Published: March 2018

In learning process must be found the student’s learning difficulties. The difficulties blocked students in learning process caused by several internal factors(talent, motive, intelligence, motivation) and external factors (family, teachers, peers). The student difficulty in learning general is caused by the lack of understanding of mathematical concepts. Skemp states that there are two types of mathematical concepts understanding, namely instrumental understanding and relational understanding. The purpose of research in this article is to describe the students' difficulties to solve the problem in a quadrilateral topic based on Skemp's Understanding theory. Skemp’s Understanding theory indicators include : students ability to classify objects based on requirements that can build this concept, students ability to apply this concept with algorithm , students ability to giving examples of a concept, students ability to present the concept in mathematics representation, students ability to relating various mathematical concepts, and the ability to develop the necessary terms and conditions is quite a concept. This research was designed in qualitative research. The data was collected by test and interview. The results show that the most difficult is about the students ability to relating various mathematical concepts.

Authors: Asih Diah Reni , Harimurti Sri , Wihandoyo Wihandoyo
Published: March 2018

This study was conducted to assess the effects of the 12 and 24 hours blue lighting on the performance of broiler chickens. This study used 2,700 broiler chickens that were divided into three treatments which are: control lighting (K) with conventional light used by farmers, 12-hours blue lighting (B12), and 24-hours  blue lighting (B24). Each treatment was repeated three times and consisted of 300 broiler chickens each. The parameters observed were feeding behaviour including the feeding duration, feeding frequency, and broiler chickens performance. The results showed that broilers treated with the B24 and B12 lighting have longer feeding duration (P<0.05), lower feeding frequency (P<0.05), higher body weight gained (P<0.05), and lower feed conversion (P<0.05) when compared to those of chickens with K lighting. The conclusion of this study showed that continuous 24-hours blue lighting (B24) caused longer feeding duration  and lower feeding frequency and the treatment of B24 and B12 lighting gave better benefits than control lighting.

Authors: Agistiana Seruni , Setiyaningsih Surachmi , Indrawati Agustin
Published: March 2018

The aim of this research was to evaluate the detection and differentiation of C. fetus subspecies through multiplex PCR (mPCR) method from the bovine preputial wash. The evaluation was done by comparing 2 extraction methods, which was by commercial kit extraction and boiling method, and also by measuring the effect of Transport Enrichment Media (TEM) addition as bacterial enrichment. Spiked bovine preputial washes with 2 extraction methods (commercial kit and boiling), with and without TEM addition were used as a sample. The results showed that the highest sensitivity/specificity was by boiling extraction without TEM addition, which reached 83.3%/100% for all or grouped sample. The results also supported by Poisson regression analysis which showed the comparison between sample with and without TEM addition which had 1.3 Incidence Rate Ratio (IRR). The obtained IRR score indicated that sample without TEM addition had 30% better result compared to the sample with TEM addition. Furthermore, a comparison between commercial kit and boiling extraction showed no significant difference (1.029 IRR). The research concluded that boiling extraction without TEM addition is the most accurate, fast and economical extraction method regarding its high sensitivity and specificity value, with less than 24 hours testing time and without any commercial kit requirements. However, a validation and verification with field sample were still needed before applied in the laboratory.

Authors: Zakiah NFN
Published: March 2018

Poverty is closely related to food security because poor people have limited consumption choice including that of food. This study aims to examine poverty line and correlation between poverty and food security in Aceh Province.  This study utilized a panel data from 23 regencies/municipalities in Aceh Province during the period of 2007-2013. To measure poverty line, approaches taken were minimum physical need based on minimum expenditure level of rice consumption and food security based on energy consumption. Data were analyzed using a 2SLS method. The result shows that the regions with low poverty line have lower energy consumption compared to those with higher poverty line. Banda Aceh has the highest poverty line and energy consumption level. On the other hand, North Aceh, Southeast Aceh, Bener Meriah Regencies, and Subulussalam Municipality are the regions areas with lowest poverty lines and energy consumption levels. To improve food security, some measures to take are food availability assurance, farmers’ empowerment, agricultural inputs subsidy provision, infrastructure construction, paddy field leveling-up, agricultural extension improvement, innovation invention, and food warehouse establishment.

