Published: October 2018

Wilayah pantai Ngungap, kawasan pesisir selatan Wonogiri, Jawa Tengah merupakan daerah jalur anjak dimana terumbu karang Kuarter tersingkap dari garis pantai hingga pebukitan tinggi. Enam undak laut terbentuk sejajar dengan garis pantai hingga mencapai ketinggian lebih dari 300 meter di atas muka laut. Hasil pentarikhan Radiokarbon tiga fosil terumbu karang dari undak laut termuda yang dapat berkontribusi terhadap perhitungan proses pengangkatan kawasan pantai Ngungap. Undak laut termuda menunjukan bahwa rata-rata aktivitas tektonik pengangkatan diwilayah pantai Ngungap, kawasan pesisir selatan Wonogiri adalah 5 mm/tahun. Pengangkatan rata-rata pesisir selatan Wonogiri jauh berbeda dengan kecepatan kawasan pantai-pantai tektonik aktif lainnya di Indonesia. Kata kunci : anjak, terumbu karang, undak laut, pentarikhan, pantai Ngungap Jawa Tengah The Ngungap coast of the southern coastal zone of Wonogiri, Central Jawa, situated in the central portion of the arcuate thrustbelt where Quaternary reefs show maximal elevation from coastline up to high hinterland. Six terraces have been formed parallel to the coast line and extensively exposed up to more than 300 meters above mean sea level. Three Radiocarbon dating of coral reef derived from the lowest terraces can be contributed to the uplift calculation in the Ngungap area. The lowest terrace alows uplifting tectonic activity in the coast of Ngungap in the order of 5 mm/years. The uplift rate of southern coast of Wonogiri is different to the rate of active tectonic coastal areas in the eastern Indonesian region.

Published: October 2018

Emas letakan dasar laut maupun pantai Perairan Bayah terdapat dalam pasir, pasir sedikit kerikilan, pasir kerikilan, pasir lumpuran, lumpur pasiran, pasir lumpuran sedikit kerikilan dan lumpur pasiran sedikit kerikilan. Akibat lingkungan pengendapan terbuka Samudera Hindia; sedimen fraksi kasar pasir, pasir sedikit kerikilan dan pasir kerikilan cenderung berkadar Au lebih tinggi daripada sedimen fraksi halus di daerah ini. Berdasarkan pendekatan diagram Total Alkali Silika, batuan beku asal emas sekunder adalah dasit bagian dari Granodiorit Cihara sekitar 10 kilometer sebelah barat Bayah. Kemudian karena densitas emas yang besar (19,3), logam mulia ini cenderung terakumulasi di sedimen bawah permukaan daripada permukaan terutama di daerah pantai. Arus sejajar pantai dari barat yang melalui kompleks batuan beku Granodiorit Cihara kemungkinan membawa emas ke timur serta terjebak oleh morfologi teluk yang dibatasi tanjung Ujung Karangtaraje di sekitar muara Sungai Madur. Emas kadar tinggi banyak terdapat disini. Kata kunci : emas letakan, karakteristik sedimen, dasar laut, pantai Bayah Gold placer of seabottom and coastal zone of Bayah Waters occurred in sand, slightly gravelly sand, gravelly sand, muddy sand, sandy mud, slightly gravelly muddy sand and slightly gravelly sandy mud. Due to open Indian Ocean deposition environment; coarse sediments of sand, slightly gravelly sand and gravelly sand tend to have higher Au contents than fine sediments. Based on Total Alkali Silica diagram, igneous rock as the source of secondary gold is dacite which belongs to Granodiorite Cihara approximately 10 kilometers west of Bayah. Furthermore, due to its high density (19,3) gold tends to accumulate in subsurface sediments than surficial deposits especially in the coastal area. Longshore current from the west passing through igneous rock complex Granodiorite Cihara possibly brought along gold to the east which is trapped by bay morphology formed by Ujung Karangtaraje headland located surround Madur River mouth. High content gold was much accumulated in this area. Key words : gold placer, sediment characteristics, seabottom, Bayah coast
KARAKTERISTIK ENDAPAN SEDIMEN PANTAI TERHADAP PENGARUH LIQUIFAKSI DI KAWASAN PESISIR PANGANDARAN DAN SEKITARNYA, KABUPATEN CIAMIS, JAWA BARAT
Authors: Budiono Kris , Raharjo Purnomo 
Published: October 2018

Liquifaksi adalah salah satu bencana geologi yang berhubungan dengan kegempaan, dimana tekanan pori dalam tanah atau sedimen mengalami peningkatan akibat getaran, sehingga mengakibatkan aliran air ke arah permukaan tanah. Liquifaksi umumnya terjadi pada dataran rendah termasuk kawasan pesisir. Daerah penelitian yang terletak di sekitar pantai Pangandaran dan Parigi terdiri dari endapan lempung, lanau, pasir dan kerikil yang bersifat lepas dan jenuh air, secara regional sering dipengaruhi oleh kekuatan gempa antara 5,5 â€“ 6 skala Richter dengan percepatan tanah antara 150 â€“ 200 mgal. Kondisi seperti ini apabila terjadi gempa sangat memungkinkan untuk terjadi liquifaksi. Berdasarkan hasil perhitungan secara kuantitatif nisbah pori kritis, tidak semua lokasi penelitian akan mengalami liquifaksi pada percepatan permukaan 150 â€“ 200 mgal. Berdasarkan nilai tumbukan SPT yang dipakai untuk analisis â€œsimplified procedureâ€, daerah penelitian secara umum relatif kecil terhadap bahaya liquifaksi. Namun demikian berdasarkan korelasi antara sifat mekanik tanah dengan nilai SPT, pada kedalaman 0 â€“ 8 m terdapat lapisan sedimen yang cukup rentan terhadap liquifaksi. Kata kunci: Liquifaksi,sedimen pantai,Pangandaran Liquefaction is one of many geological hazards related to an earthquake, where the void ratio pressure in soil or sediment will increase due to the vibration, that causing water flow up to the ground surface. Generally liquefaction is occurred in the low lying areas including coastal zone. The survey area located in the Pangandaran and Parigi coasts, is consisted of clay, silt, sand and gravel, of loose and saturated properties, generally is frequently influenced by 5,5 â€“ 6 Richter scale of earthquake strength with the ground acceleration between 150 â€“ 200 mgal. The liquefaction will be occurred in this condition if there is an earthquake. Based on the quantitatively calculation of critical void ratio, the liquefaction at ground acceleration of 150 â€“ 200 mgal will not be occurred at all of the survey area. Based on the number of blows of SPT which is used for simplified procedure analysis, it shows that the study area is less influenced by the liquefaction. Nevertheless , based on the correlation between soil mechanic properties and SPT value, there is potential liquefiable sediments layer between the depth of 0 â€“ 8 meters. Key words: liquefaction, coastal sediment, Pangandaran

