The purpose of this study was conducted to determine the effect of capital expenditures and balancing funds on regional financial. To find out Regional Original Income (PAD) as a moderating variable that moderates the relationship between Capital Expenditures and Balancing Funds on Regional Financial Performance in Regency and City Governments in the Riau Archipelago Province. The population is 7 districts/cities in the Riau Archipelago which were sampled with the 2011-2017 observation period. This study uses partial regression analysis (Partial Least Square / PLS) to test the five hypotheses proposed in this study. Each hypothesis will be analyzed using Smart PLS 2.0 software to examine the relationship between variables. The results showed that Capital Expenditures had no significant effect on Regional Financial Performance, as indicated by the t-statistic value of 0.029 which is smaller than the t-table value of 1.674. Balancing Funds obtained a p-value of 0.001 with a t-statistic value of 3.203 > 1.674, which means that Balancing Funds have a significant positive effect on Regional Financial Performance with a significance level above 5% (significant). The test results for Regional Original Income (PAD) moderate the relationship between Capital Expenditures obtaining a p-value of 0.347 with a t-statistic value of -0.941 <1.674 t-table which means that the Regional Original Income (PAD) variable moderates the relationship between Capital Expenditure of 0.85% which has no significant effect with significance on Regional Financial Performance above 5% (significant). Local Own Revenue (PAD) moderates the relationship between Balancing Funds on Regional Financial Performance with a p-value of 0.727 with a t-statistic value of 0.349 <1.674 which means that Regional Original Income (PAD) moderates the relationship between Balancing Funds that has no significant effect on Regional Financial Performance with a significance level below 5% (significant). The F table value is at 5% significance with df1 = 3 and df2 = (49-3) of 2.84. The Fhiung value of the regional financial performance variable (12.31) is greater than (<) the Ftable value (2.84), with this result there is a mutual influence between the variables Capital Expenditures, Balancing Funds on Regional Financial Performance.

The Humanitarian Tragedy of "Wadas and Rempang Island" Forms of Neo-Colonialism and New-Style Neo-Capitalism and the Collapse of Law in Indonesia

<em><span lang="EN-US">The clash on September 7, 2023, between Rempang residents and security forces (POLRI, TNI), which ended with the arrest of 43 residents, mirrors the conflict that occurred between the residents of Wadas Village, Bener Subdistrict, Purworejo Regency, Central Java, and the Central Java Regional Government on February 8, 2022. The violence perpetrated by security forces against the residents of Rempang Island occurred when the company, escorted by security, unilaterally staked out Malay customary land in 16 traditional villages on Rempang and Galang Islands in the Riau Archipelago, covering an area of 17,600 hectares. This included 10,028 hectares of protected forest, or about 45.84% of the total land area, which they had occupied since 1834. According to the head of Batam Concessionaires (BP), Muhammad Rudi, the Eco City development plan has been underway since 2004. At that time, PT. Makmur Elok Graha and Xinyi Glass Holding Ltd. (July 2023), the exclusive rights holders, became the private entities partnered with the government (September 12, 2023), receiving an 80-year concession from the government. The government's actions of land seizure and violence demonstrate a form of power arrogance that tends toward abuse of power, under the pretext of protecting a 381 trillion investment, while ignoring the rights of citizens as stipulated in the 1945 Constitution and the Basic Agrarian Law. The government's actions represent forms of Neo-Colonialism and Neo-Capitalism occurring during the Jokowi administration. This situation underscores that the law is no longer equal; the law has collapsed, becoming merely a symbol that only favors power.</span></em>

Strategi Pengembangan Pariwisata Berkelanjutan Gurun Pasir Telaga Biru Pulau Bintan Era New Normal

