Abstract

Coral reefs are one of the coastal ecosystems that have an important role as a place to look for food, shelter, and breeding grounds for other biota. Corals are invertebrates that are included in the phylum Coelenterata (hollow animal) or Cnidaria. Whereas coral reefs are a collection of millions of polyps. Natural phenomena and various anthropogenic activities threaten the health and existence of coral reefs in the waters of Bunaken National Park, Popareng Village. The purpose of this study is to determine the condition of coral reefs in the waters of Bunaken National Park, Popareng Village. CPCe (Coral Points Count with Excel extension) is used to observe or monitor reef ecosystems. The photo that will be taken using the Underwater Photo Transect (UPT) method from 3 observation stations in Popareng’s Waters will be used as this research database. The photos consist of 50 slides for each station. Photos were taken to represent Popareng’s waters. Each photo was processed in the CPCe by using 30 random points. The condition of the coral reefs in Popareng was moderate. The results of coral reef health conditions at three stations in Popareng reveal poor (21.67%) in station 1; good (54.53%) in station 2; and moderate (32.37%) in station 3.

Abstract

Simpur (Dillenia sp.) is a plant that can be used as traditional antibacterial medicine. This study aims to determine the inhibitory activity of Staphylococcus aureus bacteria when exposed to a concentration of methanol extract from Simpur leaves (Dillenia sp.). This study utilized a completely randomized design with five concentration levels of Dillenia sp. specifically, the study included a control group and methanol extracts of Simpur leaves at concentrations of 5%, 10%, 15%, and 20%. The methods used included total plate count, hemocytometer, and UV-Vis spectrophotometry, which were then analyzed using ANOVA (Analysis of Variance). The results showed that the greatest inhibition occurred in the methanol extract of Simpur leaves (Dillenia sp.) at a concentration of 20%, there was a decrease in the number of colonies ranging from 90% to 94%, while the decrease in the number of cells ranged from 17% to 18%. The lowest inhibition was found in the methanol extract of Simpur leaves (Dillenia sp.) with a concentration of 10%, the proportion of decreasing the number of colonies ranged from 63% to 70%, while the proportion of decreasing the number of cells ranged from 6% to 7%. The highest optical density (OD) value at a 20% concentration ranged from 0.482 to 0.547, while the lowest value at a 5% concentration ranged from 0.127 to 0.131. The conclusion of this study is that the methanol extract of Simpur leaves (Dillenia sp.) Bacteriostatic antibiotics only inhibit bacterial growth and cannot kill bacteria.

Abstract

The agrosilvopastura system is one part of an efficient agroforestry system to be applied in integrated landscape management. The community in Taratara Village, West Tomohon Sub-district, North Sulawesi Province has a majority of people who work as farmers. Some of the people of Taratara Village who work as farmers also raise livestock on the same plot of land with various crops. This indicates that the community group applies the agrosilvopastura system in their landscape management. This study aims to assess the pattern of agrosilvopastura application in Taratara Village. The research method used was a survey method by means of interviews using a questionnaire as a guide and field observations. The survey results show that, in Taratara Village there are as many as 5 farmers who apply agrosilvopastura patterns. The results showed that the agrosilvopastura pattern in Taratara Village combines the cultivation of forestry crops and agricultural crops together with the raising of livestock (pigs, ducks, chickens, cows) on the same land. Livestock are raised with various methods and feeds that are adapted to the type of livestock. Woody crops are planted randomly and regularly, and food crops are also planted regularly and regularly among woody crops. Farmers who apply the agrosilvopastura pattern in Taratara Village choose this pattern because of its advantages, namely 1) getting more optimal results with the presence of trees, food crops and livestock on the same land, 2) parts of cultivated plants that are not consumed or poor harvests can be used as animal food, 3) more efficient land utilization, 4) the acquisition of products (harvestable products) is more diverse, 5) certain livestock raised can be utilized for their energy, 6) improving soil fertility.

Abstract

One of the important behaviors of stingless bees is hygienic behavior, which includes cleaning the nest from dirt, food scraps, and dead insect carcasses to keep the colony healthy and disease-free. The goal of this study was to determine the type and quantity of waste produced by H. itama in the nest, as well as the time spent by worker bees removing waste from the nest. The research method employed was direct observation and quantitative measurement of three active H. itama colonies. The findings revealed that the trash generated contained carcasses, feces, and food scraps. Feces and food scraps accounted for 89%, with carcasses accounting for 11%. The activity of flinging waste out of the nest decreased during the day due to H. itama's high movement in and out of the nest in search of food, as well as high ambient temperatures. The busiest times for garbage disposal were in the morning (09.10 - 11.10 WIB) and afternoon (13.10 - 16.10 WIB). A clean nest with minimal waste suggests a healthy H. itama colony with good hygiene behaviors. In contrast, a messy nest with much excrement indicates an unhealthy H. itama colony with poor hygiene.

