This study aims to analyze the resistance on vessels that have a single hull shape of the hard-chine type is modified to a multi-chine types using the "DELFTShip" method. This research includes research on the development of the "DELFTShip" method using a speedboat sample of the Vocational School - Undip, where the ship plans to be modified on the hull that was originally hard-chine to multi-chine, with a qualitative approach using the "DELFShip version 4.03.68" method which can later be known differences in the value of ship resistance (RT).Results showed that the resistance value (RT) at a speed of 3 knots there is a difference -0.0332 kN, at a speed of 4 knots there is a difference of 0.0925 kN, and at a speed of 5 knots there is a difference 0.3205. By referring to the number of Froude Number. , stomach with multi-chine type has the value of prisoner (RT) is better than the stomach with hard-chine type.

The laboratory is a workplace that has potential hazards both physical, chemical, biological, and ergonomic hazards. Potential hazards in educational laboratories are considered lower than in industrial laboratories because they use relatively smaller amounts of material. This results in financial losses, injuries and damage to equipment and infrastructure. Some theories state that accidents that occur at work are the result of mistakes from humans and management. This paper discusses how to arrange and implement Occupational Safety and Health programs in educational laboratories so that potential hazards can be controlled and minimize workplace accidents.

Metode Penyimpanan Bakteri Xanthomonas Oryzae pv. oryzae Penyebab Penyakit Hawar Daun Bakteri Pada Tanaman Padi Menggunakan Glycerol Santi Sariasih; Fitri Widiantini; Wiwin Widiawati

The existence of Xanthomonas oryzae pv. oryzae, the bacteria which causes Bacterial Leaf Blight of rice, is really necessary for the laboratory to support the research activities of the phytopathology experts. Long-term preservation by using glycerol under -20°C can be conducted to preserve the culture’s availability to stay viable in the laboratory. This research aimed to determine the glycerol concentration that is able to preserve the viability and pathogenicity of Xanthomonas oryzae pv. oryzae bacteria after being preserved for 3 and 6 months. This experiments were performed using Completely Randomized Design which comprised of six treatments and four replications, they were: glycerol 50%, 40%, 30%, 20%, 10%, and control (without glycerol). The results of this study showed that viability of Xanthomonas oryzae pv. oryzae that was preserved within 20% glycerol solution for 6 months was different compared to control group. The number of Xanthomonas oryzae pv. oryzae bacteria on 20% glycerol was 4,49 x 109 CFU/ml, while on control group was 1,76 x 109 CFU/ml. 20% glycerol concentration had significant effect on the Bacterial Leaf Blight symptoms’ length after 6-months preservation that observed on the 7th day after incubation. The Bacterial Leaf Blight symptoms’ length on 20% glycerol treatment group was 46,2 mm and 22,7 mm on control group. Meanwhile for the 3 months preservation, the administration of glycerol did not show any significant effect on the Xanthomonas oryzae pv. oryzae’s viability and the Bacterial Leaf Blight symptoms’ length.

Rancang Bangun Mesin Laser Engraver and Cutter Untuk Membuat Kemasan Modul Praktikum Berbahan Akrilik Aris Eko Saputro; Mochammad Darwis

In the competence of vocational institution, lecturers, students and PLP staff are expected to make their own appropriate equipment. An educational laboratory as a place to provide adequate practice and supporting equipments. Equipment or innovations that are designed must be packaged in an attractive form as a prototype of a product. As for the research and or as a practical tool in the laboratory. The packaging also serves to protect the device made and increase its life time. Usually the material used to make a casing material is acrylic. The thicker the acrylic, the more difficult it is to make. Laser engraver or laser cutter as a solution to facilitate the manufacture of casings that made from acrylic. User will create a two-dimensional design using a program, such as Inkscape. Then the design is saved or changed into gcode. The resulting gcode file is then sent to the laser engraver to make the design. The power of the laser head used, will determine the thickness of the acrylic to be cut. In this research, 2 mm thick acrylic was tested using a 15W laser diode module.

Penambahan Fitur Tampilan LCD dan Micro SD Card Reader pada mesin Laser Engraver and Cutter di Laboratorium Pengemudian Listrik Mochammad Darwis

Laser engraver and cutter machine that have been made in previous research, can only be controlled by a computer. The addition of LCD display and Card Reader will make it work alone without using a computer (offline). Card reader is used to read gcode files from 2-dimensional design that have been made on a computer. LCD display is used to display a menu or a list of existing settings, the percentage of loading data from a gcode file and displays the 2-dimensional design of the gcode file. To move the menu on the LCD display an encoder switch is used. This additional feature was created using a microcontroller STM32F1 type as a core control system which performs serial communication with a laser machine. 32 bit ARM microcontroller is used because a lot of tasks has to perform. It must be able to read data from the SD card, display the image form from the gcode file and send it to the laser machine. Compared 3 types of gcode file of different file sizes and the speed of loading the data. The laser machine can perform its function by using the controls of the additional feature modules that have been made.

Penanganan berbagai Tingkat Kelengketan pada Alat gelas di Laboratorium dari Pengaruh Basa kuat Larutan NaOH beserta Ujinya Sri Harjanto; Indra Gunawan

As PLP (Educational Laboratory Institution) or other laboratory personnel for their daily work, they are very closely related to the tools and materials in the laboratory scope, and cannot be separated from laboratory equipment in the form of instruments or glassware. The problem here is that there are times when we encounter glassware in the scope of a laboratory whose faucet is closed or the faucet cannot be opened because it is sticky, and on average it is used after using NaOH base solution. That is why we are here to try to do a test to find out how much the stickiness of a device made from glass raw materials. By using variable various levels of concentration of NaOH solution with different time periods. As a decay the detergent solution is also used in various levels of concentration and heating. . From the data of the stickiness level test results using variable concentrations of NaOH solution and detergent solution will get the results that with the increasing concentration of NaOH solution, the stickiness will also be stronger. Likewise with the passage of time the longer the NaOH solution comes into contact with materials made of glass, the harder it will become and the stickiness will also be stronger so that it will be more difficult to be released. while on a strong adhesiveness will be more effective when using the immersion method at a temperature of 60-70 ° C.
