Indonesia has extensive upland acid soils, which is around 99.6 million hectares spread across Sumatera, Kalimantan and Papua Islands. The use of upland acid soils for food crops is an urgent need because of the government's self-sufficiency target, including corn. The level of nutrient in upland acid soils is relatively low so it requires adequate input of ameliorant, inorganic and organic fertilizers to produce high corn yield. A demonstration farm of corn based on the direct application of reactive phosphate rock (RPR) fertilizer was carried out in rainy season 2018/2019 by involving three farmer groups as cooperative farmers, with an area of 50 ha in Margosari village, Metrokibang subdistrict, Lampung Timur Regency. This paper presents the results of financial analysis of corn farming at the demonstration farm area. Data was gathered from 52 farmers (43.7% of the cooperative farmers) which randomly selected as survey respondents. The results of the analysis showed that balanced fertilization using RPR as much as 1 t ha −1 as a source of P fertilizer was financially benefited to farmers. The average corn productivity of hybrid varieties reached 14.357 t ha −1 and it gave an R/C ratio of 1.8.

This study aims to identify the antimicrobial properties found in andaliman and test to the shelf life of beef nuggets containing andaliman. This study method uses an exploratory method which begins with andaliman extraction and identification of antibacterial compounds. The next stage is the manufacture of beef nuggets that are treated (0; 0.5; 1; 1.5) % andaliman. The observed research parameters included: phytochemical test and contamination test (microbiology). This study uses Factorial 4x3 Completely Randomized Design (CRD) with 2 factors: factor 1: andaliman concentration and factor 2: shelf life. The result showed that Andaliman has antimicrobial properties. The 1.5% Andaliman concentration in beef nuggets (N3H0) has the best inhibitory power, because the andaliman beef nugget has the highest inhibitor when compared with other treatment.

Microbial oil production has many advantages such as rapid proliferation of microbial cells and short production cycle. The raw materials needed for growth are abundant and inexpensive such as starch, sugar, especially the waste which can be utilized in food or paper industry. 170 oil-producing strains were screened by Sudan black staining observation using fat grains as screening index, among which, 6 high lipid yield yeast strains were identified by residual sugar as indirect index. By comparing the oil-producing ability of this strain, it was determined that the first strain was a good strain for oil production by fermentation. The biomass, oil content and oil yield of the strain were 11.58 g/L, 36.68%, 4.25 g/L, respectively. Through analysis on 26S rDNA sequence and observation on morphological characteristics, culture characteristics and physiological and biochemical characteristics, this strain belonged to Cryptococcus spp.

Living close to the dangers of volcanoes has become a descending culture in Indonesia, especially for people living around Merapi Volcano. The sister school program is implemented as one of the strategies to reduce the risk of volcanic disasters in the region. The purpose of this study was to examine the perception of the school community towards the sister school program at Merapi (The Case Study of Glagaharjo Elementary School and Bronggang Elementary School, Sleman Regency, Special Region of Yogyakarta, Indonesia). This research is quantitative-qualitative research. Data collection was carried out through in-depth interviews with the school principals in affected schools and supporting schools. In addition, interviews were conducted to all teachers and sufficient representatives of students in both schools. The results showed that principals and teachers in the affected schools and buffer schools agreed with the organization of the sister school, but still needed some improvements in the implementation. Furthermore, 91% of students in schools were affected and 90% of students at the buffer school also agreed with the sister school program.

The methodical basis for evaluating the effectiveness of state support in domestic agriculture is the assessment by the criterion of effectiveness. It is the methodical approach used in assessing the development of the constituent entities of the Russian Federation, municipalities, the effectiveness of implementing the federal, regional, and sectoral programs and strategies. Efficiency, defined as the achievement of certain indicators of stated or planned goals, as the solution of tasks in accordance with certain indicators, is assessed by the index method. In this case, it is not the absolute or relative change of the result that is assessed but the level of its achievement. The use of performance makes it difficult to assess the level of innovation activity. The continuing growth in state support for crop production in the context of budget deficits, the entry of the Russian Federation into the World Trade Organization, and the need to increase the innovative activity of the industry require the justification of any financial decisions, including those implemented in the form of subsidies. The rationale should serve as a methodology for assessing the effectiveness of subsidies, which is based on the use of the criterion "result" and not its "effectiveness". The development of a methodical approach to evaluating the effectiveness of subsidies as a mechanism for increasing the innovative activity of crop production can make the assessment procedure more transparent, consistent with international assessment criteria, replacing performance indicators in the Subsidy Agreements with planned results and volumes and types of spending. The use of a methodical approach will lead to a reduction in the volumes of inefficient and unjustified budget expenditures, providing an additional impetus for increasing innovation activity in the crop production sector of the Pskov region.

Waste materials resulting from the grain processing industries are harmless and easily amenable to enzymatic and microbial bioconversions. Basidiomycetous mushrooms grown in vitro are promising producers of protein and essential amino acids. Mushroom biomass production under appropriate cultivation conditions using agricultural by-products is a cheap and affordable way to obtain a high-quality food product. The present work explores the possibility of using grain wastes for the cultivation of golden oyster mushrooms under deep cultivation conditions. For these purposes, cornmeal was used as a source of carbon waste and gluten as a source of nitrogen. A high substrate colonization rate was observed. The fruiting cycle lasted about 26 to 28 days on the studied substrates. The most prolonged cycles were obtained on the medium supplemented with sawdust. The maximum and the minimum yields were obtained on wheat straw substrate (171.2 g per kg of substrate) and a grain waste substrate (113.4 g per kg) respectively. On birch sawdust subtrate and on a substrate of grain waste and birch sawdust mixture, the yields reached 143.2 g and 130.3 g in this order. The average yielding crop attained 113.4 g of fresh mushrooms grown on 1 kg of substrate under a relative humidity of 70-75%. This promising work stream not only proposes a waste disposal method, but also, a significant source of income for the grain processing enterprises.
