Pentahelix Stakeholder Analysis in Developing Ecotourism Based on Paradisaea minor jobiensis Conservation in Sawendui, Yapen Islands
Full text linkSawendui Village, Yapen Islands Regency, has ecotourism potential Paradisaea minor jobiensis. One approach to preserving P. minor jobiensis is the development of ecotourism. Ecotourism development requires pentahelix stakeholder involvement, which consists of the community, businessmen, government, academics, and media, who have different roles, interests, and influences in terms of ecotourism. The objectives of this study were identify stakeholders, measure the level of interest and influence of stakeholders, and classify stakeholders related to P. minor jobiensis-based ecotourism in Sawendui Village. This study identified 16 stakeholders related to ecotourism using pentahelix grouping, qualitative and quantitative methods through data collection using questionnaires and semi-structured interviews. The Snowball Method was used to get respondents from each stakeholder group. Further study classified stakeholders based on their interests and influence as a pentahelix group. The research results showed that not all ecotourism stakeholders have high interest and influence. The community has the highest interest because they get many benefits from ecotourism, while the government has the highest influence because of its strong institutions. The community is included in the subject classification, the government is included in the key player classification, the media is a context setter, and the crowd consists of academics and businessmen. Increasing stakeholder interest and influence is needed to accelerate ecotourism development. Collaboration between stakeholders in ecotourism needs to be carried out. As a key player, the government has the authority to mobilize all stakeholder groups.

No full textPenggunaan herbisida glifosat secara luas menimbulkan masalah lingkungan karena sifatnya yang persisten dan berpotensi mencemari sistem air dan tanah. Mengoptimalkan pengembangan metode adsorpsi yang ramah lingkungan dengan memanfaatkan limbah pabrik kelapa sawit melalui konversi menjadi biochar dan zat humat, dapat mengurangi polusi dan mendukung pengelolaan limbah yang berkelanjutan. Penelitian ini telah melakukan pemodelan adsorpsi isotermal herbisida glifosat menggunakan konversi limbah pabrik kelapa sawit dalam bentuk larutan. Adsorpsi isotermal herbisida glifosat dengan metode kesetimbangan batch. Adsorpsi herbisida glifosat pada limbah pabrik kelapa sawit yang dikonversi dalam bentuk larutan menunjukkan peningkatan dengan meningkatnya konsentrasi glifosat dan pH. Kapasitas adsorpsi dan koefisien herbisida glifosat dengan formulasi 25% biochar-tandan kosong kelapa sawit dan 75% zat humat-padatan dekanter basah adalah 750,53 mg g-1 dan 93,70 L g-1 pada pH 5,2 dan konsentrasi 20,025 mg L-1. Isoterm adsorpsi herbisida glifosat terjadi pada model Freundlich dan Langmuir (Langmuir > Freundlich) di mana, model Freundlich (y = -0,9563x + 4,9729; R² = 0,4961) dengan nilai n (1,04); KF sebesar 93.950,69 (L mg-1)1/n, dan 1/n sebesar 0,96. Sementara itu, model Langmuir (y = 2,4112x + 0,0002; R² = 0,9785), dengan Qm rata-rata 5.000 mg g-1; KL sebesar 0,0001 L mg-1 dan RL sebesar 0,0002 (menguntungkan). Aplikasi biochar 25% tandan kosong kelapa sawit dan formulasi padatan dekanter basah 75% zat humat dari biokonversi limbah pabrik kelapa sawit, berpotensi mengurangi pencemaran/polusi glifosat pada lahan perkebunan kelapa sawit sebagai pembenah tanah dan mendukung pengelolaan limbah berkelanjutan.The increasing use of glyphosate containing herbicides raises environmental concerns. These herbicides are persistent environmental pollutants and may harm soil and aquatic ecosystems. Although previous studies have evaluated different adsorbents, the use of palm oil mill waste for glyphosate containment has not been thoroughly researched. This study attempts to fill this gap by turning palm oil mill waste into eco-friendly adsorbents: biochar and humic substances. This study seeks to identify the glyphosate adsorption characteristics of diverse palm oil waste formulations in order to determine the optimal formulation through an isothermal adsorption analysis. Two major materials were used in the batch equilibrium experiments: biochar created from empty palm fruit bunches (B-OPEFB) and humic substances derived from wet decanter solids (HS-WDS). Each of these adsorbents were used on their own, and in different combinations to test how well they retained glyphosate. The results revealed that the adsorption capacity of biochar is largely due to its carbonporous matrix, while humic substances contribute to the adsorption via chemical interactions that are facilitated by active functional groups. Out of all the combinations, the one containing 25% biochar and 75% humic substances achieved the best adsorption efficiencies. The adsorption behavior of this combination was best described by the Langmuir isotherm, with a strong correlation (R² > 0.97). This clearly demonstrates the effectiveness of waste palm oil mills as a soil amendmentto reduce glyphosate contamination. In addition, this waste transformation to active materials for environmental protection supports the practice of sustainable agriculture

