Abstract
Wanagama’s success in rehabilitating forests with the community is a mutually beneficial relationship between the community and Wanagama. Farmers are allowed to take grass to meet their animal feed needs. Harvesting grass will have an impact on changing the physical and chemical properties of the soil. This research aimed to analyse the soil properties at the grass plantation and at the area of post grass harvesting. Also, aimed to relate the impact of the grass harvesting with sustainable forest management. Soil samples were taken from the field randomly both at the three areas of grass plantation and post harvesting. It is located at the upper, middle, and lower area of a slope with 3 replications. The soil samples then were brought to the laboratory to analyse. The result showed that all of the soil have the texture of clay with the clay content varies from 48.33 to 76.3%. The bulk density and particle density are also various that are 1.09 - 1.55 and 1.8 - 1.99 respectively. Soil porosity ranges from 13.89 to 43.52 % which is considered as moderate. The soil permeability is mostly considered as slow and the soil organic matter content of 3.26 - 7.66 %. In general, grass harvesting does not change the soil properties so, it remains the sustainability of the soil.

Abstract
This study was conducted to study orthopterans biodiversity in the paddy fields of Sleman Regency. This research was conducted on the paddy fields of Sleman which were divided into two lines (Palagan and Cangkringan lines). The variations of altitude are 150-250 masl, 260-350 masl, 360-450 masl, and 460-550 masl. Observations were performed by purposive sampling. The environmental parameters, such as humidity, light intensity, and temperature, were measured. Diversity of orthopteran was analyzed using Shannon - Wiener index (H’) and Evenness index (E’). We found 4.417 individuals which consisted of nineteen species, sixteen genera, and five families. The most dominant species were Oxya japonica, Gesonula mundata, and P. fumosa, while Caryanda spuria, Euconocephalus pallidus, and Paratettix sp. were minor species. The highest diversity and evenness of orthopteran in Palagan line was at P4 (H’=1.836, E’ = 0,678), and in Cangkringan line was at C4 (H’=2.098, E’=0.755). The lowest diversity and evenness of orthopteran in Palagan line was at P2 (H’ = 1.141, E’ = 0.433), and in Cangkringan line was at C2 (H’ = 0.989, E’ = 0.375). Correlation value between altitudes with individuals, diversity, and evenness were -0.069, -0.676, and -0.530, consecutively.

Abstract
Allelochemical based herbicides are environmentally friendly management alternatives. Thus, cosmos (Cosmos sulphureus Cav.) flower extract as a bioherbicide was investigated in soybean productions. This study aimed to determine effective spraying volume of C. sulphureus flower extract to manage weeds based on weed dominances and soybean yield. This research was conducted at Banguntapan Village, Bantul District, Special Region of Yogyakarta Province, Indonesia on August to November 2018. This study was set as a single factor Randomized Complete Block Design (RCBD) with three replications set as blocks. Three spraying volumes; 1000, 2000, 3000 L.ha−1 and two weed management practices were used as control. Continued weed free and weeded treatments were used to determine soybean yield lost. Data were analyzed using Analysis of Variance (ANOVA), continued with Least Significant Differences (LSD) at the 0.05 probability level. Results showed weed species in soybean fields was dominated by purple nutsedge (Cyperus rotundus L.). The 400 g.L−1 extract concentration applied at 3000 L.ha-1 resulted in similar weed control and soybean yield compared to pre-emergence herbicide application and manual weeding at 1 and 3 weeks after planting (WAP). These findings showed that extract of cosmos flowers possess bioherbicidal activity against weed without having detrimental effects on the soybean plants.

Abstract
Water management plays a crucial role in optimizing plant growth and production. The amount of water supplied and the timing of its application are the keys of irrigation management. The right irrigation system will result in optimal crop production and high water use efficiency (WUE). Modeling in DSSAT (Decision Support System for Agrotechnology Transfer) software can simulate the effect of water management on various types of plants. The study in this paper aims to find out the effect of water management systems on soybean in two types of soil with simulation. This study conducted descriptive quantitative methods. Combination between all irrigated systems and Tha tum type soil (AITT000001) obtained the highest yield due to soil texture, loam better than sand on water holding capacity. The highest WUE was reached the automatically irrigation system, both in the Tha Tum and IBSB910015 soil type. It means automatically irrigation system more precise than others.

