Abstract

Sondaken Village has three mangrove zones, each with its own type of plant. The first zone, facing directly towards the sea, is dominated by Avicennia sp. The second zone, in the middle, is characterized by Rizophora sp. The third zone, closer to the land, is predominantly Bruguiera sp. Mangroves have different levels of growth, including seedling level, stake level, pole level, and tree level. The purpose of this study was to determine the types and growth levels of mangroves within its zonation in Sondaken Village, which is part of Bunaken National Park Area. This was done using exploratory and descriptive survey methods, by creating 3 plots in each zone from the edge to the center, with sizes of 10x10 m2, 5x5 m2, and 2x2 m2. The research found that mangrove in Sondaken Village consist of Avicennia sp, Rizophora sp, and Bruguiera sp, with the number of individuals per species being 124, 133, and 113 individuals respectively. Each type of mangrove has different growth levels and numbers.

Abstract

Entog Dwarf coconut is a national superior variety. The purpose of this study was to determine the vegetative growth of Entog Dwarf coconut at 7-10 months of age. The research was conducted at the Palm Plant Research Institute in Manado (Upper Kima Experimental Garden and Ecophysiology Laboratory) using a factorial group randomized design with 2 factors and 3 replications. The first factor was the planting hole with a depth of 100cm and 60cm. The second factor was compound inorganic fertilizer with doses of 1.5kg, 1.0kg, 0.5kg, and control. Nutrient analysis of soil and leaves without fertilization at 7 and 10 months and after fertilization at 10 months. The results of the analysis of variance at the 5% level showed that planting holes had a significant effect, while compound inorganic fertilizers had a significant effect on vegetative characters. The tallest plants were about 51.2-63.7cm with a dose of 0.5-1.5kg while the shortest was 27.2cm, the largest stem circumference was 10.8-11.3cm with a dose of 0,5kg and 1.5kg while the smallest was 6.42cm, and the largest number of leaves was 3.67 midribs with a dose of 1.5kg while the smallest number was 2.67 midribs, where all vegetative characters were categorized as low in control plants. The interaction between the two factors had no significant effect on vegetative growth. The vegetative characters observed were positively correlated. The results of nutrient analysis of pH, moisture content, organic carbon, nitrogen, phosphorus, potassium, stomatal index, and chlorophyll showed little difference both without fertilization and after fertilization.

Abstract

Abstract. Chili (Capsicum annuum L.) is a vegetable commodity with considerable economic value. Agricultural soil that hardens, has a high clay content, does not respond to fertilization, reacts sourly, and is poor in nutrient elements and organic matter, causing many agricultural lands to be less productive and even no longer productive. This research aims to determine whether there is an effect of providing Jakaba biofertilizer on the growth of chili plants. This research used a Completely Randomized Design (CRD) with a factorial pattern consisting of 2 factors and 5 replications. The first factor is the fertilizer dose (D), which includes D0 (without fertilizer), D5 (fertilizer dose 5 ml/plant), D10 (fertilizer dose 10 ml/plant), D15 (fertilizer dose 15 ml/plant), D20 (fertilizer dose 20 ml/plant), and D25 (fertilizer dose 25 ml/plant)-planting media (M), which consists of M1 (soil) and M2 (soil: Jakaba = 1: 1), is the second component. Plant height is measured in centimeters, while the number of leaves is calculated in strands. The results of the research obtained show that there was an influence that can be seen from the combination of doses of biofertilizer and planting media on the vegetative growth of chili plants, namely the observation of plant height in the 4th week of M2D25 treatment has a value The highest is 10.18 ± 0.19 compared to other treatments, so that based on the Kolmogorov test and followed by the Anova test, it has a significant degree of 0.05, which means Ho is accepted and Ha is rejected. Then, when observing the number of leaves, we looked at the 4th week where the M2D20 treatment had the highest average number of leaves, namely 8.6 ± 0.55 compared to other treatments. So, based on the Kolmogorov test followed by the Anova test, it has a significant degree of 0.05, saying that Ho is accepted and Ha is rejected.

Abstract

Blood glucose is a term that refers to the glucose level in the blood. The food type and physiological functions of the body can increase blood glucose. The right food can maintain stable blood sugar. One food source that can maintain stable blood sugar is tubers. One of them is daluga tubers which have a low glycemic index value. This study aims to determine the effect of giving composites made from daluga tubers for 42 days on the blood glucose levels of white rats (Rattus norvegicus). This study used a completely randomized experimental design with nine treatments and three replications. An experimental animal was given 30 g of food each day for 42 days based on the group of treatments. The drinking water was given ad libitum. Blood glucose was measured on days 21 and 42. The results showed that providing daluga-based composite feed to mice affected blood glucose levels (p<0.05). The feeding treatment was 100% composite 3 consisting of 30% daluga flour, 40% rice flour, and 30% corn flour, a daluga-based food can potentially be a food ingredient that can maintain stable blood glucose levels. So it can be concluded that composite 3 could be safe to consume by the diabetes patient.

Abstract

Sea urchins are organisms that have antibacterial, antitumor, and anticancer abilities. The gonads can be used as a food source because they store 28 kinds of amino acids, vitamin B complex. This research aims to determine the type of bacteria from the gonads of sea urchins (Diadema setosum) which have inhibitory power against the growth of Pseudomonas fluorescens and Staphylococcus aureus bacteria. This research used an exploratory method which was analyzed descriptively, using stages in which sea urchin samples were taken and antibacterial tests against Pseudomonas fluorescens and Staphylococcus aureus from sea urchin gonads using the spread method. The media used for the process of isolating bacteria from the gonads of the sea urchin Diadema setosum is Nutrient Agar (NA) media. Isolate colonies that grew after incubation for 24 hours were separated based on differences in colony morphology. Morphological characterization of bacterial cells begins with gram staining. The diameter of the inhibition zone in the test bacteria shows different shapes. The research obtained 8 bacterial isolates, namely isolates B1-B8 which were gram-negative. The eight bacterial isolates have the potential as antibacterials against the test bacteria P. fluorescens and S. aureus. Isolates B1, B2, B3, B7 are similar to the genus Proteus, while isolates B4, B5, B6, and B8 are similar to the genus Citrobacter. The diameter of the largest inhibition zone in the P.fluorescens test bacteria, namely isolate B1, was 9.03 mm. Meanwhile, the smallest diameter for isolate B7 was 6.97 mm. In the S.aureus test bacteria, the largest diameter in isolate B1 was 11.09 mm. Meanwhile, the smallest diameter for isolate B4 was 8.57 mm.

Abstract

Pakoba fruit is one of the endemic flora of North Sulawesi which is rich in nutrients and has the potential to be fermented. The fermentation process occurs due to the bacteria in the fruit, including lactic acid bacteria (LAB). One of the interesting products from LAB fermentation is that it can produce secondary metabolites which have the potential to produce exopolysaccharides, namely high molecular weight and biodegradable polymers. This research aims to determine whether LAB can be obtained from fermentation of Pakoba marination and what types of LAB produce exopolysaccharides based on their phenotypic characteristics. This research uses a qualitative descriptive method to characterize the type of LAB and observe the exopolysaccharides produced by the bacteria. This research succeeded in isolating and identifying 10 LAB isolates based on their morphological and biochemical characters. Four isolates named MP(1)5.2, MP(1)7.1, MP(3)6.3, MP(3)7.2 can produce exopolysaccharides with a soft character but not mucus, where bacterial exopolysaccharides are believed to increase probiotics in the digestive tract. Genus level recognition (generic assignment) based on profile matching revealed that these four bacteria were from the genus Lactobacillus.
