Abstract

At the Office of the Ministry of Religion of East Kotawaringin Regency, the administrative process of registering zakat and waqf is still done manually, so that for less than optimal public services it takes a long time in the process, there are also obstacles to delays in making reports and the form of data storage which is still in the form of documents. archived and so that the data search process becomes slow. This will hamper the quality of service to the community. Therefore, it is necessary to design a system that can assist the process and provide information regarding the registration of zakat and waqf. By doing this research, it is hoped that the needs of the latest system and problems that often occur in data processing at the Sampit Religious Affairs Office, East Kotawaringin Regency by using the information system This website-based system can be handled properly, so that it can improve the performance of the parties involved in the data processing process in the form of the administration of zakat and waqf registration and can improve the service performance of the Sampit Religious Affairs Office, Kotim Regency

Abstract

Biofouling ada jenis biota yang menempel pada suatu substrat. Banyaknya biofouling yang menempel pada badan kapal akan menyebabkan kerusakan dan memperpendek usia pakai kapal. Penelitian ini bertujuan untuk membandingkan biofouling pada kapal kayu dan kapal fiber milik nelayan di Wolo, Kabupaten Kolaka. Pengambilan data biofouling dilakukan pada Bulan Oktober 2020 di di pesisir pantai Wolo, Kabupaten Kolaka menggunakan metode transek kuadrat yang meliputi data keanekaragam dan keseragaman biofouling pada dua jenis kapal serta parameter perairan. Hasil yang diperoleh yaitu biofouling jenis Balanus sp. ditemukan paling dominan pada kedua jenis kapal dan jenis Littorina scabra dan M. withersii ditemukan sebagai jenis minoritas pada kapal fiber. Hasil yang diperoleh yaitu pada kayu ditemukan jenis Balanus sp dan L. scabra dengan nilai keanekaragaman 0,009 dan keseragaman 0,013. Sedangkan pada fiber ditemukan jenis Balanus sp., L. Scabra dan M. withersii dengan nilai keanekaragaman 0,223 dan nilai keseragaman 0,203. Secara keseluruhan, ditemukan lebih banyak jenis biofouling pada kapal fiber namun ditemukan lebih banyak individu pada kapal kayu.Kata kunci: Keanekaragaman, Biofouling, Kapal Kayu, Kapal Fiber, Wolo.

Abstract

Fusarium oxysporum f.sp. cubense (Foc) is an important pathogenic fungus that causes Panama disease in banana. One approach to overcome this problem is to utilize secondary metabolites from Trichoderma sp. This research was conducted to determine the effect of administering secondary metabolites from Trichoderma sp. against pathogen Foc. These metabolites were applied at concentrations of 10%, 20%, and 30%, 40% alongside a fungicide active ingredient of phosphoric acid 400 SL. This study used a Completely Randomized Design with 6 treatments 4 repetition. The parameters observed included colony diameter and percentage of inhibitory. The extraction of secondary metabolite isolation could be obtained as much as 500 ml with reddish brown, thick and odorless characteristics. Secondary metabolites showed a significant effect in inhibiting the growth of the pathogen Foc. The results showed the 10% concentration proved to be the most effective to inhibit pathogen Foc, resulting in the smallest colony diameter of 0.58 cm and an in vitro inhibition rate of 90.73%.
