The Food Estate (FE) program initiated by the government seeks to accomplish this through extensive and intensive farming practices while taking sustainability into consideration. In this paper, a multidimensional scaling (MDS) approach to determine the status and model of agricultural sustainability of the FE program was adopted. Three scenarios were developed to improve the sustainability status based on primary data from interviews with 50 farmers in Ria-Ria Village, Pollung District, North Sumatra. The findings indicate that the farming status is at a moderate sustainability, and improving all aspects can significantly increase the sustainability value. The study suggests that the government should prioritize the improvement of all aspects to raise the sustainability status of FE farming in order to achieve food security.

The results showed that chrysanthemum farming in DI Yogyakarta is cultivated on a flat to hilly topography, and the cultivation method is simple and conventional in a plastic house (gauze). Rust disease caused by Puccinia horiana is found in Sleman and Kulonprogo Regency with varying degrees of severity. Chrysanthemum rust disease has random disease distribution which means that the cause of the disease is dispersed by the wind or by seeds. P. horiana spores are dispersed by the wind and can be caught with Kiyosawa-type spore traps at an altitude of 0.5-1.5 m from the soil surface. The highest intensity of chrysanthemum leaf rust disease is found in ...

In 2006, the symptoms of leaf rust were initially found in chrysanthemum farms in village of Hargobinangun and surrounding areas. Since then it has been consistently spreading to other areas throughout Yogyakarta-Indonesia. Puccinia horiana is closely associated with rust leaf disease. This research was aimed to investigate the distribution, incidence, and severity of chrysanthemum rust disease in chrysanthemum plantations in Yogyakarta. The survey was conducted based on a randomized stratified approach. The entire district was divided into five observation sites, with each location consisting of three to four chrysanthemum farm sites owned by farmers. The results showed that rust leaf disease was distributed in all sites. The average of disease incidence found in the observation sites was 97.13%, meanwhile the average of disease severity was 55.19%. The highest disease incidence was found in Kaliurang 98.44%, followed by Wonokerso of 98.33%, Gondanglegi of 96.87%, Boyong of 96.25%, and Sidorejo of 95.83%. The highest disease severity was found in Wonokerso 58.75%, followed by Gondanglegi 56.92%, Kaliurang 53.39%, Sidorejo 54.89%, and Boyong 52.01%. The lower plant cultivation site, the lower incidence of rust disease.

At present, S. aureus from SCM in PE goats in Yogyakarta has not been characterized. Therefore, this study aimed to phenotypically characterize S. aureus, which has been isolated from SCM of PE goats. Materials and Methods: A total of 314 lactating PE goats were collected from 60 PE goat farms (e.g., Sleman, Bantul, and Kulonprogo) located in parts of Yogyakarta with an average age of 3-4 years old, three of which showed SCM based on the California mastitis test (CMT). Subclinical mastitis is confirmed in PE goats if CMT shows ++ or +++. Furthermore, S. aureus was detected by biochemical assays. Staphylococcus aureus could determine hemolysin (Hae), coagulase (Coa), clumping factor (Cf), and antibiotic susceptibility. Hemolytic bacteria were detected by culturing on blood agar plate, and Cf was detected by slide agglutination. The production of Coa was detected by tube coagulation. Staphylococcus aureus susceptibility was determined by antimicrobial agar diffusion using a paper disc. Results: Phenotypically characterized S. aureus from PE goats with SCM in Yogyakarta, Indonesia, Coa−, Cf−, and Hae− were found to be resistant to erythromycin (ERYTHRO), ampicillin (AMP), penicillin (PEN-G), and sulfamethoxazole (SULFA). Conclusion: The phenotypic characteristic of S. aureus, which was obtained from SCM in PE goats in Yogyakarta, consists of Coa, and Cf−. S. aureus cannot perform hemolysis of red blood cells. This phenotypic characteristic can prevent and control SCM in PE goats. Several antibiotics such as ERYTHRO, AMP, PEN-G, and SULFA were no longer effective for treating SCM in PE goats because S. aureus has developed its resistance to these antibiotics.

The practice of buying and selling without perfect use sometimes causes the unclear amount of the goods sold, to cause losses to one of the parties. Semi-organic farming is a form of soil processing and crop cultivation by utilizing fertilizers derived from organic materials and chemical fertilizers in minimal quantities to increase the nutrient content of the soil. Semiorganic farming can be said to be environmentally friendly agriculture because it can reduce the use of chemical fertilizers to above 50%. In addition, the application of semi-organic agriculture is sustainable with government programs in sustainable agricultural development. Semi-organic agriculture is also considered to have economic differences such as production costs, revenues, incomes, and profits and feasibility when compared to inorganic agriculture that has been first applied. Based on this concept, the purpose of this study is 1). Know the difference in production, receiving, and income costs from semi-organic and inorganic, 2). Know the difference in profits and business feasibility of a corporate-based slash and weigh marketing system. The determination of samples using the Non-Propositional Stratified Random Sampling method with the number of samples for semi-organic farmers is as many as 20 samples or respondents and inorganic as well as 20 respondents. Quantitative descriptive data analysis as well as a statistical test (independent sample t-test). Analysis of shallot farming with environmentally friendly technology applied by farmers in Nawungan Bantul showed the profit obtained by farmers per hectare of Rp. 129,720,000 within ±50 days (1 shallot growing season) compared to inorganic systems of Rp. 58,430,000. Production reached 15 tons/ha with an average price of Rp 17,000/kg (how to sell weight) with a total receipt of Rp 125,280,000. The average B/C ratio in shallot farmers harvested in a weighted manner of 1.03, greater than the slash of 0.952. The feasibility of semi-organic (environmentally friendly) shallot farming with marketing using corporate institutional innovation (weigh instead of slash) showed the highest figure of 2.03.

The study was conducted to evaluate the occupancy rate of barn owl nest boxes, the local rat population, and rat damage to rice crops. It was conducted in three locations in Yogyakarta by observing 10 nest boxes per site. Assessment of their occupancy was monitored by barn owl presence in nest box (egg, chick, and adult) and natural nests in villages nearby. In comparison with control village, the local rat population was observed by the active burrow count method and linear trap barrier systems. Rat damage intensity is estimated by sampling 150 tillers using a stratified sampling approach. The result indicated that 1-4 nest boxes were occupied per location. The owls also nested within buildings nearby. Active burrows ranged from 4 to 25 burrows per 150 m. The rat damage area ranged from 33.33% - 48.57% with 6.33% - 14.86% damage intensity was significantly lower than the control site. Artif...

Even though vegetative planting has been carried out using tubers in rice fields and dry land in Indonesia, not much has been done on sandy land. Another research gap also presents from the considerably low actual productivity (10-15 t ha-1) that still can be doubled (>20-30 t ha-1) in sandy land. The study used three varieties (Lokananta, Bima, and Trisula) and carried out in three stages: characterization and identification of soil biophysical properties, an in-site study of the seed nursery system of TSS, and an assessment of cultivation development based on plant populations increasing production. This study resulted in TSS productivity 30.66-236.00% higher than average national productivity for all three varieties; this is a novel finding. TSS productivity on sandy land ranging from 14.831 to 28.178 t ha-1 was above the national average production at 10.48 t ha-1 of bulb-seed originated shallots. Thus, this result indicates that TSS seed planting system is more profitable, particularly for shallot seed producers (traders and farmers), aside from saving transportation costs. Another benefit is supporting planning and agronomy development, especially the progress of planting shallot from seeds in Indonesia.
