"As the imbalance of automotive market competition continues, the domination of foreign industries demands a proper attention from Indonesia’s automobile manufacturers. Efforts in creating a national car design that is emotionally attached to Indonesia’s automotive market, will be able to meet the challenge appropriately, in part by using the Kansei Engineering Type 1: Category Classification method. Identified through literature studies and interviews, there are 164 Kansei words that represent the exterior designs of a 4×2-wheel drive passenger car. The Kansei words were categorized into 12 groups using an affinity diagram and then arranged into a five-level semantic differential scale for product samples assessment. Results were further processed using factor analysis, leaving nine groups remaining. A collaborative design process with a product designer resulted in an exterior design of a hatchback car with four doors. Scores from the evaluation on Kansei word groups “satisfying”, “luxurious”, “sporty”, “aesthetic”, “innovative”, “mobile/flexible”, “complicated/complex”, “credible”, and “masculine” indicate that the car exterior design meets users’ emotional needs."

"The aim of this studywas to examine and compare psychological factors influencing car drivers? andmotorcycle riders? speeding intentions (IN), using the Theory of PlannedBehaviour (TPB). The psychological factors modules included Attitude (AT),Subjective Norm (SN) and Perceived Behavioural Control (PBC). These wereemployed to explain speeding intentions in urban road environments. A sample of188 car drivers and 174 motorcycle riders were collected from the twouniversities within Khon Kaen, Thailand. The Structural Equation Model (SEM)was used to examine and explain speeding intentions. The results indicated thatthe TPB could explain 33% and 41% of the variance of intentions by car driversand motorcycle riders, respectively. The most significant psychological factorfor car drivers was determined by attitude (AT), while the speeding intentionof motorcycle riders was attributed to perceived behavioural control (PBC). Theauthorities in Khon Kaen Province should determine safety policies that canimprove these psychological factors, which could have various effects oroutcomes on changing car drivers? and motorcycle riders? speeding intentions.The outcome of this study could help to understand car drivers? and motorcycleriders? speeding intentions in urban road environments and it could be usefulfor development of safety measures."

"AbstrakBeton adalah hasil campuran yang diperoleh dengan cara mencampurkan semen Portland, air dan agregat (halus dan kasar) serta bahan tambah, yang sangat bervariasi mulai dari bahan kimia tambahan. Beton digunakan sebagai struktur dalam konstruksi bangunan dapat dimanfaatkan untuk banyak hal. Seperti untuk struktur beton digunakan untuk bangunan pondasi, kolom, balok, pelat atau pelat cangkang. Semen sebagai perekat banyak type/jenis semen namun yang dijual (dipasarkan) ada semen yang disebut semen OPC (ordinary Portland Cement) dalam kemasannya disebut type I dan semen PPC (Portland Puzzoland cement). Penelitian ini, adalah membandingkan dan mengetahui mutu atau kualitas beton dengan menggunakan Semen PPC sebagai penganti dari semen type I. Dari hasil pengujian dengan membuat benda uji kubus dengan ukuran 15 x 15 x 15 cm dibuat 20 buah dengan umur uji 7, 14, 21,dan 28 hari serta masing-masing umur lima buah. Perlakuan pembuatan benda uji sama antara pengunaan semen type 1 dan semen PPC. Pelaksanaan pengujian dilakukan di Laboratorium Teknik Sipil Politeknik Negeri Medan, beton dibuat dengan menggunakan berat dari masing-masing bahan sesuai rencana, selanjutnya bahan tersebut diaduk dengan molen, setelah adukan merata dituang kedalam cetakan kubus 15 x 15 x 15 cm dan dipadatkan dengan rojokan menggunakan tongkat besi sampai merata, lalu diratakan dan di catat tanggal pembuatannya, setelah benda uji dibuat berumur 24 jam cetakan dibuka dan direndam dalam bak perendaman, sehari sebelum pelaksanaan pengujian sesuai dengan umur yang diinginkan benda uji dikeluarkan dari bak perendaman selanjutnya diuji kuat tekan dengan dengan alat tes kuat tekan, selanjutnya hasilnya diolah sesuai dengan jenis semen yang direncanakan. dihitung kuat tekan beton sesuai umur dan di hitung kuat tekan rata-rata sesuai umur benda uji. Hasil pengujian untuk umur 7, 14, 21, dan 28 hari semen type I 140 kg/cm, 180 kg/cm2, 186 kg/cm2, dan 175 kg/cm2, sedang semen PPC 139 kg/cm2, 171 k/cm2, 168 kg/cm2, dan 148 kg/cm2. Dari hasil pengujian serta pengolahan data maka dapat disimpulkan semen type 1 lebih tinggi dengan umur 7, 14, 21, dan 28 hari , yaitu 0,71 % , 3,9 %, 9,8%, dan 15,43 % kualitasnya dari semen PPC."

"Universities play an important role in motivating young graduates to become technology entrepreneurs. The objectives of this research are to investigate the success factors for business incubators and to develop and propose a framework of successful business incubators for public universities in Indonesia. Indonesian public universities that have business incubators were considered for this research. A preliminary study was conducted with a panel of experts who have the necessary insights and experiences in managing both the incubators and the relationships within the incubators with the tenant firms.This research examines some significant measures with reference to the unique features of university business incubators in order to better understand the manner in which incubators can be assessed in a developing country. The result of this research includes a framework of successful business incubators in Indonesian public universities. This framework is developed on the basis of previous studies and the preliminary study conducted with ten business incubator experts."

"Literature studiesindicate that information technology (IT) clusters encourage innovation andincrease firm-level productivity by providing external economies and facilitatingjoint action for its members. The purpose of this study is to identify theexternal economy and joint action factors that affect firm innovation andproductivity in the IT cluster. A research model was developed based on earliermodels of joint action and external economies. The model consists of three externaleconomy related factors, i.e., access to skills, finance, and infrastructure, aswell as three joint action related factors, i.e., vertical, horizontal, andresearch and development (R&D) cooperation as the independent variables,firm innovation as the intervening variable, the firm?s absorptive capacity asthe moderating variable, and firm productivity as the dependent variable. Datacollection was conducted through a survey with respondents from 32 IT firmslocated in three clusters in Bandung and one cluster in Cimahi (West Java ?Indonesia). The partial least square (PLS) approach was used for hypothesestesting. The results indicate that horizontal cooperation, access toinfrastructure, and access to skill have a positive impact on productivity,while horizontal cooperation and R&D cooperation have a positive impact oninnovation. Finally, firm innovation is proven to positively influence firmproductivity."

"An active Radio-Frequency Identification (RFID) tag is a low-power device, which is often used as a tracking device, where operation of this tag will be in remote areas from an electrical power source. Therefore, this device requires an independent power source. To meet these needs, solar power may be used, which can be accessed anywhere there is sunlight. Supercapacitors (SC) are used as an energy source to support a solar power system. The advantage of supercapacitors, as an energy storage device, is their long life cycle that means more charging and discharging processes compared to a conventional battery. The design and fabrication of a solar power system for an active RFID tag with supercapacitors as the energy storage will be covered in this paper."
