Abstract

The snake-head gudgeon or payangka fish (Ophieleotris aporos), tilapia fish or mujair (Oreochromis mossambicus), and marble goby or betutu fish (Oxyeleotris marmorata) are economically important fish in Lake Tondano. However, numerous community activities can disrupt aquatic biodiversity, declining Lake Tondano environmental conditions, and other factors. This study aimed to determine the relationship between length and weight and the habitat conditions of Ophieleotris aporos, Oreochromis mossambicus, and Oxyeleotris marmorata. The method used in this study was purposive sampling with research stations located at Remboken (station 1), Kakas (station 2), and Tondano Estuary (station 3). Sampling was carried out 5 times in every 10 days. The weight and length of the fishes caught in Lake Tondano were 2-60 g and 1-8 cm (Ophieleotris aporos); 9-180 g and 6-25.5 cm (Oreochromis mossambicus); and 16-30 g and 2.6-26.5 cm (Oxyeletotris marmorata), all of them have an allometric growth pattern. Oreochromis mossambicus is the most commonly caught fish in all research stations. The research station with the best level of water fertility is Remboken Station. The habitat characteristic of Lake Tondano was 25-290C of water temperature; brightness of 1.34-2.66 m; depth of 4.23-11.8 m; pH of 6.7-7.8; and dissolved oxygen of 2.27-6.31 mg/L, which still supports the well-being of the fish.

Abstract

Papaya (Carica papaya L.) is one of the agricultural commodities that is widely cultivated by farmers in almost all parts of Indonesia. This plant is widely cultivated because varied consumption of papaya by the community makes the demand for fresh papaya fruit in the market always increase. Therefore, the cultivation of this plant is very important to be applied properly. Cocopeat is a powder which is a waste of coconut coir processing. Our previous research has shown that cocopeat is an organic material that has a positive role in the growth of patchouli seedlings. This study aimed to examine how the effect of the addition of cocopeat on the quality and quantity of growth of papaya seedlings (Carica papaya L.var.calina) on experimental land within the Universitas Negeri Manado (Unima) campus in Tondano. Experimental research was carried out with one factor, the concentration of cocopeat, with 5 levels 10, 20, 30, 40 and 50%. The control used was an organic media compounded by the analysis without using cocopeat. Each treatment and control was repeated 30 times so that the number of experimental units was 180 experimental units. Randomization was carried out by placing 10 rows and 18 columns at the Unima Patchouli Nursery Installation. The quantity parameter is the number of days the seeds germinated and the number of seeds that were successfully germinated in each treatment and control. Quality parameters include seedling height at the age of 2 months after germination (first germination); number of leaves, leaf size, wet weight and dry weight at 2 months of age. Based on the results, it can be concluded that the use of organic media with the addition of cocopeat at a concentration of 10-50% had a significant effect on leaf number, leaf size, plant height, stem diameter, wet weight, and dry weight of papaya plants in the early growth period. The addition of cocopeat concentration in the growing media will have an increasing effect on the observed parameters. Especially for the parameter of the number of days of germination after planting did not show a significant difference between all treatments.

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.
