Abstract

The research aims to study the response of upland rice on the application of silicates and phosphate fertilizer on Ultisol. The study was conducted in land Ultisol in Pematang Berangan Village, Rokan Hulu Regency, Riau Province. Research in the form of experimental factorial completely randomized design consisting of two factors. The first factor is silicate consists of four levels (0, 50, 75, and 100 kg SiO2/ha), while the second factor that phosphate fertilizer consists of four levels (0, 36, 54, and 72 kg P2O5/ha), each combination was repeated three times. The results showed that application of silicates and phosphates increase the growth and yield of upland rice. The application of 100 kg SiO2 and 36 kg P2O5 per hectare increasing of the percentage of grain pithy and weight of dry grain per square meter, about 21% and 117% respectively compared to without silicates and phosphates.

Abstract

The objectives of this research were to estimates the  genetic diversity and heritability of production characters and fruits quality of papaya on two harvest periods.  This experiment was conducted at three locations e.i Bogor, West Java from Januari 2012 to March 2013. The treatments  were arranged in randomized complete block design (RCBD), consisting of 15 genotypes as treatment  with three replications at two harvest periods.  Data observed were analysed by analysis of variance and mean square of each character was used to estimate the number of genetic diversity and broad sense heritability (h2bs).  Character such  fruit weigth, fruit length, flesh hardness flesh thickness, fruit number, production per plant had high heritability.

Abstract

Rice as a staple food source of Indonesian people is still a top priority. However, efforts to increase rice production faced a variety of problems such as a decrease in the productivity of paddy fields due to the lack of organic matter. In addition to rice, meat is quite important food. To fulfill the need of domestic meat portion should be imported. This is an opportunity for the development of cattle breeding business in Indonesia. Crop Livestock Systems Integration (CLS) is one alternative in increasing the production of rice, meat, and dairy while improving the welfare of farmers and ranchers. There are three main technology components CLS namely: 1). Rice cultivation technology, 2). Livestock farming technology, and 3). Straw and compost processing technology. Technology components that can be integrated synergistically, then CLS development done by the institutional approach. CLS program aims to optimize the utilization of local resources such as the use of straw as livestock feed and cow manure can be processed into organic fertilizer that is very helpful to improve the nutrients that plants need so no waste is wasted (Zero waste). Utilization of cow manure was processed into liquid and solid organic fertilizer, is expected to serve as a source of additional income for farmers. Compost and liquid fertilizer and is expected to improve the fertility of agricultural land. CLS program was initiated in conjunction with a program of integrated crop management (ICM). In addition, the development of farming systems approach CLS needs to be done through farmer groups to facilitate agricultural extension, livestock grains technology adoption, and government aid channel. The advantage of the rice-livestock integration pattern that is the utilization of crop residues as a source of animal feed, utilizing livestock manure as fertilizer, creating new jobs in rural areas, and increase community participation in creating a competitive agribusiness, environmental friendly and independent. CLS constraints in achieving food security among farmers groups working mechanism was not going well, utilization of collective cages was not optimal, mentoring and coaching process was not effective because the cattle were scattered locations, the use of manure has not been entrenched among rice farmers, and the application of CLS conducted throughout provinces in Indonesia and there was no apparent progress. Repair CLS for the future should focus on the region so that large-scale production centers and significant impact on population growth and productivity of livestock. Livestock waste treatment close to the location of the rice to minimize transport costs so as to create zero waste and integrated farming systems to achieve food sovereignty.

Abstract

Watermelon is a horticulture plant that much like by the general people. The sweet taste and high water content of watermelon often used as a food or beverage that is refreshing. The watermelon consumption produces waste including peel of watermelon. And the peel of watermelon contains a lot of useful components including pectin. Pectin is a polysaccharide compound that consist of galacturonate acid molecules. Pectin is widely used as a functional component in the food, pharmaceutical industries, feed industry. Pectin is usually extracted by strong mineral acids. The use of mineral acids can be dangerous if the pectin is processed into food and can cause environmental problems. This study aims to utilize waste as an alternative source of watermelon peel pectin extracted enzymatically by Aspergillus niger. In this research, there are some of procedure namely the enzyme production of  Aspergillus niger, pectinase enzyme extraction, hydrolysis enzymatically pectin and pectin powder manufacturing process consisting of coagulation, sedimentation, drying to obtain dry pectin. The results showed that pectin in this research namely low metoxyl pectin 6.24%, yield 15.26 %, moisture content 11.46 %, ash content 4.8 %, equivalent weight 789 mg, galacturonate content 57.72 % and degree of esterification 61.33 %.

Abstract

Food is a basic need that the demand is increasing in line with the population growth. A new approach of agricultural development is needed in order to fulfill the food need in the present and the future. The approach is to determine the food security in a region by using the Food Security Atlas. The previous atlas is still in the national scale, so it needs additional researches in the local scale. This study aims to create a map of food vulnerability in the Purworejo district as an input to determine the food security. The parameters used to create the vulnerability map are the percentage of vegetated land area, rainfall anomalies, the percentage of crop failure area due to flood or pests, and land degradation due to erosion. Remote sensing data are used to create the percentage of vegetated land area map, land use map, land unit map, flood and erosion map. All parameters are given values to classify the food vulnerability. The results show that the vulnerable regions are not only in the transition area between hills and plain area, which are in Bruno, Pituruh, Kemiri, Kaligesing, and Loano sub-district, but also in the southern coastal region, which are in Ngombol and Grabag sub-district. Calculation show that the area of food secured regions in Purworejo are 63,11 km2, the secured enough regions are 804.96 km2, while the vulnerable regions are 218,24 km2 .

Abstract

Planting maize hybrid varieties tolerant to acid soils offers an alternative strategy for improving maize productivity in acid soils. The objectives of this study were to evaluate and select maize hybrids for high yield potential in acid soils. Fifteen single maize hybrids derived from a 6 x 6 diallel cross, six parental inbred lines and two chek varieties were evaluated in Ultisol at UPT Farm, Andalas University. The evaluations were carried out in a RCB design with three replications. Several hybrids had high yielding potential in acidic soils as the hybrids produced higher yield compared to Sukmaraga as a tolerant check variety. The results from combining ability analysis showed the preponderance  of non-additive gene actions in the control of yield in acid soils. The hybrids performed high and significant specific combining ability and also higher mid-parent and better parent heterosis, indicating that the heterosis breeding may be rewarding. Hence, it is suggested that these promising hybrids should be further tested before it is released as new hybrid varieties.