The Potential of Adsorption Technology for Batik Wastewater Treatment: A Review
Full text linkThe Indonesian batik plays a crucial role in supporting the country\u27s economy. However, its production often leads to environmental problems. As sustainable development implies the need for economic benefits equally accessible by all people without compromising the environment for the future of the next generation, the sustainability of batik means that batik, as a cultural product, should be preserved, and its production can bring economic benefits without harming the environment. Therefore, environmental issues related to batik should be overcome. Studies addressing the problem of batik wastewater have been conducted; however, adsorption technology is gaining popularity due to the benefits it offers. This review examines the characteristics of batik wastewater, identifies existing batik wastewater treatment technologies, and evaluates the potential of adsorption technology for batik wastewater treatment. This literature review was conducted using Science Direct and Directory of Open Access Journals (DOAJ) search engines, which initially collected 78 articles, and finally, 58 articles were found to be suitable for the review. An Excel-based matrix was then created to analyze the literature manually. It is found that batik wastewater is usually alkaline; the Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS) usually exceed the quality standard regulated by the Indonesian government, and are usually non-biodegradable, as indicated by the low BOD/COD ratio. Adsorption is widely applied, economically feasible, and can be easily operated by batik entrepreneurs. The performance of this technology is best when combined with other processes
Analisis Keberlanjutan Pengusahaan Rumah Walet dalam Kontribusinya Pembangunan di Provinsi Banten
No full textSustainable development is development aimed at achieving a better quality of life. The sustainability of swiftlet bird nest (SBN) exports is influenced by the quality of swiftlet house production. Banten Province is a producer and supplier of high-quality SBN for export and local markets. Analysis of swiftlet house business sustainability encompasses three aspects: the ecological, economic, and social aspects. The sample consisted of thirty-eight (38) swiftlet houses in the coast, hills, and plains ecological areas located in the regencies of Banten Province. The analysis used was the RAPFISH (Rapid Appraisal for Fisheries) method which is an analysis tool or method based on Multidimensional-Scaling (MDS) through the R Software program. MDS is a statistical technique through multidimensional transformation into a lower dimension for measuring sustainability. The levels of sustainability on the coast, hills, and plains are 53.16%, 55.44%, and 56.94%, respectively. A value greater than or equal to 50% indicates a sustainable status; thus all these areas have a sustainable status. The determination of sensitive attributes was measured based on the priority order of the results of the MDS leverage analysis by observing the form of changes in the Root Mean Square (RMS). The greater the RMS value, the more significant the role of the attribute in influencing the sustainability of swiftlet house management. The highest RMS value impacting the success of swiftlet house management based on the ecological aspect is the threat of losses due to pests and disease outbreaks. This is also an economic factor with the highest value and is quite crucial. The existence of pests is closely related to the ecological aspect that leads to economic loss. The social aspects influencing sustainability are coordination between institutions and standardized public services. Coordination has the highest level of sensitivity which shows that synergy between institutions plays an important role in swiftlet house management. Good coordination can assist in the formulation of policies, implementation of effective regulations, and integrated supervision.Pembangunan berkelanjutan adalah pembangunan untuk mencapai kualitas hidup yang lebih baik.

