Published: May 2018

Jember regency has several areas that are morphology of folding hills and mountain folds. The part of landslide prone zone is closely related to the slope of the slope. Areas with a sloping slope of more than 15º need attention to the possibility of a landslide disaster. Interconnection contacts with weathering of rocks, settlements and land cover also affect the landslide potential. The existence of Ijen Volcano that produces volcanic rock deposits that are generally not yet unified will increase the potential for landslides in Jember Regency. Landslide has occurred one of them on Gunung Gumitir Street which is the main route of Surabaya-Jember-Banyuwangi traffic. In May 2016 this street is hit by landslide, so the flow of traffic through this lane is paralyzed and must be diverted to a further path, which rotates to Situbondo City. The transfer of this pathway resulted in a loss to the local community and who crossed the path.The occurrence of landslide disaster shows that Jember Regency area is vulnerable and potentially return to landslide. Therefore there is a need for a solution to solve this problem. One solution to solve the problem is by utilizing Geographic Information System (GIS) application. The purpose of this research is to analyze zonation prone to landslide in jember district. The design of the research is Geographic Information System overlay analysis. This design combines several parameters in the determination of landslide-prone zones. This design combines several parameters in the determination of landslide-prone zones. The parameter used in this research is (1) land use, (2) topography, and (3) soil.Based on the research results, it can be known zone with highest to lowest vulnerability level. Zone with very high level of vulnerability is located in Panti sub-district, Sumberbaru, Sukorambi, Dyke, Silo and Jelbuk. The zones have similar characteristics that include (1) soil type of andosol, (2) clay texture, (3) uncompacted rock, (4) slope of 30⁰-40⁰ (steep and very steep), and (5) land use for settlements and plantations.

Implementation of an Automatic Checking Machine for Battery Welding Condition
Authors: Wang Kuen-Cheng , Wang Chih-Hung , Chen Tsair-Rong 
Published: May 2018

Abstract
The common automobile battery is composed of series connection of six units of battery chargers, with the tab welded between each battery charger for a purpose of connection. Thus the satisfactory welding point will be closely related to the lifetime of the battery. If the welding point is not solid enough, it will produce high resistance and heat in welding point upon numerous current discharge and charge, thus leading to a breakage of the welding point and causing damage to battery. This essay aims to implement a checking machine for battery welding condition. This machine based on a microprocessor as the core of control by combining a direct current power supply to measure the internal resistance of welding point of the battery so that the condition of the welding point can be judged. Upon the signal of inner resistance goes through an amplifier and then a buffer circuit, this analog signal will be converted into a digital signal and then be conveyed to the microprocessor. Finally, the configuration is displayed by an LED, which also reveals the results of measurement upon the comparison of the signal and a setup value. In the meanwhile the relay contact can be used to notify the PLC of the auto wire to show the condition of the battery, while RS485 or RS232 can be used to link with computer to record the welding condition of the battery.
Trade‐Offs in Cereal Rye Management Strategies Prior to Organically Managed Soybean
Authors: Crowley K. A. , Van Es H. M. , Gómez M. I. , Ryan M. R. 
Published: May 2018

Core Ideas
A field experiment was conducted to compare cereal rye management strategies.
Roller‐crimping cereal rye reduced labor requirements and increased soil health.
Harvesting cereal rye for ryelage maximized profitability.
Spring moisture affects soybean yield in roller‐crimped systems.
Three cereal rye (Secale cereale L.) management strategies for organic soybean [Glycine max (L.) Merr.] production were compared in terms of their agronomic, soil health, and economic benefits. In central New York in 2014–2015 and again in 2015–2016, we compared (i) a “No‐cover” control treatment, in which bare soil was plowed prior to planting soybean, (ii) a “Plow‐down” treatment with cereal rye plowed at jointing stage prior to planting soybean, (iii) a “Ryelage” treatment with cereal rye harvested for forage and plowed prior to planting soybean, and (iv) a “Roll‐down” treatment with cereal rye roller‐crimped prior to no‐till planting soybean. Water infiltration and soil respiration were greater in the Roll‐down treatment compared with the No‐cover treatment; however, weed biomass in soybean was greatest in the Roll‐down treatment. Soybean yield did not differ between treatments in 2015, but yields were lower in the Roll‐down treatment in 2016, which was likely due to dry conditions in May and June. Practices used in the Roll‐down system required the least amount of labor, but harvesting cereal rye for ryelage and then using tillage before growing organic soybean maximized profitability. Our results show soil health improvement, labor reductions, and enhanced profitability from growing cereal rye before organic soybean. However, no single cover crop management strategy provided all of these benefits. More research is needed to better understand the effects of precipitation at different times, and how management can be improved to overcome trade‐offs between strategies.
Tillage and Fertilizer Management Effects on Phosphorus Runoff from Minimal Slope Fields
Authors: Yuan Mingwei , Fernández Fabián G. , Pittelkow Cameron M. , Greer Kristin D. , Schaefer Daniel 
Published: May 2018

