Faktor-Faktor yang Memengaruhi Produksi Manggis (Garcinia Mangostana) Di Desa Puspahiang Kecamatan Puspahiang Kabupaten Tasikmalaya

Mangosteen is one of the prospective horticultural commodities in Indonesia. It is a perennial plant with a lifespan of several decades. On average, mangosteen trees in Indonesia can produce 30-70 kg of fruit per tree in a single harvest per year, which is lower compared to Malaysia, Thailand, and India where yields can reach 200-300 kg of fruit per tree. The primary mangosteen production centers in Indonesia are located in West Java Province, specifically in Tasikmalaya, Subang, and Sukabumi. This research was conducted to identify the factors influencing mangosteen production. The research methodology employed a survey approach, collecting primary data directly from respondents (mangosteen farmers) and secondary data obtained from the Tasikmalaya District Central Statistics Agency. The study was conducted in Puspahiang Village, Puspahiang District, Tasikmalaya Regency, and simple random sampling was used for sample selection. The impact of production factors was analyzed using the Cobb-Douglas production function equation model. To assess the simultaneous effect, an F-test was conducted, and for the partial effects, a t-test was employed. The research findings indicate that variables such as land area, number of trees, organic fertilizers, labor force, and tree age collectively influence mangosteen production. Additionally, when examined individually, land area, number of trees, organic fertilizers, labor force, and tree age each have a significant impact on mangosteen production. The scale of production results suggests that a 1 percent increase in input will lead to a 2.216 percent increase in mangosteen production, indicating an increasing return scale.

Identifying Factors Affecting Waste Generation in West Java in 2021 Using Spatial Regression

Responsible consumption and production is the 12th of the seventeen SDGs which is difficult for developing countries to achieve due to high waste production. Indonesia is the second largest producer of food waste in the world. Garbage is solid waste generated from community activities. Population density is an indicator to estimate the amount of waste generated in an area. The choice of West Java Province as the research area is based on the fact that this Province has the second highest population density in Indonesia. This study aimed to determine the predictors/factors that influence waste production in the districts/cities of West Java Province. The data used in this study are total waste as a response variable and GRDP (gross domestic product), total spending per capita, average length of schooling, literacy rate, number of MSMEs (micro, small, and medium enterprises), and several recreational and tourism places, the number of people's markets, and the number of restaurants as predictors. The methods used in this research are spatial autoregressive regression/SAR, spatial Lag-X/SLX, and spatial Durbin/SDM. The results of this study show that the SAR is the best model with the lowest BIC (74.442) and pseudo-R-squared (0.7934). Factors that significantly affect total waste production are literacy levels, the number of MSMEs, the number of traditional markets, and the number of recreational and tourist places.

Spatial vulnerability assessment of climate-related disasters in the Rebana Metropolitan Coastal Area, West Java Province

Human activities have become the main significant factor of the occurrence of climate change. Because of this phenomenon, the negative impacts of climate change influence human life itself, especially for the people who live in coastal area. One part of the Rebana Metropolitan Area in West Java Province is the coastal area consisting of Indramayu, Subang, and Cirebon regencies, which is closely related to climate-related disasters issues, such as coastal flooding and sea-level rise. To adapt the negative impacts of climate change, the local decision-makers should know the vulnerability to climate-related disasters. Therefore, the vulnerability assessment of climate-related disasters should be conducted. The spatial assessment was applied in this study to give a deeper perspective on the spatial vulnerability index. This study used georeferenced statistical data of three aspects (physical, geological, and socio-economical). These data then were overlaid with the support of the Geographical Information System (GIS) and eventually produced the vulnerability index for each zone. Based on the result, the Rebana Metropolitan Coastal Area has high vulnerability indexes (9 of 16 districts in these three coastal areas are very vulnerable). Two reasons have been identified. First, the intensity of rainfall and sea-level rise index that occurs annually in Indramayu and Subang is very high. Second, at the same time, these regencies have many vital infrastructures that make the massive potential of losses when climate-related disasters happen in the future. For the Cirebon case, the lack of supportive socio-economy situation in the coastal area has become the main factor for its vulnerability index. Based on these findings, the decision-makers could create different approaches to improve the resilience of each area. In Indramayu and Subang cases, their resilience could be strategically improved by strengthening their physical aspects, especially by ensuring the government protects their vital infrastructures. Meanwhile, for the Cirebon case, the government could be more concerned with its population density and income per capita for each district so that more people could avoid the coastal disaster directly and push their livelihood up in the more uncertain environment.

