Alteration in magmatic-hydrothermal systems leads to distinct changes in rock texture and mineralogy, and a strong redistribution of elements between fluid and rock. Here, we experimentally interacted andesite scoria with hyperacidic, high-sulfidation style fluids from Kawah Ijen volcano (Indonesia) at 25 and 100 °C, seeking to reproduce the textures observed in natural samples from this volcano, and to understand the element fluxes that accompany alteration. The susceptibility to alteration in the experiments is Cu–Fe-sulphide > calcic plagioclase > pyroxene > titano-magnetite > sodic plagioclase, with complete preservation of glass. Silicate minerals alter to opaline silica, and gypsum, barite and a Zr-phase precipitate. The selective alteration of the phenocryst minerals results in a preferential release of compatible elements, as the glass is the main incompatible element host. The experiments reproduce the alteration textures of the natural samples, including the preservation of glass, but the predicted compatible over incompatible element enrichment in the alteration element flux is not observed in the natural setting. This suggests that alteration at Kawah Ijen is dominated by lithologies that lack abundant glass, in particular lava flows where the glass has devitrified, despite these lava flows having a lower surface area compared to scoria.

Taman Wisata Alam Kawah Ijen (TWAKI) merupakan salah satu obyek wisata di Jawa Timur yang sudah sangat terkenal akan keindahan alamnya dan semakin tahun jumlah wisatawan semakin meningkat. Namun, pengelolaan kawasan konservasi di TWAKI saat ini belum optimal dalam pengembangan ekowisatanya. Pengelolaan kawasan TWAKI menghadapi berbagai macam tantangan, dari faktor eksternal seperti vandalisme, kebakaran hutan, TWAKI menjadi mass tourism, gempa freatik dan keluarnya gas beracun, serta dari faktor internal, seperti: sumber daya, anggaran, tata batas, dan manajemen. Terkait permasalahan dan upaya pengelolaan yang telah dilakukan oleh Balai Besar Konservasi Sumber Daya Alam (BBKSDA) Jawa Timur, maka perlu dilakukan penilaian efektivitas pengelolaan kawasan konservasi di TWAKI. Tujuan penelitian ini adalah mengkaji efektivitas pengelolaan kawasan konservasi pada setiap siklus pengelolaan yaitu perencanaan, masukan, proses dan keluaran sehingga didapat rekomendasi strategis yang efektif untuk peningkatan efektivitas pengelolaan kawasan konservasi dalam pengembangan ekowisata di TWAKI. Berdasarkan hasil penilaian Management Effectiveness Tracking Tool (METT) kawasan TWAKI, didapat nilai skor METT telah mencapai nilai minimum indeks METT yang artinya kawasan konservasi sudah dikelola secara efektif. Salah satu strategi untuk mendorong pengelolaan TWAKI yang berkelanjutan, efektif dan berdampak bagi kesejahteraan masyarakat yaitu pengelolaan secara bersama dengan pemangku kepentingan (stakeholders) untuk membangun suatu model kolaborasi pengelolaan.

This research has an aim to examine the role of Sport Tourism through the program of Banyuwangi festival (B-Fest) and the impact of local content and deciding sustainable strategy of Sport Tourism Development. This research uses descriptive associative research method with qualitative and quantitative approach. Data Collection method done by observation, direct interview, questionnaire and collect the data from related instance. The result of this analysis shows that: (1) Banyuwangi Festival Program (B-fest) successfully increase the number of visitor in Kawah Ijen and Pulau Merah within total contribution of 75.9%; (2) The effect of sport tourism toward the change of local community in Kawah Ijen, on economic aspect contribute 100%. On social aspect contribute 11.6%. Environmental aspect, edelweiss flower no longer to be seen, Javan lutung and deer are rarely to be seen. Social Aspect contribute 2.6% toward people prosperity, 0.2% toward local satisfaction, 12.7% toward people participation; (3) Development strategy on sustainable sport tourism using the model of Sport tourism Participation and oriented to tourism characteristic.