Abstract
As population size grows over time, staple food production also needs to keep up with increased annual demands. In Indonesia, the agricultural sector applies intensification and extensification to maximize rice productivity. However, farm extensification can instead decline productivity, should it sprawl into marginal lands like the study area that has been affected by sea-level rise impact, i.e., surface saltwater intrusion. Therefore, this study set out to differentiate paddies into segments affected and unaffected by salinity based on discernible variation in rice growth stages. These stages were determined using a vegetation index, NDVI (Normalized Difference Vegetation Index), calculated from time-series Sentinel-2 L2A+B image data from 2015 until 2020. The resulting temporal NDVI showed two cropping patterns year-round but with different planting times. In salinity-unaffected paddy segments, farmers began the inundation-transplanting stage in late March and ended the cropping season with fallow in August. Meanwhile, in salinity-affected segments, the cropping stages were the opposite: inundation in early April and fallow in early September. The measurable impact of salinity was apparent at the vegetative-generative stage, where salinity-affected paddies had the highest NDVI of 0.64–0.65, whereas those unaffected had the highest NDVI of 0.7–0.75. These index values indicate an impaired rice growth rate due to salinity effects. Compared with the field-measured data, the NDVI showed 85% accuracy, with a Kappa coefficient of 0.87. Meanwhile, the NDVI-EC correlation test produced R-values of 63–85%. Overall, this research has confirmed that remote sensing image and technology can acquire variable data that explain salinity effects on coastal paddies.

Abstract
Introduction of Citrumelo and Kanci, an alternative citrus rootstock, into citrus cultivation system in Indonesia as complement of Japansche citroen (JC) is very appreciated. Compatibility of Citrumelo and Fortunella to commercial citrus in Indonesia have not been evaluated. The aim of the study is to assess the compatibility of Rimau Gerga Lebong (RGL) mandarin citrus grafted onto JC, Citrumelo, and Kanci based on anatomical, morphological and physiological parameters. The results showed that 100% of RGL mandarin shoot bud grew on Citrumelo and JC rootstocks, but only 88.75% on Kanci rootstock. Anatomically, RGL mandarin at 60 days after budding (DAB) had perfectly adhered on Citrumelo rootstock and not yet fully adhered on JC and Kanci rootstock. Morphologically, RGL-Citrumelo and RGL-JC combinations at three years old plant resulted in the same plant growth parameters, better than RGL-Kanci combination. Physiologically, RGL-Citrumelo and RGL-JC combinations had the same chlorophyll index, better than RGL-Kanci combination. RGL-Citrumelo and RGL-JC combinations showed graft compatible and RGL-Kanci combination showed late incompatibility.

Abstract
Character improvement of citrus could be done by mutation breeding in which one of the purposes is to obtain seedless fruit. One of the mechanisms of seedlessness is through low viability and germination rate of pollen. This study was aimed to know the behavior of pollen of Mutant SoE Mandarin and its effect on seedless character of the fruit. The research was done in 2015-2016 in Laboratory of ICSFRI. Plant materials used were flowers derived from Mutant plants of SoE Mandarin, which were grown from irradiated budwoods of SoE Mandarin. The irradiated buds were grafted onto 6 months-old rootstocks of Japanese Citroen and maintained in pots in Tlekung Experimental Field ICSFRI. For controls, flowers from local Mandarin (SoE and Batu 55) varieties which were available during the study were used. The pollen were observed on the viability using acetocarmine 1% and successful pollination of flowers. The result showed that there was clearly different pollen viability of the mutant and control plants hence the different seed numbers. Mutant SoE has 36.7% viability and average number of seeds of 2.3 while SoE Mandarin has 98.94% viability and average number of seeds of 11.6. Observation on pollination showed that most pollens were arrested on stigma and less or no pollen found in ovaries of both self-pollinated flowers of Mutant SoE and cross-pollinated flowers of Mutant SoE x Batu 55. This assumed to be the reason of the low number of seeds on mutant fruits.

