Abstract

South Lamaknen District is the center of coffee production in Belu Regency. Coffee production is influenced by external and internal factors, H. vastatrix attacks are among the main external factors that limit coffee production in this district. Data information related to leaf rust disease in Belu district does not yet exist. Data on the distribution and severity of coffee leaf rust disease in this district do not yet exist. Such data is needed to determine appropriate control strategies to improve coffee production. The study aimed to obtain data on the severity of coffee leaf rust disease in smallholder coffee plantations in Belu Regency. The research method used was purposive random sampling (PRS) in the Belu people's coffee center in Lakmaras and Henes Villages, South Lamaknen District, with a geographical location between 9 ْ0.9' 26.61"N and 125 ْ 09' 50" LS, at an altitude between 866,7 – 1007,7 m above sea level. This study shows that coffee leaf rust disease is spread in geographical locations 9 ْ 0.9' 26.61"N and 125 ْ 09' 50" LS. The highest intensity of coffee leaf rust disease occurred in Henes village, which was 39%, while Lakmaras village was 22%. External factors affecting the incidence and severity of disease are temperature and use distance between coffee plants.

Abstract

This study aims to determine the effect of soaking duration of shallot bulbs using Local Microorganisms (MOL) on seed viability and vigor during the early growth phase. The research was conducted at the Agrotechnology Laboratory, Unit Stiper Petra Baliem Wamena, from April to August 2018 using a Completely Randomized Block Design (CRBD) with six MOL soaking duration treatments: 0 minutes (control), 30 minutes, 60 minutes, 90 minutes, 120 minutes, and 150 minutes, each repeated four times. The observed parameters included germination percentage, maximum growth potential, growth rate, plant height, and number of leaves at 14 days after planting (DAP). The results showed that MOL soaking treatments influenced the viability and vigor of shallot seeds. The highest germination percentage was obtained at the 60-minute treatment (95%), while maximum growth potential was relatively uniform across almost all treatments (100%). The highest growth rate was observed at the 150-minute soaking duration (85.57%), whereas the control treatment produced the lowest value (57.23%). Early vegetative growth also showed the best response at the 60-minute treatment, with plant height reaching 7.50 cm and the number of leaves reaching 10.75 at 14 DAPS.
