Abstract

AbstrakHibiscus rosa-sinensis L. atau kembang sepatu merupakan tanaman hias yang memiliki banyak manfaat dan merepresentasikan sifat poliploidi. Tujuan penelitian ini yaitu untuk mengetahui Indeks Mitosis (IM) dan jumlah kromosom pucuk daun H. rosa-sinensis pada beberapa variasi waktu. Indeks Mitosis dan waktu pengambilan pucuk sangat diperlukan untuk studi kromosom karena pada tahap tersebut karakter-karakter kromosom dapat diamati dengan jelas dan mudah dihitung. Waktu pengambilan pucuk yang dilakukan yaitu pada 08:00, 10:00, 12:00, 14:00, 16:00 WIB. Pembuatan sediaan kromosom dilakukan menggunakan metode squash menggunakan pewarna Aceto-orcein. Tahapan perlakuan meliputi perendaman pucuk daun di dalam air dingin selama 3 jam, fiksasi dalam larutan Carnoy selama ±24 jam, dan hidrolisis dalam larutan HCl 5N selama 30 menit. Hasil penelitian menunjukkan nilai IM tertinggi meristem pucuk daun H. rosa-sinensis variasi single pink besar muncul pada pukul 10:00 sebesar 94%. Berdasarkan hasil tersebut dapat disimpulkan bahwa waktu sampling yang optimal untuk analisis kromosom H. rosa-sinensis L. variasi single pink besar adalah pukul 10:00 dengan jumlah kromosom 2n= ca. 69-111.  Hasil penelitian ini dapat dijadikan dasar untuk studi kromosom selanjutnya serta acuan untuk sampling variasi lainnya.Abstract Hibiscus rosa-sinensis L. is an ornamental plant that has many benefits and represents the character of polyploidy. The purpose of this study is to find out the Mitotic Index of leaf shoots Hibiscus rosa-sinensis on several shoots sampling times. The Mitotic Index and the timing of shoots sampling time are very necessary for chromosome studies because at this stage chromosomes characters can be clearly observed and easily calculated. Period time of collection the leaf shoots is from 08:00 AM to 16:00 PM, with two hours interval each at 08:00, 10:00, 12:00, 14:00, 16:00 . The chromosome preparation was carried out by using the squash method and aceto-orcein staining. The treatment steps included soaking the leaf shoots in cold water for 3 hours, fixation in Carnoy solution for ± 24 hours, and hydrolysis in 5N HCl solution for 30 minutes. The results showed that chromosomes were clearly visualized during the phase with the highest Mitotic Index.  In addition, the percentage of Mitotic Index was found to be in line with the percentage of cells in late prophase. Among several sampling time variations, the highest Mitotic Index of Hibiscus rosa-sinensis leaf shoots appeared at 10:00 at 94% with the chromosome numbers of 2n= ca. 69-111. According to the data obtained, it is concluded that 10 AM is the most optimum sampling time that can be used as the basic information for further chromosome studies.

Abstract

AbstrakPermukiman merupakan salah satu ruang terbuka hijau (RTH) yang terdapat di daerah urban, khususnya Jakarta. Salah satu kelompok tumbuhan yang ditemui pada RTH tersebut adalah lumut. Keberadaan lumut di permukiman urban menunjukkan adanya kemampuan lumut untuk bertahan pada lingkungan yang terganggu. Penelitian ini bertujuan untuk mengetahui spesies lumut serta karakteristik lumut di salah satu permukiman Jakarta Selatan. Lumut dikoleksi dengan metode transect-line pada 6 titik tepi jalan dan jelajah bebas pada 3 taman di permukiman tersebut Jakarta Selatan. Pengamatan karakteristik morfologi dan anatomi lumut dilakukan dengan penilaian kualitatif dan kuantitatif. Berdasarkan hasil penelitian terdapat 2 divisi lumut, yaitu Bryophyta (lumut sejati) dan Marchantiophyta (lumut hati) di lokasi penelitian. Bryophyta terdiri dari 6 famili, 9 genus, dan 16 spesies. Sementara itu,  Marchantiophyta terdiri dari 2 famili, 2 genus, dan 3 spesies. Pottiaceae merupakan famili dengan jumlah spesies terbanyak ditemukan, yaitu 5 spesies. Fissidens biformis adalah spesies dengan jumlah sampel terbanyak. Lumut tersebut ditemukan pada substrat tanah, batu, dan batang pohon. Kisaran luas tutupan lumut yang ditemukan yaitu 2–100%. Karakteristik seperti ukuran tubuh yang kecil, bentuk hidup, bentuk daun, ornamentasi pada permukaan daun, modifikasi sel daun, serta keberadaan sporofit atau gemma diduga mendukung lumut beradaptasi di lingkungan urban.AbstractSettlement is one of urban green open spaces in Jakarta. One of the plant groups found in the open green spaces is the bryophytes. The presence of bryophytes in the settlement areas indicates the ability of bryophytes to survive in a disturbed environment. This study aims to determine bryophytes species and their characteristic in the settlements area of South Jakarta. Bryophyte collected by transect-line at 6 sites of roadside and broad survey at 3 sites of park. The morphological and anatomical characteristics were observed with qualitative and quantitative assessments. Mosses and liverworts are groups that found in study sites. The mosses consists of 6 families, 9 genera, and 16 species. Meanwhile, the liverworts consists of 2 families, 2 genera, and 3 species. Pottiaceae is has the highest species richness in the location. Meanwhile the highest number of samples was Fissidens biformis. The bryophytes were attached in the soil, rock, and tree trunk. The coverage of bryophyte is about 2–100%. Characteristics such as small body size, life-forms, leaf shape, the ornamentation on the leaf surface, modified leaf cells, and the presence of sporophyte or gemmae are thought to support the adaptation of bryophyte in urban environments.
