The rail transport is the one of the leading sectors of the national economy. More than 50% of the employees of the enterprises of the railway complex work under the unfavourable impact of hazardous and dangerous substances and occupational factors. In the literature issues of working conditions and health of employees of railway carrepairing plant are hardly highlighted. The aim of the study is the evaluation of the morbidity rate shaped under the influence of harmful occupational factors for the elaboration of preventive measures. In the work there were used generally accepted methods of hygienic studies, analysis of morbidity rate with temporary disability (TD), according to records of periodic medical examinations, occupational prevalence. The railway car-repairing plant was established to be characterized by the complex of harmful factors of the working environment and labor process: noise, local vibration, industrial aerosols of complex composition, chemicals, low light, hardness of the labor process. The levels of incidence with temporal disability in the studied groups, depending on the work seniority in the harmful labor conditions, significantly decrease with the experience from 5 to 9 years and increase with the experience more than 10 years. Executed in-depth analysis as of the both morbidity rate and TD, as well results of periodic medical examinations of workers of main shops shows that overall indices of the morbidity rate and TD are significantly higher than in the comparison group; levels of the morbidity rate and TD in the observed groups significantly decline depending on the length of service in hazardous working conditions with a length of the experience offrom 5 to 9 years and increase with the increase in the length of experience of 10 years or more. In the structure of morbidity and TD leading positions are occupied by diseases of the respiratory system, musculoskeletal system and connective tissue, circulatory system and digestive system, diseases of the eye and its appendages. The health damage risk coefficients in the studied groups of workers and the average losses of working time due to the morbidity with TD per 1 employee in all shops are higher than those in the comparison group. The level of the occupational morbidity rate is very low. Harmful working conditions contribute to the development of general and occupationally related diseases.

The purpose of research is the assessment of the individual cancer risk (ICR) for workers of the basic occupations in key branches of industry of the Irkutsk region. There was executed the calculation of ICR levels for workers of the basic occupations of the aircraft industry, aluminum smelters and vinyl chloride production plants. The estimation of the exposure for workers was carried out according to long-term time-weighted average concentrations in the air of the working area, for the population - on annual average concentrations in the ambient air. To assess the risk that is not associated with the profession, the dose was calculated for the period of life (70 years). When calculating the toxicant doses in the working area there were used the “standard” indices ofpulmonary ventilation for adults, body weight, the work experience in the contact with carcinogens of 30 years, the number of days in the contact of 240, the duration of the working time 8 or 12 hours (in accordance with the working hours) duration. ICR for the Irkutsk population amounted of 3.08E-04, in Shelekhov - 4.8E-05, Sayansk - 1.1E-05. The amount of risk depends on the content offormaldehyde in all territories and chromium VI in cities of Irkutsk and Shelekhov. ICR for workers of basic occupations of studied plants in dozens of times are higher than for the urban population. Priority carcinogens are: chromium VI, nickel, formaldehyde, silicon dioxide -for the aircraft plant employees; 1,2-dichloretan, vinyl chloride - for the workers of vinyl chloride production plant; benzopyrene - for the aluminum smelter workers.

The dynamics and structure of the occupational morbidity rate in main branches of the industry in the Eastern Siberia for the 2000-2015 (on the example of the Irkutsk region) is presented in this paper. During the observation period there were noted the significant gain in the number of cases of occupational diseases registered in such different branches of industry as Coal and Lignite Mining, ship and aircraft building, and in some other branches (metallurgical production, air transport, pulp production, electric power distribution industry). In the structure of the occupational morbidity leading positions are occupied by diseases associated with the exposure to physical factors, industrial aerosols, physical overload and overexertion of certain organs and systems. The main reasons and factors contributing to the gain of the occupational morbidity rate are the imperfection of technological processes, working places, personal protective equipment and/or their lack, constructive defects of machines and equipment, the violation of safety regulations, regimen of the work and rest, insufficiently high level of medical and preventive maintenance, delayed making of decisions for the rational employment to the workers with the revealed early forms of occupational diseases. There pointed out priority directions of the prevention the implementation of which will allow to decline the level of the occupational morbidity rate. The main directions are the implementation of economically caused mechanisms of the interest in the preservation of workers ’ health; implementation of the regional aimed programs; the introduction of new processes, equipment and mechanisms meeting modern hygienic requirements; the assessment of occupational risk with the creation and implementation of the system of monitoring for the dynamics of working conditions and the state of the workers ’ health for the making corrective management solutions on the optimization and elevation of the efficacy and relevance of developed and implemented preventive health measures.

