Exploratory study of factors influencing fraud in the national health service in Buton Islands from a hexagon model perspective

Fraud in National Health Insurance of Indonesia, known as Jaminan Kesehatan Nasional (JKN) services, is a problem that can potentially occur in all hospitals in Indonesia. This research aims to explore the factors that influence the occurrence of fraud from the perspective of the Hexagon model in JKN services in several hospitals in the Buton Islands. The Hexagon model, which consists of six key factors—opportunity, ability, arrogance, pressure, rationalization, and collusion—was used to systematically analyze the occurrence of fraud. This research uses an exploratory study method with in-depth interviews with 30 key informants. The research results show that the factor that most influences the occurrence of fraud is opportunity, followed by ability and arrogance. Although the model suggests pressure and rationalization as contributing factors, these elements remain ambiguous in this study due to insufficient supporting data. Collusion plays an important role in fraud but does not always occur. The study resulted in the development of a preliminary predictor model based on the findings, which can be used to identify risk factors for fraud in JKN services. This predictor model can be used to identify risk factors for fraud so that more effective prevention and response can be carried out.

Identifying the effect of adding coconut coir on the characteristics of the top layer of pure natural buton asphalt concrete wearing course (AC-WC)

Buton Asphalt is natural asphalt originating from Buton Island (Indonesia), with the potential deposit amount reaching up to 662 million tons. This substantial domestic mining potential must be utilized for domestic road needs and to boost the country's economy. However, Buton asphalt's utilization is minimal compared with imported oil asphalt, which reached a usage rate of up to 94 % in 2022. Therefore, as a form of a solution-oriented policy, Buton asphalt is included as one of the 21 commodities in the Strategic Roadmap for Downstream Investment in Indonesia, followed by various supportive regulations for developing this Buton asphalt product. One of the leading products the government targets is natural pure Buton asphalt. This product consists of >99 % bitumen content after extraction, also called Pure Buton Asphalt. The idea was to modify pure Buton asphalt with coconut coir to increase the Marshall Stability and Dynamic Stability values to make the asphalt mixture more resistant to vehicle loads and rutting. The tests were conducted to determine the optimum asphalt content (OAC) of the mixtures, Marshall's Stability comparison, and the dynamic stability test using a Wheel Tracking Machine to identify the comparison of permanent deformation. This study analyzed the Marshall characteristics and dynamic stability characteristics with variations in coconut coir content of 0.5 %, 0.75 %, and 1 % by weight of asphalt and variations in coconut coir length of 0.5 cm, 1 cm, and 1.5 cm. Based on the results of this study, the optimum asphalt content in this study is 6.76 %, where pure Buton Asphalt modified with coconut coir has an increase in Marshall's stability value and dynamic stability value compared to pure Buton asphalt without additional coconut coir

PT PERTAMINA MOR VI’S STRATEGY TO FACE ASPHALT IMPORT PROHIBITION

This research was conducted because of the import prohibition phenomenon by the President of the Republic of Indonesia (RI), Joko Widodo, who stated that asphalt imports would stop in 2024. This phenomenon is fascinating because Indonesia also has a significant demand for asphalt compared to production. This phenomenon also impacts PT Pertamina MOR VI, a state-owned company involved in the asphalt business. This research was conducted to determine the strategy of PT Pertamina Marketing Operation Region (MOR) VI to deal with this phenomenon. Research data was collected through an interview process. The results obtained from the interview show that the first strategy implemented was to increase the limitations of the asphalt refinery at the Pertamina Refinery Unit IV and asphalt production on Buton Island. After overcoming production limitations, PT Pertamina MOR VI focused on setting national product prices based on the Argus Asphalt Index, Opex, and sales margins to compete with global asphalt prices and competitors. The final strategy is how PT Pertamina MOR VI maintains and increases its asphalt marketing market share among agents. These three strategies effectively overcome the effect of asphalt import prohibition in 2024.

