With consideration, 1) if the body (lahiriyah) in hadas condition, it is not obligate his pray (I'adah), 2) if the PPE is unclean then it is necessary to repeat the prayer. The fatwa cannot be separated from the syar'i argument which is the basis for issuing the fatwa, particularly using the talfiq manhaji method. The fatwa can be used as an alternative to confusion over the law, and is intended to create benefits, especially for health workers who treat and handle Covid-19 patients.
The Application of the Principle of Judges’ Independence in Blasphemy Cases in Indonesia's Post-Reform Era
Authors: Maula Bani Syarif , Ariyanti Vivi
Published: November 2021

This research departs from a paradigm that the freedom of judges is a form of court independence, which requires that decisions taken must consider objectivity without pressure from any party. This study focuses on the attitude of judges' independence from factors that can influence court decisions, both internal and external factors related to the interests of certain groups. Based on these problems, this study addresses the issue of the independence of judges in cases of blasphemy. This type of research is empirical normative with a qualitative descriptive approach. The data sought for this research is data that comes from the facts of the application of material and formal law by judges in court. In addition, this data is also strengthened by interviews. This study concludes that the analysis of the application of the blasphemy article proves that judges as law enforcers have difficulty translating the substance of blasphemy because of the unclear formulation of Article 156a letter 'a' of the Indonesian Criminal Code. The judge's decision in the blasphemy case does not reflect the independence values of the judges who decide the case. Judges in making decisions on cases handled must be based on their ability to think and will freely (independently) but within the limitations of responsibility and objectivity. The panel of judges in blasphemy cases tends to adopt a more general and situation-oriented attitudes.

This research is an empirical research using a socio-legal approach. The data used is qualitative data which is analyzed descriptively qualitatively. The findings from this study are the basis and method of dividing inheritance of different religions in Nagari Preparation Bancah Kariang, Kinali District, West Pasaman Regency is based on the habits that have been carried out by the family so that it has been passed down from generation to generation until now and the distribution of inheritance is carried out equally, regardless of religion. in a family member after the death of an heir. This is done with the aim of maintaining harmony among his family and is considered a fair distribution of inheritance with a family system. Families that have family members of different religions also get an equal share and do not differentiate the income from inheritance to their children to strengthen the relationship between children and their parents. The practice carried out by the Nagari Bancah Kariang community clashes with the Prophet's hadith which clearly states that different religions are a barrier to inheriting under any pretext because ikhtilaf al-diin is one of the mawani '(barriers) in Islamic inheritance law.

Published: November 2021

Communication is an interactive process that expresses the transfer of feelings and thoughts to the person or persons addressed. The main purpose of communication is to ensure that communication progresses more effectively by minimizing barriers so that sharing between individuals and society can become more efficient. One of the points that hinder effective communication is communication conflicts. It is possible to examine communication conflicts in three groups as intrapersonal, interpersonal and social conflicts.
Communication skills are shaped by the examples that the individual receives from environment since infancy. For this reason, it can be said that family, school and other social environments affect communication skills. It seems possible for individuals to benefit from literary works as well as the mentioned social environments for effective communication. It can also be said that communication skills can be improved thanks to the messages and skills implicitly given in the works of high literary quality, which are brought together with the individual especially from childhood. Qualified children's literature works develop the individual holistically; provides various communication environments to the child by embodying them. It seems possible to come across examples of effective communication and communication barriers in these works.
In this study, which was prepared considering the relationship between communication skills and children's literature, it was aimed to determine the communication conflicts in the translated children's literature. For this purpose, the source tools of the study were determined by random sampling method; The descriptive analysis method was used in the study in which document analysis was carried out in accordance with the qualitative research approach.
“Küçük Cadı Yeşil” by Marie Desplechin, “Bunun Adı Findel” by Andrew Clements, “Hayvanlar Toplantısı” by Erich Kastner and “İçimdeki Büyükanne” by Maria Machado were examined as resource tools of the study. In the classification of communication conflicts, the work “İletişim Çatışmaları ve Empati” by Üstün Dökmen, who translated the work of Harary and Batell into Turkish, was used. The work is in the process of completion.

