Germplasm conservation in the form of seed is convenient and most cost-effective ex situ conservation method for plant species producing orthodox seeds. Several species of plantation crops and spices produce non-orthodox seeds, which exhibit intermediate or recalcitrant seed storage behaviour. Storage of these species requires the use of in vitro conservation techniques for shortto medium-term ...

Crop damage by wildlife is a very prevalent form of human-wildlife conflict adjacent to protected areas, and great economic losses from crop raiding impede efforts to protect wildlife. Management plans are needed to decrease damage by raiding wildlife, yet conservation biologists typically lack the basic information needed for informed conservation strategies. Red-tailed monkeys (Cercopithecus ...

Cocoa plants are a leading plantation commodity that entirely exists in Indonesia. One of which is the highest production Edel 2019 located at PTPN XII Kendenglembu, has cocoa processing industry, namely Doesoen Kakao, and great potential improving economy social aspects. However, weakness using aluminum foil packaging, considered less environmentally friendly. The purpose this study to find ou...

Cocoa beans from several types of post harvest treatments were processed into cocoa butter, cocoa powder and chocolate spread using traditional processing techniques. OTA was analyzed in two hundred and sixteen (216) samples of cocoa and cocoa derived products using HPLC with fluorimetric detection. It was found that OTA content in cocoa nibs depended only on the state of cocoa pod and the time...