Long climate data information will be very useful for the sustainable agricultural sector in determining physiological processes, growth to plant productivity. The Climate Hazard Group Infrared Precipitation with Station (CHIRPS) data is used as a rainfall database for the latest Oldeman agro-climatic zone mapping in Southeast Sulawesi Province. CHIRPS data for 1981-2021 was processed using the Inverse Distance Weighted and Overlay interpolation methods through the Geographic Information System. The results showed that there were thirteen Oldeman agro-climatic zones in Southeast Sulawesi Province, namely B1 (23,71%), B2 (1,97%), B3 (0,22%), C1 (13,48%), C2 (23,21%), C3 (4,64%), D1 (7,36%), D2 (16,71%), D3 (1,28%), D4 (0,00%), E1 (2,92%), E2 (2,32%), dan E3 (2,18%). Zones B1, B2, and B3 are in the northwest, east, and southeast of the area which are very suitable for cultivating two paddy crops followed by planting various types of secondary crops (palawija) during the dry season. Zones C1, C2, and C3 which stretch from west to east are suitable for one-time planting of paddy and two crops of palawija crops. Zones D1, D2, D3, and D4 are spread from the northwest to the southwest to most areas of Muna Island and Buton Island which are suitable for one short-lived paddy planting and one paddy or palawija crop. The agro-climatic zones E (E1, E2, and E3) in the northwest and southwest are only suitable for one crop of palawija crop, depending on rain. The resulting agro-climate map can be used as a reference for cropping patterns that are suitable for the region of Southeast Sulawesi Province.

Pengaruh Kebisingan Terhadap Kelelahan dalam Pekerjaan Pembangunan SUTT 150 kV Raha Bau-Bau Section 1

The construction of transmission line is one of the national strategic projects to even out development, especially with regard to the need for electric power. The construction of transmission line Raha – Baubau will connect two islands in Southeast Sulawesi Province, namely Muna Island and Buton Island. PT PLN (Persero) UPP Sulawesi Tenggara as the project director on this project is very concerned about K3 (Occupational Safety and Health) starting from the planning, work, testing and operation stages. Measurements of the work environment have been routinely carried out every semester but there has never been a study on the impact of noise on worker fatigue in the field. The sources of noise during this construction work include breakers, concrete mixers, ironworks, erection towers and stringing machines. With a total workforce of ±80 people and work intensity/noise exposure of 8 hours/day and the impact of noise risks that are not yet known, it is necessary to conduct research to identify and mitigate the risks of fatigue due to noise in the construction work of transmission line Raha-Baubau Section 1.

Characteristics of Asbuton Mix Using Geopolymer Fly Ash Coarse Aggregate as a Substitute for Natural Aggregates

The increase in the number of road construction projects has led to an increase in the need for road pavement materials (aggregate and asphalt). Currently it takes about 1.6 million tonnes/year of asphalt, as well as aggregate. Seeing these conditions, it is necessary to anticipate the use of waste or natural resources that have not been utilized optimally. In this study, fly ash (PLTU waste) was used as aggregate and Asbuton (Buton Island rock asphalt) was used as a binder for the asphalt mixture. As an effort to save energy, the stirring system is cold. Based on the volumetric characteristics of the artificial coarse aggregate, it only meets the specifications for the VMA value, while the VIM and VFB values have not been met. The mechanical properties (stability and flow values) of the cold asphalt mixture on the replacement of natural aggregate with 25% artificial aggregate met the requirements, but did not meet the Marshall Quotien requirements

PENINGKATAN POTENSI WISATA LA BOLONTIO TERHADAP PENGEMBANGAN KEMAJUAN PENDAPATAN PEMERINTAH DESA DI SIOMPU KABUPATEN BUTON SELATAN

One of the potentials that can be increased to Village Original Income (PADes) for villages in Indonesia is the tourism sector. Touring in the village has become a separate choice for tourists. Tourists who like tourist attractions in the village are not only interested in its natural beauty but also interact with local people. Tourist attractions provided by various villages in Siompu are one of the goals of the village government in increasing village income as a form of village development and progress. The government manages various places that are considered to be developed as a source of extraordinary income and progress in managing villages and can compete in the world of tourism which shows the natural beauty that exists in their villages as seen in Siompu, one of the islands or Kaimbula Village which has natural beauty and the ocean. The village government takes advantage of the beauty of the coast of the island in the village of Kaimbulawa as a form of developing tourism potential in advancing the village and being able to compete with other islands. kaimula village is located on a plateau and the lowland is the ocean so the location of where they live requires them to live in the highlands. However, the beauty of the coast which is quite stunning is utilized by the village government as a form of economic income by making Labolontio a tourist spot. The recreation area is also a historical place called Labolontio which is very famous in Buton Island. What makes this tourist spot interesting to visit is not only the beauty of the beach and nature, but also historical places that can be visited and a variety of cultures that attract visitors or tourists.

