This study sought to examine the food consumption experiences of local cuisine among Gen-Z tourists in Indonesia. The SEM analysis was employed to define the consumption value, experiential value, and social media influencer to attitude towards local food and food destination image which lead to behavioural intention. A total of 340 respondents were selected to get a comprehensive insight from the young-adult generation. This study found that health value, emotional value and interaction value, and social media interaction have a positive relationship to the food destination image. Meanwhile, the attitude was affected by emotional values and social media. Both food destination image and attitude have a significant impact on behavioural intention. This study contributes to gastronomic, marketing, and hospitality literature in the context of local cuisine. Moreover, practical contributions are discussed to gain focus on resource development.

The design of the gas distribution for small-demand power plants located on remote islands is logistically challenging. The use of small-scale liquefied natural gas (LNG) vessels can be an option for these logistic problems. This paper aims to conduct a techno-economic analysis of using small-scale LNG vessels for gas distribution to the power plants that are spread across different islands. Route optimisation has been conducted using the capacitated vehicle routing problem method. The ship's principal dimensions were determined using the aspect ratio from a linear regression of existing small-scale LNG vessels. As a case study, the gas demands for a gas power plant in eastern Indonesia were analysed into four distribution clusters. The results of the techno-economic analysis showed that the four distribution clusters have different characteristics regarding the LNG requirements, location characteristics and ship specifications. The capacity of small-scale LNG vessels feasible in terms of technical aspects varies from 2500, 5000, to > 10,000 m3 with variations in the ship speed depending on the location of the power plants. The amount of cargo requested and the shipping distance was affected to the cost of LNG transportation. The economic assessment proposes that the feasible investment by considering small-scale LNG cargo distribution, from the case study shows that with a ship capacity of 5000 m3 feasible margin rate is ≥ 3 USD/metric million British thermal units with an internal rate of return of 10% and estimated payback period is less than 15 years.

We implemented Water Safety Plans (WSPs) program at previous work due to poor of water quality in the coastal area of Semarang, Indonesia. The aimed of the research was to evaluate water quality before and after implementation of WSPs program in Bandarharjo village, Semarang city. This was an experimental design with steps for implementations of WSPs program adopted the guidelines and tools of the World Health Organization. Numbered 80 samples before and after implementation of WSPs and fulfilled by purposive sampling technique. The main parameters of drinking water were total coliform with MPN method, turbidity with turbidity meter, salinity and pH with potentiometer instrument. Data were analyzed using Wilcoxon match-paired signed-rank test at α = 5%. Bacteriological quality of drinking water in Bandarharjo village has increased 17.5% after implementation of WSPs program. There were significant difference between total coliform (p = 0.016), salinity (p = 0.028), and turbidity (p < 0.001) before and after implementation of WSPs. Implementation of WSPs program has improved water quality, however regularly monitoring of the water supply system and bacteriological treatment are needed. [ABSTRACT FROM AUTHOR]

Tempeh is a common food in Indonesia, produced by fungal fermentation of soybeans using Rhizopus sp., as well as Aspergillus oryzae, for inoculation. Analogously, for economic reasons, mixtures of maize and soybeans are used for the production of so-called tempeh-like products. For maize, a contamination with the mycoestrogen zearalenone (ZEN) has been frequently reported. ZEN is a mycotoxin which is known to be metabolized by Rhizopus and Aspergillus species. Consequently, this study focused on the ZEN transformation during tempeh fermentation. Five fungal strains of the genera Rhizopus and Aspergillus, isolated from fresh Indonesian tempeh and authentic Indonesian inocula, were utilized for tempeh manufacturing from a maize/soybean mixture (30:70) at laboratory-scale. Furthermore, comparable tempeh-like products obtained from Indonesian markets were analyzed. Results from the HPLC-MS/MS analyses show that ZEN is intensely transformed into its metabolites α-zearalenol (α-ZEL), ZEN-14-sulfate, α-ZEL-sulfate, ZEN-14-glucoside, and ZEN-16-glucoside in tempeh production. α-ZEL, being significantly more toxic than ZEN, was the main metabolite in most of the Rhizopus incubations, while in Aspergillus oryzae fermentations ZEN-14-sulfate was predominantly formed. Additionally, two of the 14 authentic samples were contaminated with ZEN, α-ZEL and ZEN-14-sulfate, and in two further samples, ZEN and α-ZEL, were determined. Consequently, tempeh fermentation of ZEN-contaminated maize/soybean mixture may lead to toxification of the food item by formation of the reductive ZEN metabolite, α-ZEL, under model as well as authentic conditions.
