Expansion or establishment of new regions (Provinces, Regencies/Cities) is a consequence of the politics of decentralization implemented in Indonesia. The development of decentralization in Indonesia underwent fundamental changes after the reformation in 1998. Inception of UU No 22 tahun 1999 concerning regional government has given a new color to the administration of government in Indonesia or what is called broad autonomy. Restructuring regional governments that provide discretion in the form of broader authority in running their government in accordance with regional needs has created many implications for the region, one of which is stretching and the spirit of the region to bloom. In determining the boundaries of forming new regions, the geospatial aspect is an important and strategic aspect. Problems related to geospatial aspects such as maps of regional boundaries, area size, etc are issues that need to be clearly defined and calculated in the new (autonomous) regional (Province, Regency/City) determination. But in fact the law on the formation or establishment of regions in the period 1950-1999 on the geospatial aspect did not become an important part so that it caused problems later which could potentially trigger social conflicts such as regional boundary disputes. Post-reformation, the development of the role of the geospatial aspects has evolved a little more advanced, such as the existence of regional boundary maps in the appendix to the law on the formation or expansion of new regions, such as UU No 7 tahun 2002, UU No 2 tahun 2003, and others. However, there is still something that must be evaluated regarding the map in the attachment to be in accordance with the geospatial rules. A very progressive development in terms of the geospatial aspect is in UU No 20 tahun 2012 concerning the formation of the Kalimantan Utara province that utilizes geospatial data properly

A considerable amount of research has already been conducted into the nature of water on the ocean floor/seabed, ranging from mapping of the seabed, volume backscattering strength (SV) of acoustics on the seabed, classification of the seabed, besides the relationship between the ocean floor and the biota above it with which it interacts. The Yos Sudarso Bay, Jayapura Papua, is a bay with a seabed which faces the floor of the Pacific Ocean and also forms the estuary of the river Anafre which contributes particles that settle on the seabed. This research aimed to collect data in order to understand differences in the integration of water thickness at 0.2 m and 0.5 m besides differences in the types of the substrate based on the results of SV. Data was collected using a single beam echosounder. The acoustic data were collected at 11 stations. The result is interval of value of SV ranged from -37.81dB to -15.62 dB (at the integration of 0.2 m) up to -15.07dB (at the integration of 0.5 m). The value of SV from the gravel was higher compared to the values found in the coarse sand, fine sand, mud mixed with sand or the pure mud. The lowest value of SV was found in the mud substrate. Results showed that thickness integration yielded different results when tested at 0.2 m and 0.5 m on the seabed. Furthermore, it was found that different types of substrate.

Abstract Poverty alleviation programs in Indonesia are the same and uniform in all regions. Of course this ignores the characteristics and causes of poverty that vary in each region. The uniformity of poverty alleviation programs affects the slow pace of decline in the poor population. Spatial influence on poverty can be identified by spatial autocorrelation; there is a relationship of poverty in one region with other regions that are closed together. This study was aimed to analyzing poverty spatial distribution in all regencies/cities in Indonesia; analyzing the spatial distribution patterns of poverty in all regencies/cities in Indonesia; and knowing local spatial autocorrelation of poverty in all regencies/cities in Indonesia. The research methods used are Moran Index analysis, Moran’s scatterplot analysis, and Local Indicators of Spatial Autocorrelation (LISA) analysis. The analysis results show that the highest average of poor population percentage was in Papua and the lowest one was in Kalimantan. The results of analysis of Moran Index showed that the spatial distribution pattern of poverty in regencies/cities in Indonesia was clustered, it was called by poverty pocket. Pockets of poverty that occured do not correspond to government administrative boundaries, therefore poverty alleviation needs an integrative approach. In addition, this study also results that not all regencies/cities have significant spatial autocorrelation. This means that not all poverty conditions in a regencies/cities have a relationship with other regencies/cities. The fact that there are heterogeneity of poverty characteristics like this shows that poverty alleviation programs must vary in each regency/city.

Batam as a region with a strategic position, located on the international trade route, was developed to become one of the engines of economic growth in Indonesia. However, in its development, Batam faced governance problems that had an impact on the decline in its economic performance. Not only at the local level, but its influence reaches the national level. This study explains the causal relationship of Dual Governance, focusing on aspects of formation, relations between institutions and their impact on development. Using the framework of Holzinger, Kern and Kromrey (2016), this study captures the issue of institutional dualism that has occurred for years and is considered to be the cause of the decline in development in Batam. The study was conducted using qualitative research methods with a case study approach and collecting data from interviews and document analysis.There are several concluding points in this study regarding institutional dualism and its impact on economic development based on Batam’s case. They are the implementation of decentralization, the significance of the pre-existing institution, the similarity between two institution in respect of interpreting and implementing policies and the relationship between intergovernmental relations and economic development. These three factors affect the degree of intergovernmental relations which is directly proportional to economic development. The more intergovernmental relations are, the higher economic development is.

Publisher : Politeknik Negeri Batam

One of the environmental parameters that need to be monitored is ocean waves. Waves that occur at sea have random, dynamic, and complex movements. Height measurements and wave periods are difficult to formulate accurate and simplification is needed through mathematical equations in the form of sinusoidal. Therefore, the marine information system is very important for data storage media, data processing, and visualization of measurement data so that it is monitored in real-time. This research was made to build a website-based coastal wave height monitoring information system for wave height data display data from the measurement of the wave buoy instrument. This research was conducted by utilizing data from a wave height measuring instrument that was transmitted to an online database. Wave height data is displayed in the form of real-time data, real-time graphs with data sampling of 30 minutes, average data for one day, and average data for one month. Keywords: Wave height, system information, real-time

This research was conducted in the village of Hargowilis, Kokap District, Kulon Progo Regency with a temperature of 31oC, with a wind speed of 13 km/h, 55% air humidity, and a height of 35 m from the ground surface. This research was carried out on November 8, 2019 with hot weather conditions and wind speeds of around 13 km/hour. The purpose of this study is to map the drought area in Mount Menoreh Hargowilis Village, Kokap, Kulon Progo. The method used in this study are preparation for making a drone, survey of area Menoreh hills in Hargowilis, Kokap, Kulon Progo planning testing at certain altitude in the air; calibration drone; taking aerial photograph in area long dry and then analysis of data then mapping the area in Hargowilis, Kokap, Kulon Progo. Calibration drone DJI Spark is the way to calibrate the drone is automatically. When the drone is turned on it automatically calibrates the accelerometer; gyrometer; and GPS Drones use rotors for propulsion and control. Rotating rotors push air down, to be able to fly forward, it requires a push from the rotor. When the rotor presses air, air pushes the rotor. Lift force to control the force up and down. The faster the rotor rotates, the greater the lift. Multicopter has the advantage of being stable against wind speed. The battery capacity of drone is 2200 mAH with camera DJI Spark. Drone time used in this study ranges from 15 minutes at a speed of 30 mph. Aerial photo results show that the Hargowilis area, Kokap, Kulon Progo Regency experienced a drought so that the Menoreh Hills became a deforested forest. Keywords: Drone, Long Dry, Mapping, Photography, Kokap
