This research aims to analyze the role of the Special Job Exchange (BKK) in increasing the absorption of Palembang City State Vocational School alumni in the world of work. BKK is one of the units that supports the labor absorption process by connecting the world of education and the world of industry. This research uses a qualitative approach with a case study method involving primary data through in-depth interviews with BKK, alumni and collaborating companies. The research results show that BKK has a significant role in facilitating Palembang City State Vocational School alumni in obtaining employment opportunities. Apart from that, BKK also provides training and information regarding job vacancies that are relevant to the skills possessed by alumni. However, several challenges are still faced, such as a lack of certain skills needed by companies and limited collaboration networks with the industrial world. This research recommends the need to improve the quality of training and expand the cooperation network between vocational schools and the industrial world to increase the effectiveness of BKK in accelerating workforce absorption.  

During the coal stockpiling process, the quality of coal may increase or decrease due to direct exposure to open environmental conditions, which can lead to changes in its characteristics. The longer the coal is stored in an open area, the more it undergoes changes caused by rainfall, heat, and air exposure, resulting in an increase in moisture content and ash content, while the calorific value decreases. Therefore, this research was conducted to determine the optimal coal stockpiling duration at the ROM coal stockpile to ensure that the calorific value does not significantly decrease. Coal sampling was carried out every two days from the initial time of stockpiling. After a two-month stockpiling period, the final coal quality results showed a total moisture of 13.89% (ar), inherent moisture of 15.95% (ad), ash content of 4.59% (ad), volatile matter of 40.3% (ad), and fixed carbon of 39.16% (ad). Based on these results, it can be concluded that the recommended storage duration for MCV-HS type coal at the ROM coal stockpile is 154 days. The laboratory analysis results obtained during the research indicate that the longer the coal is stored, the higher the moisture content and ash content become, while the calorific value continues to decrease. This occurs due to water absorption and oxidation reactions that take place during the coal storage period in the ROM coal stockpile.

Abstract. This study aims to analyze the effect of four-wheeled vehicle production and imports on the unemployment rate in West Java Province during the 2016–2023 period. The background of the study stems from the fluctuating conditions of vehicle production and imports, as well as West Java's unemployment rate, which tends to be higher than the national average. The study employed a quantitative approach with secondary data obtained from Statistics Indonesia (BPS) and the Indonesian Association of Indonesian Automotive Manufacturers (GAIKINDO). The analytical method used was multiple linear regression to determine the simultaneous and partial effects between variables. The results show that four-wheeled vehicle production and imports simultaneously have a significant effect on the unemployment rate. Partially, four-wheeled vehicle production has a significant negative effect, meaning that increased production can reduce the unemployment rate in West Java. Conversely, four-wheeled vehicle imports have no significant effect on the unemployment rate, so increased imports do not directly affect labor absorption. The coefficient of determination of 83.4% indicates that production and imports contribute significantly to explaining variations in the unemployment rate. These research findings emphasize the importance of strengthening the automotive industry sector as a strategy to reduce unemployment in West Java.

Job opportunities are available for prospective workers who are looking for work. The existence of job opportunities in an area will greatly open up opportunities for labor absorption, such as opening job opportunities for local inter-worker (AKL) workers, which is the placement of workers between regencies/cities working within one province. The research method used in this study is a descriptive research method with a qualitative approach. Data collection techniques were carried out through interviews, observations, and documentation at the Pematang Siantar City Manpower Office. All data obtained will be analyzed qualitatively with all data collected using the theory of Fred R. David (2019), namely Strategy Implementation with 3 variables, namely Strategy Development, Human Resource Allocation, and Determining Budget Funds. Based on the research that has been conducted, it can be seen that the Pematang Siantar City Manpower Office has attempted to provide the best solution by designing several programs to provide more job opportunities. Viewed from the development strategy perspective, the Manpower Office has realized several work programs such as job fair events held, competency-based training programs that are already running, and focusing on information about the labor market. The analysis revealed several shortcomings, including the government's inconsistency in implementing the program. Furthermore, the government's human resource allocation has been unable to improve the quality of human resources, particularly in Pematang Siantar City. Furthermore, the government's budget allocation has been ineffective in determining appropriate funding, resulting in limited funding and ineffective program implementation.

