Abstract

Java contributes 63.7% of national sugar production, in which 55.6% is produced by the farmer from 312,973 ha of sugarcane area (65.6% of Indonesia’s cane crop area). Farm labor in Java was very limited in the past two decades, so was needed mechanization. Howeveer, the size of agricultural machines were not accordance with the size of land, the limited of spares, and was not optimally managed. This research aimed to calculate operational cost of farm machinery (hand tractor) on the cane cultivation activities up to 6-month cane growth period. This study was carried out at Comal, Center of Java at alluvial land 8 mdpl and at Pasuruan, East Java at alluvial 10 mdpl. From each location, 2 plots of 0.1 ha were observed. The treatments were manual and machine cultivation with 3 replications. The observed agrotechnical parameters were the bud emergence, number of stalk, clump, stalk height and diameter, and operational cost of using machinery. The agrotechnical result using t-test (95% confidence rate) showed no significance among treatments. Other results revealed that using machinery for fertilizing, soil heaping up, and soil moving (gulud) in Pasuruan can substitute manual daily worker (HOK) for 6 HOK, 12 HOK and 20 HOK, respectively, using tractor by 7 hours/day. Meanwhile in Comal, using machinery for fertilizing, soil heaping up, and soil hilling up (gulud) can substitute manual daily worker (HOK) for 9 HOK, 16 HOK, and 20 HOK, respectively. The cost analysis indicated the 35.54% reduction of using machinery compared to the manual expense. This study revealed that the machinery could substitute the manual worker for cane cultivation.

Abstract

Application of organic fertilizers in the production of plants is aimed to eliminate or substantially reduce the use of chemical inputs and improve the growth and quality of plants. For instance, in present study, the effect of vermicompost and spent mushroom compost application on nutritional status and essential oil components of summer Savory (Saturejahortensis L.) was investigated. This experiment was conducted in the research greenhouse of Faculty of Agriculture at Mohaghegh Ardabili University using a layout of completely randomized design with five replications on Savory in 2014. Experimental treatments included different substrates that contained vermicompost, washed and unwashed spent mushroom compost in five levels (10, 20, 30, 40 and 50 Percent v/v). After flowering, the plants were harvested and parameters such as leaf area, leaf and plant dry weight, chlorophyll index of leaf and N, P, K, and Ca content and essential oil component of plants were measured. The results showed that the effect of organic substrates on macronutrient content and savory’s growth parameters was significant. The highest Nitrogen content (6.3%) and Phosphorus (0.98%) in savory shoot was obtained in a substrate supplemented with 40% vermicompost. Plants grown in the media containing 30% of vermicompost and 50% of washed spent mushroom compost (SMC) have higher potassium (3.19%) and calcium (2.48%) content, respectively. The lowest nitrogen, phosphorus and potassium content in the aerial part was obtained in the control treatment. Moreover, application of organic fertilizers significantly affected on savory’s essential oil percentage and compounds composition. The highest and lowest essential oil contents were obtained in plants in substrates containing 30 % of vermicompost and unwashed spent mushroom compost respectively. The main components of essential oil were carvacrol and gamma-trepenine. The highest level of carvacrol (62.10) and gamma-trepenine (32.05) were obtained in plants in substrates containing 40 and 20% of washed spent mushroom respectively.

Abstract

In order to determine soil characteristics and above-ground and below-ground carbon sequestration potential of wheat, a systematic random sampling method was employed to select 5 samples from 50 fields situated in Khorasan-Razavi Province, Iran during 2015. The experimental design was a completely randomized design with three replications. The ash method was used to determine the carbon sequestration conversion coefficients in spikes, stems, leaves and roots. Then, greenhouse gases (such as CO2, N2O and CH4) emission were calculated using emission coefficients. The average organic carbon, total nitrogen, available phosphorus, available potassium, soil bulk density, pH and electrical conductivity were found to be 0.98%, 0.02%, 27.07 ppm, 341.32 ppm, 1.37 g.cm-3, 7.81 and 1.42 dS.m-1, respectively. The maximum (52.0%) and minimum (31.99%) conversion coefficients were related to spikes (seeds included) and roots, respectively. In addition, the total carbon sequestration was 8.25 t.ha-1 so that the maximum (4.28 t.ha-1) and minimum (0.35 t.ha-1) values were found in stems and roots, respectively. The total global warming potential (GWP) of wheat was recorded as 2377.86 kg CO2 –equiv. per ton of seed. The first contributing factor was nitrogen fertilizers, accounting for 1331.30 kg CO2 –equiv. per ton of seed.

