MORPHOLOGICAL AND MOLECULAR IDENTIFICATION OF HELOPELTIS SPECIES ON COCOA FROM KALIWINING EXPERIMENTAL STATION, JEMBER, INDONESIA

Morphological and Molecular Identification of Helopeltis Species on Cocoa from Kaliwining Experimental Station, Jember, Indonesia

Severe crop loss of cocoa in Indonesia has long been reported to be caused by Helopeltis.It has been noted that cocoa and Helopeltis have existed in Kaliwining Experimental Station of Indonesian Coffee and Cocoa Research Institute (ICCRI), Jember, Indonesia, for about 100 years, and the species have developed during that time.Our study aimed for ex

Optimal Gliding Trajectories for Descent on Mars

In this paper, optimal gliding trajectories are analyzed, formulating an optimal control problem to be solved computationally via nonlinear programming.A multi-objective terminal cost function that minimizes the velocity, altitude, horizontal flight path angle, and the error of a desired terminal point is formulated.The results are validated via Mo
