"Penelitian mengenai karakterisasi morofologi bunga dan pollinaria 14 spesies Hoya atau bunga lilin telah dilakukan dari Februari--Mei 2015. Penelitian bertujuan untuk mendeskripsikan dan membandingkan 14 spesies Hoya koleksi Kebun Raya Bogor (KRB) berdasarkan morfologi bunga dan pollinaria. Sampel yang digunakan merupakan 14 spesimen awetan basah bunga koleksi KRB. Data yang diambil berupa data kualitatif, kuantitatif, dan visual melalui metode pengamatan langsung. Hasil penelitian menunjukkan variasi bentuk dan ukuran bunga serta pollinaria pada 14 spesies Hoya koleksi KRB. Hasil juga menunjukkan adanya karakter pembeda antarspesies yaitu bentuk calyx, keberadaan trikom pada bagian tepi calyx, bentuk corolla, bentuk corona, pelengkap anther, bentuk pollinia, bentuk corpusculum, ada atau tidaknya caudicle, bentuk caudicle, ada atau tidaknya pellucid edge, dan bentuk translator.

Research on morphological flowers and pollinaria characterization from 14 species Hoya or wax flowers was conducted from Februari--Mei 2015. The aims of this research was to describe and compare 14 species of Hoya collections from Bogor Botanical Garden (BBG) based on flower and pollinaria morphology. The research was carried out using preserved 14 specimen collections from BBG. The qualitative, quantitative, and visual data were collected by direct observation method.

The result showed that the shape and size characters from flowers and pollinaria of 14 Hoya species from BBG were varied. Beside variation of Hoya flowers and pollinaria, there were also some distinguish characters of calyx shape, presence or absence of trichome in calyx, corolla shape, corona shape, anther appendages, pollinia shape, corpusculum shape, presence or absence of caudicle, caudicle shape, presence or absence of pellucid edge , and translator shape."

"This researches tries to review the actual assesment of Bogor Garden Performance as tourist attractions using tri hita karana concept and coorporate social responsibility (CSR) principles. the Implementation of Tri hita karana has been done in harmony with local wisdorn , whilst the CSR is supported by private corporations"

"Hibiscus rosa-sinensis memiliki variasi pada bentuk bunga single, crested, dan double. Variasi tersebut disebabkan adanya perubahan struktur stamen menjadi bentuk lembaran (petaloid) pada bunga crested dan double. Pembentukan struktur petaloid tersebut merupakan gejala homeosis yang disebabkan oleh mutasi pada gen homeotik pengatur identitas organ bunga. Gen homeotik bunga termasuk ke dalam kelompok gen MADS-box yang dibedakan berdasarkan fungsinya menjadi gen kelas A, B, C, D, dan E. Gen yang berfungsi dalam mengatur pembentukan identitas stamen adalah gen kelas B, C, dan E. Penelitian ini bertujuan untuk menganalisis gen APETALA3 dan PISTILLATA (kelas B), AGAMOUS (kelas C), serta SEPALLATA1 (kelas E) pada petal dan struktur stamen bunga H. rosa-sinensis variasi single, crested, dan double, serta mengetahui homologi gen-gen tersebut dengan gen-gen ortolog pada spesies tumbuhan yang berbeda. Isolasi DNA genomik dilakukan menggunakan kit ekstraksi DNA genomik. Selanjutnya, amplifikasi gen dilakukan menggunakan primer AP3, PI, AG-1, AG-2, AG Kombinasi 1 dan 2, SEP1-1, dan SEP1-2. Sekuensing dilakukan pada amplikon gen yang berhasil diamplifikasi, yaitu pada amplikon gen PI, AG-1, AG Kombinasi 1, SEP1-1, SEP1-2. Hasil sekuensing berkualitas tinggi diperoleh dari amplikon gen PI, AG Kombinasi 1, dan SEP1-2. Penyejajaran sekuens gen yang diperoleh dengan gen target menunjukkan persentase kemiripan yang rendah. Hal tersebut dapat terjadi karena adanya perubahan sekuens gen MADS-box akibat proses evolusi tumbuhan. Oleh karena itu, desain primer untuk mendapatkan sekuens target perlu dilakukan kembali dengan mempertimbangkan kemungkinan diversifikasi gen MADS-box pada spesies tumbuhan yang berbeda.

Hibiscus rosa-sinensis has variations in the form of single, crested, and double flowers. This variation is caused by a change in stamen structure to form petaloids in crested and double flowers. The formation of these petaloid structures is a symptom of homeosis caused by mutations in homeotic genes that regulate flower organ identity. Flower homeotic genes belong to the MADS-box gene group which are distinguished based on their function into A-, B-, C-, D-, and E-class genes. The genes that function in regulating the formation of stamen identity are B-, C-, and E-class genes. This research is done to analyze the APETALA3 and PISTILLATA (B-class), AGAMOUS (C-class), and SEPALATA1 (E-class) genes in the petal and stamen structure of single, crested, and double H. rosa-sinensis flower variations, as well as to know the homology of these genes with other ortholog genes from different plant species. Genomic DNA isolation was carried out using an extraction kit. Next, gene amplification was performed using primers AP3, PI, AG-1, AG-2, AG Combinations 1 and 2, SEP1-1, and SEP1-2. Sequencing was carried out on the amplicons of the genes that were successfully amplified, namely the amplicons of the PI, AG-1, AG Combination 1, SEP1-1, SEP1-2 genes. High quality sequencing results were obtained from the amplicons of the PI, AG Combination 1, and SEP1-2 genes. Sequence alignment between obtained and target genes showed a low percent similarity. This can occur due to changes in the MADS-box gene sequence caused by the process of plant evolution. Therefore, primer redesign to obtain target sequences needs to be done by considering the possibility of MADS-box gene diversification in different plant species."

"Amorphophallus borneensis is endemic species from Kalimantan, belongs to the Araceae family. It is included as one of the giant Amorphophallus. This species is indicated by the unique pattern of the petiole and peduncle which resembles the comple patterns of lihen on the stem. The distribution of A. Borneensis was only known from soutern of Kalimantan. The new localities have been found during Kebun Raya exploration in Central and East Kalimantan."
