The village of Sugihwaras of Lamongan Regency is an agricultural area where most of the farmers are paddy farmers with female farm workers. One aspect to examine in the area is the role of rural women in agriculture as members of the household, the outpouring of workdays they do for their daily activities, and to what extent this affects their family's farming income. The study aimed to determine the number of working hours and the contribution of female farm labourers to household income. The study employed a simple random sampling of 60 respondents with interview techniques using a questionnaire. The method of analysis was descriptive analysis. The results obtained that the working hours of female farm workers for one year per hectare of the land area were 540 hours, devoted to paddy farming twice annually. The contribution of female farm workers to household income was IDR 1,687,500 per month or IDR48,600,000 per year per hectare, from paddy farming for two growing seasons annually. It is suggested that the amount of working hours and the contribution of female farm workers to household income is very small, so efforts should be made to increase the number of hours they work so that the income they earn can increase. Efforts are being made, namely raising livestock, as well as training in the manufacture of processed by-products of agriculture, for instance by making sweet potato chips and other preparations that can be sold.

The Lahoten Musan Kabuar and Lahoten Musan Lotuk Naruk varieties are two introduced rice varieties from Timor Leste. Optimization of cultivation techniques using organic fertilizers with different doses is carried out to obtain the best growth and yield quality. The research was carried out from December 2021 to April 2022 using the CDAST laboratory greenhouse at the Universitas Jember. The experimental design used a completely randomized design (CRD) with two factors. The main factor is the type of rice varieties which consists of 2 levels, namely the Lahoten Musan Kabuar variety (V1) and the Lahoten Musan Lotuk Naruk variety (V2). The second factor is the dose of organic fertilizer application, which consists of 4 levels, namely 0 tons ha-1 (P0), 2 tons ha-1 (P1), 4 tons ha-1 (P2), and 6 tons ha-1 (P3). The results showed an interaction between the use of organic fertilizer and the type of varieties on plant height, chlorophyll content, protein content, fat content, and amylose content. Whereas the application of organic fertilizer had no significant effect on the parameters of the number of tillers, number of panicles per plant, number of seeds per panicle, the weight of 100 seeds, carbohydrate content, and water content. The results of DMRT on interaction parameters show that the organic fertilizer dose factor has a more dominant influence than the variety factor.

Shallot (Allium ascalonicum L) is one of the horticultural plants that acts as a natural antioxidant. Shallot's productivity in Indonesia is relatively low. It is influenced by various factors, one of which is due to the attack of a soil-borne pathogen, namely Fusarium oxysporum. Symptoms of Fusarium oxysporum pathogen attack are yellow or pale green leaves and more elongated growth. Severe attack leads plant to death. Balanced fertilization and biopesticides application can prevent Fusarium wilt. This study aims to reduce and control Fusarium wilt disease. The research method used was the Split Plot Design method which consisted of two factors with the main plot, namely the application of suspension of microorganisms (S) which consists of two levels, namely fungicide application (S0) and Fobio application and the sub-plot, namely the application of various organic fertilizers (M) which consists of three levels, namely control (chemical fertilizer) (M0), chicken manure (M1), and Piensbio organic fertilizer (M2). Observation data for each treatment will be analyzed using analysis of variance (ANOVA) followed by the Duncan test (alpha 5%) if there were differences in each treatment. The results of this study, the main plot treatment, fungicide application (S0), showed an incubation period of 29 days and an average intensity of disease attacks of 4.2%. The treatment of subplots, a type of organic fertilizer (M), is unable to suppress the intensity of the attack and slow down the incubation period of the Fusarium sp on shallot crops. There was no interaction between the treatment of the main plots and the subplots on all the observation parameters.
