ANALISIS FAKTOR - FAKTOR YANG MEMPENGARUHI VOLUME EKSPOR KAKAO DI INDONESIA 2015 – 2019

Cocoa is one of the plantation commodities that has an important role in economic activities in Indonesia. Cocoa is also one of Indonesia's export commodities which is quite important as a foreign exchange earner besides oil and gas. Indonesia is the world's third largest cocoa producer and exporter after Ghana and Ivory Coast. The development of cocoa exports in 2015-2019 has a fairly volatile pattern. In 2015 the total export volume of cocoa was 105.15 thousand tons and in 2017 it increased by 270.17 thousand tons. The results of this study indicate that partially the US Dollar exchange rate variable has a negative and significant effect on the volume of cocoa exports in Indonesia 2015-2019. The price variable has a positive and significant effect on the volume of cocoa exports in Indonesia 2015-2019 and the variable amount of cocoa production has no effect on the volume of cocoa exports in Indonesia 2015-2019. Simultaneously the US Dollar exchange rate, price and amount of cocoa production have a significant effect on the volume of cocoa exports in Indonesia 2015-2019 and the variable amount of cocoa production has no effect on the volume of cocoa exports in Indonesia 2015-2019. This analysis shows that the variable that has the dominant influence on the volume of cocoa exports in Indonesia from 2015-2019 is the price variable.

Novel solution structures localized in fractional integrable coupled nonlinear Schrödinger equations

Fractional calculus highlights its importance and has been expanded to many fields. This paper focuses on fractional integrable systems and their novel structural solutions to comply with the forefront development of nonlinear waves. Specifically, a system of fractional integrable coupled nonlinear Schrödinger (CNLS) equations are first derived from the associated linear spectral problem equipped with space-time conformable fractional derivatives of different orders. Then, by extending Darboux transformation (DT) and its generalized version to the derived fractional CNLS equations, we obtained fractional single-soliton solutions and double- and triple-semirational solutions that obey the dual power laws of independent variables. Under the dominant influences of space-time fractional orders, some novel solution structures are finally revealed based on the obtained solutions. In terms of characteristics, these spatial structures exhibit inclination, symmetry and spikes. Observing from the perspective of propagation, some of these obtained solutions have time-varying velocities and widths. From the perspective of spatiotemporal structures, some solutions form collapsed quadrangular pyramids. All of these novel solution structures cannot be supported by the integer-order CNLS equations.

Disaster risk reduction in elementary schools in flood-prone areas (Case: disaster risk reduction in Grogol flood-prone areas, Indonesia)

Floods disaster have caused much damage and disruption to the continuity of education. Therefore, disaster risk reduction efforts must be carried out, especially in the school environment. This study aims to analyze how Disaster Risk Reduction efforts are conducted in elementary schools in the Grogol flood-prone area, Indonesia. This research is quantitative research with a survey design. Data collection is carried out using questionnaires and documentation. The instrument used is a closed questionnaire with indicators of Disaster Risk Reduction, including knowledge and attitudes, school policies, preparedness planning, and resource mobility. The population in this study were five elementary schools located in flood-prone areas of Grogol, Indonesia, including SDN Madegondo 1, SDN Madegondo 3, SDN Pandean 1, SDN Kadokan 1, and SDN Pandean 2. Respondents in this study were 40 teaching staff who consisted of principals, homeroom teachers, and teachers from each elementary school. The data analysis technique used is descriptive statistical data analysis. The results of this study were shocking; even though floods overflow the river almost every year, all schools in the flood-prone areas were classified as in the low class in implementing Disaster Risk Reduction for flood disasters. One factor that has a dominant influence was the absence of an official policy from the government that officially regulates the implementation of Disaster Risk Reduction for flood disasters in the region. The results of this study are expected to be used as a basis for implementing disaster risk reduction by elementary schools against floods.

Variations of skin thermal diffusivity on different skin regions.

