Abstract

Telah dilakukan studi mengenai karakteristik dan distribusi salinitas dan temperatur dan water system di estuaria Merbok dan di sekitar perairan pantai. Penelitan ini difokuskan pada proses-proses fisika. Hasil analisis menunjukkan suatu pola variabilitas khusus mengenai fenomena yang terjadi secara horizontal. Pada kondisi debit air (discharge) yang tinggi, air dengan salinitas (isohalines) rendah akan terdapat di dekat mulut sungai. Pada kondisi debit air rendah, keberadaan air sungai mengisi lebih jelas di estuaria bagian bawah. Pola yang sama juga teramatiuntuk parameter temperatur di daerah yang sama yang disebabkan rendahnya debit sungai. Dengan debit yang lebih tinggi dapat menyebabkan perubahan temperatur air payau dibandingkan debit yang lebih rendah. Hal ini menyebabkan terjadi proses transisi stratifikasi antara debit air yang tinggi dan rendah tersebut.Kata kunci: debit sungai (discharge), salinitas, temperatur, perairan pantai, estuaria. The characteristics and distribution of the salinity and temperature and water systems in the Merbok Estuary and nearby coastal waters are examined. This research focuses mainly on physical processes. The results analysis provides an insight the typical scales of variability of the horizontal phenomena. During high discharges, the lower salinity water (isohalines) was more evident near the estuary mouth due to high discharge. During low discharge, the invasion of freshwater in the lower estuary was much less pronounced. Similar temperature trend was observed for the estuary possibly due to low discharge phenomenon. Bigger amount of freshwater can dictate the brackish water temperature compare to smaller amount of freshwater. There was a transition in stratification between high and low river discharge.  Key words : river discharge; salinity; temperature; coastal water; estuary

Abstract

Abstrak: Penelitian ini dilatarbelakangi oleh adanya keraguan terhadap kinerja mengajar guru sekolah dasar di Kecamatan Pontianak Selatan. Keraguan tersebut berawal dari mutu lulusan yang tidak naik secara signifikan dilihat dari nilai UASBN. Mutu lulusan seperti itu dituding banyak pihak, selain guru sebagai faktor penyebabnya adalah kepala sekolah yang tidak mampu membuat para guru mengajar dengan berkualitas. Meskipun diyakini banyak faktor yang mempengaruhi kinerja seseorang, namun dalam kajian ini atasi pada supervisi akademik dan kepemimpinan kepala sekolah. Secara teoretis makin baik supervisi akademik kepemimpinan yang dilakukan kepala sekolah, maka akan makin baik kinerja mengajar guru. Hasil penelitian menunjukkan bahwa supervisi akademik dan kepemimpinan kepala sekolah secara bersama-sama berpengaruh secara signifikan terhadap kinerja mengajar guru. Kontribusi kedua variable tersebut adalah 30,1%. Dengan demikian, 69,9% dari varians kinerja mengajar guru dijelaskan oleh variabel lain yang tidak diteliti. Selain itu, hasil penelitian menunjukkan bahwa secara sendiri supervisi akademik berpengaruh signifikan terhadap kinerja kepala sekolah dasar. Begitu juga dengan kepemimpinan kepala sekolah. Kedua variable tersebut masing-masing menjelaskan 15,68% dan 6,96% variasi kinerja mengajar guru sekolah dasar negeri Pontianak Selatan. Kata Kunci: supervisi akademik, kepemimpinan, kinerja mengajar. Abstract: The background of this reaseach was teaching performance of teacher at state elementary school (SDS Negeri) are questioned. The fact showed that quality of output is not increase significantly based on national final examination. Some people argued that it is not only teacher falseness, but also headsmaster who can not do something so that teacher can teach with high quality. Some factors give effect on teaching performance, but in this research academic supervisition and leadership of headmaster hypothesized more effect on teaching performance.The research result showed that academic supervision and leadership of headmaster affected on teaching performance simultaniously. Contribution of both variables were 30,1%. It also means that almost 69,9% ofb variance of teaching performance can not be explained by both variables. This research study also showed that each variable give effect on teaching performance significantly. Each variables explained 15,68% and 6,96% of variance of teaching performance at elementary school teacher in South Pontianak. Key words: academic supervisition, leadership, teaching performance

