<![CDATA[This research aim to know the level of organic and anorganic giving best result to growth vegetatif rumput gajah (Pennisetum purpureum). This research was design by using Completely Randomized Design with the single treatment various level organic and an organic manure (P), that is p0 = control (without organic and an organic manure), p1 = 100% urea + 0% organic manure., p2 = 75 % urea + 25 % organic manure., p3 = 50 % urea + 50 % organic manure., p4 = 25 % urea + 75 % organic manure and p5 = 0 % urea + 100 % organic manure, each treatament repeated 5 times so that there are 24 experemintal units. The result of this research is level organic and an organic give the influence to hihg crop 6mst and 8 mst, amount of leaf 6 mst rumput gajah (Pennisetum purpureum). The component og growth show the same tendency, where the effect of organic manure given better result, coumtary with the anorganic manure]]>

<![CDATA[The internet has changed the life style of people and also the way people to communicate. After the existence of the internet, people can buy products from his home or office. Prior to the internet, people get information about a product through written advertising, but now the information can be quickly obtained or disseminated by the presence of second-generation internet, or Web 2.0 Customers can exchange information and influence each otherin product selection. This could happen through social media. Because the huge number of the social media users make companies use this medium, not only to inform but also to sell. Not all entrepreneurs succeed in this online business, but many also fail. This study proposes model developed by the Technology Acceptance Model (TAM) and Theory of Reasoned Action (TRA) to determine the factors that could affect the purchase intention online through Social Media Marketing. The data obtained from this study is 748, which is obtained through a question naire distributed at public universities and private individual in three cities in Indonesia (Surabaya, Malang and Banjarmasin). Confirmatory factor analysis was conducted to test the construct validity and reliability for each variable. By using Structural Equation Modeling (SEM) showed that the most influential factor on purchase intention is perceived use fulness, while subjective normin fluenced the purchase intention but had no effect on perceived usefulness. Keywords: social media marketing, structural equation modeling, technology acceptance models, theory of reasoned action ]]>

<![CDATA[The rapid development of mobile communication technology advances and cost reductions possible to incorporate mobile technology into the smart home system. We proposed a system of mobile and internet-based smart home consisting of a mobile phone with android, Internet-based applications, and server blynk. Home appliances can be controlled by an Arduino that receives commands from the server computer, which operates in accordance with commands received from the mobile application via a wifi network or the internet. In the proposed system, a home server is made using Wi-Fi technology that receives order from clients and orders will be processed through the Arduino, which allows users to control and monitor all the parameters associated with home using Andriod smart phone or via the internet. This study present the design of a low cost innovative and automated control based on weather conditions, the control apparatus, and home security together with android application to allow smart phones to send commands using blynk. Keywords: Smart Home, Arduino UNO, Wi-Fi, blynk ]]>

<![CDATA[Jenis penukar kalor sangatlah beragam dan masing masing dirancang untuk memenuhi kebutuhan yang spesifik. Namun demikian jenis shell & tube sejauh ini merupakan jenis yang paling banyak dipergunakan berkat konstruksinya relatif sederhana dan memiliki keandalan karena dapat dioperasikan dengan beberapa jenis fluida kerja. Efek pendinginan yang dihasilkan dalam sistem refrigerasi tergantung dari efektivitas kinerja kondensor. Sementara, kinerja kondensor semakin lama akan menurun seiring dengan terjadinya fouling factor. Pada penelitian ini dilakukan analisis optimasi sistem termal pada kondensor shell and tube sebagai Alat Penukar Kalor (APK). Dari hasil optimasi kondensor shell and tube dengan menggunakan analisis full factorial yang di validasi dengan sofware Heat Transfer Research Inc (HTRI) dan disimulasi Computational Fluid Dynamics (CFD). Didapat hasil optimum adalah diameter shell 720 mm, jumlah tube 192 buah, diameter tube 38.1 mm, panjang tube 3 m, beda temperatur rata-rata LMTD 8.86 K, dan dengan koefesien perpindahan panas menyeluruh U 1448.21 W/m2K. Dalam penentuan parameter temperatur desain kondensor sistem cooling-tower, harus mempertimbangkan kinerja cooling-tower dan perubahan temperatur udara.Kata kunci: kondensor, optimal, shell and tube]]>

Most organic rice farmers to sell their crops to traders and surrounding communities a place to stay at a price not much different from non-organic rice. During this organic rice sold in supermarkets comes from the island of Java, they can not sell to supermarkets because of limited capital. This study aims to identify the internal and external factors as organic rice agribusiness development efforts in South Kalimantan long-term goals give an idea to the public / investor on opportunities for organic rice farming that development of organic rice farming in South Kalimantan increased. The method used by purposive sampling and accidental sampling. Sample total 76 peoples. The result showed the strength of organic rice farming is the resulting product is beneficial to health. The main drawback is the limited capital. The biggest opportunity in terms of increasing farmers for fertilizer production technology and biological pesticides. The biggest threat that farmers have difficulty obtaining and maintaining organic certification. Keywords: Organic rice, External factors, Internal factors, Agribusiness]]>

<![CDATA[The biggest problem faced by the countries in the world including Indonesia is the energy problem. Currently, Indonesia has experienced an energy crisis that is very alarming. Availability of Fuel of the Indonesian nation dwindling even have to import from other countries. The purpose of this study was to determine the mileage when not using solar power and determine the mileage when using solar power, the expenses needed for electric motorcycles using solar power. The study was conducted using the method of theoretical and experimental approaches to get the parameters-parameters. The object of research was done on electric bikes with solar power. The research design used in data collection and the materials used to solve the problem by conducting interviews, frequently asked questions directly related to the problem. Of the trial data obtained power generated electric bicycle without using solar power has an average value on a flat road is 14.5 km / h, the uphill road is 10.9 km / h. While electric bikes using solar power has the average value on a flat road is 17.7 km / h, the uphill road is 13.7 km / h. Economic aspects of the comparison of electric bicycles to use solar power with gasoline motors are able to save costs in one year is Rp 1,348,000,- In a modification of the electric motor in the electrical circuit required to try neat.]]>

<![CDATA[City transportation in Banjarmasin is called Bamikro or Banjarmasin Mikrolet serves passenger transportation that consists of several types of cars / vehicles. The operation of this vehicle to serve the passengers is a problem for other vehicles. They often stop abruptly and do not attempt to pulll over the vehicle; have the passengers get into and off arbitrarily and often do not stop at the spots which have been provided (shelter). As a consequence of this vehicle, other road users’ forward movements behind it are interrupted. This vehicle tries to take the lane of another vehicle, causing a narrowing in a way resulting in disruption of roads taken and if it cannot take another lane because the lane is filled, then the vehicle is forced to stop for the completion of Bamikro to serve passengers. The length of the delay of the vehicles by the operation of Bamikro are calculated and the data collected and used in the calculation were obtained from the survey of traffic on the road segment by determining the result of (i) the percentage of Bamikro in traffic flow (ii) the frequency and duration of the stoppage. Keywords: Bamikro, Shelter, Frequency]]>
