Abstract

Desa Sundawenang di Kabupaten Sukabumi, Jawa Barat, merupakan desa yang memiliki banyak potensi, antara lain posisi yang strategis di jalan raya Sukabumi-Bogor, produksi singkong, dan terdapat sejumlah industri seperti pabrik otomotif, elektronik, boneka, wig, dan sebagainya. Kondisi desa tersebut mengundang sejumlah besar pendatang, sehingga diperkirakan 40% penduduk desa bukanlah penduduk asli setempat. Tersebarnya sejumlah industri di wilayah Desa Sundawenang juga berpengaruh terhadap mata pencaharian warga. Tercatat sebanyak 41% warga berprofesi sebagai karyawan, kemudian disusul dengan wiraswasta dan jasa (28%), petani (27%), dan PNS (4%). Dengan karakteristik tersebut, Kepala Desa Sundawenang yang baru menjabat pertama kali memerlukan data dan berbagai laporan untuk menyusun berbagai program dan kebijakan desa yang sesuai. Village resource management system (VRMS) dibangun untuk memberikan solusi bagi kebutuhan Kepala Desa tersebut. VRMS terdiri dari tiga aplikasi utama, yaitu aplikasi pelayanan desa, aplikasi pengelolaan data desa, dan aplikasi analisis data. Aplikasi pelayanan desa telah diresmikan dan diberikan pelatihan penggunaannya kepada aparat Desa Sundawenang. Diharapkan aplikasi ini dapat diterapkan pada desa-desa lain di Indonesia dengan penyesuaian yang dapat dilakukan untuk mengakomodasi kebutuhan yg lebih khusus.

Abstract

Information modeling a very important role in the development of information systems today. Information modeling is an activity to create a conceptual model that includes all significant information in business processes. Using information modeling, a machine is needed for implementation, and redundancy and anomaly problems are also common in databases. This problem arises when the database is not normalized. To solve the problem, this research will analyze the SME information system using the Fully Communication Oriented Information Modeling  (FCO-IM) method and compare it with the method without FCO-IM made by 12 designers. The results of the analysis, information modeling using FCO-IM method can produce a relational data schema that already meets 3NF normalization and is suitable for implementation in SME information system development so that it can be used as an option in data modeling and can avoid data redundancy problems.

Abstract

Employee attrition is the loss of employees in a company caused by several factors, namely employees resigning, retiring, or other factors. Employee attrition of employees can have a negative impact on a company if it is not handled properly, including decreased productivity. The company also requires more time and effort to recruit and train new employees to fill vacant positions. This attrition prediction aims to help the human resources (HR) department in the company to find out what factors influence the occurrence of employee attrition. This research implements Random Forest while comparing Information Gain, Select K Best, and Recursive Feature Elimination feature selection methods to find which feature selection produces the best performance. The implementation of the aforementioned methods outperforms previous research in terms of accuracy, precision, recall, and f1 scores. In preparing this research, the first author collects data sets, makes programs, and compiles journals. The second author assists the first author in programming and preparing the journal. From the results of the tests that have been carried out, Information Gain produces the highest accuracy value of 89.2%, while Select K Best produces an accuracy value of 87.8% and Recursive Feature Elimination produces an accuracy value of 88.8%.

Abstract

Work readiness for college graduates is an essential and significant thing to get a job immediately after graduation. But what happens is that many graduates are unemployed after graduation or do not get jobs that match the majors they have studied for more than four years. Therefore, by using a people analytics approach, this study aims to predict the work readiness of Telkom University students and find out what factors affect student work-readiness after graduation. The model built is a multi-classes classification model. This model uses Chi-square Test calculation for feature selection, Multinomial Logistic Regression and Random Forest as a classification method, and confusion matrix as an evaluation method. Multinomial Logistic Regression is used because several studies use this algorithm for categorical data, while Random Forest is used to compare which model produces better accuracy. This study conducted several test scenarios, which obtained the best model by performing hyperparameter tuning and handling unbalanced data with SMOTE-ENN. Handling imbalanced data with SMOTE-ENN is used to improve accuracy scores and predict classes well, especially for minority class. The best accuracy of the Multinomial Logistic Regression method is 53.9%, and Random Forest is 48.5%.