Published: November 2019

Currently the problem of the impact of nanoparticles and nanomaterials on human health remains to be poorly understood. As in our studies of the impact of silver nanoparticles on rats liver as well in works of other researchers there were investigated morphofunctional indices under peroral exposure. Although all researchers took different sizes, doses and concentrations of silver nanoparticles, various exposure time and different stabilizers, the same effects had been obtained, which, however, were occurred under both different doses and time of exposure. However, it was interesting to compare the impact of silver nanoparticles with reference substance - silver sulfate on the mice liver with the previously evaluated effect produced on the rats ’ liver. By ourselves there was executed the morphological comparative evaluation of in vivo oral 2-weeks exposure of 4 concentrations (0.1; 5; 50 and 500 mg/l) of silver nanoparticles with size of 14 nm, stable arabian gum 1:7 by weight, and of 4 similar concentrations of silver sulfate on the liver of male mice СВАхС57В1/6 weighing 25-35g. 2 groups were considered as control: intact mice and mice received gum in water. Results of the exposure were assessed according to 10 morphological and functional indices. The impact of nanosilver was shown to initiate from its concentration of 50 mg/l and to express in the gain of the index of alteration of the cytoplasm of hepatocytes with the increasing in both severity of steatosis and the number of micronecroses, persisting at the same level at concentrations of 500 mg/l and with the elevation of the index of alteration of nuclei of hepatocytes, while the similar effect develops under the influence of silver sulfate at a concentration of 500 mg/l only. The remaining investigated morphofunctional indices did not differ significantly in all groups of mice. Unlike previously executed studies on rats, mice appeared to be sensitive to the effects of nano-silver more than to silver sulfate.

Authors: Abdullah Abdullah , Twinasty Rina , Rohman Taufiqur
Published: November 2019

Humic acid is a compound of colloidal,amorphous, and complex aromatic polymerwith functional groups of -COOH (carboxyl), -OH (phenol), and C = O (carbonyl). The presence of these functional groups provides a rationale for assuming that humic acids have a potential to produce phenolic, carboxylic and carbonylic compounds through cracking process. In this study the cracking was done by isolating humic acids from peat soil, and facilitated by a clay catalyst which had been activated. Humic acids were isolated by extracting the acids from the peat with NaOH and HCl. The characterization of humic acids included the determination of the ash content by gravimetric method and the analysis of the functional groups of humic acids by Infrared spectrometer (FTIR). The clay to be activated was shaped into two forms, pellets and 20-40 mesh granules. The clay was activated by immersing it in HCl and NH4NO3, and then calcined. The characterization of catalysts included the determination of acidity and the Si/Al ratio gravimetrically, as well as the analysis of the pore volume, maximum pore radius, surface area and average pore radius by Surface Area Analyzer NOVA-1000. Humic acid cracking was performed by a fixed-bed reactor system at a temperature of 400°C. The Liquid smoke, the product of cracking, was analyzed by GC and GC-MS to determine the number of compounds and major compounds contained in the liquid smoke. The results show that the isolated humic acid had ash content of 9.10%. Activated clay had acidity and Si/Al ratio higher than the clay before actifated. Based on the analyses of GC and GC-MS it can be found out that the major compounds contained in liquid smoke, the product of humic acid cracking with 20-40 mesh catalyst at a temperature of 400°C were phenolic compounds (74.56%), and no carboxylic and carbonylic compounds as the major compounds. The activated clay can be used as the catalyst for humic acid cracking.
AGRIBUSINESS INNOVATION IN FRESHWATER SWAMP THROUGH DEVELOPMENT OF ORGANIC RICE
Authors: Fauzi Muhammad
Published: November 2019

