Authors: Ardhitama Aristya , Sholihah Rias 
Published: December 2018

IntisariDaerah Riau termasuk kedalam wilayah ZOM (Zona Musim) dan Non ZOM. Daerah Non ZOM merupakan daerah-daerah yang tidak mempunyai batas yang jelas secara klimatologis antara periode musim hujan dan musim kemarau. Propinsi Riau memiliki wilayah Non ZOM 14 yang menurut teori tidak memilki perbedaan musim hujan dan musim kemarau. Dalam kajian penelitian ini penulis ingin membuktikan bahwa daerah Non ZOM 14 terdapat musim hujan dan musim kemarau. Data yang digunakan adalah data curah hujan (CH) dan hari hujan (HH) dasarian yang diambil dari stasiun daerah Dumai dan Sungai Pakning untuk menentukan Awal Musim. Dari hasil penelitian yang didapatkan daerah Non Zom 14 memiliki pola musim hujan dan musim kemarau yaitu awal musim kemarau yang pertama jatuh pada dasarian bulan Feb I sampai Feb III dan terjadi kembali pada bulan Mei II sampai bulan Juli II diperoleh hari hujan sebesar ≤ 2(HH) dengan nilai CH sebesar <30 mm. Awal musim hujan yang pertama terjadi pada dasarian pada bulan Maret I sampai bulai Mei II, kemudian musim hujan kembali terjadi pada bulan Juli II sampai bulan Desember II yang diperoleh dari hari hujan ≥ 4 (HH) dengan batas CH sebesar >50mm diperoleh besar jumlah CH ≥ 100mm. Sehingga dapat disimpulkan untuk daerah Non ZOM 14 Riau dapat direkomendasikan menjadi daerah ZOM (Zona Musim). AbstractRiau area included into the territory of ZOM (Season Zone) and Non ZOM. The Non ZOMS were areas that do not have a clear limit for climatologist between the period of rainy season and dry season. Riau Province has an area of 14 which according to Non ZOMS theory do not have differences in rainy season and dry season. In this research studies the author want to prove that the Non ZOMS 14 there is a rainy season and a dry season. The data used are the precipitation data (CH) and rainy day (HH) decade taken from local station in Dumai and Sungai Pakning to determine the start of the season. From the results obtained by research area Non Zoms 14 has the pattern of rainy season and dry season is the beginning of the dry season the first fell on the decade month of Feb I until Feb III and going back in May II until July II obtained a rainy day at ≤ 2 (HH) with CH value < 30 mm. the Beginning of the rainy season the first one occurred at decade in March I until May II, later rainy season occurred in july II until december II obtained from rainy days ≥ 4 (HH) with limits of CH > gained an enormous amount of CH 50 mm ≥ 100 mm. so it can be inferred for the Non ZOMS 14 Riau can be recommended to be ZOMS (zone seasons).
PENENTUAN DISTRIBUSI TIPE AWAN DI PROVINSI RIAU MENGGUNAKAN CITRA SATELIT MTSAT IR1
Authors: Dewi Saraswati 
Published: December 2018

IntisariPenentuan distribusi tipe awan berdasarkan diagram temperatur kecerahan (TBB) – perbedaan TBB dilakukan dengan menggunakan data citra satelit MTSAT IR1 dan IR2 pada bulan Januari dan Maret 2014 di 4 (empat) titik kajian di Provinsi Riau. Terdapat 6 (enam) tipe awan yang dikategorikan dalam diagram TBB-DT antara lain awan dingin dengan ketebalan optik besar (tipe awan Cumulonimbus/Cb), awan hangat dengan ketebalan optik besar (tipe awan Cumulus/Cu atau Stratocumulus/Sc), awan dingin dengan ketebalan optik kecil (tipe awan Cirrus/Ci yang cukup padat atau dense), awan hangat dengan ketebalan optik kecil (tipe awan Ci), serta awan tipe N yang merupakan tipe awan tipis di level rendah. Dari seluruh data yang ada dalam pada bulan Januari 2014 dan Maret 2014, distribusi awan di daerah kajian didominasi oleh tipe awan Cirrus (Ci tipis, Ci tebal, dan Ci solid). Karakteristik wilayah Riau yang cenderung kering di bulan Januari maupun Maret 2014 mempengaruhi pertumbuhan awan di daerah tersebut dan kondisi cuaca didominasi oleh cuaca cerah. Dari perbandingan yang dilakukan antara hujan dengan tipe awan di 4 (empat) titik kajian, penentuan jenis awan penghasil hujan tidak dapat dilakukan hanya dengan mengambil data TRMM dan data TBB di suatu titik karena tidak menunjukkan adanya hubungan antara hujan dengan tipe awannya. Hujan yang jatuh di titik kajian bisa jadi tidak berasal dari awan yang berada tepat di atasnya karena faktor angin.Abstract Determination of cloud type distribution based on the brightness temperature (TBB) – temperature differential image (DT) has been done using MTSAT IR1 and IR2 image data on January and March 2014 at 4 (four) point studies. There are 6 (six) cloud types categorized by the TBB-DT diagram: optically thick cold cloud (Cb type), optically thick warm cloud (Cu/Sc type), optically thin cold cloud (thin Ci type/dense Ci), and N-type which is low level thin clouds. Based on all of the data from January and March 2014, cloud distribution on the field of study was dominated by Ci type clouds (thin Ci, thick Ci, and dense Ci). Dry characteristics of the area of Riau province influenced cloud development over the area and was dominated with fair weather. From the comparison between rain events and the cloud type, rain cloud determination cannot be done with only data point of TRMM rainfall data and MTSAT TBB data because it didn’t represent the relationship between rain events and it’s cloud type. Rain which fall on point study might not come from the clouds right on it due to the wind factor.

