Abstract

Blok Karuh merupakan salah satu area Rencana Pengembangan Seluruh Wilayah (RPSW) yang merupakan eks PKP2B dari PT Arutmin Indonesia. Pelaksanaan reklamasi dalam bentuk revegetasi di blok Karuh telah selesai dilaksanakan dan berangsur-angsur telah selesai dilakukan perawatan hingga tahun 2022. Blok Karuh juga menyisakan Danau Pascatambang sebagai upaya reklamasi bantuk lain. Danau Pascatambang Karuh memiliki potensi yang besar untuk dikembangkan sebagai obyek wisata, keramba jaring apung (KJA) dan sumber air bersih sebagaimana upaya-upaya yang pernah dilakukan. Selain perusahaan, keterlibatan masyarakat dan pemerintah selaku stakeholder juga diperlukan untuk mendukung keberhasilan program-program yang telah diupayakan tersebut. Keberadaan infrastruktur memiliki peran yang sangat vital, khusunya akses jalan sebagai penghubung jalan provinsi ke lokasi Danau Pacatambang yang memakan waktu tempuh dua jam perjalanan.Keberhasilan Danau Pascatambang Karuh dalam mendukung pulihnya ekosistem salah satunya diindikasikan dengan kualitas air danau pascatambang yang telah memenuhi baku mutu lingkungan sesuai Peraturan Gubernur Provinsi Kalimantan Selatan No.36 Tahun 2008 Tetang Baku Mutu Limbah Cair untuk parameter TSS, pH, Fe, Cd, Mn. Kualitas air yang baik ini secara langsung mendukung kesuksesan pertubuhan dan perkembangan biota air. Berdasarkan indeks Shanon Wanner 1994, hasil pengamatan Indeks Keanekaragaman (H’) dari fitoplankton dan zooplankton pada Danau Pascatambang Karuh, masuk dalam kriteria perairan sedang dengan keadaan struktur komunitas stabil, sedangkan dalam Indeks Keseragaman (E’) masuk dalam kriteria perairan sangat baik dengan keadaan penyebaran jenis dalam komunitas sangat merata. Dengan demikian secara umum kondisi ini menunjukan hasil yang baik dan sangat layak untuk kehidupan fitoplankton dan zooplankton. Pengujian fish tissue nekton dengan jenis Ikan Nila (Oreochromis niloticus) yang bersumber dari Danau Pascatambang dilakukan pada tahun 2018 dan 2023, dimana hasilnya tidak menunjukan peningkatan signifikan kadar logam dalam tubuh ikan tersebut. Kegiatan penilaian reklamasi hutan dan reklamasi tambang (JAMREK) di area Pascatambang Karuh telah dilakukan dan kawasan hutannya telah dikembalikan sebagian kepada pemerintah. Hal demikian menjadi indikator keberhasilan pertumbuhan dan perkembagan reklamasi dalam bentuk vegetasi. Perkembangan flora dan fauna pada area reklamasi vegetasi Pascatambang Karuh dan perkembangan biota Danau Pascatambang saling mendukung satu sama lain. Keberadaannya menjadi indikator keberhasilan ekosistem Pascatambang telah pulih dari kerusakaan yang disebabkan selama masa operasi penambangan.

Abstract

Saheb is a web-based pet shop application built with Next.js and Firebase, offering pet product sales and online veterinary consultation services. However, Saheb faces challenges in integrating with third-party applications and system efficiency due to its reliance on Firebase. This study aims to design a REST API using Express.js to enhance modularity, integration, and application performance. The research methodology includes literature review, REST API design using layered architecture principles, and JWT authentication implementation. Evaluation shows that the REST API implementation reduced Firebase resource usage by 57.66% and significantly improved website performance, with average reductions in Speed Index, TBT, and LCP times. The integration of the REST API with third-party applications successfully facilitates interaction without direct Firebase connections. The study concludes that the implementation of REST API improves the efficiency, scalability, and performance of the Saheb application, and opens up opportunities for further development.

Abstract

This study aims to analyze the level of user acceptance towards the Beli.in application using the Technology Acceptance Model (TAM). TAM was chosen as the analytical tool to understand the factors influencing user acceptance of the technology. The study focused on three TAM variables: perceived ease of use, perceived usefulness, and actual use. Data were collected from 32 respondents using a questionnaire. The research findings showed that respondents positively accepted the Beli.in application. The percentage of agreement for the perceived ease of use variable reached 74.06%, indicating that the application is considered easy to use in the process of searching and obtaining information about products. The perceived usefulness variable reached a percentage of 67.5%, indicating that the application is considered beneficial in helping users find daily necessities. However, the actual use variable had a lower percentage at 52.5%, indicating that there is still room to improve application usage. In conclusion, the results of this study provide an overview of user perceptions towards the Beli.in application.

Abstract

This research aims to provide empirical evidence of investor reactions to the disclosure of Management's Discussion and Analysis (MD&A) and Trading Volume Activity (TVA) for companies listed on the Indonesia Stock Exchange from 2015 to 2021. The motivation for this study is the lack of research in Indonesia examining the impact of MD&A on investor decisions, as illustrated by market reactions to stock returns and trading volume activity (TVA). The data used in this research is secondary data obtained from the Annual Reports of companies listed on the Indonesia Stock Exchange (IDX), Refinitiv ESG (Environmental, Social, and Governance) data, and the list of Historical Prices from Yahoo Finance for the period 2015-2021. This study includes 259 data points from 37 companies over the period 2015-2021. Hypothesis testing is conducted using multiple linear regression and non-parametric partial correlation tests. The results indicate that (1) there is no significant positive relationship between MD&A disclosures and stock returns, but (2) there is a significant positive effect of MD&A disclosures on trading volume activity (TVA). This study also incorporates a paired sample t-test to identify differences in stock prices and TVA before and after the disclosure. Implementing these strategies can enhance the productivity and performance of healthcare institutions.

Abstract

This research aims to design an optimal user interface and user experience for language learning applications with the Mobile-First Design approach with the Goal-Directed Design method, which focuses on user goals. User needs analysis was conducted through questionnaires, surveys, and observations to develop usage scenarios. UI design focused on clarity, intuitive navigation, and simple layout, as well as visual appeal. At the UX stage, responsive design principles and user experience testing were applied to ensure that the app could be accessed properly on various devices. After the improvement of the Lingualy application, an evaluation using the System Usability Scale (SUS) resulted in an average score of 74.8, falling into the category of “Acceptable”, with a predicate of “C” and a rating of “Good”. This research concludes that user-centered UI/UX design makes language learning more effective and enjoyable, and enables proficiency without the limitations of time and place.
