Abstract

The transfer of the provincial capital from Ternate to Sofifi caused almost allgovernment activities to be transferred to Sofifi. This is indicated by the increasingnumber of commuters who travel between islands with surrounding islands or districts(hinterland) or between regions within the city. Sea transportation as a means ofconnecting between islands is still very minimal, lack of infrastructure, limited numberof transportation to high transportation costs. The purpose of this study was to determinethe characteristics of PNS commuters in the island cluster area and analyze the chain ofcommuter PNS trips in the island cluster region in North Maluku province. Theinterview survey was conducted to determine various personal characteristics andpatterns of commuter travel chains. The results of this study are expected to provide anoverview of the characteristics of the computer travel chain in the island cluster regionin North Maluku Province.

Abstract

PLTU Tidore adalah pembangkit listrik yang berbahan bakar batu bara berkalori rendah untuk melayani kebutuhan listrik masyarakat khususnya di Kota Ternate dan Tidore. Dampak penggunaan batu bara menghasilkan limbah berupa fly ash dan bottom ash. Pada penelitian ini dicoba untuk menggunakan bahan bottom ash sebagai bahan pengganti parsial terhadap agregat pasir pada pembuatan paving block dan meneliti klas mutu yang dihasilkan. Berdasarkan hasil pengujian sifat fisik bahan bottom ash memiliki karakter yang lebih ringan dari pasir dan tingkat penyerapan diatas 20% yang 10 kali lebih banyak dari standar bahan untuk agregat normal. Sementara senyawa kimia dominan penyusun bottom ash memiliki kemiripan komposisi dengan bahan pasir dan juga bahan semen sehingga bahan bottom ash tidak memberikan pengaruh buruk terhadap reaksi semen saat pengadukan. Hasil pengujian kuat tekan sampel mortar paving block dengan variasi pengempaan 10 kN dan 40 kN diperoleh laju penurunan kemampuan tekan mortar berkisar antara 0,8 MPa hingga 5,3 MPa dengan nilai rata-rata sebesar 2,1 MPa setiap penggantian 10% bahan pasir dengan bottom ash. Begitu pula dengan tingkat penyerapan paving block yang dihasilkan mengalami peningkatan seiring dengan penambahan jumlah bottom ash pada pembuatan paving block. Akan tetapi meskipun dengan penggunaan bahan bottom ash pada pembuatan paving block menybabkan degradasi kemampuan tekan dan peningkatan peyerapan, paving block yang dihasilkan masih lebih dominan pada klas mutu B dan pengempaan dengan gaya yang lebih besar akan membuat massa paving block lebih padat lagi.

Abstract

Nikel laterit adalah produk residual pelapukan kimia pada batuan ultrabasa. Pelapukan pada peridotit menyebabkan unsur-unsur dengan mobilitas rendah sampai immobile seperti Ni, Fe dan Co mengalami pengayaan secara residual dan sekunder. Pulau Obi merupakan salah satu daerah yang dianggap prospek terhadap endapan nikel laterit terutama di Pulau Obi bagian Utara. Kandungan logam Ni (nikel), Fe (besi), dan Co (kobal), di daerah ini merupakan hasil pelapukan dari dunit. Penelitian ini melakukan pengkajian lebih spesifik mengenai penyebaran endapan nikel laterit khususnya di Pulau Obi, Kabupaten Halmahera Selatan, Propinsi Maluku Utara. Litologi daerah penelitian disusun oleh konglomerat, diorit dan dunit. Profil endapan nikel laterit daerah penelitian terdiri atas zona limonit, saprolit dan bedrock. Ketebalan zona limonit bervariasi dari 1 - 5 meter. Ketebalan zona saprolit mencapai 16 meter. Berdasarkan penelitian dapat disimpulkan bahwa profil geokimia di daerah penelitian menujukan terjadinya ketidak normalan distribusi unsur-unsur yang ada, baik unsur Ni, Co, Fe, SiO2, CaO dan MgO. Selain itu, ketebalan dan kedalaman endapan nikel laterit dapat bervariasi. Oleh karena itu perlu dilakukan penelitian yang lebih mendalam lagi mengenai penyebaran endapan nikel laterit karena setiap lokasi memiliki karakteristik yang berbeda.

Abstract

The use of thin-walled structures as energy absorbers has been widely known and applied in various fields. Thin-walled structures have the ability to absorb energy very well at various levels of impact speed. In this study, an analysis of the behavior of thin-walled structures with aluminum cone-shaped was carried out. This structure has a length of 200 mm thickness of 2 mm with one end whose diameter is left to remain 50 mm and the other end is made varied; 50 mm, 64 mm, 84 mm, 104 mm and 124 mm. A pounder made of cube-shaped steel measuring 15 cm x 15 cm x 15 cm weighing 26.49 kg pounding the specimen at a speed of 10 m / s so that the kinetic energy is received is 1324.7 Joules. Deformation with certain patterns in thin-walled structures and the results of the simulation obtained are total deformation, bending pattern, and energy per unit length. From the five specimens, it was found that the thin tube had a longer deformation than the cone shape. But the cone's ability to absorb more energy is indicated by the amount of energy per unit length.

Abstract

Ternate Region which was once the center of European power in the archipelago before being transferred to Jakarta by Governor-General Jan Pieterzen Coen. (1619-1623), who later renamed Batavia, was the V.O.C (Dutch East Indian Company) headquarters, the world's first multi-national company, for Southeast Asia centered on the Orange fortress Ternate. Orange fortress built by Cornelis Metalief de Jonge in 1606-1609. V.O.C. which recorded putting his governor in Ternate as many as 55 people from 1607 to 1810, depart from this history so up to now, the existence of Dutch buildings in the city of Ternate can still be found. The method used in this research, is a qualitative descriptive method that focuses on the overall description of the form, function, and periodization associated with the legacy of the Dutch Colonial Architecture in Ternate. The existence of colonial architectural heritage in Ternate becomes very important to maintain the existence of Ternate as one of the regions that have historical value in Indonesia. In order to support it, this research process becomes very important for the development of architectural science in Ternate City and the general contribution of this research is expected to complete the documentation about the development of the city of Ternate not only in terms of its history but in terms of its architectural wealth
