Abstract
Because of the ITF system, Makassar Strait (MS) has an important role in the Indian Ocean and Indonesia seas. Tides, current, heat, and freshwater from the Pacific Ocean transferred to that ocean through the MS. By using a two-dimensional numerical model, this paper aims to observe the M2 patterns and their effect on the current circulation. For model validity, we compared the M2 tides with the assimilation data obtained from Geospatial Indonesian Agency (BIG tides). The model of amplitude and phases of Makassar Strait show good results. Amplitude is high in the southern bay of Kalimantan and the northeast of MS. The low amplitude can be seen at the south of MS. The phases are denser in the south of MS than in the center and north of MS. The M2 current circulation always moves to the south of MS during M2 periods (t=T/4, t=T/2, t=3T/4, and t=T). The currents are strong around Sulawesi Island. The results show that M2 has a great contribute to MS circulation and the ITF.

Abstract
The Indian Ocean Tsunami on 26th December 2004, had caused devastation on land and coastal ecosystems. One of the worst affected ecosystems is the mangrove forest. Many areas of mangrove forest have been destroyed, and it may pose a long-term impact for the region, both in terms of forest and biodiversity conservation and in terms of the ability of the ecosystem to support the livelihoods of the coastal communities. The tragedy of tsunami has requested the rationale for conserving and sustainably managing natural ecosystems among the researchers and scientific community. The research was carried out to make a post-tsunami damage assessment and recovery of mangrove forest in Banda Aceh city area. Several high-resolution satellite imageries data have been effectively used to detect, assess and monitor the changes of mangrove forests in the pre and post-tsunami period using multi-temporal optical satellite data. An on-screen visual interpretation was made to identify the heterogeneous patches for the preliminary classification of fieldwork. A supervised classification was performed to obtain the pre and post Tsunami assessment maps. Accuracy assessment of the classified maps was performed on pixel-level using ground truth. The result highlighted the changes in the spatial extent of the mangrove forests in the study area as a result of Tsunami disaster. The latest condition of the mangrove forest recovery is about 90.3% of the total damage area.

Published: November 2019

Abstract
The Scalloped Spiny Lobster (Panulirus homarus) is the most caught species of the genus Panulirus in the coastal waters of Gunungkidul. As a result of the high economic value of this species, its catch rate continues to increase. The management of lobster fishery is less precise when using conventional bioeconomic models due to several things, among others are the distribution of its stock is spread according to spatial distribution, low levels of fish resource mobility and the tendency to be biased if the spatial aspects are not taken into account. Growth, mortality, and recruitment parameters are also highly dependent on environmental conditions albeit within a small distance. A spatial bioeconomic approach was carried out to assess a utilization optimization model, by taking into account the biological, ecological, and economic characteristics of this species' capture. This research was carried out in six lobster landing locations in Gunungkidul District, Yogyakarta, Indonesia. Catchability, fuel price, selling price, total cost, and total revenue from each lobster landing locations were identified to determine the dynamic spatial allocation of fishing effort. We found that the capture of P. homarus in four lobster landing locations (Gesing, Ngerenehan, Siung, and Sadeng) can be optimized during peak catch seasons, while in Gesing and Siung can be optimized during catch drought seasons.
