The coral reef ecosystem in Indonesia boasts the highest biodiversity and serves as the center of the Coral Triangle's diversity. Despite its richness, Indonesia's coral reefs face increasing threats from various factors, primarily anthropogenic. Regular biophysical surveys of coral reef ecosystems are therefore necessary to monitor their current conditions and guide management efforts. This study aimed to assess the condition of coral reefs by examining the percentage of coral cover in the Gili Balu Marine Conservation Area, Sumbawa NTB. The research was conducted in January, 2022, using the Point Intercept Transect (PIT) method at 10 observation points. The transects measured 50 meters in length and were repeated three times at each location. The results indicated that the coral reefs were in good condition at the South Belang Island Station (57%) and West Pasareang Island (69.67%), according to Kepmen LH No. 4/2001. However, moderately damaged reefs were observed at North Belang Station (38%), Kenawa Island (30%), East Belang Island (30%), and Mandiki Island (28.67%). Coral reefs classified as severely damaged were found at Southwest Namo Island Station (17.33%), North Pasareang (16.67%), South Kalong (11%), and North Namo (9.67%). Overall, the dominant condition of coral reefs in the Gili Balu Conservation Area was categorized as moderately to severely damaged. Conservation efforts, including protection in areas with good conditions and rehabilitation in damaged areas, are recommended as follow-up actions to support coral reef sustainability in Gili Balu.

Published: January 2025

Knowledge of competition at the plant community level is useful as a basis for studying competition aspects in a broader scope. One of the simplest things is understory competition due to differences in tree canopy cover. The purpose of this study was to describe the role of shade trees on competition and understory community structure. A total of 6 plots measuring 1 m × 1 m were made under stands of Ficus calosa, Ficus benjamina, and Terminalia catappa trees (Location 1 and Location 2), while 3 other plots of the same size were made under stands of Hevea brasiliensis trees (Location 3). Structure, composition and diversity were studied using vegetation analysis techniques. The results showed that Locations 1 and 2 were dominated by Phytolacca americana and Asystasia gangetica, while Location 3 was dominated by Axonopus compressus and Asystasia gangetica. Further analysis showed outlier data from the three locations indicated an abundant number of individuals of Phytolacca americana and Asystasia gangetica, and Axonopus compressus. All of these dominant species are invasive. Regression analysis shows that the projection of increasing canopy cover causes an increase in the density of certain species, but not significantly (P >0.05). The higher the dominance index, the smaller the species diversity value. Therefore, it can be concluded that a dominant species is usually competitive and can change the distribution structure and diversity of understory plants under different tree canopies.

Published: January 2025

Mycobacterium leprae is a causative agent of leprosy, a chronic granulomatous infection that primarily affects the skin and the peripheral nerves. Musculoskeletal involvement, including inflammatory arthritis, is quite common despite being under recognized. Leprosy presents protean manifestations, making it a great mimicker. Herein, we report a case of a 41-year-old Indonesian who resided in Malaysia for the past 20 years and presented with chronic joint pain and swelling of hands for a year, along with gradual facial swelling and numbness in the toes. Retrospectively, the patient noticed an erythematous skin lesion over the trunk and lower limbs 6 months before these symptoms, which did not improve with standard treatment for allergic reactions. These spectral manifestations and the subtle signs of leprosy led to a diagnostic delay of more than a year. In this study, we aim to enhance clinical awareness among primary care providers about recognizing, classifying, and appropriately treating the disease to prevent life-long deformity and disability.

Published: January 2025

Côte d'Ivoire's forests are a reservoir of biodiversity. Indeed, they offer a diverse ecosystem service. However, they are subject to strong anthropogenic pressures, which have resulted in the disappearance of several plant species. This was the case of Mansonia altissima, a species renowned for the quality of its wood. Given the importance of this species, there is an urgent need to focus on its conservation. It is in this context that this study aims to improve seed multiplication and the growth of M. altissima seedlings with a view to using them in reforestation. To achieve this, three pretreatments were applied to the seeds. These were the control (T0), shelled and unsoaked winged fruit (T1) and winged fruit soaked in cold water for 48 hours and then shelled (T2). Data collected using a data collection form were subjected to statistical analysis. Results showed that T2 treatment recorded the best germination rate (83%). In terms of seedling growth, the pretreatments had a significant effect on seedling diameter (P > 0.05). As for height, which averaged around 8 cm, and number of leaves, which averaged 6 per individual for each pretreatment, no significant effect was observed. However, for a multiplication of the species, the pretreatment (T2) where the winged fruits are soaked in ordinary water for 48 h and then shelled is recommended.

