An Implementation of XGBoost and Random Forest Algorithm to Estimate Effective Porosity and Permeability on Well log data at Fajar Field, South Sumatera Basin, Indonesia

<p class="Keywords">New approaches and methodologies have been developed to petrophysical analysis from well logs data using machine learning. Through this method, a machine learning algorithm is applied to predict the accuracy of the model on effective porosity (∅e) and permeability (K) which implemented using Random Forest and Xtreme Gradient Boosting (XGBoost) algorithm. The dataset used is obtained from well logs data that have been calculated petrophysical analysis. This study proposes the algorithm which is known to be effective in providing accurate predictions in a short time in estimating effective porosity and permeability. The results of the prediction model is optimized by GridSearchCV (GS), validated by the k-fold cross-validation, and evaluated using R2 score and Root Mean Square Error (RMSE). Model is applied to 5 research wells in Fajar Field of south Sumatra Basin, Indonesia with 4 variations of well training and well testing data split. The best evaluation results obtained with evaluation metrics were up to 0.90 (R2 score) and 0.01 (RMSE) for effective porosity and permeability by Random Forest, while evaluation metrics are 0.90 (R2 score) and under 0.68 (RMSE) for effective porosity and permeability by XGBoost. There is no decrease in accuracy until the last variation so that it can be concluded that these algorithm models can effectively estimate reservoir porosity and permeability in the field and contributed an alternative for the problem of many incomplete and dissimilar well logs data.</p>

Hepcidin levels, markers of iron overload, and liver damage in children with beta-thalassemia major

Background Thalassemia is a hemoglobin synthesis disorder that causes patients to need lifelong blood transfusions, leading to iron overload and alter organ function, including the liver. Hepcidin, produced by the liver, plays a role in iron homeostasis and should be increased in excess iron stores. However, the level decreases in thalassemia due to some factors, such as ineffective erythropoiesis and liver damage. Recent publications revealed that hepcidin could be associated with iron overload and also a marker of liver diseases. Objective To analyse the correlation between hepcidin level, markers of iron overload, and liver damage in beta-thalassemia major. Methods This cross-sectional study included all ?-thalassemia major age 2-18 years admitted to Dr. Mohammad Hoesin Hospital, Palembang, South Sumatera, who underwent blood transfusions from March to August 2022. We measured the level of iron overload markers, hepcidin, liver function test (LFT), and performed liver ultrasonography (USG). Results Of 97 subjects, median hepcidin level was 10.01 ng/mL and 68% of the subjects showed a decrease. The iron overload parameters were evaluated from serum iron levels (P=0.13), ferritin levels (P=0.90), and transferrin saturation (P=0.29) and 24.7% had abnormal liver USG findings. Spearman’s correlation revealed that only direct bilirubin (DB) (r=0.35; P=0.001) and liver USG (r=0.20; P=0.05) had positive correlations with decreased levels of hepcidin. Also, it had 91.7% sensitivity in predicting liver damage from ultrasound. Conclusion The hepcidin level was not significantly associated with iron overload markers.

Morphological Analysis of River Characteristics in Musi Rawas Utara Regency

Effective watershed management requires the efficient collection, storage, and use of runoff water, as well as the recharge of groundwater. This study will employ morphometric analysis to determine the characteristics of the rivers flowing through one of the districts of the Province of South Sumatera, Musi Rawas Utara (Muratara). Using DEM data and GIS software, this study conducted a quantitative-descriptive analysis to obtain quantitative information about the watershed. The acquired numbers are interpreted descriptively to provide a description of the watershed's characteristics and their implications for rivers in Muratara.The eighth-order rivers of Muratara Regency are classified as major rivers. A mean bifurcation ratio (Rb) of 3.98 indicates that geological features have no effect on the typical flat drainage pattern. On average, the drainage density of the watersheds was moderate, but a few locations had a very high drainage density range, indicating their erodibility. The basins of rivers with low circularity and elongation ratios (0.19 and 0.48, respectively) are elongated and have a steep slope. The morphometric research reveals that the Muratara rivers have abundant water resources and are also predicted to experience numerous water-related disasters. Using morphometric knowledge, however, the local government could develop mitigation and planning systems for river management. Future measures must include ensuring that adequate drainage systems are in place and that all construction adheres to the principles of proper land management.

