Abstract

The ISO 14001 environmental management system has been implemented by many types of organizations, but there are still many differences of opinion related to the effectiveness of the implementation of this standard on improving environmental performance in an organization. The effectiveness of the implementation of environmental management system standards is highly dependent on strategic planing gaps with other management systems integrated in an organization. The balanced scorecard concept has provided a comprehensive framework for translating the company's strategic planning into more comprehensive performance measurement. To analyze the condition of strategic planing in an integrated management system that has adopted the concept of a balanced scorecard at PT. Xyz, researchers used a descriptive analysis method, the results obtained that strategic planning in 2014, 2015 and 2018 have coherence, but in 2016-2017 it is not coherent, which means that strategic planning starts not in accordance with the attributes of the balanced scorecard concept. Correlation test method is used to analyze the effect of strategic planning with environmental performance and economic performance at PT. Xyz, the results obtained that strategic planning in an integrated management system that adopts a balanced scorecard has a positive effect on environmental performance but does not have a positive effect on economic performance. Strategic planning interventions through the formulation of corporate strategy using the DEMATEL method obtained corporate strategy impact relations map which formulates the six criteria of the most priority corporate strategy recommendations for improving environmental performance and economic performance at PT. Xyz in the future

Abstract

Establishing an in-situ conservation reserve is one of the strategic approaches to conserving an ecosystem and protecting it from immediate threats, including deforestation and land-use conversion. Kalimantan is one of the islands in Indonesia that is currently threatened by deforestation. To protect East Kalimantan diversity, mainly in Balikpapan, an in-situ conservation reserve has been established in Gunung Sepuluh Timur (GST) forest. In contrast, the information on tree diversity and how the presence of tree community within the forest can benefit the ecosystem are still limited. This research aims to assess the potential benefits and carbon storage of the GST conservation forest. The assessment method applied tree, pole, and sapling surveys combined with forest cover analysis using GIS and NDVI (Normalized Difference Vegetation Index) approaches. The GST contained 56 tree species, 25 pole species, and 16 sapling species. Diversity (H’) at tree stages was the highest (H’ = 0.759; 95%CI: 0.64-0.88) and H’ at sapling stages was the lowest (H’ = 0.719; 95%CI: 0.51-0.92). The carbon service potential of GST forest was 87.04 t C/ha on average. It was estimated that the economic benefits of GST in sequestering carbon based on the compliance market rate were equal to US$ 189,758/year.

Abstract

Abstract. The growing economic sector and people’s living standards growth have caused the number of domestic solid waste in urban areas to increase. The paper aims to analyze correlation between perceived behavioral control and intention to sort waste towards waste sorting behavior at work by applying Theory of Planned Behavior (TPB) from Icek Ajzen. This study uses a quantitative approach towards 251 respondents using likert scale (1 – 4) as the instrument. The measuring instrument are Pearson Product Moment and Multiple Correlation. The results of this study indicate that (1) there is a correlation between perceived behavioral control and waste sorting behavior (0.371); (2) there is a correlation between intention to sort waste and waste sorting behavior (0.313); (3) there is a strong correlation between perceived behavioral control and intention to sort waste (0.802); (4) correlation between perceived behavioral control and intention towards waste sorting behavior shows R2 = 0.372. Company’s intervention through the provision of appropriate types of trash bins with close proximity to the employee's position at work is needed to improve waste sorting behavior. Keywords: intention, perceived behavioral control, TPB, waste sorting

Abstract

Penggunaan batubara untuk produksi energi listrik menimbulkan berbagai dampak lingkungan seperti deforestasi hutan untuk pembukaan lahan tambang batubara dan pencemaran udara dari limbah fly ash. Jumlah timbulan limbah fly ash harus dikendalikan. Limbah fly ash dapat menjadi barang yang bernilai ekonomis yaitu sebagai bahan pengganti sebagian semen dalam campuran beton. Penggunaan fly ash yang berperan dalam menggantikan sebagian portland semen pada beton dapat mengurangi dampak emisi CO2 karena pembuatan semen portland yang dapat menghasilkan emisi CO2 sebesar 6-8% dari total emisi CO2 antropogenik. Beton cair yang menggunakan fly ash dalam campurannya dapat menghasilkan produksi beton yang lebih berkelanjutan. Dampak lingkungan dari penggunaan fly ash pada produksi beton cair dapat dianalisis dengan penilaian siklus hidup. Kajian pada artikel ini membandingkan dua skenario simulasi yaitu simulasi pada beton menggunakan 0% fly ash dan 25% fly ash. Penelitian ini bertujuan untuk mengkaji dampak emisi CO2 pada produksi beton fly ash. Penelitian ini berkontribusi untuk membuktikan penelitian-penelitian sebelumnya bahwa penggunaan fly ash dapat meminimalisir emisi CO2 dan mendukung peningkatan pemanfaatan limbah fly ash khususnya di bidang konstruksi.  Unit Fungsional pada penelitian ini adalah menganalisis dampak lingkungan yang menyumbang emisi gas CO2 dalam proses produksi 1 m3 beton. System boundary pada penelitian ini adalah cradle-to-gate yang meliputi proses incoming material dan proses produksi beton, yang digunakan untuk menentukan dampak lingkungan dari daur hidup produksinya. Pengolahan data untuk evaluasi dampak lingkungan pada penelitian ini menggunakan software SimaPro 9.3.0.3 dengan database ecoinvent 3.0. Studi menunjukkan bahwa berbagai beton menggunakan 25% fly ash memiliki dampak emisi GWP lebih kecil pada lingkungan, yaitu 298 KgCO2, lebih kecil dibandingkan beton non fly ash yang menghasilkan emisi GWP 347 KgCO2.

