Abstract

The facilities used by Posyandu cadres in weighing and measuring the height of children under five are not sufficient, because apart from that, they are not feasible nor are they calibrated accurately. Especially for measuring the height of toddlers, so far the posyandu generally still use the manual method, Based on this background, a digital height measuring device was designed in order to refer to the mission of the Unisma Bekasi Faculty of Engineering in an effort to increase the quantity and quality of community service (PPM) in the field of applied technology (appropriate technology), so this program was implemented. The PPM partners targeted for this program are Posyandu Kemuning cadres, Jatirasa Village, Jatiasih District, Bekasi City. The results of the design of this tool complete the automatic height measurement which is quite satisfactory at the Kemuning Posyandu, Jatirasa Village, Jatiasih District, Bekasi City. Development of a baby height and body mass measurement tool based on the ATmega 8535 microcontroller by utilizing a phototransistor sensor.

Abstract

Abstrak Biokomposit merupakan jenis material yang berasal dari bahan dasar organik dan akan lebih mudah terurai saat menjadi limbah. Banyak produk saat ini bersumber dari komposit, dengan adanya biokomposit tentu saja akan mengurangi jumlah limbah. Pada penelitian ini akan dibuat material biokomposit dengan 2 variasi jenis serat bermatriks Unsaturated Polymer Resin (UPR) dan fraksi volume. Serat yang digunakan antara lain serat ijuk pohon aren dan serat pandan laut. Biokomposit dibuat menjadi empat jenis spesimen dengan perbedaan fraksi volume yakni 5%serat dengan 95%matriks; 10%serat dengan 90%matriks; 15%serat dengan 85%matriks; dan 20%serat dengan 80%matriks dengan metode hand lay – up. Hasil pembuatan biokomposit dilakukan pengujian sifat fisis berupa pengujian densitas, daya serap air dan swelling dan pengujian mekanik dengan uji tarik dan uji impact. Nilai sifat fisis terlihat hampir sama untuk masing-masing serat. Sedangkan untuk sifat mekanik biokomposit serat ijuk menunjukkan kekuatan impact tertinggi dibandingkan serat lainnya, diperoleh pada fraksi volume serat KSI3 yaitu sebesar 30,860 kJ/m2. Pada nilai kuat tarik biokomposit serat ijuk juga dapat menerima tegangan sampai menghasilkan nilai deformasinya sebesar 25,73 MPa. Kata Kunci: Biokomposit serat, fraksi volume, metode hand lay – up, unsaturated polyester resin, uji sifat mekanik, uji sifat fisis. Abstract Biocomposite is a type of material derived from organic base materials and will more easily decompose when it becomes waste. Many products are currently sourced from composites, with the presence of biocomposites of course it will reduce the amount of waste. In this research, biocomposite materials will be made with 2 variations of Unsaturated Polymer Resin (UPR) fiber matrix types and volume fractions. The fibers used include palm fiber fibers and sea pandan fibers. The biocomposite was made into four types of specimens with different volume fractions, namely 5% fiber and 95% matrix; 10% fiber with 90% matrix; 15% fiber with 85% matrix; and 20% fiber with 80% matrix by hand lay-up method. The results of the manufacture of biocomposites were tested for physical properties in the form of testing density, water absorption and thickness expansion and mechanical testing with tensile and impact tests. The value of physical properties looks almost the same for each fiber. As for the mechanical properties of the palm fiber biocomposite, it showed the highest impact strength compared to other fibers, obtained in the volume fraction of KSI3 fiber, which was 30.860 kJ/m2. On the tensile strength value of the palm fiber biocomposite can also accept stress to produce a deformation value of 25.73 MPa. Keywords: Fiber biocomposite, volume fraction, hand lay-up method, unsaturated polyester resin, mechanical properties test, physical properties test.

Abstract

Pengelasan Austenite Stainless Steel atau baja tahan karat jenis Austenite sering mengalami korosi yang diakibatkan terbentuknya ferrite dengan persentase tinggi sehingga memicu terjadinya korosi. Pada pengelasan stainless steel digunakan backing gas untuk menghambat kontaminasi kotoran dari lingkungan sekitar masuk ke dalam logam las dan menyeimbangkan fase austenite-ferrite sehingga menghambat proses carbide chrome. Di pekerjaan lapangan penggunaan backing gas menggunakan gas Argon dan dilakukan hanya pada daerah akar las, sedangkan proses oksidasi tetap terjadi saat proses pengelasan daerah hot pass hingga capping. Penelitian ini bertujuan untuk menganalisis pengaruh variasi backing gas terhadap nilai kekerasan dan hasil struktur mikro pada baja tahan karat austenitic 316L. Pada penelitian ini dilakukan pengelasan metode GTAW dengan logam induk baja tahan karat austenitik type 316L ketebalan 4mm dengan tipe sambungan V, dengan memvariasikan flowrate pada backing gas Argon pada masing-masing proses pengelasan. Setelah proses pengelasan dilakukan pengujian Non Destructive Test Radiography untuk mengetahui hasil fisik dari pengelasan menggunakan variasi flow rate pada backing gas Argon tersebut, pengujian metalografi dengan mikroskop optik dan uji kekerasan. Hasil pengujian menunjukan bahwa dengan memvariasikan flow rate pada backing gas menggunakan Argon (AR) menghasilkan adanya proses pelapisan nitriding CR pada material hasil las GTAW. Penambahan flow rate pada backing gas menyediakan pereduksi yang dapat melindungi atau menetralkan pertumbuhan oksida yang lebih efekstif pada pengelasan material austenic stailnless steel. Serta dapat memperbaiki hasil uji Hardness Test dan Microstructure terhadap material tersebut. Sehingga dapat dinyatakan dengan memvariasikan flowrate pada backing gas Argon dapat diterapkan pada pengelasan GTAW
