Abstract

This study aimed to evaluate the different magnetic results of an electromagnetic induction with proton magnetometer measurements on an archaeological site. The electromagnetic induction allows measuring both the apparent magnetic susceptibility in part per thousand (ppt) and the apparent electrical conductivity in millisiemens (mS/m). A proton magnetometer measures the total magnetic intensity in nanotesla (nT), caused by the induced and remanent magnetisations. An archaeological site where historical documents indicated the presence of a 13th century fortress that built by Lamuri Sultanate was selected as a test area. The measurement were conducted by divided the study area into 10 profiles.Some standard data processing have been applied to the measured data. The result of the first survey with electromagnetic induction showed low magnetic anomalies in the buried remains of Lamuri fortress. The similar value are shown as well by low magnetic field intensity in magnetometer measurement.

Abstract

Gravity method was carried out at Seulawah Agam Area to delineate the existence of geothermal source, which is specifically existed in both the geothermal filed of Heutsz’s Crater and.Cempaga’s Crater. The Seulawah Agam is located in Aceh Besar district. Geologically, the area is dominated by volcanic mudflow and Lam Teuba’s rocks having age from Tersier to Resen Period. The equipment used includes Gravimeter CG-5 Autograv, Portable GPS (Global Positioning System), Navigation type (map of the survey area), computer and the other technical supports, such as handy talky, umbrella, watch, pens and observed data notes. This research was conducted by doing two stages.  Firstly, establishing the base station which is a reference point for all gravity data measurements at each point. Secondly, measuring gravity data at each point by repeating three times following looping pattern as pathway of measurement either in Heutsz’s crater whose nine points recording or in Cempaga’s crater whose seventeen points. The data was simply processed using Microsoft Excel that can just plot the Bouguer anomaly and interpreted qualitatively due to preliminary research. The resultof this research has shown that both areas have two kinds of Bougeur anomalies which slightly attract attention who’s high and low anomaly. At Heutsz’s Crater has high and low density existed at F125 FR and B6 point. The Point whose high density means that it was formed mineralization by hydrothermal process through fracture materials, meanwhile the point whose low density indicates that there is existed the fault which is quite related to Seulimum’s Fault based on Aceh map. This result is also same as obtained at Cempaga’s Crater which means also same interpretation. In addition, it can be sum up that fault zones are essentially important in geothermal system that plays vital role in term of fluid circulation. Employing the gravity method in this research effectively can be said

Abstract

Groundwater availability is the main concern in a developing region such as Weh Island, Aceh. To locate groundwater resources, vertical electrical sounding (VES) was used to identify subsurface profiles. The study area is located on a volcanic island. The lithology consists of volcanic rocks as andesite lava and pyroclastic rocks as lapily-tuff until breccia. VES method was carried out in 4 measurement points using the Schlumberger array. The resistivity value used to identify subsurface lithology. The top layer of alluvium and weathered lava have resistivity ranges from 14.3 Ωm to 17.7 Ωm with thickness varies from 0 m – 17.4 m. It is followed by andesite resistivity ranges from 17.3 Ωm to 18.2 Ωm with averages thickness is 17.4 m – 35.2 m. Finally, the bottom layer is filled by breccia-tuff with resistivity value from 5.5 Ωm to 7.3 Ωm. The physical properties of some related rocks allow water accumulation to their bodies. The current polarization indicates water content in the pore space of breecia at the study area which polarization point is identified as the water table.

Abstract

Based Health Research (2013) reported that the prevalence of anemia in pregnant women in Indonesia about 37.1%. Iron Deficiency Anemia is a health problem associated with a high incidence and complications that may arise on the mother and fetus. The aims of this study was to determine the correlation between the intake of iron (Fe) and vitamin C with iron deficiency anemia for pregnant women in Tua Tunu, Gerunggang, Pangkalpinang in 2015. This type of research was descriptive analytic study with cross sectional design. The total samples were 30 pregnant women. Measurement of hemoglobin was done by using the Easy Touch GcHb. The intake of iron (Fe) and vitamin C obtained by the method of 24-hour food recall for 5 times on days that are not consecutive. The correlation intake of iron (Fe) and vitamin C with iron deficiency anemia status were analyzed by Pearson product moment. These results indicate that 86.7% of pregnant women were inadequate intake of iron (Fe) and there were 80% of pregnant women inadequate for vitamin C. The number of pregnant women had iron deficiency anemia about 56.7%. The results of the analysis showed that there was a significant correlation between the intake of iron (Fe) and vitamin C with iron deficiency anemia status (p value = 0.000). Based on these results, it is recommended to pregnant women to do improvement for intake of iron and vitamins C and for the prevention of iron deficiency anemia problem needs to do Monitoring for Drug Intake and the provision of Multiple Micronutrient (MM).

Abstract

Citizens are one of the elements of state formation because the state cannot be formed without citizens. The link between the two is citizenship. Each country has different methods in determining citizenship in the country. Regulations regarding citizenship in Indonesia are listed in Law number 12 of 2006. The Republic of Indonesia uses the principles of ius soli and ius sanguinis in determining citizenship status. Indonesia basically adheres to the principle of single citizenship where one person is only allowed to have one citizenship. However, there are exceptions for children from mixed marriages who have the opportunity to have limited dual citizenship before they are 18 (eighteen) years old or married. This is regulated in article 6 of Law number 12 of 2006 concerning Indonesian citizenship. However, in practice there are still many Indonesian citizens above 18 (eighteen) years old and who do not meet the requirements to obtain limited dual citizenship status. Explained in Article 23 of Law No. 12/2006, the legal consequences that will be accepted if this happens are the loss of Indonesian citizenship status.

Abstract

Quality and Quality in the manufacturing industry in addition to emphasizing the products produced, it is also necessary to pay attention to the quality and quality of the production process. Thus, the final product produced is a product that is free from defects and there is no more waste that must be paid dearly because the product must be discarded or reworked. To maintain and improve the quality of the products produced, it is necessary to have quality control for the company. With quality control, it is expected that the products produced are in accordance with the standards set and deviations that occur can be immediately overcome. The Six Sigma method is a statistical concept that measures a process related to defects or defects. This method is considered as a method that is able to take a comprehensive approach, which will dramatically improve the quality of the resulting product. With the implementation of the Six Sigma method, CV. Bintang Terang Medan is expected to minimize the number of defective products to zero defects.
