The variables observed included plant height, number of leaves, and leaf length, leaf width, and wet weight. The concentration of liquid biofertilizer had a significant effect on leaf length, leaf width, and wet weight of plants aged 35 HST, had no significant effect on plant height, number of leaves aged 7, 14, 21, and 28 HST. The best dose of liquid biofertilizer treatment was at a concentration of 150 ml (P2). The provision of biochar had a significant effect on leaf length, leaf width, and plant wet weight at the age of 35 HST, had no significant effect on plant height and number of leaves at the ages of 7, 14, 21, and 28 HST. The results showed that there was a significant interaction on leaf length, leaf width, and plant wet weight, a significant interaction on leaf length, leaf width, and plant wet weight at the age of 35 HST, while other parameters had no significant effect. The interaction between the concentration of liquid fertilizer 150 ml (P2) with 3 kg of biochar (B3) was the best treatment combination.

The CRISPR-Cas9 technique is a contemporary technology that has transformed the process of genetic modification, allowing scientists to target genomes in living organisms with precision and simplicity. Numerous practical applications of significant importance, including the introduction of new genes into living cells, are facilitated by the CRISPR-Cas9 system's advanced level of gene targeting, precision, and simplicity of use. An enigmatic process involving repeated DNA sequences in E. coli initiated the emergence of this CRISPR-Cas9 mechanism. After observing this phenomenon in bacteria, scientists initiated an investigation into its function. It was noted that E. coli employs it as a self-defence mechanism against bacteriophage attacks and plasmids. CRISPR-Cas9, a novel method for genetic modification, was created as a result of this investigation. This system has been re-engineered by scientists to be more broadly applicable, allowing for the modification of the genetic code of virtually any organism, surpassing the scope of self-defence. The CRISPR-Cas9 system-based gene editing mechanisms have the potential to produce substantial results that were previously difficult to achieve. Nevertheless, the question of genetic modification through the application of this technology prompts debates and demands for the resolution of the ethical, social, and legal issues that are associated with its application. The potential applications of the CRISPR-Cas9 system are seemingly boundless.

Juvenile criminal justice in Indonesia is an important aspect of the justice system that focuses on protecting the rights of children in conflict with the law. One of the efforts regulated in Law Number 11 of 2012 concerning the Juvenile Criminal Justice System (SPPA) is diversity, which aims to prevent children from the judicial process that can harm their future. This study aims to analyze the protection of children's rights in the criminal justice process, as well as the implementation of diversity in the juvenile criminal justice system in Indonesia. The method used in this study is a qualitative approach with descriptive analysis, through literature studies and interviews with various related parties, such as judges, prosecutors, and community counselors. The results of the study indicate that although there are efforts to protect children's rights in criminal justice, the implementation of diversity still faces a number of challenges, including a lack of understanding among law enforcement officers, limited facilities, and a mismatch between policies and practices in the field. This study suggests the need to increase the capacity of law enforcement officers and other stakeholders in understanding and implementing diversity efforts optimally, as well as the need for policy evaluation to improve the effectiveness of child protection in criminal justice.

This study aims to analyze errors in the use of Enhanced Spelling (EYD) in writing explanatory texts by grade 6 elementary school (SD) students. Explanatory text is an important type of text in learning Indonesian, but students often make mistakes in using EYD when writing this text. This research uses descriptive qualitative methods with content analysis and interview techniques. Data were obtained from explanatory texts written by 6th grade elementary school students and the results of interviews with the principal, homeroom teacher, and 15 students. The research results show that students still make many mistakes in using EYD, especially in the use of capital letters, punctuation and writing words. This error is caused by students' lack of understanding about EYD, lack of practice in writing explanatory texts, lack of teacher attention to EYD teaching, and lack of support from the home environment. This research recommends that teachers pay more attention to EYD teaching, provide regular explanatory text writing practice to students, increase collaboration with parents, and create a learning environment that is conducive to the development of students' writing skills.

This research aims to increase efficiency in monitoring student attendance at Madrasah I'dadiyah Salafiyah Syafi'iyah by utilizing the K-Means Clustering analysis method. Monitoring student attendance is still carried out conventionally, so it often takes time and is less effective in identifying overall student attendance patterns. For this reason, in this research, student attendance data collected from the madrasa attendance system was analyzed using K-Means Clustering, a machine learning technique that can group students based on their attendance patterns. This process produces several groups which make it easier for the madrasah to identify students who frequently attend, rarely attend, or frequently do not attend. In this way, madrasas can take more appropriate steps in dealing with attendance problems, such as paying special attention to students who are often absent. The results of this research indicate that the application of K-Means Clustering can increase the efficiency of attendance monitoring and provide a stronger basis for decision making to improve the attendance system at the I'dadiyah Salafiyah Syafi'iyah madrasah.
