Abstract

The Giam Siak Kecil-Bukit Batu Biosphere Reserve was managed by zonation as a approach for multibenefitof management goals. This Bioshere Reserve has a fairly high carbon stock stored in its naturalpeat swamp forest ecosystems. Nevertheless, the condition of the peat swamp forest in the BiosphereGiam Siak Kecil-Bukit Batu currently has been destructed, especially in the buffer and transition zones.The threats of protected areas are not only coming from forest fire factors, but also from encroachmentand illegal logging. Therefore, it requires a recovery effort. This research aims to determine the survivalrate and to estimate the above ground biomass accumulation of the main tree species of peat swamp forestthat used to restore the burnt peat. The estimated total biomass accumulation on the surface was measured using allometric equations. Result of this research proved that Jelutung tree (Dyera polyphylla) has thebest survival rate among the trees (98%), while banana tree (Mezzettia parviflora) has lower survival rate( 35%). The highest total biomass accumulation was found in Jelutung (Dyera polyphylla) (499.015kg/ha/year, while the lowest total biomass accumulation was found in Meranti batu (Shorea uliginosa)(88.867 kg/ha/year). A total of nine pioneer species were identified i.e. Tenggek burung (Euodia sp),kayu ara (Ficus sp), mahang (Macaranga triloba), karet (Havea brasiliensis), sendayan (Scleriasumatrensis), alang-alang (Imperata cylindrica), senduduk (Melastoma malabathricum), paku-pakuan(Neprolepis hirsutula) and rumput teki (Cyperus rotundus). The total biomass accumulation of earlysuccession in all types of vegetation pioneer is 338,91 kg/ha.Key words: Above Ground Biomass Accumulation, restoration, vegetasion succession, burned peatland,Survival Rate.

Abstract

The universal health social security program in Indonesia began in 2014, and as of the present day, many people are now covered by it. However, many weaknesses in the system have been pointed out. Significantly, many people do not possess the necessary health cards to take advantage of the program due to the complicated process one must go through in order to obtain them. Even now, 60 million people have not joined the program. Many people do not rely solely on the universal social security program but may be supported primarily or additionally by the vernacular care system, whereby support is provided by their family, friends and community. This study intends to understand and analyze the vernacular care system found in rural West Java, Indonesia, with particular focus being given to the elderly’s engagement with it. This study is mainly based on field work that surveyed 64 households with a socio-economic household survey being conducted alongside in-depth interviews with elderly people who received medical check-ups in 2003. This study shows the importance of care; not only that which is provided by the children of elderly parents, but also the grandchildren. In cases where children migrate from their family homes, elderly family members are supported not only through remittance, but also by having their grandchildren live with them. Otherwise, the characteristics of the informal sector occupations enable people to continue living in and around the village that their families are based so that their children, children-in-law, and grandchildren can care for the elderly.

Abstract

Biodegradable foam has been vastly developed to replace polystyrene foam. However, its water absorption capacity has become a significant obstacle to being used in food packaging. Therefore, this study aims to assess the effect of incorporating natural waxes as a coating material in producing biodegradable foams. The four natural waxes are soy wax, candelilla wax, beeswax, and carnauba wax. The biodegradable foams were fabricated with cassava starch and rice straw as natural fiber sources using a thermal pressing machine. The Meyer-Rod coating method was adopted to produce high contact angle and highwater resistance starch-based biodegradable foams. Water absorption analysis was performed according to the Cobb60, and water solubility analysis was conducted based on International Standardization for Organization 10634:2018 procedure. The result shows that the surface modification of starch-based biodegradable foams with natural waxes significantly improved water absorbency and water solubility. Moreover, it is demonstrated that the use of carnauba wax had the highest decrease of Cobb60 index of 1.5 g/m2 and the lowest water solubility of 2% after carrying water for 90 min. This study concludes that the utilization of natural waxes a as a coating material for starch-based biodegradable foam could replace conventional polystyrene foam for food packaging industry.