Abstract

Introduction: People prefer to use groundwater for daily needs to piped water in Indonesia. However, population growth and the construction of residential homes can hugely affect the quality of groundwater. The study aims to examine the relationship between groundwater quality and its influencing factors. Methods: This study was conducted with a quantitative approach and a survey method. Primary and secondary data were required in this study. The variables examined in this study were groundwater quality as seen from its biological parameters and influencing factors which consisted of internal and external factors. Results and Discussion: The results show that the highest coliform bacteria content was found in Cipinang Melayu at 200 MPN/100 mL concentrations in 2019 and 2020, as well as 100 MPN/100 mL in 2021, followed by Pinang Ranti. The highest coliform content was discovered in Halim Perdana Kusuma well number 3 at 50 MPN/100 mL concentration. Groundwater contains coliform because of internal influencing factors as well as external factors. Coliform content and its influence factors were both significantly correlated with a P-value < 0.05 (correlation coefficient = 0.201 for internal factors; correlation coefficient = -0.144 for external factors). The groundwater quality and internal factors were correlated with a correlation coefficient of 0.634; meanwhile, the groundwater quality was significantly correlated with external factors with a correlation coefficient of 0.656. Conclusion: Groundwater quality was not aligned with standards for drinking water as evaluated from the biological parameters. Both internal and external factors influence the Total coliform content.

Abstract

Purwokerto is planning to build Tempat Pengolahan Sampah Reduce, Reuse, Recycle (TPS 3R) in each of its villages, this is due to minimize the quantity of waste that will be transported to Tempat Pembuangan Akhir (TPA), 12 TPS 3R have been built in 12 urban villages ini this city. South Purwoketo Subdistrict only has 1 TPS 3R in 1 village while there are 6 village that do not yet have TPS 3R, so the location of this research is in Purwokerto Kulon which is close to the activity center of Purwokerto. This study aims to find an alternative location for TPS 3R in Kelurahan Purwokerto Kulon. The method used in this study uses the AHP method and Spatial Analysis. This study resulted in locations that were “Very Appropriate”, “Sufficiently Appropriate” and “Not Appropriate”. There are 3 alternative location points with the "Very Appropriate" category to build TPS 3R in Purwokerto Kulon. These 3 locations are in the middle of the Purwokerto Kulon Village area, these 3 locations are on vacant land with a land area of >200 m² with a slope of 0% - 8% or flat, located > 200 m from a body of water/river and these three locations located in an area with minimal human activity. These three alternative locations are able to serve in waste processing in Purwokerto Kulon Village because their placement is close to the service area within a radius of no more than 1 Km

Abstract

Waste pickers in Jambi city reduce solid waste by collecting and sorting recycled waste at the ‘Solid Waste Temporary Shelters’ or Tempat Pembuangan Sementara (TPS). However, most waste pickers cannot improve their performance due to challenges confronting waste pickers and lack of attention from the government and the public. This research identified and quantified the solid waste collected and marketed by individual waste pickers and collectors ‘pengepul’. Convenience sampling methods with literature reviews, questionnaires, and interviews were carried out in this study. Most respondents were male waste pickers, 67%, and women, 33% (n=100). The average daily collection rate of male waste pickers is 10.43 kg/day. For female waste, pickers are 7.92 kg/day (waste category: plastic bottles, cardboard, and wastepaper), with an estimated recycling rate of 0.09%-0.89%. Meanwhile, collectors have an average sales rate of 2-5.5 tons/month, with an estimated recycling rate of 1.5%. The recycling value of waste pickers and collectors could be more optimal, impacting the average income of waste pickers Rp. 581,250/month which showed that the market is neither profitable nor socially protected. The research findings could help develop a waste pickers' integrated system to improve the implementation of the circular economy.

Abstract

The Cakung River is a river located east of Jakarta and empties directly into the Cilincing estuary, on the coast of DKI Jakarta. The Cakung River crosses a densely populated area and becomes a waste disposal site for various types of industries, resulting in a decline in river water quality. The decline in the quality of the Cakung River will affect Jakarta’s coastal area which has a strategic ecological function. This study aims to analyze the water quality and water quality status of the Cakung River using the pollution index method. The results were also compared with measurements in 2021 and 2019. Laboratory analysis showed that the main pollutant parameters such as TSS, BOD, COD, and Faecal coliform exceeded the quality standards at all sampling points. The range of TSS values was 42-3450 mg/L, BOD 11.1-23.64 mg/L, COD 30-100 mg/L, Faecal coliform 5x106-9x106 MPN/100 mL. The pollution index calculation results show that the Cakung River is severely polluted with index value ranging from 13.92-14.86 and the level of severe pollution has also been going on since 2019. Therefore, serious efforts to control pollution in the Cakung River are needed.

Abstract

The COVID-19 pandemic has significantly affected various countries worldwide, including Indonesia. This study specifically examines the spatial distribution pattern of COVID-19 cases among sub-districts in DKI Jakarta and its neighboring areas. The study investigates the impact of spatial characteristics such as building density, population density, road network connectivity, and accessibility, as well as infrastructure completeness. A spatial regression model was employed to analyze the influence and pattern of COVID-19 case distribution among sub-districts. Spatial modeling indicates that geographic location has an effect on the data, often referred to as the autocorrelation effect. Moran’s Index was used to test the relationship between district locations and the number and growth rate of cases.The study findings reveal a positive spatial autocorrelation in the growth rate pattern of COVID-19 cases among sub-districts and clusters in DKI Jakarta and its surrounding areas. The spatial regression model, specifically the Spatial Autoregressive Model (SAR), identifies road connectivity, number of health centers, building density, and population density as spatial variables that significantly influence the rate of COVID-19 cases.
