Agronomic Evaluation and Yield Potentials of Grafting of Piper nigrum and Piper colobrinum

Foot rot disease (Phytophthora capsica) is Indonesia's primary challenge in cultivating pepper (Piper nigrum). Grafting to another Piper species, Piper coclobrinum, or melada (the local name), is a potential solution to increase resistance to this disease. The use of melada as rootstock has shown promising results during the seedling phase, but it has not been thoroughly evaluated during the production phase. The study was conducted in the pepper grower’s location in Puput and Simpang Katis Villages, Central Bangka, Bangka Belitung Islands Province. The study used kapok (Ceiba petandra) as the standard; plant morphology, leaf area, leaf thickness, and crown diameter for grafted melada and non-grafted pepper were recorded. Harvest variables included panicle length, panicle weight, the number of fruits per panicle, and fruit diameter, measured in three different areas of the canopy: the lower area (0-1 meter above the ground surface), the middle area (1-2 meters above the ground surface), and the top area (more than 2 meters above the ground surface). Physiological variables measured included rates of photosynthesis, stomatal conductance, transpiration rate, intercellular CO2, and CO2 conductance. The study demonstrated that the grafted pepper plants had a larger leaf area than the non-grafted pepper plants; the panicle weight and the number of fruits per panicle were higher. Panicles located in the middle zone of the plant canopy tended to be longer for grafted and non-grafted peppers. Panicle weight, fruit size, and the number of fruits per panicle were generally more significant at the top of the plant canopy. In all parts of the canopy, grafted peppers exhibited larger fruit size, greater panicle weight, and a higher number of fruits per panicle than non-grafted “Nyelungkup” peppers, highlighting the potential of melada as a rootstock for pepper plants.

The purpose of this study is to analyze the correlation between APBN and APBD expenditures on the achievement of connectivity indicators. Secondary data sources were obtained from the Directorate of Budget Implementation, the Sintesa application, the OMSPAN and OMSPAN TKD applications, the Ministry of PUPR, and the BPS of the Bangka Belitung Islands Province. Data analysis uses the Pearson correlation method and qualitative descriptive. The results of the study indicate that APBN expenditure is negatively and very strongly correlated with the length of national roads. In addition, APBN expenditure is positively and very weakly correlated with the length of national roads in stable condition and has a moderate positive correlation with the percentage of national road stability. APBD expenditure is very weakly correlated with the length of provincial roads and is moderately correlated with the length of provincial roads in stable conditions and the percentage of stability. Regency/City APBD expenditure also has a very weak correlation and is negatively directed to the total length of district/city roads in the Bangka Belitung Islands Province and has a moderate correlation with the length of district/city roads in stable condition and the percentage of stability. APBN expenditure has a positive and very strong correlation with the length of regional roads and is positively and strongly correlated with the length of regional roads in stable conditions. APBN spending also has a moderate correlation with the percentage of regional road stability. Based on the relationship analysis using Pearson correlation, it was found that the total length of the road has a strong correlation and has a positive relationship with the ADHK GRDP. The Bangka Belitung Islands Province has a higher road stability than the national road stability and road stability in the Sumatra Region.

PREDICTION OF TIN EXPORTS, POPULATION, POVERTY, AND LABOR FORCE IN THE PROVINCE OF BANGKA BELITUNG ISLANDS

The COVID-19 virus has also caused shocks to the Bangka Belitung Islands Province in various sectors, especially the economy. To overcome this problem, of course the government has prepared responsive policies, both fiscal and monetary policies to prevent post-COVID-19 risks, especially in the economic recession. To prevent a post-COVID-19 economic recession, a prediction or time series forecast is needed on four variables that influence the economic recession, namely the number of tin exports, population, poverty and labor force in the Bangka Belitung Islands Province so that economic growth is maintained. This research aims to predict the four research variables by comparing the Moving Average and Exponential Smoothing methods. This research also uses Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE) as indicators of model accuracy. Based on the results of the accuracy indicators of this model, it was found that the Exponential Smoothing method was better than the Moving Average method.

The Effect of Harvest Time of Sapu-Sapu Leaves (Baeckea frutescens L.) the Yield, Characteristics and Composition of Essential Oils Extached Using Steam-Hydro Distillation Method

The sapu-sapu plant (Baeckea frutescens L.) is widespread in the Bangka Belitung Islands Province, thriving in sandy areas such as beaches and highlands with less fertile soil. This study aimed to determine the optimal harvest time for sapu-sapu leaves to obtain essential oils' highest yield and most desirable characteristics. The research focused on the duck-type sapu-sapu leaves, using five variations of harvest time (coded as A1, A2, A3, A4, and A5, representing leaves harvested at 1, 2, 3, 4, and 5 months of growth, respectively). Essential oil extraction was performed using the steam distillation method. The resulting oils were then analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) to determine their chemical composition. The results showed that sample A1 (1-month growth) produced the highest essential oil yield at 0.74% (w/w). This sample also exhibited the most optimal essential oil characteristics: clear yellow color, characteristic sapu-sapu odor, warm bitter taste, solubility in 96% ethanol at 1:13, specific gravity of 0.8863 g/mL, optical rotation of (+) 10.28°, and refractive index of 1.474. GC-MS analysis revealed that the main compounds in the A1 sample were α-pinene (43.84%), β-pinene (13.56%), and 1,8-cineol (24.26%). The study concluded that while the variation in harvest time of sapu-sapu leaves did not significantly affect the yield, characteristics, or composition of the essential oils, there were slight differences in yield and color. Sample A1, representing the youngest leaves, produced the most optimal results.

