This study aims to identify 1) the source of production risk in some indigenous leaf vegetables, especially basil 2) the level of risks encountered, and 3) formulate strategies tocontrol the risk of production of indigenous leaf vegetable. The research was conducted in Kecamatan Kadudampit Sukabumi, the method of sampling used simple random sampling.The number of farmers were 42 farmers. In specialization activities, the method to process risk data used are analysis of variance, standard deviation and coefficient of variation. Theresults showed that the source of production risk faced by farmers were weather / climate, pest and disease diseases and seed quality. The expected return value of basil commodityRp.1.801.204 with the risk level of losses was 0.382 or 38%. Strategies that could be done to reduced the risk was the diversification activity with . timing and appropriate commodities of diversification activities, plan intercropping cropping pattern between two combination basil with lettuce were 60% and 40% and basil with gourd were 60% and 40%, risk managementin production through preventive strategies with improvement of physical facilities and mitigation strategies with pest and disease controls encountered.Keywords: basil, variance analysis, standard deviation, coefficient of variation, risk management.

The activity of the caudal photoreceptor of crayfish was studied in: (1) intact tail ganglion, (2) partially isolated, and (3) totally isolated ganglion preparations. Statistical analysis of the photoreceptor activity included average frequency, average interval, variance, standard deviation, coefficient of variation, interval histograms, auto-expectation density, and cross-expectation density. Results showed that the average influence of the mechanoreceptor synapses on the photoreceptors during a period of several seconds was inhibitory, strong on the contralateral and weak on the ipsilateral side.

The study focuses on the participation of community through PTC in the arrangement of different curricular and co-curricular activities in schools for betterment of students and enhancement of their qualities. A valid and reliable questionnaire was served to the two categories of stakeholders i.e. PTC members (Chairman and secretary) and Non-PTC members (Parents and Teachers). A sample of one hundred schools randomly selected from two districts of Khyber Pakhtunkhwa. Mean, Standard Deviation, Coefficient of variation, t-distribution and p-value were applied as statistical tools. Responses of both groups show moderate response and show that participation of community is found for the first variable i.e. arranging curricular activities but there is opposite opinion found in the point of view of both group regarding the arrangement of co-curricular activities in schools; response of PTC members group is positive but non PTC members group did not support it.

Production Risks

The fluctuation of potato production has been caused by production risk in on-farm sector. This research aims to identify the sources of production risk in potato production and analyze the strategies to overcome the production risk. This research was conducted at Cantigi Farmers’ Group, which has been actively producing potato in Cikajang Sub-district, Garut Regency, West Java. The data were collected from all 35 members of the Cantigi Farmers’ Group. This study used Z-Score and Value at Risk analyses. The results showed that the sources of potato production risk that occurred in the Cantigi Farmers’ Group were pests, diseases, rainfall, seed quality, managerial ability and soil fertility. Mitigation strategies can be used to overcome the risk sources such as by using intercropping method, plant-based pesticides, natural enemies, proper water management and drainage. Preventive strategies can be used to overcome the risk sources such as by using plant-based pesticides, organic fertilizers, assistance from local extension agents, in collaboration with certified seed breeders in the surrounding area and attending the training of how to breed properly. The research on potato production risk in Cikajang Sub-district is very significant considering that, to the best of authors’ knowledge, the analysis of potato production risks has not been conducted yet in this important area of potato producing. This study was conducted in a limited scope of variable, therefore, a further research of potato production risks is suggested to be performed in a wider variable scope.

This research aims to know the farming income of organic rice; production risk and price risk faced by the organic rice farmers. This research was conducted in North Lampung Regency in March-April 2019. This sample of this research consists of 31 organic rice farmers which are taken by using census method. Thedata analysis method are farming income analysis and risk analysis which uses statistics method by counting variance, standard deviation, and coefficient of variation (CV). The results showed that the average of farming income that was achieved by organic rice farmers amounted to IDR 60,525,621.96. The production and price risk are classified into the low category because the value of CV of production risk is 0.13 and CV of price risk is 0.10.Key words: income, organic rice, risk.

The development of shallot farming in Adipala Sub-district starting in 2018 faced several problems, namely most farmers still had low experience of shallot farming, the type of land that was less fertile, shallot seeds from Brebes which were not specific to coastal land. This research aimed to analyze 1) revenue, cost, income, and R/C, 2) the level of production risk, 3) factors influencing production, 4) factors influencing production risk. The research object was farmers who carried out shallot farming during the growing season from November 2019 to January 2020 in Adipala Village, Bunton Village, and Karanganyar Village. The sampling method was saturated sampling. Data analysis consisted of analysis of revenue, cost, income, R/C, coefficient of variation, and Just & Pope production risk function regression. The results showed that the shallot farming in Adipala Sub-district was profitable, namely per farm it had revenue Rp10,834,600.00, cost Rp9,999,943.61, income Rp834,656.39, and R/C 1.06. The production risk level was high at 85.49%. Factors that had been shown to significantly influence production were land area, seedlings, labor, agricultural lime, petroganik, manure, TSP, ZA, KCl, NPK, herbicides, and fungicides. Meanwhile, factors that had been shown to significantly influence production risk were TSP, NPK, and fungicides.

We investigate the risk relevance of the standard deviation of three performance measures: net income, comprehensive income, and a constructed measure of full-fair-value income for a sample of 202 U.S. commercial banks from 1996 to 2004. We find that, for the average sample bank, the volatility of full-fair-value income is more than three times that of comprehensive income and more than five times that of net income. We find that the incremental volatility in full-fair-value income (beyond the volatility of net income and comprehensive income) is positively related to marketmodel beta, the standard deviation in stock returns, and long-term interest-rate beta. Further, we predict and find that the incremental volatility in full-fair-value income (1) negatively moderates the relation between abnormal earnings and banks' share prices and (2) positively affects the expected return implicit in bank share prices. Our findings suggest full-fair-value income volatility reflects elements of risk that are not captured by volatility in net income or comprehensive income, and relates more closely to capital-market pricing of that risk than either net-income volatility or comprehensiveincome volatility.

ABSTRACT: This research was conducted to propose a classification of the coefficient of variation (CV%) in many categories of variables of production and carcass of beef cattle experiments. The data was collected from theses and dissertations. We used the methods of classification considering mean and standard deviation, and considering median and pseudo-sigma. The two methods showed similar results so both can be used to classify CV%. We propose only three categories to rank CV%: low, medium and high.
