Jam is a semi-solid food ingredient made no less than 45 parts by weight of crushed fruit with 55 parts by weight of sugar. The mixture is thickened until it reaches a content of a dissolved solid substance of not less than 65% for all types of jam. The main components or conditions for making jam are pectin, sugar and acid. Pectin requirements for the manufacture of jams are a maximum of 0.75% and a minimum sugar of 55%. Ideal fruits in the manufacture of jam should contain enough pectins and acids to produce jams with appropriate characteristics.Research on the jam characteristics of various yellow pumpkin and watermelon peel balances has been tried with the aim of establishing the right balance. The method used in this study was an experimental method using a Randomized Block Design. The balance treatment of yellow pumpkin and watermelon peel consists of balancesA (100: 0) , B (90 : 10), C (80 : 20), D (70 : 30), E (60 : 40) and F (50 : 50), each treatment is repeated four times. Inter-treatment testing using duncan multiple range test at a real level of 5%.The results showed that the balance of yellow squash and watermelon peels gave a noticeable difference in the effect on the moisture content, vitamin C, total soluble solids, the degree of liking for the color, taste, aroma and consistencyof the jam. The balance of yellow pumpkin and watermelon peel (70:30) produces good jam characteristics, this determination is based on a color favorability level of 4.16 , taste of 4.04 and consistencyof 3.63 out of a maximum value of 5.00 and a total soluble solid of 70.03%.

The Potato Tuber Moth (Phthorimaea operculella) is a destructive pest that poses a significant threat to stored potato crops, leading to substantial economic losses worldwide. The use of chemical insecticides to control this pest has drawbacks such as environmental pollution and potential harm to human health. As a result, it is critical to investigate alternate control strategies, such as botanical extracts. This study aimed to evaluate the efficacy of different botanicals, Azadirachta indica (Neem), Acorus calamus (sweet flag), Sapindus mukorossi (Soapnut) and their combination against the Potato Tuber Moth in stored potatoes. The research followed a randomized sampling technique, with seven treatments {T1: sweet flag (100%), T2: Neem (100%), T3: neem (50%)+ soapnut(50%), T4: soapnut powder (100%), T5: sweet flag (50%)+ Neem (50%), T6: sweet flag (50%)+ soapnut(50%), T7: control }. The treatments were applied to potatoes and data were observed, recorded, and tabulated. Our results showed that there was not a huge difference in the final result of mortality in all the treatments, all showing similar results. But when observed by counting the time factor, Acorus calamus outsmarted other bio-pesticides by killing 100% of insects in much less time. Further, all the treatments significantly affect the weight loss of potato tuber. Potato tuber treated with T1 showed the least weight loss of 1.88% of total weight followed by T6 and T4 with 2.56% and 2.58% of weight loss respectively. There was also some weight loss in the untreated potatoes due to evaporation and other physical factors. To sum up the overall result of our study, the experiment concluded that Acorus calamus (T1) had given the best result and thus it stood to be the best bio-pesticide among all.

This article introduces a novel approach resulting from the adaptation of Trapezoidal-Newton method variants. The iterative process is enhanced through the incorporation of a numerical integral strategy derived from two-partition Trapezoidal method. Through rigorous error analysis, the study establishes a third order convergence for this method. It emerges as a viable alternative for solving nonlinear equations, a conclusion substantiated by computational costs conducted on diverse nonlinear equation forms. Furthermore, an exploration of basin of attraction analyses that this method exhibits faster convergence compared to other Newton-type methods, albeit with a slightly expanded divergent region with a variant of Newton Simpson’s method.

Aquaculture is a rapidly growing industry and has enormous potential to increase the income and welfare of fish farmers. The majority of aquaculture businesses in Indonesia are small-scale cultivators, low productivity and limited business accessibility. As a result, there is an aquaculture industry that does not understand the use of aquaculture-specific financial risk management tools. Therefore, an insurance instrument is needed to manage losses that occur so as to achieve financial and income benefits, namely Micro Insurance. This study aims to calculate premium prices with a standard deviation principle approach. The data used is loss data if aquaculture cultivators do not pay in accordance with the initial capital in Tasikmalaya obtained through primary data based on the results of field surveys through questionnaires. The method of analyzing the number of event data uses the Poisson distribution, while the loss data uses the Exponential distribution. Next, calculate the parameter estimation using the Maximum Likelihood Estimation method. The results of parameter estimation are used to find a collective risk model. From the calculation results in this study, a premium price of IDR was obtained.
