This research aims to develop an expert system that can diagnose diseases related to brain tumors using the Case Based Reasoning (CBR) method. The CBR method works by comparing new cases with previous cases that have been stored in the database to provide appropriate diagnoses and treatment recommendations. This system is designed to assist medical personnel in analyzing patient symptoms, thus speeding up the process of identifying the type of brain tumor. In addition, the system is also equipped with a knowledge base obtained from real cases that have been validated by medical experts. Test results show that the diagnostic accuracy of this system reaches a fairly high level, especially in detecting frequently encountered types of brain tumors. Thus, this system has the potential to be an effective tool in the medical diagnosis process, especially in patients who show symptoms of brain tumors.

Memory ability plays an important role in achieving optimal results in cognitive aspects, especially in the context of education which is measured through learning achievement. One of the methods used to hone memory is through memorizing the Qur'an. A study was conducted to examine the effect of the ability to memorize the Qur'an on improving cognitive aspects in tahfidz class students at Bustanul Ulum High School in Central Lampung. The research method used was quantitative involving 33 participants. Data were collected through observation, questionnaires to assess the ability to memorize the Qur'an, and documentation of students' report cards. The results showed that the ability to memorize the Qur'an had a significant effect on improving students' cognitive aspects, with an R Square value of 29.7%. That is, about 29.7% of the improvement in cognitive aspects can be explained by the ability to memorize the Qur'an. Other factors outside the method of memorizing al-Qur'an also contribute to the increase.

This study investigates how capital structure and profitability influence the value of PT Astra Agro Lestari Tbk. It employs a quantitative approach using numerical data, specifically analyzing the company's financial reports from 2012 to 2021. The findings indicate that capital structure significantly affects the company's value, with a T-test result showing a calculated value of 5.686, which exceeds the t-table value of 1.89458, and a significance level of 0.031 (less than 0.05). Profitability also has a significant impact, with a calculated value of 5.686 surpassing the t-table value of 1.89458 and a significance level of 0.001 (less than 0.05). This suggests that both capital structure and profitability individually affect the company's value. Additionally, when considered together, capital structure and profitability have a combined significant impact on firm value, with a significance level of 0.002 (less than 0.05) and a calculated F-value of 17.413, which is greater than the F-table value of 4.74. This confirms that both factors together significantly influence the company's value

Galah shrimp is one type of freshwater shrimp that has great potential for cultivation. One of the obstacles to the growth of king prawns is water quality. This study was conducted to determine the effect of the installation of Vegetable Floating Raft (VFR) on the growth of king prawns (Macrobrachium rosenbergii). This study was conducted using the t-test method, with control and Vegetable Floating Raft treatments. The results showed that the growth pattern of weight and length of king prawns in each treatment was relatively the same. However, the daily weight growth rate of king prawns in the control treatment was greater at 3.36%, compared to the treatment of Vegetable floating raft at 1.26%, while the daily length growth rate of king prawns in the control treatment was 0.86%. The daily length growth rate in the Vegetable floating raft treatment was smaller at 0.61%. During the study the value of the degree of survival of the control treatment was 95%, while in the treatment of Vegetable floating raft the percentage of the degree of survival of king prawns was 62%. Based on the results of visual observations seen the rest of the feed and the rest of the skin during molting. It is suspected that shrimp are stressed due to changes in water quality characterized by increased ammonia levels in the last maintenance week caused by the death of kale plants in the maintenance medium.