Phosphorus fertilization can increase P losses in surface runoff, but limited information is available for fields with <2% slopes in the US Midwest. Our objectives were to determine the effects of tillage–fertilizer placement (no‐till–broadcast, strip till–broadcast; or strip till–deep placement, −15‐cm subsurface band) and fertilizer rate applied in the fall (0, 52, or 90 kg P2O5 ha−1 yr−1) on runoff P concentrations and loads in fields with <2% slopes near Pesotum, IL, during fall and spring simulation runoff events, and to measure corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] grain yield. Across four simulated runoff events, deep placement reduced dissolved reactive P (DRP) loads by 69 to 72% compared with the broadcast treatments. A tillage–fertilizer placement × P rate interaction showed that DRP and total P (TP) concentrations remained low when P was deep placed, regardless of P rate, whereas concentrations increased with increasing P rate for the broadcast treatments, but no differences existed for bioavailable P (BAP) (α = 0.05). At one site, rainfall simulation in the spring versus fall increased runoff volumes but sharply decreased BAP concentrations. During fall runoff simulations, deep placement reduced TP loads, and greater TP loads occurred with the 90‐ than the 52‐kg P2O5 ha−1 yr−1 rate. Similarly, when P was broadcast in the fall, DRP and TP concentrations were greater than deep‐placed P, but no treatment differences occurred in the spring. Deep banding P and K did not reduce crop yield but reduced runoff losses of P from flat fields compared with broadcast P applications, particularly at high rates of P application.Core Ideas
Subsurface‐banded P applications reduced surface P runoff losses in flat fields.
Subsurface‐banded P and K applications maintained grain yields relative to broadcast.
P losses increased with P rate for broadcast, but not for banded P applications.
Fall runoff produced less water but greater P concentrations than the spring.
P fertilizer rates matching crop needs minimized P runoff potential.
Phosphorus Leaching from an Organic and a Mineral Arable Soil in a Rainfall Simulation Study

Published: May 2018

Phosphorus derived from agricultural systems has been found to cause eutrophication of surface waters. To combat this, the specific location of soil profile P release is necessary for development of effective mitigation strategies. This paper describes a P leaching study of two Swedish arable soils, an organic (Typic Haplosaprist) and a mineral soil (Typic Hapludalf), both with high P content. Undisturbed soil columns isolated 0‐ to 20‐, 20‐ to 40‐, 40‐ to 60‐, and 60‐ to 80‐cm depth intervals. These were placed in a rainfall simulator and subjected to four 50‐mm rainfall events to identify the origin of P leachate as a function of soil depth interval and physicochemical properties. Phosphorus losses were greatest from the two uppermost layers of both soils after 200 mm of artificial rainfall was applied at 5 mm h−1. Total P concentration in leachate from the 0‐ to 20‐cm layer ranged from 2.1 to 8.8 mg L−1for the mineral and 3.7 to 10.3 mg L−1from the organic soil, with most (95–100%) in dissolved reactive P form. Degree of P saturation correlated well with total P leaching losses from the organic soil (R= 0.84) but not the mineral soil (R= 0.69), suggesting that the presence of Al and Fe (hydr)oxides has a stronger influence on P leaching in the organic soil. Results indicate that both soils have the potential to contribute concentrations of P above those known to cause eutrophication of surface waters.Core IdeasThe majority of P leached from both soils was from the top 20 cm, in DRP form.Phosphorus concentrations in leachate were higher from the organic than the mineral soil.Degree of P saturation correlated well with P leached from the organic soil.High rainfall application promoted losses of P potentially complexed to DOC and Fe or Al.Both soils leached concentrations of P above those known to cause eutrophication.