This study investigates the impact of population growth and the Human Development Index (HDI) on economic growth and unemployment in East Kalimantan Province using path analysis with secondary data from 2014–2023. Population growth and human development are two critical demographic and socio-economic factors that often generate complex effects on regional economic performance. The results indicate that population growth has a negative and significant effect on economic growth, highlighting the pressure that rapid demographic expansion places on natural resources, infrastructure, and employment absorption capacity. Conversely, HDI demonstrates a positive and significant relationship with economic growth, suggesting that improvements in education, health, and income contribute to higher productivity and competitiveness. On the other hand, the direct effect of population growth and HDI on unemployment is negative but statistically insignificant, which implies that the availability of jobs and structural conditions of the labor market are more influential than demographic changes alone. Interestingly, economic growth shows a negative and significant effect on unemployment, supporting the classical theory that sustained economic expansion generates employment opportunities and reduces joblessness. Mediation tests reveal that economic growth does not significantly mediate the relationship between population growth or HDI and unemployment, underscoring that unemployment dynamics in East Kalimantan are influenced by broader structural factors such as sectoral concentration, policy effectiveness, and industrial diversification. These findings highlight the importance of integrating demographic management, human capital development, and sectoral economic strategies in policy formulation. Strengthening human development while controlling excessive population growth can provide a solid foundation for inclusive and sustainable economic progress in East Kalimantan.

This study aims to analyze the significance level of the influence of minimum wages and inflation on labor absorption in Indonesia. The research applies a quantitative approach with field research design using secondary data in the form of time series published by the Central Bureau of Statistics (BPS) for the period 1993–2023. Data collection was carried out through documentation methods, while data analysis employed multiple linear regression processed using EViews 12 software.The results indicate that, partially, the minimum wage variable has a positive and significant effect on labor absorption in Indonesia. This finding suggests that an increase in the minimum wage contributes to higher employment absorption during the study period. In contrast, the inflation variable shows a positive relationship but does not significantly affect labor absorption. This implies that rising inflation does not directly reduce or increase employment opportunities in a statistically significant manner. Simultaneously, minimum wages and inflation jointly have a significant impact on labor absorption.These findings highlight the crucial role of wage policy in maintaining labor market stability, while the effect of inflation tends to be indirect. Therefore, the government is expected to formulate adaptive minimum wage policies that take inflation into account to create a balance between workers’ welfare and the sustainability of employment opportunities.

The purpose of this study was to determine the effect of the Gross Regional Domestic Product of the Trade and Processing Industry Sectors and Services on the Amount of Labor Absorption in Samarinda City and Balikpapan City. This study uses panel data from 2013 – 2022 in the two cities of Samarinda and Balikapapan using secondary data. Data analysis used a dummy variable multiple linear regression model using SPSS (Statistical Program Social Science) version 23. The results of this study indicate that the GRDP variables in the trade, manufacturing and service sectors together have a significant effect on the amount of labor absorption. The Trade Sector Variable partially has a significant positive effect on Total Labor Absorption. The Processing Industry Sector Variable partially has no significant effect on Total Labor Absorption. And the Service Sector Variable partially has a significant negative effect on Total Labor Absorption.