Abstract

The increasing human population and income per capita in Indonesia have many impacts to the demand of food, not only staple food but also the secondary food too, including meat and beef demand. Based on data from Central Statistics Bureau of 1995–2016, beef demand in Indonesia has been increasing. This condition must be anticipated by preparing the supply, especially the availability of beef in Daerah Istimewa Yogyakarta province. In Yogyakarta city, one of the regencies of DIY, the demand rate grows by 3.2%/year, higher than the supply growth rate by 2.08 %/year.  This gap needs to be thought through the case of scarcity of beef on the market. This study aimed to identify the potential of supply in five parameters i.e.: beef population, the availability of semen for artificial insemination (IB), the availability of livestock feed plants (HMT), the number of cows that enter DIY, and the number of cows that exit from DIY. A model Spatial Geographic Information Systems (SGIS) has been used in this study. The study revealed the most potential area for the development of beef agribusiness, based on the availability side, was Gunung Kidul Regency, and the less potential was Yogyakarta municipality.

Abstract

Tamarillo is an underutilized fruit in Indonesia, despite the fact that it contains two pigments (anthocyanin and carotenoid) with different properties (polar and non polar). Besides, there is a scarce information about extraction of anthocyanin and carotenoid of Tamarillo using sonication extraction. This study was aimed to investigate the comparison of extraction methods of sonication with maceration on antioxidant potency of anthocyanin and carotenoid of Tamarillo. Two pigmen types (anthocyanin and carotenoid) were extracted using two different methods (sonication and maceration). The parameters of analysis were yield, antioxidant activity (DPPH) with IC50, Ferric Reducing Antioxidant Power (FRAP), anthocyanin total, carotenoid total, phenolic total and scanning electron microscope of cover cell of material. The antioxidant potencies for both anthocyanin and carotenoid by sonication method were higher than those of obtained by maceration method. The results showed that both sonication and maceration were suitable for extraction of anthocyanin and carotenoid from Tamarillo.

Abstract

This study was aimed to examine effect of inoculation with Arbuscular Mycorrhizal Fungi (AMF) and intercropping with several mungbean varieties on yield components of red rice grown under aerobic irrigation technique. The experiment was carried out in a pot in the plastic house from June to September 2017. The experiment was designed using Completely Randomized Design with two treatment factors arranged factorially, i.e. AMF inoculation (M0= without, or M1= with AMF inoculation) and mungbean varieties (V) grown together with red rice plant (V1= Kenari, V2= Vima-1, V3= Vima-3, V4= Merak, and V5= No. 129 ). Each treatment combination was made in triplicate. The results indicated that inoculation had a significant effect in increasing filled panicle number, number of filled grains, and dry grain yield per pot, while decreasing percentage number of unfilled grains. For the rice plants incoluated with AMF, intercropping with mungbean of Kenari and Merak varieties produced similar or higher number of filled panicles compared to those without intercropping. In contrast, for the rice plant without inoculation with AMF, intercropping resulted in lower amount of filled panicles than those without intercropping.

