Abstract

Tulisan ini merupakan kajian pustaka yang mengkaji fatwa pelarangan mahar hafalan al-Qur?an. Sebagai alat analisis teori al-urf sangat tepat digunakan untuk memadukan kesenjangan tradisi yang berkembang dengan fatwa pelarangan tradisi tersebut. Tulisan ini mengkritisi fatwa tersebut dan menyimpukan; Pertama, fatwa mengedepankan aspek teoritis dan kurang memperhatikan aspek praktis yang tengah terjadi pada masyarakat. Kedua, metodelogi istinbat dalam berfatwa yang dilakukan adalah mengutamakan dalil-dalil muttafaq serta menomerduakan dalil-dalil mukhtalaf, sedangkan al-urf terkategori pada mukhtalaf sehingga kurang diperhatikan. Ketiga, Penulisan teks fatwa yang ada dianggap sangat singkat dan memerlukan kajian lebih lanjut agar memperoleh pemahaman dari maksud dari fatwa tersebut, sehingga menimbulkan kegamangan dan berpotensi menimbulkan silang pendapat. Keempat, prinsip fatwa yang digulirkan adalah berlepas dari mazhab tertentu, hal ini dianggap tidak sejalan dengan apa yang direkomendasikan oleh fukaha dan jauh dari mengayomi, karena proses beragama suatu masyarakat hendaknya memulainya dengan mengikuti mazhab tertentu agar tidak salah arah, dan tetap di dalam koridor keislaman yang benar. [This paper criticizes the fatwa on the prohibition of memorizing the Qur'an. As an analysis tool, al-urf theory is very appropriate to be used to integrate the growing of tradition gap with the fatwa prohibiting that tradition. This paper concludes; First, the fatwa emphasizes the theoretical aspects and pays little attention to the practical aspects that are happening to the community. Second, istinbat methodology in performing the obedience carried out is to prioritize the arguments of muttafaq as well as to put forward the arguments of the mukhtalaf, while the al-urf is categorized in the mukhtalaf so that it is heedless. Third, the writing of the existing fatwa text is considered to be very high and requires further study in order to gain an understanding the purpose of the fatwa, thus causing confusion and the possibility of the conflict. Fourth, the fatwa principle that is rolled out is not depend on a certain schools, by contrast with the recommendation of the jurist, because the religious process of a community should start by following the certain schools in order to remain stay in the Islamic pathway].

Abstract

Gasification is a technology for converting solid biomass into syngas. Corn cobs biomass is converted into pellets to obtain more homogeneous fuel. The downdraft gasifier type is used to have low tar content. The research was conducted to see the effect of the ratio of air and ER on the reactor temperature and the gas composition of CO, H2 and CH4. For pyrolysis and oxidation zones, air enters with variations (AR.Pir-Ox), namely 0%; 70%; 80%; and 90% in the intake air 14.5; 19.3; and 24.1 Nm3 / hr of E.R 0.3, 0.4, and 0.5. The air intake for each zone is regulated using a tap. Temperature measurement using type K thermocouple. Downdraft reactor performance is obtained by looking at the syngas content in CO, H2, and CH4 meters. The results showed the effect of AR.Pir-Oks with an air input of 24.10 Nm3 /h with E.R 0.5 having the highest temperature of 910oC, in the oxidation zone. This stratified air input plays a role in increasing the temperature along the altitude zone. The increase in the introduced oxygen produces an increase in heat. Syngas production in an air flow of 19.3 Nm3 / hour with a ratio of 90% pyrolysis and oxidation zone (ARPir-Oks), is the reactor produces gas products with a composition of 22.5% CO, 0.96% CH4, and 15.55 H2 %. The results of this test prove that the air entering the pyrolysis zone can provide additional syngas composition.

Abstract

Biomass is one of the agricultural wastes that can be used as a substitute for alternative fuels. The biomass needs to be converted into briquettes first, so that it becomes an environmentally friendly fuel. Corn cobs and rice straw are the most common types of agricultural products found in East Java, therefore the potential for alternative fuels that will be obtained will also be higher. This research aims to determine the characteristics of solid fuels (briquettes) including: calorific value of briquettes, water content of briquettes, ash content of briquettes and drop test on briquettes using a mixture of corn cobs and rice straw. The variation of the mixture between corn cobs and rice straw is 1 kg, where 1 kg of corn cobs and straw using a mixture ratio of 90%:10%, 80%:20%, 70%:30% and 60%:40% using starch adhesive of 0.001 kg. In addition, it uses two pressure variations, namely: A = 2500 kPa and B = 5000 kPa which are used in briquettes. The results of the research on the characteristics of briquettes such as: The highest calorific value using a mixture of 90% corn cobs and 10% rice straw was obtain at 5546.74 cal/gram. The most optimal moisture content using a suppression load of 5000 kPa using a mixture of 90% corn cobs and 10% rice straw obtained a value of 11.30%. The optimal ash content produced also uses a suppression load of 5000 kPa by using a mixture of 90% corn cobs and 10% rice straw to obtain a value of 20.58%. While the drop test on briquettes using a pressing load of 5000 kPa by using a mixture of 60% corn cobs and 40% rice straw obtained a value of 11.10%, a large reduction in particle size when applied from a height.

