Perkembangan suatu kota mengakibatkan meningkatnya suhu udara di kota tersebut. Kondisi ini biasa dikenal sebagai efek Urban Heat Island. Hal ini berdampak pada aktivitas yang terjadi di ruang kota. Koridor Sultan Khairun (salah satu ruang kota/street) yang berorientasi Utara-Selatan, saat ini telah berkembang pesat dengan didominasi oleh fungsi komersial dan ramai dikunjungi oleh masyarakat kota Ternate. Terkait dengan hal tersebut kenyamanan termal menjadi suatu hal yang penting dan tersedia bagi pengguna. Penelitian ini bertujuan untuk mengetahui penataan hardscape dan softscape terhadap aspek nyaman termal pada ruang publik kota. Metode yang digunakan adalah metode pengukuran empirik dan simulasi menggunakan software Envi-MET. Hasil penelitian menunnukkan bahwa pada koridor Jalan Sultan Khairun didominasi oleh bangunan dengan ketinggi 1-2 lantai dan minim vegetasi yang hanya terdapat pada salah satu sisi jalan sehingga temperature rata-rata 32 derajat pada siang hari lebih panas. Simulasi koridor dengan vegetasi rapat dan kerapatan bangunan rendah dikedua sisinya agar angin bergerak sehingga dapat mengurangi panas oleh sinar matahari.

Solar Street Lighting a street lighting solution for areas or areas that are not within the PLN network area or for lighting efficiency using solar power. The use of public street lighting, although it has several advantages, there are still disadvantages in the field conditions, including the improper placement of the lighting so that it is blocked from sunlight, the use of inappropriate materials, unsuitable height of poles and lack of maintenance which results in not optimal utilization of solar energy. In this study, an analysis of the power efficiency of solar street lighting in the District of Ternate Island will be carried out by conducting direct observations and measurements in the field. The results showed that the maximum voltage for street lamps that were not blocked by trees was 23 volts, while those that were blocked by trees were 19 volts. The lighting strength of the street lights that are blocked by trees is 9 lux, while those that are not blocked by trees are 10 lux. The amount of input voltage for the solar panels affects the strength of the lamp lighting

The problem of the need for electrical energy, especially petroleum as a source of energy is decreasing, so that savings must be anticipated as early as possible. One of the saving measures taken to reduce the use of petroleum in order to meet electricity needs is to use water energy as renewable energy, so in this study PLTMH is planned. The things that are taken into account in planning PLTMH are conduits, water tanks, rapid pipes, powerhouses, turbines and generators. The PLTMH research was conducted in Tawa Village, Gane Barat Selatan District, South Halmahera Regency. The results obtained are a water discharge of 0.28 m3 / s and a waterfall height of 12 meters, a diameter of 12 cm of rapid pipe, a length of 19.20 m of rapid pipe. kW, and the generator is sporadically coupled so that the net power of the turbine is equal to the gross power of the generator. The efficiency of the generator is 90%, so that it produces a rise power of 18.88 kW divided by cos φ which is equal to 23.6 kVA
电能需求的问题，特别是作为能源来源的石油的需求正在减少，因此必须尽早预期节省。减少石油的使用以满足电力需求的节约措施之一是将水能作为可再生能源，因此本研究规划了PLTMH。在规划PLTMH时要考虑的是管道、水箱、快速管道、发电站、涡轮机和发电机。PLTMH研究是在南哈马赫拉县Gane Barat Selatan区Tawa村进行的。实验结果表明:水流量为0.28 m3 / s，瀑布高度为12 m，快速管直径为12 cm，快速管长度为19.20 m。kW，与发电机偶联，使汽轮机的净功率等于发电机的总功率。发电机的效率为90%，因此它产生的上升功率为18.88 kW除以cos φ，等于23.6 kVA