This study investigates the influence of economic growth, investment, and minimum wage on the open unemployment rate across districts and cities in East Kalimantan Province. The research employs a quantitative descriptive approach with panel data regression analysis, processed using EViews 13 software. Model selection was carried out through the Chow and Hausman tests, which identified the Fixed Effect Model (FEM) as the most appropriate estimation technique. The study utilizes secondary data from 2018 to 2024, obtained from the Central Bureau of Statistics (BPS) and the Investment and One-Stop Integrated Service Office of East Kalimantan Province. The empirical findings demonstrate that economic growth exerts a negative and statistically significant impact on the open unemployment rate, indicating that higher economic growth effectively contributes to reducing unemployment in the region. Foreign Investment (PMA) is found to have a negative but insignificant effect, suggesting that inflows of foreign capital alone do not directly translate into job creation unless accompanied by supporting policies and local labor absorption capacity. In contrast, Domestic Investment (PMDN) shows a positive yet statistically insignificant relationship with unemployment, reflecting the possibility that domestic investments may not always generate sufficient employment opportunities in the short term due to structural constraints or sectoral imbalances. Furthermore, the minimum wage variable has a negative and significant effect on the open unemployment rate, implying that increases in the regional minimum wage can stimulate greater employment absorption and improve labor market conditions. Overall, the results highlight the importance of fostering sustained economic growth and designing investment policies that are more labor-intensive to optimize employment creation. Additionally, the findings emphasize the strategic role of minimum wage policy in supporting job opportunities while safeguarding workers’ welfare.

Rabbit skin is one by-product that can be utilized for its aesthetic value through a tanning process so that the skin is resistant to destructive bacteria, namely Pseudomonas aeruginosa and Staphylococcus aureus. Furtigh is the strengthening of fur in the tanning process, in this research the furtigh process uses formalin so that rabbit fur is stronger and lasts longer. The purpose of this research was to determine the appropriate concentration of formalin and storage length used in rabbit fur tanning in the terms of pliability, tensile strength, fur loss and water absorption. The method used in this research is a laboratory experimental method using a Completely Randomized Design (CRD) with a nested design consisting of 4 treatment and repeated 4 times each. This treatment used formalin of 10%, 15%, 20% and 25%. Variables tested included pliability, tensile strength, fur loss and water absorption. Processing data using analyzed by Analysis of Variance (ANNOVA) and continued with the Duncan Multiple Range Test (DMRT). The results showed that different usage of formalin exerted significant influence (P<0,05) on the tear elasticity of tanned rabbit furs with a result of F1: 29,76%; F2: 32,85%; F3: 41,70%; F4: 41,88%. Different concentration usage of formalin have significant influence of tanned rabbit fur (P<0.05) on rabbit skin tensile strength fur tanning with a results of F1: 36.63 N/mm2; F2: 39.69 N/mm2; F3: 43.81 N/mm2; F4: 48.36 N/mm2. Fur loss test showed that the use of different formalin exerted highly significant influence (P<0.01) of tanned rabbit fur loss with a result of F1: 4.15; F2: 3.78; F3: 3.49; F4: 3.40. Water absorption test that the use of different formalin concentration have highly significant influence of tanned rabbit fur (P<0.01) with water absorption with a result of F1: 192.12%; F2: 217.95%; F3: 237.85%; F4: 238.27% on 2 hours of water absorption. Storage length did not have significant influence of tanned rabbit fur (P<0.05) on rabbit skin elasticity, tensile strength, fur loss and water absorption.

This study aims to analyze the relationship between the number of industrial companies, both large-medium and micro-small, with labor absorption in Sidoarjo Regency during the period 2020 to 2023. Sidoarjo Regency, which has a rapidly growing industrial sector, is the location of the study with a focus on the contribution of the industrial sector to reducing unemployment and improving community welfare. The results of the study show that the number of large-medium industrial companies has a significant effect on labor absorption, especially in sectors that require skilled labor. Meanwhile, micro-small industries tend to absorb lower-skilled labor, with most of them in the informal sector. Although there has been an increase in the number of industries, its impact on labor absorption is not always comparable, this is influenced by external factors such as government policies, technological developments, and the quality of the available workforce. Labor absorption also differs by age group, with younger age groups being absorbed more in micro-small industries and older age groups being absorbed more in large-medium industries. This study also shows that sub-districts with better infrastructure have higher labor absorption rates. The suggestion from this research is to improve policies that support equitable industrial development, as well as strengthen skills training programs according to industry needs to increase labor absorption.  

