Abstract

Investment or investment activities are defined as activities carried out by individuals and legal entities seeking to increase and maintain the value of their capital, both in the form of cash, immovable assets, intellectual property rights, and expertise. There is a legal basis in Capital Investment and several main provisions that become a reference for carrying out its activities, such as institutional aspects, employment, legal protection aspects and others. This is where it seems very important to understand the main provisions in the field of investment, so that it is clearer in carrying out the related rules, in order to carry out investment properly. The research method in this study uses literature studies that are processed and analyzed through a qualitative approach. This research is qualitative research. Regulations for the implementation of investment licensing affairs in Indonesia are regulated in Law Number 25 of 2007 concerning Capital Investment and several implementing regulations. The duties and functions of investment organizing government institutions in the main provisions in the field of investment have the characteristics of investment licensing carried out through one-stop integrated services, namely the implementation of a permit and non-licensing that receives delegation from institutions or agencies that have licensing and non-licensing authority whose management process starts from the application stage to the stage of issuance of documents carried out in one place.

Abstract

Sargassum sp merupakan jenis rumput laut yang tumbuh subur secara alami di perairan Indonesia, termasuk di Perairan Simeulue, Provinsi Aceh. Sargassum sp. mengandung berbagai senyawa bioaktif yaitu fenol yang berpotensi sebagai antioksidan. Sargassum sp. di Perairan Simeulue belum dimanfaatkan oleh masyarakat setempat dan belum ada laporan ilmiah tentang total fenol dan aktivitas antioksidan dari rumput laut tersebut. Tujuan penelitian ini menentukan aktivitas antioksidan dan total fenol Sargassum sp yang terdapat di Perairan Simeulue. Metode penelitian meliputi pengambilan sampel rumput laut, preparasi dan ekstraksi sampel rumput laut, uji fitokimia, analisis total fenol dan analisis aktivitas antioksidan rumput laut. Analisis data menggunakan analisis regresi linear untuk melihat hubungan total fenol dengan aktivitas antioksidan DPPH Sargassum. Hasil penelitian menunjukkan bahwa total fenol dan aktivitas antioksidan lima jenis rumput laut genus Sargassum (S. muticum, S. binderi, S. crassifolium, S. granuliferum, S. fluitans) di Perairan Simeulue menunjukkan nilai yang bervariasi. Total fenol 7,45-9,02 mg GAE/g dengan nilai tertinggi terdapat pada S. binderi dan nilai terendah pada S. fluitans. Aktivitas antioksidan 74,7-152,4 μg/mL dengan nilai tertinggi terdapat pada S. binderi, sedangkan nilai terendah terdapat pada S. fluitans. Hasil analisis korelasi (R2 = 0,9059) menunjukkan bahwa aktivitas antioksidan rumput laut genus Sargassum berhubungan erat dengan total fenol. Kelima spesies rumput laut Sargassum di Perairan Simeulue mempunyai aktivitas antioksidan yang kuat (74,7-152,4 μg/mL) sehingga berpotensi dikembangkan sebagai antioksidan.

Abstract

Zooplankton or animal plankton, is an organism that is generally small in size whose life is swayed by currents in the free ocean. Banda Sakti District, Lhokseumawe City is a coastal area with potential for the study of its coastal waters, which have not been extensively explored. The purpose of this study was to assess the zooplankton community structure—including abundance, diversity, uniformity, and dominance in the coastal waters of Banda Sakti District, and to evaluate water quality conditions in relation to their suitability for supporting zooplankton life. The research was conducted in December 2021 in the coastal waters of Banda Sakti District, Lhokseumawe City, using a purposive sampling method. A total of 50 zooplankton species representing 10 phyla were identified. The total abundance of zooplankton in this study ranged from 105.55 – 140.27 ind/L. In this study, the diversity index value ranged from 22.14 to 2.77, the uniformity index ranged from 0.65 to 0.79, and the dominance index ranged from 0.04 to 0.05. Overall, water quality parameters indicated that the coastal waters of Banda Sakti District remain within suitable conditions to sustain zooplankton communities according to established environmental standards.

Abstract

The mentoring activity for the Regional Innovation Index Information System (SIIDA) operators in South Lampung Regency was carried out to strengthen digital-based innovation reporting governance. This activity was motivated by the gap between the number of implemented innovations and those officially reported. The main objective was to enhance the competence of regional government operators in understanding innovation classifications and independently inputting data into the SIIDA platform. The implementation method included socialization, hands-on technical training, data verification, and online monitoring. The results indicated a significant improvement, with reported innovations increasing from 64 to 216 and the reporting index score rising from 0.00 to 91.66, while operators’ comprehension improved from 62% to 88%. The activity proved effective in enhancing the technical capacity of local government staff and strengthening evidence-based innovation reporting. In conclusion, this mentoring model is feasible for sustainable implementation as a strategy to improve regional innovation performance

Abstract

Limited access and flexibility in higher education, particularly in the field of Computer Science which demands analytical and technical skills, necessitate a more adaptive learning approach. This study aims to examine the influence of M-Learning on student learning outcomes and identify critical success factors (CSFs) that affect its implementation. The method used is a Systematic Literature Review (SLR) through the planning, implementation, and reporting stages, with a publication range of 2020–2025. Analysis of ten studies showed that M-Learning significantly improved learning outcomes, motivation, and independence, especially for programming-based and applied science materials. This effectiveness is influenced by the quality of the pedagogical design, active learning approaches, and adequate technological support. This finding confirms that M-Learning is a relevant and effective learning strategy, with its success heavily dependent on pedagogical factors and infrastructure readiness.

Abstract

Vehicle rental services still face various obstacles such as limited accessibility, manual management, and the absence of an integrated system. This study aims to develop a multi-platform web and mobile-based application model that can improve the efficiency and transparency of vehicle rental services. The research method used is Research and Development (R&D) with stages of needs analysis, system design, implementation, and testing using the System Usability Scale (SUS). Research data was obtained from direct interviews with rental owners and surveys of 21 potential users. The test results showed an average usability score of 79.4 out of 100, which is in the “good” category. This indicates that the developed application model is superior to the previous models (SDLC and RAD), which were only tested through black-box testing without measuring user usability. With these results, the research successfully introduced an R&D-based application development model that is measurable through SUS, thereby contributing scientifically to improving the effectiveness of the digital vehicle rental system.