The research was conducted in the Telaga Biru Desert, Bintan Regency, Riau Archipelago. The purpose of this research is to explore the tourism potential of the Telaga Biru Desert ecotourism destination and collaborative management that can be applied as an effort to develop a sustainable tourism area. Gurun Pasir Telaga Biru is part of an industrial area owned by PT Surya Bangun Pertiwi (SBP) with a land reserve of 4,000 hectares. Telaga Biru Desert has an area of 50 hectares which is planned as an industrial area green belt because of its location close to the Bintan airport. This research uses mixed methods, namely analysis from observations and interviews supported by quantitative data using Maple 2017 to understand the economic value and willingness of tourists to pay when visiting the tourist destination of the Telaga Biru Desert Desert. PT Surya Bangun Pertiwi (SBP) can use the Total Economic Value results as a data review to decide whether to keep the area as idle land or develop it as a nature-based tourism destination. The total economic value of the Telaga Biru Desert is IDR 493,950,214,550 per year, which means the economic value is IDR 862,290 per meter2. This figure is relatively high when compared to small businesses in providing a place with adequate facilities. Tourists can explore tourist areas with various interesting spots and try various kinds of rides provided. This destination will be more valuable if it carries out good collaborative management with more adequate infrastructure and can encourage the growth of MSMEs, education and the social community of the local community.

SPATIAL-TEMPORAL DISTRIBUTION OF NARROW-BARRED SPANISH MACKEREL (Scomberomorus commerson) FISHING GROUNDS IN RIAU ARCHIPELAGO WATERS, INDONESIA

Narrow-barred Spanish mackerel (Scomberomorus commerson) is an exportable fish captured by gillnet fishing fleets from Bintan Regency. The fleets are operated in the Riau Archipelago waters but information on their activities is limited. Such information is important to the institution the Agency for Marine and Fisheries Affairs of Archipelagic Riau Province for ensuring the sustainability of the fisheries from both economic and biological perspectives. This study aims to determine the spatial-temporal distributions of the mackerel fishing grounds along the year with reference to the capture data, sea surface temperatures, chlorophyll-a concentrations, and salinities in the last 4 months of 2022. This study analyzed data from a fish export company, the PSDKP office at Tanjungpinang, Bintan, interviews of fishers affiliated with 44 fishing boat samples, and satellite-based marine data. Analysis on the monthly fishing productivity and optimum marine conditions for the mackerels were carried out to determine prospects of five recognized fishing grounds. Besides Lingga Islands, the fishing grounds are highly prospective from August to November. The longest fishing seasons are expected around Bangka Island (11 months). The spatial and temporal patterns show that the north-south-north shifts in fishing grounds that are associated with regional climates, i.e., monsoon winds.

The Role of Employee Empowerment in Mediating the Effect of Leader-Member Exchange on Employee Performance in Dekranasda Riau Islands Province 2021-2024

The decline in the performance of employees at Dekranasda in the eight districts/cities of the Riau Archipelago province is the background of this research. This study aims to uncover and analyze the effect of empowerment, which mediated the effect of Leader Member Exchange (LMX) on employee performance in Dekranasda, which is dispersed toward eight regencies/the city of Riau Islands Province. The study contributes to the development of the LMX concept, which fosters its relation toward employee performance mediated by engagement. Furthermore, the study uses survey methods for gaining the data by questionnaire. The total respondents involved in this study are 303 persons in the Dekranasda Office Riau. The analysis data used Structural Equation Modeling (SEM). This study shows that LMX directly and significantly affects employee performance. Furthermore, empowerment affects employee performance positively but does not mediate the effect of LMX on employee performance. This study merely involves the employees of Dekranasda, who are dispersed in the eight districts/cities of the Riau Archipelago province. This study shows the importance of direct interpersonal relationships between managers and employees in the realm of public service. As suggested by the LMX theory, managers delegate responsibility and provide more support and appreciation to subordinates in the group, which is considered as empowerment. The results of this study are consistent with the LMX theory, which emphasizes the importance of interpersonal factors in the workplace, especially in the local government sphere. The results of this study can be used as a basis or input for stakeholders in Dekranasda in designing an ideal relationship between superiors and subordinates so that subordinates are able to produce good performance to achieve organizational goals.

