Abstract

Rompi anti peluru mempunyai fungsi untuk meredam resiko cedera akibat penetrasi proyektil. Proyektil diredam bahkan dihentikan dengan cara menyebarkan energi kinetik sepanjang luasan plat pelindung sehingga energi akibat beban balistik peluru yang diteruskan kepada pengguna semakin kecil. Pada kenyataannya, energi yang diterima oleh pengguna rompi anti peluru masih dapat menyebabkan trauma fisik seperti memar, bengkak atau luka dalam yang cukup serius. Disamping itu, rompi anti peluru konvensional masih terasa berat sehingga mengurangi mobilitas pengguna sehingga perlu dilakukan penelitian tentang material alternatif pengganti rompi anti peluru konvensional yang mempunyai kinerja yang relatif sama dalam menahan energi impact proyektil. Penelitian ini terdiri dari beberapa tahapan, mulai dari studi literatur, simulasi, pembuatan spesimen uji, serta pengujian balistik. Geometri model peluru menggunakan tipe 9 mm Full Metal Jacket (FMJ) yang mengacu pada standar National Institute of Justice (NIJ) 0101.06. level IIIA. Geometri model rompi menggunakan tipe hard body armor sesuai yang beredar di pasaran. Pengujian balistik yang meliputi kriteria Back Face Signature dan energi kinetik mengikuti kriteria yang ditetapkan oleh NIJ 0101.06 baik dalam metode simulasi maupun eksperimental. Simulasi bertujuan untuk mendapatkan konfigurasi ketebalan Hollow Glass Microspheres-Serat sisal dan jumlah lapisan carbon fiber yang memenuhi kriteria standar NIJ 0101.06. Spesimen uji dibuat dengan konfigurasi terbaik hasil simulasi. Selanjutnya, dilakukan pengujian balistik mengacu pada standar NIJ 0101.06. Hasil pengujian spesimen uji dianalisa dan dibandingkan dengan hasil simulasi. Pada penelitian ini didapatkan hasil simulasi model rompi anti peluru dengan konfigurasi ketebalan 6 mm dengan 10 lapisan carbon fiber. Konfigurasi ini menjadi acuan pembuatan spesimen uji dan diuji dengan pengujian balistik sesuai dengan standar NIJ 0101.06. Hasil pengujian balistik spesimen uji I berupa penetrasi proyektil berturut turut sebesar 5,40 mm, 5.26 mm, Back Face Signature berturut turut sebesar ± 10 mm, ± 7 mm dengan menggunakan unit Glock 17 USA peluru kaliber 9 mm FMJ. Hasil pengujian balistik spesimen uji berupa penetrasi proyektil berturut turut sebesar 7.88 mm dan 2.71 mm, Back Face Signature berturut turut sebesar, ± 20 mm dan ± 8 mm menggunakan unit Revolver R1V1 peluru kaliber .38.======================================================================Armor vest has the function to reduce the risk of injury due to projectile penetration. The projectile is muffled and even terminated by distributing kinetic energy along the extent of the protective plate so that the energy from ballistic load that is passed on to the user is getting smaller. In fact, the energy received by armor vest users can cause physical trauma such as bruises, swelling or serious internal injuries. Conventional armor vest still feels heavy because it can reduce user mobility, so research needs to be done on alternative material of conventional armor vests that have relatively similar performance in absorbing projectile impact energy. This research consists of several stages, ranging from literature study, simulation, specimen manufacture, and ballistic test. Geometry bullet model using the type 9 mm Full Metal Jacket (FMJ) which refers to the National Institute of Justice (NIJ) 0101.06 standard Level IIIA. Geometry vest model use the original type of armor vest on the market. Ballistic test criteria such as Back Face Signature and kinetic energy refers to the criteria following the standard that established by NIJ 0101.06 in both simulation and experimental methods. The simulation aims to obtain the configuration of Hollow Glass Microspheres-Sisal fiber thickness and number of carbon fiber layers that meet the NIJ 0101.06 standard criteria. The specimens were made with the best configuration of the simulation results. Ballistic test is based on the NIJ 0101.06 standard. The specimen test results were analyzed and compared with the simulation results. The best result of simulation of armor vest model in this research is 6 mm thickness configuration with 10 layers of carbon fiber. This configuration becomes the reference for the manufacture of specimens and tested by ballistic test according to NIJ 0101.06 standard. Ballistic test results of specimen I in the form of projectile penetration are 5.40 mm, 5.26 mm respectively, Back Face Signature respectively ± 10 mm, ± 7 mm using Glock unit 17 USA 9 mm caliber FMJ bullet. The result of ballistic test of specimen II in the form of projectile penetration of 7.88 mm and 2.71 mm respectively, Back Face Signature respectively, ± 20 mm and ± 8 mm using Revolver R1V1 bullet .38.