Published: November 2021

Learner autonomy is the ability to take charge of one's own learning, have the capacity for detachment, critical reflection, decision making, and independent action. There have been studies conducted on learner autonomy at university level but not at the secondary school level. This mixed type research was aimed to explore secondary school EFL teachers' perceptions about what learner autonomy is, what the teachers’ role in promoting learner autonomy, desirability and feasibility of learner autonomy is. The participants were selected by purposive sampling method. A questionnaire and a structured interview, which were designed by Al-Busaidi (2012) was adopted and implemented. The data collected from the questionnaire were analyzed with SPSS 26.0 software and the data collected through structured interviews was exposed to qualitative thematic analyses. The results reveal that one of the biggest challenges in implementing learner autonomy is students’ lack of motivation, interest, and reluctance to take responsibility of their learning. It is also confirmed that there is a strong correlation between the motivation and learner autonomy both of which trigger the development of each other.

The aim of this study is to determine the mathematical concepts in children's books. The examined books were selected by looking at the preference rates of the books in the library located in the city center according to their class levels. A set of ten books from the 2nd grade, 3rd grade and 4th grade levels were determined by the criterion sampling method. The book chosen for the 2nd grade is a series called Ünlülerle Bir Gün-1. The book chosen for the 4th grade is the series named Kurtuluşun Kahramanları. Because one series of the 3rd grade book set consists of five books, the second and fourth series were examined. The books chosen for the 3rd grade are Türkiye’yi Geziyorum 2 and Türkiye’yi Geziyorum 4 which are belong to Levent series. Since no data could be obtained about the most preferred books at the 1st grade level, 10 books with 5 or more editions were selected and a total of 40 books were examined. The books chosen for the first grade consist of the books in the sets named Çağlar'ın Maceraları, Elif’in Maceraları and İnci'nin Maceraları. Descriptive analysis was used to examine the collected data. Themes were first created within the framework of 3 basic learning areas in the Ministry of National Education's Mathematics Teaching Program.

Steam drying process of the Low Rank Coals (LRCs) has been conducted to produce coal which is comparable with the High Rank Coal (HRC). Characterization of the raw and dried coals was carried out through proximate, ultimate, calorific value, Fourier Transform Infrared (FTIR) spectroscopy and Thermo Gravimetry-Differential Thermal Analysis (TG-DTA) to study the combustion behavior of the coals. This study used Indonesian low rank coals coming from Tabang (TKK coal) and Samurangau (SP coal), East Kalimantan. The results indicate that the calorific value of the dried coals increases significantly due to the decrease in moisture content of the coal. The FTIR spectrums show that the methylene-ethylene (RCH3/CH2) and aromaticity-aliphaticity ratios (Rar/al) of the dried coals increased while the ratio of RCO/ar decreased which reflect that the rank of the coals increased equivalent to the high rank coal (bituminous). Meanwhile, the TG-DTA indicates that the ignition temperature (Tig) and combustion rate (Rmax) of the dried coals increased. This analysis expresses that the dried coals produced by steam drying process have better combustion behavior due to the higher calorific value than those of the raw coals.

The Cuckoo Search (CS) is a very fast and efficient global optimization method to locating the slip surface which carried out by iteration. However, the Grid Search (conventional method) method in 3D slope stability analysis takes longer than this method on the computation process. Slope stability analysis was performed using the 3D limit equilibrium method “Bishop” with Cuckoo Search of slip surface by maximizing iteration of the simulation and columns in X or Y. To ensure that the slip surface within the global minimum slip surface, the maximum iteration in CS was also specified from 40 to 1200. Based on maximum columns in X or Y, the safety factor value of the 3D CS results was then compared to the Grid Search results to determine the final 3D safety factor and the estimated volume of potential failure. The final 3D safety factor obtained from the average 3D safety factor (with maximum iteration 400, 800, 1000, and 1200) is about 2,01 with the average estimated volume of slope failure of 190.000 m3 that located at the north of the pit.

One of the important issues to study underground coal gasification (UCG) is the prediction of surface subsidence. Several parameters that influence these conditions are the thickness of cap rock, the physical and mechanical characteristics, the structure condition, the minerals composition of the rock, and external conditions. This study had been carried out simulation and modeling to determine the level of surface subsidence risk and the effect of high temperatures due to the activities. The modeling results show that the thickness of the rock above the UCG coal seam greatly affects the surface subsidence. The depth is more than 200 m and found that the SF value is 1.59 which indicates UCG reactor depth of ≥ 200 m is safe from the risk of subsidence. From the characteristic aspect of the cap rock, the claystone types which not contain kaolinite minerals are more prone to collapse than those of contain kaolinite minerals. From this models, the gasifier at 150 m depth was estimated that there will be a decline of -7.23 m, and the minimum subsidence is at 275 m about 0.1 m. The heat propagation modeling results show that at 50 m the temperature is estimated to be 213- 289°C, but if the thickness of the cap rock is > 200 m depth, the temperature is around 29-28°C.