Menipisnya persediaan minyak bumi sebagai salah satu sumber energi telah membuat pemerintah Indonesia melakukan efisiensi energi dimana salah satunya adalah menjadikan bahan bakar gas sebagai bahan bakar alternative. Penelitian bahan bakar gas untuk kendaraanÂ telah dilakukan diberbagai negara termasuk Indonesia. Pada paper ini telah dilakukan kajian teknis mengenai pengaruh pemakaian berbagai bahan bakar gasoline yang tersedia dipasar Indonesia dan bahan bakar gas CNG pada kendaraan sedan dan MPV. Kajian ini bertujuan untuk mengetahui pengaruh penggunaan bahan bakar minyak khususnya bensin dan gas CNG pada emisi gas buang, konsumsi bahan bakar, dan biaya operasional kendaraan dengan menggunakan bahan bakar bensin dan CNG. Pengujian dilakukan dengan menggunakan 2 jenis kendaraan yaitu sedan dan MPV yang memiliki kapasitas silinder 1500 cc memakai 4 bahan bakar jenis bensin dengan nilai oktan yang berbeda-beda dan 1 bahan bakar gas (CNG). Metode uji emisi gas buang menggunakan standar Euro 2 sedangkan pengujian konsumsi bahan bakar menggunakan standar UN ECE R101. Hasil pengujian menunjukkan bahwa emisi gas buang untuk CO dan CO2 bahan bakar gas lebih rendah dari pada untuk bahan bakar bensin, tapi hal ini sebaliknya untuk emisi NOx dan THC.Â Tetapi untuk konsumsi bahan bakar gas yang disetarakan dengan LSP (liter setara premium) hasilnya lebih boros dibandingkan dengan bahan bakar bensin untuk satuan liter per km. Tetapi untuk biaya pemakaian bahan bakar per km, penggunaan bahan bakar gas CNG mempunyai nilai ekonomis yang lebih baik dibanding bahan bakar bensin dikarenakan harga bahan bakar gas CNG yang masih lebih rendah dibanding jenis bensin.

Published: December 2018

Pada makalah ini disajikan analisis lendutan balok beton dari sebuah gedung. Analisa dilakukan menggunakan software berbasis finite element method (FEM) dan eksperimental dengan tujuan untuk mengetahui pengaruh jenis tumpuan dan tipe penampang balok terhadap lendutan.
Dalam analisis menggunakan software FEM dilakukan perhitungan lendutan menggunakan persamaan lendutan balok pada dua tumpuan dengan asumsi sebagai penampang balok biasa dan penampang balok T. Selain itu, juga diperhitungkan kondisi tumpuan yaitu sebagai tumpuan sederhana dan tumpuan jepit-jepit. Dalam evaluasi secara eksperimental dilakukan uji beban terhadap balok beton yang bersangkutan sesuai SNI 2847 2013. Sebagai beban uji adalah air dan sebagai pengukur lendutan adalah linear variable displacement transducer (LVDT).
Perhitungan lendutan di tengah bentang dengan software berbasis FEM dengan asumsi balok T dan tumpuan jepit-jepit menghasilkan lendutan untuk balok C 1-2 sebesar 1,652 mm dan untuk balok 2 A-B sebesar 1,987 mm. Lendutan netto di tengah bentang hasil uji beban untuk balok C 1-2 adalah sebesar 1,263 mm dan untuk balok 2 A-B adalah sebesar 1,625 mm. Dengan demikian pada eksperimen ini dapat disimpulkan bahwa lendutan balok beton hasil evaluasi menggunakan software FEM melalui perhitungan dengan asumsi penampang balok T dengan kondisi tumpuan jepit-jepit adalah yang paling mendekati lendutan hasil evaluasi secara eksperimental melalui uji beban

