Abstract

Selayar Islands Regency is one of the coconut (Cocos nucifera L.) producing centers in South Sulawesi. C. nucifera from this area is one type of coconut that fills the market spread across several areas in South Sulawesi. Coconut character as a determinant of consumer attractiveness. In addition, the character of a plant can be used as a step in conservation, cultivation, and germplasm efforts. One solution is to characterize the morphology of these plants. This study aims to analyze and determine the morphological characters of C. nucifera from Bone Selayar Islands district. This research was conducted in the mountainous area of ​​Bone Regency and the coastal area of ​​Selayar Islands Regency. The coconut plant samples observed were deep type coconut plants (C. nucifera L. var typical). Each area was observed as many as 10 accessions of C. nucifera which were randomly selected in the farmer's. The object of the analysis used a descriptive method based on the International Plant Genetic Resources Institute (IPGRI) coconut descriptor manual (International Plant Genetic Resources). The sampling technique was carried out by accidental sampling. Morphological characters C. nucifera observed were tree height, stem diameter, number of fruits, fruit size, and leaf color. The results showed that coconut plants from Bone and the Selayar Islands generally had almost the same morphological characters, the only difference

Abstract

The bioactive compounds from plant based have been raised to control a serious threat by stored-product pests as an established strategy to replace problems in insecticide residues. However, Piper nigrum cultivated in tropical Indonesia which is expected to be a potential bioinsecticide, remains poorly explored. This study aimed to examine the effect of different powdered plants of P. nigrum in each dose on the mortality and the repellency of Sitophilus oryzae in stored rice. Our study carried out a completely randomized design with two factors: (1) powder sources (stems, leaves, fruits) of P. nigrum and (2) their concentrations (2, 3, 4, and 5 g). A dual-choice bio-assay apparatus was designed to measure the treatments A high dose of 5g powdered fruits rapidly caused the highest mortality by 98.3% at 9-d exposure, followed by 4g of powdered fruits by 100% at 12-d. Powdered leaves of 4g and 5g showed a high rapidly repellent potency which were 56.7% and 58.8% after 12-d, respectively. Thereby, the increased doses of fruits and leaves powders of P. nigrum were likely the best innocuous alternative as a low-cost and eco-friendly bioinsecticide agents on S. oryzae.
