Abstract

The lamp is a lighting tool that is very widely used in everyday life as a means of lighting. The lamp will work or can be used if the lamp is given a power source or voltage. In general, to turn on the lights, we still do it manually, namely pressing the switch as a current or voltage connector for the lamp. However, if done manually it can be an obstacle for those who are busy, so that turning on the lights in their room has difficulty or takes time. Based on the problems above, here the author will design a plate that can be used to make it easier to turn on or control the lights in a room or house. In this case, the author uses a BlueSPP application on the PlayStore using Android Bluetooth and the Arduino interface uses Bluetooth HC-05. This equipment has a working system that is easy for anyone to use, control will be carried out by sending messages from the BlueSPP application via Bluetooth between the Android smartphone and the Arduino microcontroller. When the user sends a message from the BlueSPP Application, the Bluetooth HC-05 will receive commands from the application and forward it to Arduino as a data processor for the message to be instructed to relay whether to turn it on or off. In testing this equipment can work with a maximum range of 15 meters without any obstacles and a maximum work of about 8 meters when there are obstacles.

Abstract

Microbiology practicum activities in tannery process are carried out to determine the causes of leather’s damage caused by microbial activity. This practicum are carried out using media. Practicum activities can be disrupted due to obstructed observations because of bacterial and fungal contamination from the environment. Bacterial and fungal contamination can occur due to sub-optimal media sterilization or improper media storage. The purpose of this study was to determine the effectiveness of the sterilization technique using autoclaves and UV irradiation on NA and PDA media which are often used. The results showed that the media sterilization technique with an autoclave tended to be more effective than UV light sterilization although it did not provide a significant difference. Media without sterilization gives better results. It can be caused by the heating process up to 100 ˚C when making the media. This process can kill most of the microbes present in the liquid media.

Abstract

Softness tester test method is used to test the softness of tanned leather samples, especially for leather that requires a certain flexibility. There needs to be standardization or verification of test methods as re-confirmation in ensuring the test method used. There is verification so that the data produced is accurate and can maintain quality control of the results of the tests. Tanned leather turns limp due to the addition of chemicals. So far, the method of testing for weakness in the physical testing laboratory has never been verified. This study aims to verify the skin elasticity analysis method, it is hoped that the results of the verification can later be used for routine testing. The skin sample used was goat skin for the jacket material. The test was determined using a Softness tester. Parameters of the analysis method used precision, accuracy and testing uncertainty. The results obtained were SD 0.099;%RSD 1.53, a precision value of ≤ 2% can be stated as good precision; accuracy value 99.37%≥95% accuracy value meets the requirements; bias value 0.629. The results of the uncertainty calibration softness 0.0085; accuracy uncertainty 0.057; the combined uncertainty value is 0.058 and the expanded uncertainty value is 0.116. The softness value of the goat skin sample for jacket material was 6.49 ± 0.116, fulfilling the standard quality requirements for jacket material according to SNI 4503:2011. The conclusion obtained by the analyst is that they are able to perform skin flexibility tests according to the SNI ISO 17235:2012 method and this method can be used in the ATK Polytechnic Physical Testing Laboratory.

Abstract

Today, the problem of conventional plastics whose raw materials are derived from petroleum derivatives is still the center of attention because they are difficult to degrade. To overcome these problems, various efforts have been made, one of which is by utilizing bioplastics from natural fibers and starch. The purpose of this research is to fabricate mangrove bark fiber composites with tapioca starch into bioplastics and test their water absorption. Bioplastics were made by melt intercalation method with the addition of glycerol as plasticizer. The resulting bioplastics were characterized by FT-IR and tested for water absorption. The water absorption of bioplastics from fibers without NaOH-soaked was the highest at 5.54%. Bioplastics from and with NaOH immersion had the highest water absorption of 3.59%. Thus it can be said that bioplastics from NaOH-soaked fibers are better than bioplastics from fibers without NaOH-soaked.

Abstract

Penelitian ini bertujuan untuk mengkaji karakteristik produk arang yang dihasilkan dari proses hidrotermal sampah biomassa dan sampah plastik jenis polipropilen (PP). Penelitian tersebut dilakukan pada kondisi subcritical water dengan tiga variasi komposisi. Proses hidrotermal dilakukan dengan menggunakan Batch Type Reactor dengan pemanas utama uap air yang dihasilkan oleh mini boiler dan pemanas eksternal yang diperoleh dari gas burner. Kondisi operasi dari proses hidrotermal dirancang pada tekanan 6 Bar dengan temperatur 160 oC. Parameter yang dikaji dalam penelitian ini adalah berat akhir produk arang, persentase pengurangan massa dan kualitas produk padat yang dihasilkan dari proses hidrotermal. Penelitian juga mengkaji komposisi ideal dari ke tiga variasi yang diujikan. Hasil penelitian menunjukkan bahwa proses hidrotermal sampah biomassa dan sampah plastik jenis PP dapat dilakukan pada tekanan yang lebih rendah dan suhu di bawah 200 oC. Dengan proses hidrotermal pada suhu dibawah 200 ºC dengan tekanan 6 Bar terbukti dapat mengurai sampah plastik dan sampah daun. Hal ini dibuktikan dengan adanya pengurangan massa benda antara 83 % - 86 % dari berat awal dan adanya peningkatan nilai kalor produk. Semakin banyak persentase sampah plastik yang dicampurkan dalam proses hidrotermal maka semakin tinggi nilai kalor yang dihasilkan oleh produk yaitu antara 0,2 % - 6,2 %. Campuran yang paling ideal dari 3 sampel adalah 1:3 (50 g sampah daun dan 50 g gelas plastik). Proses hidrotermal dengan tekanan 6 Bar pada suhu 160 ºC terbukti efektif untuk diterapkan di lingkungan skala kecil.
