Abstract

Balikpapan City has a moderate level of vulnerability to landslides. This is because the city of Balikpapan has the triggering factors and causes of landslides. The trigger factor is a tropical climate with high rainfall of 2,887 mm/year. While the causative factor is that 85% of the Balikpapan City area consists of hilly areas. Therefore, it is necessary to conduct research monitoring soil conditions. This study uses several sensors such as the MPU6050 sensor, Capacitive Soil Moisture V1.2 sensor, buzzer, and the NodeMcu ESP8266 microcontroller. This prototype acts as an early warning system. The buzzer on the prototype will sound if the landslide hazard condition is identified. In addition, this prototype sends data on soil conditions via the Telegram Messenger Bot on the Telegram Messenger application. The results of data collection when the slope of the soil is 10o to 30o, the condition of the soil does not vibrate, and the soil moisture is dry is that there is no landslide. However, when the slope is 40o to 50o and the soil moisture is dry, the result is a landslide. For the data results when the slope is 10-40o, the soil condition does not vibrate, and the soil moisture is moist, there is no landslide. However, at a slope of 50o and moist soil moisture, landslides occur. For data results with a slope of 10o - 50o, the condition of the soil does not vibrate and the moisture of the wet soil is that there is no landslide. For the data results when water is flowed directly using a water hose at a slope of 10o to 30o and the ground does not vibrate is that there is no landslide. However, at a slope of 40o to 50o, the ground does not vibrate and landslides occur.

Abstract

Telah banyak penelitian tentang pengenalan emosi suara dengan akurasi yang berbeda-beda. Hal tersebut disebabkan oleh dataset, fitur-fitur, dan model klasifikasi yang digunakan. Hal yang paling mempengaruhi tingkat akurasi pengenalan emosi suara adalah fitur-fitur yang digunakan. Sehingga pada penelitian ini dilakukan eksplorasi terhadap kombinasi kombinasi fitur-fitur spektral dan bagaimana pengaruhnya terhadap akurasi dari pengenalan emosi suara. Kombinasi fitur yang digunakan adalah fitur-fitur spektral low level descriptor yaitu mel-frequency cepstral coefficient (mfcc), chroma, mel-spectrogram, spectral contrast, spectral bandwidth, dan tonnetz, dan fitur-fitur high-statistical function (HSF), yaitu mean, standar deviasi, jangkauan interkuartil, skewness, dan kurtosis dari fitur-fitur LLD sebelumnya. Model yang digunakan adalah long short-term memory (LSTM). Hasil yang didapatkan adalah dari keseluruhan percobaan kombinasi fitur LLD dan HSF, fitur mfcc dan spectral contrast memberikan nilai akurasi dan UAR tertinggi. Jika fitur mfcc ini dihilangkan maka nilai akurasi dan UAR akan turun secara signifikan. Selain itu penelitian ini memberikan bukti bahwa semakin banyak fitur yang digunakan tidak selalu memberikan hasil akurasi dan UAR yang baik. Namun yang paling mempengaruhi adalah fitur apa yang digunakan, bukan seberapa banyak fitur yang digunakan.

Abstract

Sistem penyiraman manual di Kebun Melon Sumber Berkah, Balikpapan, dinilai kurang efisien karena memerlukan waktu 9-10 jam per hari, yang menyebabkan beban kerja tinggi bagi petani dan tidak optimalnya hasil produksi. Untuk mengatasi permasalahan ini, dikembangkan sistem penyiraman otomatis menggunakan teknologi irigasi tetes yang diharapkan mampu meningkatkan efisiensi tenaga kerja, mengurangi waktu penyiraman, dan meningkatkan produktivitas panen. Metode pengabdian ini dimulai dengan survei lapangan untuk memahami kondisi lahan serta wawancara dengan pengelola kebun guna mengidentifikasi masalah utama yang dihadapi. Berdasarkan hasil analisis tersebut, dirancang dan diimplementasikan sistem penyiraman otomatis. Tahapan yang dilakukan mencakup pembelian bahan, pemasangan sistem, serta sosialisasi kepada pengelola kebun mengenai cara kerja dan manfaat sistem irigasi tetes. Hasil yang diperoleh menunjukkan peningkatan efisiensi yang signifikan. Waktu yang diperlukan untuk penyiraman berkurang hingga 60%, sehingga petani dapat memanfaatkan waktu yang tersisa untuk aktivitas lain yang lebih produktif. Selain itu, sistem ini juga diperkirakan mampu meningkatkan hasil panen sebesar 20-30%. Berdasarkan hasil angket, terdapat peningkatan kepuasan dari petani terkait penggunaan sistem ini, yang dilihat sebagai solusi efektif untuk permasalahan penyiraman di kebun. Program ini berhasil memberikan kontribusi nyata dalam meningkatkan produktivitas pertanian dan kesejahteraan masyarakat setempat.

Abstract

Based on Law Number 1 of 1970 concerning Occupational Safety is not only applied in industry, but in all workplaces, it is mandatory to apply Safety and Security (K3), one of which is in education both at school and college levels which have a high risk of danger. The cause of work accidents occurs due to Unsafe Action factors reaching 88% and 10% Unsafe Conditions. Health and Safety Executive data states that 90% of accidents are caused by human error. The purpose of the research is to design AC and DC electrical safety training modules that can be used as practicum media for students in understanding the basic principles of electrical risk control and prevention of explosion hazards due to errors in electrical systems. The engineering and development method is the design and fabrication of training modules, which consist of AC and DC electrical devices, equipped with risk control systems such as automatic circuit breakers, grounding systems, and short circuit protection. The results show that the circuit design consists of 2 circuits, namely AC and DC circuits. The circuits can be separated and can be combined by considering making it easier to carry out practicum and maintenance processes to prevent failures in the system that can cause accidents.

Abstract

The pepper drying process is generally carried out conventionally under inefficient sunlight and is dependent on the weather. This study aims to analyze the performance of an automatic sieving system in a greenhouse-based pepper dryer that uses solar panels as an energy source. The main innovation of this study is the implementation of an automatic sieving mechanism to ensure even heat distribution during the drying process. The system is controlled by an Arduino Uno microcontroller with input from DHT22 sensors for temperature and humidity, and a load cell to detect weight loss of the material. A servo motor is used to move the sieve at certain intervals. Tests were conducted under two conditions, namely with and without automatic sieving, using a 60 W incandescent lamp at an average temperature of 55°C. The results showed that the automatic sieving system accelerated the drying time by up to 1 hour and 30 minutes faster than the static system. 100 grams of wet pepper was successfully dried to 75.88 grams in 7 hours, with a water content reduction of approximately 24%. These results indicate that the automatic sieving system effectively increases heat transfer efficiency and accelerates the drying process without additional external electrical energy.
