Abstract

DOI:10.17014/ijog.8.2.147-156Indonesia is an archipelago blessed with the wealth of coastal resources, but also with the risk of natural hazards including tectonic earthquake and tsunami. This potential risk is high in the Purwodadi Subregency, Purworejo Regency, Indonesia, because of its location in an active subduction zone at the edge of the Indian Ocean. Therefore, this study was conducted in the region located on the southern coast of Java Island. The high probability of disaster in the area needs a proper coastal management strategy and mitigation measures. Hence, this study aims to establish an appropriate policy using the strength-weakness-opportunity-threat (SWOT) analysis. Furthermore, the data obtained from this novel analysis include the population and social vulnerability, geological conditions, landuse allocation, and disaster strategies. Each is carefully assessed and then incorporated into the matrix to obtain the result. In addition, the alternative strategies used are the development of disaster mitigation facilities, infrastructure, and institutional strengthening.

Abstract

Brebes Regency is an endemic area of Lymphatic Filariasis (LF) and has the highest number of LF cases in Central Java Province, Indonesia. Despite it is located in the coastal region, which is already known as one of the risk factors of LF, the LF case is distributed more in rural areas, away from the shoreline. Adult mosquitoes need a particular site, called a resting place, to rest after and before biting for a blood meal. The purpose of this study was to analyze spatially the distribution of LF cases and mosquito resting places in three subdistricts whose highest LF case is in the Brebes Regency. The three subdistricts are rural areas. The observed resting places were cattle pens, unmaintained bushes, and maintained bushes. The data of LF patients were obtained from the Health Office of Brebes Regency, which stood at 14 patients. Spatial mapping of LF case and mosquito resting place distribution was composed. 4 patients were located in the mosquito flight radius from unmaintained bushes, 3 patients were located in the mosquito flight radius from cattle pen, and 7 patients were located in the mosquito flight radius from both unmaintained bushes and cattle pen. It indicated unmaintained bushes, together with cattle pen, are the favorable resting place contributing to LF transmission.

Abstract

Purworejo Regency is located in the south coast of Java where rivers flow into the Indian Ocean. The Jali River in Purworejo becomes a migration route for eels where juvenile eels (glass eels) move from the ocean to freshwater passing through the estuary. During migration, glass eels will make efforts to survive, one of which is to manage their osmotic pressure (osmolarity). With regards to those, a study on the upstream migration of glass eels in Jali River was carried out. Glass eels samplings were conducted using hand-held lift nets at the new moon phase, from 20:00 pm to 4:00 am. Sampling stations included the estuary, a branch river, and below the dam. The osmolarity of both glass eels and media (river water) were measured. Furthermore, the chemical and physical parameters of the waters as the natural habitat for glass eels were also measured. Glass eel samples were then identified to species level. The results showed that glass eels entering the Jali River consisted of Anguilla bicolor bicolor and Anguilla nebulosa nebulosa with the former being the most common. Total length of glass eels ranged between 44.10 to 69.70 mm with total weights 0.08 to 0.54 g. Glass eel migration has a close relation with surface current and tide. The osmotic work level (OWL) of glass eels approaches 0.34 mOsm/l H2O which is close to iso-osmotic. This happened at salinity 0 o/oo so that the glass eels migrate to fresh water which has a lower salinity to achieve iso-osmotic condition.