AbstractIn the Koto Panjang Dam, Riau there are more than 1582fish floating cages present. Fish feed spilled from the cage is believed to affect the diet of wild endemic fishes inhabit the dam. To understand the effect of the cage on the diet of the endemic, a study has been conducted on May to September 2013. There were 5 sampling sites, 2 sites located in the natural area that there is no cage (St 1Na and St2 Na) and the others (3 Ka, 4 Ka and 5 Ka) were in the area around the cage. Fishes were sampled hourly, for a 24 hour period and their stomach content was analyzed. Results shown that there were 31 species of endemic fishes such as Puntius schwanenfeldii, Macrones nemurus, Hampala bimaculata, Osteochillus hasselti, Rasbora vaillanti, Tynnichtys vaillanti, Ophiocephalus melanosoma, Chela oxygastroides, Cyclocheilichthys heteronema, Notopterus chilata, Puntius bramoidesandCyclocheilichtys apogon. Among these fishes, however, only P. schwanenfeldii that greatly affected by the presence of the aquaculture activities as the stomach of fish living around the cage was filled with fish feed pellets (more than 90%). The fish living in the area with no cage, however, filled with animal and plant remains. This fact indicates that the P. schwanenfeldii is an opportunist fish that is able to change their diet into fish feed pellets. Based on data obtained, it can be concluded that the presence of fish floating cage aquaculture activities affect certain fish species only.Key words: Fish floating cage, Puntius schwanenfeldii, Koto Panjang Dam, endemic fish, fish feed pellet
Off-line robustification of Generalized Predictive Control for uncertain systems
Authors: Khelifi Otmane Khelifa , Bali Nordine , Nezli Lazhari 
Published: May 2018

Abstract
An off-line methodology was proposed for enhancing the robustness of an initial Generalized Predictive Control (GPC) by convex optimization of the Youla parameter. However, this procedure of robustification is restricted with the case of the systems affected only by unstructured uncertainties. This paper proposes an extension of this method to the systems subjected to both unstructured and structured polytopic uncertainties. The main idea consists in adding supplementary constraints to the optimization problem which validates the Lipatov stability condition at each vertex of the polytope. These polytopic uncertainties impose a set of non convex quadratic constraints. The globally optimal solution is found by means of the GloptiPoly3 software. Therefore, this robustification provides stability robustness towards unstructured uncertainties for the nominal system, while guaranteeing stability properties over a specified polytopic domain of uncertainties. Finally, an illustrative example is given

Published: May 2018

Abstract
Austenitization is the first step of heat treatment preceding the isothermal quenching of ductile iron in austempered ductile iron (ADI) manufacturing. Usually, the starting material for the ADI production is ductile iron with more convenient pearlitic matrix. In this paper we present the results of research concerning the austenitizing of ductile iron with ferritic matrix, where all carbon dissolved in austenite must come from graphite nodules. The scope of research includedcarrying out the process of austenitization at 900° Cusing a variable times ranging from 5 to 240minutes,and then observations of the microstructure of the samples after different austenitizing times. These were supplemented with micro-hardness testing. The research showed that the process of saturating austenite with carbon is limited by the rate of dissolution of carbon from nodular graphite precipitates

Abstract
The performed examinations concerning the process of filling the plaster ceramic moulds with aluminium alloys allowed to assess the influence of various methods of introducing the metal into the mould cavity on the macro- and microstructure of the obtained experimental castings. The comparison was performed for castings with graded wall thickness made either of EN AC-44000 alloy or of EN AC-46000 alloy, produced either by gravity casting, or by gravity casting with negative pressure generated around the mould (according to the Vacumetal technology), or by counter-gravity casting. It was found that the silicon crystals grow in size with an increase in wall thickness due to the slower cooling and solidification of castings
Selected Principles of Feeding Systems Design: Simulation vs Industrial Experience
Authors: Perzyk M. , Kochański A. , Mazurek P. , Karczewski K. 
Published: May 2018

Abstract
Simulation software dedicated for design of casting processes is usually tested and calibrated by comparisons of shrinkage defects distribution predicted by the modelling with that observed in real castings produced in a given foundry. However, a large amount of expertise obtained from different foundries, including especially made experiments, is available from literature, in the form of recommendations for design of the rigging systems. This kind of information can be also used for assessment of the simulation predictions. In the present work two parameters used in the design of feeding systems are considered: feeding ranges in horizontal and vertical plates as well as efficiency (yield) of feeders of various shapes. The simulation tests were conducted using especially designed steel and aluminium castings with risers and a commercial FDM based software. It was found that the simulations cannot predict appearance of shrinkage porosity in horizontal and vertical plates of even cross-sections which would mean, that the feeding ranges are practically unlimited. The yield of all types of feeders obtained from the simulations appeared to be much higher than that reported in the literature. It can be concluded that the feeding flow modelling included in the tested software does not reflect phenomena responsible for the feeding processes in real castings properly. Further tests, with different types of software and more fundamental studies on the feeding process modelling would be desirable.
