Judul: Perbandingan Classifier untuk Identifikasi Citra Tanaman Hias
Abstrak: The use of an appropriate classification technique significantly determines the result of the identification process. In this research, we perform comparison of classification techniques for the identification of ornamental plants. The classification techniques used are Probabilistic Neural Network (PNN), K-Nearest Neighbor (KNN), Naive Bayes (NB) and the combination of K- Nearest Neighbor and Naive Bayes. We use 300 images of ornamental plants, consisting of 30 different types of plants. Plant image features are extracted using texture extraction technique, called Local Binary Pattern (LBP). The best performance was shown by the classification technique using PNN, KNN, and the combination of KNN and NB, with an accuracy of 72.22%. This result provides a promising prospect for an effective and efficient ornamental plants identification system.

Abstrak: Identification house plant species automatically still be a problem for recognizing various kind of house plants. This research proposes a new method for identifying a house plant using Local Binary Patterns (LBP) descriptor and Probabilistic Neural Network (PNN). There are three kinds of LBP descriptor used in this research, i.e. , , and . Database of 300 house plant images belong to 30 different types of house plant in Indonesia are extracted using , , and based on texture feature and classified using PNN. The experimental result shows that has the best accuracy to indentify house plants with accuracy 73.33%. The proposed system is promising since it is capable to identify house plants species efficienty and accurately

Judul: Economic Pressures, Coping Strategies, and  Quality of Life of Single Father Families during The Covid-19 Pandemic.
Abstrak: Keluarga ayah tunggal rentan dengan permasalahan ekonomi di masa pandemi Covid-19. Strategi koping dibutuhkan sebagai upaya untuk meningkatkan kualitas hidupnya. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik keluarga, tekanan ekonomi, dan strategi koping terhadap kualitas hidup pada keluarga ayah tunggal selama pandemi Covid-19. Penelitian ini menggunakan metode penelitian kuantitatif dengan desain cross sectional study yang melibatkan 60 ayah tunggal yang dipilih secara purposive sampling. Hasil penelitian menemukan bahwa hampir dari separuh ayah tunggal memiliki tekanan ekonomi objektif dan subjektif sedang, sebagian besar ayah tunggal memiliki strategi koping rendah, sedangkan hampir separuh ayah tunggal memiliki kualitas hidup sedang. Uji korelasi menunjukkan bahwa tekanan ekonomi objektif dan subjektif berhubungan negatif dengan kualitas hidup, sedangkan pendapatan per kapita dan strategi koping berhubungan positif dengan kualitas hidup. Uji regresi menunjukkan bahwa tekanan ekonomi subjektif berpengaruh negatif terhadap kualitas hidup, sedangkan strategi koping berpengaruh positif terhadap kualitas hidup., Single father families are vulnerable to economic problems during the Covid 19 pandemic. Coping strategies are needed to improve their quality of life. This study aims to analyze the influence of family characteristics, economic pressures, and coping strategies on the quality of life of single father families during the Covid-19 pandemic. The research used a quantitative research method with a cross-sectional study design involving 60 single fathers selected by purposive sampling. The results found that almost half of single fathers had moderate economic pressures, almost all single fathers had low coping strategies, and almost half of single fathers had moderate quality of life. Correlation test showed that objective and subjective economic pressures are negatively related to the quality of life, while per capita income and coping strategies are positively related to quality of life. Regression test showed that subjective economic pressure had a negative effect on the quality of life while coping strategies had a positive effect on the quality of life.
