“…Im & Liu [11] indicate that such difference between return and supply temperatures does not succeed in reaching the design temperature of SH or operating temperature of auxiliary equipment, and more heat is required from a CHP plant. Moreover, these temperature levels are not acceptable when a heat distribution network operates in Russia within the context of outdoor temperatures of -30C and below [18]. The heat load profiles obtained here may be used as input for a simulation of a DH substation, including a heat pump [19] and a tank for thermal energy storage [6].…”

Proper adjustment of domestic hot water (DHW) load structure can balance energy demand with the supply. Inefficiency in primary energy use prompted Omsk DH company to be a strong proponent of a flow controller at each substation. Here the return temperature is fixed to the lowest possible value and the supply temperature is solved. Thirty-five design scenarios are defined for each load deviation index with equally distributed outdoor temperature ranging from +8 for the start of a heating season towards extreme load at temperature of -26°C. All the calculation results are listed. If a flow controller is installed, the customers might find it suitable to switch to this type of DHW supply. Considering an option with direct hot water extraction as usual and a flow controller installed, the result indicates that the annual heat consumption will be lower once network temperatures during the fall or spring months are higher. The heat load profiles obtained here may be used as input for a simulation of a DH substation, including a heat pump and a tank for thermal energy storage. This design approach offers a quantitative way of sizing temperature levels in each DH system according to the listed methodology and the designer's preference.

To prevent rain from eroding the sides of the trench we have developed a method of spraying them with hydro-seed. The homemade solution contains water, soil, mulch and a special blend of local grass seed. The mixture containing the blend of seeds enhances the soil to give it some strength and minimize the erosion. Another option is using concrete anchors instead of steel ones, which are supposed to increase the rigidity of a district heating (DH) network. The paper further visualizes the process with the materials required for each step. We constructed the equation in order to estimate net present value depending on the capital costs of the construction, the time of the cash flow, and the discount rate. In case of concrete anchors, the NPV of the project is negative. However, in case of hydro-seeding, the income provided by avoiding penalties becomes bigger than initial costs in the very first year of the project life span. From the comparison of two NPV profiles, the model combining the concrete anchors and the hydro-seeding can save up to 20% of investments compared to the conventional DH line. Results show that although then capital costs are increased by up to 24%, investment payback for DH network can be reduced to 12 years while life span can be increased by up to 30 years.

Master Plan Teknologi Informasi adalah sebuah hal yang sangat diperlukan untuk perencanaan selama beberapa tahun kedepan pada sebuah wilayah. Kabupaten Lombok Utara adalah Kabupaten yang baru berdiri dan membutuhkan master plan tersebut untuk mempercepat proses pembangunan khusunya dibidang teknologi informasi dan komunikasi. Wilayah Kabupaten Lombok Utara membentang sepanjang pantai utara pulau Lombok, dengan SKPD yang menyebar pada wilayah tersebut dan kontur yang berbukit. Pembuatan master plan untuk wilayah seperti ini dibutuhkan alat bantu yang berbasis peta digital yang memungkinkan melihat peta, rute, kontur dan jarak antar objek pada peta tersebut. Penelitian ini bertujuan untuk membangun alat bantu yang mempermudah pembuatan master plan yang dalam hal ini pada Kabupaten Lombok Utara. Pengembangan sistem ini dibuat menggunakan framework CodeIgniter dan menggunakan bahasa pemrograman PHP dan HTML, serta menggunakan Google Maps API untuk menampilkan rute, jarak dan ketinggian. Pengembangan sistem ini menggunakan 5 proses yaitu pendefinisian kebutuhan sistem, perancangan sistem, coding dan implementasi, pengujian dan dokumentasi. Pengguna dapat menentukan jenis jaringan yang akan dibangun pada suatu dinas SKPD berdasarkan hasil pencarian rute, jarak dan ketinggian lokasi tersebut menggunakan Google Maps API. Sistem ini menggunakan pengujian black box dan MOS. Berdasarkan hasil pengujian black box sistem dapat berjalan dengan baik, sedangkan untuk pengujian kuesioner MOS didapatkan hasil 53,54% responden menyetujui sistem ini.
