(2012)Bekasam is an Indonesian fermented fish product that has sour taste and mostly contain lactic acid bacteria (LAB). This study aimed to obtain and characterize LAB isolates from bekasam and to study their potency in inhibiting ... -
Pemodelan data kesehatan Kabupaten Banyuwangi dengan regresi terboboti geografis
(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 ... -
Development of robustness on additive Main Effect – Multiplicative Interaction (AMMI) Models
(2012)AMMI model for interactions in two-way table provide the major mean for studying stability and adaptability through GEI, which modeled by full interaction model. Eligibility of AMMI model depends on the assumption of ... -
Simulation model application to predict impact of climate change on potato productivity in Indonesia
(2012)Potato is an important horticulture crop in Indonesia in terms of planted area more than 55.000 ha and its production 864.000 ton. The crop is commonly grown in upland areas above 800 m where runoff and erosion often cause ... -
The potency of agarolytic bacteria as producer of exogenous agarase enzyme to improve growth of abalone juvenile (Haliotis asinina Linn. 1758)
(2012)There is a great potential of using probiotics in aquaculture to increase growth rates and improve nutritional status of cultured animals. The aims of this research were to isolate and select agarolytic bacteria, to identify ... -
Isolation and characterization of an aluminum tolerance gene in Rice
(2011)Aluminum (Al) toxicity is the major limiting factor of crop production in acid soil. Aluminum tolerance in rice is considered as a quantitative trait controlled by many genes. The objectives of this research were to isolate, ... -
Genetic transformation of rice using rhizobium and agrobacterium and functional analysis of OsHox6 Gene
(2012)Rice (Oryza sativa) is not only the most important crop in the world, but also a model plant for functional genomic studies. Genetic transformation is a routine technique for transferring important traits into plants ... -
Genetic diversity and microevolution of pyricularia grisea from grasses
(2012)Pyricularia is the fungus caused rice and grasses blast disease. They are morphologically indistinguishable, therefore their specific epithet is often based on host. The concept of Pyricularia species using nucleotide ... -
Isolation, cloning, and expression analysis of gene coding copper/zinc superoxide dismutase (CuZn-SOD) from Melastoma malabathricum L.
(2012)Melastoma malabathricum L. is an indigenous plant in tropical Southeast Asia with exceeding tolerance to aluminum (Al) stress in acid soils. Although increasing evidence suggests that Al-stress is accompanied by oxidative ... -
