ARDUINO BASED SOIL STRUCTURE DETECTOR USING GEOPHONE Rizki Ardianto Priramadhi, Candra Adi Sishananto, Muhammad Ary Murti Electrical Engineering, Telkom University Abstract Because of technology development, the needs for energy is also getting bigger, energy exploration in the earth continues to be carried out in order to meet the worlds energy needs. A tool that can detect soil material before drilling is needed. Each material has a different density, the difference in density produces a back effect A geophone is a transducer that converts seismic energy or vibration into an electric voltage that can be measured accurately, the results obtained can be recorded in a recording station. Simply stated, this occurs from the mass vibrations that are coiled around a wire and are in a magnetic field, when a vibration occurs, the mass will move at a certain speed and produce an electromotive force that can be read with a simple voltmeter. Geophones can be used to detect differences in material that is below the surface of the ground. This is done by carrying out artificial vibrations and receiving these vibrations with the geophone. To measure the vibrations that will be captured by the geophone, it begins by arranging the geophone configuration to be placed in a straight line with the wave source. The data obtained from the survey is the wave travel time from the source to each geophone indicated in the wave traces. In this research, we obtained that a geophone sensor can read the speed of waves in passing through a medium. Each medium produces a different speed - the more dense the density of the medium, the faster the velocity of the wave propagation through it. In this final project the fastest is split stone with 1.62ms, brick is slightly slower with 4.02ms, and sand is the slowest with 15.86ms.

EVALUATION OF ERGONOMY AND LABORATORY ENVIRONMENT SANITATION ON THE PRODUCTIVITY OF STUDENT PRACTICUM RESULTS Dwi Atmanto Engineering Faculty Universitas Negeri Jakarta Abstract Abstract. Often the factors of human ability and limitations are not given enough attention, as long as reaching the production target the problem is solved. Consistently, the increase in the number of work accidents and occupational diseases is due to the lack of attention to the work environment that affects human activities in the workplace. Most focus on research and high technology rather than practical action in the workplace. The Ergonomics approach helps increase productivity and prevent work accidents, with practical action in a place where many people work. Ergonomics is not only implemented for product design, work facilities or work places / environment with the aim of increasing effectiveness, efficiency and work productivity. It is also applied to improve the comfort, health and safety of human workers. In this study the ergonomics approach will focus on evaluating work systems, both physical physical work problems (manual lifting, repetitive motion, lighting, noise, and expanded energy) as well as the physical conditions of the work environment (temperature, humidity, air circulation, lighting, noise, mechanical vibrations, odors, and colors) using the Ergonomic checklist Keywords: ergonomic, sanitation of laboratory, practicum productivity Share Link | Plain Format | Corresponding Author (Dwi Atmanto)

Maggot Oil as a Feed Supplement for Reducing Methanogenesis of Rumen Microbial Culture In Vitro Anuraga Jayanegara, Dwitami Anzhany, Despal Department of Nutrition and Feed Technology, Faculty of Animal Science, IPB University, Bogor 16680, Indonesia Abstract Hermetia illucens larvae or known as maggot contains considerable amount of oil in its body. The oil is rich in energy and C12:0 fatty acid (lauric acid), making it promising to be used as a multi-functional feed supplement. This experiment aimed to evaluate the use of maggot oil as a feed supplement for reducing methanogenesis of rumen microbial culture in vitro. Maggot was extracted for its oil by using hexane in a Soxhlet apparatus. The oil was supplemented into a feed substrate that consisted of forage:concentrate mixture (3:2 w/w). Supplementation was performed at different levels, i.e., 0, 1, 2, 3, 4 and 5% from substrate dry matter. An amount of 0.75 g substrate was mixed with 50 ml McDougall buffer solution and 25 ml rumen fluid (containing various rumen microbes such as bacteria, protozoa, anaerobic fungi and archaea methanogen) in a 125 ml serum bottle. All incubation bottles were tightly closed and incubated for 24 h in a water bath that maintained at 39oC. Each treatment was incubated in three replicates (duplo per replicate). Parameters measured were gas production kinetics, methane emission, volatile fatty acid (VFA), ammonia, protozoa population, and organic matter digestibility (OMD). Results revealed that maggot oil at 4 and 5% supplementation level was able to reduce methane emission by 20.7 and 26.9% (P<0.05) in comparison to control, respectively. However, its supplementation at 3% or lower did not alter the methane emission. The OMD parameter was linearly reduced with increasing level of maggot oil supplementation (P<0.05), but VFA was not affected. In contrast to our expectation, maggot oil at 3 to 5% increased log protozoa population and ammonia concentration than those of control (P<0.05). In conclusion, maggot oil may serve as a promising supplement for mitigating ruminal methanogenesis and the effect is dose-dependent.

