Abstract

This study analyzed farmers’ perception about plant protection skills of extension workers in increasing the tomato production of District Peshawar, Khyber Pakhtunkhwa Pakistan. For the present study two villages each were taken purposively from three union councils of Town 2 of District Peshawar for data collection. Well-structured interview schedule was employed for data collection and SPSS V.20 software was used for analysis. Results were presented as simple percentages while Likert scale was used for ranking purpose. Above 40 years tomato growers were 30% where 37% owned 1-2 acres of land and majority (76.9%) tomato growers were literate. About 31% tomato growers were getting Pakistani Rupees 40,000-80,000 per season and maximum (52%) tomato growers were getting production from local varieties of almost 3,001-6,000 kg/acre. Farmers' perceptions about extension workers' familiarity for selection of economical methods for pest control was ranked first with highest mean value 3.1587 with SD 1.15421 and symptoms of insect/ pest infestation disease and their causes identification was ranked 2nd with the mean value of 3.0337 and SD 1.18925, while life stages of tomato insects identification was ranked 3rd with the mean value of 2.6635 and SD 1.20875 and knowledge of adverse environmental effects of pesticides was ranked 4th with lower mean value of 2.5096 and SD 1.34412. Knowledge about biological control of pest was ranked 5th with the lowest mean value of 2.1635 and SD 1.11737. Extension worker plays a significant role in enhancing the production of tomatoes as highly significant association existed between average yield of tomato and skills of extension worker regarding plant protection skills. The study recommends that extension personnel should visit tomato growers regularly at each stage to address their plant protection issues and recommend weather suitability of tomato varieties for higher production by protecting the crop from the damage of insects. Local agriculture programs should be broadcasted on FM channel and pamphlets may be used for creating awareness regarding tomato protection point of view.

Abstract

Extension is a form of effort to educate and improve the lives of Indonesian citizens. In particular, the performance of agricultural extension agents is a measurement of the success of agricultural extension activities. This is certainly inseparable from the quality of human resources that available in supporting the implementation of agricultural extension activities. Rantau Kasai Village is one of the villages located in North Tambusai Subdistrict, Rokan Hulu Regency, Riau Province, which based on data from the Agricultural Extension Agency has seven farmer groups and the majority of the population are farmers. Agricultural extension in Rantau Kasai Village has been carried out, but the level of farmers’ satisfaction with the performance of extension agents needs to be deeply investigated. This research was conducted using the survey method. Sampling using the Slovin technique obtained a sample size of 84 respondents from 174 farmers. The results showed that the level of conformity shows the highest level (100%), namely at the attribute of extension agents’ understanding to the specific needs of farmers and their groups. The results of Importance Performance Analysis (IPA) reveal that quadrant III (Low Priority) is the dominant quadrant containing 12 attributes of agricultural extension agents’ performance. The result of the Customer Satisfaction Index (CSI) analysis shows a value of 81.19% or 0.8119, which is classified into the “very satisfied” category, meaning the farmers are very satisfied with the performance of agricultural extension agents.

Abstract

Indonesia has a diverse range of fish species in both seawater and freshwater. Lampung is one of the provinces in Indonesia that has a rich diversity of fish species. Lampung has a wide variety of fish species, including tilapia. Tilapia is a food material that decomposes quickly due to bacteria and microorganisms. As a result, one of them is the need for profitable handling by utilizing smoking technology. Smoked fish is popular in Lampung, but the most commonly used fuel is coconut shell, coconut coir, and corn cobs. The use of common fuel in the community still cannot assess the smoking fuel that can produce good quality standards of fish. As a result of the aforementioned issues, the research was to evaluate effect of fuel quantity and type on the quality of smoked fish. The goal of this study is to determine the effect of fuel amount on tilapia smoking, the type of fuel that can produce smoked fish of optimal quality, and the cost of fuel needed for tilapia smoking using coconut shell fuel, coconut coir, and corn cobs. The method used in this study was organoleptic testing on 25 panelists using a smoked fish score sheet determined by SNI smoked fish, and then the panelists' scores were processed using excel. The amount of fuel used and the duration of smoking have no effect on the quality value of smoked fish, and the type of fuel that can produce smoked fish of optimal quality, namely coconut coir, passed the SME (export quality certificate)  standard with an organoleptic value of smoked fish of 8.0.

Abstract

Lampung province is one of Indonesia's cassava production centers. Lampung Province is currently Indonesia's largest cassava producing area, capable of producing 60 percent of the country's tapioca needs. Cassava chips are not a new product for Indonesians. Processing cassava into thick cassava chips using vacuum frying technology is a promising technology that can increase the economic value of cassava tubers while also meeting consumer demand for innovation in the shape and size of cassava chips. The problems investigated in this study include determining the optimal temperature required to produce thick cassava chips of the highest quality and the optimal pressure required to produce thick cassava chips of the highest quality. The aims of this study was to determine the optimum temperature and pressure required to produce thick cassava chips with the best quality at temperatures of 80 C, 85 C, and 90 C and pressures of -65 cmHg, -68 cmHg, and -72 cmHg. Data analysis in Microsoft Excel software using Anova analysis to determine the effect of temperature and pressure on frying time, moisture content, weight loss, and organoleptic test. The effect of temperature and pressure on the frying using vacuum frying in the manufacture of thick cassava chips was studied. Temperature and pressure affect the water content, length of frying, and organoleptic test of aroma, color, taste, and crispness. The best quality of thick cassava chips has the lowest moisture content of 3.01% and the shortest frying time of 38 minutes, as well as the favorite score of the hedonic aroma test 3.87, taste 4.37, color 4.17, and crispness 4.73 on a scale of 1-5 contained in the treatment with optimal temperature and pressure, temperature 90 C and pressure -72 cmHg.

Abstract

Pakcoy is a leaf vegetable of high economic value and rich in nutritional content so it is greatly demanded by the public. This study aims to analyze the effect of using several types of planting media on the growth and yield of pakcoy plants with a hydroponic system; analyze the type of planting media that mostly affect the growth and yield of pakcoy plants; and analyze the feasibility of pakcoy cultivation with a hydroponic system using several types of planting media. This research was conducted from February to March 2021 in Kandang Lamo, Sarilamak, Harau Subdistrict, Lima Puluh Kota Regency, West Sumatra. Data were analyzed using a complete randomized design (CRD). There were three treatments using several types of planting media with three replications simultaneously covering a total of 81 plant samples. Data were analyzed with ANOVA, then continued with DMRT 15%. Financial economic analysis was measured by calculating revenue value, R/C ratio, BEP, and profitability ratio. The results reveal that the treatment of several types of planting media has not significantly affected the number of leaves and leaf’s width, plant’s height and plant’s fresh weight. The highest average value is resulted by the brick fragments planting medium treatment. It is proven from the average results on the leaf’s width (11.04 cm) and the number of leaves (17.03) at the age of 4 weeks after planting. The highest production yield value (131.24 gr) is resulted by the rockwool planting medium treatment. The results of the financial economic analysis show that the pakcoy cultivation business with a hydroponic system using various types of planting media is feasible to be continued. It is proven from the variable analysis of the business profit and loss statement on the parameter of R/C ratio and the profitability ratio.
