Implementasi metode convolutional neural network untuk klasifikasi tanaman pada citra resolusi tinggi

Abstract: Citra resolusi tinggi dari teknologi UAV (Unmanned Aerial Vehicle) dapat memberikan hasil yang baik dalam ekstraksi informasi sehingga dapat digunakan untuk monitoring dan updating data suatu wilayah. Pengambilan informasi dari citra dengan interpretasi visual sangat bergantung pada interpreter. Kendala utama interpretasi secara manual adalah saat melakukan pengenalan objek secara visual, khususnya pada objek tanaman pertanian. Kesalahan hasil asumsi interpreter dapat terjadi ketika citra yang diekstraksi memiliki objek yang kompleks dan memiliki karakter fisik yang hampir mirip apabila dilihat dari foto udara yang hanya memiliki band RGB (Red, Green, dan Blue). Penelitian ini mencoba mengimplementasikan pendekatan klasifikasi semantik secara otomatis yang dapat membedakan jenis tanaman sebagai alternatif pengenalan objek berdasarkan metode deep learning menggunakan Convolutional Neural Network (CNN). Metode CNN merupakan salah satu metode deep learning yang mampu melakukan proses pembelajaran mandiri untuk pengenalan objek, ekstraksi objek dan klasifikasi serta dapat diterapkan pada citra resolusi tinggi yang memiliki model distribusi nonparametrik. Pada penelitian ini, diterapkan algoritma CNN untuk membedakan jenis tanaman dengan memberikan label semantik dari objek jenis tanaman. Penelitian menggunakan 5 kelas jenis tanaman, yaitu kelas tanaman padi, bawang merah, kelapa, pisang, dan cabai. Proses learning jaringan menghasilkan akurasi 100% terhadap data training. Pengujian terhadap data validasi menghasilkan akurasi 93% dan akurasi terhadap data tes 82%. Hasil penelitian ini menunjukkan bahwa penggunaan metode CNN berpotensi untuk pendekatan pengenalan objek secara otomatis dalam membedakan jenis tanaman sebagai bahan pertimbangan interpreter dalam menentukan objek pada citra.

Somatotypes of young male athletes and non-athlete students in Yogyakarta, Indonesia

Abstract: There is a considerable corpus of evidence indicating that athletes succeeding in certain sports have distinctive body shapes that differ according to the demands of the type of sports and competitive level The aim of this study was to determine the specific morphological characteristics of young male athletes compared with non-athlete students in Indonesia Anthropometric measurements of 19 badminton players, 96 soccer players, 74 volleyball players, and 51 non-athlete undergraduate students, aged 16 to 28, were obtained in 1994 and 1995 Stature, body weight, bicondylar breadths of the humerus and femur, calf and upper arm circumferences, and skinfolds (at triceps, subscapula, calf, and supraspine) were measured for each subject Heath-Carter somatotypes were determined in all the subjects The results of the ANOVA of the body measurements showed that the three groups of athletes and the non-athlete students were heterogeneous: the badminton players were shorter and lighter with greater skinfold values among the athlete groups; the soccer players were relatively shorter and with smaller skinfold values and greater arm and leg girths; and the volleyball players were taller and heavier with smaller elbow and knee breadths and very small skinfold values The non-athlete students were characterized by greater arm girth, elbow breadths, knee breadths, and back and leg skinfolds In mean somatotype category, the badminton players were ‘central’ (33-37-37), the soccer players were ‘balanced mesomorph’ (27-49-30), the volleyball players were ‘mesomorph-ectomorph’ (24-35-37), and the non-athlete students were ‘ectomorphic mesomorph’ (27-52-38) Comparisons of international scope with each of the different sports showed that the Indonesian players were extremely short and light

Enhancing the quality of life for palliative care cancer patients in Indonesia through family caregivers: a pilot study of basic skills training

Abstract: Palliative care in Indonesia is problematic because of cultural and socio-economic factors. Family in Indonesia is an integral part of caregiving process in inpatient and outpatient settings. However, most families are not adequately prepared to deliver basic care for their sick family member. This research is a pilot project aiming to evaluate how basic skills training (BST) given to family caregivers could enhance the quality of life (QoL) of palliative care cancer patients in Indonesia. The study is a prospective quantitative with pre and post-test design. Thirty family caregivers of cancer patients were trained in basic skills including showering, washing hair, assisting for fecal and urinary elimination and oral care, as well as feeding at bedside. Patients’ QoL were measured at baseline and 4 weeks after training using EORTC QLQ C30. Hypothesis testing was done using related samples Wilcoxon Signed Rank. A paired t-test and one-way ANOVA were used to check in which subgroups was the intervention more significant. The intervention showed a significant change in patients’ global health status/QoL, emotional and social functioning, pain, fatigue, dyspnea, insomnia, appetite loss, constipation and financial hardship of the patients. Male patient’s had a significant effect on global health status (qol) (p = 0.030); female patients had a significant effect on dyspnea (p = 0.050) and constipation (p = 0.038). Younger patients had a significant effect in global health status/QoL (p = 0.002). Patients between 45 and 54 years old had significant effect on financial issue (p = 0.039). Caregivers between 45 and 54 years old had significant effect on patients’ dyspnea (p = 0.031). Basic skills training for family caregivers provided some changes in some aspects of QoL of palliative cancer patients. The intervention showed promises in maintaining the QoL of cancer patients considering socio-economic and cultural challenges in the provision of palliative care in Indonesia.

Primary treatment results of Nasopharyngeal Carcinoma (NPC) in Yogyakarta, Indonesia.

Abstract: Introduction Nasopharyngeal Carcinoma (NPC) is a major health problem in southern and eastern Asia. In Indonesia NPC is the most frequent cancer in the head and neck area. NPC is very sensitive to radiotherapy resulting in 3-year disease-free and overall survival of approximately 70% and 80%, respectively. Here we present routine treatment results in a prospective study on NPC in a top referral; university hospital in Indonesia.