The Indonesian Government has established pipelines and cable corridors through the Decree of the Minister of Marine Affairs and Fisheries Number 14 of 2021 concerning Submarine Pipelines and Cables. Indonesia’s strategic position in the world has become a favorite route for laying submarine cables, connecting Australia and Indonesia with America and other countries. The purpose of this study is to conduct a technical study of the existing ratified route corridor on the geological conditions of the Indonesian waters. The method used is path analysis of geological and geomorphology conditions by compiling class criteria related to and increasing risks to geological conditions. The results of the geological analysis show that several submarine cable lines pass through volcanic areas and faults; also, there are areas with a seabed side slope of >20%. This condition can affect the cable laying process, operations, and vulnerability. In addition, it is necessary to rearrange the paths that have a high hazard vulnerability to disasters and other activities. The results of this study are in the form of recommendations for proposed corridor revisions that reduce constraints related to geology and geomorphology.

Pengaruh Proses N-Hexane Solvent Extraction pada Ekstraksi Bitumen dari Aspal Buton sebagai Bahan Baku Minyak Bumi Nonkonvensional

Buton tar sand or commonly known as asbuton is a natural tar sand deposit found in Buton Island, Southeast Sulawesi. The reserve of asbuton is approximately 179.1 million tons with a hypothetical resource of oil amounting to 10,577,646,000 liters. Asbuton is potentially used as an alternative raw material for non-conventional oil. Non-conventional oil from asbuton could be used as a substitute to the depleted resources of conventional oil in Indonesia. Asbuton non-conventional oil could be prepared by extracted bitumen, a heavy hydrocarbon material in asbuton tar sand from its mineral. The bitumen then could be further processed to produce non-conventional oil. Various studies have been carried out to extract bitumen with various solvents. This study uses direct extraction and soxhlet extraction methods with n-hexane solvent to obtain the most optimum percentage of bitumen. Direct extraction method is done by varying the temperature (40, 45, 50, 55, 60oC) and the weight ratio of asphalt and n-hexane solvent (1:20; 1: 30; 1:40; 1:50). Based on the results of research that has been done, the highest percentage of bitumen yield is formed at 40oC and at a ratio of 1:20 that is 88.60% for the direct extraction method. The 1:40 ratio of soxhlet solvent extraction has the highest bitumen yield of 90.97%. After that, a characteristic analysis was carried out using FTIR with a strong absorbance in the area of 1423.47; 1033.85; 873.75; 709.80 cm-1 representing the C-H and C = H groups.

Diversity of arbuscular mycorrhizal fungi in asphalt post-mining land in Buton Island, Indonesia. Biodiversitas 23: 6327-6334. Studies on the presence and diversity of Arbuscular Mycorrhizal Fungi (AMF) on overburden (OB) and asphalt post-mining areas in Buton Island are still limited. The purpose of this study was to examine the presence and diversity of AMF on OB and asphalt post-mining stockpiles in Buton Island, Southeast Sulawesi Province. The sampling of soil and roots of successional plants was carried out at eight post-mining sites at the IUP Kabungka (Pasarwajo) (6 sites) PT. WIKA Aspal and IUP Lawele (2 sites), PT. WIKA Bitumen. The AMF spores were isolated using the wet filter pour method, followed by the identification of AMF which was done by observing the morphology of AMF spores. The results showed that all successional plants were in symbiosis with AMF, which was indicated by the existence of AMF structure in plant roots with the percentage of AMF colonization ranging from 5 - 95%. The number of spores per 50 g ranged from 1 to 9 spores. A total of 9 AMF species were found to belong to five genera, i.e., Claroideoglomus, Haloatospora, Glomus, Gigaspora, and Cetraspora from three families. Claroideoglomus claroideum was found to be the most dominant species isolated with the high occurrence and the highest Importance and Shannon-Wiener Diversity Indices followed by Haloatospora cf. pansihalos, Glomus sp. 5, and Glomus sp. 4. This study also showed that the AMF diversity index differed among locations. The presence of AMF can accelerate the emergence and development of adaptive plants on post-asphalt mining land in Buton Island.