Analysis of improving innovative work behaviour of vocational high school teachers in terms of servant leadership with knowledge sharing as an intervening variable

The purpose of this research is to describe the innovative work behavior of vocational high school teachers in terms of servant leadership which is intervened by knowledge sharing. This research uses a quantitative approach with a survey method. The sampling technique was simple random sampling which came from vocational high school teachers from the provinces of East Java, Central Java, West Java, DKI Jakarta, Banten, Riau Islands, and South Sumatra with a total of 165 teachers. Data analysis techniques using descriptive analysis and path analysis. Results: The dimension of the teacher's innovative work behavior, namely with the intent of benefit to the organization has the highest score and the idea promotion dimension has the lowest score. Servant leadership has a positive and significant influence on knowledge sharing with a contribution of 42.3%. knowledge sharing has a positive and significant influence on innovative work behavior with a contribution of 58.4%. Knowledge sharing cannot be an intervening variable of servant leadership on innovative work behavior because the path analysis results show that servant leadership does not directly affect innovative work behavior through knowledge sharing. The implication is that city or district education offices must further enhance the idea promotion exploration of teachers through training or workshops and maintain that with the intent of benefit to the organization of teachers through servant leadership style and knowledge sharing of teachers and school principals.

Analisis Pembiayaan Pembangunan Dengan Penerbitan Surat Utang (Obligasi) Daerah Studi Kasus Pada Pemerintah Kota Bogor

ABSTRACT Law Number 23 of 2014 concerning Regional Government mandates that local governments play an important role in determining the success or failure of creating self-reliance, but in practice, local governments encounter limitations in funding sources. Most of the districts and cities depend heavily on the transfer funds provided by the Central Government to the regions, be it Revenue Sharing Funds (DBH), General Allocation Funds (DAU), and Special Allocation Funds (DAK). Another source of income is from the limited Regional Original Revenue (PAD). Bogor City Government is one of the cities in West Java Province that has been given authority by the center to carry out regional autonomy. By handing over this authority, of course, the government hopes that the Bogor City government can explore the potential of the region to finance its development to reduce dependence on the central government.

The Relationship Between Human Host and Environmental Factors on the Severity of Pneumonia Among Under-Five Children in West Java Province

Pneumonia cases in West Java Province 2018 were ranked first as the province with the highest number of cases in Indonesia with a prevalence of 58.80%. About 7-13% of severe pneumonia patients with an increased risk of death in children require intensive care. This study aims to determine the relationship between host and environmental factors on the severity of pneumonia in children under five years. The research method used cross-sectional study design approach. Data analysis techniques used chi-square, fisher's exact, and multiple logistic regression tests. The population in this study was 2,338 children under five years aged 12-59 months in West Java Province for the 2018 period, while the sample consisted of 132 respondents who met the inclusion criteria and were recorded in RISKESDAS 2018. The results showed that there was a significant relationship between host factors and the severity of pneumonia, namely prematurity (aOR= 2.446; 95% CI=1.113-5.376), while environmental factors that have a significant relationship on the severity of pneumonia, namely the habit of opening windows (aOR= 2.963; 95% CI=1.342-6.544). There is no relationship between Low Birth Weight (LBW), home ventilation conditions and lighting intensity. The most dominant factor in the severity of pneumonia is that the habit of opening windows does not meet the risk of 2.9 times higher severity of pneumonia in children under five years. This study concludes a relationship between prematurity and the habit of opening windows on the severity of pneumonia.

