Abstract

Badan Pusat Statistik reported that rice production in 2019 decreased by 2.63 million tons (7.75 percent) when compared to 2018 production. Efforts to increase national rice production can be made by utilizing swamp land as rice production land. The high concentration of Fe in swamp land is an obstacle in its utilization. Selection of iron stress tolerant rice strains is needed . The purpose of this study was to determine the iron stress tolerant swamp rice strains and the relationship of tolerance levels in rice strains based on SSR (Simple Sequence Repeats) and SNP (Single Nucleotide Polymorphism) markers. The results showed that the rice strains tolerant to 1600 ppm FeSO4 stress was Siam Saba. Four of the 11 SSR markers used showed polymorphism, namely RM 125, RM 180, RM 320, RM 336. Cluster analysis showed that 4 rice strains were divided into 2 main groups with a similarity coefficient of 0.66. The first group consists of swamp rice (Siam Saba and Siam Tanggung) and the second group consists of paddy rice (Ciherang and INPARI 34). Analysis with SNP markers showed 12 SNP points. There was a deletion mutation at position 1007 bp and an insertion mutation at position 1151 bp.

Abstract

Production of gourami as consumption fish is rather lengthy, as it attains commercial size in 1—2 years, longer than other commercial fish. Therefore, fish production is hampered by higher fodder costs. It is a normal practice in gourami rearing, that farmers supplement commercial fodder with naturally available fodder, especially from material such as taro leaves. However, some materials may contain less nutrients, compared to others. It is why we propose the use of Lemna perpusilla, a widely distributed water aroid as gourami fodder supplement. We measured the growth of gourami fries, which are length (cm) and weight (g) and found that fishes with L. perpussila pellet attain higher length and weight compared to those using commercial pellet. This research may be beneficial for freshwater weed management as well as fish production with low capital, i.e. village production.

Abstract

In addition to urban forest area at the University of Indonesia, Depok Campus, West Java, there are lakes that functions as water reservoir area. University of Indonesia is eager to create green and beautiful campus environment with one of its efforts is to care for the lake ecosystem in the campus. This study was conducted to analyze the diversity of phytoplankton in the lake. Sampling was carried out by determining 3 location points with 3 times repetitions conducted on different days. The water samples taken were then identified at the Biology Laboratory FMIPA UNJ. The mean values of water quality parameters obtained were pH 10, TDS 90 ppm, temperature 30°C, and water clarity 46 cm. The results showed that 14 genera and 20 species have been found, they are Chlorophyta, Chroococcus, Coelosphaerium, Crucigeniella, Euglena, Gloeocapsa, Merismopedia, Pediastrum (3 species), Peridinium, Scenedesmus (4 species), Tablelaria, Tetrastrum, Volvox, and Westella (2 species). The Diversity Index Shannon-Wiener during the observation was 2.9, which means that the condition of water at the University of Indonesia Lake was very good and not polluted. The availability of phytoplankton in the area was generally sufficient which can be utilized by other organisms as food source.

Abstract

Long-tailed macaque (Macaca fascicularis) is one species of wild animals inhabits Muara Angke Wildlife Reserve (SMMA), a wetland reserve predominantly grown by mangrove swamp forest. As there is high encounter of M. fascicularis with human and high incident of human-given food, it is important to understand the composition of natural food of M. fascicularis. The method used was quantitative with data collection techniques using scan sampling technique with 5-minute intervals. Natural food source for M. fascicularis in SMMA is provided by 17 species of plants. The main natural food sources providing both leaves and fruits are Ficus benjamina (54.62%) and Sonneratia caseolaris (28.9%). The most common plant parts eaten by M. fascicularis are leaves (61%) and fruit (21%), resembles to those of leaf monkeys (langurs). However, is a high possibility that nutrient needed to supplement high leaf consumption in SMMA monkeys is provided by non-natural human-given food.

Abstract

Continuous use of blue swimming crab (Portunus pelagicus) without any control can cause population decline which leads to damage to the stability of the marine ecosystem, especially in East Coast Pangandaran, therefore cultivation is needed. In aquaculture, it is necessary to provide the right feed by knowing its natural diet. This study aimed to determine the natural diet of blue swimming crabs. The method used was descriptive analysis. The parameters observed were carapace width, gastric weight, the composition of natural diet. The relationship between the carapace width and gastric weight was analyzed by simple regression while the main type of natural diet was known by calculating the percentage of food composition. The relationship between carapace width and gastric weight was positive. Based on the composition found in crab gastric, there were 5 types of natural foods consisting of crustaceans (28.35%), meat (25.37%), mollusk (18.65%), fish (15.67%), and undefined material (UM) (4.47%). It is revealed that crabs are carnivores and scavengers, pose significant relationship between their size and gut content weight. It was also found that the composition of female crab feed was generally higher than that of males.

Abstract

Cyclin-dependent kinase 5 (Cdk5) is a serine/threonine protein kinase, which forms the p35 or p39 active complex that is expressed predominantly in neurons. Cdk5 plays an important role in physiological functions in non-neural cells such as glucose-stimulated insulin secretion in pancreatic cells. This study aims to explore and determine the effectiveness of the chemical compound Oleracein E (OL-E) in the Portulaca oleracea (PO) as an anti- diabetic when expressed on Cdk5 protein. The test was carried out in silico with a computer- aided drug design method in which the molecular docking process used software such as Pyrx 0.8. The results of this study indicate that OL-E has the potential as an antidiabetic by inhibiting Cdk5 and has 27.65% better effectiveness than metformin in inhibiting Cdk5.

Abstract

As Indonesia is known as a megabiodiversity country, and Sumatra is its second largest island, it is important to understand its ever-threatened plant biodiversity, including those managed locally as village forests. In Serdang Village Forest, Barusjahe, Karo, North Sumatra, we tried to list all the liana species and their phorophytes. We conducted a qualitative descriptive analysis of the lianas and their phorophytes in the study area and found There are 25 species of lianas from 14 families Mostly are leaners, followed by tendril climbers, root climbers, hook climbers, thorn climbers and twiners. They climbed on 8 species of phorophyte from 8 families, most commonly tall forest trees. This study enhances our understanding of the lianas and their phorophytes in the Serdang Village Forest, which can aid conservation efforts to preserve biodiversity.

Abstract

The reduction in the quantity and quality of food can occur during storage in warehouses due to the infestation of rice weevils (Sitophilus oryzae). Environmentally friendly control methods for rice weevil pests are needed, such as using botanical insecticides made from fragrant pandan leaf powder. This research aimed to determine the effects of fragrant pandan leaf powder insecticide on rice weevil pests. The research design used was a non-factorial Completely Randomized Design (CRD) utilizing four dosage levels: 15, 30, 45, and 60 g. The results showed that the dosages had a significant effect on rice weevil mortality, with the highest mortality rate found at the 60 g dosage, reaching 43.50%. The implications of the findings indicated that while higher doses of fragrant pandan leaf powder (60 g) significantly increase rice weevil mortality and also lead to rice weight loss, a balanced dose of bio-insecticide is needed to avoid excessive damage to the rice. Additionally, the organoleptic test results indicate that lower doses (15 g and 30 g) are more preferred by consumers for color, taste, and aroma, which implies that careful dosage control is crucial for both pest control effectiveness and maintaining consumer acceptance.
