Efek Jenis Kemasan terhadap Kualitas Gabah dan Beras Varietas Cigeulis

Produksi gabah dan beras selama ini menghadapi masalah penurunan mutu akibat penyimpanan yang kurang memadai. Penelitian ini dilakukan dengan tujuan untuk mengkaji efek jenis kemasan terhadap kualitas gabah dan beras varietas Cigeulis selama penyimpanan. Penelitian dilakukan di Batang Ase, Kabupaten Maros, Sulawesi Selatan yang dimulai pada bulan Juni 2006 hingga Desember 2007. Rancangan yang digunakan adalah acak kelompok pola faktorial dengan faktor pertama adalah kemasan (kemasan karung plastik dan kemasan hermetik) dan faktor kedua adalah lama simpan (0,3,6,9 dan 12 bulan). Percobaan dilakukan terhadap 10 petani sebagai ulangan yang masing-masing 10 karung gabah yang dikemas hermetik dan 10 karung gabah yang dikemas karung plastik. Tiap karung diisi 50 kg gabah yang disimpan di gudang milik masing-masing petani hingga 12 bulan. Tiap 3 bulan gabahnya digiling untuk mendapatkan beras. Hasil penelitian menunjukkan bahwa penggunaan kemasan hermetik dapat menghambat kenaikan kadar air gabah varietas Cigeulis selama dalam penyimpanan (10,76%), mempertahankan persentase beras kepala (84%), menekan butir patah (24,45%), kerusakan gabah (1,67%) dan tingkat hama rendah (2,4%) saat penyimpanan 12 bulan. Hasil organoleptik menunjukkan bahwa nasi dari gabah kemasan hermetik tetap baik dan enak dari awal penyimpanan hingga 12 bulan penyimpanan baik kelekatan, rasa, warna, kepulenan dan aroma, sedangkan nasi dari gabah kemasan karung plastik mengalami Perubahan yaitu nasi makin kurang melekat, warna putih kusam dan aroma berkurang. Daya tumbuh gabah memperlihatkan perbedaan yang nyata antara yang disimpan dengan kemasan hermetik (99% penyimpanan 9 dan 12 bulan) dan kemasan karung plastik (11% penyimpanan 9 bulan dan 0% pada penyimpanan 12 bulan)

Effective Communication As a Tool for Achieving Organizational Goals

Communication is a key element of human behaviour. In other words, it is an act by which one person gives to or receives information from other person about that person’s needs, desire, knowledge, opinions and perceptions. Communication in the workplace can occur under many different modes such as writing, verbal and nonverbal (body gestures and facial expression). In business and industry, communication helps to align workers to work with one another and to achieve the objective of the organization, which means objectives, can be in the target, attained and improved. Without workplace communication, nothing can be done.     Keywords: communication, organization, workplac

Graph splicing rules with cycle graph and its complement on complete graphs

Graph splicing system is a notion originally used to illustrate the one-dimensional string of DNA splicing in the form of a graph. A graph splicing system is associated with a graph splicing scheme where graph splicing rules are defined. A graph splicing rule restricts the possible cuts to occur on the edges of the initial graph(s) in a graph splicing system. The subgraphs of the initial graph are used in the splicing rules to determine the edges that will be cut from the initial graph. The concept of graph splicing system can be applied on various types of graph, hence generates components of spliced graphs depending on the types of the graph splicing rules used. There is a graph splicing rule called as a cutting rule which can be applied on both linear graphs and circular graphs where the graphs are transformed into Pseudo-Linear Form. However, this cutting rule has limited various possible cuts that can occur on the complete graph. Therefore, in this research, the original concept of graph splicing system is applied on complete graphs as the initial graphs. Also, graph splicing rules involving subgraphs of the initial graphs which are also complete graphs, are considered and applied in the graph splicing system. Furthermore, the generated spliced graphs are obtained through the graph splicing system

Effect of Surface Hardness on Joint Contact Forces during Barefoot Running: A Pilot Study

This paper presents an experimental pilot study on the effect of different surface hardness to the joint contact force during barefoot running. Peak joint contact forces during the stance phase of a male subject that running barefoot on three types of surface with different hardness level (concrete, artificial grass and rubber) were investigated experimentally. Differences in peak joint contact force at the ankle, medial tibiofemoral, lateral tibiofemoral, hip and patellofemoral due to surface effects were analysed using Freebody (Version2.1) software. The result showed that the pattern of peak joint contact force was similar for ankle with medial tibiofemoral and hip with lateral patellofemoral. The joint contact force was varied in the varying of the surface hardness. The correlation between various surface hardness and joint contact force was found at the ankle and medial tibiofemoral joint. However, the findings of this pilot study provide the insight into the method and approach selected for the experiment be suitable for an actual experiment for more subjects

Generation of dark pulses in a bismuth tellurite based mode-locked erbium-doped fiber laser

We report on the formation of dark pulses in a highly nonlinear fiber laser passively mode-locked by a Bistmuth Tellurite (Bi2Te3) based SA. The SA was fabricated by embedding Bi2Te3 powder into polyvinyl alcohol (PVA) film by a solution casting technique. By inserting the SA into an EDFL cavity, stable mode-locked operation was achieved at 1592.68 nm with the maximum pulse energy up to 2.38 nJ by adjusting polarization controller. The laser operated at pulse repetition frequency of 1.0 MHz with a pulse width of 215 ns. These results suggested that Bi2Te3 could be developed as an effective SA for mode-locked dark pulses generation in a highly nonlinear cavity

Incidence and antibiogram of Vibrio parahaemolyticus in processed and frozen bivalve mollusks in Kuala Terengganu, Malaysia

This study aimed to investigate the prevalence and antibiogram of Vibrio parahaemolyticus in processed bivalve molluscs in Kuala Terengganu. A total of 80 seafood samples, namely mussels (n=20), carpet clams (n=20), cockles (n=20) and scallops (n=20), were subjected to PCR and conventional plating method for the detection of V. parahaemolyticus. V. parahaemolyticus was found in green mussels (55%), carpet clam (80%), cockles (40%) and scallops (55%). Fifty-five V. parahaemolyticus isolates were subjected to 9 types antibiotic sensitivity test using discs diffusion method. All isolates were susceptible to Tetracycline and Gentamycin. Isolates showed high resistance towards Vancomycin (52.73%), Penicillin (45.45%) and Amplicillin (32.73%). Resistance towards Amikacin, Ciprofloxacin and Norfloxacin were found to be 1.82%. It can be concluded that local bivalve molluscs were contaminated with V. parahaemolyticus and isolates showed resistance towards certain antibiotics. Therefore, consumption of raw or semi-cooked bivalve molluscs is not advisable
