Abstract

Organic farming is the key to agricultural sustainability in the future, but farmers have not implemented it much.  This study aims to determine the application of technology in organic rice cultivation to farmers in the Sri Jati Kalurahan Jatisarono Farmer Group, Kapanewon Nanggulan.  This research uses descriptive qualitative with observation and interviews.  The research was conducted from January to June 2022.  The location determination technique is carried out by purposive sampling.  The data was analyzed by benchmarking, namely comparing businesses at the research site with more advanced organic rice businesses.   The results of the study showed that the application of technology in the Sri Jati Farmer Group compared to the Makmur Farmer Group showed differences in the selection of seed varieties. Pros: on the method of cultivation, and harvesting. While the similarities are in aspects: land processing, seeding seedlings, and weed control. Weaknesses in aspects: fertilization and control of pests. Empowerment activities are emphasized on making fertilizer with rabbit urine and controlling pests with natural ingredients.

Abstract

PT Menthobi Makmur Lestari is a growing industrial company in the field of palm oil production. The company is targeting increased palm oil production to forecast capacity plans and manufacturing facilities. One of the prediction methods used is multiple linear regression. The free variables used for prediction are the age of the tree, land area (ha), number of trees, number of vines, and the bound variable is the yield of oil palm production. The results of the correlation test using multiple regression showed a significant correlation of 0.05 or less. Hypothesis testing includes multiple linear regression and correlation using the t test and f test with a significance level of α = 0.05. The value of multiple correlation analysis (R) is 0.947 and the coefficient of determination is 90%. The performance of the multiple regression equation is the accuracy of predictions with an average absolute error percentage (MAPE) of 21%, which is formed from the validation of training and testing data.

Abstract

Sago plant (Metoxylon SP) for the community in the Regency of the Meranti Islands has an important role in the life and economy of its people. The prospect of developing the sago business in Meranti is still promising because   The land used has only reached 43% of the available land,  and management can still be optimized.  Sago processing that is currently operated is still running conventionally. That is, it only produces sago starch products. Its by-products in the form of waste from the pulp (repu) and skin (uyung) have not been optimally utilized. This study aims to optimize the processing of by-products into high-value products through improving sago management towards the concept of a zero waste industry in the Meranti Islands Regency, Riau Province. The results of the research that has been carried out show that it is necessary to add a process flow to the processing so that the resulting sago repu is not wet. The resulting dried sago repu will expand its utilization. From supporting studies, the results of studies  that have been carried out show that fermentation using  Trichoderma can increase protein by 18-22%. Using this Trichoderma mushroom, sago pulp can be used as animal feed or as raw material for biomass

Abstract

The use of traps is one of the environmentally friendly pest controls. Insects have a preference for the colour of objects. The research aims to determine trap colours' effectiveness in catching rice plant pests. The research was conducted from  June to July 2021 in Depok, Sleman Regency, Yogyakarta Special Region. The study used a descriptive observational method on an 8-week-old rice planting area. The colour traps used are white, red, green, yellow, and blue.  The experiment used a completely randomized design with five replications. The results showed that the yellow trap produced the most insect catches, namely 545 insects, and the white colour produced the lowest catch of 74 heads.  Pests that are heavily trapped in a row from the most to the least are Hydrelia sp, Leptocorisa oratorius,  Nephotettix virescens,  Pareaucosmetus sp, and Nilaparvata lugens. The most trapped is Hydrellia sp, as much as  78% of the total trapped insect pests. Effective trap installation time in the morning.

Abstract

Sumberbrantas village is one of the areas located in the highlands which is one of the potential for potato commodity development. The high potential of the region is also supported by the willingness of farmers to cultivate potatoes. The purpose of this study was to determine the marketing channel for potato commodities and the efficiency level of marketing institutions for potato commodities in Sumberbrantas Village, Bumiaji District, Batu City. This study uses the Cluster Random Sampling method. In this study only covers the city of Malang and Batu city. The samples that will be used as respondents in the study are 30 potato farmers, 2 collectors, and 4 retailers. Data analysis used descriptive analysis, marketing margin analysis and Farmer's Share analysis. The results of this study are farmers - collectors - retailers - consumers. The marketing margin value for each potato in this marketing channel is IDR 3,500. The share value or profit share is 90.76% and the cost share is 9.2% so it can be concluded that this marketing channel is logical because the profit share value obtained is greater than the cost share in the marketing channel. The average selling price received by farmers is 9,500/kg. the value of PS or the percentage of farmers' profits is 73.07% of the price at the consumer level, which is Rp. 13,000/kg.
