Abstract

This study used a qualitative approach and type of classroom action research. The formulation of the problem of this research is whether the application of the Community Science Science approach to the water cycle material can improve the learning outcomes of the students of Grade 6A SD Negeri 10 Manurunge? And how is the process of applying the Community Technology Science approach to the water cycle material in improving students' learning outcomes in Grade 6A SD Negeri 10 Manurunge? The purpose of this research is to improve student learning result of Grade 6A SD Negeri 10 Manurunge on water cycle material through application of Science Community Technology approach, as well as to improve the process / activity of learning water cycle material through application of Science Community Technology approach 6A SD Negeri 10 Manurunge. The object of this research is the students of Grade 6A SD Negeri 10 Manurunge. Efforts made to improve students' understanding of the concept of water cycle is to carry out learning at the core stage through four phases: the invitation phase, the exploration phase, the solution phase and the application phase. Data collection techniques used were teacher and student observation, and documentation. Based on the results of analysis and evaluation at the reflection stage, the results showed that, the application of Science Community Technology approaches effectively improve the process / activity and learning outcomes in the Water Recycle material in every cycle of action.

Abstract

The study of shoreline changes during 1990 - 2008 in the delta of the River Jeneberang, Makassar was conducted by evaluating sediment transport into and out of a cell. Longshore sediment transport was computed by considering the influence of heights and angles of the breaking waves. Results of calculation of sediment transport showed that the dominant of sediment transport was to the north during the arrival of the southwest and west waves, and to the south when the wave coming from the northwest. Comparison between shore profiles resulting from model and coastline satellite imagery showed similarity. The difference between the two tend to be occurred at the head land part of the shoreline. This was due to complexity of coastal dynamic at the area. The results of the 19 years shoreline simulation showed that there was a tendency of abrasion at the upsteam head land part as the wave energy tend to converge and accretion at the bay part as the wave energy tend to diverge. Abrasion mainly occurred at Tanjung Bunga (head land) where the coast retreat 181.1 m. Accretion occur in the bay area (Tanjung Merdeka) where the coast advance to the sea for about 59.8 m. The shoreline tend to be stable when the profile was straight such as Barombong Coast.Keywords: abrasion, accretion, sediment transport, shoreline changes.

Abstract

Abstrak - Penelitian tindakan kelas ini bertujuan untuk meningkatkan hasil belajar fisika siswa kelas XI SMA Negeri 8 Palu. Masalah yang diteliti adalah rendahnya hasil belajar siswa pada mata pelajaran Fisika. Alternatif pemecahan masalah adalah menerapkan pendekatan pembelajaran SAVI. Subyek penelitian adalah siswa kelas XI SMA Negeri 8 Palu, dengan jumlah siswa 20 orang. Penelitian ini menggunakan Penelitian Tindakan Kelas yang dilaksanakan secara bersiklus dan mengacu pada desain penelitian dari model Kemmis & Mc. Taggart, yang meliputi 4 tahap: (i) perencanaan (ii) pelaksanaan tindakan (iii) observasi (iv) refleksi. Jenis data yang diperoleh adalah data kualitatif dan data kuantitatif. Data kualitatif adalah data yang diperoleh dalam kegiatan belajar mengajar berupa observasi dan wawancara. Hasil observasi aktivitas siswa dan guru pada siklus I yaitu cukup dan baik, sedangkan siklus II berada pada kategori baik dan sangat baik. Sedangkan data kuantitatif adalah data hasil belajar yang diperoleh dengan tes. Hasil belajar siklus I diperoleh ketuntasan belajar klasikal yakni 65% dengan jumlah yang tuntas sebanyak 12 orang siswa dan yang belum tuntas 7 orang siswa. Pada siklus II ketuntasan belajar klasikal sebanyak 85 % dengan rincian 17 orang siswa tuntas dan 3 orang siswa yang masih belum tuntas. Berdasarkan hasil tersebut dapat disimpulkan bahwa dengan penerapan pendekatan pembelajaran SAVI dapat meningkatkan hasil belajar siswa. Kata Kunci     : Pendekatan SAVI, Hasil Belajar Fisika

Abstract

The vulnerability of Makassar coast was measured using parameters of Coastal Vulnerability Index (CVI). CVIvalue was determined using geomorphology, shoreline change, coastal slope, mean wave height, mean tidalrange, and relative sea level change parameters. The Makassar coast was divided into a numbers of cells, eachwith the length of 1 km and width of 0.5 kminto the sea. CVI values werecalculated for each cell and the coastalvulnerability wereclassifiedinto five categories: very low - low - medium - high - very high. The results show thatthe coastline with high to very high vulnerability index are located at the southern part of Makassar, while thenorthern coastline generally have low to moderate vulnerability. The CVI parameters which contributed to highsusceptibilitywere the coastal slope and the shoreline change parameters. Keywords: Coastal Vulnerability Index, coastal slope and shoreline change, Makassar.

Abstract

Some upper air atmospheric parameters measured during period of 2011-2016 by means of radiosonde located at Hasanuddin International Airport were examined for characterization of boundary layer over Makassar, Indonesia. These data, combined with surface atmospheric parameters were used to calculate some boundary layer parameters using AERMET model which based on Monin-Obukhov similarity theory. The obtained Monin-Obukhov length which reflecting atmospheric stability then converted into traditional Pasquill-Gifford stability classification. Examination of wind characteristics of wind showing clearly their dependence of the day, season and height. Winds dominantly flows from the southeast during the daytime with the relatively larger velocity and from the northwest with smaller velocity during the nighttime. Interpretation of monin-obukhov length using Pasquill-Gifford stability classification showing that the atmosphere was dominantly unstable during the daytime and dominantly stable during the nighttime. These atmospheric stabilities were also varied during seasons. The height of convective boundary layer (CBL) was start to rise in the morning and reaching its maximum in the afternoon (18:00) at the mean value of 2 km. Meanwhile, the height of mechanical boundary layer (MBL) during the day time forming parabolic curve with its maximum value of 1.2 km at noon. These indicated that any released pollution from the stack will be less dispersed during the nighttime due to the fact of lower mixing height, lower wind speed, atmosphere become more stable, and it dispersed in different direction compare to the daytime.
