Abstract

This research was conducted at Malaga Beach, Siwalu Banua II Village, Gunungsitoli Idanoi District, Gunungsitoli City, North Sumatra Province, with the aim of determining the feasibility of beach tourism objects from the limiting factors of the Tourism Suitability Index Value (IKW). This research was carried out for 1 month, namely from the beginning of March to the beginning of April 2021. The method used in this research was the purposive sampling method. The analysis parameters used are depth, beach type, beach width, bottom water material, current speed, beach slope, water brightness and beach land cover. Based on the results of observations, it shows that the Malaga Beach tourist attraction has good potential because it has a wide sand beach and has not big waves. The research results show that the Tourism Suitability Index (IKW) value is 58.16% and is classified as S3 (Conditionally Suitable) level of suitability. This value provides information that the tourist attraction is in the appropriate category conditionally for the feasibility of its development. The condition for the development in question is the appropriate use of potential, namely the potential width or breadth of the beach as well as the presence of shady pine and palm trees by creating comfortable shelters such as tourist tents, gazebos, children's toys. Thus, Malaga Beach, Siwalu Banua II Village, Gunungsitoli Idanoi District, Gunungsitoli City, North Sumatra has good potential to be developed into a recreational tourism and children's play location, but is not suitable for swimming tourism.

Abstract

4A zeolite complex derived from coal has been successfully synthesized through the preparation of fractionated samples, analyzed using atomic absorption spectrophotometry (AAS), resulting in a chemical composition of silica (SiO2) 24.78% and aluminum oxide (Al2O3) 29.60%. The fly ash produced from this fractionation is used as the base material for the synthesis of 4A zeolite. The fly ash is reacted with sodium hydroxide (NaOH) at room temperature, yielding a gel that is subsequently crystallized into 4A zeolite through a reflux process. The resulting zeolite crystals are then supplemented with Al2O3 and disodium dihydrogen ethylenediaminetetraacetate (Na2EDTA) as sources of aluminum to achieve a molar ratio of Si/Al = 1.42. Optimal quality 4A zeolite crystals were obtained from the synthesis of 5.9351 g of medium fraction fly ash, along with 1 g Al2O3, 4 g NaOH, and 0.569 g Na2EDTA. Infrared (IR) characterization results indicate that the optimal 4A zeolite from medium fraction fly ash is characterized by crystals with the addition of 1.5 g of Al2O3. Wide absorption bandwidths are typically caused by large spectral line widths, which can occur if a significant amount of energy is absorbed by various vibrational modes, assuming that excess Al2O3 leads to the formation of functional groups that contribute to the same band. A peak at a wavelength of 564 cm-1 indicates double ring stretching vibrations, while a peak at 661 cm-1 indicates symmetric stretching vibrations of the zeolite framework. Meanwhile, peaks at wavelengths of 3460.86 cm-1 and 974.71 cm-1 indicate detected O-H absorption

Abstract

The high cost of feed is a major challenge in sustainable fish farming. This study aims to examine the optimization of Black Soldier Fly (Hermetia illucens) larvae or maggots as an alternative feed to improve the growth efficiency of environmentally friendly farmed fish. The study employs a quantitative approach through growth tests on catfish (Clarias gariepinus) fed a maggot-based feed formulation produced using various organic waste media. Results indicate that substituting fish meal with maggot meal up to 50% yields significant improvements in daily growth rate and feed conversion efficiency. Maggot culture was also proven to optimally utilize domestic and market organic waste, thereby contributing dual benefits to environmental management. This research underscores the importance of developing local alternative feed for sustainable aquaculture while supporting community-based circular economy initiatives.

Abstract

Feed is an important factor in cultivating catfish (Clarias sp.), which affects the survival and growth of fry. Catfish growth is greatly influenced by feed quality, including nutrition, digestibility and feed utilization. Fermented feed is one of the innovations developed to improve feed quality. Fermented feed has become an attractive alternative to improve feed quality and growth efficiency. This article aims to explore the effect of fermented feed on the survival and growth of catfish fry by reviewing various previous studies. The method used is a literature review by collecting research results from various published scientific articles. The research results show that the use of fermented feed in catfish cultivation can increase growth, digestibility and feed efficiency. Further research is needed to explore optimal dosage and composition.

Abstract

This study aims to analyze the role of probiotics in supporting the sustainability of fish farming systems. The study was conducted using a literature analysis method from various scientific sources, including journals, academic books, and other scientific works. Probiotics are proven to have significant benefits in increasing feed efficiency, improving water quality, and increasing fish resistance to disease. The study results show that probiotics can reduce ammonia levels by 40%, increase feed conversion efficiency (FCR) by 25%, and increase fish survival rates by 90%. In addition, the use of probiotics can reduce dependence on antibiotics and chemicals, making it more environmentally friendly. The conclusion of this study is that probiotics are an effective solution to improve production efficiency while maintaining environmental sustainability in fish farming. However, further research is needed to optimize the type and application of probiotics that suit various aquaculture systems.

Abstract

Pertumbuhan populasi dunia dan kebutuhan pangan yang semakin meningkat merupakan tantangan global kompleks. Untuk mengatasinya, inovasi teknologi akuakultur berkelanjutan, seperti sistem akuaponik, telah menjadi fokus utama dalam upaya memenuhi kebutuhan pangan yang meningkat. Sistem akuaponik mengintegrasikan budidaya ikan dengan pertumbuhan tanaman secara terintegrasi, menciptakan siklus alami di mana ikan menghasilkan limbah yang diperlukan sebagai sumber nutrisi bagi tanaman, sementara tanaman membersihkan air untuk ikan. Dalam jurnal ini, kami membahas pemanfaatan sistem akuaponik untuk meningkatkan produksi ikan dan tanaman secara berkelanjutan. Sistem akuaponik menawarkan berbagai manfaat, antara lain efisiensi penggunaan air yang tinggi, pengurangan limbah, dan peningkatan produktivitas. Penelitian ini dilakukan melalui tinjauan pustaka terhadap artikel ilmiah, jurnal, dan publikasi terkait inovasi teknologi akuakultur berkelanjutan dan pemanfaatan sistem akuaponik. Data dan informasi yang diperoleh dianalisis dan disajikan untuk mendukung tujuan penelitian ini. Dalam hasil dan pembahasan, kami menjelaskan prinsip dasar dan manfaat akuaponik, serta faktorfaktor yang mempengaruhi produksi ikan dalam sistem akuaponik, seperti ketersediaan nutrisi, kualitas air, suhu lingkungan, kepadatan ikan, dan manajemen pakan. Diharapkan bahwa penelitian ini memberikan panduan dan pemahaman yang lebih baik tentang potensi dan keuntungan penggunaan sistem akuaponik dalam konteks akuakultur berkelanjutan Kata kunci: Akuakultur Berkelanjutan, Akuaponik, Inovasi Teknologi, Produksi Ikan dan Tanaman