Abstract

Tracer analysis is one of the ways to increase a university's accreditation. Tracer studies, also known as graduate surveys, are beneficial for enhancing learning and developing university curricula. The period it takes graduates to secure employment is a measure of their quality. The sooner graduates obtain a job, the higher their perceived quality. Conversely, if it takes graduates longer to find employment, their quality is deemed lower. To gain new knowledge from the tracer study dataset regarding the relationship between university contribution and alumni capability in the job market, in this study, data mining techniques are used to determine what factors influence the length of time it takes college graduates to find employment. This classification model contains a total of 2288 data instances from the categorical type of dataset. The features are selected using chi-square. Two classification algorithms, Decision Tree and Support Vector Machine, are compared for the best model. This study also used hyperparameter tuning to improve accuracy. The results show decision tree produces higher accuracy compared to the support vector machine. The accuracy obtained from the decision tree model is 55.02% and increased to 65.06% after hyperparameter tuning. Meanwhile, the support vector machine brought an accuracy of 60.40% and increased to 62.15% after hyperparameter tuning. Factors that affect the classification of the alumni waiting period in getting a job in this study are sex, faculty of the study field, department of the study field, study period, company specification, company category, and work location.

Abstract

Every Muslim in the world believes that the Quran is a miracle and the words of God (Kalamullah) revealed to the Prophet Muhammad SAW to be conveyed to humans. The Quran is used by humans as a guide in dealing with all problems in every aspect of life. To study the Quran, it is necessary to know what topic is being discussed in every single verse. With the help of technology, the verses of the Quran can be given topics automatically. This task is called multilabel classification where input data can be classified into one or more categories. This research aims to apply the multilabel classification to classify the topics of the Quranic verses in English translation into 10 topics using the Word Centrality measurement as the word weighting value. Then a comparison is made to the 4 classification methods, namely SVM, Naïve Bayes, KNN, and Decision Tree. The result of the centrality measurement shows that the word ‘Allah’ is the most important or the most central word of the whole document of the Quran with the scenario using stopword removal. Furthermore, the use of word centrality value as term weighting in feature extraction can improve the performance of the classification system.

Abstract

Pemilihan kepala daerah (pilkada) merupakan pemilihan umum untuk memilih gubernur dan wakil gubernur yang dilakukan oleh masyarakat setempat yang memenuhi syarat sebagai pemilih. Gubernur merupakan pemimpin daerah yang bertugas dalam memimpin suatu wilayah daerah provinsi di Indonesia. Dalam hal ini bakal calon gubernur membutuhkan sentimen dari masyarakat sebagai sumber informasi untuk mengetahui citra bakal calon gubernur. Sentimen yang didapatkan dari masyarakat tidak hanya bersifat positif, melainkan juga bersifat negatif dan netral. Sentimen yang digunakan pada penelitian ini adalah tweet dari masyarakat yang dicrawling dari twitter dan berhubungan dengan bakal calon gubernur Jawa Barat 2018. Pada penelitian tugas akhir ini penulis membangun sistem klasifikasi sentimen masyarakat dengan metode Naive Bayes Clasifier (NBC). Model Naive Bayes Clasifier (NBC) digunakan untuk mendapatkan nilai prefrence value dari masyarakat terhadap kandidat calon gubernur Jawa Barat 2018. Hasil pengujian dengan metode evaluasi menghasilkan rata-rata akurasi sebesar 76,56%. Untuk hasil pengujian respon positif masyarakat di twitter yang terbesar diproleh oleh Deddy Mizwar dengan nilai prefrence value sebesar 34,3%. Dengan demikian, klasifikasi sentimen menggunakan NBC dapat digunakan untuk mengukur prefrence value pada kasus pemilihan kepala daerah.
