Abstract

Nature tourism in Mandailing Natal Regency, North Sumatra has promising potential. Statistical data shows an increase in local tourist visits of 6,274 people in the 2023-2024 period. This increase has a positive impact on community and government income, but has the potential to have a negative impact on ecological aspects if it exceeds the carrying capacity of the area. Therefore, the strategy for developing the area is an important factor in realizing sustainable tourism activities. This study was conducted in September-October 2024 with the aim of analyzing the strategy for developing sustainable tourism areas. Data collection was carried out to identify the carrying capacity of each tourist attraction using a SWOT (Strength-Weakness-Opportunities-Threats) analysis through interviews with relevant stakeholders. The results of the carrying capacity analysis show that this area is still able to accommodate tourist activities. The main strategy for sustainable development recommended is optimizing the area by expanding areas that have the potential for beautiful scenery as the main attraction, as well as improving supporting facilities and infrastructure in the future.

Abstract

This study aims to analyse the implementation of the Mining Safety Management System (SMKP) in the andesite quarry crushing area of PT. X, Subang Regency, West Java. The study uses a descriptive mixed methods approach that combines direct observation, structured interviews, and questionnaire surveys of workers in the crusher area using purposive sampling. The data were analysed using the Miles & Huberman model for qualitative data and descriptive statistics for quantitative data, with triangulation for validation of the results. The results showed that the implementation of SMKP at PT. X was still suboptimal. The overall criterion fulfilment rate reached 54.74% of the maximum total of 292 points, with significant variations between elements. The implementation element showed the best performance (54.31%), followed by organisation and personnel (54.55%), and monitoring and evaluation (60.42%). Conversely, three critical elements showed alarming conditions: documentation (33.33%), planning (37.93%), and management review (46.15%). This imbalance indicates a weak strategic planning system, procedural documentation, and continuous evaluation by top management. The study concluded that PT. X requires comprehensive and systematic improvements, prioritising documentation, safety programme planning, and management review to build the foundation of an effective mining safety management system in accordance with the regulations of the Ministry of Energy and Mineral Resources.

Abstract

This study examines the shadow embroidery (sulaman bayangan) textile craft produced by the Gus Fitri micro, small, and medium enterprise (MSME) in Barung-Barung Balantai, Pesisir Selatan Regency, West Sumatra. The research aims to identify and describe the forms and functions of the shadow embroidery products, and to analyze the techniques, production process, and business development of the enterprise. A descriptive qualitative method was used, with data gathered through observation, in-depth interviews, and documentation involving the owner, two craftswomen, and one customer selected through purposive and snowball sampling, then analyzed using the Miles and Huberman interactive model. The findings show that Gus Fitri produces prayer garments (mukena), traditional blouses (baju kurung), and shawls dominated by floral and Minangkabau motifs, which simultaneously fulfil physical, social, and cultural functions. The reverse-stitch (jahit terbalik) technique creates the signature shadow effect, and the enterprise has innovated by adding a raised-appliqué technique. Production runs through motif design, motif transfer, hand embroidery, and finishing stages, carried out manually by around forty craftswomen. Across three generations the business has diversified its products, expanded its workforce, received institutional coaching, and adopted digital marketing, while still facing constraints in skilled labour and promotion. The study concludes that Gus Fitri exemplifies how a traditional textile craft can be documented, sustained, and creatively developed within a contemporary market.

Abstract

The need for non-potable water in vertical residential buildings, especially simple rental flats (rusunawa), continues to increase along with the number of occupants and variations in domestic water use. Dependence on centralized water distribution systems makes these buildings vulnerable to supply disruptions. Therefore, an Internet of Things (IoT)-based Rainwater Harvesting (RWH) system is proposed as an alternative strategy to support sustainable non-potable water supply. This study analyzes rainfall potential, estimates domestic non-potable water demand, designs storage and distribution components, and integrates IoT-based monitoring for water level, pressure, and selected water-quality indicators. The analysis used rainfall data from the nearest relevant rainfall stations for the study area, frequency analysis with the Log Pearson Type III distribution, design discharge estimation using the Rational Method, field observation, and laboratory rainwater quality testing. The results show that the 10-year return-period rainfall is 282.624 mm/day, producing a design discharge of 0.00351 m³/s for a 1-hour rainfall duration. The daily water demand is 3.35 m³, and the proposed system uses an existing 23 m³ Ground Water Tank (GWT) and a 4.40 m³ Roof Water Tank (RWT), supported by pumps, a first-flush diverter, filtration, and a web-based IoT dashboard. Because nitrate, pH, Total Coliform, and E. coli exceed the applicable quality limits, the harvested rainwater is recommended for non-potable uses such as flushing, sanitation, and environmental cleaning after appropriate treatment.