Strategi Mengatasi Aksesibilitas Destinasi Pulau Kecil Dengan Penyesuaian Segmentasi Wisatawan Kepulauan Riau

A prevalent challenge encountered by small islands pertains to accessibility. Nevertheless, numerous ostensibly isolated islands attract a substantial number of tourists. This article examines the relationship between accessibility and tourism development on small islands to understand the two better. Qualitative data collection methods were utilized for this study, including in-depth interviews, the collection of pertinent secondary data, and field observations. Following analysis, the collected data were presented in a comparative descriptive fashion. A discussion of the island approach (islands and archipelagos) is undertaken to comprehend the interconnections between minor islands and other locations within the larger region. Field research indicates that despite possessing the aesthetic appeal of beaches and sea, many small islands still need to exploit their tourism potential fully. This is primarily due to the exorbitant transportation expenses for domestic visitors and the need for adequate tourism infrastructure, including resorts and hotels of international caliber catering to affluent-class tourists (middle and above). Conversely, despite being classified as remote islands, the Riau Archipelago maintains strong diplomatic relations with neighboring nations. It can attract international visitors for cultural tourism, beach activities, and scuba diving. Small islands may benefit from a strategy targeting affluent classes and foreign tourists. In order to develop the tourist experience on small islands by expectations, it is necessary to enhance tourism infrastructure and services for tourists and tourism investors as a result of targeting the tourist segment.

Epizoic yellow sponge (Poecilosclerida, Demospongiae) expansion on living Scleractinian corals in Bintan, Riau Archipelago, Indonesia

AbstractCoral reef ecosystems in Indonesia are under threat due to changes in the environment driven by global climate change, along with local disturbances such as sedimentation and eutrophication. Consequently, comprehensive coral reef monitoring activities have been initiated at numerous locations across Indonesia. In this study, the findings from coral reef health surveys across 14 reef sites (within 40 hectares) in the Bintan area (Riau Archipelago, Indonesia; 100 km southeast of Singapore) revealed a potentially novel epizoic yellow sponge species (Phorbas sp.) that overgrows coral colonies. This species, tentatively classified as a new Phorbas sp. (order Poecilosclerida: family Hymedesmiidae), was identified through a combined approach employing classical taxonomic methods along with DNA barcoding using the cytochrome c oxidase I (COI) gene. At every site, three permanent 20‐m transects were established to annually monitor live coral coverage and species composition between 2014 and 2017. The survey indicated a notable change in the overall coral cover during this period. The abundance of coral diseases was investigated in 2014 and 2017. Additionally, the progress of Phorbas sp., was closely monitored (i.e., every second day for one week) at Bintan Island (site 11) during the dry season in August 2017. This approach aimed to approximate the relative impact of each incident on the coral's condition. The results indicated that the most comprehensive change occurred due to the overgrowth of Phorbas sp., which affected 12 scleractinian coral species across eight genera in almost all sites except one. The abundance of this epizoic sponge infestation was highest at Pulau Beralas Pasir (site 10), constituting 22.9% of all recorded life forms, and lowest at Pulau Pangkil‐Besar (site 13), with only 0.7%. The expansion of the thin yellow sponge tissue was estimated to increase by up to 0.51 ± 0.48 cm2 per day on Porites coral.

