Published: September 2021

Salah satu energi alternatif pengganti bahan bakar fosil yang berkembang di masyarakat Indonesia adalah Bahan Bakar Gas (BBG) diantaranya Liquified Petroleum Gas (LPG). Akan tetapi konversi BBM ke BBG di Indonesia saat ini belum terlihat secara nyata kemajuan perkembangannya. Kendala selain tingginya harga satu paket konverter kit di pasaran adalah performa yang di hasilkan oleh LPG masih relatif kecil dari Pertamax. Oleh karena itu penulis mencoba membuatkan Konverter Kit baru dengan harga yang lebih terjangkau dan performa yang di hasilkan lebih baik dari Pertamax. Untuk mengetahui performa mesin dari pemakaian Konverter Kit LPG buatan ini maka perlu dilakukan pengujian terhadap daya dan konsumsi bahan bakar spesifik dari penggunaan LPG dan dibandingkan dengan Pertamax. Masing-masing pengujian dilakukan dengan perpindahan persneling dan putaran mesin yang sama antara 2000 hingga 6000 rpm. Dari hasil pengujian penggunaan bahan bakar LPG menghasilkan Daya sebesar 32,87 Hp sedangkan Pertamax sebesar 24,61 Hp dan Konsumsi Bahan Bakar yang lebih baik dibandingkan bahan bakar Pertamax dimana SFC LPG sebesar 17,79 gr/Hp.dt dan Pertamax sebesar 12,11 gr/Hp.dt. LPG dari Konverter Kit buatan ini lebih hemat bahan bakar, dan menghasilkan daya yang lebih besar dibandingkan Pertamax, sehingga menghasilkan SFC yang lebih baik dibandingkan Pertamax.
One of alternative energy substitute for fossil fuels that is developing in Indonesian society is Gas Fuel (BBG) including Liquified Petroleum Gas (LPG). However, the conversion of BBM to BBG in Indonesia is not yet visible in the progress of its development. The obstacle besides the high price of one converter kit package on the market is the performance produced by LPG is still relatively small than Pertamax. Therefore, the author tries to make a new converter kit with a more affordable price and better performance than Pertamax. To find out the engine performance of the use of this artificial LPG Converter Kit it is necessary to test the specific power and fuel consumption of LPG usage and compare with Pertamax. Each test is carried out with the same gear shift and engine speed between 2000 and 6000 rpm. From the results of testing the use of LPG fuels produce power about 32,87 Hp and Pertamax produce power about 24,61 Hp and fuel consumption more good compared to Pertamax fuels, which is 17,79 gr/Hp.s for LPG and 12,11 gr/Hp.s for Pertamax. The LPG from this artificial converter kit is more fuel efficient, and produces more power than Pertamax, so it produces a better SFC than Pertamax.

Mesin pencoak pipa (pipe notcher) yang ada di pasaran saat ini harganya cukup mahal sehingga banyak bengkel-bengkel kecil masih menggunakan cara konvensional untuk melakukan pencoakan pipa. Cara yang biasa digunakan adalah dengan menggunakan gerinda tangan, sehingga membutuhkan waktu yang lama dan hasilnya kurang presisi. Untuk itu pada penelitian ini dirancang mesin pencoak pipa dengan memanfaatkan sabuk amplas sebagai V-belt yang dihubungkan dengan poros dan digerakkan oleh motor listrik. Kemudian benda kerja didekatkan pada poros matras dan selanjutnya ditekan maju sampai terbentuk profil yang diinginkan. Rancang bangun mesin pencoak pipa multi dimensi ini terbagi dalam tiga tahap. Tahap pertama konsep desain dan perencanaan komponen, dilanjutkan dengan tahap pembuatan dan terakhir adalah pengujian mesin. Dari hasil rancang bangun diperoleh bahwa mesin pencoak pipa multi dimensi ini menggunakan motor listrik 0,5 HP dan putaran 1400 rpm sedangkan rangka mesin menggunakan besi siku ukuran 4 x 4 cm. Setelah dilakukan pengujian, mesin dapat bekerja dengan baik. Untuk mencoak pipa dengan diameter 3/4 inch dibutuhkan waktu selama 0,335 menit, sedangkan untuk pipa ukuran 1 inch membutuhkan waktu selama 1,075 menit. Sedangkan profil yang dibuat menggunakan mesin ini mampu membentuk sudut antara 0° sampai dengan 30°.
Pipe notcher on the market today are quite expensive so that many small workshops still use the conventional method for cutting special pipe profiles. The method commonly used is to use hand grinding, so it takes a long time and the results are less precise. For this reason, in this study was designed a pipe notcher machine using the sandpaper belt as a V-belt connected to a shaft and driven by an electric motor. Then the workpiece is brought closer to the mattress axis and then pressed forward until the desired profile is formed. The design of this multidimensional pipe notcher engine is divided into three stages. The first stage is the design concept and component planning, followed by the manufacturing stage and the last stage is machine testing. From the design results, it is found that this multi-dimensional pipe notcher machine uses an electric motor 0.5 HP and a rotation of 1400 rpm while the engine frame uses 4 x 4 cm angle iron. After testing the machine can work properly. To check a 3/4 inch pipe it takes 0.335 minutes, while for a 1 inch pipe it takes 1.075 minutes. Meanwhile, the profiles made using this machine are capable of forming angles between 0 ° to 30 °.

