Abstract

Information technology is required by the Faculty of Engineering UNDIP to support the achievement of faculty goals. This faculty has implemented and relied on information technology for administrative processes, teaching, and learning activities although in performing its business processes since 2004. The problem found was the practices of information technology have been expected by the Faculty of Engineering UNDIP, or not yet. Therefore, research on the governance of IT audit is necessary to know which management objectives are important, the current capability level, comparison of IT governance conditions in 2014, which management objectives have been achieved, and provide some recommendations. This research method uses the COBIT 2019 on two parameters of the DSS and MEA. Based on the results of the research, the current capability level of the Faculty of Engineering according to the DSS and MEA domain of COBIT 2019 is at level 1 (performed) with an average value of 36%. The Faculty of Engineering has decreased level, but the goal has been more or less achieved through the practices of a set of incomplete/disorganized activities.

Abstract

In 2017-2019, the Tanah Laut Regency, Banjar Regency, Banjarbaru City population was relatively high and continued to increase every year. The increase in the population reaches 1.39% to 2.92%. Along with population growth, the human need for clean water also increases, especially from groundwater. The study aims to assess the vulnerability of groundwater to contamination. The method used for the analysis of groundwater vulnerability to contamination is the DRASTIC method. It refers to seven parameters, namely groundwater depth (D), net recharge (R), aquifer media (A), soil layer (S), topography (T), impact to vadose zone (I) and hydraulic conductivity (C) by using geospatial analysis to calculate the DRASTIC Index/DI. From the results of geospatial analysis, there are three zones of groundwater vulnerability to contamination based on DI values, namely low vulnerability (95-106), medium vulnerability (106-146), and high vulnerability (146-186). The distribution of high zones dominates in the research area around of 75, 8%. The DRASTIC method requires a lot of data to provide an accurate analysis of groundwater vulnerability zone maps. This method has excellent accuracy and more effective in producing a map of the groundwater vulnerability zones to contamination.

Abstract

The increase in the need for residential land will encourage changes in land use functions. Monitoring the development of urban settlements in Kudus Regency, specifically in the Districts of Bae, Jati, Kaliwungu and Kota needs to be carried out so as not to cause a transfer of land use functions that deviate from the applicable RTRW. Monitoring can be done by modeling. The modeling of urban settlement development is then combined with GIS to support the spatial analysis. This study aims to determine the changes in land use function for urban settlements in 2010-2020 with the overlay identity method, apply the CA-Marcov method in predicting land use for urban settlements in 2030 and find the value of modeling conformity with the RTRW map and its development pattern using the average nearest neighbor. The data used are WordView images in 2010 and 2015, SPOT-7 images in 2020 and the RTRW Map of Kab. Holy year 2012-2032. The results showed that the development of urban settlements in 2010-2015 was 162,375 Ha, while in 2015-2020 it was 55,978 Ha. During 2010 to 2020, the food crop agricultural area changed its function into urban settlements amounting to 126,927 Ha. The area of land for urban settlements as a result of the prediction of land use in 2030 is 3323,285 Ha, where the agricultural area for food crops is the largest land converted into urban settlements of 321,803 Ha. The value of the suitability of the predicted use of 2030 with the RTRW map is 71.42%. The pattern of urban settlement development in 2030 is random.

Abstract

Selama ini dalam memahami bentuk spasial kota dilakukan dengan menggunakan kemampuan kognisi spasial pengamat untuk mendapatkan gambaran imajinasi struktur kota yang didalamnya terdapat hubungan elemen fisik satu dengan elemen fisik lainnya. Penelitian ini menawarkan teknik penggunaan kemampuan otak pengamat yang disebut neurosains agar pemahaman bentuk spasial kota lebih dari sekadar bentuk fisik yang berestetika, namun juga terkait dengan munculnya perasaan dan emosi dari pengamat. Penelitian ini bertujuan untuk membahas pendekatan neurosains dalam memahami bentuk spasial kota untuk melengkapi penggunaan kognisi spasial yang sebelum ini telah dilakukan oleh para peneliti lain. Manfaat penelitian ini digunakan sebagai salah satu instrumen dalam mengevaluasi desain ruang kota berdasarkan persepsi pengamat. Metode penggalian data dan informasi menggunakan teknik menggambar peta oleh pengamat dengan berfokus pada penguasaan area perkotaan beserta elemen-elemen fisik di dalamnya kemudian dilanjutkan dengan wawancara secara mendalam. Hasil penelitian telah membuktikan, bahwa pendekatan neurosains dalam memahami bentuk spasial kota telah menghasilkan pengkayaan pemahaman, tidak hanya pada pemahaman bentuk fisik struktur kota beserta elemen-elemen identitasnya sekaligus menyertakan respon emosi dan makna pengamat terhadap bentuk spasial kota

Abstract

The research was conducted at the Dinding A and Dinding B, Moronopo Site PT Antam Tbk, East Halmahera, North Maluku which is a block that has been opened for the mining process. Generally the stratigraphy of laterite nickel deposits, from top (young) to bottom (old) consists of overburden, limonite, saprolite and bedrock. The saprolite zone is an economical ore layer for Ni content. This research aims to determine the relationship between grain size of ore and the mineralogy and economical Ni content. The research methods used include the grain size fractionation method with sizes of -5 cm, +5 cm, +10 cm, +15 cm, +20 cm and +25 cm, and XRF analysis to determine the Ni content. The result of this study shows the rocks in the saprolite zone containing minerals such as olivine, serpentine, garnierite and chrysoprase. The XRF analysis result shows the highest Ni content is found in the finest grain fraction (-5 cm) i.e. 2.4% and the lowest Ni content found in the coarsest grain fraction (+25 cm) i.e. 1.87 % but  is still classified as economic.

Abstract

Ball and beam system (BBS) is a commonly used model to represent several complex and unstable systems. BBS is underactuated system. It is an ideal model to implement kind of control theory. Most of control design are done using simulation method. This method is not realistic because it is conducted on the ideal situation which implies that the result cannot be directly used to control the real system. Hardware in the loop (HIL) simulation is a method that can be used to solve these problems. The use of real controller makes the design experience more realistic and ready to implement. This paper proposes a design of full state feedback for BBS stabilization using HIL simulator. The contribution of this work is to design state estimator on the BBS setup to estimate position and velocity. The result shows that the proposed control and estimator are successfully implemented. The estimator can estimate the output position with time convergent about 1,32 second. The performance of the system is similar with simulation and real plant implementation. It shows that this method can represent the dynamic response of the system on full state feedback control.
