Coconut is a multipurpose tree for people in the tropics. Almost all parts can be used such as leaves, fruit, stems, and roots. Besides having many benefits of coconut, it also produces waste from its fruit, namely coconut fiber. Coconut coir has a very high tannin content. In general, tannin compounds can be indicated as anti-inflammatory, and anti-bacterial. The purpose of this study was to formulate the anti-acne mask from coconut coir extract and to test its physical properties. This study uses an experimental research method, in which three mask formulas are made with variations in the concentration of active substances and polyvinyl alcohol (PVA). In this study the active substance used was coconut coir extract. The formulas used are formulas A, B, and C with the concentration of active substances successively as follows: 1%, 2%, 4%. The results of research that have been carried out that the mask formula that has the best physical properties is formula B, because it fulfills the physical properties provisions of the peel off face mask including organoleptic, homogeneity, pH, dispersal power, and drying time.

The objective of the study was to (1) evaluate land suitability for coconut (cocos nucifera L.) production in relation to soil physical properties, (2) identify the soil physical constraints and (3) study their effect on the morphological adaptation of coconut roots. Soil physical properties were found to be significantly related to coconut yield (R2=81.37; p<0.01). Multiple regression with cluster analysis of soil physical properties vs coconut yield enabled classification of soil series into three major groups namely (a) highly  (b) moderately and (c) less productive series. It was observed that the high soil compaction which limited the available water and aeration capacity of soils resulted in retardation of the activity of coconut roots. Water stress due to soil compaction was found to induce production of more inactive roots by suberization and dehydration processes. Scanning electron microscopic image showed that soil compaction and water stress, reduced the cell volume per unit area  of the absorption zone and the number of pores in respiratory organs of  coconut roots resulting in retardation of water and nutrient absorption, and air exchange processes. This in turn malfunctions of absorption cells and respiratory organs of roots resulted in retardation of growth of coconut seedlings. The practical importance of these findings in formulation of land suitability maps for coconuts is discussed.

Damaged skin due to free radicals from ultraviolet radiation can be prevented using antioxidants. Red dragon fruit (Hylocereus polyrhizus) containing antioxidants can be made into a peel off gel face mask using gelatin as a gelling agent to be applied easily to the skin. The purpose of this study is to determine the effect of various gelatin concentrations on the physical properties and antioxidant activity of peel off gels containing red dragon fruit juice. The peel off gels face mask were made using various gelatin concentration i.e 7.5% w/w (F1); 10% w/w (F2); and 12.5% w/w and containing 10% w/w red dragon fruit. The peel off gels then evaluated for physical properties and antioxidant activity using DPPH. The result showed that the increasing of the gelatin concentration would increase the drying time and adhesive ability of the peel off gels. The escalation of gelatin concentration from 7.5% w/w (F1) to 10% w/w (F2) did not affect the spreading ability of the peel off gel. However, the spreading ability of the peel off gel decreased with the increasing concentration of gelatin from 10% w/w (F2) to 12.5% w/w (F3). The antioxidant test of peel off gel had an average percentage of inhibition of 9.101% (F1); 12.469% (F2); and 15.109% (F3). Based on the results of physical properties and antioxidant activity showed that formula 2 was recomended.

The coconut is known as Kalpa Vriksa to the world for being its multi faceted uses, which provide livelihood security to millions of people. Every part of it useful to humans in one of the other ways. The coconut palm is grown in more than 93 countries of the tropics. Its botanical name is Cocos-Nucifera L. and belongs to the aracaceae (Palm) family. The climbing methods of coconuts like manual, mechanical and climbing by Tractor Operated Hydraulic Elevator (TOME) were studied. The stability, safety, harvesting efficiency, drudgery of coconut harvesting is reduced by Tractor Mounted and Self Propelled Coconut Climber (TMSPCC) developed by considering the drawbacks of the above methods. The testing of developed TMSPCC was carried out at a Coconut Research Station, Bhyte Ratnagiri, India. To assess the physiological cost and the drudgery involved in the traditional method of tree climbing operation. The digital polar hart rate meter RS400TM having infrared connectivity sensor was used for recording the heart rates. The technical assessments included the use of biomechanical models, ODR, BPDS. The ergonomical evaluation of TMSPCC was carried out for testing feasibility, ease of operation; workers jeopardize safety health and efficiency for coconut harvesting. Ergonomically operational safe and controlled heart rates are recorded. The fourteen to seventeen number of coconut orchards were harvested in one hour by using TMSPCC. The tractor mounted and self propelled coconut climber founds suitable for harvesting 100 to 120 coconut trees in a day. The net coconut harvesting by using TMSPCC are 4000 coconuts/day. Also TMSPCC is safe, less hazardous and economical as compared to manual climbing coconut harvesting and climbing by the existing tractor mounted hydraulic elevator.

Introduction: Methicillin-Resistant Staphylococcus aureus (MRSA) bacterial infections may cause poor manifestations and even increase patients’ morbidity and mortality. The use of antibiotics in the management of infections remains the main therapy. However, ever-increasing antibacterial resistance has prompted researchers to find the solution. This study aimed to determine the effect of a combination of red coconut coir (Cocos nucifera L. var rubescens) in various concentrations and linezolid 10 µ/ml on the growth of MRSA bacteria in vitro.Methods: The antibacterial activity test method was well-diffusion test. Bacteria was plated in mueller hinton agar for 24 hours at 37oC. The treatment groups were red coconut coir extract and its combination with linezolid 10 µg/ml.  The well-diffusion test results were statistically analyzed with the One-Way ANOVA and Tukey HSD post-hoc tests.Results: Mean inhibitory zone diameter formed in the C. nucifera L. var rubescens extract test in various concentrations was 12.5 ± 0.36 - 16.2 ± 0.79 mm, while its combination with 10 µg/ml linezolid produced mean inhibitory zone of 15.1 ± 1.31-18.4 ± 0.46 mm. There was a significant difference between groups (p<0.05).Conclusion: Increasing concentration of C. nucifera L. var rubescens extract was in line with the increase of mean diameter of the inhibitory zone. Extract and antibiotic combination tests showed higher mean diameter zones than the single test of materials. The combination of extract and linezolid has the potential to synergistically prevent antibacterial resistance.

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.
