Abstract

This study examines the concept and application of insurance within the framework of business law, with particular emphasis on legal regulation, fundamental insurance principles, and dispute resolution in insurance claims. The research employs a normative juridical method through statutory and literature approaches, analyzing relevant laws, regulations, and legal doctrines related to insurance practices. The findings indicate that insurance plays a crucial role in providing legal protection and financial security by transferring risk from the insured to the insurer. However, in practice, disputes frequently arise due to differences in the interpretation of policy provisions and the application of the principle of indemnity. These issues highlight the importance of legal clarity, transparency, and good faith in insurance agreements. Therefore, a comprehensive understanding of insurance principles and contractual obligations is essential to ensure legal certainty and fairness for both insurers and policyholders.

Abstract

Tujuan – Penelitian ini bertujuan untuk menganalisis pengaruh pelatihan kerja, etos kerja, dan keselamatan serta kesehatan kerja (K3) terhadap kinerja karyawan pada PT. Steelindo Wahana Perkasa Kabupaten Pelalawan. Desain/metodologi/pendekatan – Penelitian menggunakan pendekatan kuantitatif dengan metode survei. Populasi penelitian berjumlah 104 karyawan, dengan sampel sebanyak 95 responden yang ditentukan melalui teknik purposive sampling. Data dikumpulkan menggunakan kuesioner dan dianalisis dengan regresi linier berganda menggunakan bantuan perangkat lunak SPSS. Temuan – Hasil penelitian menunjukkan bahwa pelatihan kerja, etos kerja, dan K3 secara simultan berpengaruh positif dan signifikan terhadap kinerja karyawan dengan nilai koefisien determinasi (R²) sebesar 0,865. Secara parsial, pelatihan kerja, etos kerja, dan K3 masing-masing berpengaruh positif dan signifikan terhadap kinerja karyawan. Variabel pelatihan kerja menunjukkan pengaruh paling dominan dibandingkan variabel lainnya. Keterbatasan penelitian – Keterbatasan penelitian ini terletak pada penggunaan data persepsional karyawan, pendekatan kuantitatif, serta objek penelitian yang terbatas pada satu perusahaan sehingga hasil penelitian belum dapat digeneralisasi secara luas. Implikasi – Implikasi praktis dari penelitian ini menunjukkan bahwa perusahaan perlu memprioritaskan pengembangan program pelatihan kerja yang terstruktur, penguatan etos kerja, serta penerapan sistem K3 secara konsisten guna meningkatkan kinerja karyawan. Secara teoretis, penelitian ini memperkuat temuan empiris terkait peran manajemen sumber daya manusia dalam meningkatkan kinerja karyawan. Kebaruan – Kebaruan penelitian ini terletak pada pengujian simultan pelatihan kerja, etos kerja, dan K3 dalam konteks industri manufaktur di Kabupaten Pelalawan, yang masih relatif jarang diteliti.

Abstract

The development of information technology continues to increase, driving people's need for fast and affordable internet access. However, rural communities often face obstacles such as weak GSM signals and expensive data plan fees. To overcome these challenges, fiber optic-based RT/RW Net networks are a promising solution, offering stability and high speed at a lower cost than wireless networks. Faqih Teknologi, a micro-enterprise, delivered the Internet Masuk Desa program in Karang Suraga. Despite initially using wireless technology, the company faced obstacles such as vulnerability to lightning, signal interference due to weather and geographical factors, and high maintenance costs. Switching to fiber optic overcame these issues, offering a more stable signal, lower susceptibility to weather, and more efficient maintenance costs. This research uses the Network Development Life Cycle (NDLC) method to design a fiber optic-based internet network system. The NDLC stages include requirements analysis, network design, simulation, implementation, monitoring, and management. This approach ensures that the designed system is able to meet the needs of the community with optimal performance, while opening up new economic opportunities for the community through a partnership-based business model.

Abstract

The development of silica nanofluids for enhanced oil recovery (EOR) has gained significant attention. However,  their application is limited bypoor stability under high temperature, and high salinity conditions. Our previous studies demonstrated that using the anionic surfactant alpha olefin sulfonate (AOS) combined with the co surfactant disodium laurent sulfosuccinate (DLS) at consentrations of 0.3% AOS and 0.3% DLS significantly enhanced thermal stabilility, reduced IFT, decreased wettability, and increased incremental oil recovery. This study reports a one step synthesis method for preparing silica nanofluids using hydrophilic colloidal nano silica (CNS) stabilized with the AOS and DLS at surfactant concentrations above 0.3%. Nanofluids were formulated with formation water from a reservoir in Sumatra, Indonesia. We systematically evaluated the effects of AOS-DLS concentrations on the thermal stability, turbidity, interfacial tension (IFT), wettability, filtration test, and core flooding performance. The optimized formulation of stable silica nanofluids for EOR applications under reservoir relevant conditions was also systematically evaluated. The silica nanofluid (0.3% AOS + 0.3% DLS) exhibited more than 3 months of stability at 60 °C. It also had a low contact angle of 13.88 ͦ and a reduced IFT of 6.3x10-1 mN/m. The filtration ratio was 1.2. Spontaneous imbibition resulted in a recovery factor (RF) of 59%. Core flooding analysis yielded an incremental RF of 12.9% of the OOIP. These results demonstrate the synergistic role of silica nanoparticles and surfactants in improving nanofluid stability, reducing IFT, and enhancing oil recovery. This supports their potential application in chemical flooding for sandstone reservoirs.

Abstract

Institutional and government structures at all levels of government, village government must be directed to be able to create a government that is sensitive to developments and changes that occur in society. Therefore, a synergy relationship is needed between the village government, BPD, the community, and others to support village development. The focus of research is how the role of village government and BPD in village development according to Law no. 6 of 2014 concerning the Village in Sepuk Tanjung Village, Sebawi District, and what factors support the village government and the BPD in carrying out government relations in order to increase village development in the village. The results of the study concluded that the relationship between the village government and the BPD in the scope of development of Sepuk Tanjung Village has a very central role, but there are factors that become the village government and the BPD in implementing village development.

Abstract

Silica nanofluids attract significant attention for enhanced oil recovery (EOR) applications due to their ability to alter rock wettability. However, silica nanofluids exhibit limitations in thermal stability. The addition of anionic surfactants aims to overcome these limitations. The synergisticAnionic surfactants are added to address the thermal stability issues of silica nanofluids. The synergy interaction between silica nanoparticles (SNPs) and anionic surfactants enhances  wettability alteration, reduces interfacial tension (IFT), improves thermal stability, and increasing oil recovery. This study investigates the synergistic effects of SNPs, alpha olefin sulfonate (AOS) surfactant, and disodium laureth sulfosuccinate (DLS) co-surfactant in nanofluid formulations applied to sandstone reservoirs. Laboratory experiments employ colloidal nano silica with two particle sizes, 8 nm (SNP-01) and 3 nm (SNP-02), combined with AOS-DLS anionic surfactants at various concentrations . The study showed that the silica nanofluid remains stable for up to 3 months at temperatures below 80°C for both SNP types at a concentration of 0.1% with surfactant concentrations 0.3% AOS and 0.3% DLS in  3% brine solution. The addition of SNPs decreases the contact angle, whereas surfactants do not significantly affect the contact angle; however, surfactant effectively reduce the IFT, while  nano silica shows minimal influence on IFT values. Core flooding analysis showed that the SNP-02 nanofluid produced the highest recovery factor of 12.1% OOIP. Futhermore, SEM analysis showed that silica nanofluid injection removes surfactant impurities and enhances rock porosity.