Inter-species Competition Analysis Between Native Lowland Forest Trees to Optimize Land Rehabilitation Management in Bedegung Biodiversity Park, South Sumatra, Indonesia
Full text linkEffective CO2 sequestration (SC) in rehabilitated tropical forest depends heavily on species performance and competition dynamics. This study evaluates SC potential and interspecific competition of native lowland forest tree species in Bedegung Biodiversity Park, South Sumatra, Indonesia―an area rehabilitated since 2014 through collaboration between the South Sumatra Provincial Environmental Service, National Gas Company (PGN), and IPB University. Despite the rehabilitation efforts, early planting did not consider the planting distances (Lij), impacting tree density (Dx) and individual competition index (CIi)―factors directly influencing SC. From 2020 to 2023, monitoring of tree diameter, height, and Lij data collected within a 60 × 20 m permanent plot revealed a decline in Dx from 900 ind ha–1 in 2020 to 725 ind ha–1 in 2023, primarily due increased competition. The site’s average SC reached 69.91 tCO2 ha–1 y–1, lower than mature tropical forests due to stand age. Among all species, Bayur (Pterospermum javanicum) exhibited superior SC performance, sequestering 10.02 ± 6.98 tCO2 ind–1 y–1―well above the mean―and showing increased resilience, indicaed by 1/CIi from 0.62 to 4.38. These results highlight Bayur’s exceptional role in SC under competitive pressure. For enhanced SC outcomes, management interventions such as thinning, fertilization, remove the weeds, and removing dead trees are urgently recommended. Prioritizing species with high SC potential and adaptive performance, like Bayur, is essential for optimizing carbon gains in forest rehabilitation programs

Assessing Amdalnet’s Role in Digitalizing Environmental Approval in Indonesia:An Information System Success Model Approach
No full textStudi ini menilai keberhasilan Amdalnet menggunakan Model Keberhasilan Sistem Informasi DeLone dan McLean, dengan fokus pada enam dimensi: kualitas sistem, kualitas informasi, kualitas layanan, kegunaan, kepuasan pengguna, dan manfaat bersih. Survei online terstruktur dilakukan dengan 125 pengguna konsultan, pengulas, dan administrator yang menggunakan skala Likert dengan lima poin. Pemodelan Persamaan Struktural Kuadrat Terkecil Parsial digunakan untuk menganalisis data (PLS-SEM). Lima dari delapan hipotesis didukung. Khususnya, kualitas informasi tidak secara signifikan memengaruhi kepuasan pengguna atau penggunaan sistem, dan kepuasan pengguna tidak berdampak signifikan pada manfaat bersih. Temuan ini menunjukkan bahwa keterlibatan pengguna dalam platform digital wajib seperti Amdalnet lebih didorong oleh kepatuhan daripada nilai yang dirasakan. Studi ini menyoroti perlunya desain berorientasi pengguna dalam sistem informasi peraturan untuk meningkatkan kinerja dan legitimasi dalam tata kelola lingkungan.Amdalnet is a digital transformation for Indonesia’s environmental assessment process. It is very important for acceleration process, but there aren\u27t many in-depth studies that look at how well it works. This study evaluates the efficacy of Amdalnet through the DeLone and McLean Information System Success Model, which includes six evaluative criteria: system quality, information quality, service quality, use, user satisfaction, and the net benefits derived from the system. A structured online survey with 125 participants, consultants, reviewers, and system administrators, utilized a five-point Likert scale for data collection. After that, Partial Least Squares Structural Equation Modelling (PLS-SEM) was used to look at the data. The results showed that five of the eight hypotheses were supported by the empirical data. Both system quality and service quality significantly improved user satisfaction and use, and use was a strong predictor of net gains. On the other hand, the quality of the information didn\u27t have much of an effect on how people used the system or how satisfied they were with it, and user satisfaction didn\u27t have much of an effect on net benefits. These findings indicate that user engagement in mandatory digital platforms such as Amdalnet is predominantly driven by regulatory compliance requirements rather than the perceived advantages of the system. The study emphasizes the imperative for user-centric design in regulatory information systems to enhance both effectiveness and legitimacy in environmental governance. Policy implications are needed to improve the quality and legitimacy of Indonesia\u27s environmental approval process during digital transformation
