Langsa City is one of the City in Aceh Province that suffer from flood disaster almost every year. This research aims to analyze the extent of preparedness of community disaster response of Gampong Seulalah Langsa Lama in Langsa City in the event of the flood disaster. The type of this research is experimental research with phenomenology method. Data processing is done by performing data organizing, reading, and coding. The researchers also made an edge note of the data obtained. Furthermore, researchers conducted development of textural description and structural description. Finally, the researchers described the data obtained. The results of this study indicate that the level of preparedness of community disaster response of Gampong Seulalah Langsa Lama Sub-district in Langsa City is still low. This is due to the level of public awareness on the importance of disaster risk reduction through the response to the disaster is still very minimal. Advice from researchers, the need for a rigorous training effort to increase public awareness on the importance of community disaster response attitude to minimize the risk of the flood disaster. Good disaster preparedness will generate a good response and may minimize disaster risks.

A Multitools instrument was developed to measure physical variables such as temperature, magnetic field, and light intensity. Multitools developed using the device of ATMEGA 8535 microcontroller that consists of three sensors: LM35 as a temperature sensor, LDR as a light sensor, and UGN3503 as magnetic field sensor. The design consisted of three stages, namely system design, hardware design, and calibration phase. The calibration test result of Multitools shows alignment level of the temperature sensor 0.9893, light sensor 0.9787 and magnetic sensor 0.9996. Measurement result displayed in physical quantities data and graph on the LCD screen of Multitools. The Multitools can be used in physics lab activity to reduce the effectiveness and train the students’ skill in understanding and interpreting the graph.

Microtremor is a weak vibration on the surface of the earth that takes place continuously due to sources of vibration such as earthquakes, human activities, industry and traffic (Daryono, 2009). Microtremor data measured obtained 3 signals whose components are vertical (Up and Down), horizontal (North-South), and horizontal (East-West) components. After the signal is obtained it can then be analyzed using the HVSR method and the dominant frequency and amplification values are obtained. The HVSR method compares the spectrum ratio of the horizontal component microtremor signal to its vertical component (Nakamura, 1989). Lhokseumawe City is administratively included in the Province of Nangroe Aceh Darussalam (NAD). In 2004 there was an earthquake of magnitude 9.2 on the Richter Scale in the southern waters of the city of Banda Aceh, which caused a devastating Tsunami. In this event many people lost about 250 thousand lives and lost property that is not small in number (Logan, 2014) Due to the active regional tectonic pattern, the NAD region is a disaster-prone region. The tectonic area of NAD is strongly influenced by the subduction area between the Indian-Australian oceanic plate (Indian Australian Plate) against the European-Asian continental plate (Eurasian plate). The tectonic pattern greatly influences the geological conditions in the waters of the study area. The purpose of this research is to provide preliminary knowledge in the use of microtremors for mapping seismic microzonation. This microzonation mapping is needed for earthquake disaster mitigation purposes, microtremor data analysis can provide information on the value of a place that is very important for earthquake resistant building planning. Building structures that have the same value as the land value will experience resonance in the event of an earthquake. Then the last is the Seismic Vulnerability Index Mapping which is useful for predicting unconsolidated sediment zones at the ground surface when an earthquake occurs, so that further studies for earthquake prone areas can be carried out. The stages of the research method carried out are measuring field data which is divided into several measurement points in each district in the city of Lhokseumawe. At each measurement point, a three-component seismometer is installed to obtain the results of the soil’s vulnerability in the area. Each measurement data is observed for 30 minutes at each point. The results of this study are the existence of areas that are very susceptible to seismic namely Ujung blang and Banda Sakti villages with seismic vulnerability index values (Kg) ranging from 0 cm/s2 -30542.32 cm/s2 The highest value is located at Ujong Blang villages which is 10397.1 cm/s2 This is closely related to the total amount of damage to buildings in Lhokseumawe City due to the 2004 earthquake.

This descriptive qualitative research aims to identifythe implementation of the merit system principle in promotions and mutations carried out in Majene Regency after changing leadership, and to propose recommendations to improve the process. The study uses primary data in the form of in-depth interviews and studying archives and documents. The findings show that the merit system principle is not properly implemented in filling echelon III positions, with political and emotional closeness factors still dominating the process. However, the echelon II positions are filled more appropriately. The mechanism for filling positions in Majene Regency consists of promotions, rotations, and demotions. To improve the process, the study recommends the establishment of clear and technical rules, a clear career pattern, and providing a place for State Civil Apparatus (ASN) talents who have the ability as structural officials. This study provides valuable insights for the improvement of the promotion and transfer process in Majene Regency and similar regions facing similar problems.