VARIOUS FORM OF LIVING BEINGS NICHE AS INDICATORS OCCURING CLIMATE CHANGE Dwi Atmanto Engineering Faculty - Jakarta State University Abstract Abstract The negative effects of global warming will affect most living organisms, including plant disease pests. Climate variables such as temperature, rainfall, humidity, and gas atmosphere will interact with living things / plants in various ways with various mechanisms. Changes in temperature and concentration of CO2 affect living things / plants directly in terms of tissue and photosynthesis allocation of specific organs and indirectly through changes in geographical distribution and population dynamics of plant disease pests. Increased temperatures will cause insects / pests to become more abundant, there is a strong link between outbreaks of plant pest and climate variability. The model of the relationship of climate parameters with pest attacks of plant diseases can be used as an early warning adaptation technology to prevent the occurrence of pest attacks, so that crop losses can be reduced. The concept of this paper is the importance of building early warning of pest attacks based on climate equation models with OPT attacks, so that climate prediction data can be utilized, and yield losses due to OPT attacks can be suppressed. In addition, in order for the system to develop and be sustainable, the development of an early warning system needs the integration of several related agencies.

DESIGN OF RIVER NATURALIZATION IN SUSTAINABLE WATER MANAGEMENT EFFORTS Dwi Atmanto Engineering Faculty - Jakarta State University Abstract Abstract. Ciliwung River and Citarum River which flows almost throughout the City of Jakarta and West Java, this river functions as a drainage channel in Jakarta and West Jaa, but as the population grows on the banks of the Ciliwung River there are many densely populated settlements so that many people build houses -the house up to the river body. This causes flooding every year and submerges residents homes along the riverbanks. For this reason, an arrangement is needed in the flow of the drainage system on the Ciliwung River and river normalization to be able to avoid disasters that will be caused by flooding. In this study, to cope with disasters that occur in the Kemunig River by planning the construction of dikes at winding points to protect the river slopes from scours. The method of division that will be used is by using the Thiessen polygon method by drawing a line perpendicular to the center line connecting the two stations. The results obtained after direct observation in the field and processing of data related to the Normalization of the Ciliwung River are using the Log Pearson Type III Method.

Chitosan as a feed additive: Its modulatory effect on methane emission and biohydrogenation under artificial rumen system A Jayanegara1,*, R P Harahap2,3, S Suharti1 and Nahrowi1 1 Department of Nutrition and Feed Technology, Faculty of Animal Science, IPB University, Bogor 16680, Indonesia 2 Study Program of Nutrition and Feed Science, Graduate School of IPB University, Bogor 16680, Indonesia 3 Study Program of Animal Science, Faculty of Agriculture, Tanjungpura University, Pontianak 78121, Indonesia Abstract This study aimed to determine the effects of chitosan addition on methane emission, fatty acid biohydrogenation and fermentation profile of rumen simulation technique (rusitec). Four studies reported chitosan use as a feed additive in the rusitec system were integrated into a database. Treatments were categorized into control (no chitosan addition) and chitosan addition at different levels. Various studies were treated as random effects whereas treatments were considered as fixed effects. Data were analyzed by using mixed model methodology. Significance was declared when P<0.05 and tendency was stated when P<0.1. Results showed that chitosan addition reduced methane emission in comparison to control by as much as 28% (P<0.05). Total volatile fatty acid concentration was not altered due to chitosan, but acetate proportion was decreased (P<0.05) while propionate proportion tended to elevate in the addition of chitosan (P<0.1). Chitosan did not influence ruminal pH, ammonia concentration and nutrient digestibility (organic matter, crude protein and neutral detergent fiber) of substrate. Proportions of vaccenic acid (P<0.01) and conjugated linoleic acid (P<0.001) were increased by the addition of chitosan. In conclusion, chitosan may provide beneficial effects in the rumen by mitigating methane emission and elevating fatty acids contributing to human health.