 

Abstrak

Kemiskinan erat kaitannya dengan ketahanan pangan karena kemiskinan menyebabkan keterbatasan untuk mengonsumsi pangan. Penelitian ini bertujuan untuk melihat garis kemiskinan dan keterkaitan antara kemiskinan dan ketahanan pangan di Provinsi Aceh. Penelitian ini menggunakan data panel 23 kabupaten yang ada di Provinsi Aceh pada periode 2007–2013. Garis kemiskinan dianalisis menggunakan tingkat pengeluaran minimum dengan pendekatan kebutuhan fisik minimum, yaitu konsumsi beras (subsistence level), sedangkan ketahanan pangan dianalisis dengan pendekatan konsumsi energi. Penelitian ini menggunakan model ekonometrika dengan dua persamaan yang pendugaannya menggunakan metode 2SLS. Hasil analisis menunjukkan bahwa secara umum daerah dengan garis kemiskinan rendah mempunyai konsumsi energi lebih rendah dibandingkan daerah dengan daerah dengan garis kemiskinan lebih tinggi. Banda Aceh mempunyai garis kemiskinan dan konsumsi energi paling tinggi, sementara Aceh Utara, Aceh Tenggara, Bener Meriah, dan Subulussalam merupakan daerah dengan garis kemiskinan dan konsumsi energi paling rendah. Upaya peningkatan ketahanan pangan dapat ditempuh mulai dari tingkat ketersediaan pangan, yaitu dengan memberdayakan petani baik sebagai produsen maupun konsumen, melalui subsidi input, peningkatan infrastruktur, pencetakan lahan sawah baru, perbaikan sistem dan sumber daya penyuluh/pendamping, kerja sama dengan perguruan tinggi dalam menghasilkan inovasi, dan menghidupkan kembali lumbung pangan di setiap rumah tangga.

Published: March 2018

East Kalimantan is one of production center for white blackpepper, known as Samarinda White Pepper products. The variety developed in East Kalimantan is a local blackpepper variety that is not yet known for its characteristics. The research was conducted to observe the production and quality of local blackpepper in East Kalimantan, specifically in Kutai Kartanegara Regency which is the widest blackpepper development area in East Kalimantan. The observation was conducted for two years, at three locations of high yielding block (BPT) in Loa Janan and one non-BPT location in Muara Badak, as a local origin of local East Kalimantan blackpepper which is currently developing in Loa Janan. The environmental design used was a Randomized Block Design, with four trial sites, repeated six times in each location, using the same variety (local blackpepper). The average production for two years of observation reached 2.94 kg fresh berries/tree equivalent to 2.17 tons of white pepper/ha/year. However, the average of spikes containing pepper berries reached only 61.3% per panicle. Therefore, it requires intensive fertilization with appropriate dosage and fertilizer type to increase the expression of its potential genetic because local pepper of East Kalimantan bears fruit continuously throughout the year. Result of yield-quality analysis showed that local white pepper of East Kalimantan contained 11.23% oleoresin and 3.82% piperin, higher than Petaling 1 (10.66% and 3.03%, respectively). The superiority characteristics of local blackpepper of East Kalimantan is a distinctive aroma and spicy flavor, due to the high content of piperin and oleoresin.

English
Promoting agricultural sector is important for improving Indonesia economic performance. The objectives of the research are to determine the effects of levels and shocks of agricultural export, import, and investment on the growth (GDP) of the Indonesian agriculture sector. The research was conducted using quarterly time series data from 2000–2015. Vector Auto Regression analysis method was applied in this study. The causality analysis shows that the agricultural export, import, and investment levels do not significantly affect the agricultural GDP growth, but the agricultural GDP growth does significantly affect the level of agricultural export, import, and investment. The impulse response analysis shows that the investment response to GDP growth shocks is higher than that of export and import responses. The variance of decomposition analysis shows that the contribution of exports to agricultural GDP growth are larger than the contribution of imports and investments. This study concludes that the absolute value of the agricultural sector export, import, and investment do not affect the sector GDP growth rate, but the agricultural sector GDP growth rate affect the absolute value of the sector export, import, and investment in Indonesia.

