Abstract

This study aims to determine the diversity of fish species in Sulup River, Rimbo Pengadang District, Lebong Regency, Bengkulu. The Research was conducted from in April-May 2020. The method used in this study is a direct survey method. The sampling method used is purposive sampling by dividing the research station into 3 stations based on river conditions. The types of fish found in the Sulup River Rimbo Pangadang District Lebong Regency Bengkulu Province were found as many as 4 orders, 4 families with 8 species namely species Mystus singaringan, Angullia marmorata, Osteochilus vittatus, Hampala macrolepidota, Barbonymus gonionotus, Schismatorhynchos heterorhynchos, Rasbora argyrotaenia and Mastacembelus armatus. The ecological conditions in the Sulup river have a temperature of 230C, a depth of 1.5 m, 45 cm river clarity, water pH 7, flow velocity 0.66 m/sec. Sulup River has a diversity index of 0.840, so the diversity index is low.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

This study aims to determine the diversity of soil surface insects, in the Bukit Gatan area, Musi Rawas Regency. This research is a qualitative descriptive study using a pitfall trap and using a random sampling method. The results showed that the types of ground surface insects contained 3 orders, 5 families and 10 species.The results of the analysis of the ecological index of soil surface insects in the Gatan hill area, Musi Rawas Regency, namely the diversity index (H') 1.241 in the low category, Evennes index (E') 0.64 in the medium category, and the dominance index (C)0.277 in the medium category.The abiotic factors in the Bukit Gatan area, Musi Rawas Regency at the research site are the average air temperature 29℃, average soil pH 6.5, and average soil moisture 85.3%.Diversity of soil surface insects in the Bukit Gatan area, Musi Rawas Regency is in the low category.
