The position of Ki Hadjar Dewantara road is strategic location, where as an education center, office and residential center are often happened to increase in vehicle volume, especially during peak hour, consequently, this condition makes congestion on this road. There are ideas for road widening, moved side barriers and one.way traffic management, which are purposing to know traffic performance currently and generating a recommendation of traffic systems. By observations on traffic surveys were carried out on the road at 06.00 to 18.00 WIT. Traffic performance analysis is based on the 1997 Indonesia Road Capacity Manual (MKJI). The results of the Ki Hajar Dewantara road analysis showed a high level of side resistance with a value of degree of saturation (DS) in segment 1, which was 0.78, free flow speed of 31.2 km / hour, road capacity of 1953 pcu / hour. Furthermore, as an alternative solution the application of a one way system on the road section that showed a better performance with DS = 0.32 for west to east and DS = 0.22 east to west with a service level B category with stable current, speed slightly limited by traffic, the driver has enough freedom to choose a speed. The design for implementing this one-way system is good for solving problems.

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.

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.
