from different surveys in the same year. The results of this study show that from 20 factor candidates for predicting stunting prevalence value, only 12 factors are suspected to be causative factors based on their correlation value. However, the prediction results obtained using the random forest algorithm in this study, with data consisting of 12 features and a dataset consisting of only 38 data, have results with error values of 1.02 in MAE and 1.64 in MSE that are not better than multi-linear regression which can produce smaller error values of 0.93 in MAE and 1.34 in MSE.
