Emergency food is needed when a disaster occurs. Emergency conditions encourage the provision of food that is ready to eat with sensory properties that can be accepted by the community, has sufficient nutrient content to meet the body's caloric needs and is resistant during storage. This study aims to obtain the best formulas of the food bar based on the parameters observed, namely sensory, chemical, total caloric, and aw as well as its shelf life estimation with the Accelerated Shelf Life Test. Food bar was made from white millet flour and fish koya that was made from snakehead fish and soy flour. Intermediate moisture food (IMF) applied in this study with the initial formulation was determined using mass equilibrium. The effectiveness test was used to determine the best formula based on all observed parameters. The results showed that the best food bar formula was formula F2, which has a chemical composition consisting of moisture content (20,99±0,21%); ash (3,45±0,35%); fat (18,10±0,13%); protein (12,24±0,28%); and carbohydrates (45,22±0.32%), aw (0,76±0,01); and total calories (per 50 g) was 232,04±1,96 kcal. The shelf life of food bar F2 was 19 days. Based on the results obtained, the total calories produced from the best formula have not met emergency food calorie standards.

Heterosis is often utilized as a success indicator in a crossbreeding program. It is defined as the deviation of the crossbred means relative to their parental breeds. Heterosis mechanism is highly dependent on the genetic factors and thus, we incorporated genetic information in its estimation. The objective of this article was to compare heterosis estimated with conventional and mixed model approaches. In total, phenotypes of 3804 individuals were recorded. Data were obtained from a crossbreeding experiment involving Boer bucks and Jawarandu does. Observed traits were birth weight, weaning weight and average daily gain. Conventional and mixed model methods were used to estimate the heterosis. The heterosis values (%) between BÃ—B vs BÃ—J, estimated with conventional method were -11.38, -10.51 and -10.39; with mixed model were -6.23, -9.27 and -9.68 for BW, WW and ADG respectively. Heterosis values in BÃ—(BÃ—J) relative to BÃ—B, estimated with conventional method were -6.16, -10.35 and -11.69; whereas with mixed model were -8.01, -10.82 and -9.14 for BW, WW and ADG respectively. Conventional method tends to underestimate the means phenotype with lower standard errors compared to mixed model analysis results in all traits. Conventional method also introduces biased heterosis estimates compared to the mixed model. Conventional method ignores any potential effects in the estimation procedures; whereas mixed model approach incorporates all the systematic and random effect including family relationship information. Thus, mixed model produced more reliable results in genetic parameters estimation. We recommend employing mixed model analysis in estimating heterosis.

Carbon stock is one of the essential types of ecosystem services that are provided by vegetation. Land use has significant effects both directly and indirectly on vegetation cover and strongly influences the carbon stock within the ecosystem. In this study, we have investigated the effect of land cover changes on the carbon stocks at the sub-watershed of Sumber Brantas, Batu city, East Java. This research was conducted at the Junrejo, Batu and Bumiaji districts of Batu city. Land cover classes were determined from satellite imagery. The carbon stock was measured at plot and landscape level using RaCSA. The results showed that forest conversion into plantation forest (pine, Teak, Albizia chinensis, Anthocephalus cadamba) or agricultural land caused losses of the above-ground C-stock of ~50 Mg ha-1, while losses of the underground C-stock were ~20 Mg ha-1. Tree biomass contributes about 60% of the C-stock on average, while the understorey and necromass contribute C-stock about 2% and 5%, respectively. Mixed forest has a total C-stock as much as 316.64 Mg ha-1, followed by plantation forest (247.19 Mg ha-1), farmland and scrubland i.e. 51.57 Mg ha-1 and 12 Mg ha-1,respectively. As the consequences of forest conversion into cropland (2008~2012), the Sumber Brantas sub-watershed (139,447 ha) has been lost its C-stock as much as 0.83 Mg ha-1 yr-1, equivalent to 3.04 Mg CO2 ha-1 yr-1. This study showed that C-stock will be maintained by managing and planting woody plant which has high tree biomass.

Black rice is one of fungtional food sources. The obstacle of its cultivation is availability of qualified seeds and organic fertilizers input. This research aimed to determine the effect of stable manure on growth and yield of black rice, to observe the effect of seddling number per planting hole and to obtain the best combination of stable manure and seedling number on the growth and yield of black rice. The research was conduct in rice field on Karanglewas Kidul village, Karanglewas district, Banyumas, Central Java during April until September 2016. This research used a split plot design, with 3 repetition. The main plot was three type of stable manure (chiken, goat and cow), while the subplot was seddling number (1, 2 and 3). Data was analyzed using ANOVA and DMRT at p 0.05 level. The results showed that chicken manure gave the highest productivity rice of 5.15 tons ha-1. The 1 seedling each hole gave the highest result on panicle length and grain number per panicle. The better combination treatment was chicken manure and three seedling per planting hole wich gave the highest grain yield of 5.38 tons ha-1.

Ethiopia is one of the most vulnerable countries to climate change and often signifies higher probabilities of droughts that have historically affected millions of farmers. The variability in rainfall patterns and drought have disrupted crop production and exacerbated food insecurity in many parts of Ethiopia. This study aimed to investigate seasonal and annual temperature and rainfall trends and their association to the global CO2 emission. Temperature and rainfall data obtained from the Masha meteorological station and CO2 from EDGAR 4.3.2 dataset recorded for 36 years. The Linear regression model was used to analyse seasonal temperature and rainfall trends. Pearson’s correlation coefficient employed to measure the relationship between temperature and rainfall and global CO2 emission. The results showed that there were significant warming trends of seasonal and annual mean temperatures while summer season and annual rainfall significantly declined. The prediction results showed that the summer and annual mean temperatures would be significantly increased while the rainfall decreased for the next 35 years. The cumulative global CO2 and annual mean temperature and rainfall were correlated significantly at P = 0.0004 and 0.006 for temperature and rainfall, respectively. The results demonstrated clearly that the increasing of temperature and the decreasing of rainfall had a direct relationship with the global CO2 emissions and suggested that there should be a sound soil and water management, short season seed supply and pipe irrigation practices to reduce the future crop damage in the area.