Simulasi Turbin Portabel Jenis Cross Flow Untuk Pembangkit Listrik Tenaga Pikohidro (PLTPH)

In Indonesia, especially West Java Province, there are quite a lot of rivers with quite high or mountainous elevation differences, generally, these rivers are used as tourist attractions which are located far from residential areas. To meet electricity needs, an alternative is to convert the river flow into electricity, either used for lighting or simply to charge electronic devices such as gadgets. One solution is to make small turbines that can be moved and can be produced in large quantities. Through this activity, a simulation analysis will be carried out on previously available designs so that existing weaknesses can be seen so that they can become evaluation material for subsequent designs. The stages of activities carried out include the study stage of simulations using CFD to determine deficiencies in inflow performance and also serve as material for the evaluation of subsequent designs. From the results of the simulation that has been carried out, the flow in the existing equipment has a decrease when it hits the cross-flow turbine blade so that the flow is not at its optimal speed, besides that the kinetic energy has not been completely converted into mechanical energy which can be seen in the velocity distribution picture, namely the flow still has a speed when it enters the outlet hole, this becomes a loss for the tool and becomes a note for evaluation for further tool design.

Effectiveness of glyphosate potassium 660 g/L herbicide in controlling weeds at productive tea plants (Camellia sinensis (L.) O. Kuntze)

Tea ranks among Indonesia's prominent export commodities, and international market competition necessitates the cultivation of tea plants with maximum efficiency to sustain production levels. An eminent challenge in preserving the productivity of tea plants is the pervasive growth of weeds, which engender competitive pressures on tea plants, consequently diminishing crop yields. This research was conducted during January to May, 2023 to test the effectiveness of Glyphosate Potassium 660 g/L herbicide in controlling various types of weeds in tea plantations. Glyphosate potassium herbicide works by inhibiting the 5-enolpiruvil-shikimat-3-phosphate synthase (EPSPS) enzyme which plays a role in the formation of aromatic amino acids in plants. The research was conducted at the PTPN VIII Rancabali tea plantation, Bandung Regency, West Java Province, Indonesia. The experimental design used was a Randomized Block Design (RBD) with seven treatments and four replications, resulting in 28 experimental plots. Treatments included the application of Glyphosate Potassium 660 g/L herbicide with doses of 0.75 L/ha, 1.125 L/ha, 1.5 L/ha, 1.875 L/ha, 2.25 L/ha, manual weeding, and control (without treatment). The results showed that the herbicide with Glyphosate Potassium 660 g/L active ingredient at doses ranging from 0.75 L/ha to 2.25 L/ha was effective to control broadleaf weeds such as Ageratum conyzoides, Bidens pilosa, Galinsoga parviflora, and Diodia sarmentosa, grassy weeds such as Setaria plicata and Axonopus compressus and other weeds (Drymaria cordata, Synedrella nodyflora, Erechtithes valerianifolia and Clidemia hirta) until the observation at 12 Weeks After Application (WAA) without causing phytotoxicity on the tea plants.

Differential DHA and EPA Levels in Women with Preterm and Term Births: A Tertiary Hospital Study in Indonesia.

BACKGROUND Preterm birth is one of the main causes of neonatal death worldwide. One strategy focused on preventing preterm birth is the administration of long chain polyunsaturated fatty acids (LCPUFAs) during pregnancy. Omega-3 LCPUFAs, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are essential in metabolic and physiological processes during embryonic and fetal development. This study aimed to compare DHA and EPA levels in 44 women with preterm births and 44 women with term births at a tertiary hospital in West Java Province, Indonesia, between November 2022 and March 2023. MATERIAL AND METHODS A total of 88 patients in this study consisted of 44 patients with term births (≥37 gestational weeks) and 44 patients with preterm births (<37 gestational weeks) at a tertiary hospital in West Java Province, Indonesia. This observational, cross-sectional study was conducted from November 2022 to March 2023. Using the enzyme-linked immunosorbent assay test, maternal DHA and EPA levels were investigated. IBM SPSS 24.0 was used to statistically measure outcomes. RESULTS Average maternal DHA and EPA levels in patients with preterm births were significantly lower than those in term births. Preterm labor risk was further increased by DHA levels of ≤5.70 µg/mL (OR=441.00, P=0.000) and EPA levels ≤3971.54 µg/mL (OR=441.00, P=0.000). CONCLUSIONS Since the average maternal DHA and EPA levels were significantly lower in patients with preterm births, adequate intake of omega-3 LCPUFA in early pregnancy and consistency with existing nutritional guidelines was associated with a lower risk of preterm delivery for pregnant women.

