Abstract
Volcanic soils in Indonesia cover an area of about 5.4 million ha and around 2.7 million ha in Sumatra. The prolonged eruptions of Mt. Sinabung in North Sumatra from 2013 to today eject pyroclastic materials, which blanketed and altered the soil surface. As a result, volcanic soil formed from these pyroclastic deposits. This study aims to map the chemical properties of volcanic soils after the prolonged eruption of Mt. Sinabung from 2013-2020. Thirty-four soil samples were collected at a depth of 0-20 cm according to the grid sampling system with an interval of 1x1 km covering an area of about 4,500 ha. Regression kriging (RK) was applied to predict the soil’s chemical properties and distribution spatially. The soil samples were air dried, sieved, and analyzed to determine soil pH (H2O and KCl), available, potential and retention P, organic carbon, total nitrogen, cation exchange capacity (CEC), and exchangeable basic cations. Soil pH (H2O) ranges from very acidic to neutral (4.14-6.52) and very acidic to acidic pH (KCl) (3.89-5.26), low to very high available-P (3.46-382.01 ppm), potential-P very low to very high (3.76-230.26 mg 100g-1), P-retention is categorized as very high (90-99%). The organic Carbon range from low to very high (1.73-13.05%), low to high total nitrogen (0.13-0.60%), low to high cation exchange capacity (11.78-97.71 cmolc kg-1), and exchangeable base cations are categorized as high with K values (1.60-2.98 cmolc kg-1). Na (3.72-7.45 cmolc kg-1) and Mg (5.79-12.15 cmolc kg-1) were categorized as high and Ca very low (0.039-0.157 cmolc kg-1). The estimated area of soils with pH between 4 and 5 is about 424.85 ha, and soils with pH between 5 and 6 covered an area of approximately 3,964.81 ha. Our findings suggest that persistent eruptions of Mt. Sinabung supply new plant nutrition, which can enrich and increase soil fertility in the future.

Abstract
Mount Sinabung (at Karo Regency, North Sumatra) has been considered as an active volcano since 2010, and after three years of inactivity, the volcano’s activity resumed in 2013. The deposition of volcanic ash buried everything on the soil surface with various thicknesses. Volcanic ash is a valuable inorganic material and consists mostly of primary minerals. But with time, these materials can initiate carbon storage through the revegetation process. This study investigates carbon storage and sequestration in volcanic soils affected by the intermittent eruptions of Mt. Sinabung. A total of 34 soil samples were collected from areas of 3 to 7 km from the eruptive vent. The samples were analyzed to determine labile-C, very labile-C, total-C, Organic-C, non-crystalline-C, and metal complex-C fractions. Regression kriging (RK) was applied to spatially predict the carbon distribution. The results showed that the highest labile-C was 1.65% found in the Southeast slope and the lowest, 1.20%, in the Southern slope. The highest value of very labile-C was in the Southeast (1.20%), and the lowest was in the Northern (0.46%). The highest (11.66%) and lowest values (8.84%) of total C were in the Northeast and South slopes, respectively. The highest Organic-C value was detected 7.42% in the Northeast volcanic soils, and the lowest, 5.74%, is in the South slopes soil. The lowest non-crystalline- C was found in the soils of Northeast slope (0.60%), and the highest was in the Southeast (0.82%) soil. While the highest metal complex-C value was 0.88% in the Southeast, and the lowest is 0.36% in the soil of South slope. These data show that the highest carbon storage is parallel with the direction of the ash distribution, which tends to the Southeast side of Mt. Sinabung. The results of this study demonstrated that volcanic regions have a strong resilience capacity to bounce back after devastating natural hazards. Volcanic deposits interact with atmospheric water to initiate vegetation regrowth and create a carbon pool within their particles.

