Asam sitrat terdapat melimpah di alam dan dihasilkan sebagai salah satu zat antara pada siklus asam sitrat saat karbohidrat dioksidasi menjadi karbondioksida. Asam sitrat merupakan penyebab rasa asam pada berbagai buah seperti jeruk, nanas dan pir. Karena kelarutannya yang tinggi, rasanya yang enak dan toksisitasnya yang rendah maka asam sitrat banyak digunakan dalam industri makanan, minuman dan obat-obatan. Salah satu metode yang digunakan untuk produksi asam sitrat adalah dengan metode fermentasi. Aspergilus niger merupakan salah satu mikroorganisme yang dapat digunakan pada proses produksi asam sitrat. Produksi asam sitrat pada penelitian ini dilakukan dengan tahap pemeliharaan A. niger pada media agar miring, aktivasi kultur A. niger dalam inokulum dan produksi asam sitrat dalam media fermentasi yang mengandung 20, 25, 30 dan 35% konsentrasi molase dengan metode biak rendam. Analisis yang dilakukan mencakup perubahan pH, berat kering sel, konsumsi gula pereduksi, serta konsentrasi asam sitrat yang dihasilkan. Hasil penelitian ini menunjukkan bahwa asam sitrat paling banyak diproduksi pada media yang mengandung 30% molase, yaitu diperoleh 85,8 g/L asam sitrat.

Poli-γ-asam glutamat (PGA) dan hasil degradasinya aman bagi manusia sehingga dapat dimanfaatkan sebagai bahan pengental, pelembab, pelepas berjangka atau sebagai pembawa obat. Meskipun banyak digunakan pada berbagai bidang industri, bahan ini masih diimpor dari luar negeri. Oleh karena itu, perlu dikembangkan suatu proses untuk memproduksi PGA secara efektif dan efisien. Penelitian ini dilakukan untuk menentukan konsentrasi optimum amonium sulfat sebagai sumber nitrogen untuk menghasilkan PGA dalam jumlah yang banyak. Produksi PGA dilakukan dengan fermentasi menggunakan bakteri Bacillus subtilis B112. Analisis yang dilakukan selama proses fermentasi meliputi pengukuran pH, derajat kekeruhan, berat kering sel dan viskositas media. Isolasi PGA dilakukan dengan tahapan sentrifugasi, pengendapan dengan metanol, dialisis dan liofilisasi. PGA yang telah diisolasi kemudian ditentukan berat molekulnya dengan meggunakan SDS-PAGE, sedangkan komposisi asam amino PGA ditentukan dengan menggunakan metode KLT. Hasil penelitian menunjukan bahwa konsentrasi ammonium sulfat yang optimum untuk menghasilkan PGA adalah 0,75% b/v. PGA yang diperoleh dengan variasi 0,75% amonium sulfat sebanyak 61,6 mg. Penentuan berat molekul dengan menggunakan SDS-PAGE menunjukan bahwa PGA yang diproduksi oleh B. Subtilis B112 memiliki berat molekul sekitar 205 kDa. Kata Kunci: Asam L-glutamat, amonium sulfat, B. Subtilis B112, PGA

There are quite a lot of coffee shops in Palembang. There are 90 active Coffee Shops which can be seen from the Instagram account @liburhariselasa as a Coffee Shop review in Palembang, this is because there are many coffee lovers/visitors in the city of Palembang. With so many visitors coming to the coffee shop, it is not surprising that the profits earned by coffee entrepreneurs are so high, even the capital spent does not reach the income from the business. However, there are still entrepreneurs who do not understand and do not understand the zakat that must be paid on their income, there is income zakat or trade zakat that must be paid when the business has reached the calculation in Islamic Sharia. From the previous study, researchers were interested in researching the implementation of trade zakat by coffee shop business actors in Palembang.The type of research used in this research is qualitative research with a descriptive approach when presenting situations studied in the field, identifying problems that arise, and analyzing them in detail based on factual and accurate data. This research also uses Field Research or field research which means research in which data collection focuses on informants who have been determined.From the results of this research, it was noted that there were several coffee entrepreneurs in the city of Palembang who did not really understand the obligation to pay zakat on trade from an Islamic perspective. However, there are also business actors who understand their obligation to pay trade zakat, and have also carried out zakat payments in accordance with an Islamic perspective. Apart from that, there are also business actors who have paid trade zakat but the payment is not correct and not in accordance with Islamic law. Business actors who do not understand do not pay trade zakat in accordance with an Islamic perspective. In its implementation, the practice of paying trade zakat that has been carried out by the owner of Tjipta Djaja and Kopi Cepat is correct and in accordance with the ordered zakat payments, therefore, the payments made by coffee entrepreneurs are said to be in accordance with Islamic law. Meanwhile, Floor 4 Coffee already understands the understanding of trade zakat. but has not done so because his income has not met the nisab for calculating trade zakat. There are also coffee shop business actors who do not fully understand the payment of zakat on trade such as Dialek and Beruang Coffee.

This study aims to examine the application of a maritime ethnoscience approach in science learning through a systematic literature review (SLR) of publications from 2017 to 2025. Of the 60 articles searched through Google Scholar and Scopus, 21 passed the selection process based on the inclusion criteria. The analysis shows that most studies focused on junior high school students, utilizing direct ethnoscience learning models, 4D development, and Problem-Based Learning (PBL). This review confirms that the application of maritime ethnoscience is effective in improving students' conceptual understanding, scientific literacy, critical thinking skills, and awareness of the marine environment. However, the limited concentration of research on a single educational level suggests opportunities for further study at the elementary, high school, and tertiary levels. These findings emphasize the urgency of integrating maritime local wisdom into science learning, not only to strengthen cultural identity but also to equip students with 21st-century competencies.

In economic activity appeared the three actors in it; State, the private sector, and communities that each had different bargaining positions, such as access to capital and political access with respect to natural resources such as land that limited. Changes in economic perspective view toward the rapidly developing ground. Currently the ground further highlighted its function as capital assets and commodities, the mastery and utilization of land depended on market mechanisms. This meant that capitalist contributed to intervene the mastery and ownership of land. This affected concentrated on a handful of people who had big capital with more tendency to speculative rather than productive. Results of the research which was found that Rahman had a general idea that the fundamental principle of the whole body of norms or rules in economic activity was turn the attitude of altruism, namely the altruistic rather than personal interests. In particular, first; Rahman rationale was, as a basic theological importance of managing in the form of hard work to meet the livelihood so that they did not fail or lagging from others in the struggle for survival. Rahman explained that the emphasis on man's efforts to obtain a source of livelihood was one of the fundamental economic principles in Islam; if this principle ignored it will meet with failure causing poverty and starvation. Secondly, in terms of basic thoughts of Rahman on the corporate governance of the land of Islam over to an aspect of the economic approach based on the production of the agricultural sector, ranging from the certainty of land ownership which affected toward the result of increased production, land distribution, the production of the agricultural sector which emphasized the holding of insurance with the principles of " mutuality "and" cooperative "as both a preventative and a recovery in production activities, improvement of human resources (HR), and the determination of minimum wages by using a calculation in accordance with the basic necessities. Third, based on the basic thoughts, Rahman had relevance to the corporate governance of land in Indonesia, the relevance contained in the constitution or the Indonesian positive laws that applied today.