Skin thermal diffusivity plays a crucial role in various applications, including laser therapy and cryogenic skin cooling.This study investigates the correlation between skin thermal diffusivity and two important skin parameters, melanin content and erythema, in a cohort of 102 participants. An in-house developed device based on transient temperature measurement was used to assess thermal diffusivity at different body locations. Melanin content and erythema were measured using a colorimeter. Statistical analysis was performed to examine potential correlations. The results showed that the measured thermal diffusivity values were consistent with previous reports, with variations observed among subjects. No significant correlation was found between thermal diffusivity and melanin content or erythema. This suggests that other factors, such as skin hydration or epidermis thickness, may have a more dominant influence on skin thermal properties. This research provides valuable insights into the complex interplay between skin thermal properties and physiological parameters, with potential implications for cosmetic and clinical dermatology applications.

Referent data for investigations of upper limb accelerometry: harmonized data from three cohorts of typically-developing children.

The rise of wearable sensing technology shows promise for addressing the challenges of measuring motor behavior in pediatric populations. The current pediatric wearable sensing literature is highly variable with respect to the number of sensors used, sensor placement, wearing time, and how data extracted from the sensors are analyzed. Many studies derive conceptually similar variables via different calculation methods, making it hard to compare across studies and clinical populations. In hopes of moving the field forward, this report provides referent upper limb wearable sensor data from accelerometers on 25 variables in typically-developing children, ages 3-17 years. This is a secondary analysis of data from three pediatric cohorts of children 3-17 years of age. Participants (n = 222) in the cohorts wore bilateral wrist accelerometers for 2-4 days for a total of 622 recording days. Accelerometer data were reprocessed to compute 25 variables that quantified upper limb movement duration, intensity, symmetry, and complexity. Analyses examined the influence of hand dominance, age, gender, reliability, day-to-day stability, and the relationships between variables. The majority of variables were similar on the dominant and non-dominant sides, declined slightly with age, and were not different between boys and girls. ICC values were moderate to excellent. Variation within individuals across days generally ranged from 3% to 32%. A web-based R shiny object is available for data viewing. With the use of wearable movement sensors increasing rapidly, these data provide key, referent information for researchers as they design studies, and analyze and interpret data from neurodevelopmental and other pediatric clinical populations. These data may be of particularly high value for pediatric rare diseases.

Algae development in rivers with artificially constructed weirs: Dominant influence of discharge over temperature

Algal blooms contribute to water quality degradation, unpleasant odors, taste issues, and the presence of harmful substances in artificially constructed weirs. Mitigating these adverse effects through effective algal bloom management requires identifying the contributing factors and predicting algal concentrations. This study focused on the upstream region of the Seungchon Weir in Korea, which is characterized by elevated levels of total nitrogen and phosphorus due to a significant influx of water from a sewage treatment plant. We employed four distinct machine learning models to predict chlorophyll-a (Chl-a) concentrations and identified the influential variables linked to local algal bloom events. The gradient boosting model enabled an in-depth exploration of the intricate relationships between algal occurrence and water quality parameters, enabling accurate identification of the causal factors. The models identified the discharge flow rate (D-Flow) and water temperature as the primary determinants of Chl-a levels, with feature importance values of 0.236 and 0.212, respectively. Enhanced model precision was achieved by utilizing daily average D-Flow values, with model accuracy and significance of the D-Flow amplifying as the temporal span of daily averaging increased. Elevated Chl-a concentrations correlated with diminished D-Flow and temperature, highlighting the pivotal role of D-Flow in regulating Chl-a concentration. This trend can be attributed to the constrained discharge of the Seungchon Weir during winter. Calculating the requisite D-Flow to maintain a desirable Chl-a concentration of up to 20 mg/m3 across varying temperatures revealed an escalating demand for D-Flow with rising temperatures. Specific D-Flow ranges, corresponding to each season and temperature condition, were identified as particularly influential on Chl-a concentration. Thus, optimizing Chl-a reduction can be achieved by strategically increasing D-Flow within these specified ranges for each season and temperature variation. This study highlights the importance of maintaining sufficient D-Flow levels to mitigate algal proliferation within river systems featuring weirs.

