Abstract

Indonesia merupakan negara yang kaya akan sumber daya alam, budaya, dan pariwisata. Salah satu warisan budaya kemanusiaan yang terkenal di Indonesia adalah Batik Indonesia. Batik adalah kain bergambar yang pembuatannya secara khusus dengan menuliskan atau menerakan malam pada kain itu, kemudian pengolahannya diproses dengan cara tertentu yang memiliki kekhasan. Batik merupakan kerajinan yang memiliki nilai seni tinggi dan telah menjadi bagian dari budaya Indonesia (khususnya Jawa) sejak lama.Penelitian ini bertujuan untuk mengklasifikasikan motif citra batik Yogyakarta (dalam penelitian ini menggunakan motif batik Parang Kusumo dan motif batik Kawung). Metode yang diusulkan dalam penelitian ini adalah ekstraksi fitur GLCM (Grey Level Co-Occurrence Matrix) menggunakan 6 fitur dan klasifikasi menggunakan metode ANFIS (Adaptive Neuro Fuzzy Inference System).Struktur ANFIS yang dibentuk mempunyai  parameter 6 input dari fitur tekstur (GLCM), setiap fitur menggunakan 2 membership function dengan 64 aturan yang berlogika AND. Dengan menggunakan 100 data citra uji, Trapezoidal Shaped-Membership Function memperoleh akurasi terbaik yakni 80%, sedangkan Gaussian Shaped-Membership Function memperoleh akurasi terendah yakni 77%.

Abstract

In this research has been developed a system to conrol robot which have four wheel as a base for wheeled robot contest. The type of wheel is omni-wheel, they are shapeed with same distance each other. This system comonly have no stright movement and have no consistent aim-face of the robot in open loop control. The control system in this research use PID method to control the speed of each wheel. It use to make robot can move strightly and consistent of aim-face of the robot. The test on this system show that rotation speed of each wheel are equal to set point which set to PID control. With tune the paramater of PID with manual tuning method the system get 2.81% motor speed error. And get 0.66% error of aim-face of robot from forward and backward movement.

Abstract

Radio Direction Finder (RDF) had been used as a part of the system in order to  determine the direction of the Radio Frequency (RF) source. This research had used  three different RDF stations without any mobile human operator. The direction data were collected from the each RDF station, it would be calculated using the triangle-centroid-algorithm. Therefore, the RF source position had been automatically determined. This experiment result of the RF source imaginary was compared with the real RF source at about 3.2 meters for latitude, and 3.3 meters for longitude. The results of this method and experiment are very useful for scientist and engineers in application of RF engineering.

Abstract

In recent years, domestic carbage become a serious problem since not all waste is managed properly. The organic waste has a potential as a feedstock for biogas production. Before the fermentation process of biogas production, it is necessary to enumerate organic waste with the help of a multi-function chopper. In the present work, dual function machine (chopping and milling process) is designed and fabricated. The machine is driven with a 5.5 HP gasoline engine with a two-way transmission system connecting to each process. The first line transmission system on the chopping with a pulley size of 2 inch diameter, two grooves mounted on the motor and a 3 inch pulley mounted on the chopper axis with a rotation speed of 2400 rpm. The second line transmission system on the milling uses a 12 inch diameter pulley with a rotation of 600 rpm. The test results show that the capacity of the machine was 60 kg/h with 1 cm chopping size.

Abstract

The presence of quartz sandstone outcrops in the southeast of the study site suggests the presence of quartz sandstones in the northwest, according to the strike direction. This geoelectrical measurement aims to determine the distribution of these sandstones below the surface. The method used is geoelectric with a dipole dipole configuration. Measurements were made on four track lines. Tracks A and B indicate the existence of a layer of sandstone below the surface. Tracks C and D do not show any layers of quartz sandstone. This is caused by the presence of faults or folds that cause the layer to shift from the previously predicted path.

Abstract

Currently, the development of communication technology is very advanced with the presence of cellular and internet technology. However, when there is a public security disturbance and in an emergency situation, cellular communication devices are very dependent on electricity sources and pulses to communicate. Besides, if a natural disaster occurs, the power source will go out and the cellular provider BTS will not function. Radio communication can be used as an adequate alternative technology in dealing with emergencies. Radio communication can be established using simple equipment such as HT (Hand Transceiver), transmitting antennas and repeater stations to extend the communication range. The advantages of radio communication are that it is easier to implement, economical, and has a wide coverage. Therefore, the purpose of this community service activity is to improve skills in using emergency communication tools and provide an understanding of Standard Operating Procedures on how to communicate in an emergency situation. The target of this activity includes members of the National Disaster Relief Agency (BPBD) at Yogyakarta City. There are 2 activities, namely radio frequency regulation and skills workshops using emergency communication tools (HT). The result of this community service activity is that the participants are skilled in communicating using HT in times of emergency.

Abstract

Krambilsawit Village is one of the villages in Saptosari District, Gunung Kidul, categorized as extremely poor despite its tourism potential. Additionally, issues with accessibility, water resources, and electricity render Kambilsawit Village disadvantaged. The aim of this community service is to enhance the capacity of human resources in Kambilsawit Village while implementing appropriate technology to develop local tourism potential. The service took place at the Bedalo Hamlet Hall on Sunday, November 5, 2023, with 15 members of the Pokdarwis Karya Samudra participating in the training. Implementation methods included socialization, training, and counseling on tourism management and awareness, as well as assistance in implementing appropriate technology (TTG). Participants demonstrated high enthusiasm, stating that the activity was highly beneficial and helped broaden their perspectives. The TTG application, comprising a gazebo constructed from natural materials, solar panels, quisdisc, and social media for local tourism development, addressed local issues such as electricity availability, tourism management, and visitor influx, achieving a 100% success rate.

Abstract

Robot bergerak membutuhkan navigasi dalam melakukan gerakan pada arah tertentu. Sehingga koordinasi antara piranti masukan-masukan berupa sensor posisi relatif terhadap titik acuan navigasi yang sudah dipetakan dengan piranti penggerak berupa motor. Koordinasi antara masukan dengan keluaran dijembatani oleh piranti pengendali. Piranti pengendali berfungsi sebagai otak sistem yang mampu membandingkan dan memberikan keputusan terhadap masukan menjadi sebuah keluaran berupa pergerakan robot berdasarkan pengetahuan yang ditanamkan maupun hasil pembelajaran dari kesalahan yang pernah terjadi. Dalam sistem robot tersusun tiga bagian sistem, yaitu perangkat mekanis, perangkat elektris dan perangkat lunak. Pada masing-masing bagian tersebut berpotensi untuk menimbulkan karakter-karakter baru baik disadari kemungkinan munculnya maupun yang tidak disadari kemungkinan munculnya.

Abstract

Every life is never separated from the need for water because water is a basic need, especially for humans, both for drinking, bathing, and at the time of pilgrimages to tombstones they the visit. Meanwhile, to get the water, the community lifts it from the nearest water source, namely a healthy water source, which is done manually by drawing water and putting it into a water reservoir. Suppose done enough draining continuously. In addition, to get a power source at the burial site, the community takes electricity from the nearest power source or residents' homes. However, this can be overcome by using an alternative solar power generation system as a driving force for a water pump to lift DC water designed portable to meet water needs. By doing a design using two solar panels of 100watt peak, a solar charge controller with a capacity of 20 amperes and a battery unit with a total of 20Ah able to lift water from the well to a water reservoir 89.034 liters in 8 minutes. The electrical energy required for single use of the water pump is 23.4 Wh, so it is expected to increase the use of time, energy, and the volume of clean water to be more efficient.