Published: December 2018

There are different pollution sources, which affect soil including transportation, especially in highways. These effects can be assessed by Environmental Impact Assessment. In this study, seven sampling stations were selected in different distances (0, 10, 20, 50, 100 meter) along Tehran- Karaj highway. Samples were collected and their concentrations of Pb were measured using a FAAS after dry acid digestion. It was observed that the highway had a negative impact on the peripheral soil. These impacts were higher in Tehran with average lead concentrations, and declined by moving toward Karaj. Moreover, the average concentration of lead in soil significantly decreased by increasing distance from the roadside.
Highest lead concentration was in station (E) in the middle of the road with an average of 160.50 mg/kg. The highest average concentrations were observed in soils of the roadside with an average of 115.25 mg/kg. The highest concentration was also observed in station (B) and in the roadside, with a concentration of 302 mg/kg, which was above the international allowable limits. Tehran- Karaj highway is in the list of the most polluted roads in the world and it must be concerned for its lead pollution, especially in the roadside. Essential steps for controlling the negative impacts must be taken including the expansion of green-space along the highway.

Published: December 2018

Wireless sensor networks (WSNs) play an important role in many real-world applications like surveillance. Wireless networks are also used to have data transfer. In such cases, there are problems with resourcece-constraintnednetworks. The problems include a delay in communication and reduction in Quality of Service (QoS). Topology control can solve this problem to some extent. However, the delay performance and QoS need to be improved further to support intended operations in wireless networks. When relay node concept is considered, it is possible to optimize performance in such networks. In this paper, we proposed a Genetic Algorithm (GA) based relay configuration for optimizing delay performance in WSN. Relay nodes compute optimal positions using the proposed algorithm so as to improve QoS and reduce delay as much as possible. We implemented the algorithm using NS2 simulations. The results revealed that the proposed approach is able to improve QoS, reduce delay besides improving network performance in terms of throughput, network capacity, and energy efficiency.

Published: December 2018

Commercially pure titanium (cpTi) and titanium alloys are metallic implant materials usually used in dentistry and orthopaedics. In order to improve implant properties, Ti-based materials may be surface modified by different procedures. One of the most attractive methods is electrochemical anodization, as a method for obtaining nanotubular oxide layer on the material surface, aiming at improving mechanical, biological and corrosion properties of the metallic biomaterials. In the present study, ultrafine-grained titanium (UFG cpTi) was obtained by high pressure torsion (HPT) under a pressure of 4.1 GPa with a rotational speed of 0.2 rpm, up to 5 rotations at room temperature. In order to form homogeneous nanotubular oxide layer on the UFG cpTi, the electrochemical anodization was performed in phosphoric acid containing 0.5 wt. % of NaF electrolyte during anodizing times of 30, 60 and 90 minutes. The characterisation of thus formed nanotubes was performed using the scanning electron microscopy (SEM), while the surface topography was analysed using the atomic force microscopy (AFM). The results show that the electrochemical anodization process leads to an enhanced roughness of the surface. The mechanical behaviour of the UFG cpTi after the electrochemical anodization process is estimated using the nanoindentation technique. Obtained results show that anodized material has lower value of nanohardness than non-anodized material. Moreover, anodized UFG cpTi has lower modulus of elasticity than non-anodized UFG cpTi and the value is close to those observed in bones.

The aim of this study was to investigate the possibility of modifying model BisGMA/TEGDMA dental composite by substituting 10 wt. % of conventional glass fillers with bioactive fillers based on calcinated nanosized hydroxyapatite (HAp) and Mg doped hydroxyapatite (Mg-HAp). HAp and Mg-HAp powders were synthesized hydrothermally. Mechanical properties: hardness by Vickers (HV) and flexural strength (Fs) were tested initially and after being stored for 28 days in simulated body fluid (SBF). The experimental composites with HAp and Mg-HAp particles showed no statistically significant difference in HV compared to the control (p>0.05) either initially or after storage. Although mean Fs values of modified composites tested initially were lower (62 MPa) than those of the control (72 MPa), after 28 days of storage in SBF Fs values were greater for modified composites (42 MPa control sample, 48 MPa HAp and Mg-HAp samples). In vitro bioactivity of BisGMA/TEGDMA composites with HAp and Mg-HAp particles after 28 days in SBF was not detected.

