Abstract

Earthquakes are one of the most common disasters in Indonesia. Earthquakes occur when the earth vibrates or shakes releasing the elastic strain energy of rocks by the activity of shifting earth plates. Earthquakes have various adverse effects, namely damage or destruction, and even casualties. In an effort to increase awareness and minimize victims of earthquakes, a tool is needed to provide warnings and detect the occurrence of an earthquake. In this study, a prototype was made to detect earthquakes by utilizing WhatsApp message notifications. This prototype uses several modules such as, arduino nano, ESP8266, SW 420 vibration sensor, ADXL335 Accelerometer Sensor, Buzzer and LED. The ADXL335 accelerometer sensor detects vibration and acceleration direction and the SW 420 vibration sensor detects a vibration which then the data will be received and processed by Arduino UNO and the results of the data calculation will be forwarded to ESP8266 which will later be sent via WhatsApp. When a vibration or earthquake occurs, the buzzer will sound and the LED will light up. The serial monitor display will show the direction of the earthquake and the magnitude of the earthquake. The result of this research is a prototype of earthquake early warning and detection with the concept of IoT (Internet of Thing). This tool or system will be a conceptual prototype. The making of this tool or system is an effort to anticipate victims of earthquakes and as a way to prevent earthquakes.

Abstract

Seagrass potential has been explored recently, including the bioactives contained therein. It is known that seagrass has antibacterial, antioxidant, and antifouling activities. The ability of seagrass as antifouling needs to be further developed. The activity of fouling organisms is a problem, especially in the fisheries and shipping sectors. This study aimed to analyze the anti-macrofouling power and identify bioactive compound groups of seagrass Enhalus acoroides methanol extract from Morotai Island Waters. Seagrass samples were obtained from Tanjung Saleh Village, North Morotai District, Morotai Island. Seagrass extraction was carried out using a maceration method and a methanol solvent. The antifouling activity test was conducted using a wood block. Identification of bioactive compounds was carried out qualitatively using a chemical detector. The extraction results showed that the highest yields were leaves, as much as 9.81%, and rhizomes, as much as 6.28%. The identification of bioactive compounds showed that the methanol extract of E. acoroides leaves (EMDEa) contained alkaloid, saponin, and phenol compounds. In contrast, the methanol extract of E. acoroides rhizomes (EMREa) contained saponin and quinone compounds. The results of the anti macrofouling activity test showed that EMDEa has antifouling activity with the discovery of a small quantity of attachment of fouling organisms (46.00%) on wooden blocks, painting treatment with wood paint showed the percentage of fouling organism coverage of 98.33%, painting with varnish of 97.67%, and without painting showed the percentage of fouling organism coverage of 100%.

Abstract

Penelitian ini mengevaluasi akurasi data curah hujan satelit GPM IMERG sebelum dan setelah kalibrasi di DAS Kuranji. Tujuannya adalah untuk menentukan ketepatan data satelit dalam merepresentasikan kondisi curah hujan aktual dan mencari metode untuk meningkatkan akurasinya. Hasil validasi menunjukkan bahwa data GPM IMERG dalam kondisi mentah memiliki korelasi yang moderat dengan data pengamatan di lapangan, namun nilai RMSE yang tinggi dan NSE yang negatif mengindikasikan akurasi yang rendah. Setelah dilakukan kalibrasi menggunakan analisis regresi, korelasi antara data satelit dan data pengamatan meningkat secara signifikan. Meskipun demikian, nilai NSE masih belum optimal, menunjukkan bahwa model satelit belum sepenuhnya mampu mereproduksi pola variabilitas curah hujan. Hasil penelitian ini menunjukkan bahwa data GPM IMERG memiliki potensi yang besar dalam analisis hidrologi, namun memerlukan proses kalibrasi yang cermat untuk meningkatkan akurasinya. Penelitian ini memberikan kontribusi penting dalam pengembangan metode pemanfaatan data satelit untuk mendukung berbagai aplikasi hidrologi, terutama di daerah dengan keterbatasan data pengamatan.

Abstract

Waste management has become a crucial issue due to the lack of adequate tools, with workplace accidents continuously rising in this industry. According to data from the ILO, there were 2.78 million deaths due to work-related accidents and diseases in 2017, an increase from 2.33 million in 2011. In the waste management sector, workers face injury risks such as fractures, eye damage, and spinal problems, with potential hazards arising from landfill collapses, fires, and getting caught in processing machines. This research aims to design an automated poka yoke system for waste shredding machines to enhance occupational health and safety (OHS) at TPS3R (3R Waste Management Facility). The methods used include the design and testing of a sensor-based automation system to prevent work errors. This system employs photoelectric proximity sensors and inductive proximity sensors to detect hands and metals entering the machine. Testing shows that the photoelectric sensor detects objects at distances of 5-25 cm in the organic and inorganic shredding area with a success rate of 100%, while the inductive sensor successfully detects metals such as screwdrivers, iron plates, and cans. The results of this study indicate that the implementation of an automated poka yoke system can minimize the risks of workplace accidents and machine damage due to human error. Additionally, this system is effective in enhancing operational safety.

Abstract

The long time it takes for concrete to harden is a disadvantage of this material compared to other materials. Concrete is a material that is often used in infrastructure development. There are alternative construction materials where concrete can flow through the reinforcement and fill the entire space in the mould densely without any compaction assistance, namely SCC concrete. The purpose of this research, the manufacture of SCC concrete utilises industrial waste as a filler for cement replacement materials, namely Fly ash and Silica fume. By using American Concrete Instituted (ACI) mix planning and EFNARC standards, making 3 cylinders of concrete measuring 30 cm x 15 cm and with the design of adding fly ash (2%), silica fume (9%) in the Civil Engineering Laboratory of Universitas Muhammadiyah Surakarta, this addition can produce a compressive strength of 24 Mpa within 1 day exceeding the required compressive strength and can reduce the percentage of impact on the environment compared to conventional concrete by; cement (50.96%), fly ash (100%), silica fume (100%). The results of this research can reduce social impacts such as, helping in urgent construction such as roads, reducing noise effects, and of course also reducing project costs. The expenditure for making SCC concrete with fly ash and silica fume is quite economical at Rp. 1,624,517.25/m³. This research is expected to be a sustainable, easy, fast, efficient and economical concrete innovation but also high quality.

Abstract

Road infrastructure plays an important role in connectivity, mobility, and economic growth. In Indonesia, road damage is often caused by heavy loads, heavy traffic, and environmental changes. This study aims to improve the quality of asphalt by mixing Asphalt Concrete Wearing Course (AC-WC) with Fly Ash and Rubber Waste. Fly Ash, with a silica content of 46.7% and Rubber Waste, which has a high viscosity at a temperature of 60°C, are used as substitutes for stone ash and sand.The study was conducted at the Engineering Laboratory of Sultan Agung Islamic University, Semarang using a mixture of Fly Ash at a percentage of 0%, 2%, 4% and 6%, and Rubber Waste 0%, 1%, 2%, and 3% of the weight of the test specimen. After making 48 test specimens, Marshall testing was carried out using the Marshall Compression Machine.The results showed that the addition of Fly Ash and Rubber Waste affected the stability of the asphalt, with the Marshall Quotient value decreasing compared to the normal mixture. The decrease was caused by the large number of cavities in the test specimens. The Marshall stability optimization value for the variation of Fly Ash 6%, Rubber Waste 1% is 814.81 kg/mm ​​and for the variation of Fly Ash 6%, Rubber Waste 2% is 804.99 kg/mm.