Authors: Sharma Monica , Nuhmani Shibili , Wardhan Deepti , Muaidi Qassim I
Published: March 2018

OBJECTIVE: This study compared lower limb muscle flexibility between amateur and trained female Bharatanatyam dancers and nondancers. METHODS: Subjects consisted of 105 healthy female volunteers, with 70 female Bharatanatyam dancers (35 trained, 35 amateurs) and 35 controls, with a
mean (±SD) age of 16.2±1.04 yrs, height 155.05±4.30 cm, and weight 54.54±2.77 kg. Participants were assessed for range of motion (ROM) in hip flexion, hip extension, hip abduction and adduction, hip external rotation, hip internal rotation, knee flexion, knee extension,
ankle dorsiflexion (DF), and ankle plantar flexion (PF) by using a standardized goniometer. To assess for significant difference between groups, one-way ANOVA was applied, and multiple comparisons were made using Bonferroni correction. RESULTS: Trained dancers had a significantly greater hip
flexion, extension, abduction, and external rotation ROM than amateurs and nondancers (p<0.05). Also, internal rotation and adduction were markedly less in trained dancers (p<0.05). Knee flexion, extension, and ankle DF were higher and ankle PF ROM was lesser in trained dancers. However,
not much variation was found in ankle DF and PF between amateur dancers and nondancers (p>0.05). CONCLUSION: Results showed that there are significant differences in lower limb muscle flexibility between trained and amateur Bharatanatyam dancers and nondancers. These differences may be
due to individual dance postures such as araimandi and muzhumandi.
Effects of Aging on Musical Performance in Professional Orchestral Musicians
Authors: Kenny Dianna T , Driscoll Tim , Ackermann Bronwen J
Published: March 2018

BACKGROUND: The physical and psychological demands of playing a musical instrument are likely to be affected by age-related decline in function, including physical, cognitive, psychological, and organ-related changes. However, the complex neurophysiological demands of playing a musical
instrument may delay many normal aging-related changes. AIM: This study compared professional classical musicians of different ages, using a range of physical and psychological measures, to discover how increasing age might affect work performance and to identify possible risk and protective
factors for physical and psychological health as the musicians age. SUBJECTS: 377 professional orchestral musicians from eight Australian orchestras (70% response rate), ages 18 to 68 yrs (mean 42.1). Multiple standardized physical and psychological tools were used to evaluate the impact of
age on a range of physical and mental health variables. RESULTS: Age was not statistically associated with frequency or severity of performance-related musculoskeletal disorders, ratings of perceived exertion, QuickDASH scores, use of beta-blockers, workplace satisfaction, and most psychological
tests. Differences were observed on SPIN (social anxiety) scores, with lowest scores in the oldest age group (10.66 in 55+ yrs vs 17.83 in 18-30 yrs, p=0.016). Older musicians had higher BMIs and fewer practice sessions per day than younger musicians and also were more likely to consume alcohol
on 5+ days/wk (44% vs 9%, p=0.003). CONCLUSION: Advancing age does not appear to exert undue negative impacts on physical and psychological health or performance capacity of professional orchestral musicians. However, dwindling numbers in the older age groups may suggest a "survivor"
effect, whereby those who develop significant age-related decrements may cease professional performance at earlier ages. Longitudinal studies on the professional trajectories of professional orchestral musicians are needed to explore this question further.

Authors: Clement Bellido Juan
Published: March 2018

The rise of optical fiber communications in the last three decades has been accompanied with the development of a large number of sensors based on this technology, overcoming in many aspects the characteris-tics of the current electrical sensing systems. Optical fiber sensors pro-vide a wealth of applications in a variety of fields, ranging from struc-tural health monitoring to detection of chemical species. In this article, after enumerating the principal benefits of optical fiber sensors, it is presented a review about the two key aspects of opti-cal fiber sensing system, namely the sensing devices and their interroga-tion methods, respectively. In both parts, the main devices and methods have been included. In the devices section, examples of single-point, multi-point and dis-tributed sensing elements are given. In the same way, a number of inter-rogation methods are briefly described, including standard spectral analysis, interferometry, and time-domain and frequency-domain meth-ods for both point and distributed optical fiber sensing systems.

