Abstract
Chaoshan Depression is a Mesozoic residual depression in the northeast of the South China Sea. It mainly develops two sets of Source rock, i.e., upper Triassic lower Jurassic shallow marine bathyal facies mudstone, lower Jurassic shallow marine shelf facies mudstone, upper Jurassic shallow marine reef limestone, and upper Jurassic basin floor fan sandstone, with good oil-gas exploration potential. It has gone through six tectonic evolution stages in the Mesozoic and Cenozoic, with strong uplift and denudation, developed fault structures, complex hydrocarbon accumulation conditions, and unknown hydrocarbon distribution laws. Analysing the Carbon Isotope Values of Acidolysis Hydrocarbons and Methane in Seabed Sediments through Detection δ 13C (‰) prediction of favourable oil-gas exploration zones, oil-gas traps, and types of oil-gas reservoirs is a fast and effective method for oil and gas geochemical exploration. The first detection of trace amounts of light and heavy hydrocarbon components and methane carbon isotope values in marine surface sediments at 200 stations in the Chaoshan Depression based on acidolysis δ 13C (‰), quantitative analysis of abundance and structural anomalies of light and heavy hydrocarbons using gas chromatography mass spectrometry, and quantitative analysis of carbon isotope values of light, heavy, and methane using the Kriging method δ13C (‰) plane distribution characteristics delineate two comprehensive anomaly zones for oil-gas exploration in the northeast and southwest of the Chaoshan Depression. CS depression is a petroleum depression, and DS-A structure is an oil gas structure.

Published: January 2024

Abstract
An imaging method that utilizes a scintillator plate
combined with a magnifying unit and a cooled electron multiplying
charge-coupled device (EM-CCD) camera shows promise for obtaining
high-resolution trajectory images. However, it is not yet clear
whether the ranges of the trajectory images change with the energy
of the alpha particles. Additionally, it remains unclear whether the
intensity of the trajectory images is affected by the energy of the
alpha particles. To address these questions in our trajectory
imaging research, we conducted experiments to capture trajectory
images of alpha particles with varying energy levels. To generate
alpha particles with different energies, we modulated the energy
using an americium-241 (Am-241) source covered with varying numbers
of Mylar films. With this alpha source and imaging system, we
successfully captured trajectory images with different alpha
particle energies and were able to assess the ranges and intensities
of these trajectories at various energy levels. The estimated ranges
from the measured images with different alpha particle energies
closely matched the results obtained through simulations. However,
it's worth noting that the light output, as evaluated for the
measured trajectory images, was slightly lower than the simulated
results at lower energy levels probably due to the
non-proportionality of the GAGG plate with respect to alpha particle
energies.

Published: January 2024

Abstract
The current research is intended to optimize the formulation of bionanocomposite films produced from polyvinyl alcohol by adding glycerol (4–8%) and cellulose nanocrystals extracted from pineapple crown leaf (3–7%). The interaction between the bionanocomposite films characteristic, such as thickness, tensile strength, and elongation are determined using a response surface methodology with a central composite design. To show the practical relevance of the prediction model, the optimized bionanocomposite film composition required additional validation. Adding glycerol at 4% and cellulose nanocrystal at 3.52% was determined to be the film’s optimum parameters. Improved mechanical properties with a low thickness value and high elongation were found in the enhanced film formulation. The findings showed that an optimized bionanocomposite film formulation based on polyvinyl alcohol with glycerol and cellulose nanocrystals from pineapple crown leaves provided good model validation and could be utilized optimally in the food packaging application.

Abstract
Coadjuvants, such as CaCO3, are essential to improve the effectiveness of the extraction process. This study aimed to assess how the addition of CaCO3 as a coadjuvant impacts the yield of avocado oil through the process of solvent extraction using hexane. Response surface methodology was employed to optimize parameters influencing oil yield during solvent extraction. A Box-Behnken design with three factors and three levels was utilized for the optimization process. Factors involved are, concentration of CaCO3 (1, 1.5, 2%), extraction time (30, 60, 90 min), and temperature of extraction (25, 35, 45 °C). The linear model provided the most accurate fit to the experimental data, substantiated by the highest determination coefficient (R2) value. The experiment showed that the highest yield of avocado oil, reaching 48.06%, was obtained by extracting it under the specified conditions: a CaCO3 concentration of 1.92%, an extraction time of 89.85 minutes, and a temperature of 43 °C. The extraction yield of 48.77±0.14% obtained from the experiments using optimized conditions.

Published: January 2024

Abstract
Climate change caused by global warming, which is characterized by increasing temperatures on the earth’s surface, is the biggest problem in the world today. This study attempts to examine how local climate change has affected the characteristics of rainfall in Aceh Besar District, which is situated in the far north of Indonesia’s Sumatra Island. 2001 was assumed to be the onset of local climate change in the region. Using EasyFit, probability distribution that best fits the rainfall data during the pre- and post-onset of climate change is chosen. The results indicated that the annual rainfall amount has increased over the past decade. The probability of receiving an annual total rainfall exceeding the long-term average (1700 mm) has increased significantly after the local climate change. Meanwhile, although the lowest and highest amounts of annual maximum daily rainfall for pre- and post-onset periods remain the same, the frequency of the maximum daily rainfall in a year greater than 140 mm/day was doubled during the post-onset period. Consequently, local climate change has increased the expected amount of annual maximum daily rainfall for return periods of 2, 5, and 10 years.

