Abstract

In the context of tourism, supporting facilities such as shops / souvenir businesses has a strategic position in its existence, because it is ‘secondary travel needs’. This secondary travel needs are produced and marketed by a an art studio called Nggara Simbelin art studio located in Lingga village. This art studio is the supporting for tourism existence in the Karo District to date, which has been providing souvenirs based on wood, however this souvenir business has various problems. One of which is marketing,it is weak so that it sometimes results in a build-up of goods of those souvenir in the warehouse. During the 4.0 industrial revolution, information is not only as needs however it has become a primary need for millennials today, and nature and local creativity are highly valued interests for tourists. Therein lies the opportunity, where in this research will be packed as an advertisment in the form of a film teaser to support business marketing souvenir so that it can become a commodity information for millennial tourists who visited tourist sites in the Karo District. The movie teaser is expected to increase sales of souvenir products made from wood from Nggara Simbelin art studio in Lingga Village. This study uses the science of phenomenology, participant observation techniques, with data analysis: (1) data reduction; (2) presentation data; and (3) drawing conclusions / verification. The making of tourism films in this study uses 2 theories, a secondary theory, namely: the theory of film making with 3 working indicators: pre-production, production and postproduction of films, while the primary theory is: film theory as a tourism promotion media with 4 working indicators: color, features, properties and ratios. The results of the application of the seven working indicators of the theory produces a true tourism film as a tourism promotion media. From this research, the next study we will examine how is the impact of this advertisment on the sale of wooden souvenirs for the Nggara Simbelin art gallery.

Abstract

Electricity currently plays essential role to support the lives of modern society and national development in Indonesia. The use of renewable energy resources to produce electricity need to be continually encouraged since the exploitation of fossil energy sources to generate power have been depleting the energy reserves. In addition, the use of fossil energy pollutes for the environment. For these reasons, a lot of studies need to be carried out to find out the best possibilities to generate power using renewable energy sources.In this study an experimental investigation of the performance of a small-scale power generation system using an organic Rankine Cycle (ORC) system with a low-quality geothermal steam as the heat source is carried out. The experimental system was designed, built and tested using R134a as a working fluid. This small-scale power generation unit uses key components such as a vane type pump, to increase the pressure of the working fluid, the evaporator, to absorb heat from the heat source, the expander (turbine), to expand the heat vapour to generate work on shaft, and the condenser, to change the fluid phase into saturated liquid. Some parameters such as heating steam temperature and mass flow rate of the working fluid will be varied during the experiment to obtain the best system performance. From the test results it is obtained that the highest thermal efficiency of the system is 5.34% and the net output power is 1523.42 Watt. The experimental results show that using low-quality geothermal steam in the power generation system using this ORC system is feasible to use with acceptable performance.

Abstract

Pada tulisan ini dipaparkan tentang suatu kajian eksperimental yang telah dilakukan untuk menganalisa performansi dari sebuah unit pembangkit listrik sistim siklus Rankine organik (Organic Rankine Cycle) skala kecil yang memanfaatkan uap panas bumi berkualitas rendah sebagai sumber panas penggerak. Komponen-komponen utama dari unit pembangkit tersebut terdiri dari pompa tipe vane yang digunakan untuk menaikkan tekanan fluida kerja, evaporator dan kondensor sebagai alat penukar kalor serta turbin sebagai alat ekspansi, yang dibuat dari memodifikasi kompresor pendingin udara mobil jenis scroll. Sedangkan fluida kerja organik yang digunakan adalah R134a. Dari hasil pengujian ini didapat efisiensi termal sistim tertinggi sebesar 5,34% dan daya keluaran bersih sebesar 1.523,42 watt. Hasil pengujian menunjukkan bahwa penggunakan uap panas bumi berkualitas rendah pada sebuah sistim pembangkit listrik ORC ini layak untuk digunakan dengan kinerja yang dapat diterima.
