IDENTIFIKASI FENOMENA SELF-INCOMPATIBILITY PADA Hibiscus rosa-sinensis L.

Hybridization is one way to produce Hibiscus rosa-sinensis L. which have various shape and colour of flowers. However, this is hampered by the possibility of self-incompatibility in Hibiscus rosa-sinensis L. To identify self-incompatibility in Hibiscus rosa-sinensis L. the simplest methods are used by observing the morphology and anatomy of fruit development, followed by a descriptive analysis of the data that has been obtained. The analysis results on crossing artificial pollination to 103 flowers of single pink Hibiscus rosa-sinensis L. show that the fruits survive until day 7 after pollination. Furthermore, the data show that there is no fruit, seed, and embryo development. Indeed the fruit turns yellow and finally shed. But the self artificial pollination shows that 35 seeds develop from 96 pollinations. The longer seed, which 13 days after pollination, grew up. The globular embryo could find on 3 DAP (day after pollination) fruit set, and the 9 DAP fruit set shows the development of heart shape. The result suggests that the phenomenon of self-incompatibility on Hibiscus rosa sinensis L. predicts as postzygotic self-incompatibility.

PENGARUH WAKTU PENUNDAAN PENGOLAHAN BUAH SAWIT Elaeis guineensis TERHADAP MUTU CRUDE PALM OIL DENGAN ALAT PENGOLAHAN SAWIT TIPE BATCH

This study aims to Analyze the effect of time delay on processing of palm fruit from Elaeis guineensis Jacq to Crude Palm Oil (CPO) quality. Fresh fruit marks are chopped to separate with fruit marks in the form of brondolan, then separated between inside and outside fruit and then treated with processing delays 0 hours, 6 hours, 12 hours, 18 hours and 24 hours. Further processed by using Batch type palm oil processing tool. CPO is analyzed CPO quality which consist of free fatty acid test, water content test and dirt level test. From result of measurement and quality test show the effect of time delay of processing of palm fruit to increase free fatty acid especially at treatment delay for 24 hours on fruit palm inside. The result of comparison of CPO quality measurement (ALB level, moisture content and dirt level) is still far below SNI standard.

KAJIAN STRUKTUR ANATOMI DAN MORFOLOGI DAUN PLANLET PISANG KEPOK KUNING HASIL PEMBERIAN EKSTRAK UMBI KEMBANG SUNGSANG SECARA IN VITRO

Plantain is a fruit commodity that has a high level of market demand, but the yield is low. To overcome this problem, tissue culture techniques are used to increase plantlet production in a short time. Plantain have parthenocarpy character, high sterility, and different levels of ploidy. Tissue culture with the addition of flame lily tuber biomutagen containing colchicine was used as a strategy to overcome the above constraints because it was thought to increase the production of polyploid banana plantlets. Changes in the anatomical and morphological structures are indicators of polyploidy. The purpose of this study was to obtain information on changes in the anatomical and morphological structures of plantain leaves as a result of giving in vitro plantlet propagation media as an indicator of the formation of polyploidy. Plantlets were grown on tissue culture media supplemented with three treatments: 10% flame lily tuber extract, 0.1% pure colchicine, and without addition (control). The parameters observed were epidermal cell size, stomata size, stomata index, number and leaf area. Epidermal cell size, stomata size and stomatal index were analyzed using range values ​​and mean values. The number of leaves, and the average wide of leaf, is then shown in the form of a bar chart. The results showed that administration of flame lily tuber extract was able to increase epidermal cell size, stomata size, wide of a leaf, and able to reduce the stomata index and number of leaves.
