Analisis Vegetasi Tumbuhan Di Kawasan Resort Bantimurung, Seksi Pengelolaan Taman Nasional Wilayah II Camba, Kabupaten Maros, Sulawesi Selatan
No full textKepulauan Sulawesi kaya dengan flora dan fauna, memiliki 5000 spesies tumbuhan berbunga yang tercatat, dan 15% diantaranya adalah endemik. Ciri khas fauna Sulawesi adalah ketergantungannya yang kuat terhadap. Sulawesi Selatan yang merupakan bagian dari Kepulauan Sulawesi memiliki kawasan hutan lindung yang luas. Salah satunya adalah Taman
Nasional Bantimurung Bulusaraung. Luas Taman Nasional Bantimurung Bulusaraung adalah ± 43.750 ha dan merupakan kawasan hutan lindung yang memiliki potensi sumber daya alam hayati dengan keanekaragaman yang
tinggi.
Tanaman Nasional Bantimurung Bulusaraung meliputi areal kawasan hutan seluas 43,750 Ha yang terletak di Kabupaten Maros dan Pangkep Provinsi Sulawesi Selatan. Kawasan ini ditunjuk berdasarkan Keputusan Menteri Kehutanan Nomor : SK.398/Menhut-II/2004 tanggal 18 oktober 2004. Sebelum berubah fungsi menjadi Taman Nasional, kawasan ini
berfungsi sebagai cagar alam seluas 10.282,65 Ha, taman wisata alam seluas 1.624,25 Ha, hutan lindung seluas 21.343,10 Ha, hutan produksi tetap seluas 10.355 Ha, serta hutan produksi terbatas seluas 145 Ha. Alih
fungsi kawasan ini menjadi taman nasional didasarkan atas pertimbangan bahwa : kawasan tersebut merupakan ekosistem karst yang memiliki keanekarangaman hayati yang tinggi dengan jenis- jenis flora dan fauna endemik, unik dan langka. Keunikan fenomena alam yang khas dan indah
serta ditujukan untuk perlindungan sistem tata air

Development of Intensive Shrimp Farming, <i>Litopenaeus vannamei</i> In Land-Based Ponds: Production and Management
No full textThe Potency of Bacilus sp as Particle-associating Bacteria in Laboratory Condition
No full textThe aim of this study was to know the potency of Bacillus sp in colonizing artificial particles in laboratory condition. Study of particle –associating capacity of Bacillus sp by using artificial-sphare agar as particle and transprant exopolimeric particles (TEP) produced by Thalassiosira weisfloggii as well as flocculating activity. The results of this study showed that Bacillus sp were able to associate both artificial agar spheres and transparent exopolimeric substances (TEP) as well as high flocculating activity produced by phytoplankton, T. weissfloggii. The mean number of Bacillus sp in colonizing artificial agar spheres increasing with incubation time was 3,50 x 105 cells/agar spheres and Transprant expolimeric particles, 2.9 x 108cells/mL; and flocculating activity, 92 % after four days incubation. In conclusion that Bacillus sp has a high potential as particle-associating bacteria used in intensive shrimp farming system. Keywords: Particle–associating bacteria, Thalassiosira weisfloggii, Bacillus sp, Phytoplankto
Potensi Bakteri Zoogloea Sp sebagai Bakteri Pembentuk Bioflok pada Sistem Pertambakan
No full textThe objective of this study was to know the potency of bacteria zoogloea sp as indigenous bacteria from shrimp pond farming in colonizing particles. Study of particle-colonizing capacity of Zoogloea sp by using artificial-sphare agar and transparant exopolimeric particles (TEP) produced by fitoplankton, Thalassiosira weisfloggii. The results showed that Zoogloea sp were able to coloninize both artificial-agar spheres and TEP produced by T. weisfloggii.The mean number of Zoogloea sp colonizing artificial-agar sphares increasing with incubation time was 2,70 x 104 cells/agar sphere. In the test of TEP-colonizing bacteria showed that Zoogloea sp was able to colonize the TEP i.e. 2.5 x 108 cells/mL. after 4 days incubation. It can be concluded that Zoogloea sp isolated from shrimp pond farming has a high potential in colonizing particles
Simplified Madymo Seated Human Body Model for Motion Comfort Evaluation
No full textPeople need to have a comfortable experience in vehicles nowadays. However, they are continuously exposed to vibrations from the vehicle. Madymo active human models (AHM) can be used for comfort analysis and to learn how vibrations influence the human body in several aspects. However, existing AHM are very time-consuming due to their complexity, and the correspondence with human comfort data is only reasonable. In order to more effectively analyze motion comfort, a computationally efficient simplified human model (SHM) is developed and validated. The human body model has 36 degrees of freedom (DoF) considering the following segments: pelvis, two thighs, two lower legs, two feet, lower torso, upper torso and head. The model is validated in fore-aft, lateral and vertical vibrations. The model's postural stabilization parameters are tuned manually, by gradient search and grid search in sequence. Manually tuning gives a group of initial values of parameters for further optimization. According to the results, failure of the gradient search illustrates that this optimization problem is non-smooth. At the same time, grid search gives a relatively better result but also shows that the current cost function does not perfectly represent a good fit and needs improvement. A comparison between AHM and the SHM shows that the SHM has a similar or even better fit for most signals while being a largest factor 116 faster. A comparison of parameters between SHM and multibody human models in the literature shows that the structure of models affects the values of the same parameters. A comparison of different time steps illustrates that shorter time step does not necessarily give higher accuracy for this SHM. Suggestions such as adding muscles and changing body shapes are given for further improvement.Mechanical Engineerin
