Abstract

Mangrove oyster G. erosa undergo a process of growth and development. The process of growth occuring in this oyster of which is the length, width and weight. The process occurs since the ongoing growth process of conception until adulthood. The aim study is to determine (1) growth coefficient G. erosa, and (2) the length of infinity that can be achieved by the mangrove clam G. erosa in the area of the West Coast of Aceh Besar district. The study was divided into three locations, and observation was conducted in June-August 2009. In each set of four plots in each sample sampling size 10m x 10m and in each plot established 10 subplots each measuring 50cm x 50cm. All samples sampling subplots were damaged and done filtering to obtain G. erosa. The main result was the growth coefficient of mangrove oysters G. erosa in the western coastal area of Aceh Besar district was 0,230 mm, and length of infinity that can be achieved was 84.58 mm. Mangrove oyster G. erosa living in the mangrove ecosystem of the West Coast region of West Aceh Besar district, may reach a length of up to 84.58 mm.

Abstract

The zone of hatching anf nursery of Gelonia erosa in brackish area of Leupung is unknown. Therefore, the study of the zones of both activities, hatching and nursery, must be done.  The study was aimed to determine the zonation of hatching of Gelonia erosa, indicators for hatching and nursery zones, and strategies of management of both zones in the brakhish area Leupung. Data was collected in three locations; Location I (River Leupung), Location II ( River Reuleng), and Location III (River Lhok Kulam). The methods of collecting data were Jarnis Larva Collector used for larva collection, in-situ used to collect biophysic data, and sweep area and destructive methods used to collect the young and mother of the species. It was found that in downstream of Location I, dominated by Nypa fructicans, there were 24 larvas, 10 and 61 individuals of young and mother of Geloina erosa respectivelly. Location II dominated by Nypa fructicans  and Fimbristilys sp had 10, 14, and 49 individuals of larva, young, and adult of Geloina erosa whereas Location III dominated by fructicans  and Fimbristilys sp as well had 12 and 65 individuals of young and adult of Geloina erosa. It can be concluded that the zone of hatching can be determined by the presence of larva, young and adult of Geloina erosa with fully-grown of gonad while the determination of nursery zone is relied on the presence of young and male and female adults of Geloina erosa with well-matured gonads.

Abstract

This study aims to determine the pattern of distribution of Acanthopleura gemmata and the characteristics of the habitat of Acanthopleura gemmata, in Lhoknga Coastal Waters, Aceh Besar District. The research method is observation. The research area was divided into 4 locations namely I Cemara Beach, location II Pasi Jalang Beach, location III Simet Beach and location IV Ujong Lhoknga Beach, Aceh Besar District. Sampling was carried out along the Litoral Zone. Parameters in this study are biological parameters and physico-chemical parameters. Data analysis used the Morishita Index and Principal Component Analysis (PCA). The physico-chemical environmental factors at Lhoknga Beach are water temperature (28C-38C), sediment temperature (28C-38C) pH (6.81-6.95?7), and salinity (25o/oo-26o/oo). The results showed that the Simet Beach Morishita Index was 1.05 ?1, Ujung Beach was 1.01 ?1, while Cemara Beach and Pasi Jalang Beach did not have Acanthopleura gemmata. Habitat characteristics of Acanthopleura gemmata are found in coral rocks, moss and sand substrates. The conclusion of this study is the distribution pattern of Acanthopleura gemmata in the littoral zone of Lhoknga Beach which is random, the habitat characteristics of Acanthopleura gemmata are coral reefs, moss and sand sediments, while the distribution pattern has a positive relationship with the physical-chemical environmental factors of Acanthopleura gemmata which includes pH, except for salinity, water temperature and sediment temperature.Key words: distribution patterns, habitat characteristics, Lhoknga Beach

Abstract

Their self-efficacy or self-confidence, is related to active involvement in solving problems. This belief encourages students to be actively involved in learning and overcoming academic challenges. The solution offered is the application of the Problem Based Learning (PBL) learning model assisted by interactive website-based media. This interactive model and media allow students to be actively involved in learning, to improve their problem-solving skills and strengthen their self-efficacy. The purpose of this study was to analyze the application of the Problem Based Learning (PBL) model assisted by interactive media on improving problem-solving skills and self-efficacy of students. This research method uses a quantitative R&D approach. The population in this study was 143 students, with a sample of 72 students in class XI of SMAN 4 Banda Aceh. Data collection in this study used several techniques, namely the test technique (Problem Solving Skills essay questions) and non-test techniques (Self-Efficacy questionnaire). Based on the research results, it is known that there is an influence of the application of the PBL model assisted by interactive media on improving students' problem-solving skills on the reproductive system material at SMAN 4 Banda Aceh and there is a positive relationship between self-efficacy and students' problem-solving skills through the application of the PBL model assisted by media on the reproductive system material at SMAN 4 Banda Aceh.