Effets premiers de l’intervention

Published: October 2018

Depuis de nombreuses années, la question de l’évaluation de l’intervention sur les Troubles Musculo squelettiques (TMS) et les Risques Psychosociaux (RPS) est une préoccupation pour tous les acteurs. Confronté à ces sujets complexes, l’intervenant est souvent mis en difficulté pour repérer les indicateurs de la pertinence du dispositif qu’il mobilise. La capitalisation des interventions menées au sein de notre Cabinet Conseil depuis 25 ans nous a permis d’identifier cinq signaux à détecter, précurseurs d’« effets premiers ». À partir de l’exemple d’une intervention menée dans le secteur des transports, nous proposons de les caractériser : une nouvelle lecture partagée de l’existant, une nouvelle appréciation de la valeur, une évolution du périmètre de l’intervention vers les activités managériales et organisatrices du travail, un élargissement des catégories d’acteurs « embarqués », et, une construction de nouveaux standards et outils de gestion qui se distinguent par une intégration des critères de santé et de performance économique.
The ISC-GEM Earthquake Catalogue (1904–2014): status after the Extension Project
Authors: Di Giacomo Domenico , Engdahl E. Robert , Storchak Dmitry A. 
Published: October 2018

Abstract. We outline the work done to extend and
improve the ISC-GEM Global Instrumental Earthquake Catalogue, a dataset which
was first released in 2013 (Storchak et al., 2013, 2015). In its first
version (V1) the catalogue included global earthquakes selected according to
time-dependent cut-off magnitudes: 7.5 and above between 1900 and 1918 (plus
significant continental earthquakes 6.5 and above); 6.25 between 1918 and
1959; 5.5 between 1960 and 2009. Such selection criteria were dictated by
time and resource limitations. With the Extension Project we added both
pre-1960 events below the original cut-off magnitudes (if enough station data
were available to perform relocation and magnitude recomputation) and added
events with magnitude 5.5 and above from 2010 to 2014. The project ran over a
4-year period during which a new version of the ISC-GEM Catalogue was released each
year via the ISC website
(http://http://www.isc.ac.uk/iscgem/, last access: 10 October 2018). For each year, not only have we added new events to the
catalogue for a given time range but also revised events already in V1 if
additional data became available or location and/or magnitude reassessments
were required. Here we recall the general background behind the production of
the ISC-GEM Catalogue and describe the features of the different periods
in which the catalogue has been extended. Compared to the 2013 release, we
eliminated earthquakes during the first 4 years (1900–1903) of the catalogue
(due to lack of reliable station data), added approximately 12 000 and 2500
earthquakes before 1960 and between 2010 and 2014, respectively, and improved
the solution for approximately 2000 earthquakes already listed in previous
versions. We expect the ISC-GEM Catalogue to continue to be one of the most
useful datasets for studies of the Earth's global seismicity and an important
benchmark for seismic hazard analyses, and, ultimately, an asset for the
seismological community as well as other geoscience fields, education and
outreach activities. The ISC-GEM Catalogue is freely available at

Statistical Fragility and the Role of P Values in the Sports Medicine Literature
Authors: Parisien Robert L. , Trofa David P. , Dashe Jesse , Cronin Patrick K. , Curry Emily J. , Fu Freddie H. , Li Xinning 
Published: October 2018

Introduction:
Comparative trials evaluating categorical outcomes have important implications on surgical decision making. The purpose of this study was to examine the statistical stability of sports medicine research.

Methods:
Comparative clinical sports medicine research studies involving anterior cruciate ligament, meniscus, and knee instability were reviewed in two journals between 2006 and 2016. The statistical stability for each study outcome was determined by the number of event reversals required to change the P value to either greater or less than 0.05. The number of patients lost to follow-up was also determined.

Results:
Of the 1,505 studies screened, 102 studies were included for analysis, 40 of which were randomized controlled trials. There were 339 total outcome events, with 98 significant and 241 not significant. The Fragility Index, or the median number of events required to change the statistical significance of the overall study, was five (interquartile range, 3 to 8) or 5.4% of the total study population. In addition, the average number of patients lost to follow-up was 7.9, which is greater than the number needed to change the significance of each study arm and the entire study population.

Conclusion:
Results in the comparative sports medicine literature may not be as stable as previously thought, with only a small percentage of outcome events needed to change study significance. Outcomes research based on a single discreet P value cutoff may be misleading.
