Protein and carbohydrate content in macroalgae are required to optimize the utilization of macroalgae from Sepanjang Beach. This study aims to determine the protein and carbohydrate content of macroalgae at Sepanjang Beach, Yogyakarta. This research was conducted in August-September 2020. The research materials included macroalgae of Ulva lactuta, Palmaria palmata, Sargassum crassifolium, Gelidium spinosum, Gelidiella acerosa, and Gracilaria verrucosa. The macroalgae was collected by purposive sampling in the intertidal zone of Sepanjang Beach. The protein content was analyzed by Biuret method, while the carbohydrate content by the difference method. Results showed that the highest protein and carbohydrate content was found in G. spinosum in central part of Sepanjang Beach at 3.08% and 19.38%, respectively. Based on these results, G. spinosum has the potential to be developed in various processed products with further research.

Penelitian ini bertujuan untuk mengetahui aktivitas antioksidan berbagai jenis makroalga di Pantai Sepanjang, Kabupaten Gunungkidul, Yogyakarta. Penelitian ini dilaksanakan di Pantai Sepanjang, Kabupaten Gunungkidul, Yogyakarta pada bulan Agustus 2020. Jenis makroalga yang ditemukan pada saat penelitian antara lain Ulva lactuca, Palmaria palmata, Sargassum crassifolium, Gelidium spinosum, Gelidiella acerosa, dan Gracilaria verrucosa. Metode yang digunakan dalam penelitian ini adalah deskriptif eksploratif. Pengambilan sampel makroalga dilakukan secara purposive sampling meliputi bagian timur, tengah dan barat Pantai Sepanjang. Analisis aktivitas antioksidan menggunakan metode DPPH (1,1-diphenyl-2-picrylhydrazyl). Hasil analisis menunjukan bahwa potensi aktivitas antioksidan tertinggi terdapat pada Gelidiella acerosa yang berada di bagian tengah Pantai Sepanjang dengan nilai IC50 sebesar 22,407 g/ml. This research aimed to analyze antioxidant activities from various types of macroalgae. Sample collection was taken at Sepanjang Beach, Gunungkidul District, Yogyakarta in August 2020. Various types of macroalgae were found are: Ulva lactuca, Palmaria palmata, Sargassum crassifolium, Gelidium spinosum, Gelidiella acerosa, and Gracilaria verrucosa. A method of descriptive exploratory was used in this research. Macroalgae samples were collected by purposive sampling from the eastern, central and western area of Sepanjang Beach. Antioxidant activities were carried out using DPPH method. The results showed that fresh Gelidiella acerosa which is located in the middle of Sepanjang Beach, has the highest antioxidant activities with IC50 value 22.407 g ml-1.

ANALISIS KANDUNGAN FITOKIMIA PADA BERBAGAI JENIS MAKROALGA DI PANTAI JUNGWOK, KABUPATEN GUNUNGKIDUL, YOGYAKARTA (Analysis of Phytochemical Contents in Various Types of Macroalgae at Jungwok Beach, Gunungkidul District, Yogyakarta) Heny Budi Setyorini; Ernastin Maria

Penelitian ini bertujuan untuk mengetahui kandungan fitokimia pada berbagai jenis makroalga di Pantai Jungwok, Kabupaten Gunungkidul, Yogyakarta. Penelitian ini dilaksanakan di Pantai Jungwok, Kabupaten Gunungkidul, Yogyakarta. Materi penelitian ini adalah makroalga (Ulva sp., Gracillaria sp., dan Boergesenia sp). Metode yang digunakan dalam penelitian ini adalah survei dengan pendekatan kualitatif. Teknik pengambilan sampel makroalga menggunakan purposive sampling. Lokasi pengambilan sampel makroalga berada di bagian timur, tengah dan barat Pantai Jungwok. Analisis skrining fitokimia dilakukan dengan uji kualitatif. Analisis skrining alkaloid menggunakan metode Culvenor Fitzgerald, sedangkan untuk steroid dan terpenoid menggunakan metode Liebermann-Buchard Test, pada fraksi air yang terbentuk dilanjutkan dengan uji flavonoid, fenolik dan safonin. Hasil penelitian menunjukan bahwa sampel segar makroalga jenis Gracilaria sp., yang berada di bagian tengah Pantai Jungwok paling banyak mengandung senyawa bioaktif seperti alkaloid, terpenoid dan flavonoid. The objective of this research was to identify the content of phytochemical in various types of macroalgae at Jungwok Beach, Gunungkidul District, Yogyakarta. This research was conducted at Jungwok Beach, Gunungkidul District, Yogyakarta. The material of this research were macroalgae (Ulva sp., Gracillaria sp., and Boergesenia sp.). This method of research used survey with a qualitative approach. The technique of collecting data was done through purposive sampling. The macroalgae samples were collected from the eastern, central and western part of Jungwok Beach. The phytochemical tests were carried out using qualitative test. Alkaloid screening analysis using the Culvenor Fitzgerald method, while for steroids and terpenoids using the Liberman Buchard Test method, the formed water fraction is followed by flavonoid, phenolic and safonin tests. The results showed that fresh sample of the macroalgae type Gracilaria sp., which is located in the middle of Jungwok Beach, contains the most bioactive compounds such as alkaloids, terpenoids and flavonoids.

PERANAN EKOLOGIS SHIPWRECK ATAU EXPOSED SHIPWRECK SEBAGAI MEDIA HIDUP KARANG DI PULAU BAWEAN DALAM UPAYA PERLINDUNGAN, PENGEMBANGAN DAN PEMANFAATAN SHIPWRECK ATAU EXPOSED SHIPWRECK Heny Budi Setyorini; Hery Priswanto; Ahmad Surya Ramadhan

Metal salvage and theft activities have eliminated most shipwrecks at Nusa Island, and exposed shipwrecks in Gosong Gili, Bawean Island. In order to give recommendations for its conservation efforts, this study aims to identify the remaining shipwrecks or exposed shipwrecks at Nusa Island and Gosong Gili, and the types of corals and fishes in it. This study aims to prove that shipwrecks or exposed shipwrecks is not only having historical and economical value, but also ecological value for the survival of coral reef ecosystem. This is a descriptive-explorative research, data were gathered by underwater survey using GPS Map Sounder, and SCUBA diving. Shipwrecks at Nusa Island is only 30% left in fragmented form of mast, machine, boiler, propeller, ivory vessel, and bricks in the bow area. While the exposed shipwrecks at Gosong Gili is only 20% left in fragmented form boilers, machine, and ivory vessel that might be a cultural heritage according to the UU RI Number 11 of 2010 on Cultural Heritage. At Nusa Island, the corals are consisted of Poritidae and Acroporidae families, and various species reef fishes. While at Gosong Gili, there are more coral families including Merulinidae, Poritidae and Acroporidae, but their reef fishes species are fewer than Nusa island.