Abstract
The study was conducted to assess the site situation and propose solutions to develop the cropping area of pineapples in U Minh Thuong (UMT), Kien Giang province. The study used the Object-Based Image Analysis (OBIA) classification method to create a map of pineapple cropping in the U Minh Thuong area in 2016. Data on rainfall, soil type, temperature, and water reserves are inherited from the Department of Agriculture and Rural Development of Kien Giang Province and analyzed by the GIS method. Water irrigation in pineapple was estimated based on the formula of Mladen Todorovic, 2016 comparing freshwater reserves in the research region and irrigation water on pineapple, researched spatial distribution map of water response capacity for pineapple. The research results showed that the agricultural area in U Minh Thuong has natural conditions suitable for pineapple cultivation. The size of pineapple cultivation in this area was 4,387.29 ha, the largest in the Vinh Thuan district. The total freshwater reserve in the region varies, where the rainfall is, with the highest volume being 4,546.2 m3/ha (in September 2015) and the lowest 67.7 m3/ha (in March 2016). However, the U Minh Thuong region lacks water in the dry months from January 2016 to April 2016. The amount of water during this period is starved, with watering demand from 2,385 to 2,969 million m3 on the total cultivated area of pineapple. In contrast, the surplus water was quite high in the rainy season, about 2,252 - 27,257 million m3 in Vinh Thuan district in September 2015. The study proposes a solution to store water during the rainy season and use them effectively during the dry season. This solution is compatible with the main pineapple farming habit and model in U Minh Thuong, Kien Giang Province.
Technical and Vocational Education and Training toward Sustainable Development of Japan’s Aid Effectiveness for Industrial Human Resource Development in Lower Mekong Basin Countries

Published: April 2024

Abstract
The Official Development Assistance (ODA) is Japan’s salient foreign policy in the Lower Mekong Basin (LMB) Country, especially for industrial human resource development. Japan has established KOSEN, a Japanese engineering vocational education system in the region to promote the industrial acceleration agenda and the region’s economic, social development, and poverty reduction toward the 2030 Agenda of Sustainable Development Goals (SDGs). However, ODA is about more than giving and receiving; it is about actors and administration, including the vis-à-vis mutual benefit for both donor and recipient country, which becomes a debatable issue. This research intends to shed light on the efficacy of Japanese ODA toward LMB by applying the principles of the Paris Declaration on Aid Effectiveness (2005) and its impact on the Sustainable Development Goals (SDGs) attainment. A qualitative technique with a deductive approach was used to analyze the efficiency of Japan’s aid for KOSEN, including an in-depth interview with a purposive sampling technique of three key informants in this study. The study showed that the donor country predominantly adheres to the assistance ownership concept. Nonetheless, developing the KOSEN system as an assistance program in the area can contribute to the SDGs as hard tool mechanisms and KOSEN values as a soft mechanism related to the 2012 Global Agenda for Greening TVET.

Abstract
Tabanan Regency has various superior agricultural commodities, including coffee plantations and potential tourist attractions. Tabanan’s agriculture and tourism sectors have not been fully exploited, so the two have not yet run synergistically. Planning for an agro-technopark (ATP) is expected to create a production area based on agricultural technology, livestock and natural beauty. The ATP will leverage the potential of upstream and downstream agribusiness, infrastructure, and supporting services in coffee production, processing, and marketing. The research objective was to identify the sub-system of input, process, output, and development strategy of coffee ATP in Munduk Temu, Tabanan Regency. Data collection was carried out in two stages: secondary data collection with document study methods and primary data collection in the field using observation and interview methods. Data were analyzed using SWOT and strategic priority determination using Quantitative Strategic Planning Matrix (QSPM) analysis. The results showed that coffee cultivation with an integrated system supporting coffee ATP in Muduk Temu Tabanan fulfills input, process, and output requirements. Still, the quantity and quality of each sub-system need to be improved. The strategic position of coffee ATP development is in quadrant I (SO Strategy). Strategic priorities with the highest TAS value: 1) implementing technological innovations for managing pre-harvest and post-harvest Robusta coffee to support product diversification (st5 = TAS 6.94); 2) Policies from the local government in regulation and providing assistance to Subak Abian in supporting the development of ATP Coffee (st1= TAS 6.87); 3) Implementing crop-livestock integration to optimize resource potential (st3=TAS 6.86); 4) Implementing research results and studies based on superior products (st.4 = TAS 6.62). It is necessary to strengthen the institutional synergy between Village Owned Enterprises (Bumdes) managers, Subak Abian, and tourism stakeholders in improving the agricultural sector in synergy with the tourism sector.