The low soil fertility is one of the causes of the reduction in cassava production in the Nuabosi area of Ende Regency. Therefore it is necessary to identify soil fertility and farmer activities on the land. This research used survey system by takes soil samples and farmers from ten fields in five villages, namely Ndetundora I, Ndetundora II, Ndetundora III, Embuteru and Randotonda. Determination of land were used purposive sampling method. Whereas farmer activity data is obtained by interviewing farmers whose land is used as land sampling. Variables observed were physical and chemical soil properties. The results of the analysis of agricultural activities can be described using existing theories. While the analysis results of the physical and chemical properties of the soil can be described using chemical criteria and soil fertility from the Bogor soil research center. The results of interviews and direct observations in the field showed that Nuabosi cassava farmers did not only plant cassava but also used conservative agricultural on their land. The physical properties of the soil analyzed showed that the soil was suitable for cassava plants. Based on soil fertility criteria, these lands have a limiting factor for C-Organic.

P fertilization can add Cd metal content to agricultural land because the raw material for making P fertilizer comes from phosphate rock which naturally contains Cd metal. Farmers assume that by providing fertilizers with high doses can provide maximum results. Community’s knowledge of heavy metals in the environment is still low. This study aims to examine the awareness of farmers in Sragen Regency Central Java to the potential of heavy metal pollution that occurs. This research was conducted from July to December 2017. The type of this research is quantitative descriptive research using a questionnaire with the number of respondents amounting to 10% of the number of farmers, namely 30 farmers. The results show that about 61.11% of the community doesn’t understand that the presence of heavy metals in the environment can cause many problems. About 60% of the community doesn’t understand that the inorganic fertilizers commonly used by them contain heavy metals (especially Cd metal). People unaware of heavy metal pollution due to over-fertilization is 65.01%. Although the community's knowledge and awareness of heavy metals are still low, the community awareness about environmentally friendly agriculture is high (61.33%). About 53.34% of the community doesn’t know that their behavior in using inorganic fertilizers in the long term will increase the accumulation of Cd metal in agricultural land and rice plant tissue. About 70% of the community doesn’t know that agricultural land that is used continuously to plant (without interspersed with non-paddy crops) will cause land degradation.

Planting drought-resistance plants in terms of agronomy, such as induction of plant tolerance using calcium is assumed to be able to solve the climate anomaly problem. Calcium is known as an element that plays an essential role in determining the response of plant resistance to drought through biochemical activity. This study aimed to determine the role of calcium in changing photosynthesis activity in order to increase the resistance to drought stress. The treatment was arranged in factorial of 3 x 4 in a split plot Randomized Complete Block Design replicated three times. The first factor was the dose of calcium application consisted of 0 (control/without calcium), 0.04, 0.08 and 0.12 g. The second factor was the intensity of drought stress, which referred to the Fraction of Transpirable Soil Water method consisted of 1 (control/field capacity), 0.35 (moderate drought) and 0.15 (severe drought). The measurement data of stomatal aperture, Abscisic Acid (ABA) content, chlorophyll content, carotenoid content, proline content, nitrate reductase activity and photosynthesis rate that fulfill the assumption of homogeneity and normality were analyzed using variance at 95% accuracy and continued using DMRT. Moreover, regression analysis were determined of relationship between the treatment and parameters. The results revealed that drought resulted in a decline in leaf water potential and stomatal aperture. The effects of calcium on chlorophyll and carotenoid under drought stress could not be explained in this study. However, the application of calcium has a significant effect on decreased ABA, increased proline and nitrate reductase activity resulting in an increase in the photosynthetic rate of oil palm seeds in drought stress.

Batujai Reservoir locates in Batujai Village, Praya Barat, Central Lombok, West Nusa Tenggara. It is the primary source of irrigation water supply for agriculture in Central Lombok District with an area of around 3,235 ha. The problem is the bloom of water hyacinth weed (Eichhornia crassipes), which can cause reservoir water loss through evapotranspiration, affecting the amount of water reservoir available for the dry season. The objective was to identify the area of cover and estimate water loss through water hyacinth evapotranspiration for the period 2013 – 2017. This study used a descriptive method by analysis of secondary data which were meteorological data and landsat-8 satellite imagery. Evapotranspiration analyzes use CROPWAT 8.0, monitoring water hyacinth cover using landsat–8 satellite imagery processed using ENVI 5.3 and ArcGIS 10.4 software. The results show that the spatial distribution of water hyacinth can be detected and mapped accurately with an overall classification accuracy of 84.11% – 97.04% using Landsat 8 data, with a kappa coefficient of 0.80 – 0.96. The area of water hyacinth cover ranges from 38,400 m2 – 2,158,500 m2, with a cover area of more than 20%, causing water loss above 8,000 m3 day-1, which occurred in April 2013, April 2015, April 2016, February 2015, May 2014, May 2016 and July 2016, in those months it was seen that the amount of water loss was greater. Therefore, it is needed to suppress the growth of water hyacinth, in maintaining reservoir water storage capacity to support a systems of sustainable agriculture.
