Abstract

An alternative excavation of natural materials that could potentially be used as a substancedyes, continue to be made, including the skin of red dragon fruit. Because the red dragon fruit latelya lot of public interest, skin which amounts to 30-35% is often just discarded as waste only.In an effort to use the red dragon fruit peel waste that is not optimal, to increase the economicvalue of the skins of red dragon fruit and power use for the community.The goal is to mengetehaui type of pigment and pigment quality of dragon fruit red on someshelf with different types of solvents.This research used Randomized Design Group (RAK) Factorial consisting of two factors I;comprised of over 4 levels; factor II consisted of 3 level. Factor I: The Fruit Store (S), fresh (day0), the shelf life of fruit 2 days, 4 days and 8 days, whereas the second factor: the type of solvent(L), namely aquades; combination aquades and citric acid (9:1), and a combination Eeanol 1N andcitric acid (9:1).The results showed that the skin of red dragon fruit (Hylocereus costaricensis) containinganthocyanin type ramnosil sianidin 3-glucoside 5 - glucoside, based on Rf values (retrogradationfactor) of 0.36 to 0.38 and maximum absorbance at a wavelength with ë = 536.4 nm. Combinationtreatment S2P2 (the shelf life of fruit 4 days with solvent water and citric acid) produce anthocyaninpigments of red dragon fruit skin with the best quality, with a pH value of 1.91; the brightness (L)25.60; level of redness (a +) 6.97; the yellow (+ b) 0.50, 0.363 pigment absorbance; levels ofanthocyanin 1.1 mg/100ml; total dissolved solids 66.52% and 10.02% yield.

Abstract

One of centrale of home industry in Malang is UD. BJ Mendit on Mendit Barat, Kec. Pakis withit?s roof production process. From the observation that the researcher do into UD. BJ Mendit,finded that the production process had been doing often with technical and non technical problemsthat make some failed roof product. Purposes of this research are identifying types of roof failedproduct, analysing main cause of roof failed product with Pareto diagram. From the steps had done,finded that the biggest failed criterion is keropos. Keropos is caused by lack of skill and correctnessof worker on processing the raw material, can also caused by process execution which not fullycorret so that produce critical process to be repaired first to increase the quality of Mendit?s roof.

Abstract

Las SAW merupakan bentuk pengelasan yang banyak digunakan untuk fabrikasi pipa, misalnya pipa spiral. Luasnya pemakaian las SAW disebabkan karena pengelasan dapat dilakukan secara otomatis dan memiliki keandalan yang tinggi. Ketangguhan las dipengaruhi oleh banyak faktor diantaranya masukan panas, kuat arus, filler dan fluks, kecepatan las dan laju pendinginan. Tujuan dari penelitian ini dimaksudkan  untuk mendapatkan struktur mikro berupa ferit acicular yang dapat memberikan kekuatan tinggi dan nilai kekerasan yang rendah dari sambungan las. Hal ini dilakukan dengan membuat variasi  heat input pada pengelasan.  Percobaan dilakukan menggunakan bahan Baja API 5L X-52 dengan variasi kuat arues pada arus DC 800 Amper, 825 Amper, 850 Amper, 875 Amper and 900 Amper pada pengelasan pipa spiral di bagian luar, dengan kecepatan pengelasan 13,67 mm/s dan Tegangan 35 volt. Pengujian meliputi pengamatan mikro struktur dan ketangguhan.  Hasil penelitian menunjukkan bahwa semakin tinggi penggunaan kuat arus dapat meningkatkan jumlah presentase ferit acikular dan meningkatkan nilai ketangguhan.

Desain dan Pembuatan Inkubator berdasarkan Distribusi TemperaturBudionoStaf Pengajar Jurusan Teknik Mesin, Fakultas TeknikUniversitas Muhammadiyah Malang Email : budiono_ssi_mt_umm@yahoo.comABSTRACTWhen a new born babies (especially premature babies) have not been able to adjust to the temperature  outside.  One  of  the  standard  post-neonatal  procedures  are  all  newborns  should  be incorporated into the incubator, the time it takes depends on the level of health, durability and infant organ system itself. In this case the infant incubator is one tool that can help the newborn to adapt with the outside world, because the conditions in the womb to the outside world is very different, especially at a temperature problem. So with regular heating system so the baby can adapt to the transition period.Therefore, newborns should be helped to adjust to the new environment by putting them into the incubator. Infant incubator temperature is slowly lowered so that it can make the baby feel comfortable. In order for your baby comfortable at room temperature, then the distribution must evenly in incubator. To determine the pattern of temperature distribution in the incubator at my research will provide solutions to design and create an  incubator temperature distribution based on the simulation results based on numerical approach with Matlab programKeywords: incubator, distribution, matlab