Abstract

One of the main problems occurring on this earth is air pollution and the reduction in the amount of fuel oil. The main aim of the research is to regulate the mixture of fuel and air so that it burns ideally, so that the resulting emissions are non-toxic and environmentally friendly. This research is a technological development as a means of information and comparison before and after a supercharger is installed. Adjust the AFR (Air Fuel Ratio) value through the inlet air channel to obtain the ideal ratio of fuel and air so that the mixture becomes stoichiometric. The air intake is regulated into the engine by adding a supercharger using the Proportional Integral Derivative (PID) control method. The supercharger works by using a lambda sensor as data input for a poor or rich mixture, then the lambda sensor value is entered into the PID method. The PID value will determine the speed of the brushless motor which aims to obtain stoichiometric AFR. A lambda sensor that is close to the 0.5 setpoint is expected to produce a more ideal mixture of air and gasoline.Keywords: Management Information, Supercharger, Proportional Integral Derivative, Automatic Motorcycles.

Abstract

The millennial generation lately, many who give dowry marriage outside the habits of society in general (a set of prayer tools or rings), but dowry in the form of memorization of the al-Qur’an. The opinion that developed at this time was that the dowry was more stable and primary compared to other dowries. There are concerns about the loss of women's rights because the dowry is not material. Then the giving of the dowry for memorizing the al-Qur’an needs to be reviewed with an appropriate legal formulation. Responding to this phenomenon, the Saudi Arabian fatwa institute also issued a fatwa related to the ruling on memorizing the al-Qur'an. This research is a literature review using an empirical juridical approach, while the data collection method was done through documentation and interviews. This study found that the phenomenon of giving the Dowry memorization of the al-Qur’an was a problem that had occurred during the time of the Prophet, but has reappeared lately with opposing motives and backgrounds. Then the purpose of this study is to bring up and clarify the legal status of the phenomenon. The results showed that the law of giving dowry in the form of memorizing the al-Qur'an was not permitted. Keywords: Dowry, Memorization of the Qur'an, Al-Lajnah al-Daimah Li al-Buhus al-IlmiyahWa al-Ifta.

Abstract

Corncobs were agricultural waste, while sawdust was waste of furniture industries.  Both materials can well decomposition naturally, but it was still time-consuming. The aim of this research to provide both wastes by converting them into sustainable and worthwhile solid-fuels briquettes format. In this research, variation of mixture ratio of corn cob powder and sawdust in briquettes used was 50:50, 60:40, 70:30, 80:20, and 90:10. 1:1 ratio of tapioca starch and water was used as the adhesive to bond the briquette mixture well. Compaction process used hydraulics by 2 tons pressing load. Testing of physical characteristics includes calorific value, moisture, and ash content. The lowest calorific value was 4589.94 kCal/g, which was achieved in the 50:50 mixture of corn cob and sawdust. The highest calorific value was 6579.87 kCal/g, which was achieved in the combination of a corn cob and sawdust ratio of 90:10. The calorific value continued to increase with more mixture of corn cob. Highest moisture content was 20.00%, achieved in 50:50 combination mixture of corn cob and sawdust. Moisture content decreased as the ratio of corn cobs used in the briquettes increased, with the lowest content obtained at 8.88% using a 90:10 mixture of corn cobs and sawdust. Highest ash content on this research 16.85%, was achieved in the 50:50 combination of corncob and sawdust. Ash content also tended to decrease with the increase of corn cob powder used in the briquettes. Lowest ash content was obtained at 10.10% using a mixture of corn cob and sawdust 90:10.

Abstract

The design itself consists of various points of view called The Four C's of Design, namely: Creativity, Complexity, Choice, and Compromise. The Jominy Test tool is a tool for testing the hardenability of steel which is carried out by a cooling process (Quenching). The planning of the jominy test tool (Hardenability Jominy Test) is based on the ASTM A255 standard. Testing the semi-automatic jominy test tool on variations in valve openings against pressure height gets an average result, namely a valve opening angle of 15 ° as high as 0 mm, 30 ° as high as 5.3 mm, 45 ° as high as 27.3 mm, 60 ° as high as 48.3 mm, 75 ° as high as 62 mm, and 90 ° as high as 85 mm. This test shows that the greater the valve opening angle, the higher the water jet emitted. The height of the water jet has passed the desired standard of 63.5 mm, so that the valve angle reference can be taken between the angles of 75 ° and 90 °. The closest angle to the height of 63.5mm is 75° as high as 62mm, so to determine the height of 63.5mm to increase the angle. In the experiment conducted using angles of 76°, 77°, and 78°. The results obtained are at an angle of 76° as high as 63.5mm, 77° as high as 64°mm and 78° as high as 64.5°mm.

Abstract

Mahar merupakan pemberian dari mempelai pria kepada wanita yang berupa materi, baik berupa seperangkat alat salat, cincin, uang atau barang berharga lainnya. Belakangan ini hafalan al-Qur’an juga kerap digunakan sebagai mahar pernikahan, dengan berbagai alasan; mahar yang meringankan, mengikuti tren, dan keinginan pribadi. Fenomena ini tidak sama dengan kasus Sahl bin Said al-Sa’idi. Tinjauan hukum Islam, dan teori maqasid al-syariyah sangat tepat digunakan dalam menentukan kepastian hukum dari fenomena tersebut. Penelitian ini merupakan kajian pustaka (library research) dengan menggunakan metode deskriptif analisis.