Pengaruh Kepadatan Penduduk Terhadap Produk Domestik Regional Bruto (PDRB) Per Kapita Provinsi Jawa Barat Tahun 2022

This study delves into the correlation between population density and Gross Regional Domestic Product (GRDP) in West Java Province during 2022. Employing a quantitative approach, the analysis utilizes pertinent statistical data from the West Java Province Central Statistics Agency. Employing a descriptive correlational design, this research employs a simple linear regression method to scrutinize the relationship between population density and GRDP. The analysis findings reveal a feeble connection between population density and GRDP, with population density exerting a mere 2.7% influence on GRDP. These findings underscore the role of other factors such as Human Resources (HR), Natural Resources (NR), and regional topography in determining the GRDP level of a region.

Perilaku Petani Milenial Provinsi Jawa Barat dalam Penerapan Climate-Smart Agriculture (CSA) pada Tanaman Hortikultura

Millennial farmers become superior and competitive human resources as determinants of the progress of agricultural development. Millennial farmers must be adaptive to digitalization technology and innovation and environmentally friendly cultivation techniques to face agricultural development, including climate change challenges. Climate-smart agriculture (CSA) behavior is the strategic effort of millennial farmers as an approach to dealing with the impacts of climate change on the agricultural sector, as well as efforts by the agricultural industry to reduce its impact on climate change through efficient management of crops, land and soil, and water. The management is based on three pillars of CSA: 1) Increasing agricultural productivity and income, 2) Improving adaptation and resilience to climate change, and 3) Reducing greenhouse gas emissions. This study aims to analyze CSA implementation behavior based on the Theory of Planned Behavior (TPB) by examining the direct and indirect effects of attitude variables, subjective norms, perceived behavioral control, and intentions. These variables are measured by integrating TPB with the CSA context. The research sample was 198 respondents of Millennial Farmer Ambassadors and Andalan Farmer Ambassadors in West Java Province, conducted in 2023. This research uses a quantitative approach with the Structural Equation Model-Partial Least Square (SEM-PLS) method to analyze complex models with many variables—data collection techniques using questionnaire instruments that have been valid and reliable. The results showed that attitude, perceived behavioral control, and intention significantly influence behavior both directly and indirectly through intention (p-value &lt; α 0.05). Meanwhile, subjective norms do not substantially affect behavior directly or indirectly through intention (p-value &gt; α 0.05). So, it is necessary to develop interventions that strengthen the formation of positive intentions and the need for practical support for subjective norms related to CSA implementation behavior in millennial farmers.

ANALISIS PENGARUH FAKTOR RISIKO PENYAKIT PNEUMONIA TERHADAP ANGKA MORTALITAS BAYI DAN BALITA MENGGUNAKAN REGRESI POISSON DAN REGRESI BINOMIAL NEGATIF (Studi Kasus : Provinsi Jawa Barat)

Pneumonia is an acute infectious disease that attacks lungs caused by viruses, bacteria or fungi. This infection can be life-threatening for anyone, especially infants, children and people aged 65 years. In 2020 in West Java Province infant and toddler deaths due to pneumonia reached 122 cases. This study aims to analyze the factors that influence infant and under-five mortality rates by comparing Poisson regression and negative binomial regression, as well as modeling significant factors. The handling of overdispersion cases in Poisson regression can be done with alternative methods, one of which is the negative binomial regression method. This study uses secondary data obtained from the Health Profile of West Java Province 2020. The results of the study show that negative binomial regression handles overdispersion cases in data on the number of infant and under-five deaths due to pneumonia in West Java Province in 2020. Factors that influence infant mortality rates and toddlers due to pneumonia are low birth weight babies (X2) and population density (X4).
