Authors: Awan Rabia , Fatima Ghulam , Jahanzaib Muhammad 
Published: February 2022

Purpose: Cognitive mapping of spaces is vital to the progress of well-organized orientation and mobility skills. Mostly the information required for cognitive mapping is acquired through the sense of vision. Persons with visual impairment lack in this critical information, and in consequence, they face difficulties in mapping as well as navigating new spaces. This study was aimed to investigate the cognitive mapping abilities of persons with visual impairment for the purpose of improvement in their independent movement.
Design/Methodology/Approach: The population of this quantitative study comprised persons with visual impairment residing in district Lahore, Pakistan. The convenient sampling technique was used for taking the sample of 30 persons having visual impairment. A self-developed questionnaire (Cronbach Alpha: 0.78) consisting of 36 items on five-point Likert scale (strongly agree to strongly disagree) was used to gather data through online mode. Descriptive and inferential statistics were used to analyze data.
Findings: The findings of the study revealed that the persons with visual impairment used language audition and haptics to get a direct or indirect awareness of their physical environment. The usage of assistive devices play an important role in their lives.
Implications/Originality/Value: The study suggested the strong need to assess the cognitive mapping abilities of persons with visual impairment through an increased sample and experimentation to improve their quality of life by increasing mobility and independence.

Published: February 2022

ABSTRAKKarakteristik blade sisi cekung turbin hidrokinetik Savonius yang memiliki nilai torsi negatif mengakibatkan kelemahan berupa efisiensi turbin yang relatif rendah, sehingga diperlukan sistem pengarah aliran berupa rectifier guide vane. Studi ini bertujuan membandingkan performa yang dihasilkan turbin Savonius tanpa guide vanes dan turbin Savonius menggunakan guide vanes dengan memvariasikan lebar rectifier L=Rt/4, L=Rt/2 dan L=3Rt/4, dimana Rt adalah jari-jari turbin. Metode pengujian dilakukan secara eksperimental di saluran prismatik dengan kecepatan aliran 0,111–0,1415 m/s. Hasil studi menunjukkan bahwa penambahan guide vanes dengan variasi lebar rectifier L=Rt/4, L=Rt/2 dan L=3Rt/4 masing-masing menghasilkan peningkatan torsi sebesar 29,9%; 33,3%; dan 36,3%. Turbin Savonius menggunakan guide vanes dengan lebar rectifier L=3Rt/4 menghasilkan coefficient of torque (Ct) dan coefficient of power (Cp) yang lebih tinggi dibandingkan variasi lebar rectifier (L) lainnya, sehingga kinerja turbin meningkat.Kata kunci: coefficient of power, hidrokinetik, savonius, rectifier guide vanes ABSTRACTThe characteristic of the concave side blade of the Savonius hydrokinetic turbine which has a negative torque value, it leads to the weakness in the form of a relatively low turbine efficiency, thus a flow steering system is needed in the form of a rectifier guide vane. The aim of this study was to compare the performance of the Savonius turbine without guide vanes and the Savonius turbine using guide vanes by varying the width of the rectifier L=Rt/4, L=Rt/2 dan L=3Rt/4, where Rt is the turbine radius. The test method was undertaken experimentally in a prismatic channel with a flow velocity of 0.111–0.1415 m/s. The results of the study pointed out that the addition of guide vanes with variations in the width of the rectifier was L=Rt/4, L=Rt/2 dan L=3Rt/4 and each of them had an increase in torque of 29.9%, 33.3% and 36.3%. The Savonius turbine used guide vanes with a rectifier width of L=3Rt/4 and it resulted a higher coefficient of torque (Ct) and coefficient of power (Cp) compared to other variations of rectifier width (L), thus, the performance of turbine increased.Keywords: coefficient of power, hydrokinetic, savonius, rectifier guide vanes
Kajian Kepekaan Aspal terhadap Temperatur pada Aspal dengan Pemanfaatan Subtitusi Getah Karet Alam
Authors: Widianto Barkah Wahyu , Faisal Mochammad Isa 
Published: February 2022