Abstract

Kepiting bakau memiliki potensi sebagai komoditas perikanan utama yang dapat mendukung mata pencaharian para nelayan. Namun, tingginya permintaan pasar dapat mendorong nelayan untuk mengeksploitasi sumber daya ini secara berlebihan, yang mengakibatkan penurunan volume tangkapan dan penurunan rata-rata ukuran kepiting yang tertangkap. Kelimpahan kepiting bakau sangat bergantung pada kesehatan hutan mangrove, dan setiap degradasi habitat ini dapat mempengaruhi populasi kepiting secara signifikan. Penelitian ini bertujuan untuk memperkirakan kelimpahan kepiting bakau dan menganalisis rasio jantan dan betina kepiting. Penelitian dilakukan pada bulan Februari 2024 dengan menggunakan metode purposive sampling. Observasi dimulai dengan menetapkan plot berukuran 100x20 meter, di mana kepiting ditangkap menggunakan perangkap yang disebut rakang. Hasil penelitian menunjukkan bahwa Stasiun Satu memiliki kelimpahan kepiting tertinggi, dengan 18 individu teridentifikasi. Stasiun Dua memiliki kelimpahan sebanyak 4 individu, dan Stasiun Tiga memiliki 3 individu. Rasio kepiting jantan dan betina di Stasiun Satu adalah 67% jantan dan 33% betina, sedangkan di Stasiun Dua rasio jantan terhadap betina adalah 75% dan 25%, dan di Stasiun Tiga rasio jantan terhadap betina adalah 67% dan 33%. Lebar kerapas berkisar antara 12,63 cm hingga 13,89 cm, dengan bobot kepiting bervariasi antara 344,33 gram dan 405,32 gram.

Abstract

Sumatra Island, especially North Sumatra Province, is a habitat for various freshwater fish species, including Trichopsis vittata. This study aimed to assess the sex ratio and size class distribution of T. vittata in three different locations: Tebing Linggahara Village, Bulungihit Village, and Silau Rakyat Village. Fish samples were caught using a serving hood, and total length and weight were measured. The results showed that the sex ratio of T. vittata was 1:1, indicating a balance of males and females in the population. The size distribution of fish was dominated by the rather large (46.27-52.27 mm) and small (34.25-40.25 mm) classes, indicating a diverse population growth. This condition shows that the recruitment process is still running well in nature. This study is expected to be the basis for the management and conservation of T. vittata in North Sumatra waters. It is recommended that further research be conducted on the ecological aspects of the habitat to support the conservation of this species

Abstract

The prevalence of hypertension in Indonesia continues to increase from year to year, especially in the city of Manado. The Central Statistics Agency of Manado City shows that hypertension is the disease with the highest prevalence in Manado City with a total of 27,604 cases in 2020. Hypertension risk factors are divided into 2 major parts, namely unmodified risk factors and modified risk factors. Non-modifiable risk factors such as age over 65 years, family history, and comorbidities such as diabetes mellitus (DM) or kidney disease. Risk factors that can be changed include an unhealthy diet (excessive salt consumption, a diet high in saturated fats and trans fats, low intake of fruits and vegetables), lack of physical activity, tobacco and alcohol consumption, and being overweight or obese. The purpose of this study is to analyze the correlation between age and smoking habits and the incidence of hypertension in the community in the city of Manado. This study is an observational research with a cross-sectional approach. The data was taken in Manado City. Data collection will be carried out in June 2024. Data collection was carried out through interviews using questionnaires. The data were analyzed using the square khi test. The results showed that the most distributed respondents were aged 50 years and over (63.3%), did not smoke (60.0%) and had hypertension (70.0%). The results of bivariate analysis obtained p values of 0.803 (age correlation with hypertension) and 0.328 (correlation between smoking habits and hypertension). This value suggests that there is no significant correlation between age and smoking habits and the incidence of hypertension. It can be concluded that age and smoking are not correlated to the incidence of hypertension in the people of Manado city.

Abstract

Mpox is a zoonotic disease caused by Monkeypox virus (MPXV), with a surge in cases posing a major challenge due to the unavailability of specific antivirals. Indonesia's biodiversity offers great opportunities for the exploration of bioactive compounds from natural materials as therapeutic alternatives, especially by targeting the D13 protein, which is an essential structural protein in MPXV. This study aims to evaluate the interaction and affinity of molecular tethering of bioactive compounds to D13 protein and analyse the physicochemical, pharmacokinetic and toxicity profiles of the compounds. The research was conducted using molecular tethering method using Gnina software on Google Colab platform. Antiviral activity prediction was performed using PASS Online, followed by Lipinski's Rule of Five (RO5) evaluation and pharmacokinetic and toxicity analysis using SwissADME and pkCSM. The results showed that the tested bioactive compounds had good potential antiviral activity and fulfilled the RO5 criteria. Pharmacokinetic and toxicity analyses indicated good pharmacokinetic profiles but poor metabolic profiles, with predicted low toxicity levels, supporting the feasibility of these compounds to be further developed as therapeutic candidates. In addition, the bioactive compound showed the ability to interact with D13 protein with the best affinity tethering value of myricetin with a free binding energy (ΔG) value of -8.37 kcal/mol, making it a potential candidate as an antiviral for Mpox.
