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.

Judul: Analisis Kinerja Support Vector Machine (SVM) Dan Probabilistic Neural Network (PNN) Pada Sistem Identifikasi Tumbuhan Obat Dan Tanaman Hias Berbasis Citra
Abstrak: This research analyzed perfomance of clasification for plant identification using Support Vector Machine (SVM) and Probabilistic Neural Network (PNN). In this research we used kernel linear, polynomial and RBF for clasifier SVM. In thus research, we use 1.440 medicinal plant images and 300 house plant images belong to 30 are extracted using Fuzzy Local Binary Patern based on texture feature.The expermental result shows that SVM kernel polynomial is superior compare to PNN with accuracy 73.57% to medicinal plant identification and SVM kernel RBF is superior compare to PNN with accuracy 81.11% to house plant identification. The proposed system is promising to improve identification medicinal plant and house plant.

Judul: Stress, Social Support, and Subjective Well-Being of Single Father Families During The Covid-19 Pandemic
Abstrak: Ayah tunggal kadangkala merasakan stres sehingga memerlukan dukungan sosial. Stres dan dukungan sosial akan memengaruhi kesejahteraan subjektif. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik keluarga, stres, dan dukungan sosial terhadap kesejahteraan subjektif 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 lebih dari separuh ayah tunggal kadang-kadang merasa gelisah, stres, ataupun kesal dalam rentang waktu sebulan terakhir. Lebih dari separuh ayah tunggal memiliki dukungan sosial rendah, sedangkan sebagian besar ayah tunggal memiliki kesejahteraan subjektif sedang. Uji korelasi menunjukkan bahwa terdapat hubungan negatif signifikan antara pendapatan per kapita dengan stres dan stres dengan kesejahteraan subjektif, sedangkan pendapatan per kapita dan dukungan sosial berhubungan positif signifikan dengan kesejahteraan subjektif. Uji regresi menunjukkan bahwa pendapatan per kapita dan dukungan sosial berpengaruh positif signifikan terhadap kesejahteraan subjektif, sedangkan stres berpengaruh negatif signifikan terhadap kesejahteraan subjektif., Single fathers sometimes feel stressed and need social support. Stress and social support will affect subjective well-being. This study aims to analyze the influence of family characteristics, stress, and social support on subjective wellbeing of single father families during the Covid-19 pandemic. The research used quantitative research method with cross sectional study design involving 60 single fathers selected by purposive sampling. The results found that more than most single fathers sometimes felt nervous, stressed, or annoyed in the past month. More than most single fathers have a low social support, while most single fathers have a moderate subjective well-being. Correlation test shows that there is a significant negative relationship between per capita income with stress and stress with subjective well-being, while per capita income and social support has a significant positive relationship with subjective well-being. Regression tests show that per capita income and social support has a significant positive effect on subjective wellbeing, while stress has a significant negative effect on subjective well-being.