Based on the results of the research conducted, it can be seen that the criteria that are the main priority is Flavour with a priority value of 38%, Alternative results with the highest priority value on Flavour criteria are alternative I with a priority value of 18.9%, Roasting level treatment and Grinding level have a significant effect on panelist assessment on all criteria that have been set.
Medium modification for the growth of Rhizopus oligosporus and Acetobacter xylinum as starter cultures in the production of biofoam, environmentally friendly packaging
Authors: Yulia M , Yunita D , Indarti E , Muliani S , Lahmer R A 
Published: January 2024

Abstract

Acetobacter xylinum was injected to reduce the porosity value and water absorption of biofoam which was made using bagasse and Rhizopus oligosporus. However, data interpretation of the total counts of both microbes could be misleading. Therefore, the aim of this research was to create a specific medium for the growth of both microbes. The research was conducted in three stages. In the first stage, soybean flour was added into bagasse to produce depithed bagasse at different ratios (1:1 and 1:1.5) for use in the growth of Rhizopus oligosporus. In the second stage, urea and bean sprouts extract were used to grow Acetobacter xylinum. Finally, modified media was used to grow both starters. The results showed that the total plate counts of Rhizopus oligosporus on bagasse medium was quite similar with the depithed bagasse ranging from 4.58 to 4.87 log cfu/gram. The addition of bean sprouts extract had an absorbance yield of 0.162 while the addition of urea had an absorbance value of 0.085. Therefore, bagasse and soybean flour (in the ratio of 1:1.5) and bean sprouts extract are recommended to grow both starters because of the efficiency process and the highest absorbance yield.

Published: January 2024

Abstract
Local business actors play an important role in realizing sustainable ecotourism through good business governance. Various strengthening actions are needed, one of which is in terms of environmental costs in business development. This research aims to analyze how business behavior can influence community participation, social capital, economic costs and environmental costs in sustainable ecotourism management efforts in Padusan Village, Pacet District, Mojokerto Regency. Local business behavior through community participation can shape the social capital that occurs in Padusan Village. This research on business behavior uses quantitative descriptive methods with SEM-PLS analysis. A total of 178 questionnaires were distributed to the community and ecotourism business owners in Padusan Village. The research results show that business behavior has a significant effect on community participation, social capital, environmental costs, and economic costs both directly and indirectly. Ecotourism business behavior has an indirect negative influence on environmental costs through the mediating variable of economic costs. Apart from that, business behavior also has a significant influence on social capital, both directly and indirectly. The indirect positive influence of ecotourism business behavior on social capital occurs through the participation and involvement of local communities in business activities. Based on the research results, it shows that ecotourism business behavior has an impact on the environmental costs that must be incurred as well as social capital in local community participation. So business people need to implement good environmental control strategies by adopting Environmental, Social, and Governance (ESG) measures to achieve sustainable ecotourism goals.
Tropical Fruit Waste Management: Developing Pectin-based Biopolymer from Durian Rind (Durio zibethinus)

Published: January 2024

Abstract
Durian (Durio zibethinus) is a popular native tropical fruit and is largely produced in Southeast Asia. In Indonesia, 1.71 million metric tons of durian were produced in 2022. However, this high production may lead to organic waste issues due to the large amount of durian rind generation. About 60 – 75% of the durian is the rind, which is mostly discarded, hard to be decomposed, and not utilized optimally. Meanwhile, the durian rind poses as a potential reservoir containing high concentrations of cellulose and pectin. Therefore, this research aimed to (1) extract pectin content from durian rind and (2) synthesize and characterize pectin-based biopolymer films. First, the pectin was extracted from dried durian rind powder using acid extraction and alcoholic precipitation methods. Then, biopolymer synthesis was done by mixing formulations of pectin, chitosan, ethylene glycol, and glycerol solutions to form thin films. About 0.13 – 0.71 g of pectin (0.46% of the pectin yield) was extracted per 100 g of dried durian rind powder. The FTIR spectroscopy results of the extracted pectin confirmed the presence of the O - H groups at 3327.83 cm-1, which indicated the pyranose ring, the main characteristic of pectin. Pectin-based biopolymer films were produced with thickness, transparency, and tensile strength of 0.01 – 0.07 mm, 7.40 - 40.50, and 1.26 – 2.69 MPa, respectively. The findings of the soil burial degradation test for biodegradability showed that the biopolymer experienced weight loss of up to 62% in 14 days. Considering the potential utilization of the durian rind for developing biopolymers as value-added bioproducts from agricultural biomass, tropical fruit waste management should be done properly in the future. This also can be offered as one of the alternative solutions for plastic substitution with proper development in the future.

Abstract
Yogyakarta International Airport (YIA) and supporting infrastructure in Kulon Progo Regency, Yogyakarta, aims to encourage economic growth and support the tourism, industrial, trade, and education sectors. This study aimed to monitor the pattern of changes in land use that occurred after the construction of the YIA, especially in the agricultural sector. The quantitative method with spatial analysis through overlay was chosen to produce multitemporal land use change maps (2018 and 2022). The preparation of the land use map was carried out through the visual interpretation of Pleiades satellite imagery with a spatial resolution of 0.5 m. The results of the study showed that there had been a very massive change in land use in the Temon Sub-district, especially in relation to the decrease in the area of agricultural land. The impact of the construction of the airport and its supporting infrastructure in the Temon Sub-district had resulted in a reduction of 21.24 hectares of rice fields. Land use from agricultural land had mostly changed to the construction of YIA, infrastructure development, and built-up land (settlements, hotels, restaurants, trade, and services). The increasingly massive decrease in the area of agricultural in the study area needs attention from the government so that the existence of agricultural land remains sustainable, considering that most people depend on the agricultural sector for their lives.