The micro, small, and medium enterprises (MSMEs) sector plays a vital role in sustaining the national economy, particularly in food security and employment absorption. However, this sector remains highly vulnerable to economic disruptions, including large-scale layoffs in the industrial sector. This study aims to examine the socio-economic impacts of layoffs on the sustainability of traditional fish processing businesses. A descriptive qualitative approach was employed, with data collected through semi-structured interviews with a traditional fish processor who has operated since 1990 in Tanjung Morawa, Deli Serdang, North Sumatra. The findings reveal that layoffs have led to a significant decline in consumer purchasing power, resulting in a drop in daily production volume (from 20 to 5–8 baskets) and increased waste due to unsold inventory. The lack of innovation, absence of adaptive strategies, and minimal external support have further exacerbated the business’s vulnerability. Therefore, policy interventions and capacity-building programs are essential to enhance the resilience of MSMEs amid labor market fluctuations.  

This study investigates the influence of Provincial Minimum Wage (PMW), Labor Force Participation Rate (LFPR), and Population Growth Rate (PGR) on Employment Opportunities (EO) across 20 most populous provinces in Indonesia from 2017 to 2024. Using a quantitative approach and panel data sourced from the Central Statistics Agency, the analysis applies the Fixed Effect Model selected through Chow and Hausman tests. The Outcomes indicate that PMW has a significant negative effect on EO, implying that wage increases without corresponding productivity growth can reduce job absorption. Conversely, LFPR has a significant positive effect, reflecting that a higher labor force engagement boosts employment. PGR has a negative but statistically insignificant effect. The F-test confirms that all three variables jointly influence EO. These results highlight the need to harmonize wage regulations, human capital development (HDI), and population planning to support inclusive and sustainable employment in regions experiencing high demographic pressures.

The purpose of this study was to determine and explain the role of salted egg businesses in helping to improve the economy of the community in Kandangan District. Micro and small businesses such as salted egg production have great potential in contributing to household income and local labor absorption. This study uses a case study method with a qualitative approach. Data were collected through field observations, in-depth interviews with salted egg business actors, and documentation of business activities. The results of the study show that salted egg businesses in Kandangan District are not only the main source of income for some people, but also create jobs, encourage economic independence, and increase the purchasing power of local people. In addition, business actors also show creativity in packaging and marketing products, both conventionally and digitally. This study concludes that salted egg businesses can be one of the driving forces of a sustainable local economy if supported by adequate training, market access, and capital.

This study aims to analyze the influence of economic growth and education quality on labor absorption in 27 regencies/cities of West Java Province during the 2020–2024 period using the Random Effect Model (REM) method. The estimation results show that economic growth has a positive and significant effect on labor absorption, with a coefficient of 0.322424 and a p-value of 0.0002. This indicates that regional economic growth contributes to increasing employment opportunities. On the other hand, the quality of education, measured by the average years of schooling, has a negative and insignificant effect on labor absorption, with a coefficient of -0.706782 and a p-value of 0.0755. These findings suggest that improvements in formal education do not automatically lead to increased labor absorption, likely due to a mismatch between graduate qualifications and labor market needs. The Adjusted R-squared value of 0.091650 indicates that the model explains only about 9.16% of the variation in labor absorption, with the remaining variation influenced by other unobserved factors. Therefore, strategic policies are needed, such as the development of labor-intensive sectors and the improvement of vocational education quality and relevance, to optimally enhance labor absorption in West Java.

High Performance Liquid Chromatography (HPLC) is a vital analytical technique used for separation, identification, and quantification of compounds in complex mixtures. This review explores the comparative performance of four detectors employed in the Chemical Laboratory of PT FIP: UV-Visible, Refractive Index (RI), Conductivity, and Evaporative Light Scattering Detector (ELSD). Each detector operates on distinct principles and is selected based on analyte characteristics such as the presence of chromophores, ionic nature, or volatility. The UV-Vis detector remains the most widely used due to its precision and compatibility with chromophoric compounds. However RI, Conductivity, and ELSD detectors serve as essential alternatives for analytes that lack UV absorption, non-ionizing, or exhibit low volatility. This review summarizes the key principles, advantages, limitations, and applications of each detector. The comparative evaluation highlights the strengths and constraints of each system, facilitating method optimization in pharmaceutical analysis.
