The effect of pulsed light on the survival of E.coli MTCC 433 in tender coconut water was investigated. The sterilized liquid samples were inoculated with E.coli @ 1010 cfu/ml and treated with pulsed light intensities of 0.18, 2 and 5.6 W/cm2 for an exposure time between 0 and 15 sec. The results obtained were fitted with three different models such as log linear plus tail, Weibull and biphasic model. Biphasic model showed the best the performance with 7 smaller RSME values of 9 evaluated kinetics followed by Weibull model. Among the three models, biphasic model fitted well with the inactivation of E.coli MTCC 433 by using pulsed light treatment

This study aims to determine the physical and mechanical properties of coconut trunks based on 4 factors of acacia bark extract concentrations (0%, 10%, 15%, 20%) and the percentage of reduction in thickness (0%, 30%, 40%, 50%). The results showed that the average value of coconut wood moisture content is not compacted relatively higher compare to the average levels of condensed water. The average value of the coconut wood density was not relatively lower compared to the average density of the compacted. The average value of MOR and MOE coconut wood once compacted experience increased with coconut wood are not compressed. But all the values MOR coconut wood on this study is classified into strong wood class V. From the results of this study concluded that the process of compacting the coconut wood and soaking treatment using the extract of acacia bark may increase the value of physical and mechanical properties of coconut wood. Coconut wood compaction technology can be utilized as a substitute for wood raw materials but can not be used to hold the load.Keywords : coconut wood, physical properties, mechanical properties

Background: Football players requires a high level of VO2max which is influenced by the available of energy. Tender coconut water and branded isotonic are as energy drinks containing of carbohydrates and the body’s electrolyte ions that can prevent dehydration. The increasing pulse describes a the condition of dehydrated players during match or training. Objective: To Examine comparison of tender hybrid coconut water and branded isotonic to pulse and the plyer’s level of VO2max in the Diponegoro University Football School in Tembalang, Semarang. Methods: Experimental study with an approach of randomized pretest - post test control group design at 41 soccer’s player aged 13-15 years at Diponegoro University Football School Tembalang in August 2015. The treatment group consumed consumed 250 mL tender coconut water (n=13) and branded isotonic (n=14) and group control consumed mineral water (n=14) every 15-30 minutes for 5 times. Observation  pre test and post test 1,2,3 with interval of 3 day after physical training, athlets test the pulse to palpation techniques for 15 seconds and VO2max test with multistage fitness test. Result: The VO2max and pulse recovery in the beginning of research for 3 group was similar (p = 0,454 and p = 0,294). Post test 1 VO2max on three group are same (p = 0,841) but the recovery pulse is better on the group of tender coconut water and branded isotonic (p = 0.006). Post test 2, VO2max and recovery pulse is more good by players who were given tender hybrid coconut water and branded isotonic (p = 0,004 and p = 0,017), as the same post test 3 VO2max and recovery pulse (p = 0.000 and p = 0,004).Conclusion: Giving the tender hybrid coconut water and branded isotonic to same to recovery pulse and increased VO2maks on athlete school football diponegoro unversity

The purpose of this research is to know the mechanical properties (MoE and MoR) and the bonding strength of laminated board made of coconat wood and jackfruit wood, based on the number of layers (3 and 5 layers) and the axial part of the stem (base and top) with 1,5 cm board thickness. The results showed that the mechanical properties (MoE and MoR) and bonding strength for 3 and 5 layers of the base of the stems were better than the 3 and 5 layers of the top part. Characteristics of laminated board decreases from the base of stem to the top of stem. The higher number of layers, MoE value tend to decrease, on the contrary MoR value tend to increase.  PVAc glue properties can make good bonding strength with low wood damage percentage. The results of this study showed that the best axial direction used in the manufacture of laminate board is the base of the stem. The result of laminated board can be used as construction materials of light building, furniture and other interior equipments.Keywords : Coconut wood; Jackfruit wood; laminated board; mechanical properties; bonding strengthTujuan penelitian ini adalah untuk mengetahui sifat mekanika (MoE dan MoR) dan keteguhan rekat papan laminasi yang terbuat dari kayu kelapa dan kayu nangka berdasarkan jumlah lapisan (3 dan 5 lapis) dan bagian aksial batang (pangkal dan ujung) dengan ketebalan papan penyusun sebesar 1,5 cm. Hasil penelitian menunjukkan bahwa sifat mekanika (MoE dan MoR) dan keteguhan rekat 3 dan 5 lapis bagian pangkal batang lebih baik dibandingkan 3 dan 5 lapis bagian ujung. Karakteristik kayu laminasi menurun dari bagian pangkal batang kebagian ujung batang. Semakin banyak jumlah lapisan maka nilai MoE semakin menurun, sedangkan nilai MoR semakin tinggi.  Kekuatan perekat PVAc mampu menghasilkan keteguhan rekat yang baik dengan persentase kerusakan kayu yang rendah. Hasil penelitian ini menunjukkan bahwa arah aksial terbaik yang digunakan dalam pembuatan papan laminasi adalah bagian pangkal. Hasil penelitian papan laminasi dapat digunakan sebagai bahan kontruksi bangunan ringan, meubel dan pembangunan interior lainnya.Kata Kunci : Kayu Kelapa; Kayu Nangka; Papan Laminasi; Sifat Mekanika; Keteguhan Rekat

Abstract A comparison was made of Canadian sphagnum peat (SP) and Philippine coconut (Cocos nucifera L.) coir dust (CD) as growing media components for greenhouse production of Dracaena marginata Bak. and Spathiphyllum Schott ‘Petite’. Three soilless foliage plant growing mixes (Cornell, Hybrid, University of Florida #2 [UF-2]) were prepared using either SP or CD and pine bark (PB), vermiculite (V), and/or perlite (P) in the following ratios (% by vol): Cornell = 50 CD or SP:25 V:25 P, Hybrid = 40 CD or SP:30 V:30 PB, UF-2 = 50 CD or SP: 50 PB. Dracaena root growth was not affected by treatments but there were significant mix × media component interactions that affected plant top growth parameters. In general, the growth and quality of D. marginata were reduced by using CD in Cornell, had no effect in Hybrid, and increased in UF-2. S. ‘Petite’ grew equally well in all growing mixes regardless of whether CD or SP was used; however, plants grew more in Cornell and Hybrid than in UF-2. S. ‘Petite’ roots, which were infested with Cylindrocladium spathiphylli, had higher grades when grown in CD than when the media contained SP.
