Abstract
Sandalwood, one of the most economic-endangered species, was the origin to the south-eastern islands of Indonesia, but is recently existed as new landraces in several community forests in Gunung Sewu Geopark, Indonesia. All of landraces consisted of three floral variants (YBF, refers to “yellow big flower”; RBF, “red big flower”; and RSF, “red small flower”, respectively). Our previous findings reported differences on floral structures among variants. In this study we further analyzed these variants differences and its consequence on pollination events, among four landraces represented each geographical zone in Gunung Sewu Geopark, in the 2016 flowering periods. The flowering traits of each variant and landrace were measured. Floral visitors diversity, visitation rate and pollination behaviour were observed in each of population and floral variants. Results showed that flower abundance, visitor diversity and visitor abundance varied with sites but were similar among floral variants. Flowers abundance was strongly correlated to the pollinator visitation rate. Visitors diversity varied with sites due to the differences on flower abundance, environmental condition and altitude. The cooler and wetter site was visited more by Dipterans and Hymenopterans. The warmer, drier and lower sites were visited more by Lepidopterans and Dipterans. Sites with fewer flowers received less visitor diversity and abundance. Visitors preference to a given floral variant might be attributed to the differences on floral structures, sizes and colors. Lepidopterans belong to the moth groups (Arctiidae, Hesperiidae and Noctuiidae) preferred to visit the yellow flowers of YBF variant, while those belong to the butterflies groups (Papillionidae, Nymphalidae and Pieridae) preferred the red flowers of RBF and RSF. All six families of Hymenopterans preferred to visit the red flowers with bigger size, RBF. In contrast, all four families of Coleopterans, as well as the four families of Hemipterans, preferred the yellow flowers of YBF. All four families of Dipterans made similar visits to both RBF and YBF which have bigger flowers, while the visitation was less in RSF.

Abstract
The target of the Government of Indonesia (the GoI) for achieving soybean self-sufficiency in 2018-2020 makes some efforts for increasing soybean production requiring the increase of productivity, as well as harvest area, should be done. The rainfed area is an excellent potential for soybean cultivation area expansion in Indonesia. The area reaches 3.1 million ha in Indonesia with 413,000 ha are in South Sulawesi Province. It mostly does not use for soybean cultivation due to limited water availability. Cropping patterns in the rainfed area are paddy - fallow, paddy - corn, paddy - soybean, or paddy - mungbean depends on the water availability. The productivity of soybean in the rainfed area is around 1.5 t/ha, and it is expected to be increased in the range of 1.8-3.2 t/ha. Dissemination of biofertilizer technology for soybean in the rainfed area named “Biodetas” was conducted during the dry season of 2017 in Tompobulu Sub-district, Maros Regency, South Sulawesi Province. Components of “Biodetas” technology introduced include (1) the use of biofertilizer (Agrisoy), (2) the reducing of NPK fertilizer use, (3) the use of leaf fertilizer, as well as (4) the use of organic fertilizer. The dissemination scale was 40 ha then compared to 5 ha of the existing cultivation. Research aimed to determine factors affecting farmers to adopt the biofertilizer technology of “Biodetas”. Research used regression analyses using a binary logic model with the IBM SPSS Statistics 20 program. Variables used were farmers’ experience on soybean cultivation, formal education, the extent of soybean planting area, soybean production, income from soybean, rice, and other farming activities, as well as dummy variables for land ownership status, biofertilizer production inputs access, improved seed access, and higher production cost should be provided by farmers. The application of “Biodetas” was able to increase soybean yield to 2.7 t/ha, 71% higher compared to the existing technology that produced 1.6 t/ha soybean. It is economically feasible to be adopted by farmers with B/C ratio1.2. The determinant of technology adoption by farmers was the extent of the soybean planting area. The larger soybean planting area will accelerate the adoption of technology. It may be related to landowners’ economic capability to provide the necessary production inputs to obtain the optimal yield.

General issues of assessing the reliability of roads
Authors: Bazhanov A P 
Published: November 2019

Abstract
The article describes the reasons for the interest in the problem of ensuring the reliability of roads, which consists in the fact that the maintenance of life safety of the population, material values and social conditions depend on their uninterrupted functioning. The author outlines a modern approach to the analysis of the state of the road pavement in terms of the rate (risk) of destruction and the actual duration of its service. The work substantiates the close connection between the failure of a road and the loss of working capacity or any of its structural elements (roadbed, pavement, road surface) failure. The necessity of improving the method of assessing the safety margin of the integrated ‘pavement - roadbed’ construction is associated with ensuring the reliability of this design, i.e. in terms of the occurrence of its failures. The problems of ensuring the operational reliability of the main structural elements of the road: the roadbed and pavement covering a wide range of issues. This should extend from the application of the theory of reliability and mathematical statistics to analyzing the influence of climatic and operating conditions on the work of the roadbed, improving the assessment of pavement, quality control of materials and justification of rational technology of work. It is shown that for the use in the design process of roads during the development of their pre-design, design and working documentation the authors proposed in this paper a probabilistic-statistical approach to assessing the reliability of roads and the risk of destruction of their pavement over time during road maintenance. This will contribute significantly to adjustment of these indicators in the direction of their improvement.

Published: November 2019

Abstract
This article analyzes advantages and disadvantages of the methods approved at the legislative level and methods developed by various researchers. To identify advantages and disadvantages of each method, an experiment were carried out. During the experiment, safety of the 796 km section of the federal road R255 was assessed. Based on the analysis, all the methods were divided into three large groups: statistical methods, probabilistic methods, and methods based on the analysis of car movement on the road section under consideration. All the accident analysis methods applied in Russia and approved at the legislative level assess road safety when the accident has already occurred, i.e. post-factum. In this regard, it is relevant to identify patterns between the characteristics of the road section, vehicle movement parameters and road accident probability. Using these patterns, road safety can be improved.
The task of determining the matching of actual and planned operation plans in a dispatch control system of the road transport
Authors: Fadeev A I 
Published: November 2019

Abstract
The article deals with the task of determining the matching between actual and planned operation plans in a dispatch control system of the road transport. The actual route of movement along the transport network is recorded as navigation data in the form of an ordered point set which had been passed through: control points identifiers and time stamps for both arrival and departure times. A new approach is proposed to determining the matching between planned and actual movement routes, which is considered as required for the dispatch control system of the road transport. Determining the matching between actual and planned movement routes is proposed to consider as the task of finding the longest common subsequence of two ordered sets: points of the planned and actual movement routes. In this way, the problem under consideration is scaled down to the classical dynamic programming problem — finding the longest common subsequence of several rows. Based on that the article presents a developed algorithm for solving the problem of finding the longest common subsequence of planned and actual movement route points.

Published: November 2019

Abstract
The article describes the mathematical apparatus classifying the movement of the sprung and unsprung vehicle masses in space, as well as the processes of interaction of its elastic tires with the road support surface when driving under the influence of lateral force. The results of calculations of the mathematical model allow one to scientifically justify the test modes and diagnostic parameters of the over-the-road method of monitoring the technical condition of shock absorbers. The normalized values of the found diagnostic parameters are proposed as criteria for assessing the vehicle stability when moving under the influence of lateral force and varying the technical condition of the shock absorbers.