The first is to collate/document the various perspectives of TEK from sustainable agriculture practices, ecological principles, water irrigation systems, and spiritual practices and values as part of the learning document. The second is to analyze the interdependence of the human and environmental systems in the context of the socio-ecological system framework for Subak TEK and its cultural sustainability. Third, to outline the potential effort to sustain Subak TEK by strengthening its adaptive capacity in the broader context of learning to strengthening the community based tourism planning. This study deploy the socio-ecological system, SES framework as the underlying theory and analysis and explore diverse initiatives to sustain Subak in the future. The study was conducted in conjunction with a sustainability leadership program which deployed an inter- and transdisciplinary approach of sustainability science that focuses on Subak as its case. Situational and content analysis from the workshop discussion notes is used to provide examples that describe diverse initiatives in tourism, agriculture, and education. The study found out that the SES framework of analysis in Subak TEK documented several core ritual activities, the interpretation of THK philosophy and its local wisdom and values which represent the interaction the social and natural system. Hence, demonstrate as a living monument with strong human institutions and nature interaction. Further, the Subak TEK has substantial community capital values that need to be strengthened by integration in the formal and non-formal education, the enhancement of the Tri Hita Karana (THK) awards and accreditation for tourism operators and hotels in the broader context of education for sustainable development framework as well as community-based tourism development planning. This initiative need to be supported by a community-based tourism by involving Pekaseh and youngsters in the current context of Bali community-based tourism.

Embedding sustainability education into hospitality, tourism, and events management curricula - a preliminary best practice model
Authors: Sulkowski N , Greenaway C , Vieira R 
Published: April 2024

Abstract
With over seventy percent of millennials preferring to spend disposable income on experiences rather than consumer goods, organizations operating in the tourism, hospitality, and events sectors are predicted to see increasing demand. Despite being recognized as a major contributor to economic activity, these sectors have been criticized for being a root cause of environmental degradation, acculturation, economic leakage, and migration. The recent collapse of international travel firms with far-reaching consequences for employees, suppliers, and destinations has highlighted the vulnerability of organizations to volatility in the business environment and calls for a reassessment of business and leadership models. Since the adoption of the United Nations Sustainable Development Goals in 2015, sustainability initiatives are becoming more embedded into corporate strategies with an increasing focus on the triple bottom line. Following the creation of the Global Reporting Initiative Standards and sector-specific standards, there is a growing expectation that organizations demonstrate accountability for their sustainability initiatives. In Western societies, this reflects a shift away from the liberalist notion of the “Theory of the Firm” towards the sustainability paradigm. The purpose of this exploratory paper is to propose a preliminary framework for embedding innovative sustainability education in undergraduate degree programs. The paper first reviews UK-based guidelines for sustainability education at the university level. It then proposes a framework for the development of a corresponding curriculum audit tool that assesses how comprehensively sustainability education is embedded into undergraduate curricula. The University of Gloucestershire’s degree programs in International Hospitality and Tourism Management and Event Management are used as case studies to demonstrate how an audit tool design based on relevant principles can be used in practice for assessing and enhancing sustainability education. The paper recommends the further development of the tool into a best practice model integrating graduate attributes, key learning outcomes and skills, and an appropriate learning and teaching infrastructure. Transferability across subjects and transnationally is identified as an area for further research.