ABSTRAKAspal merupakan material pengikat perkerasan lentur yang sangat peka terhadap temperatur. Salah satu cara mengurangi sifat kepekaan tersebut adalah melakukan modifikasi aspal dengan subtitusi getah karet alam sebagai pemanfaatan sumber daya alam. Hal ini didukung dengan peningkatan penghasilan rata-rata karet alam di Indonesia tahun 2015-2020 adalah 1,5%; dimana penghasilan karet terbesar 28,77% di Provinsi Sumsel. Penelitian ini bermaksud menganalisis tingkat kepekaan aspal terhadap temperatur dengan nilai indeks penetrasi (IP) aspal dengan nilai penetrasi 60/70 disubtitusi pada persentase tanpa getah dari karet alam; subsitusi 2,5%; subsitusi 5%; dan subsitusi 7,5%. Hasil penelitian menghasilkan bahwa nilai IP semakin meningkat dengan ditambahnya Persentase karet alam; yaitu -0,347 untuk 0%; -0,179 untuk 2,5%; 0,419 untuk 5%;, dan 0,557 untuk 7,5%. Hal ini menunjukkan bahwa dengan bertambahnya persentase karet sehingga aspal bertambah keras dan kurang peka terhadap temperatur karena kandungan getah karet alam yang non bitumen. Hal ini dapat diindikasi bahwa dengan bertambahnya Persentase karet maka aspal semakin tahan terhadap deformasi tetapi rentan terhadap retak.Kata kunci: indeks penetrasi, getah karet alam, aspal ABSTRACTAsphalt is a flexible pavement binder which is very sensitive to temperature. One way to reduce this sensitivity is to modify asphalt by substituting natural rubber latex for the use of natural resources. This is supported by an increase in natural rubber production in Indonesia by an average of 1.5% in 2015-2020, where the largest rubber production is 28.77% in South Sumatra Province. This study aims to assess the sensitivity level of bitumen to temperature with the penetration index (IP) value of 60/70 pen asphalt substituted with natural rubber latex levels of without subtitution, 2,5% subtitution, 5% subtitution, and 7,5% subtitution. The test results showed that the IP value increased with the addition of natural rubber content, namely -0.347 for 0%, -0.179 for 2.5%, 0.419 for 5%, and 0.557 for 7.5%. This shows that with increasing rubber content, the asphalt is getting harder and not sensitive to temperature because of the non-bituminous natural rubber latex. It can be indicated that asphalt is increasingly resistant to deformation but susceptible to cracking.Keywords: penetration index, natural rubber latex, asphalt

O Deus Vivo liberta e reúne o Povo dos Pobres
Authors: Anderson A. F. , Gorgulho G. 
Published: February 2022

No IV Encontro das CEBs, em Itaici, SP, ficou claro como a Palavra de Deus, a liturgia (ou a celebração popular) fazem parte integrante da vida das comunidades inseridas na prática da libertação dos pobres. Os biblistas presentes nesta reunião viram na tríplice integração da Palavra de Deus, da vida/luta, e da celebração, um comentário vivo do movimento deuteronomista no Antigo Testamento. Ele fez a teologia do Povo de Deus que se organiza pela convocação da Palavra de Deus, organiza-se a partir da prática de defesa do direito dos pobres, e a liturgia é a fonte permanente de vitalidade pela memória do ato da libertação.
Gostaríamos, então, de apresentar uma sugestão de leitura teológica do livro do Deuteronômio a fim de, com sua ajuda, compreender melhor a atual caminhada das comunidades que procuram compreender-se como o povo que se organiza para a libertação. O Deuteronômio torna-se tanto mais importante quando vemos que Jesus de Nazaré ao libertar o povo do antigo sistema da Lei e ao organizar a comunidade dos pobres inspirou-se profundamente no espírito deuteronomista da dádiva e da partilha (Mt 12,7s).

Penerima beasiswa merupakan siswa yang tergolong pada kondisi kurang mampu secara material. Dalam hal ini, SMA Muhammadiyah 08 Gresik membantu siswa yang berprestasi selama menempuh studinya berupa potongan biaya SPP (Sumbangan Pembinaan Pendidikan) per bulan. Proses seleksi penerima beasiswa pada SMA Muhammadiyah 08 Gresik dilakukan dengan beberapa tahap yaitu siswa yang mendaftar mengumpulkan raport dan diberi form untuk diisi yang kemudian akan dicatat oleh guru BK dan setelah itu dilakukan proses pengambilan keputusan berdasarkan nilai raport tertinggi. Pengambilan keputusan tersebut dirasa kurang efektif karena ada kemungkinan siswa mempunyai nilai raport yang sama sehingga mengakibatkan sulitnya membandingkan siswa yang layak menerima beasiswa. Oleh karena itu diperlukan sebuah sistem pendukung keputusan yang dapat menunjang dalam pengambilan keputusan penerima beasiswa sehingga guru dapat mengambil keputusan secara tepat dan akurat.Hasil dari implementasi sistem pendukung keputusan penerima beasiswa menggunakan metode ELECTRE II (Elimination Et Choix Traduisant la Realite) yang dibuat dapat membantu dalam proses pemilihan penerima beasiswa berdasarkan kriteria yang sudah ditentukan.