In the economy of South Kalimantan, the agricultural sector has a significant growth and plays a role as one of the major contributors to the economic structure. However, in some areas with particular land typology like freshwater swamp; it is not reflected in the level of farmers’ welfare. In reality, many farming households in freshwater swamp that solely rely on rice farming still live in a poor condition because of low income. It is therefore necessary to find the alternative solutions through agribusiness innovation. Until now freshwater swamp is always identified with non-organic rice or conventional freshwater swamp rice; Alabio livestock, Alabio potato and Swamp buffalo. The purpose of this study was to analyze the potency of freshwater swamp for the welfare of farmers through agribusiness innovation in addition to oil palm plantations. The study was conducted in Teluk Limbung Village, Babirik Subdistrict, Hulu Sungai Utara Regency, by census with 17 farmers as the respondents. The productivity of organic rice in freshwater swamp reached 4.6 tons/ha. The earned income was greater compared to the income when the farmers only grew inorganic rice like what is commonly cultivated by farmers in the swampy lands.

Published: November 2019

Local wisdom in utilizing swamp soil and water to improve the quality of gelam wood in Central Kalimantan becomes an interesting phenomenon. Improving the quality of wood can economize on the use of wood, which in turn preserves the forests in peat swamp lands. Gelam (Melaleuca sp.) woods that are mostly found in peat swamp forests can be used as piles/stakes in swamp soil, and they are durable for decades. The general objective of this study was to provide a scientific explanation of the effect of peat swamp soil and water on improving the quality of gelam wood either in barked and barkless conditions. This study was conducted by taking gelam trees that grew in Central Kalimantan. It was carried out for 18 months, and investigated the barked/barkless woods, media (swamp water, freshwater, peat swamp soil, and sandy soil) and 3 lengths of burying times. Wood properties analyzed were physical and mechanical properties. The standard of physical-mechanical property tests referred to British Standard 373.
The results showed that the interaction between bark factor (A) and media (B) affected specific gravity. Barked wood produced the highest spesific gravity in swamp water medium. Water media (swamp and fresh water) improved the wood’s specific gravity more than soil media (swamp and sandy soil). The highest values of hardness, stress on Proportional Limit, and Modulus of Elasticity were in the medium of swamp soil. The improvement of the quality of gelam woods, which were either buried or used as stakes/piles, was allegedly resulted from the swamp water infiltrating into gelam woods that thereby increased the specific gravity.

Published: November 2019

This research projected the citizens and water demand in 13 regencies/cities in South Kalimantan Province from 2013 to the next 20 years. The results of the project were compared with the intake capacity to meet the demand in upcoming years. In projecting the population growth, five methods were used, namely aritmethic method, geometric method, linier regression method, exponential method and logarithmic method. The most appropriate method for projecting the population growth is the method which has the minimum value of standard deviation and the correlation value close to 1. Water demand was calculated based on some factors, such as the average water demand, the maximum level of water demand, and the water demand at peak hours. The existing intake capacity was then compared with the water demand projection. In almost all PDAM (Munipical Tap Water Company) observed, the capacity of water processing installation could not fullfill the water demand at the peak hours. The adequate intake capacity of PDAM was only in Balangan regency and Banjarmasin city.

This study aimed to (1) find out the water quality parameters of the river where the common carp cage cultures are located at Murung Raya Regency, either adjacent or far from the gold mine site, including water temperatures, pH, dissolved oxygen, carbon dioxide, ammonia and water clarity; (2) to compare the common carp cage culture profits in the river either adjacent or far from the gold mine sites; and (3) to determine the common carp cage culture development strategies at Murung Raya Regency. This study was carried out in Murung Raya Regency, Central Kalimantan, with the common carp cage farmers at Muara Supoi and Muara Bumban Villages, Murung Regency as the object. The collected data were primary and secondary data. The data analysis used were descriptive analysis, t statistical test, and a SWOT analysis. The results of the study showed that condition of the water where the common carp cage cultures are located at Murung Raya Regency, either adjacent or far from the gold mine sites, still in the range of the quality standards required, namely the temperature of 29.73 - 29.78oC; water clarity of 10 - 11 cm; pH of 6.58 - 6.65; dissolved oxygen of 6.11 - 6.73 mg /l; carbon dioxide of 0.02 - 0.03 mg/l; and ammonia of 0.02 mg/l, so that the common carp cage culture activities at Murung Raya Regency were still very feasible to carried on. The average profits of the common carp cage cultures, either adjacent or far from the gold mine sites, were relatively similar, with the t statistical test result showed that the profits at both locations did not differ significantly at 95% test level. The development strategy of common carp cage cultures at Murung Raya Regency was in quadrant II or S - T, namely utilizing the strengths to overcome the threats. It was implemented by establishing two alternative solutions, namely (1) by taking advantage from the fish culture development programs and supports by the government; and (2) optimized the development function of the of seed center for supplying the high-quality seeds. One of them was by utilizing the special allocation fund (Dana Alokasi Khusus - DAK) from the Ministry of Marine Affairs and Fisheries.