Abstract
This research compares household organic waste compost results with the addition of local microorganism activators from banana peel and cassava peel waste with Effective Microorganisms (EM4). The composting method used is aerobic composting with the Takakura composting technique. This composting is carried out in 5 variations consisting of variation 1 (50% organic waste: 50% finished compost), variation 2 (50% organic waste: 50% finished compost: EM4), variation 3 (50% organic waste: 50% finished compost: local microorganism banana peel), variation 4 (50% organic waste: 50% compost made: local microorganism cassava peel), variation 5 (50% organic waste: 50% finished compost: local microorganism banana peel and cassava peel). The results showed that all variations of composting had met the maturity standard for parameters of temperature, pH, material reduction, texture, color, and smell and had met the SNI 19-7030-2004 standards. Analysis of all compost quality, including C-organic, nitrogen, C / N ratio, phosphorus, and potassium, has met SNI 19-7030-2004 standards. From 4 kg of raw material produced, solid compost ranges at 2.7-3 kg. The use of activators in the composting process can speed up the composting time by 8-12 days. Compost variations by scoring results in the compost consisting of 50% organic waste and 50% finished compost with 5 ml of local microorganism activator banana peel, and cassava peel is the best variation in compost maturity quality.

Abstract
Crude glycerol is a by-product of biodiesel production in which the number increases every year and is quite an expensive purification process to meet the technical standards required by consumer industries. To overcome this, it is important to find alternatives for crude glycerol utilization to increase the economic feasibility of the biodiesel industry. This study aimed to evaluate the technical feasibility of biogas production with the addition of crude glycerol from a Palm Oil Plant. The glycerol was introduced into 500mL Anaerobic Digester (AD) as a carbon source and energy source for the growth of methanogenic bacteria along with cow dung and Distilled Water with a ratio of 1:1. The addition of crude glycerol was 5% wt (GL5), 10% wt (GL10) dan 15% wt (GL15), and one control reactor without crude glycerol addition (GL0). AD was operated in a batch system at mesophilic conditions for 30 days. The highest biogas yield was obtained in the experimental set GL10 as much as 380 mL/g VS and was formed on the 3rd day but the highest percentage of methane gas (CH4) was obtained from the control set GL0 as much as 60.2%. In addition to the identification of bacteria, it was found that the type of Bacillus sp in the GL10 treatment was the most biogas producer, and based on the results of its bio-slurry analysis it could be used as organic fertilizer and soil improvement for agriculture and degraded soil.
Developing an innovative disaster resilience framework with universities as key agents – the value of consolidating international expertise
Authors: Sulkowski N , Towers N , Fuller M 
Published: April 2024

Abstract
Since the Covid-19 pandemic, the higher education sector has seen an expansion of universities’ expertise from being providers of education, research and knowledge transfer to providers of crisis response capacity for partners and stakeholders. Prior to that, nascent approaches towards delivering disaster mitigation and response capability through community training and volunteering were seen across universities located in areas prone to natural disasters. This leads to the purpose of the paper, which is to address initiatives required to enhance the role of the higher education sector in disaster resilience. Specifically, in relation to driving national policy-making and disaster management activities at the local level, high levels of decentralization prevent effective interventions by central government bodies. Based on an inductive approach, the methods used were informed by an initial fact-finding exercise and a series of roundtable discussions involving senior higher education and disaster resilience experts from across Indonesia and Europe. Building on the four theoretical perspectives, expert opinions then informed the conceptual development of an innovative and scalable disaster resilience framework. Within the higher education sector, this integrates conventional streams of university activity, such as curriculum development, research, innovation, knowledge transfer and networking, with a contextually adapted and appropriate disaster mitigation and response capability.

Abstract
Three-dimensional numerical investigations of vortex-induced vibration (VIV) of flexibly mounted rigid circular cylinder have been carried out using Open Source Field Operation And Manipulation (OpenFOAM). The cylinder is allowed to oscillate in both streamwise as well as cross-stream directions. The cylinder response and wake transition are studied by varying the mass damping parameter (

), ranging from 3 to 8, at a fixed value of Re equal to 350. Furthermore, the effect of Re, varied from 250 to 400, on VIV is illustrated for a fixed value of Ur
= 4.5. The response of the cylinder in terms of streamwise and cross-stream displacements is examined in and outside the lock-in regime. The cylinder trajectories are found to be influenced by the change in
