Abstract

Penelitian ini dilatarbelakangi oleh banyaknya ditemukan perubahan sosial  dalam novel Orang-orang Blanti karya Wisran Hadi. Tujuan penelitian ini adalah  untuk; (1) mendeskripsikan bentuk perubahan sosial yang terefleksi  dalam novel Orang-orang Blanti karya Wisran Hadi, (2) mendeskripsikan penyebab perubahan  sosial yang terefleksi dalam novel Orang-orang Blanti karya Wisran Hadi. Jenis penelitian ini adalah penelitian kualitatif yang menghasilkan data deskriptif yang berupa kata-kata tertulis. Berdasarkan hasil penelitian dapat diketahui bahwa:  Pertama,  dalam novel Orang-orang Blanti  terdapat empat bentuk perubahan sosial, yaitu perubahan pengelolaan harta pusaka,  pergeseran posisi bundo kanduang,  perubahan peran penghulu, dan perubahan  sistem perkawinan. Kedua, dalam novel Orang-orang Blanti  terdapat dua penyebab terjadinya perubahan sosial. Dua  penyebab yang sangat berpengaruh besar dalam perubahan tersebut yaitu faktor ekonomi dan kekuasaan, serta  kekacauan dalam negeri.

Abstract

This paper presents experimental study of hydraulic characteristic of water filled rubber dam. Several parameter had been studied such as v-notch, vibration phenomena, geometry deformation and discharge coefficient. Good agreement was found between experimental study and literature study.The result had shown that: V-notch phenomena does not occur on water filled rubber dam for any deflated height, vibration phenomena was occured when deflated height reach 43% from the actual height, the discharge coefficient for free-flow is bigger than submerged-flo and the deformation were reached for both free flow and submerged flow condition.

Abstract

Roselle (Hibiscus sabdariffa) contains flavonoids with antioxidant activity. The present study aimed to examine the characteristics and antioxidant activity index (AAI) of roselle extract (RE) after being modified into nanoparticles chitosan of roselle (NCR). Phytochemical screening indicated that roselle extract contains flavonoids, saponins, tannins and steroid/triterpenoids compounds. The NCR was prepared using a bottom-to-up method from a cross-link reaction between chitosan and tripolyphosphate. The ratio of RE:Chitosan:Tripolyphosphate was 2:1:0.1. NCR characterization showed 464.6 nm of a particle size, 0.849 of a polydispersion index and -6.0 mV of a zeta potential. Antioxidant activity was measured by utilizing the DPPH method (2,2-diphenyl-1-picrylhydrazyl), with a UV-Vis spectrophotometer at a wavelength of 515 nm. IC50 data were analyzed using the One Way Annova test with a confidence level of 95%. Results showed that NCR had an IC50 value of 22.577 ppm (AAI:2.217), which is classified as a very strong antioxidant. The IC50 value of the RE was 77.610 ppm (AAI:0.644), which is categorized as a moderate antioxidant. The results of this study reveal that the modification of roselle extract (RE) into nanoparticles chitosan of roselle (NCR) was proven to enhance the AAI (p<0.05).

Abstract

This teacher mentoring program significantly enhanced the understanding and capabilities of teachers in Garut Regency in integrating Project-Based Learning (PBL) and digital technology to develop students' presentation skills. Key indicators of success included high teacher enthusiasm and a shift in their mindset regarding the importance of oral communication in the digital era. Active collaboration among lecturers, students, and partner teachers not only fostered innovative project designs but also ignited a new spirit in creating learning environments that empower students to speak more confidently. Thus, the program has directly contributed to improving the quality of education in Garut, equipping students with essential 21st-century communication competencies. For sustainability, strengthening long-term collaboration, providing continuous digital learning resources, and conducting further impact studies to directly measure the program's effects on students are recommended.

Abstract

In recent years, Public-Private Partnership (PPP) schemes have been increasingly used in Indonesia. PPP schemes attract foreign investment because they are cost-efficient. However, the waste-management sector has not reaped these benefits due to a gap in sectoral regulation. This paper addresses the issues of legal loopholes and proposes fundamental elements that should be included in future waste-management PPP legislation. The results of this paper are intended to assist legislators in developing future regulations for the sector. We employed a qualitative research method, specifically through a normative legal approach by relying on international standards and comparative provisions across jurisdictions. Our analysis identifies three main aspects that future legislation should include. First, waste-management PPPs require an explicit legal and policy framework that governs financing schemes, including clear and investor-friendly principles and options. Second, tax incentives are essential. To enable effective participation, legislation should provide tax and customs incentives (e.g., tax holidays and exemptions). Third, incentives related to local content requirements (TKDN) are highly required. One persistent barrier to market entry in PPP projects is strict TKD requirements and high import costs. Therefore, we propose TKDN mechanisms that incentivize investors to participate in the projects by reducing TKDN thresholds in the sector.
