Abstract

Control and operation of a microgrid can be operated at grid connected or islanded modes. In this paper, the microgrid consists of a Diesel, PV modules with a distributed energy storage system, loads, and inverter. The purpose of power management is to control the stability of the system to cope with changes in load and interconnection with other networks. The stability of the microgrid is also obtained by setting the load connected to the system. Power management is also controls the operation of each plant based on the condition of the energy sources used as a source of generation. In islanded mode, the main goal of power management is to stabilize the system, in terms of frequency and voltage. In grid connected mode, typical objectives are to minimize the price of energy import at the point of common coupling (PCC).

Abstract

Cultural heritage is a cultural richness of the nation as a manifestation of human life’s, thoughts and behaviors that are important for understanding the history as well as the science and culture of our ancestors. In East Java there are two cultural heritage areas have been selected by the government: Penanggungan (as of January 14, 2015) and Trowulan (as of December 30, 2013) as provincial and national cultural heritages, respectively. In this research, we built a geoportal data infrastructure for collecting, storing and visualizing the spatial distribution of cultural heritages in these two areas as one of the role in maintaining the preservation of cultural heritages. Based on our geoportal data, the location of cultural heritage located in the elevation ranged from 228 m- 1330 m (above sea level). The lowest cultural heritage was Situs Belahan and the highest one was  Temple of Kama I. Trowulan Site has 75 artifact findings. This indicated that the Trowulan Site area was a residential area. While in Penanggungan site, the heritage was dominated by cultural object in the form of temple (about 32 object). It might be an indicator that Penanggungan site was  a basis for ancient community worship rituals.

Abstract

Terminal Nilam Timur merupakan terminal yang mempunyai peruntukan dalam pelayanan komoditi curah cair di Pelabuhan Tanjung Perak. Meningkatnya arus kunjungan kapal di Terminal Nilam Timur dalam melayani komoditi curah cair (CPO) selama ini belum diimbangi dengan adanya pertumbuhan infrastruktur yang memadai, sehingga mengakibatkan rendahnya kegiatan operasional. Sementara itu jumlah dermaga yang digunakan untuk melakukan kegiatan bongkar muat sangat terbatas, sedangkan dari segi waktu cenderung sangat fluktuatif. Oleh karena itu dibutuhkan adanya analisis untuk mengetahui kinerja operasional Terminal Nilam Timur serta arah perbaikannya. Metode yang digunakan dalam kajian ini yaitu analisis deskriptif kondisi eksisting dengan SK–Dirjen Hubla, metode Important Performance Analysis. Kajian ini menghasilkan kinerja operasional dari segi aspek pelayanan kapal yang dinilai kurang baik pada tahun 2015 adalah ET:BT dan waktu pemanduan. Aspek pelayanan barang selama 4 tahun terakhir pencapaian kinerjanya dinilai kurang baik. Sedangkan aspek pelayanan utilitas fasilitas yang mempunyai nilai kurang baik tahun 2013. Berdasarkan analisis kinerja menurut persepsi pengguna jasa dengan metode IPA didapatkan atribut pelayanan yang memerlukan prioritas utama perbaikan yaitu waktu tunggu kapal untuk antri sandar di dermaga (waiting time berth), jumlah ketersediaan peralatan bongkar muat, produktivitas bongkar muat, kecepatan bongkar sesuai dengan penetapan, panjang/jumlah dermaga, tingkat pemakaian dermaga, ketersediaan tangki penimbunan (Silo), ketersediaan tempat berteduh di Terminal Nilam.

Abstract

        Now,  procedures of design for the earthquake resistance of buildings and non-building structures SNI 1726: 2012 has been approved the procedures for seismic design for buildings SNI 1726-2002.  SNI 1726: 2012 refers to the development  of  modern seismic regulations are due to changes in tectonic plates located on the active track on the path of circum-Pacific and the Indian track - the Himalayas. With the enactment of the new  SNI earthquake,  namely SNI 1726: 2012, then all existing buildings and designed with old  SNI earthquake, that  is SNI - 1726-2002 should be evaluated against for the new regulations. Handling scheme for existing buildings should be made to determine and improve safety. Analysis and solutions are required to improve the safety of buildings. Retrofitting Seismic Isolation is one of  the effective and practical methode to increase safety of buildings against earthquakes, because  this methode can reduce the earthquake acceleration response. Retrofitting seismic isolation can not only improve the safety and functionality seismic, but also to maintain the original design. Without the need to demolish and rebuild the building, the building will remain intact. So that historic buildings and cultural heritage can still be preserved. The concept of base isolation is to decouple the upper structure from its foundation and inserting isolator which has a small horizontal stiffness. This techniques can reducing the seismic impact from the soil vibration which could be from seismic motion. This study will compare the ratio building safety for old structural design that uses SNI-1726-2002 (old) vs SNI 1726: 2012 (new). The results shows that retrofitting seismic isolation building have better performance in terms of ductility demand, natural period, and lower internal forces due to earthquake.