Response of soil erosion to vegetation and terrace changes in a small watershed on the Loess Plateau over the past 85 years

Land use on the Chinese Loess Plateau has undergone dramatic changes over the past few decades. The implementation of a series of soil and water conservation measures has significantly altered the soil erosion, transportation, and deposition processes on the Loess Plateau. To effectively address and mitigate soil erosion, it is crucial to accurately quantify the soil loss rate and analyze the contributions of soil and water conservation measures over the past several decades. In this study, the Zhifanggou watershed, located in the hilly area of the Chinese Loess Plateau, is utilized as an illustrative example. Using historical data, remote sensing imagery, and on-site data of soil, vegetation, and soil conservation measures, we assessed the soil loss rates from 1938 to 2022 based on long-term land use changes, utilizing the Chinese Soil Loss Equation (CSLE) model. Furthermore, we employed a quantitative evaluation to assess the impacts of vegetation change and terrace construction on soil erosion. The findings of our study reveal significant transformations in land use. Farmland experienced an initial increase followed by a subsequent decline, while the opposite pattern was observed for forest land. The simulated soil loss rate for the entire watershed exhibited an upward trend, rising from 34.86 t·ha−1·yr−1 in 1938 to 104.11 t·ha−1·yr−1 in 1958, before declining to 56.98 t·ha−1·yr−1 in 1999 and reaching 5.87 t·ha−1·yr−1 in 2022. Attribution analysis showed that vegetation change exerted a dominant influence on recent soil erosion dynamics, accounting for 86.10 % of the total contribution in 2022, while terraces contributed 13.90 %. These findings clarify long-term soil erosion mechanisms and provide guidance for watershed soil and water conservation management.

A Mechanistic Model and Experiments on Bedrock Incision and Channelization by Rockfall

AbstractRockfall and rock avalanches are common in steep terrain on Earth and potentially on other planetary bodies such as the Moon and Mars. Since impacting rocks can damage exposed bedrock as they roll and bounce downhill, rockfall might be an important erosive agent in steep landscapes, even in the absence of water. We developed a new theory for rockfall‐driven bedrock abrasion using the ballistic trajectories of rocks transported under gravity. We calibrated this theory using laboratory experiments of rockfall over an inclined bedrock simulant. Both the experiments and the model demonstrate that bedrock hillslopes can be abraded by dry rockfall, even at gradients below the angle of repose, depending on the bedrock roughness. Feedback between abrasion and topographic steering of rockfall can produce channel‐like forms, such as bedrock chutes, in the absence of water. Particle size has a dominant influence on abrasion rates and runout distances, while the hillslope angle has a comparatively minor influence. Rockfall transport is sensitive to bedrock roughness; terrain with high friction angles can trap rocks creating patches of rock cover that affect subsequent rockfall pathways. Our results suggest that dry rockfall can play an important role in eroding and channelizing steep, rocky terrain on Earth and other planets, such as crater degradation on the Moon and Mars.

Ensemble projections of climate and streamflow in a typical basin of semi-arid steppes in Mongolian Plateau of 2021–2100

The Kherlen River is the main water source for Hulun Lake, the largest lake in northern China. Due to reduced inflow from the Kherlen River, Hulun Lake experienced rapid shrinkage at the beginning of the 21st century, posing a serious threat to the ecological security of northern China. However, there is still a significant lack of projections regarding future climate change and its hydrological response in the Kherlen River basin. This study analyzed the projected climate and streamflow changes in the Kherlen River basin, a vital yet vulnerable international semi-arid steppes type basin. A combination of multi-model ensemble projection techniques, and the soil and water assessment tool (SWAT) model was employed to examine the spatio‒temporal changes in precipitation, temperature, streamflow, and the associated uncertainties in the basin. The temperature (an increase of 1.84–6.42 °C) and the precipitation (an increase of 15.0–46.0 mm) of Kherlen River basin are projected to increase by 2100, leading to a rise in streamflow (1.08–4.78 m3 s−1). The upstream of the Kherlen River exhibits remarkable increasing trends in precipitation, which has a dominant influence on streamflow of Kherlen River. Noteworthy increases in streamflow are observed in April, August, September, and October compared to the reference period (1971–2000). These findings suggest a partial alleviation of water scarcity in the Kherlen River, but also an increased likelihood of hydrological extreme events. The projected temperature increase in the Kherlen River basin exhibits the smallest uncertainty, while more pronounced uncertainties are found in precipitation and streamflow. The spread among the results of CMIP6 models is greater than that of CMIP5 models, with lower signal-to-noise ratio (SNR) values for temperature, precipitation, and streamflow.