Based on the 2018, there a mining plan, two temporary sumps, namely the ABC and BCD sumps. They located in a mining sequence pattern. These sumps required a mud loading process prior to mining the coal below the sequence. The mud loading process is loaded sequentialy. However, the problem occurs when the mud loading process in the ABC sump is delayed, and resulted only 42% of mud production. Such the delay resulted in hindering the mining sequence pattern which forced changes in plans, designs, and decrease of coal production. These condition led to study the cause, impact, and alternative solution of the delay during mud loading process. The method used in this study includes direct observations and data collection of working conditions, equipment capabilities, material properties, and operation timeline. In this study, the statistical analysis is used to determine the cause and effect of delayed mud loading process. A Minex Software is then used to simulate the alternative of redesign the mining sequence pattern. The study found that the delay in mud loading process is due to the external and internal factors, that result in underproduction of coal only 505,833 tons, and delayed of coal production around 64 days. An alternative that can be conducted is to change the direction progress to the area that has low stripping ratio. Factors that can hinder the progress are need to be considered for anticipating the plan distraction at mid-term-plan.

Published: November 2021

Penelitian ini dilakukan untuk mengetahui karakteristik Lapisan Batubara E dan pengaruh struktur geologi/intrusi batuan beku terhadap parameter kualitas lapisan batubara tersebut di Sub-cekungan Palembang Selatan. Informasi mengenai karakteristik kualitas lapisan batubara ini masih sangat minim, karena berada jauh di bawah permukaan bumi, sehingga menyulitkan untuk diteliti secara komprehensif. Hal tersebut berbeda dengan Lapisan Batubara A1, A2, B1, B2, dan C yang sudah banyak diteliti oleh peneliti terdahulu, karena lapisan tersebut tersingkap di permukaan, sehingga mudah untuk diteliti. Penelitian ini bertujuan untuk mengorelasikan kualitas Lapisan Batubara E dengan struktur geologi. Struktur tersebut berupa sesar normal yang dilalui oleh intrusi batuan andesit berarah timurlaut/baratdaya yang mengontrol daerah penelitian. Pengamatan dilakukan terhadap percontoh batubara hasil pengeboran eksplorasi pada lubang penambangan Air Laya. Analisis yang dilakukan meliputi parameter kualitas berupa tingkat kematangan (reflektansi vitrinit) dan nilai kalor yang merupakan indikator ada tidaknya pengaruh struktur geologi (intrusi andesit) terhadap lapisan batubara tersebut. Hasil penelitian menunjukkan bahwa kualitas lapisan batubara tersebut terpengaruh oleh struktur geologi/intrusi andesit yang diinterpretasikan dari data anomali nilai reflektansi vitrinit dan nilai kalor pada masing-masing percontoh. Hasil analisis pada percontoh BAL 03 diperoleh nilai Rvmax = 0,63% dan nilai kalor = 8.345 kkal/kg dengan kategori batubara sub-bituminus; pada percontoh BAL 07 didapatkan nilai Rvmax = 0,78% dan nilai kalor = 8.315 kkal/kg dengan kategori batubara bituminus yang mengandung zat terbang tinggi, sedangkan pada percontoh lubang bor BAL 02 didapat nilai Rvmax = 0,45% dan nilai kalor = 6.836 kkal/kg, percontoh BAL 04 didapatkan nilai Rvmax = 0,43% dan nilai kalor = 6.775 kkal/kg, percontoh BAL 05 didapatkan nilai Rvmax = 0,46% dan nilai kalor = 7.115 kkal/kg, percontoh BAL 06 didapatkan nilai Rvmax = 0,47% dan nilai kalor = 6.950 kkal/kg. Semuanya masuk dalam kategori batubara sub-bituminus. Dapat disimpulkan bahwa percontoh di lokasi BAL 03 dan BAL 07 terpengaruh oleh struktur geologi (intrusi andesit), sedangkan percontoh di lokasi BAL 02, BAL 04, BAL 05, dan BAL 06 tidak terpengaruh. Interpretasi tersebut didukung dengan terdapatnya tiga rentang nilai reflektansi vitrinit (Rvmax) pada Lapisan Batubara E, yaitu 0,4 - 0,5%, 0,58 - 0,66 dan 0,74 - 0,82%.

