Judul: Perubahan garis pantai Tanjung Berikat, Pulau Bangka Periode 1992 - 2000
Abstrak: The offshore wave regime of Tanjung Berikat beach, in the West coast of Bangka was presented based on the analysis the availability of a dense set of the ERS (European Remote Sensing) 1/2 wind measurements at particular offshore location. The coastlines was divided into several segments represented by local orientation of the coastline. For each of these segments, the breaker wave height, depth and angle of breaker wave and longshore sediment transport were calculated. A linear regression fitting was made based on the total wave regime, to obtain the relation between the peak period, Tp and wave height, Hmo: To 3,2188Hmo +1,8932 Waves approach from directions 0100-055° N, 0550-100° N, 1000-145° N, 145°-180° N, 2810-325° N and 3250-010° N, but most frequent from 2810-325° Ν. The smallest wave height was 0,06 m from directional sector N100-055° in winter and largest 2,8 m from N145°-180° in summer. Incoming waves from the directional sector N281-325° account for most of the winter wave regime duration, about 52%. Such sector was predominantly associated to waves with mean wave height 0,84 m. Also about 28% of the summer wave regime duration corresponds to incoming waves from the directional sector N281-325°, which is mostly associated to waves with mean wave height 0,63 m. The results obtained in this study allowed to estimate the net drift for the periode 1992-2000, the annual variations of the littoral drift to obtain 25 years return periode and rate of accretion and erosion. For the periode 1992-2000, the shoreline showed an accretion at some segments with maximum rate of 6,15 m/year and an erosion at others with maximum rate of 5,16 m/year. For 25 years return periode, shoreline was predicted to be accreted at some segments with maximum rate of 8,8 m/year and eroded at others with maximum rate of 8,4 m/year.

Judul: Perubahan garis pantai dari pantai Teritip Balikpapan sampai pantai Ambarawang Kutai Kertanegara Kalimantan Timur
Abstrak: Shoreline change from coast of Teritip Balikpapan to coast of Ambarawang Kutai Kertanegara, East Kalimantan from 2000 – 2007 was analyzed by developing a model. Initial shoreline as an input for model was the result of Landsat image in 2000, and the shoreline from Landsat ETM in 2007 was used to compare the final result of model. The model predicts shoreline change due to along shore sediment transport generated by wave that brakes at the shoreline. The characteristics of broken waves was predicted by analysing wave transformation from off-shore sea where the wave was generated by winds. Sediment transport along the coast were mostlynortheastward as the main winds that blown toward the coast were mostly from the south. Simulation for 8 years showes that accretion more intensive in the northern part than those in the south. In general, shoreline shape resulting from model show a good resemblace to those from Landsat image in 2007. Discrepancies between the two shoreline shape occurred mostly at the upstream of the head land where results of model shows erosion but the images show the shoreline almost stable. This is perhap due to existance of mangrove that prevent erosion, but the effect of this vegetation is not included in the model.

Judul: Case Study of Gallbladder Mucocele and Treatment Used In Small Animals
Abstrak: Gallbladder mucocele (GM) is defined as distention of the gallbladder caused by an inappropriate accumulation or deposition of high concentrations of bile. The purpose of this case study is to study GM conditions in small animals and to report the clinical sign and characteristics of GM through the sonogram interpretation and blood chemistry test evaluation, and studies related to the therapy given and other treatments recommended. A 14-year-old Toy Poodle dog has been diagnosed with severe GM and cholecystitis. No pain signs were shown during the physical examination as asymptomatic is a common characteristic in the early stage of biliary related diseases. In this study Abdominal ultrasonography interpretation and blood chemistry evaluation was conducted in 2021-2022 and analyzed as a secondary data source. Ultrasonography results showed presence of hyperechoic, immobile deposits in gallbladder accompanied by wall thickening and enlarged in size, followed by a significant increase in the enzyme alkaline phosphatase (ALP). This study has summarized mainly the diagnosis and treatments of GM in small animals and suitable alternatives treatments were recommended to encounter the GM conditions in small animals. The effectiveness of combined therapy shows the positive impact on the patient, the condition of GM has been under control.
