Abstract

Abstrak. Mesin Dry Leak Test adalah alat yang digunakan untuk menguji kebocoran pada suatu komponen tanpa menggunakan cairan. Nozzle merupakan komponen yang paling berpengaruh pada mesin dry leak test karena mendistribusikan aliran udara pada komponen yang akan di uji. Pada penelitian ini dilakukan rancang-bangun mesin dry leak test dengan nozzle dan dies spesifik yang akan digunakan pada lampu reflektor mobil Avanza. Kemudian pengujian performa mesin dilakukan dengan memvariasikan lubang outlet nozzle dengan dimensi Ø 2/3/4 mm dan tekanan input pada rentang 1 – 5 Bar. Diameter outlet 2 dan 3 mm memiliki perfroma yang baik hingga 3 Bar. Sedangkan dia. 4 mm hanya bisa digunakan pada tekanan 1 Bar.Abstract. The Dry Leak Test Machine is a tool used to test components for leaks without using liquid. The nozzle is the component that has the most influence on the dry leak test machine because it distributes air flow to the component to be tested. In this research, the design and construction of a dry leak test machine was carried out with a specific nozzle and dies that will be used on the reflector lights of the Avanza car. Then machine performance testing was carried out by varying the nozzle outlet hole with dimensions Ø 2/3/4 mm and input pressure in the range 1 – 5 Bar. Outlet diameters of 2 and 3 mm have good performance up to 3 Bar. Meanwhile dia. 4 mm can only be used at 1 Bar pressure.

Abstract

Banyaknya sampah plastik membawa dampak negatif untuk kesehatan dalam jangka panjang, seperti kanker, dan pencemaran lingkungan karena sulit terurai oleh tanah, sehingga perlu proses daur ulang yang sbeelumnya dicacah terlebih dahulu. Penelitian ini bertujuan untuk menginvestigasi proses perancangan hingga pengujian performa mesin pencacah sampah tipe crushing dengan bilah monolitik ganda yang parameter ujinya kualitas hasil cacahan karena pengaruh kecepatan putaran bilah dan jenis/tebal sampah yang belum diteliti sebelumnya pada tipe bilah ini. Pengujian dilakukan secara eksperimen. Dari hasil perancangan, didapatkan hasil estimasi kebutuhan daya motor adalah berkisar 3,8 hp dengan Safety Factor dari rangka sebesar 15. Bilah yang dibuat, dihasilkan dari pembubutan benda kerja poros besar utuh dan dibentuk sesuai pola dari gambar kerja. Sedangkan hasil pengujian menunjukkan bahwa jenis atau tebal sampah lebih berpengaruh pada dimensi hasil cacahan, dengan hasil cacahan terkecil dihasilkan dari jenis sampah industri, akrilik dengan dimensi 2,72 mm – 31,78 mm. Sedangkan waktu yang dibutuhkan untuk mencacah 500 gram plastik berkisar 1 menit..

Abstract

Huller is the main machine that determines the quality and quantity of production in the rice milling industry. The current problem, especially in the small-scale rice milling industry, is that they still use locally made huller machines that use 6-inch diameter rice rubber rollers with a capacity of 800-1,200 kg/hour. Local huller machines produce a yield (broken rice) of 30-40%, so three huller machines and one polisher machine are needed in one production line. This machine assembly requires energy, human power and high costs. With these problems, a machine is needed that is capable of increasing the yield and milling capacity. Huller machine with horizontal rice rubber roller has a dimension specification of 1.3X0.9X2 meters; Rice rubber roller diameter 10 inches; 3 phase electric motor 20HP 15KW 1,500 rpm. The huller machine has been tested at the CV. Putra Maju rice mill, Wirakanan Village, Kandanghaur District, Indramayu Regency for 4 months. Test results Huller machine capacity 1,600 kg/hour ± 50 kg with a yield of 72% ± 2%.

Abstract

Garam merupakan salah satu komoditas yang strategis karena sangat dibutuhkan oleh orang banyak. Peningkatan kebutuhan terhadap garam di Indonesia semakin meningkat berbanding lurus dengan meningkatnya jumlah penduduk dan jumlah industri besar pengolahan garam di Indonesia. Terjadinya impor garam karena peningkatan kebutuhan dan kegunaan garam pada industri dan rumah tangga. Salah satu kota/kabupaten yang  menjadi sentra penghasil garam kedua setelah Cirebon adalah Kabupaten Indramayu. Kabupaten ini mampu mensuplai kebutuhan garam nasional. Perancangan alat bantu pengerik garam   yang   diperuntukkan   untuk   petani   garam   di   Kabupaten   Indramayu   diharapkan   mampu menggantikan alat konvensional yang saat ini sering digunakan digunakan petani garam. Sistem kerja alat ini adalah dengan menggunakan mekanisme roda gigi payung dan lurus sehingga mampu secara axial memutar alat pengerik yang dirancang seperti sikat. Berdasarkan hasil perhitungan, roda gigi yang dibuat untuk memenuhi kebutuhan alat bantu ini adalah roda gigi dengan modul 2, jumlah roda gigi 20 dengan ketebalan roda gigi adalah 40 mm. Tenaga dan beban yang dikeluarkan oleh petani bisa berkurang hingga 50% dari alat konvensional yang biasa digunakan saat ini. Analisis kekuatan dan safety factor terhadap alat  ini  telah  dilakukan  menggunakan  FEA  (Finite  Element  Analysis)  dengan  bantuan  software solidworks. Hasil analisis menunjukkan bahwa roda gigi payung yang digunakan cukup kuat untuk mengerik garam untuk kedalaman 50 mm.

Abstract

The study of grammar at Darul Ihsan Boarding School addresses several issues identified by the researcher, including a decline in student enthusiasm, discomfort, lack of interest in the subject matter, and weak collaboration among students. Additionally, teachers face the challenge of insufficient time to present the material comprehensively and adequately, leading to a decrease in students' academic achievement. This research aims to explore the implementation of the Numbered Heads Together (NHT) method using presentations in grammar instruction and to evaluate its effects and students' responses. The research employs an action research methodology, targeting a population of 1,307 students. The sample consists of 20 first-grade high school students from class 1C. The researcher utilized observation sheets, questionnaires, and tests for both the first and second phases as research instruments. The findings indicate that the teaching and learning process during the first phase, according to the implementation plan, achieved a rate of 58% (acceptable), while the second phase achieved a rate of 92.3% (very good). Students' proficiency in grammar improved, with an average score of 58 in the first phase (acceptable) and 74.5 in the second phase (good). Additionally, 94.5% of students responded positively, with only 5.5% negative feedback, indicating a generally positive student response.

Abstract

The students of MIN 1 Kota Banda Aceh often face difficulties in understanding Arabic vocabulary due to the limited use of effective teaching methods, which leads to low motivation and boredom in learning. This study aims to examine the effectiveness of using the Tic Tac Toe game as a teaching aid to improve students’ Arabic vocabulary and to identify their responses to this method. A quasi-experimental design was employed, involving both experimental and control groups, with pre-tests, post-tests, and a questionnaire as data collection tools. The findings indicate that Tic Tac Toe is effective in enhancing students’ vocabulary mastery, as shown by the independent t-test results using IBM SPSS Statistics 22 with a significance value of 0.01 < 0.05, confirming the acceptance of the alternative hypothesis. Furthermore, the students’ responses were highly positive, with 97% indicating favorable attitudes toward the use of Tic Tac Toe in learning Arabic vocabulary.