Abstract

The payment for ecosystem services (PES) scheme in the Cidanau Watershed, Banten Province, Indonesia has not yet quantified and reviewed its livelihood impacts on its providers after two decades of implementation. Therefore, this study maps the livelihood sustainability of PES farmers and non-PES farmers in the Cidanau Watershed using capital indexes based on the five livelihood capital assets of the DFID’s sustainable livelihood framework. The research used a quantitative method to formulate the livelihood capital indexes (LCI) as approximates to the subjects’ livelihood sustainability based on their livelihood information and draws implications from the results thereof. A total of 168 agroforestry farmers both from PES and non-PES groups were interviewed across 12 villages in the upstream area. The results show that both PES and non-PES groups share the same pattern of capital assets sustainability with the PES group having a slightly higher human capital asset. The overall LCI calculated for the PES and non-PES groups are 0.445 and 0.48, respectively. The livelihood of both groups is deemed as not yet sustainable. The farmers would have to develop their financial and human assets to attain more sustainable livelihoods and prepare themselves for adopting new types of PES in the future.

Abstract

Peatlands conversion to dryland for plantation has caused environmental havoc and is more prone to natural disasters in Indonesia. Community engagements under village administration should be the main strategy for supporting peatlands restoration. Since the new law on villages was enacted in 2014, the village has gained authority and delegated responsibilities from the upper-level government to make rural development decisions in various sectors, including those connected to environmental management, such as peatland restoration. The recognition of authority is followed by the transfer of significant funds, called village funds, from the central government as a form of commitment to undertake the village law. Currently, applied regulations allow community engagement to utilize the village fund for supporting peatland restoration. This study investigated the community's perceptions of village fund utilization for peatland restoration through in-depth interviews and questionnaires with site-level stakeholders that influence village budget allocation-related policies. The investigated aspects included village budgeting and development planning mechanism, the capacity of the community, and rules of district government in supervising the villages. Based on our findings, the identified challenges include the absence of environmental aspects as a part of village development pillars for developing village planning and budgeting, lack of community's environmental-economical nexus knowledge, and lack of district government in supervising village fund utilization and management at the site-level. However, the opportunities to direct the village fund utilization for peatlands restoration are widely open by strengthening the roles of district government to improve village fund governance at the site level.

Abstract

Indonesia has Karst areas spread throughout almost the entire archipelago. The Klapanunggal Karst region has been officially designated as a Karst Landscape Area, to emphasize its protected status, in alignment with governmental endeavors aimed at ensuring the long-term preservation of the ecological and human-related significance of this karst ecosystem. The aim of this research is to perform an economic valuation of the Klapanunggal Karst region using the Travel Cost Method. The research conducted intensive field observations within the Klapanunggal Karst area and administered well-structured questionnaires to a sample size of 109 respondents from visitor Klapanunggal Karst region. Base on observations and field data, the Klapanunggal Karst region was partitioned into four distinctive zones. Zone 1 is location within an industrial limestone mining permit area, thus vulnerable to the imminent threat of industrial mining activities. Zone 2 is situated within the precincts of the Klapanunggal KBAK. Zone 3 has been transformed from a former mining site into a tourist destination. Lastly, Zone 4 has earned the coveted status of a tourist village. Subsequently, based on the economic valuation calculations, the Klapanunggal Karst region was found to have an annual economic value of Rp. 4,156,219,112.40, with a visitation rate of 0.006% of the total tourists visiting Bogor Regency. The researchers also recommend the development of tourism in the Klapanunggal Karst region as a means of enhancing the local economy, as well as ensuring the protection and sustainability of the Klapanunggal Karst area, including other critical aspects like water resources and ecosystem values.