Optimizing Public Service through Innovative Talent Management Strategies for Public Officials: A Case Study in the Riau Islands Province

Talent Management is a crucial element for public organizations, which includes absorbing, identifying, and retaining civil servants who have outstanding talents in each organization and make a significant contribution to the progress of public organizations to create excellent public services. A talent management model in the public sector, especially at the local government level, is needed because approximately 80% of civil servants are placed in the regions, and the dynamics of the bureaucratic environment are more dynamic and complex. The Riau Archipelago Province is one of the areas that has implemented a merit system, but the career pattern could have gone better. This study aims to analyze strategies for implementing Talent Management to accelerate bureaucratic reform and manage the capacity of civil servants in the Provincial Government of the Riau Archipelago. This research method uses a qualitative exploratory case study methodology. The results of this study show that the Riau Islands Provincial Government has not implemented Talent Management for civil servants by the mandate of the PAN RB Ministerial Regulation Number 3 of 2020, which is currently in the preparation stage of regulations in the form of a Governor's Regulation concerning the Management of Civil Servants Talents in the Islands Provincial Government Riau. Therefore, aspects of career development in the merit system must be a significant concern so that the Riau Islands Provincial Government can meet the desired targets.

Pengaruh Pemberian Susu Kedelai (Glycine Max) Terhadap Peningkatan Produksi ASI Pada Ibu Post Partum

Unsmooth milk production is the main problem causing the failure of the breastfeeding process. One way to increase milk production for post partum mothers is to support the nutritional needs of mothers, one of which is by consuming soy milk made from soy beans. This study aims to determine the effec tof soymilk (Glycine Max) on breast milk production in post partum mothers at Bakti Timah Hospital Karimun Riau Archipelgo. This researchis a pre-experimental study with a one-group pretest-posttest design. The population in this study were post partum mothers at Bakti Timah Hospital Karimun Riau Archipelago in the last one month as many as 102 people. The sampling technique in this study used a sampling technique carried out using purposive sampling of 34 respondents. The research instrument used a breastmilk production questionnaire, namely the Lactation Assessment Tool (LATCH) which consisted of 5 points. Data analysis was performed univariately and bivariately using the Wilcoxon test. The results showed that before consuming soy milk the average milk production was 3.35 and after being given soy milk the average milk production increased to 4.03. The results of the Wilcoxon test found a p-value of 0.001 (p <0.05) so it can be concluded that there is an effect of soy milk (Glycine Max) on increasing milk production in post partum mothers. It is recommended for the community, especially post partum mothers, to be able to use soy milk as an alternative to addressing problems with increasing breast milk production.

Assessment of Soil Degradation for Biomass Production in Tanjungpinang, Indonesia

Land management, especially land that is not in accordance with the rules can cause damage/change in soil properties which in turn impacts the disruption of biomass production. The lack of available data regarding soil degradation, especially in Tanjungpinang City, has resulted in less than optimal supervision and control over land management. Mapping the condition of soil degradation is necessary to exercise control over land management. The purpose of this research is to assess soil degradation in Tanjungpinang City, Riau Archipelago for biomass production. Soil degradation can be modeled by scoring and overlaying four parameters, namely land use, slope, soil type, and rainfall, producing a tentative map of potential soil degradation. Next, a tentative map of soil degradation is corrected using a field survey. Field surveys are used to measure the standard criteria for soil degradation according to Government Regulation No. 150 of 2000. The results show that the criteria for soil degradation in Tanjungpinang City are light damage and moderate damage. The criteria for moderate damage have the largest area spread over Dompak Sub-District, Batu Sembilan, Melayu City Plate, Bukit Cermin, West Tanjungpinang, East Tanjungpinang, Kampung Baru, and Tanjung Ayun Sakti. The main limiting factors that limit land use in Tanjungpinang City are permeability, surface rocks, and redox.

