Vertiqua is an innovation in vertical cultivation on limited land and water. Vertiqua continues to be developed to be effective in cultivating fish. This research aims to examine the effectiveness of nitrogen distribution in vertiqua using biofical top filters. The analysis used is quantitative analysis by calculating and testing the data that has been collected. Total nitrogen feed input, total nitrogen wasted, and percentage of nitrogen absorption were calculated using existing formulas. Comparative testing using the T – test on the Mini Tab application was carried out to test the effectiveness of nitrogen absorption. The research results showed that nitrogen absorption in the vertiqua using the top biofical filter was effective, ranging from 198,12 – 200,89 mg/l. Nitrogen absorption in the vertiqua without using a biofical top filter ranges from 42,75 – 43,35 mg/l. The distribution value of effective nitrogen absorption in vertiqua using the top biofical filter is shown by a P value <0,05. Vertiqua with a biofical top filter is also able to reduce nitrogen levels so that fish survival is good.

Women's empowerment is an important component in sustainable development and social welfare. Muhammadiyah, as one of the largest Islamic organizations in Indonesia, has played a significant role in efforts to empower women through its autonomous organizations, namely 'Aisyiyah and Nasyiatul 'Aisyiyah. This article aims to examine the role of these organizations in improving the quality of life of women in Indonesia. This research uses a qualitative descriptive method with secondary data analysis from various relevant sources. 'Aisyiyah, founded in 1917, focuses on empowering women through education, health and activities socio-economic. Various programs have been implemented, including establishment educational institutions, health clinics, and skills training programs. Nasyiatul 'Aisyiyah, founded in 1931, targets young women with programs that include education, skills training, and women's rights advocacy

 Digitalization is not only developing in companies and public school but is also developing in Madrasah schools such as what happened at Madrasah MA Al-Djufri which is located in the Blumbungan, Pamekasan, based on private schools that currently have minimal use of the system. The service here will provide a website combined with Excel and also the application of QR Codes in implementing daily attendance. The existing opportunities must be used as a spark for enthusiasm to improve and innovate so that they can progress and develop. This activity seeks to provide a solution for private madrasas that do not yet have a website. This service through practical work uses a participatory action research approach. Technically, it is carried out through five stages of competition-based service which include preparation, training, mentoring, competition, and appreciation. The real result of this service activity is the existence of a website in the form of a QR code and Excel to support progress at MA Al-Djufri which previously was still not good. As many as 94% of madrasas stated that in general the implementation of community service activities was carried out very well.