El terremoto 19S en Morelos: la experiencia operativa del INEEL en la evaluación del riesgo estructural
Authors: García-Carrera Jesús Salvador , Mena-Hernández Ulises , Bermúdez-Alarcón Francisco Javier
Published: March 2018

El sismo del 19 de septiembre de 2017 en México causó daños catastróficos en el estado de Morelos que afectaron a más de 23 000 inmuebles en prácticamente todos losmunicipios del estado. Después de un sismo, resultan de gran importancia las acciones de emergencia existentes en la región para dar apoyo a la sociedad, tanto en el rescate de personas atrapadas como en la evaluación de la  ondición estructural que presentan los inmuebles, y de esta manera, mitigar sus efectos. Las acciones de emergencia requieren de planeación, organización, recursos económicos y materiales y, sobre todo, de trabajo en equipo. Desafortunadamente muchas sociedades no están preparadas para contener grandes desastres, por lo que puede resultar muy difícil hacer frente a una gran emergencia sin las condiciones adecuadas. Durante la emergencia del 19 de septiembre se vivió una situación jamás esperada en el estado de Morelos por los daños provocados por el sismo de magnitud 7.1, con epicentro a menos de 75 km de distancia, que puso a prueba al sistema de emergencia del estado. De manera particular, investigadores del Instituto Nacional de Electricidad y Energías Limpias (INEEL) iniciaron acciones de inspección en los inmuebles de su propio instituto, y posteriormente se pusieron a las órdenes de Protección Civil del Estado de Morelos para realizar inspecciones post-sísmicas de los inmuebles de gobierno, escuelas y, en general, de las viviendas de Morelos. La tarea principal del apoyo del INEEL consistió en dictaminar si los inmuebles debían continuar operando o ser habitables, si debían ser desalojados para hacer una revisión detallada o incluso si debían ser demolidos debido al alto riesgo de colapso que presentaban. El apoyo proporcionado por el INEEL no sólo se concentró en la evaluación post-sísmica de los inmuebles, sino que ha sido el inicio de una mayor colaboración con las autoridades del Estado, que resultará en el mejoramiento de los planes de emergencia y, sobre todo, en la actualización de las normas de diseño.

Similarity of the Effect of Different Dissolved Gases on Heavy-Oil Viscosity
Authors: Freitag Norman P.
Published: March 2018

An analysis of viscosity data for mixtures of different gases dissolved in three different heavy oils and bitumens revealed that, at the same molar concentrations and at the same pressure, each of these gases reduced the oil-phase viscosity by almost the same amount. Because the gases that were examined included both hydrocarbons and nonhydrocarbons, it was concluded that this behavior could be generalized to include most of the gases encountered in, or injected into, heavy-oil and bitumen reservoirs.

This principle was discovered in the new results of a study on two heavy oils. These oils were mixed with methane or carbon dioxide or propane to achieve vapor/liquid equilibrium at various pressures. When the measured oil-phase viscosities were adjusted to the same pressure without further change to their compositions, and were subsequently plotted against gas concentration in mole percentage, all the values fell on approximately the same curve. The same behavior was subsequently observed in gas/bitumen data that had been published previously by other authors.

Although it can be reasoned that the adjusted viscosities must begin to diverge at high concentrations when different gases are used, the differences were not experimentally discernable even at dissolved-gas concentrations as high as 60 mol%. The effect was the same when more than one dissolved gas was present.

The application of this uniformity principle is expected to make it easier to compare the costs of using different solvent gases to reduce the viscosity of heavy oils and bitumens during enhanced-oil-recovery (EOR) operations.
Cover Crop Mixtures Grown for Annual Forage in a Semi‐Arid Environment
Authors: Sanderson Matt , Johnson Holly , Hendrickson John
Published: March 2018

Core Ideas

Cover crop species combinations can affect productivity and weed invasion.

Mixtures with equal species proportions did not yield more forage or have less weeds.

Spring‐planted cover crops suppressed weeds regardless of mixture or monoculture.

Hot dry weather can reduce productivity of late‐summer planted cover crop mixtures.

Use of cover crop mixtures in the dry short‐season environment of the northern Great Plains requires knowledge of how species combinations affect productivity and weed invasion. We hypothesized that mixtures would be more productive and suppress weeds better than monocultures. Fifteen combinations of proso millet (Panicum milaceumL), triticale (Triticosecale rimpauiWittm.), red clover (Trifolium pratenseL.), and radish (Raphanus sativusL.) were sown in spring (July harvest) and late‐summer (October harvest) for 3 yr at Mandan, ND. Treatments included four monocultures, four mixtures dominated by one species, six mixtures dominated by pairs of species, and one equal mixture. On average, spring‐planted mixtures yielded 30 to 60% more forage (2400 kg dry matter ha−, 3 yr avg) than the average of spring‐planted monocultures (1720 kg ha−, 3‐yr avg.) when planted in spring. Mixtures, however, did not yield more forage than the most productive monoculture (triticale; 3165 kg ha−, 3 yr avg.). The late‐summer planted cover crops produced little forage (94–155 kg ha−) because of dry soil conditions and erratic rainfall. Mixtures with equal proportions of species did not yield more forage or have fewer weeds than other mixtures. Species mixtures affected nutritive value. Grass‐dominated mixtures had lower crude protein and greater fiber concentrations than radish‐dominated mixtures. Cover crop mixtures can yield more than monocultures when planted in spring in this short‐season environment; however, use of cover crop mixtures in late‐summer does not mitigate risk of poor establishment and low productivity because of hot dry weather.
Diverse Grain‐Filling Dynamics Affect Harvest Management of Forage Barley and Triticale Cultivars
Authors: Lyu D. , Doce R.R. , Juskiw P. , Zhou G. , Baron V. S.
Published: March 2018

