Purpose – This paper aims to detect or identify the presence of hydrocarbon infiltration on sampling point in the Rambe River area according to the obtained VOCs and the adsorbed SVOCs.

Design/Methodology/Approach – The Gore-sorber method has been used to capture volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) as indicators of subsurface hydrocarbon generation and entrapment. This method is usually used in environmental surveys for the oil investigations in certain areas for surface survey screening, designed to collect a broad range of VOCs and (SVOCs) at lower concentrations, quickly and inexpensively. The results also indicated a general correlation between the GORE-SORBER and reference method data. The research was conducted in Rambe River Village, Tebing Tinggi sub-district of Tanjung Jabung Barat district, Jambi Province Indonesia. The collection of the Gore-Sorber modules were analyzed using a gas chromatography-mass spectrometer thermal desorption (GC/MS).

Findings – The results showed that from all sampling points in Tebing Tinggi areas, the dominant components detected are carbonyl sulphide, dimethyl sulfide, ethane, propane, butane, 2-methyl butane, pentane, and carbon sulfide with carbon chain in the range C2-C5. These hydrocarbon gases (C1-C4) which may be from thermogenic or microbial processes. The highest concentrations of carbonyl sulfide were 392.67 ng and dimethyl disulfide 261.90 ng.

Originality/Value – In addition to estimate and predict the petroleum formation, this article provides information about the presence of oil fields in the area of the Sungai Rambe Village

Purpose – This work aims to study the treatment of adsorbant on the increasing liquid hydrocarbon quality produced by pyrolysis low density polyethylene (LDPE) plastic waste at low temperature. The hydrocarbon distribution, physicochemical properties and emission test were also studied due to its application in internal combustion engine. This research uses pure Calcium carbonate (CaCO₃) and pure activated carbon as adsorbant, LDPE type clear plastic samples with control variable that is solar gas station.

Design/Methodology/Approach – LDPE plastic waste of 10 kg were vaporized in the thermal cracking batch reactor using LPG 12 kg as fuel at range temperature from 100 to 300°C and condensed into liquid hydrocarbon. Furthermore, this product was treated with the mixed CaCO₃ and activated carbon as adsorbants to decrease contaminant material.

Findings – GC-MS identified the presence of carbon chain in the range of C6–C44 with 24.24% of hydrocarbon compounds in the liquid. They are similar to diesel (C6–C14). The 30% of liquid yields were found at operating temperature of 300°C. The calorific value of liquid was 46.021 MJ/Kg. This value was 5.07% higher than diesel as control.

Originality/Value – Hydrocarbon compounds in liquid produced by thermal cracking at a low temperature was similar to liquid from a catalytic process.

Food fraud as intentional deception for economic gain relies on a low-tech food value chain, that applies a ‘paper-and-pencil approach’, unable to provide reliable and trusted data about food products, accompanied processes/activities and actors involved. Such approach has created the information asymmetry that leads to erosion of stakeholders and consumers trust, which in turn discourages cooperation within the food chain by damaging its ability to decrease uncertainty and capability to provide authentic, nutritional, accessible and affordable food for all. Lack of holistic approach, focus on stand-alone measures, lack of proactive measures and undermined role of customers have been major factors behind weaknesses of current anti-fraud measures system. Thus, the process of strong and fast digitalisation enabled by the new emerging technology called Industry 4.0 is a way to provide a shift from food fraud detection to efficient prevention. Therefore, the objective of this chapter is to shed light on current challenges and opportunities associated with Industry 4.0 technology enablers' guardian role in food fraud prevention with the hope to inform future researchers, experts and decision-makers about opportunities opened up by transforming to new cyber-physical-social ecosystem, or better to say ‘self-thinking’ food value chain whose foundations are already under development. The systematic literature network analysis is applied to fulfil the stated objective. Digitalisation and Industry 4.0 can be used to develop a system that is cost effective and ensures data integrity and prevents tampering and single point failure through offering fault tolerance, immutability, trust, transparency and full traceability of the stored transaction records to all agri-food value chain partners. In addition, such approach lays a foundation for adopting new business models, strengthening food chain resilience, sustainability and innovation capacity.

Purpose: In the experience economy, the main challenge for museums is not only to attract visitors but also to preserve artworks. Given this circumstance, this chapter aims to offer an overview of how these cultural organisations have emerged as labs of the future culture, where all kind of technological experiments are tested so as to fulfil their mission.

Design/methodology/approach: This chapter is based on extensive literature review on issues related to robots, artificial intelligence and service automation (RAISA) in the museum sector. Examples illustrate the role of technology in the experience design and preservation of cultural resources.

Findings: 1) A chronological framework of museums’ orientations is established to understand the evolution toward the technology-driven present period. 2) Robots, artificial intelligence and service automation have a meaningful contribution to make in guaranteeing visitor arrivals. 3) This technological phase requires a tourism workforce with new skills.

Research limitations/implications: Few academic studies concerning to the use of robots, artificial intelligence and service automation in the museum sector were found. Hence, more empirical studies are required to completely corroborate the chapter’s suggestions.

Practical implications: An enlightening path for the service design of multisensory and participatory is proposed, as a useful guide for heritage managers, marketing practitioners and tourism planners.

Originality/value: Museum management has been always receiving the attention of managers, policymakers, scholars, among others. Insights of how technology enhances heritage preservation and the improvement of museum services throughout numerous examples can direct them to increase knowledge and adopt these practices.

One common view of technology is as knowledge. “Defining technology as knowledge has important implications for how we comprehend technology in the making because it conceivably includes not only what exists, but what individuals believe is possible” (Garud & Rappa, 1994, p. 346). If “all knowledge and all knowledge-claims are to be treated as being socially constructed” (Pinch & Bijker, 1984, p. 401), the importance of discourse to such a view of technology is clear.

In the year 2001, the Risk Assessment Pilot Program was implemented in Argentina with the aims of establishing a systematic manner of assessing risk for violent recidivism in conditional release candidates and contributing to the design of intervention programs that help to reduce the criminal recidivism rate. The baseline assessment showed that conditional release candidates had a high-risk profile: 72.5% had severe or moderate substance abuse problems; 62% had failed in previous probation, conditional release or discharge from a mental institution; 85% had serious or moderate employment problems before incarceration. Individuals who were substance abusers were incorporated to the Drug Abuse Biochemical Control Program. Variations in dynamic factors were assessed with conditionally released subjects. Some encouraging results were obtained through December 2003 and their initial impact on judicial and penitentiary institutions is already seen.
