Abstract

The condition of seagrass beds in Amahai Bay is relatively fertile, with a fairly high and wide density. Enhalus acoroides was chosen as a type of seagrass used for transplants in this study because Enhalus acoroides was quite abundant in the waters of Amahai Bay. Seed availability is one of the factors that need to be considered in the transplant business. There are several points in the waters of Amahai Bay where seagrass conditions do not grow evenly. Many fishermen who do fishing activities in the seagrass area inadvertently damage the ecosystem in the seagrass beds in that location. Under these conditions, it is important to do seagrass transplants so that the seagrass ecosystem is not increasingly damaged due to many human activities or natural factors. This experimental field research was carried out comparing the growth of transplanted seagrass Enhalus acoroides using the anchored sprig method. Determination of the location of the study carried out by the method of purposive random sampling. The research station in the waters of the village of Amahai at the substrate location of the muddy sand bottom with a depth of 0.85-1.5m. The station is divided into 3 observation points, with each location given 3 plots of 1x1m size with a transplant of 16 stands in each plot. The highest leaf growth rate for transplanted seagrass is at station 2, which is 3.76 mm.hr-1 on young leaves and 1.86 mm.day-1 for old leaves. And there is a difference in the speed of growth between the growth of natural seagrass and transplanted seagrass. The difference in transplantation stations has a very significant effect on the growth of seagrass leaves.

Abstract

This study aims to determine the effectiveness of the fruit filtrate of the Phaleria macro as bioinsecticide for the larvae of Maruca testulalis in long bean plants Vigna unguiculata. This research was conducted at the Integrated Science Laboratory of STKIP Muhammadiyah Manokwari in June 2019. The population used in this study was 150 larvae of Maruca testulalis. 7 treatment groups were consisting of 4 replications. The P0 treatment group was given 0.1 ml of reagent solution, then for treatment P1, P2, P3, P4, P5, and P6 each was given the filtrate from the Phaleria macro with a concentration of 20%, 30%, 40%, 50%, 60%, 70%. The results of data analysis using the Kruskal-Wallis test 5.708 <12.591 so that there was no effect of the bioinsecticide of the crown of gods on the larvae of Phaleria macro these results are influenced by the dose concentration that is not quite right. However, if it is seen from the results of the research data, it can be seen that there is an effect of giving the Phaleria macro fruit filtrate on the mortality of Maruca testulalis larvae. This effect is due to the presence of saponin compounds found in the Phaleria macro.

Abstract

The research was conducted in the Maruni limestone forest habitat. The observation plots were carried out at an altitude of 35 masl to> 212 masl. Observations were made 2 times every day (day and night). The method of calculating diversity is done using the Shannon-Wieners Index and the species population is calculated using the Alikodra formula. 11 species were found that belong to the Varanidae, Boidae, Gekkonidae, Ranidae, and Hylidae families. The diversity of wildlife in the Maruni limestone location follows the altitude of the habitat. Reptiles do not differ according to height. The most common types are in the class of lizards, monitor lizards, and frogs. The types of herpetofauna that can be found are carnivores and are not protected. This type of monitor lizard can be found in abundance in low areas to an altitude of> 200 meters above sea level. Meanwhile, monitor lizards can be found in wet forests and near water sources. Similar to lizards, frogs inhabit wet or watery areas. The diversity of wildlife species in limestone habitats in each class of Reptiles is 18%. The population of herpetofauna species found varied between 25-1200 individuals.

Abstract

This study aims to determine the effect of the water boiled leaves of Clidemia hirta on blood sugar levels in Swiss Webster mice (Mus musculus). This research using a completely randomized design research design (CRD) with 5 treatment groups namely; Aquades control group (P0), 3 g sucrose treatment (P1), 3 g sucrose treatment + boiled bristle leaves boiled water at a dose of 0.13 ml/KgBB (P2), 3 g sucrose treatment + boiled bristle leaves boiled water at a dose of 0.26 ml/KgBB (P3), 3 g treatment of sucrose + boiled bristle leaves boiled water at a dose of 0.39 ml/KgBB (P4). Before administration of the extract, mice in the treatment groups P1, P2, P3 & P4 were induced using 3 g of sucrose for 5 days. Then after 5 days for groups P2, P3, and P4 followed by giving boiled water leaves for 7 days. The analysis result of One Way Anova Test shows that Fcount > Ftable (18.86 > 2.51). This shows the boiled water affects the blood sugar levels of male Swiss Webster mice. The concentration of extract at P4 (0.39 ml/KgBB) was more effective in reducing blood sugar levels.

Abstract

This study aims to determine the effect of giving boiled water leaves Clidemia hirta on the levels of male webster swiss mice cholesterol. This type of research is an experimental study using the Completely Randomized Design (CRD) method which consists of 5 treatments with 5 repetitions. The experimental animals in this study were male mice which were divided into 5 groups namely P0 (aquadest), P1 (MDLT + PTU + boiled water 0.13 ml/bb), P2 (MDLT + PTU + boiled water 0.26 ml/bb), P3 (MDLT + PTU + boiled water 0.39 ml/bb), and P4 (Simvastatin 10 mg). The treatment was carried out using the gavage method using a gastric sonde device, giving boiled bristle leaves boiled water in the morning for 7 consecutive days carried out in the morning. Retrieval of blood cholesterol levels data by cutting the tail of mice and the next drop blood on the cholesterol strip Autocheck tool. Based on the results of the Kruskal Wallis test calculation states that Hcount <Htable (4.626 <9.49), it can be concluded that the provision of boiled water leaves of Clidemia hirta does no effect significant in reducing levels of male Swiss Webster mice (Mus musculus) cholesterol levels.

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.