Optimizing anti-freezing agent on the properties of Portland cement-calcium sulphoaluminate cement system based on Taguchi-GRA method

The investigate of novel cementitious system suitable for negative temperature concreting was the key way to solve the high energy consumption of traditional winter construction. In this study, the matching effects of anti-freezing agents (CaCl2, NaNO2 and Li2CO3) on the Portland cement-calcium sulphoaluminate cement blended system (PC-CSA system) based on Taguchi-Grey Relational Analysis (Taguchi-GRA method) were studied. The setting time, compressive strength and freezing point were tested, and the hydration products, pore structure and morphology were also analyzed to reveal the mechanism. The results showed that CaCl2 was the main parameter influencing the initial and final setting time. Whether at the early stage of continuous negative temperature curing, or from negative to positive temperature curing, CaCl2 had a dominant influence on the compressive strength of PC-CSA system, which promoted the increase of the early hydration products, resulting in the rapid formation of a network structure. At the later stage of continuous negative temperature curing, the influential parameter changed to NaNO2. The basic condition for hydration was provided due to the lowering of the freezing point of the liquid phase by NaNO2. The presence of Li2CO3 enhanced the promoting effect of CaCl2 on early strength. The optimal parameter combination for PC-CSA system was 1.0 % CaCl2, 2.0 % NaNO2 and 0.4 % Li2CO3 based on Taguchi-GRA method.

The 1948 Soviet-Yugoslav Conflict in the Public Discourse of Montenegro

The article analyzes Montenegrin public discourse in the first years after the Second World War in the context of the political conflict between the Soviet Union and Yugoslavia in 1948. The research has been based on archival material, daily press, and texts in literary journals, and is focused on the change of public discourse towards the ussr, conditioned by the political and ideological conflict between Yugoslavia and the ussr. The historical and semantic-pragmatic analysis of the text, as well as the analysis of lexical cohesion and taxonomy, indicate all changes in public discourse that result from the political conflict between the two countries. The critical analysis of public discourse points to the justification of the initial research hypothesis that political processes had a dominant influence on the formation of postwar public discourse in Montenegro.

Enhanced PMS activation by Mn2O3-loaded h-BN for levofloxacin removal: Unveiling the dominant influence of non-free radical pathway and N-Mn-mediated promotion of stable, long-lived Mn(IV) species

The Mn2O3-loaded hexagonal boron nitride (h-BN-Mn) catalyst for peroxymonosulfate (PMS) activation was successfully synthesized using a one-step calcination process. The h-BN-Mn/PMS system achieved an impressive 97 % levofloxacin removal within a mere 90-minute timeframe. This catalyst, h-BN-Mn, effectively addresses the challenge of elevated manganese leaching rates and exhibits a broad pH degradation spectrum spanning from 3 to 11. Notably, it maintained robust degradation performance over five cycles, showcasing the potential for large-capacity water treatment when integrated with a polyvinylidene fluoride (PVDF) membrane (h-BN-Mn@PVDF), resulting in an 83.8 % removal rate over 6 h. In-depth analysis revealed three distinct degradation pathways. Primarily, the generation of reactive oxygen species (ROS), including singlet oxygen (1O2), played a pivotal role. This was complemented by direct electron transfer from the contaminant to the catalyst-PMS complex, augmented by contributions from Mn(IV) species derived from the complex. This study not only presents a compelling instance of antibiotic degradation through multi-pathway activated PMS but also sheds light on the remarkable synergistic effects achieved by combining manganese oxide with boron and nitrogen compounds.

