Abstract

Abstrak Pelatihan pembuatan akuaponik ini dilaksanakan dengan tujuan untuk meningkatkan keterampilan masyarakat dalam budidaya akuaponik sebagai implementasi ekonomi hijau (SDG’s 8) di Kelurahan Pucangsewu, Kecamatan Gubeng, Surabaya, dengan melibatkan peserta dari karang taruna dan ibu-ibu PKK sejumlah 35 orang. Metode pelatihan meliputi pemaparan teori mengenai konsep akuaponik, demonstrasi pembuatan sistem akuaponik, serta praktek langsung oleh peserta. Hasil dari pelatihan ini menunjukkan bahwa peserta memperoleh pemahaman yang baik tentang prinsip dasar akuaponik dan mampu membuat sistem akuaponik sederhana secara mandiri dari ember. Selain itu, kegiatan ini juga meningkatkan kesadaran masyarakat tentang pentingnya pemanfaatan lahan sempit untuk pertanian perkotaan yang ramah lingkungan (urban farming). Kata kunci: akuaponik; ekonomi hijau; pelatihan; urban farming. Abstract This aquaponics training was carried out with the aim of improving community skills in aquaponics cultivation as an implementation of the green economy (SDG's 8) in Pucangsewu Village, Gubeng District, Surabaya, by involving participants from Karang Taruna and PKK mothers (35 peoples). The training method includes theoretical explanations regarding the concept of aquaponics, demonstrations of making aquaponics systems, and direct practice by participants. The results of this training showed that participants gained a good understanding of the basic principles of aquaponics and were able to make a simple aquaponics system independently from a bucket. In addition, this activity also increased public awareness of the importance of utilizing narrow land for environmentally friendly urban farming. Keywords: aquaponics; green economy; training; urban farming.

Abstract

Al-MCM-41 can be synthesized using kaolin from Bangka Belitung without requiring additional sources of silica or aluminum. The process begins with calcination of kaolin to produce metakaolin, followed by HCl treatment for dealumination, which helps remove impurities and excess alumina. This step is crucial to achieve the optimal SiO₂/Al₂O₃ mole ratio, making the material effective as an adsorbent or catalyst. The hydrothermal process enhances silica polymerization and pore formation due to the strong electrostatic interactions between CTAB and silicate anions, increasing the pore size. The mesoporous structure and SiO₂/Al₂O₃ ratio of Al-MCM-41 are influenced by the CTAB concentration and the extent of dealumination through HCl treatment. In this synthesis, CTAB acts as a structure-directing agent, forming the hexagonal mesoporous framework, while HCl concentration regulates the removal of alumina from kaolin. To optimize the process, HCl concentrations of 2M, 4M, and 6M were tested to evaluate the extent of alumina and impurity removal. The 6M HCl treatment produced a SiO₂/Al₂O₃ ratio of 25.359, which aligns with the commercial Al-MCM-41 standard from ACS Material. Additionally, the iodine adsorption test demonstrated significantly higher adsorption capacity (653.14 mg/g) for Al-MCM-41 compared to kaolin (76.2 mg/g).
