Abstract

This study aims to evaluate the operational performance of a 7000-liter fiberglass biodigester that was revitalized and modified at the Power and Agricultural Machinery Laboratory, Faculty of Food Technology and Agroindustry, University of Mataram. The fiberglass biodigester was developed as an alternative to conventional concrete biodigesters, which are prone to structural damage and exhibit limited operational efficiency, particularly in earthquake-prone regions. The research was conducted as an observational case study through performance monitoring of the biodigester during 40 days of continuous operation following system repair and modification. Cow manure was used as the substrate, mixed with water at a 1:2 ratio (by volume). The monitored parameters included fermentation temperature, substrate pH, gas pressure, daily biogas volume, gas composition, and combustion quality. The results showed that the biodigester operated stably at temperatures ranging from 27 to 31 °C and near-neutral pH conditions, with a maximum daily biogas production of 4.43 m³/day and an average of 1.73 m³/day throughout the monitoring period. The methane content ranged from 52 to 61%, while hydrogen sulfide concentration was reduced to approximately 150 ppm after gas purification, indicating that the biogas was suitable for combustion with a heating value of up to 21 MJ/m³. These findings demonstrate that the fiberglass biodigester exhibits good operational performance and has strong potential for application as a renewable energy system at campus and community scales, supporting sustainable livestock waste management.

Abstract

This research was motivated by the many complaints from people memorizing the Qur'an. They find it difficult to memorize and carry it out. There is a method called the Takrir method for memorizing the Qur'an, as an effort to improve and maintain memorization so that it remains embedded in the heart. Based on the background above, the problem formulation can be taken, what is the process of implementing the Takrir method in memorizing the Al-Qur'an and what results are achieved in implementing this method in memorizing the Al-Qur'an and what is the evaluation practice. This research uses a qualitative descriptive method with a phenomenological approach. To collect data using interview, observation and documentation methods. In analyzing the data the author uses stages: reducing data, displaying data and drawing conclusions. The research results show: First, the process of implementing the Takrir method in memorizing the Qur'an at the Tahfidhz Darul Fithrah Tawangsari cottage is going well, this is based on the reality of implementing memorizing the Qur'an using the Takrir method. However, it is still not perfect, as can be seen from the several problems it faces. Second, the results that have been achieved from the Takrir method are good and successful, the indication is that Tahfidz students can memorize half a Juz of the Qur'an per month, this has met the target. As for the evaluation of the implementation of the Takrir method, deliberations will be carried out every 3 months according to the need to find out the ma'had targets that have been formulated.
