Abstract

Dengue haemorrhagie fever is one of the disease which caused by dengue virus. It spreads out by mosquito Aedes aegypti as the vector. To date, people use abate as the larvacidal.  Yet it causes the negative effects, such as bad odor, rustiness of the water container and resistency either to the larvae or to the living environment if continue using it. The objective of the research was to examine the larvacidal activity of Didemnum molle extract against A. aegypti larvae. The sample was extracted with methanol to give methanolic extract which was further partitioned with ethyl acetate, hexane, and chloroform to yield three fractions of ethyl acetate, hexane, and chloroform. Methanolic extract and the three fractions were tested against the A. aegypti larvae instar III for several concentrations. Abate and tap water were used as controls. The result exhibited that Didemnum molle extracts contain or produce larvacidae substances against A. aegypti larvae. They are approved by the data of methanolic extract and the 3 fractions which are more powerful than abate, particularly hexane. However it still needs to be purified to obtain single active compound.

Abstract

One of potential fishing grounds for small pelagic fish in Southeast Mallucas Regency is Rosenberg Strait waters. In this region, a study on the effect of different light intensities of floating lift net on fish catches was carried out. The analyses were done on light distribution of 4 light intensities different: Petromaks Lamp and Underwater Lamps of each 18 watt, 36 watt and 54 watt. This study showed that catches of floating lift net using different light intensities were statistically significantly different. The use of 36 watt and 54 watt underwater lamp yielded the same amount of catches but higher than that of 18 watt-underwater lamp and petromaks, both in number and species. Catches consisted of 17 species, 16 fishs and 1 mollusca. Number of species and size also varied with light intensity used. There were 13 fishs species dominated by Stolephorus indicus as much as 46.9 kg or 22% for petromaks catches, 14 fishs species dominated by Rastrelliger kanagurata as much as 64 kg (31%) for 18 watt underwater lamp, 17 fishs species dominated by Rastrelliger kanagurata as much as 76 kg (28%) for 36 watt underwater lamp, and 15 fishs species dominated by Stolephorus devisi as much as 54.8 kg (22%) for 54 watt underwater lamp, respectively. Based on the results, it is recommended that the use of light intensity in fishing operations of floating lift net should be 36 watt and 54 watt underwater lamps, due to high catches, both in number and species. Beside that, since light fishing has also caught illegal fish size, number of this fishing gear type should be controlled.

Abstract

ABSTRACTBentenan village, located on the East coast of Minahasa peninsula and surrounded by gently sloping hills, has a shoreline of 1.3 km. The shape of the shoreline is curved facing Bentenan Island. It is observed that coastline had been gradually retreating. Research and data collection on the coastline has been conducted in November 2008. As many as 85 points have been plotted using GPS, rectified with LPI maps and compared with a couple of old maps, i.e., Peta Dishidros Lembar 334 1992 and Peta Laut No. 62 1985. Shoreline of Bentenan village shown to be retreated 165 meters in average towards the mainland from 1985 to 2008 (23 years), averaging a decrease of 7.17 meters. This indicates that the shore of Bentenan undergoes a process of erosion/ abrasion which causes changes in shoreline backwards towards the land, also called beach retreat.Keywords: Bentenan, shorelines, Abrasion, beach retreat, geomorphology.ABSTRAKDesa Bentenan memiliki panjang garis pantai sekitar 1,3 km, terletak di pantai Timur semenanjung Minahasa yang bertopografi landai dan dikelilingi oleh perbukitan. Bentuk pantainya melekuk ke dalam dan di bagian depannya terdapat pulau Bentenan. Teramati bahwa bentuk pantai ini makin mundur dari tahun ke tahun. Observasi dan pengukuran dilakukan pada bulan November 2008, sebanyak 85 titik telah dipetakan dengan menggunakan GPS dengan koreksi dari peta LPI dan hasilnya dibandingkan dengan beberapa peta terdahulu yaitu Peta Dishidros lembar 334 tahun 1992, Peta Laut No 62 tahun 1985. Perbandingannya menunjukan garis pantai desa Bentenan mengalami perubahan rata-rata sebesar 165 m mundur ke arah daratan dalam selang waktu 1985-2008 (23 tahun). Dalam periode tersebut setiap tahun daerah ini meng-alami kemunduran garis pantai rata-rata 7,17 m.Kata kunci: Bentenan, Garis pantai, Abrasi, Pantai mundur, geomorfologi.