Globally, COVID‐19 pandemic imposed unparalleled challenges for food, agriculture and industries that led to disruptions in supply chains and demand dynamics. In Nigeria, this period showcased people’s adaptability, resilience and innovativiness and underscored the importance of diversifying supply chains. This paper reviews the importance of Lactic Acid Bacteria (LAB) in food, agriculture and industry specifically highlighting their role as starter cultures for fermented foods. Lactic acid bacteria belong to a group of gram positive, beneficial bacteria, which produce lactic acid as their primary fermentation product. They have always been used for food and dairy products fermentation and focus has been on their applications. Fermented foods are produced through fermentation of certain sugars, especially lactose by LAB. The end products of the breakdown include bacteriocins which are bio-protective agents of industrial importance. Of particular agricultural and food importance is probiotic application of some LAB. Probiotics are living microbial feed supplement that beneficially affects the host by improving its intestinal microbial balance. The Bacteriostatic and bactericidal potentials of certain metabolites of LAB origins were elucidated. These polypeptides synthesized by the LAB ribosome have been reported to be antagonistic to several bacteria. The nutritional benefits and safety consideration of LAB were also emphasized. Limitations to the use of LAB and their future prospect were briefly highlighted. Given the potential applications of LAB to the Nigerian food, agriculture and industries, it is recommended that starter cultures with outstanding traits be further developed and adapted to local needs.

Authors: Toochukwu Juliet Mgbole
Published: January 2025

Neural network systems have become the gold provocative standard in blood-based biomarker analysis for metastatic disease diagnosis, providing higher sensitivity and specificity for early cancer detection. The lexical method also showed that recent developments in artificial intelligence and machine learning technologies allow for the complex interpretation of various types of biomarkers, such as circulating tumor cells, cell-free DNA, microRNAs, and proteins. Many biochemical patterns of biomarkers could be easily handled through sophisticated algorithms and depending on these active approaches in diagnosing metastatic outcomes more accurately at earlier stages. Literature analysis involved a targeted selection of scientific peer-reviewed articles dedicated to neural network utilization in blood-based biomarker screening for cancer. Doing a systematic evaluation critically assessed methodologies associated with artificial intelligence, types of biomarkers, methods of detecting biomarkers, and clinical validation strategies. Filtering was done based on several factors including the identification of new architectures for neural networks, new biomarker analysis methods, and clinical applications primarily focusing on the early detection of metastatic diseases. Analysis of reviewed studies showed a high diagnostic accuracy when neural network systems are used for biomarker analysis. Volumes in Cancer Computational Biology Vol reported that the machine learning models have achieved different sensitivity rates of over 90% including the ability to detect early-stage metastatic disease. The use of several categories of biomarkers and application-improved neural networks for their evaluation showed that the combined use of markers yields better diagnostic results than using single biomarkers. Neural network systems have significant potential to transform metastatic disease diagnosis using circulating biomarker detection. Using sophisticated computational models biomarker patterns are analyzed in detail and the diagnosis is made earlier, thus contributing to better treatment outcomes. Some complexities that are potential barriers include enforcing analysis protocols as standards, correcting and calibrating, and embracing routine technological practice. High-end artificial neural networks are the new frontier in blood-based biomarker analysis of metastatic disease diagnosis.

Background: Sleep is vital for brain development, body healing, production of repair molecules, and long-term memory formation. Poor sleep quality in adolescents can lead to psychological problems such as depression, stress, and anxiety, which can negatively affect daily life and academic performance. Addressing these issues is essential to ensure optimal sleep quality for optimal brain function.

Aim: The purpose of this study was to investigate the relationship between sleep patterns and mental health in adolescents.

Method: A cross-sectional study was conducted, measuring sleep quality with PSQI and stress, anxiety, and depression with the DASS-Y questionnaire among 350 students from different middle colleges and private schools.