Metabolomic study on the effect of Indonesian propolis in hypertensive rats

Context: Hypertension is a health problem that is a major factor triggering cardiovascular diseases; however, effective treatment has not been found. Aims: To evaluate the effectiveness of Indonesian propolis in hypertension treatment through metabolomic study. Methods: A total of 36 Sprague Dawley rats were divided into 6 groups, including standard diet group, high-NaCl diet group, high-NaCl diet + captopril group (25 mg/kg), high-NaCl diet + propolis from Riau Archipelago group, high-NaCl diet + propolis from Lampung group, high-NaCl diet + propolis from South Sulawesi group. An 8% NaCl diet was used to induce hypertension for 3 weeks, while 200 mg/ kg propolis was administered for 1 week following the induction. The bioactive compounds of ethanol extract of propolis were identified using UHPLC. Moreover, the metabolomic profile was performed using LC-MS/MS. Data was processed using principal component analysis and was used for metabolic pathway analysis. Results: All propolis samples significantly ameliorated the blood pressure of hypertensive rats. The metabolites that were mainly found in rat serum were amino acids, glycerophospholipids, and acylcarnitine. Rats administered with propolis from South Sulawesi had the closest metabolite profile to the standard group, where L-acetylcarnitine could be the potential marker of hypertension. Several metabolic pathways, including the degradation of tryptophan, β-fatty acid oxidation, degradation of threonine, and 2-oxobutanoic acid, were the most impaired pathways in hypertension. Conclusions: Indonesian propolis, especially from South Sulawesi, could be used for controlling blood pressure.

Digital-Based Maritime Tourism Development Policy in the Anambas Islands in Maintaining Maritime Sovereignty

The Anambas Archipelago, one of the potential areas for marine tourism in Indonesia, is located in the Riau Archipelago. Supported by a strategic location, being on the path of New Regional development, becoming an international shipping lane and directly adjacent to the State of Singapore. This study aims to look at the policy of developing digital-based marine tourism in the Anambas Islands. This study uses a qualitative method. Source of data obtained from primary data, secondary data. Observation data collection techniques, interviews, documentation, FGD. Triangulation data analysis technique assisted by N-Vivo12Pluss Tools. Maritimetourism development policy is seen from three aspects, namely the policy of compiling E-Tourism prototypes, developing tourist attractions, developing promotion/marketing of marine tourism. The results of the Anambas Islands Regency government have not been optimal in developing digital-based marine tourism. Even though the government already has a National Tourism Development Master Plan (RIPPARNAS) for 2010-2025, which is directed at the development of maritime tourism, there are no specific steps or tourism development policies that carry a digital approach. Based on the theory used, it is known that tourists' needs for accessibility where information access facilities must be easily achieved and technology supporting facilities such as telecommunications and internet access which are added so as to satisfy tourists using technology and smartphones when traveling in Anambas have not been fully realized. So that the role of digital in the marine tourism of the Anambas Islands has not fully provided a positive influence while digitalization should add excellence to the tourist experience.

Analisis Kapasitas Sistem Saluran Drainase (Studi Kasus Drainase Jalan Siliwangi Kota Batam)

Batam City is one of the cities in the Riau Archipelago Province with the largest population growth. Along with the development of the city and the increase in population, the need for public facilities and infrastructures also need to be developed, such as on Jalan Siliwangi. Jalan Siliwangi is one of the roads in the Batu Besar area, Nongsa sub-district in Batam city which is experiencing problems with the drainage system. Drainage is a technical measure to prevent excess water due to high rainfall intensity and drain it to a collection point. Rainfall intensity is a condition where rain is highly concentrated and occurs at a certain time. This research was conducted to know whether the Siliwangi Road drainage channel is working optimally so that it can accommodate water during high rainfall. This analysis uses the Gumbel method using extreme values. The extreme values of rain intensity that will be taken into account are several return periods, namely 2, 5, 10, 25, 50, and 100 years. The calculated channel discharge using location data is Q = 0.5637 m3/second, while the planned discharge calculated using rainfall data is Q = 2.064 m3/second. From the results of the analysis of the dimensions of the planned canal found in the field, it does not meet the design capacity so waterlogging occurs, where the height and width of the planning canal are larger. By using the frequency distribution formula of the Gumbel and Log Person Type III methods for the calculation and application of parameters related to the analysis of average data, standard deviation, and determining the frequency of rainfall for the T-year return period in the discussion above, it can be concluded that the drainage channel on Jalan Siliwangi Batam unable to prevent inundation or flooding during high rainfall.
