Abstract

Indonesia has many endemic butterfly species and there are about 2,000 species found in Indonesia from 17,500 species of butterflies in the world. This research was conducted for five months from January to May 2017 at Cibodas Botanical Garden of Cianjur Regency, West Java. Technique of taking data is done by butterfly captured directly by insect net in each observation point. The observation of butterflies in the three locations of Sakura Park, Guest House and Fountain at Cibodas Botanical Garden found 98 individuals from 21 species consisting of 4 families, among others Papilionidae (4 species), Nymphalidae (12 species), Pieridae ( 4 species), and Lycaenidae (1 species). At the location of Sakura Park has the highest index value, among others, the species diversity index (H '= 1.92) is moderate, the species richness index (R = 3.51), and the dominance index (C = 0.27), while the species evenness index highest at the Fountain location (E = 0.87). Students are rarely invited to visit KRC to learn directly.

Abstract

Impatiens hawkeri x platypetala rooted cuttings are typically cultivated using rice husks as a substrate. However, due to the poor water-holding capacity of this medium, Impatiens grows slowly in this environment. A viable alternative is the cocopeat perlite mixture which has a better water-holding capacity compared to the rice husk. Currently, there is no sufficient information available regarding the best growth medium to improve the quality of I. hawkeri x platypetala rooted cuttings in Indonesia. Therefore, this study aimed to obtain the best medium for quality rooted cuttings I. hawkeri x platypetala. The method employed was a randomized complete block design with two factors. The first factor was the Impatiens varieties consisting of Impala Agrihorti, Imadata Agrihorti, and Lavender, while the second was the growth medium, comprised of four levels namely rice husk (control), as well as a mixture of cocopeat with 3%, 5% and 8% perlite. The result showed that there was no interaction between varieties and growth medium. The mixture of 3% perlite in cocopeat exhibited better outcomes compared to other treatments. This medium increased the number and length of roots, stem diameter, plant height, leaves thickness, leaves number and survival rate. Therefore, the addition of 3% perlite in cocopeat could replace the rice husk as a rooted cutting growth medium for I. hawkeri x platypetala.