Results: A study found that 13-15 year old have a higher prevalence of poor sleep (83%) while 16-18 year old have more balanced sleep (51% poor, 49% good). Nearly half of the 350 participants experienced poor sleep quality, with stress, anxiety, and depression being the most common. The study found a significant relationship between sleep quality and (mental health).

Conclusion: Sleep deprivation increases mental illness vulnerability, highlighting the need for healthy sleep habits. Clinical pharmacists collaborate with medical professionals to improve adolescents' physical and psychological health through techniques and counseling, promoting good sleep habits.

Abad pertengahan menjadi masa kemajuan peradaban Islam khususnya dalam bidang ilmu pengetahuan, namun pada akhir abad pertengahan peradaban Islam menemui kemunduran karena modernitas di Barat. Sehingga membuat Muhammad Abed Al-Jabiri sebagai cendekiawan muslim melakukan kritik terhadap epistemologi nalar Arab dalam upaya meraih kebangkitan kembali peradaban Islam. Al-Jabiri melakukan analisis historis terhadap 3 epistemologi nalar Arab yang menjadi kerangka pengetahuan Arab-Islam tradisional. Penelitian ini menggunakan pendekatan analisis deskriptif serta analisis kritis dan menggunakan metode kajian kepustakaan atau library research. Dari tulisan ini ditemukan bahwa al-Jabiri memberikan tawaran untuk membangun nalar Arab berbasis burhānī untuk mencapai kemajuan peradaban Islam.

Published: January 2025

This study applies a rolling window cross-validation to evaluate the multi-step forecasts instead of using the traditional single split for Hang Sheng Index (HSI) forecasting. The forecasting methods discussed in this study are Holt's Exponential Smoothing and auto ARIMA, chosen because of their ability to model trend data as in the daily HSI. This research aims to evaluate up to five step forecast values obtained by the two forecasting methods built in the training data with rolling window cross-validation. In the experiment, each of the 21 auto ARIMA and Holt's models was constructed from 84 observations (as in-sample data) obtained from the rolling window cross-validation. The one to five step forecast values of daily HSI are then calculated using those models, and the accuracy of each forecast value is evaluated based on Mean Absolute Percentage Error (MAPE). The results show that the Auto ARIMA model produces a lower MAPE value than Holt's model, namely 2.9196%, 4.6553%, 6.4012%, 8.3083%, and 10.3781%, respectively, for one to five steps ahead. Therefore, auto ARIMA is more recommended for forecasting HSI values up to five steps ahead than Holt's method.

Random forest algorithm allows for building better CART models. However, the disadvantage of this method is often underfitting, especially for small node sizes. Therefore, the double random forest method was developed to overcome this problem. The research was conducted by utilising Education Management Information System (EMIS) data, which is related to the incidence of school dropout. The data used consists of 2 data, namely MTs and MA dropout data. The initial testing procedure was carried out using the random forest algorithm for each data set, then the data was evaluated using the double random forest method. From this study, the underfitting case can be overcome well using the double random forest algorithm, while in the fit case, the difference in the goodness-of-fit value of the model is relatively the same. The results obtained show that MTs prioritise school quality more than MA, although family factors are more important at the MA level. Although the total number of factors used is basically the same, it should be noted that the two school levels have different relevance variables. It should be noted that no forecasting was done in this study given that the methodology used two different types of data.

One of the concerns of both developed and developing countries, as well as in a region, is the amount of inflation that occurs. Inflation is a serious problem. Inflation is a macroeconomic variable that affects people's welfare and is defined as a complex phenomenon resulting from general and continuous price increases. This research aims to analyze the volatility and projected value of the inflation rate, especially in Pangkalpinang City, using the Autoregressive Conditional Heteroskedasticity (ARCH) and Generalized Autoregressive Conditional Heteroskedasticity (GARCH) models. This research uses time series data on inflation rate of Pangkalpinang, Bangka Belitung Island Province from January 2014 to May 2024. This data was obtained through publications from the Central Statistics Agency of Bangka Beliltung Islands Province. The ARCH model is used to handle heteroscedasticity in data, while the GARCH model is a development of the ARCH model and serves as a generalization of the volatility model. This research shows that the predicted inflation rate in Pangkalpinang City from June 2024 to November 2024 tends to decrease with a MAPE prediction accuracy level of 200.04%. The high MAPE value is caused by actual data moving toward 0.
