Abstract

Foto sejarah merupakan gambar yang berisikan gambaran di masa lampau. Seringkali, foto sejarah yang ada memiliki kualitas citra yang buruk dikarenakan teknologi kamera yang ada di masa lampau masihlah sederhana. Karena keterbatasan teknologi, foto sejarah yang ada hingga saat ini pun berkualitas rendah dengan warna dominan abu-abu. Kondisi ini mengakibatkan informasi yang terkandung terkadang tidak bisa diterima ataupun menyebabkan salah pemahaman. Image enchancement adalah salah satu operasi dari pengolahan citra yang bertujuan untuk meningkatkan citra dengan memanipulasi parameter-parameter citra. Operasi ini banyak diterapkan pada citra yang memiliki kualitas buruk agar kualitasnya dapat meningkat. Pada penelitian ini akan menerapkan operasi image enchancement pada foto sejarah sehingga kualitasnya dapat meningkat. ada banyak metode yang bisa dilakukan pada image enchancement, diantaranya histogram equalization dan intensity adjustment yang sudah banyak digunakan untuk meningkatkan citra khususnya citra greyscale (abu-abu). Kedua metode tersebut biasa dilakukan pada citra dengan menggunakan Aplikasi Matlab karena penggunaannya yang cukup sederhana

Abstract

Abstract This study aims to analyze the effect of profitability and liquidity on zakat expenditure with company size as a moderating variable. The technique used in selecting the sample is purposive sampling. The samples selected in this study amounted to 7 of 14 Islamic Commercial Banks in Indonesia for the 2011-2020 period. The data collection technique in this study uses the documentation method by searching for data by visiting the official website of Islamic Commercial Banks. Simultaneously, this study shows the results of the profitability variable (ROA) and the liquidity variable (FDR) have a significant positive effect on zakat expenditure on BUS. While partially the results obtained are the profitability variable (ROA) has a significant negative effect, while the liquidity variable (FDR) has no significant positive effect, this study also shows the results that company size as measured by total assets in this study is able to moderate profitability (ROA). but is unable to moderate the relationship between liquidity (FDR) and zakat expenditures at Islamic Commercial Banks.

Abstract

Organic fertilizers contain organic materials such as compost, manure, or other organic waste materials. When organic fertilizers are applied to the soil, they provide an abundant source of nutrients, including nitrogen, phosphorus, and potassium, as well as essential micronutrients. The community service activity program aims to empower farmers with the knowledge and skills to make organic fertilizers from local materials, which not only lower production costs but also improve soil quality and crop yields. The community service activity with the theme "Assistance and Making Organic Fertilizers in Reducing Fertilizer Costs for Farmers in Rowo Gempol Village, Lekok District, Pasuruan Regency" Through the Participatory Action Research method which includes preparation, processing, application, and evaluation, this program has succeeded in improving soil quality and supporting plant growth in the campus green area. Organic fertilizers, produced from campus organic waste such as dry leaves and food scraps, increase soil nutrient content and plant health, and reduce the negative impacts of synthetic chemicals. This activity also involves students in the process of processing and applying fertilizers, providing practical experience and raising awareness of the importance of sustainable agriculture and environmental management. The evaluation results showed a significant positive impact on soil quality and plant growth, with more fertile soil and healthier plants. In addition to the ecological benefits, the program plays an important educational role, by increasing students' understanding of environmentally friendly practices and organic farming skills. The success of this model is expected to be replicated in other villages. so that the benefits of this program can be felt more widely and support the creation of more sustainable agriculture.