Gasifikasi batubara bawah tanah adalah proses gasifikasi batubara secara in-situ pada lapisan batubara yang jauh di bawah tanah dengan cara melakukan injeksi udara bertekanan melalui sumur bor dan menghasilkan gas bakar batubara melalui sumur produksi. Salah satu permasalahan yang perlu diperhatikan dalam proses gasifikasi ini adalah kerusakan konstruksi sumur bor pada saat menginjeksikan udara bertekanan ke dalam sumur, ketika akan membuat jalur koneksi antara sumur injeksi dan produksi. Beberapa faktor yang perlu dievaluasi adalah tegangan dan regangan maksimum, distribusi tegangan dan regangan dan distribusi temperatur di sekitar lokasi sumur tersebut. Analisis dan pemodelan geomekanika dilakukan terhadap kondisi di sekitar sumur bor injeksi dengan memerhatikan kekuatan dan ketebalan casing, karakteristik batuan, kekuatan dan daya lekat penyemenan yang merupakan pengontrol rusak atau tidaknya sumur bor tersebut. Dengan asumsi nilai faktor keamanan ≥1,3, tegangan horizontal maksimum yang aman adalah 30 MPa dengan perolehan nilai tegangan maksimum di sekitar lubang bor sebesar 454,07 MPa, tegangan minimum 0,476 MPa dan regangan maksimum sebesar 0,08 m, serta distribusi temperatur berkisar antara 272,84-22°C dengan nilai terbesar di tengah lubang bor. Dengan demikian udara bertekanan maksimum yang diizinkan melalui konstruksi sumur injeksi adalah sebesar 30 MPa.

Kestabilan lereng adalah faktor penting pada pekerjaan penambangan kuari karena berkaitan dengan keamanan dan keselamatan pekerja dan peralatan. Kestabilan lereng dipengaruhi oleh beberapa faktor di antaranya dimensi lereng, sifat fisik dan mekanik batuan, struktur geologi batuan serta faktor gaya luar yang bekerja pada lereng tersebut. Pada studi ini, kestabilan lereng diprediksi menggunakan analisis kinematika berdasarkan jenis gerakan material lereng, tanpa menganalisis gaya-gaya penyebab material lereng tersebut bergerak, sehingga yang diamati adalah fenomena struktur batuan berupa arah utama bidang diskontinuitas. Tujuannya adalah memprediksi kemungkinan arah dan terjadinya longsoran lereng. Faktor yang diperhitungkan hanya arah bidang diskontinuitas terhadap arah bidang lereng, sudut kemiringan bidang diskontinuitas dan sudut kemiringan bidang lereng. Hasil analisis menunjukkan beberapa lereng berpotensi longsor dengan tipe planar (plane failure) dan baji (wedge failure). Dari 10 lokasi pengukuran yang ditentukan secara acak, diketahui ada 4 lokasi berpotensi longsor planar 4 dan 5 lokasi longsor baji. Dalam hubungannya dengan arah dan kemiringan lereng, potensi tersebut terjadi di 4 lokasi pengukuran, sedangkan di lokasi lainnya diperkirakan aman karena tidak searah dengan bidang lereng. Kekar dan rekahan tidak menunjukkan arah dominan tertentu tetapi terdapat tendensi pada kwadran 2 dan 4.

Pasir besi titan Yogyakarta mengandung berbagai jenis mineral baik berupa mineral bijih (mengandung Fe dan Ti) maupun mineral non-bijih (tidak mengandung Fe dan Ti). Mineral-mineral tersebut dapat diidentifikasi menggunakan difraksi sinar-x (XRD). Namun, karakterisasi XRD memiliki kesulitan tersendiri dalam analisis mineral karena selalu muncul ambiguitas fasa mineral dalam satu puncak difraksi yang sama. Hal ini dapat menimbulkan ketidakpastian dalam identifikasi mineral pada pasir besi titan. Untuk menghindari hal tersebut, diperlukan suatu metode analisis XRD yang lebih khusus. Tujuan studi ini adalah memperkenalkan metode tersebut yaitu metode analisis pelebaran puncak difraksi Willimason-Hall. Percontoh yang digunakan pada studi ini adalah serbuk pasir besi titan Yogyakarta. Percontoh tersebut dikarakterisasi dengan difraktometer sinar-x (XRD) untuk dianalisis pelebaran puncak difraksinya berdasarkan nilai lebar setengah puncak difraksi (FWHM). Hasil analisis pelebaran puncak ini digunakan untuk menentukan regangan kisi, ukuran kristalit dan probabilitas mineralnya. Dari hasil analisis pelebaran puncak difraksi menunjukkan terdapat empat variasi regangan kisi yaitu 0,0061; 0,0045; 0,0006; dan 0,006 serta tiga variasi ukuran kristalit yaitu 2703, 568, dan 124 nm. Dari keempat variasi regangan kisi dan tiga variasi ukuran kristalit tersebut, didapatkan dua probabilitas mineral bijih (magnetit dan ilmenit) serta tiga probabilitas mineral non-bijih (nefelin, lueneburgit dan albit tingkat tinggi).