Published: March 2021

Abstract
In order to be used in feeding farm animals, perennial cereal grasses are widely cultivated in various soil and climatic zones of the Russian Federation. They are one of the most important sources of raw materials for the production of various types of feed (hay, haylage, silage, grass meal, briquettes and pellets). The grasses harvested in the booting phase (prior to sweeping, hatching) are distinguished by high fodder advantages, good technological properties, and a significant content of basic nutrients. The dry matter of grasses in terms of the yield of feed units is almost as good as that of oat grain. This article presents the results of studying various types of cereal grasses. The most drought-resistant and productive variety of perennial cereal grasses has been identified with the aim of cultivating it in an arid region to create long-term pastures and hayfields resistant to grazing of farm animals.

AbstractThe wood of 22 of the most common low resinous tree species were studied. The number of polyphenols in the wood of the studied species ranges from 23.6 to 1433.1 mg% (0.02-1.43%). The maximum number is noted in the wood of thorny blackthorn. As the wood of fruit species ages (over 3 years old), the content of polyphenols decreases. The content of organic acids in wood of tree species varied in the range of 0.21-1.08%. The leader in terms of their content was the common rowan tree. The amount of tannins and dyes in wood species ranged from 1.45 to 26.5% and was maximum in the tissues of thorny blackthorn. The tannin level in the tissues of the tree species was 0.83-20.8%. The highest tannin content was in the wood of the rowan tree. With the natural drying of wood of 20 species within 8 months in a ventilated room at an air temperature of 25° C, the moisture content of the wood decreases 1.4-3.83 times and is set at the level of hygroscopicity (11.47-35.6%). In the process of slow drying of wood species, organic acids are not destroyed in them, but are concentrated. The least hygroscopic is the wood of the walnut and pedunculate oak, the most hygroscopic is the wood of the heart-shaped linden.

Abstract
The article presents a mechanism for analyzing the costs of the process from the point of view of assessing the effectiveness of the functioning of the quality management system at mechanical engineering enterprises of repair profile. The analysis of the costs of the process can be carried out in four directions: analysis of the effectiveness and efficiency of the process, analysis by type of costs, analysis of the effectiveness of measures to improve the process, comparison of the amount of costs for compliance and losses from non-compliance with the main economic indicators of the economic activity of the enterprise. Each direction can be applied independently, but in order to achieve reliable results and optimize the cost of quality, it is necessary to analyze the cost of quality in the four proposed directions. We analyzed the costs of repairing KAMAZ engines in four directions and came to the following conclusion: the introduction of a process cost management system allows us to timely identify process inconsistencies and take measures to eliminate them and reduce the risk of occurrence in the future, it is necessary to increase the amount of preventive costs in order to shift the break-even point right, it is necessary to take measures that actually prevent the occurrence of possible problems, the costs of compliance and losses from inconsistencies in sales are significant, therefore, measures should be taken to identify, analyze and assess the risk of inconsistencies in production and corrective actions to reduce the share of costs in total sales volume.

Published: March 2021

Abstract
The choice of the region for the location of the production of ecologically pure food is substantiated, taking into account the results of the complex ecological zoning of Russia. Research shows that the Altai Territory has the necessary prerequisites for the transition to an environmentally oriented development of food production. The factors for the development of food production have been taken into account and grouped, which make it possible to reveal the potential for greening the regional agro-industrial complex. The ecological and economic conditions and the resource potential of the region determine the expediency of searching for the type of firms of the corresponding specialization. The working hypothesis is that the production of organic food is justified by two types of agricultural and processing organizations (newly created, low-profit or unprofitable). The application of the decomposition method made it possible to determine the basic development strategies of two types of organizations, taking into account the phases of the life cycle of the production of environmentally friendly food.