Abstract

β-Carotene exhibits a wide range of health benefits, but its application in food formulation is very limited because of its instability and susceptibility to degradation. The stability of β-carotene can be improved by incorporation into an oil-in-water (o/w) emulsions. The objective of this research was to characterize β-carotene loaded nanoemulsions prepared with spontaneous emulsification method using ternary food-grade surfactants (Tween 80, Span 40, Span 80) and palm oil or VCO (virgin coconut oil) as oil phase with the surfactant-oil ratio of 4. The physicochemical stability of β-carotene loaded nanoemulsions during simulated digestions, which consist of the mouth, stomach, and intestine phases, was also evaluated using in-vitro digestion model. The results showed that β-carotene loaded nanoemulsions, prepared either using VCO or palm oil as the oil phase, had neutral pH (6.8±0.1), mean particle diameter of 129 -159 nm, showed monomodal particle size distribution with low polydispersity index (PdI) values  (0.214 - 0.266), and were not significantly different in zeta potential values ([-6,59]–[-8,9]). The β-carotene loaded nanoemulsions with VCO as the oil phase had a smaller mean particle diameter than that of palm oil. The physical stability of the β-carotene loaded nanoemulsions against digestive simulation in the mouth, stomach or intestine phases was not influenced by the oil phase type.  Both nanoemulsions were stable against simulated digestion in the mouth and stomach phases. After passing through the intestinal phase, the mean particle diameter increased and the particle size distribution changed from monomodal to bimodal. The β-carotene retention after passing through the mouth, stomach and intestinal phases of the β-carotene loaded nanoemulsion prepared using VCO were not significantly different from the palm oil. ABSTRAKβ-Karoten mempunyai berbagai manfaat kesehatan, namun aplikasinya dalam formulasi pangan sangat terbatas karena tidak stabil dan mudah mengalami degradasi. Stabilitas β-karoten dapat ditingkatkan dengan menggabungkannya dalam sistem penghantaran berbasis emulsi minyak dalam air (o/w). Penelitian ini bertujuan untuk melakukan karakterisasi nanoemulsi β-karoten yang dibuat dengan metode emulsifikasi spontan menggunakan kombinasi tiga surfaktan food grade (Tween 80, Span 40, Span 80), minyak sawit maupun VCO (virgin coconut oil) sebagai fase minyak dengan rasio surfaktan-fase minyak 4.. Penelitian ini juga mengkaji stabilitas fisikokimiawi nanoemulsi β-karoten selama pencernaan di mulut, lambung dan usus dengan menggunakan model digesti in vitro. Hasil penelitian memperlihatkan bahwa nanoemulsi β-karoten yang dibuat dengan fase minyak VCO maupun minyak sawit memiliki pH netral (6,8±0,1), rerata diameter partikel 129–159 nm, distribusi ukuran partikel monomodal dengan nilai indeks polidispersitas (polydispersity index, PdI) rendah (0,214–0,266) dan zeta potensial yang tidak berbeda nyata ([-6,59]–[-8,9]). Nanoemulsi β-karoten dengan fase minyak VCO memiliki rerata diameter partikel yang lebih kecil dibanding minyak sawit sebagai fase minyak. Jenis fase minyak tidak berpengaruh terhadap stabilitas fisik nanoemulsi β-karoten selama simulasi pencernaan di mulut, lambung maupun usus. Nanoemulsi β-karoten dengan fase minyak VCO maupun minyak sawit stabil terhadap pencernaan di mulut maupun lambung. Setelah melewati fase usus, terjadi peningkatan diameter partikel rerata dan perubahan distribusi ukuran partikel dari monomodal menjadi bimodal. Retensi β-karoten dalam nanoemulsi VCO setelah melewati simulasi pencernaan mulut, lambung dilanjutkan fase usus tidak berbeda nyata dengan retensi β-karoten dalam nanoemulsi minyak sawit.

Abstract

Cultivation crop is influenced by soil, water, climate, and crop properties. Air temperature is one of climate parameters which is considered for plant growing. Soil moisture represents soil and water factors and it generally plays an important role in crop cultivation. A crop requires soil moisture and air temperature for an optimum growth. a control system is proposed to create an optimum air temperature and soil moisture to support plant growth. The aim of this study was to design a precision measurement instrument, a control system that is able to control microclimate (air temperature and soil moisture) for optimal growth of chili (Capsicum annuum L.) crops. A design of environmental control was applied by using sensors for air temperature and soil moisture. Microcontrollers were connected to sensors with the water pump actuator and the irrigation pump through a relay module and a TIP122 transistor. The accuracy of DHT 22 temperature sensors and soil moisture sensors were calculated based on the approximate coefficient of determination, and the total errors of each sensor. The actuator performance in this design included the response rates and the duration of the working time. The performance tests were conducted 3 times without using chili plants. The coefficient of determination (R²) of temperature sensor 1, temperature sensor 2 and temperature sensor 3 were 0.999, 0.999, and 0.999, respectively. The total errors of the three sensors were -0.071 ºC, -0.085 ºC, and 0.014ºC, respectively. The coefficient of determination (R ²) of the soil moisture sensor 1, the soil moisture sensor 2, and the soil moisture sensor were 0.888, 0.8401, and 0.8963, respectively. The mean total errors for these three types of ranging sensors were -0.2204%, -0.0952% and -2.8049%, respectively.

Abstract

Color had a correlation with physical appearance, nutritional and chemical content as well as sensory properties which determine the quality of agricultural products and foods. Conventional color measurements were performed destructively using laboratory equipment. Therefore, color measurement methods of agricultural products were needed more quickly, accurately and non-destructively. This study aimed to develop a Computer Vision System (CVS) that can be used as a tool to measure the color of fruits. The designed CVS consists of a 60x60x60 cm black mini photo studio; a pair 15 watt LED lighting, sony α6000 digital camera, a set of laptop and an image processing software applications. Image processing software was programmed using VB.Net 2008 programming language. The developed CVS was calibrated using 24 color charts Macbeth Colorchecker (Gretag-Macbeth, USA). The calibration results of 24 color chart of Macbeth Colorchecker was resulted in a MAPE (Mean Absolute Percentage Error) value of component R / Red = 0%; G / Green = 0% and B / Blue = 0,5%; with 99% accuracy rate. In color measurement, the developed CVS had a 95% accuracy rate.
