Abstract

Chicken eggs are the most widely consumed poultry product. Eggs have high protein value and are affordable for the public. Demand for local chicken eggs continues to increase every year. Merawang chicken and Arabian chicken are local Indonesian chickens. It is hoped that crossing the two chickens will produce superior offspring in egg production. The research was conducted to evaluate egg production in local chickens of the merawangarab cross with different genetic compositions of the merawang (M), namely 25% M, 50% M, 62.5% M, and 75% M, totaling 31 birds consisting of 21 adult females and 10 males. This research used a randomized block design (RAK). Egg production has achieved quite good results. The genetic composition affected egg index (P<0.05), but egg weight, hen day production, and feed conversion were the same. The four types of merawangarab chickens have the potential to be local egg-producing chickens. The egg production performance of 25%M, 50%M, 62.5%M, and 75%M was the same and all four could be developed as local laying hens.

Abstract

Human Immunodeficiency Virus (HIV) type 1 is the predominant strain known for its impact on the immune system and its propensity for mutation. According to the World Health Organization (WHO), the global infection count reached 37.9 million in 2018, with alarming rates of mortality and morbidity. Ongoing drug discovery endeavors encompass various facets, including investigations into HIV protease—a key enzyme in the cleavage process of gag and gag-pol polyprotein chains essential for the genesis of new virions. While numerous studies suggest the inhibitory potential of quercetin against HIV-1, comprehensive exploration regarding its interaction with the HIV-1 protease receptor remains limited. This study aimed to elucidate the therapeutic potential of quercetin derivative compounds as viable candidates for HIV protease inhibition. Employing in silico analysis, molecular docking of 36 quercetin derivative compounds with the HIV-1 protease receptor (code 3SO9) using the Pyrx-Autodock Vina-Open Babel platform was conducted. Prior to docking, ligand preparation was meticulously performed using Autodock Tools 1.5.6, with geometry optimization utilizing Avogadro software. The interaction was assessed through Gibbs free energy (∆G) scoring, where a more negative ∆G value indicated a stronger binding propensity between the ligand and receptor. The docking results revealed that 22 quercetin derivative compounds exhibited Gibbs energy (∆G) values lower than the original ligand, darunavir. However, 5 compounds deviated from Lipinski's rule, while 17 compounds adhered to Lipinski's criteria. Consequently, these 17 quercetin derivative compounds exhibit promising potential as candidate drugs for HIV-1 protease inhibition.

Abstract

Birds are a good indicator for identifying areas rich in biodiversity, including environmental changes and problems. The reduced number of birds also indicates environmental degradation. Birds play an important role in an ecosystem in maintaining biological balance. These roles include pollinating plants, controlling insect populations and playing a role in the dispersal of plant seeds. In fact, several species of birds are considered key species where their presence in an ecosystem can indirectly influence the existence of other species. Birds need a habitat that acts as a source of food, a place to socialize, reproduce, take shelter, rest and nest. The mangrove area in the Angke-Kapuk Muara Angke Protected Forest is an important bird area or Import Bird Area. The method used is the Visual Encounter Survey (VES). Each species of avifauna found at the observation location was recorded and counted. Bird watching is carried out in the morning at 06.30 – 09.30 WIB. Observations are carried out using a transect route, that is, the observer will walk along the existing observation route. This research will be carried out in the Pantai Indah Kapuk area, namely in the Angke-Kapuk Muara Angke Protected Forest, North Jakarta. This research was conducted in November 2023. This research aims to determine the species composition and diversity of avifauna species at Pantai Indah Kapuk, North Jakarta. Based on the results of research conducted at 11 locations in the Pantai Indah Kapuk area, it was found that there were 62 species of birds from 31 families. The highest number of bird species was found in plot 1, namely 44 species belonging to 24 families and plot 9, namely 36 species belonging to 23 families.

Abstract

Indonesia's biodiversity ranks second largest in the world. This vast potential, if managed well, can be utilized as raw materials for medicines. Currently, 96% of drug raw materials in Indonesia are still imported, making medicines expensive. Therefore, efforts are needed to achieve self-sufficiency in drug raw materials, including researching Indonesian plants with potential as hypercholesterolemia drugs to be used as native raw materials. This study aims to determine the potential of flavonoid compounds in Rhodomyrtus tomentosa fruit as an alternative hypercholesterolemia drug. Six flavonoids were identified: myricetin, quercetin, quercetin 7,4'-diglucoside, dihydromyricetin, kaempferol, and vitexin in R. tomentosa (Karamunting) fruit. The method used was an in silico study. In silico studies are used to screen compounds based on their mechanism of action against target proteins. In this study, myricetin, quercetin, dihydromyricetin, kaempferol, quercetin 7,4'-diglucoside, and vitexin were subjected to molecular docking using Autodock Vina software to determine the affinity and interaction of these six compounds with the HMG-CoA reductase enzyme, which acts as an intermediary in the mevalonate pathway for cholesterol metabolism. Simvastatin, a drug used for hypercholesterolemia treatment, was used as a comparison. The molecular docking results showed that the binding energy values for myricetin, quercetin, dihydromyricetin, kaempferol, quercetin 7,4'-diglucoside, and vitexin were -10.0, -9.4, -9.6, -9.2, -11.4, and -9.9 kcal/mol, respectively. These six flavonoid derivatives from Karamunting fruit have better inhibition scores compared to simvastatin, indicating that these flavonoid derivatives can inhibit cholesterol biosynthesis better than simvastatin and have potential as anticholesterol drugs.

Abstract

Water quality is one of the key indicators of environmental health that impacts aquatic life and human health. Water quality monitoring is important to measure the impact of human activities and ensure water meets quality standards. Conventional methods of manual water sampling face challenges such as distance, safety risks, and long analysis times, making it less effective for rapid monitoring to address environmental pollution. Following Law No. 32 of 2009, the government requires environmental information for environmental management policies. The Ministry of Environment and Forestry encourages using ONLIMO (online monitoring) technology for automated monitoring, with data published through the MoEF's ONLIMO website. This study was conducted to introduce and analyze the efficiency of ONLIMO technology in water pollution control so that policies and actions can be taken quickly and appropriately. Field verification shows physical factors such as indicators of garbage around the Cipinang River water flow, visible murky watercolor, pungent smelling water, dense residential settlements around the Cipinang River water flow, and the number of industries built in the Cipinang River flow indicate that the Cipinang watershed water quality recorded through ONLIMO water quality monitoring sensors and field verification shows a state of mildly polluted conditions. This factor suggests that the ONLIMO KLHK automatic monitoring tool has the effectiveness and efficiency of water quality monitoring because the data entered into the ONLIMO KLHK database through data loggers and field conditions directly show data similarities. Therefore, the ONLIMO KLHK automatic monitoring tool can be an effective early warning system and allows increased efficiency in water pollution control because the data obtained is real-time and by the original water quality conditions at the location.
