(2012)Analisis regresi adalah metode yang digunakan untuk menganalisis data dan mengambil kesimpulan tentang hubungan ketergantungan antara peubah respon dengan peubah penjelas, namun pemodelan dengan menggunakan analisis regresi ... -
Development of climate index insurance model for improving rice farmers resilience to cope with climate change
(2012)Agriculture, particularly the rice farming system (SUT) is very vulnerable to weather and climate related shocks. Crop failure due to these events will be amplified by climate change. As rice is main staple food in Indonesia, ... -
Bayesian models for small area estimation based on unequal probability sampling of binomial and multinomial responses
(2012)In this research a Bayesian Method of Small Area Estimation (SAE) has been developed based on binomial and multinomial response variables using Susenas data obtained from unequal probability sampling. Case study was carried ... -
Climate risk management based on operating farming systems for rice through the use of dynamic cropping pattern
(2012)El-Nino events can lead to decreased production of rice, due to the addition of the planting area is experiencing drought and loss yield. Early withdrawal of the rainy season could lead to the resignation of a second crop. ... -
The life strategy of Arfak Tribe based on craniofacial shape, growth rate, and sexual maturation
(2012)Arfak tribe is one of traditional tribes living in Manokwari, West Papua Province. The tribe has an unique natural life differently with other tribes in Indonesia. The nature of a life cycle is a result of an adaptive ... -