Abstract

ABSTRACT Grouper Epinephelus sp. farming activities in Lampung Bay is limited to an area of 77 hectares, while areas that are potential to be used for grouper farming are still very wide. Therefore, this study aimed to assess the suitability of Lampung Bay waters for grouper farming activities. The study was conducted in 20 stations with ecological preference considerations. The parameters observed were physicochemical (water depth, temperature, water transparency, the load of suspended solids, pH, dissolved oxygen, salinity, nitrate, and phosphate) and biological parameters (phytoplankton abundance and chlorophyll-a concentration). After the data were completely obtained, the data were processed into suitability matrix resulting in scores that will be grouped into four classes, namely S1 (highly suitable), S2 (moderately suitable), S3 (marginally suitable), N (not suitable). The geostatistical model was used to perform the earth’s surface mapping based on biotic and abiotic parameters that were analyzed. Based on the results of the analysis in this study, the conditions of Lampung Bay waters were suitable for grouper farming activities. Marine area that could be used for grouper farming was 33,847.12 hectares (S1: 15,712.6 ha, S2: 13,294.7 ha and S3: 4,209.82 ha) in the area around Puhawang Island, Kelagian Island, Maitem Island, Tegal Island to Hurun Bay. Keywords: Lampung Bay, grouper, suitability analysis, fish farming   ABSTRAK Kegiatan budidaya ikan kerapu Epinephelus sp. di Teluk Lampung masih terbatas pada lahan seluas 77 hektar, sedangkan lahan yang berpotensi digunakan untuk budidaya ikan kerapu masih sangat luas. Oleh karena itu, penelitian ini bertujuan mengkaji kesesuaian perairan Teluk Lampung untuk kegiatan budidaya ikan kerapu. Penelitian dilakukan di 20 stasiun dengan pertimbangan ecological preference. Parameter yang diamati yaitu parameter fisika-kimia perairan (kedalaman, suhu, kecerahan, muatan padatan tersuspensi, pH, oksigen terlarut,  salinitas, nitrat, dan fosfat) serta parameter biologi (kelimpahan fitoplankton dan konsentrasi klorofil-a). Setelah data parameter terpenuhi, data diolah ke dalam matriks kesesuaian sehingga menghasilkan skor yang akan dikelompokkan ke dalam empat kelas, yaitu S1 (highly suitable), S2 (moderately suitable), S3 (marginally suitable), N (not suitable). Model geostatistik digunakan untuk melakukan pemetaan permukaan bumi berdasarkan data parameter biotik dan abiotik yang dianalisis. Berdasarkan hasil analisis pada penelitian ini, kondisi perairan Teluk Lampung sesuai untuk kegiatan budidaya ikan kerapu. Luas perairan laut yang dapat digunakan untuk kegiatan budidya ikan kerapu yaitu, 33.847,12 hektar (S1: 15.712,6 ha, S2: 13.294,7 ha dan S3: 4.209,82 ha) di daerah sekitar Pulau Puhawang, Pulau Kelagian, Pulau Maitem, Pulau Tegal hingga Teluk Hurun.   Kata kunci: Teluk Lampung, ikan kerapu, analisis kesesuaian, budidaya

Abstract

This study aims to analyze the relationship between salinity and the extent and type of mangrove vegetation in ponds within the Mahakam Delta, East Kalimantan. Sampling was conducted in ponds with different salinity levels: 0–10 ppt, 11–20 ppt, and 21–30 ppt, with each salinity category represented by 10 pond plots. Data analysis was performed using linear regression. The results showed a strong relationship between salinity variation and pond area, with an r-value of 0.630. The extent of pond expansion is related to the original mangrove type present in the pond area. This information can be used as a basis for determining suitable aquatic species for cultivation based on salinity levels. In other words, the selection of aquatic species for cultivation can be adjusted according to the appropriate pond area. Further research is needed to determine whether other factors influence the relationship between salinity levels and pond area in the Mahakam Delta region.

Abstract

The role of the river as a site for riverine activities has a huge impact on the economic sustainability of the community and the riverine ecosystem. The Silugonggo River is the only river in Pati Regency that is a very densely populated shipping route. This research was conducted along the Silugonggo River from the Juwana Bridge to the estuary. The purpose of this study was to determine ship activity in the Silugonggo River, determine the feasibility of facilities at Juwana Port and analyze environmental conditions along the Silugonggo River. The method used is a qualitative method with observation techniques and laboratory analysis, which is carried out by observing and recording conditions in the field systematically using primary data in the form of water conditions and secondary data in the form of ship activity and construction data. The results showed that the activities in the port of Juwana include mooring, loading and unloading of goods, ship repair and refuelling of ships. The level of water pollution in the Silugonggo River at 5 sampling points shows that the oil content in the water for points 1, 3, 4 and 5 is still considered safe because it is below the quality standard, but the oil content at point 2 has a very high value from the set quality standard which is 20 mg/L. The pollution that occurs is caused by shipping activities that dump waste into the water and fuel filling activities.Keywords:marine polutionportriverwater qualityoil spill