On the Concept of Transportation Engineering Investigations
Authors: Il’in N. N. 
Published: December 2018

The paper addresses the current need to develop a special theory of the category of transportation engineering investigations, which remains underexplored to date. The author argues that the significance of these questions goes beyond the theoretical issues of their concept and classification, or definition of the subject, objects and objectives of investigation, and involves such practical aspects as the lack of adequate methodological resources to support most subcategories of examinations. The concept of transportation engineering investigations is articulated based on the general concepts of engineering and technology capturing the substance of this category of forensic examinations.
Developing the Language of the General Theory of Forensic Science
Authors: Krestovnikov O. A. 
Published: December 2018

We know from experience that the language of the general theory of forensic science, like any science, is an extremely complex and diverse phenomenon. This language is characterized by specific “constructs” that arise as a result of specialized activity and can be effectively applied not only in the context of the conceptual theoretical framework of forensic science, but also by enforcement professionals in their daily practice. In order to ensure clarity, accuracy and accessibility of expressions in the language of the general theory of forensic science, to avoid polysemy of terms, vagueness and ambiguity of their content, and equivocality of expressions, special attention should be paid to the logical semantic processes in terminology inherent in this language. At the same time, questions need to be raised and addressed about the development of a general concept of terminological activity and the need to regulate and standardize both domestic and international terminology used in forensic expert practice.

Basic methodological provisions are discussed, along with the possibilities of each forensic discipline when applied to the examination of these types of evidence, and required expert qualifications.
Investigation of Gaming Equipment Used in Illegal Gambling Operations
Authors: Sebyakin A. G. 
Published: December 2018

The article deals with certain aspects of investigating criminal cases related to illegal organization and operation of games of chance. The focus is on the application of various procedural forms of using specialized knowledge in computer technology, as well as the limits of an expert’s competence in this field. The author describes the main stages in the evolution of gambling equipment as a means of committing a crime, and compares the possibilities of equipment inspection by a specialist vs. a computer forensics examination. The application of these procedural forms is analyzed in the context of the origins of the gambling industry, which makes it possible to evaluate the performance of a procedural action (inspection of evidence) depending on the type of gaming equipment used. The advantages and disadvantages of both procedural forms of using specialized knowledge are described. The author addresses the persisting issue of the boundaries of expert competence when deciding whether the evidence under investigation qualifies as gaming equipment.

Authors: Jiménez Miguel , Pérez Cristina , Vega Carlos 
Published: December 2018

Introducción: Se presenta el reporte de un caso clínico de Lumbociatica Aguda cuya etiología se correspondió con un Absceso en el músculo psoas iliaco izquierdo, evidenciado como la presencia de una colección de pus en el compartimiento del músculo iliopsoas, entidad relativamente poco frecuente y con una presentación clínica inespecífica y larvada. El caso fue asistido en el Hospital Provincial General Latacunga en el año 2016. Las etiologías más frecuentes de la lumbociatalgia son las discopatías y hernias de disco, siendo el absceso del psoas una entidad poco frecuente, pero al ser los procesos infecciosos una causal de lumbalgia y lumbociatica, en el orden diagnóstico siempre debe ser considerada esta posibilidad.
Objetivo: Describir un caso clínico de Absceso del músculo Psoas Iliaco como causa de lumbociatalgia.
Material y métodos: Estudio descriptivo retrospectivo, presentación de caso clínico.
Resultados: Se reporta un caso atendido en el Hospital Provincial General de Latacunga, se trata de un paciente de 31 años con antecedentes de Pielonefritis aguda a los 19 años que acude por lumbociatalgia y se comprueba la presencia de un absceso del músculo psoas ilíaco como etiología del síntoma. El diagnóstico se realizó mediante exámenes de laboratorio, resonancia magnética nuclear de columna lumbar y ecografía abdominal. La conducta terapéutica se basó en antibioticoterapia de amplio espectro y la realización de un procedimiento mínimamente invasivo: drenaje del absceso por vía percutánea mediante la técnica de Seldinger guiado por ultrasonido. Los resultados fueron muy satisfactorios, con un seguimiento posterior durante un año.
Conclusiones: Se debe considerar el diagnóstico etiológico infeccioso ante una lumbociatalgia aguda, y entre sus variedades, tener en cuenta el absceso del músculo psoas ilíaco, aunque las discopatías y hernias del disco, le superen en frecuencia.