Abstract

Seulawah Agam is an active volcano with high 1,810 m located at 5.448°N 95.658°E and close to the capital of Aceh province densely populated. Following Sumatra-Andaman earthquake 26 December 2004, Sumatra Island has increased not only seismicity but also volcanic activity. On the other hand, Sinabung volcano categorized as inactive volcano, but beyond expectations on the 3rd September 2010 experienced eruption and the closest volcanic eruption location to Seulawah Agam volcano. Meanwhile, in 1 September 2010, Seulawah Agam categorized as active volcano was alert to level 2. We cannot predict what happens in future to the Seulawah Agam volcano, but we can provide volcano hazard assessment as important step for mitigation procedure. This paper introduces numerical study for volcanic eruption and integrated with a GIS-based tool for volcanic hazard assessment VORIS (VOlcanic Risk Information System) which develop by Alicia Felpeto.  This model investigate scenario based volcanic eruption for ash fallout, PDC (pyroclastic density currents), and lava. Digital elevation model (DEM) from SRTM (Shuttle Radar Topography Mission), meteorological data from NOAA, and geological study are used in this model. In the statovolcano mountain four geothermal manifestations appeared, such as: Fumarol Simpago, crater Heutz, ground steam Ie-Jue, and hot spring Ie-Suum. In this numerical simulation, we consider the location as potential eruption vent to produce erupted material. Wind velocity data at 3rd January 2012 and 1 July 2012 above the summit is selected to represent wet and dry season condition for scenario based ash fallout. Further, the simulation show the ash fallout is possible to reach Banda Aceh and potentially disrupt flight at Sultan Iskandar Muda Air port. Lava flow simulations are only depending on topography data (DEM) and applying some parameter for maximum flow length 5 km. The Simulation resolution depend on DEM data (90m) which produce more precise then volcanic hazard map produce by Center of Volcanology and Geological Hazard Mitigation, Bandung (CVGHM) and more reasonable with topography slope of mountain at southern part and northern part. Furthermore, PDC simulations are conducted scenario for height eruption column (starting point of the flow) 20m dan 200m. The simulations show PDC can be reach longer location until Banda-Aceh Medan Highway compare then CVGHM map.  This preliminary research should be developed to apply high resolution DEM and using adequate method for estimation eruption parameters. This method will be potential to provide more precise volcano hazard assessment for others volcano in Indonesia

Abstract

The paper presents a case study of liquefaction investigation, carried out in an area of the South Aceh coast. The zone lies on low flat plain at Tanjung Harapan Village, west coast of Aceh. The process of site investigation is controlled by: occurrence of groundwater, nature of bedrock, and presence of clays. Prediction of liquefaction zones in high seismicity regions will be a great help to mitigate hazards. Geoelectric resistivity using a combination both vertical electrical sounding and horizontal resistivity images of Wenner-Schlumberger configuration have been carried out and can be of help to delineate the liquefaction zones. With this backdrop, it believe that in conjunction with soil and sediment characteristics indicating high susceptibility to liquefaction, and resistivity anomalies will provide vital information to predict and identify the liquefaction zones. Results of this study revealed the surface layer consists of loose sediments, sandy clay, and silty sandy layer are potentially liquefied during earthquake. The 2-D model sections at 10 m electrode spacing were described, together with subsurface structures can be used to predict the resistivity values at a approximately 48 m depth

Abstract

AbstrakSumatera Barat merupakan provinsi dengan prevalensi penyakit jantung tertinggi ke-4 di Indonesia. Prevalensi penyakit ini meningkat disebabkan karena faktor risiko yang dapat dimodifikasi yaitu dislipidemia, hipertensi, diabetes melitus, merokok, dan obesitas. Faktor risiko tersebut terkait dengan peningkatan kejadian PJK. Tujuan penelitian ini adalah untuk mengetahui hubungan faktor risiko yang dapat dimodifikasi dengan kejadian PJK. Penelitian ini merupakan penelitian analitik dengan desain potong lintang yang dilakukan di RS Dr. M. Djamil Padang dari Desember 2012 sampai Mei 2013. Populasi penelitian ini adalah seluruh pasien PJK yang dirawat inap dan telah dilakukan angiografi pada Januari 2012 sampai Desember 2012 dengan 68 orang sebagai subjek penelitian. Data pasien didapatkan dari rekam medik. Data dideskripsikan dengan tabel dan dianalisis dengan uji chi-square. Hasil penelitian menunjukkan distribusi frekuensi terbanyak pasien PJK terdapat pada kadar kolesterol HDL rendah (64,6%) dan hipertensi (72,5%), namun hasil uji bivariat tidak menunjukkan hubungan yang bermakna antara kadar kolesterol HDL rendah dan hipertensi terhadap kejadian PJK. Kesimpulan hasil penelitian ini ialah kadar kolesterol HDL rendah dan hipertensi belum tentu menyebabkan PJK.Kata kunci: penyakit jantung koroner, faktor risiko, HDLAbstractWest Sumatra is a province with the highest prevalence of heart disease 4th in Indonesia. The prevalence of this disease increases due to modifiable risk factors, namely dyslipidemia, hypertension, diabetes mellitus, smoking, and obesity. The risk factors associate with an increased incidence of Coronary Heart Disease (CHD). The objective of this study was to determine the relationship of modifiable risk factors with CHD events. This study was a cross-sectional analytic design conducted at Hospital Dr. M. Djamil Padang from December 2012 until May 2013. The population in this study were all hospitalized CHD patients and angiography was performed in January 2012 - December 2012 with 68 patients as a research subject. Obtained from the patients medical record. The data described in tables and analyzed with the chi-squared test. The result showed that the frequency distribution of most CHD patients are at low levels of HDL cholesterol (64.6%) and hypertension (72.5%). Bivariate test results showed no significant association between low HDL cholesterol and hypertension on the incidence of CHD. The conclusion is the low HDL cholesterol levels and hypertension not necessarily lead to CHD.Keywords: coronary heart disease, risk factors, HDL