Peatland fires in 2015 that hit 23 of 33 provinces in Indonesia is one of the worst fires in history. South Kalimantan is one of the 23 provinces with the burned land area of 19.179,9 hectares. Peatland burning in Banjarbaru and of Banjar Regency which totaled 1.536 fire point burning with a land area of approximately 1.500 hectares. The main factor of this land fires is of decreased water level in the peat land. Therefore, to overcome that fires will not happen again by creating a conservation pond to hold water, especially during the rainy season in order to keep moist peat.   The planning an peat land conservation in this area of 900 hectares. Peat ecosystem restoration can be done through the realignment of hydrological function where peat dome as a long-term water storage. The purpose of the research is to knowing the state of the physical properties soil for conservation pond made and knowing the condition of the ground water level in the field.  From the results of an investigation soil physical properties obtained peat has not undergone recast and the number of pores in the soil are very large so that the soil becomes porous with a high water level conditions.
AN ANALYSIS ON FISHERY CAPTURE LICENSING TOWARD THE REGISTRATION AND MARKING OF FISH-TRANSPORTING VESSELS WITHIN THE SOUTH KALIMANTAN PROVINCE AUTHORITY
Authors: Amalia Siti Dian
Published: November 2019

This study aimed to (1) identify the distribution of fish-transporting vessels under the authority of South Kalimantan Province; (2) to analyze the causes of unregistered and unmarked fish-transporting vessels within the provincial authority; and (3) to analyze the causes of fishery capture licensing that continues to run without a Fishing Vessel Book (Buku Kapal Perikanan – BKP). This research activity was conducted at the Banjarmasin Fishing Port, Pelambuan Village, Banjarmasin Barat District, Banjarmasin City, South Kalimantan, with the fish-transporting vessel’s owners within the South Kalimantan authority as the research object. The data collected were the data sourced directly from the observation result in the research location, and other supporting data related to the research object. The results showed that the spreading of fish-transporting vessels that land their cargo at the Banjarmasin Fishing Port were found in Kotabaru Regency, Tanah Bumbu Regency, Tanah Laut Regency, Banjar Regency, Barito Kuala Regency, and Banjarmasin City. Based on the data, there are 183 fish-transporting vessels within South Kalimantan Province authority, but only 42 vessels or 23% ships that are registered as fishing vessels.  While for the marking of the vessels, 100% have not carried out marking as fishing vessels.  This is due to the unavailability of a standard BKP and the lack of understanding from the vessel owners. The Licensing of Fishery Capture in the form of SIUP and SIKPI is still issued by BPTSP using only recommendation from Department of Fisheries and Maritime Affairs of South Kalimantan Province.  The registration and marking of fish-transporting vessels of South Kalimantan Province Authority are not optimal due to the unavailability of a standard BKP that can be used as collateral so that a policy is needed from the local government in terms of budgeting funds for the procurement of BKP so that fish-transporting vessels in South Kalimantan Province can be registered and marked as Indonesian fishing vessels.

Immersive virtual reality technology enables the experience of feeling ‘presence’, that is, to have the feeling of being in an immersive computer-supported room. Because these technologies are used increasingly in private households, retailers are very interested in using them as a new sales opportunity. In our experimental study we investigated whether VR-based online shops could be more profitable for them compared to conventional online shops. The following results were found: A VR-based online shop generated a more real perception of the objects, and more interest in buying them. In addition, the shopping experience in the VR-based online shop was perceived as very exciting. However, the amount of acquired knowledge and the influence on the attitude of the buyer seemed to depend on the object type. Despite the limitations of this experimental study due to its focus on internal validity, the results point to the potential of immersive VR-based online shops as a new distribution channel.