Air asam tambang (AAT) adalah air berasal dari tambang atau batuan yang mengandung mineral sulfida yang tersingkap dan teroksidasi akibat dari kegiatan penambangan terbuka. Kandungan sulfat dan logam yang tinggi di dalam air asam tambang mengakibatkan kerusakan lingkungan sehingga diperlukan penanganan khusus. Fitoremediasi dapat digunakan untuk mengatasi permasalahan tersebut sehingga sesuai dengan baku mutu lingkungan air asam tambang. Tujuan penelitian ini ialah untuk mengetahui pengaruh dosis aplikasi fungi mikoriza arbuskular (FMA) terhadap pertumbuhan dan serapan logam tanaman akumulator Typha angustifolia pada air asam tambang. Penelitian ini menggunakan rancangan acak lengkap dengan 4 perlakuan yaitu mo (0 g FMA/ember), m1 (10 g FMA/ember), m2 (12 g FMA/ember), m3 (14 g FMA/ember) dan 4 ulangan, sehingga diperoleh 16 satuan percobaan. Pengamatan yang dilakukan meliputi tinggi tanaman, jumlah anakan, Fe-akar, Mn-akar, Fe-larut, Mn-larut, pH AAT dan hubungan antar peubah pengamatan. Dosis terbaik dalam meningkatkan pertumbuhan T. angustifolia adalah perlakuan m3 (14 g FMA/ember), sedangkan terhadap serapan Fe dan Mn, perlakuan m2 (12 g FMA/ember) dengan nilai indeks fitoremediasi (IFR) Mn dan Fe 98,94% dan 57,93% memenuhi standar baku mutu lingkungan.

Un modelo pedagógico es una recopilación teórica de los paradigmas educativos escogidos por una institución educativa con la finalidad de establecer cuáles son las metas, los métodos y las formas de relación en el ámbito de la enseñanza. La presente investigación trató acerca del paradigma que prevalece en el proceso de enseñanza-aprendizaje en una institución educativa fiscomisional de Manta-Ecuador. En el presente trabajo se evalúa críticamente la aplicación áulica del modelo “Horizonte Pedagógico Pastoral Fe y Alegría Ecuador” declarado como socioconstructivista. El objetivo del estudio es contrastar el modelo pedagógico declarado por una institución en relación con el aplicado en el salón de clases. Por ello los participantes fueron una (1) maestra de parvulario, diecinueve (19) niños y una (1) directora. Se empleó la metodología cualitativa en la modalidad de estudio de caso, desde el enfoque exploratorio. Se aplicaron las técnicas de entrevistas y observación de campo. El análisis fue realizado a partir de las categorías: competencia docente, proceso de enseñanza, proceso de aprendizaje, metodología docente y evaluación. Entre los hallazgos generales se resalta el dominio docente de su área de conocimiento, el control del aprendizaje compartido, el buen manejo del plan de clase, la formación de estudiantes reflexivos, la aplicación de programas educativos extranjeros y la evaluación formativa del aprendizaje. Se concluyó que en el quehacer pedagógico el modelo aplicado es afín al declarado institucionalmente.

Kuala Kangsar is the Royal Town of Negeri Perak. It was established in the 1720s. The name Kuala Kangsar is believed to be derived from the kangsar plant (Hibiscus flocussus) that grows in abundance along the banks of the Sungai Kangsar. Another strong suggestion claims that the name was handed down by explorers and settlers who had established a settlement at the mouth of the river. They called their new home Kuala Kurang Sa, a short form for Kuala Kurang Seratus because there were 99 tributaries that flowed into the Sungai Perak around the area. Kuala Kangsar became famous and remarkable not only because of its title as a royal town but also for its heritage and historical factors. There are a lot of heritage assets in this area. Because of these reasons, Kuala Kangsar has become popular and appealing to attract more tourists. This paper will identify and classify the heritage assets in Kuala Kangsar. The identifications and classifications will be based on some methods which consist of site familiarisation, unstructured interviews, visual observation and literature reviews. After heritage assets identification is done, this paper will develop the Cultural Mapping for Kuala Kangsar where Cultural Mapping is a tool to illustrate all the heritage assets’ location and position in mapping and graphics. Finally, this paper will introduce the Heritage Trail to link all these heritage assets in Kuala Kangsar.