Geographically Weighted Regression of Maternal Human Capital on Nutrition of Stunted Toddlers in Tin and Non-Tin Minning Areas

The perspective of maternal human capital on stunted toddler nutrition has a different spatial relationship between tin mining and non-tin mining areas. This study will look at which spatial patterns of maternal human capital influence the nutrition of stunted children under five in tin-mining villages. This study uses primary data on 346 stunted children under five in Bangka Belitung Islands Province, Indonesia. The analysis used geographically weighted regression (GWR) by dividing mining and nonmining areas of Bangka Island and Belitung Island. Maternal human capital that spatially influences the nutrition of stunted toddlers in tin mining and non-mining areas is maternal knowledge about nutritious food. Maternal knowledge of a clean and healthy environment has a negative effect on the nutrition of stunted children under five in the non-mining area of Bangka Island. Maternal education and skills to diversify fish food have an effect on the nutrition of children under five years old in Belitung Island tin mining area. Mothers' skills in diversifying fish food affect the nutrition of stunted children under five in 11 villages in the non-tin-mining area of Belitung Island.

BRAINWASHING SCHEMES AMONG ADOLESCENTS WITH RADICAL POTENTIAL THROUGH STUDENT ORGANIZATIONS IN HIGHER EDUCATION INSTITUTIONS

This study aims to examine the psychological aspects of brainwashing schemes among adolescents with radical potential within student organizations at University X. Adolescence is a period of contradictions, where psychological stability is often fragile, and emotions can be difficult to control. This instability can lead to behaviors that undermine national unity, as evidenced by the growing tendency of youth toward religious radicalism. According to data from Babel Review (2019), based on a 2017 survey by the National Counterterrorism Agency (BNPT), the Bangka Belitung Islands Province ranks fifth nationally in radicalism potential within educational settings. The rise of religious radicalism is often rooted in fragmented religious understanding, misinterpretation of religious texts, and political and economic deprivation, as noted by Azyumardi Azra. This study employs a qualitative methodology to explore the internal cadre training processes within radical organizations, particularly focusing on the brainwashing techniques used in recruiting new members. The findings reveal that these brainwashing practices are systematically and structurally implemented within such organizations, posing a serious threat to social harmony and national unity. This research contributes to a deeper understanding of the radicalization process among adolescents and provides insights into more effective preventive strategies through educational and psychological interventions.

IMPLEMENTATION OF VECTOR AUTOREGRESSIVE (VAR) AND VECTOR ERROR CORRECTION MODEL (VECM) METHOD IN PNEUMONIA PATIENTS WITH WEATHER ELEMENTS IN PANGKALPINANG CITY

The news about Covid-19 is no longer as scary as in previous years. As COVID-19 cases decrease, health protocols are becoming more relaxed, making it easier for the virus to spread. Besides COVID-19, ARI is one of Indonesia's leading causes of death for children under five. Around 20-40% of hospital admissions are children due to ARI, with around 1.6 million deaths due to pneumonia alone in children under five per year. Currently, ARI dominates the diseases most suffered by the people of Bangka Belitung. Based on this, using the VAR and VECM method to analyze pneumonia sufferers in toddlers regarding weather elements in the Pangkalpinang City. The VAR model has a simpler structure with a minimal number of variables where all the variables are endogenous, with the independent variable being the lag. Meanwhile, VECM can be used to model cointegrated and non-stationary time series data. The data used in this research is the number of monthly cases of toddlers suffering from pneumonia and data on climate conditions, namely rainfall, air temperature, air humidity and duration of sunlight during 2019-2021 in Pangkalpinang City. The results of the Granger Causality test show that the pneumonia variables regarding rainfall, temperature, duration of sunlight and humidity only have a one-way causality pattern. The VAR estimation results show that weather elements (rainfall, temperature and duration of sunlight) do not significantly affect pneumonia in the short term. Meanwhile, the VECM estimation results show that in the long-term pattern, humidity variables affect pneumonia. For this reason, it is recommended that the relevant agencies carry out outreach to the public, especially to pneumonia sufferers, to avoid damp weather. Because the lower the humidity value, the greater the potential for pneumonia in Pangkalpinang City, Bangka Belitung Islands Province.
