(1) Background: The visual impact of artificial infrastructures on natural landscapes generates a common negative perception in public opinion. However, as in the case of electrical energy, the increasing demand for power supply and its need for capillary distribution require the installation of new lines, commonly overhead lines with tall tower-like pylons. In most countries, this situation is faced with many attempts of solutions, as participatory workshops and design contests. Nevertheless, the solutions are usually not further developed into real structures due to many limitations (e.g., regulatory, safety, lack of feasibility). (2) Methods: This paper presents a systematic method for the design of tower-like pylons (e.g., electric ones) able to improve the visual quality on the landscape areas in which they will be installed. The method identifies a design strategy that advantageously exploits the inevitable visual impact of pylons on the landscape by integrating the symbolic morphology and the topologically optimized pylon structure from the earliest design phases. (3) Results: The resulting structure is designed in three steps. First, a concept is morphologically developed by integrating symbolic references to the landscape, environment, or cultural society. Second, the concept is topologically optimized, by reducing the structural weight and its visual impact, and respecting regulatory requirements. Third, the resulting structure is engineered and embodied into an industrially feasible layout. (4) Conclusions: The method is able to develop an original, brand new tower-like pylon integrating all the types of requirements, such as regulatory, industrial feasibility, and social components’ needs. The resulting electricity pylon presents an enhanced visual quality according to the citizens’ feedback.

Control And Monitoring System

The increasing demand for electrical energy and the decreasing supply of fossil fuels in recent years have increased the cost of electrical energy. So that the culture of saving electrical energy is a habit that must be cultivated in the community. On the other hand, energy-saving behavior cannot be realized massively without a support system that can control energy use. With these concerns, it is necessary to develop a method that encourages a culture of saving electrical energy. This paper proposes a system that supports active energy efficiency methods that can support an energy-efficient culture. This system is an electric power monitoring system that is integrated with a smart electrical panel that continuously monitors the use of electrical energy and can control electrical loads automatically, record electricity usage, provide comprehensive reports and analyze energy usage. The method used to carry out this research is research and development. This research has produced a prototype of electrical power control and monitoring system that has a smart panel based on a raspberry PI 3 and PZEM-004t power energy meter. The monitoring system performs and executes automatic control of electrical loads. The system can also provide reports in the form of data monitoring in daily, weekly, monthly or annual period. From the test results, it can be concluded that the system can work well. This research is expected to contribute to providing a system that can support government efforts in saving energy.

Visual Impact Assessment

Visual impact assessment studies are reasonably substantial to understand an environment which has different features. The aim of this study is to evaluate the visual impact of the Istanbul Land-wall and contribute to future design/planning stages. For this purpose, the study area was separated into four different spatial usages which are recreational, transportation, agricultural and neglected places. Twenty-four different photographs were taken and a survey was conducted upon an expert and a public sample group. The public survey included four parameters: well-kept, exciting, safety and beautiful scenery. The expert survey also involved four parameters which were coherence, imageability, stewardship and historicity. One-way ANOVA test was conducted to reveal sample groups’ effect on the preferences. The results showed that the average scores of photographs evaluated by public and experts were 11.07 and 9.80 scores respectively. In the public survey, the photograph, has the lowest scores for all parameters, was Photo-11 (P11). Experts’ result shows particularly that historicity is lower than the others although the area is a historical region. Specifically, neglected places obtained lower scores than the other spatial types. Consequently, the Istanbul Land-wall does not have adequate visual quality regarding the selected parameters.

ResumenLa creciente demanda de energía acompañada de los elevados niveles de emisión de gases contaminantes a la atmosfera hace patente la necesidad de encontrar nuevos sistemas de producción de energía. Una de las posibles alternativas se encuentra en la energía solar de concentración, y más concretamente en la tecnología termosolar con motor Stirling que alcanza unos niveles de rendimiento muy superiores a la energía solar fotovoltaica en cuanto a producción de energía eléctrica. En este trabajo se muestra el diseño y la caracterización de un prototipo de captador paraboloidal con motor Stirling, que permite obtener datos reales del funcionamiento de este tipo de sistemas. Esto permitirá modelizar de manera real el comportamiento esperado de equipos comerciales reales antes de abordar su implantación en edificios y viviendas unifamiliares.AbstractThe increasing demand for energy accompanied by high level of emission of the contaminating gases into the atmosphere underscores the need to find new energy production systems. One of the possible alternatives is concentrating solar power and, more specifically, solar thermal technology with a Stirling engine that reaches higher performance levels than photovoltaic solar energy in terms of electricity generation. This paper shows the design and characterization of a prototype paraboloidal collector with a Stirling engine that allows obtaining real data of this type of systems functioning. This will allow modelling in a real way of expected performance of real commercial devices before approaching their introduction in buildings and single-family houses.

ABSTRAK. Beberapa penelitian melaporkan cara negara-negara di berbagai belahan bumi melestarikan kualitas visual lanskap. Tingginya apresiasi terhadap lanskap membuat mereka selalu melakukan sebuah penilaian atau assessment setiap adanya penambahan struktur baru pada lanskap. Hal inilah yang membuat kualitas visual mereka tetap terjaga dari kerusakan baik yang disengaja maupun tak disengaja. Di Indonesia, perhatian ini masih lemah dan belum ada peraturan dari pemerintah yang khusus mengaturnya. Penelitian ini mencoba melakukan penilaian terhadap kualitas visual pembangunan Rumah Sakit Medika Dramaga yang didirikan pada tahun 2012. Proses proyek dan setelah proyek memiliki beberapa efek yang harus diperhatikan. Salah satunya adalah dampak visual konstruksi pada lanskap sekitarnya. Tujuan dari penelitian ini adalah untuk 1) menganalisis dampak visual dari kegiatan pembangunan Rumah Sakit Medika Dramaga bagi masyarakat sekitar yang dilihat dari aspek natural resources dan cultural resources; dan 2) mengidentifikasi persepsi dan preferensi masyarakat sebagai user utama. Hasil dari penelitian ini berupa rekomendasi perlindungan visual setelah adanya pembangunan Rumah Sakit Medika Dramaga terhadap lanskap sekitarnya. Penelitian ini menggunakan metode visual impact assessment (VIA) dengan menggunakan pendekatan dari Ogawa. Hasil penilaian menunjukkan bahwa kualitas visual Rumah Sakit Medika Dramaga umumnya dapat diterima secara visual, namun perlu dilakukan sedikit tindakan mitigasi (modifikasi kecil) untuk menghilangkan kontras visual yang terjadi dengan lingkungan. Kata kunci: kualitas lingkungan, lanskap, penilaian dampak visual, kualitas visual ABSTRACT.