Abstract

The world today is highly interconnected. To address the manpower shortage in Japan and the surplus in Indonesia 30 years ago, both countries developed an internship program, "Ginou Jisshu." During the internship, participants with Indonesian culture-based individual characteristics are exposed to Japanese work culture. This study aimed to investigate how interns' individual characteristics and their assimilation of Japanese work culture improve their competency and competitiveness, considering self-efficacy as a moderating factor. Using a quantitative research method, data from 400 internship alumni across 38 provinces in Indonesia were collected through Google Form questionnaires and analyzed using PLS-SEM. Out of 10 proposed hypotheses, all direct effect hypotheses were accepted, and 3 of the moderation hypotheses were accepted, while 2 were rejected. This study introduces a novel paradigm where any positive effect, regardless of statistical significance, is considered beneficial. It suggests that resolving issues, even minor ones, can amplify positive effects and mitigate negative effects. The findings reveal that individual characteristics and Japanese work culture positively affect competency and competitiveness, and competency further enhances competitiveness. Self-efficacy strengthens the impact of individual characteristics and Japanese work culture on competency, as well as the impact of Japanese work culture and competency on individual competitiveness. However, it weakens the effect of individual characteristics and competency on individual competitiveness.

Abstract

The use of masks is recommended to reduce the risk of widespread spread of the Covid-19 virus, but because of its use in high quantities in a short time, it has an impact on the high waste of disposable masks. The problem of high waste of masks that is not accompanied by good management is it has the potential to pollute the environment and disposable masks are included in the type of hazardous medical waste so that they require special waste management. The purpose of this study is to analyze the relationship between the sociodemographic characteristics of the people of DKI Jakarta and the Willingness to Pay (WTP) for disposable mask waste management to determine the WTP price for disposable mask waste management. The survey was conducted in DKI Jakarta Province by distributing questionnaires and obtained a total sample of 356 respondents. Furthermore, the analysis method used, the first is logistic regression analysis to determine the variables of sociodemographic characteristics that affect individual WTP. The next analysis method is to calculate WTP using the Contingent Valuation Method (CVM) and the question model with the Double Bounded dichotomous method. Based on the results, it is known that the dependent variables that can increase the WTP value are income (Δ+ 23.6%, p ≤ 0.05), type of healing treatment (Δ+ 100%, p ≤ 0.1), and knowledge (Δ+ 125.9%, p ≤ 0.01), where a value of Rp 28,578 is ideal for the cost of managing disposable mask waste.

Abstract

Perempuan memiliki beragam alternatif produk untuk menjaga kebersihan menstruasi, termasuk pembalut sekali pakai, pembalut kain, dan cawan menstruasi. Meskipun demikian, pembuangan yang benar terhadap limbah sanitasi telah menjadi kekhawatiran baru dalam pengelolaan limbah, menyebabkan dampak lingkungan yang signifikan dan berkontribusi pada polusi ketika tidak dibuang dengan benar. Penelitian ini bertujuan untuk mengetahui tingkat penerimaan terkait pembalut sekali pakai, pembalut kain, dan cawan menstruasi di kalangan perempuan di DKI Jakarta, Indonesia. Data yang dikumpulkan melalui penyebaran kuesioner, Uji Korelasi Kendall’s Tau-b, dan analisis akar penyebab digunakan untuk menganalisis data. Temuan dari penelitian ini menunjukkan bahwa konsumen, meskipun sebagian besar lebih memilih pembalut sekali pakai, memberikan peluang untuk adopsi produk yang berkelanjutan karena hubungan kompleks antara preferensi, penerimaan, pengetahuan, dan kesiapan membayar. Strategi yang melibatkan implementasi tindakan korektif yang memprioritaskan edukasi berfokus pada konsumen, sangat penting untuk mempromosikan dan meningkatkan adopsi produk menstruasi yang lebih berkelanjutan.

Abstract

Corruption in Indonesia's natural resource sector is a significant issue with far-reaching consequences for environmental sustainability. Despite the detrimental effects of corrupt practices on the environment, law enforcement penalties for corruption often fail to compensate for their environmental impact. The aim of the study is to explore how the use of Environmental Impact Assessments (EIAs) strengthens law enforcement efforts and increase penalties for corrupt practices in Indonesia's natural resource sector. The method used is to collect and analyze regulations, policies, and corruption study cases to examine the relationship between EIA and corruption penalties. The results showed that EIA can help corruption cases investigation and corruption cases involving EIA receive heavier penalties. This study concluded that the Indonesian government needs to reformulate its law enforcement approach by incorporating EIA into corruption investigations and using more severe penalties to deter corruption in the natural resource sector.