Core Ideas

Decision‐making criteria are needed to optimize silage production in barley and triticale.

The critical factors, yield, forage quality, and dry matter interact in the grain‐filling period.

Optimization of factors is required and the indicator for harvest may differ between species.

Comparison on a growing degree day scale during grain filling provided an assessment of dynamics.

Triticale needed more degree days than barley to optimize yield and dry matter shown by dough stage.

Harvest time for small‐grain forage is impacted by changes in yield, dry matter concentration (DMC) and forage quality during grain‐filling. Little information exists for hulless and two‐rowed barley (Hordeum vulgare L.) and triticale (X Triticosecale Wittmack) grown in Alberta. Two barley and two triticale cultivars were grown at three planting dates and two locations over 2 yr at Lacombe, AB, Canada. Forage was harvested five times after boot stage at 7‐ and 10‐d intervals for barley and triticale, respectively. Relationships were developed by regressing variables with growing degree days (GDD) after the boot stage for triticale cultivars, combined, and each barley cultivar (‘Falcon’ and ‘Gadsby’). Comparisons were made at GDD positions. Triticale out‐yielded and dried slower than barley and had higher DMC for 560 GDD after the boot stage; Gadsby out‐yielded Falcon. The soft dough stage (DS 85) indicated optimum yield, 93% of relative dry matter yield (RDMY) at less than 400 g kg−1 DMC for barley and triticale, but occurred at 400 and 500 GDD after the boot stage, respectively. Triticale had lower in vitro true digestibility (IVTD) and higher fiber levels than barley at boot stage; but triticale IVTD decreased slower than barley and Falcon declined faster than Gadsby. Starch accumulated more rapidly for Gadsby than Falcon, while triticale increased slowly initially, then rapidly later in the grain filling period. Delaying harvest by 100 GDD for triticale compared to barley (both at DS 85) resulted in the higher triticale yield, while allowing more starch to accumulate.

Core Ideas

Foliar fertilizer treatments did not deplete soil nutrient levels after three years of applications.

Combining foliar and granular fertilizers resulted in the best turfgrass quality.

Biweekly application of foliar fertilizers resulted in higher turf quality than monthly granular fertilizer applications.

Research was conducted to determine the effects of foliar and granular fertilizers on creeping bentgrass [Agrostis stolonifera var. L. palustris (Huds.) Farw. ‘Penn A4’] quality and soil nutrient levels of two putting green rootzones. The hypothesis was foliar fertilizers would decrease soil nutrient levels and result in lower turfgrass quality over 3 yr compared to granular fertilizers. The fertilizer treatments were granular urea, methylene urea, and natural organic, foliar fertilizer at two rates, foliar‐granular combination, and an untreated control. The two rootzones were a United States Golf Association (USGA) guideline rootzone and a sandy clay loam (58% sand, 20.5% silt, and 21.5%) native soil. The urea, methylene urea, natural organic, and foliar‐granular treatments were applied at 0.5 lb N/1000 ft2/month from May through October. The foliar treatment was applied at two rates, 0.25 and 0.5 lb N/1000 ft2/month from May through October. Soil samples were collected from 2009 to 2011 and turfgrass quality was rated every 2 weeks. Turfgrass growing on native soil had consistently higher quality than turfgrass on the USGA rootzone and native soil had higher soil NO3–N, P, and K levels than the USGA rootzone. Neither the foliar, granular, or combination treatments decreased soil NO3–N, P, or K levels compared to initial soil test levels over 3 year of research. Every two weeks, applications of both the combination and foliar 2X treatments produced higher turfgrass quality than monthly methylene urea, urea, and organic treatments. Although the 0.25 lb N/1000 ft2/month foliar treatment had a lower N rate than all fertilizer treatments, it had acceptable quality throughout the research.
Nitrate Leaching in a Loamy Sand Soil Receiving Two Rates of Liquid Hog Manure and Fertilizer
Authors: Karimi Rezvan , Akinremi Wole
Published: March 2018