Resources Availability And Income Achievement: A Driving Force For Competitiveness Of Rice Farming Products In Tidal Land, South Sumatera, Indonesia

The land conversion of rice farming could only be prevented by increasing farming competitiveness. The first step is to map the resource availability supporting paddy farming and income achievement. Therefore, this study aimed to analyze resource availability and income achievement to increase paddy business competitiveness. It used a survey method and observed two populations of farmers producing paddy seed and rice in Tanjung Lago and Rambutan Districts, Banyuasin Regency. Simple random sampling was adopted to determine 130 respondents from two populations, each with 65 rice and paddy seed farmers. The findings showed that resource availability supports farming in tidal land, though it is significantly higher for paddy seed than rice farmers. Regarding income achievements, paddy seed farmers also have higher R/C and B/C values than rice farmers. Income for rice farmers mainly comes from corn, rubber, and oil palm, while paddy seed farmers earn from their farming. This implies that the chance of land conversion into plantations and corn farming is greater for rice than for paddy seed farmers. When this happens on a large scale and in the long term, it impacts national rice production. Therefore, improved resource availability and better integration in production could sustainably increase paddy farming production in tidal land.

Distribution of Rain Intensity: Daily Maximum Rainfall Data in The Province of South Sumatera and West Sumatera

The high intensity of rain in May 2024 caused flooding in the Sumatra region, especially Padang City and Palembang City. The region of West Sumatra is also known as the ethalae of disasters with frequent earthquakes, floods, and landslides. In Indonesia, many frequency analyses are conducted using the Gumbel distribution without testing data and clear hydrological reasons. It is feared that this method is considered as a routine way, thus causing the risk of unwanted deviations, resulting in many disasters and errors in the planning of water buildings. This research aims to determine and know the type of distribution that is representative for the maximum daily rainfall frequency in West Sumatra and South Sumatra Provinces as a reference for development and disaster mitigation in the region. The research location is in West Sumatra and South Sumatra. The data used for this study were taken from daily maximum rainfall data from rain stations for 35 to 40 years from 24 rain stations in West Sumatra Province, and 16 rain stations for South Sumatra region. This type of research is development research with the 4D development model (Define, Design, Develop, Disseminate). The development method consists of four different phases: Initial Investigation, Design, Realisation and Development. The data of each station was then organised into two types of data series, namely the annual maximum data series and the annual minimum data series. The results of this data series test are expected to follow one or more types of distributions commonly used in Hydrology and Drainage. The distribution results obtained for the South Sumatra region are Gama-III and LP-III, while for the West Sumatra region the distribution types are Gama-III, LP-III Normal Log and Gembel. The conclusion obtained is that West Sumatra does not have only one type of distribution. For the type of test using the SPSS.22 application, the results obtained are goodness of fit test, parametric test, Chi-Square test, Kolmogorov Smirnov test and Anderson-Darling test and Histrogram (visual) method.

Zero-Burning Policy in Land Preparation: Social Changes and Its Impact on Communities and the Environment

In Indonesia, forest and land fires have become an annual occurrence, with devastating effects. Following major fires in 2015, the government implemented policies restricting the use of fire in land preparation. This policy has affected the livelihoods of traditional farmers who still use fire for land clearing. The research aims to analyze the social changes that have occurred among traditional farmers as a result of the policy to ban burning in land preparation, and to assess its impact. The study was undertaken in Pulang Pisau Regency (Central Kalimantan) and Ogan Komering Ilir Regency (South Sumatera). Findings reveal two types of social transformation processes, namely, changes in agricultural commodities and changes in livelihoods. In general, fire policy restrictions in land preparation improved peatland ecosystems, but has had a detrimental impact on some rural communities living around peatlands. To anticipate these effects, the government promoted no-burn land preparation techniques and initiated a new paddy field construction scheme. However, both were less successful due to local resistance for their unsuitability in the local context.
