Fluorescence imaging and fluoresence spectrocopy are methods that can be used to detect the Ripeness level of sapodilla fruit (sawo fruit) based on the maximum fluorescence intensity. The development of efficient and economical fluorescence imaging system is needed to analyze the post-harvest ripeness of sapodilla. In this research, fluorescence imaging system was built using LED 680 nm as the laser source and CMOS 3 MP camera as a detector. LED was used to induce fluorescence on the sapodilla fruits. The samples used were Sapodilla Manila (Manilkara zapota (L.) van Royen) with two measurement variations. The first measurement was done on sapodilla with 3 levels of ripeness, those were ripe, half ripe, and unripe. The second measurement was done on the half ripe fruit for 6 day period. The image of fruit that was illuminated by LED light was recorded using the CMOS camera. Fluorescence intensity was presented in RGB plot using Image-j software. The relation between fruit ripeness level and the maximum fluorescence intensity was analyzed. The results of research on the first methods showed that the average fluorescence intensity of ripe sapodilla was higher than those with half ripe and unripe sapodilla fruits. The maximum fluorescence intensity indicated a different level of ripeness. The difference of fluorescence intensity between ripe and half ripe sapodilla is 7,8%, the difference of fluorescence intensity between ripe and unripe sapodilla is 35,9 %, and half ripe sapodilla had a difference of 30,9% with the unripe sapodilla. The results of the second method showed that at the fourth day, sapodilla was already in the process of rotting. On the second day to the fourth day, the fluoresecence intensity has increased. The fifth day and the sixth day, the fluorescence intensity has decreased linearly.

(2016-05-23) Riawan, Dadhe; Saktioto; Zulkarnain
A density of plasma thermal carbon ion species has been successfully simulated with the software program Matrix Laboratory (MATLAB). The code is designed from the continuity equation by time function and the Arrhenius Equation. The code is run by entering the coefficient charge each reaction and Arrhenius parameters formed as a matrix. The Arrhenius parameters are α, β, and γ. Six reaction of plasma forming the carbon species depend on the Arrhenius from as a function of temperature. Carbon ion plasma density is calculated to reach thermodynamic equilibrium at atmospheric pressure. The temperature of plasma used is the same for all species with a value of 0.5 eV and integration of time is 10-9 seconds. The density are integrated by the time with Runge-Kutta method. Time range for the species to reach thermodynamic equilibrium is 10-9 – 10-8 seconds. A results of the thermodynamic equilibrium of carbon ion plasma densities are ne= 1019.09 m-3, nC= 1024.09 m-3, nC+ = 1022.09 m-3, nC2+ = 1021.09 m-3, nC3+ = 1021.09 m-3, nC4+ = 1021.09 m-3, nC5+ = 1021.09 m-3, nC6+ = 1021.09 m-3. These show that the equilibrium can be achieved at a certain value of time but unstable condition.
Peran Entrepreneurial Markeung Dalam Meningkatkan Kinerja Usaha Mikro Kecil Menengah (Umkm) Di Indonesia
(2015-01-21) Zulkarnain
Terinspirasi dari buku Entrepereneurial Marketing yang ditulis Leonard M. Lodish di Wharton Business School yang terdiri dari 14 bab diantaranya meliputi; product development, pricing, advertisement, distribution channel, promotion, sales management dan brand management, dan Marketing That Works yang berusaha mengakhiri "perang paradigma" antara pemasaran dan kewirausahaan. Buku yang ditulis Leonard M. Lodish, Howard L. Morgan dan Shellye Archambeau ini menyajikan sisi taktikal pemasaran sehingga mudah untuk diimplementasikan oleh perusahaan pada semua skala, termasuk UMKM adalah untuk memberikan alat bagi pengusaha ventura untuk mendapatkan keuntungan maksimal dari biaya minimal yang dikeluarkan untuk aktivitas pemasaran. Ketiga penulis mengkritisi pentingnya memilih berbisnis dengan pasar sasaran yang tepat, banyaknya pengusaha yang terlalu percaya diri terhadap produk yang mereka pasarkan. Mereka meninggalkan suara konsumen, dan hanya mengandalkan intuisi mereka, dalam bahasa pemasaran, situasi ini dinamakan "marketing myopia" (rabun pemasaran) yang berisiko tingginya rasio kegagalan pada usaha baru.