The effect of liquid hog manure (LHM) and commercial fertilizer on NO3−–N leaching was measured for 2 yr in a long‐term manure experiment on a loamy sand soil at Carberry, MB. The field experiment, sown to barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.), comprised six treatments including two rates of LHM (28, 084 and 56,168 L ha−1 [2500 and 5000 gal acre−1, abbreviated LHM‐2500 and LHM‐5000, respectively]), two rates of fertilizer (abbreviated F‐2500 and F‐5000) corresponding approximately to available N in LHM‐2500 and LHM‐5000, compost (abbreviated Com‐2500) supplemented with urea to approximate available N in LHM‐2500, and an unamended control. In 2010, apparent losses amounted to 79 (112 kg ha−1), 55 (40 kg ha−1), 27 (19 kg ha−1), 24 (16 kg ha−1), and 6% (8 kg ha−1) of applied available N in F‐5000, Com‐2500, F‐2500, LHM‐2500, and LHM‐5000, respectively. In 2011, losses were higher in the F‐5000 (80%, 63.6 kg ha−1) and F‐2500 (79%, 31.5 kg ha−1) treatments than in LHM‐5000 (40%, 32 kg ha−1) and LHM‐2500 (9%, 3.5 kg ha−1). Treatments that received fertilizer lost more than half of the added N by leaching. The lack of yield difference between LHM‐2500 and LHM‐5000 suggested that application of LHM‐2500 was environmentally sound for the coarse sandy soil of the Carberry site. These findings demonstrate the potential for minimizing N leaching through judicious rates of LHM and fertilizer application.

Core Ideas

Fertilizer treatments had greater N loss than liquid hog manure (32 vs. 3.5 kg ha−1).

Treatments that received fertilizer lost more than half of the added N by leaching.

The lower rate of LHM led to the same crop yield with lower environmental impact.

Published: March 2018

Emotional advertising on the Internet such as websites and social media can be highly beneficial for Small Medium Enterprises (SMEs). However, not all ofSMEs have a website that meets all of the principles of website design which are persuasive. Moreover, the color is rarely considered in making websites to raise the emotional bonding between the products and audiences of SMEs. Literature review, observation to four websites as case studies, and questionnaires distributed to respondents randomly were performed. This research aimedto evaluate the extent to which SMEs from Bandung exploited the use of color as an element in the web User Interface (UI) design and to analyze whether thecolor could provide emotional bonding, so the visitors were interested in purchase or trial of the product. This research finds that participants responses to color are various in different demographic factors. Zananachips.com is considered to successfully utilize the color in the web UI design to build its brand identity, raise interest in the trial of the product, and engage the consumer with the website. This research is expected to be a reference forSMEs in creating emotion, motivation, and persuasion through website design.

Published: March 2018

Boolean Retrieval (BR) and Vector Space Model (VSM) are very popular methods in information retrieval for creating an inverted index and querying terms. BR method searches the exact results of the textual information retrieval without ranking the results. VSM method searches and ranks the results. This study empirically compares the two methods. The research utilizes a sample of the corpus data obtained from Reuters. The experimental results show that the required times to produce an inverted index by the two methods are nearly the same. However, a difference exists on the querying index. The results also show that the numberof generated indexes, the sizes of the generated files, and the duration of reading and searching an index are proportional with the file number in the corpus and thefile size.

This paper implements static hand gesture recognition in recognizing the alphabetical sign from “A” to “Z”, number from “0” to “9”, and additional punctuation mark such as “Period”, “Question Mark”, and “Space” in Sistem Isyarat Bahasa Indonesia (SIBI). Hand gestures are obtained by evaluating the contourrepresentation from image segmentation of the glove wore by user. Then, it is classified using Artificial Neural Network (ANN) based on the training model previously built from 100 images for each gesture. The accuracy rate of hand gesture translation is calculated to be 90%. Moreover, speech translation recognizes NATO phonetic letter as the speech input for translation.