Keep the thread up! From humour to poetry. Silence as a spur to read and speak
Authors: Perrot Jean 
Published: September 2021

The purpose of this article is to proceed with a semiotic examination of several wordless picturebooks focussed on the use of a thread, Considering that it is the visual image which first and foremost prompts the meaning in iconotexts, we shall deal with it more particularly through the examination of two French picturebooks: the first one by Robert Scouvart, Histoire d’un fil (The Story of a Thread, Magnard 1990) shows how a single thread can magically delineate different characters introduced in an alluring play on words. The book will offer a distanced staging of the reading process through a humorous use of stereotypes close to those resorted to in comic strips. In the second part of my presentation we shall deal with Boutique Tic Tic, (Shop Pop Pop) by Frédéric Clément, (Albin Michel Jeunesse, 2018) a poetical description introduced under the aesthetic spell of Lewis Carrol’s The Adventures of Alice in Wonderland, as suggested by the image of the white rabbit winking from a globe on the cover page. The book in the end will tell how a magical thread can unexpectedly and poetically have a « golden voice » during « a long minute of silence of Big Ben »… An original achievement fully illustrating Sandra Becket’s declaration that « the ‘interactive’ and ‘cinematic’ qualities of similar productions [...] make them books for the ‘digital age.’ (2012, p. 99)

Published: September 2021

Dam overtopping failure and the resulting floods are hazardous events that highly impact the inundated areas and are less predictable. The simulation of the dam breach failure and the flood wave propagation is necessary for assessing flood hazards to provide precautions. In the present study, a two-dimensional HEC-RAS model was used to simulate the flood wave resulting from the hypothetical failure of Al-Udhaim Dam on Al-Udhaim River, Iraq, and the propagation of the resulting dam-break wave along 100 km downstream the dam site for the overtopping scenario. The main objective is to analyze the propagation of the flood wave so that the failure risk on dam downstream areas can be assessed and emergency plans may be provided. The methodology consisted of two sub-models: the first is the dam breach failure model for deriving the breach hydrograph, and the second is the hydrodynamic model for propagating the flood wave downstream of the dam. The breach hydrograph is used as an upstream boundary condition to derive the flood impact in the downstream reach of Al- Udhaim River. The flood inundation maps were visualized in RAS-Mapper in terms of water surface elevation, water depth, flow velocity, and flood arrival time. The maximum recorded values were: 105 m (a.m.s.l.), 18 m, 5.5 m/s, and, respectively. The flow velocity decreased from upstream to downstream of the terrain, which means less risk of erosion in the far reaches downstream of the study area. The inundation maps indicated that the water depth and flow velocity were categorized as Catastrophic limits on the terrain's area. The results offer a way to predict flood extent and showed that the impact of a potential dam break at Al-Udhiam Dam will be serious, therefore, suitable management is needed to overcome this risk. Moreover, the maps produced by this study are useful for developing plans for sustainable flood management. Doi: 10.28991/cej-2021-03091739 Full Text: PDF
La contemplación según Plotino
Authors: Ibérico Rodríguez Mariano 
Published: September 2021

Cuando se leen en las Enéadas las páginas dedicadas de modo expreso y directo al estudio de la contemplación, es imposible evitar una primera impresión de desconcierto. Porque se diría que, según Plotino, todo es contemplación: la naturaleza, el alma, la razón, la inteligencia. Y así este concepto a causa de su gran extensión, parece que perdiera su especificidad. Mas esta impresión desaparece, y la meditación la reemplaza por un sentimiento más adecuado y más alto: la admiración ante la profundidad y los vastos alcances de la doctrina que es al propio tiempo una psicología, una estimativa y una ontología de la contemplación.

Increasing Service Life of a Railway Wheel with Surface Hardening Technology
Authors: Bunkova T. G. 
Published: September 2021

The article presents surface hardening technology as applied to solid-rolled wheels of rolling stock. The obtained results of the theoretical study on the process of strengthening the metal of the wheel will make it possible to develop scientifically grounded technological and technical solutions to prevent formation and development of defects on the rolling surface, as well as to eliminate them during maintenance.The objective of this work is to identify the optimal method for surface hardening of a railway wheel with defects.At present, the issue of extending service life of elements and critical parts of rolling stock is becoming increasingly acute. Due to the limited economic feasibility and limited availability of existing production technologies, it becomes necessary to create a new material modified with nanoclusters and hardened with surfactants.Nanoclusters have high plasticity and hardness values. To determine the hardness value of nanomaterials, the Vickers hardness test method is used, in which hardness is determined by the size of the area of the indentation after removing the load from the pyramid shaped diamond.Superplasticity is observed in nanostructures. For nickel and nickel-aluminium alloy NiAl3, low-temperature superplasticity is observed in the temperature range 450–470°C, which is three times lower than their melting point.

Survival Mechanism of The Shia Community Post-Shia–Sunni Sampang Conflict in 2012
Authors: Khoiri Muhammad Aziz , Chamankhah Leila 
Published: September 2021

The purpose of this article is to discuss the mechanisms that the Shia community of Rusunnawa Puspa Agro Sidoarjo adopted to survive the sectarian conflict of 2012. This research uses a qualitative approach, using a snowball sampling technique with key informants, Ustad Tajul Muluk and Ustad Iklil. Data collection techniques include in-depth interviews. The result is indicative of the fact that the Shia community took three approaches to survive the sectarian clashes. First, the Shia community attempted to reduce its daily expenses to the most urgent needs. Second, the Shia community members used an alternative subsystem of working as coconut shelling labor, farming the surrounding land, and raising goats and chickens to help meet their daily needs. Third, the Shia community members got a governmental network in the form of jadup money,[1] in the form of the patron-client relationship. This research also shows that the Shia community needs to get social support because material assistance is not enough

[1] - Jadup is the acronym of jatah hidup, and Jatah is a financial help which is either provided by the government, or parents, or even one’s boss, but not because one has done something, but rather, because it is part of one’s right.
