Abstract

This study aims to evaluate the effectiveness of KCl-modified Sarulla natural zeolite in removing ammonium ions from aqueous solutions. The zeolite was modified by soaking in 0.5 M (ZA05) and 1.5 M (ZA15) KCl solutions for 24 hours at a solid/solvent ratio of 1:3 (weight/volume). The adsorption process was conducted in batch mode using an orbital shaker at a speed of 100 rpm, with contact times ranging from 0 to 210 minutes. The initial ammonium ion concentration was 100 mg/L, and the analysis was performed using a UV-visible spectrophotometer. The results showed that ZA05 and ZA15 adsorbents achieved ammonium ion removal efficiencies of 14.62% and 12.29%, respectively. Adsorption isotherm analysis using the Langmuir and Freundlich models demonstrated a good fit with the equilibrium data, with ZA15 exhibiting a higher maximum adsorption capacity than ZA05. This study confirms the potential of KCl-modified Sarulla natural zeolite as an effective adsorbent material for wastewater treatment.

Abstract

Lake Toba as the largest volcanic lake in Southeast Asia faces a serious threat in the form of water pollution due to the activities of Floating Net Cages (KJA). This study aims to evaluate the status of water quality in the waters of Lake Toba, especially in Tongging Village, Karo Regency. The evaluation was carried out using the STORET method approach. Water samples were taken at three different time conditions (before, during, and after feeding) at five strategic points representing KJA, around KJA, and river inlets. The results showed that the concentrations of phosphate and nitrate had exceeded the quality standards of PP No. 22 of 2021, reaching 0.072 mg/L and 9.950 mg/L, respectively. The highest STORET method score was -35, indicating severely polluted water conditions. These findings emphasize the need for sustainable fisheries management in Lake Toba.

Abstract

This study identifies common contrastive errors in English grammar made by Indonesian EFL learners, along with their causes and solutions. Such errors often arise from structural differences between the learner's first language (L1) and English (L2), potentially leading to misunderstandings. Using a descriptive qualitative research design, data were collected from eleven undergraduate students in the English Education program at Universitas Islam Negeri Sumatera Utara. Data collection methods included grammar tests and surveys to explore the underlying causes of errors. Analysis revealed that common errors included tense usage, subject-verb agreement, article usage, and preposition errors. These mistakes are attributed to language transfer, interlanguage phenomena, and a lack of understanding of English structures. The study recommends teaching strategies such as drilling activities, corrective feedback, context-based learning, and comparative grammar analysis to mitigate these errors. By implementing these approaches, it is hoped that learners will enhance their understanding and application of English grammar more effectively, ultimately improving their communication skills in English.

Abstract

Syirkah and mudharabah are two forms of partnership contracts widely applied in financing productive business activities within Islamic financial institutions. Both contracts are based on the principles of profit and loss sharing and the prohibition of riba, which promote fairness and ethical economic practices. However, their implementation in society still faces challenges due to limited understanding of their conceptual distinctions, mechanisms, and risk-sharing characteristics. This article describes the concepts of syirkah and mudharabah, including their essential elements and operational requirements, as well as their application in productive financing schemes. In syirkah, all partners contribute capital and/or managerial efforts and are entitled to profits according to the mutually agreed ratio, while losses are borne proportionally based on each partner’s contribution. In contrast, mudharabah involves a collaboration in which the investor provides capital and the entrepreneur manages the business. Profits are distributed based on a predetermined profit-sharing ratio, while financial loss is borne solely by the investor, as long as the entrepreneur is not negligent or in breach of trust. The analysis indicates that both contracts have significant potential to support the development of micro, small, and medium enterprises (MSMEs) and strengthen the Islamic economic system. Nevertheless, the selection of the appropriate contract must consider the business characteristics, the capabilities of the parties involved, and the level of risk they are willing to bear. With accurate understanding and implementation, syirkah and mudharabah can serve as transparent, equitable, and sharia-compliant financing solutions for the community.