DUST COLLECTION EFFICIENCY UNDER IN-PHASE TURBULENCE CONDITIONS IN THE PRESENCE OF PHASE TRANSITIONS

The article presents the results of a study of the dust collection efficiency in a regular packing layer of a rotoclone-type hybrid apparatus on the particle inertia index in the presence of phase transition processes. The effect of phase transitions on the efficiency of gas purification processes under inphase turbulence conditions is considered. Based on the conditions of stability of the in-phase vortex formation regime of the gas phase in a regular packing layer, the dominant influence of turbulent diffusion mechanisms on the intensity of phase transition processes and, as a consequence, on the dust collection efficiency has been established. In this case, the predominant influence is in the area of highly dispersed and finely dispersed dust fractions. The results of the experimental studying the patterns of dust collection efficiency depending on the particle inertia index in the presence of phase transition processes are presented. The studies were carried out for three phase transition modes: condensation of vaporsfrom a vapour-gas mixture, evaporation of a spraying liquid as well as a neutral mode. Using A.N. Kolmogorov’s hypothesis,the basic equations and results of calculating the numerical values of local characteristics of a turbulent gas flow in a regular packing layer are presented under the assumption of isotropic turbulence realized in a layer of a regular packing, whose local characteristics do not depend on coordinates and direction.

The ecological–hydrological regime of the Han River basin under changing conditions: The coupled influence of human activities and climate change

AbstractBecause of the confluence of human activities and climate change, the hydrological regime in the Han River basin has substantially evolved, necessitating a multi‐faceted, quantitative analysis of the causative factors. Employing cross‐wavelet analysis, we examined nonlinear relationships between runoff and meteorological variables. Additionally, we assessed hydrological indicators via the IHA index and RVA, then quantified the drivers of runoff variations across different time scales using the Budyko hypothesis and a Generalized Regression Neural Network (GRNN) model. The findings reveal the presence of sustained resonance periods within the climate‐runoff system, notably concentrated in 9‐ to 15‐month intervals during the years 1985–1994, 1995–2012, and 2014–2018, with a confidence level of 95%. Overall, the basin exhibited moderate change (41.66%), with 15 indicators displaying varying degrees of moderate to high transformation. These shifts underscore significant ecosystem transformations. The influence of driving factors on runoff varies across temporal scales. On an annual scale, human activities predominantly shape runoff changes (52.35%), while meteorological factors contribute significantly (47.65%). Conversely, at the monthly scale, climate change emerges as the dominant influence on runoff patterns in June and September, with human activities maintaining a principal role in other months, notably exceeding 90% even in November.

Composition and size distribution of wintertime inorganic aerosols at ground and alpine regions of northwest China

Water-soluble inorganic ions (WSIIs) play a pivotal role in atmospheric chemical reactions, particularly influencing the formation of secondary particulate matter. A comprehensive grasp of the vertical distribution of atmospheric pollutants holds immense significance in understanding the diffusion and transportation of these pollutants. This study investigates the WSIIs of PM2.5 and size-segregated particles at the top (∼2060 m a.s.l.) and foot of Mt. Hua during the winter of 2020. All the measured ions present significant higher concentrations (1.9∼6.9 times) at the foot than the top. Cl− and K+ at the foot are more than 4 times of those at the top, whereas Ca2+ and Mg2+ are only 1.3–1.9 times higher. The particle size distribution of NO3−, SO42−, K+ and Cl− demonstrate a single peak distribution (0.7–1.1 µm) at the foot, but with a bimodal distribution (0.7–1.1 µm and 4.7–5.8 µm) at the top. These differences suggest that the aerosol at the alpine region is mainly transported via long-distance from Northwest/North China, but limited influenced by vertical transport through valley breeze. The changes of concentration and size distribution of WSIIs in dust event and non-dust period indicate that the effects of dust event on aerosols at ground surface were weaker than that of the free troposphere of Guanzhong Plain. Notably, our study underscores the dominant influence of NO3− in shaping the gas-particle distribution of ammonia within the winter free troposphere. Our results highlight the significant role of long-range transport on aerosols in the free troposphere in Guanzhong Plain, Northwest China.
