Siklon Tropis Savannah melewati Daerah Istimewa Yogyakarta pada tanggal 17 Maret 2019. Curah hujan yang disebabkan oleh Siklon Tropis Savannah terekam pada stasiun Geofisika badan meteorologi, klimatologi dan Geofisika (BMKG) Yogyakarta sebesar 170,6 mm/hari dan terekam pada Stasiun Cuaca Beton milik Kelompok Studi Karst Fakultas Geografi Universitas Gadjah Mada sebesar 78,3 mm/hari. Curah hujan menunjukkan bahwa siklon tropis ini menyebabkan terjadinya hujan ekstrim. Siklon Tropis Savannah menyebabkan bencana banjir di beberapa wilayah Daerah Istimewa Yogyakarta salah satunya terjadi di Karst Window Kalinongko, Kawasan Karst Gunungsewu, Kabupaten Gunungkidul. Karst Window Kalinongko terdampak banjir dari meluapnya sungai bawah tanah. Proses terjadinya banjir di Karst Window Kalinongko disebabkan oleh aliran air yang melebihi kapasitas pengaliran dari lorong konduit pada sungai bawah tanah. Sistem konduit yang penuh kemudian meluap ke permukaan dan menggenang pada bagian dolin di sekitar Karst Window Kalinongko. Waktu surut banjir airtanah di Karst Window Kalinongko adalah selama 10 hari. Banjir Siklon Tropis Savannah yang menggenang memiliki volume sebesar 4.894.258 m3, luasan area terdampak seluas 13.723 m2, dan ketinggian genangan 6 meter. Dampak genangan banjir airtanah yang disebabkan Siklon Tropis Savannah di Karst Window Kalinongko merendam lahan sawah seluas 10.586 m2 dan perkebunan seluas 3.137 m2.

The Gunungsewu karst area is not only known for its unique landscape but also its recurring drought events. To meet the water supply, the local population utilizes several water potentials, namely doline pond, spring, and underground river. This study was designed to analyze the hydrogeological conditions of Mbangsri Cave, following its accidental discovery by the community at the end of 2018. The hydrogeological analysis was conducted by geological surveys, which consisted of rocks collection and structural measurements, cave mapping, and recharge area delineation based on remote sensing images acquired by unmanned aerial vehicles. The results showed that Mbangsri Cave, in the hydrogeological perspective, had low water resources potential. It is believed to be the result of (1) relatively small catchment area, (2) a fault in the southern part of Mbangsri Cave, creating a small groundwater basin, and (3) the thin epikarst layer, limiting the water storage.

Tropical Cyclones often occur in Indonesia and have disastrous impacts. Until now, no research has focused on time series data related to groundwater discharge and chemistry due to tropical cyclones. Therefore, this study aims to analyze and compare the characteristics of the hourly time series, both discharge and chemistry of the Guntur karst springs. Guntur Spring was affected by the tropical cyclone of Savannah on March 17, 2019. The method used in this study consisted of two parts, namely the analysis of the discharge and chemistry of Guntur Spring. Discharge analysis was performed by correlation test with rain intensity. Chemical analysis was carried out using the Minister of Health Regulation No. 90 of 2002 and expert standards. Other chemical analyzes were performed using a triangular piper, rectangular piper, and stiff diagram of the parameters Na+, K+, Ca2+, Mg2+, SO42-, Cl-, and HCO3-. The results of the relationship between discharge and rain intensity are directly proportional and increase significantly during a cyclone. The results of analysis of the Guntur Springs during Tropical Cyclone Savannah, all parameters are in accordance with the quality standard. In addition, there was a reduction in ion content due to the dilution process of Ca2+, Mg2+, Cl-, HCO3-., DHL, and pH ions compared to non-cyclone, Beton Resurgence, and Gremeng Resurgence ions. The chemical results when the cyclone is different compared to non-cyclone, Gremeng Resurgence and Beton Resurgence with a characteristic decrease in ionic content.

Mengantuk saat berkendara menjadi ancaman serius yang dapat meningkatkan risiko kecelakaan, yang merupakan penyebab utama kematian di seluruh dunia, termasuk di Indonesia. Deteksi dan pencegahan kondisi mengantuk pada tahap awal menjadi krusial untuk mengurangi potensi kecelakaan dan meningkatkan keselamatan berkendara. Penelitian ini fokus pada pemanfaatan citra wajah pengemudi sebagai metode efektif dalam mendeteksi mengantuk. Rendahnya kontras dalam citra dapat mempengaruhi deteksi wajah, sehingga diperlukan peningkatan kontras citra. Dalam penelitian ini, dua teknik peningkatan kontras citra, yaitu Histogram Equalization (HE) dan Adaptive Histogram Equalization (AHE), dievaluasi. Dataset yang digunakan adalah Driver Drowsiness Dataset, terdiri dari citra Drowsy sebanyak 22,348 dan Non-Drowsy sebanyak 19,445. Pra-pemrosesan melibatkan resize dan pengaburan menggunakan Gaussian Blur, diikuti oleh penerapan HE dan AHE. Evaluasi kinerja dilakukan menggunakan matriks evaluasi, menghasilkan skor Mean Squared Error, Peak Signal-to-Noise Ratio, dan Signal-to-Noise Ratio. Hasil menunjukkan bahwa HE memberikan hasil yang lebih baik dengan skor MSE 101.21, PSNR 28.11, dan SNR 0.19, dibandingkan dengan AHE yang memiliki skor MSE 103.92, PSNR 27.97, dan SNR 0.04. Oleh karena itu, dapat disimpulkan bahwa HE memberikan peningkatan kontras yang lebih baik untuk citra wajah dibandingkan dengan AHE.

This article explains how to determine the tempo of the kendhang, an Indonesian traditional melodic instrument. This research presents novelty as technological research related to gamelan instruments, which has rarely been achieved thus far, through the introduction of kendhang tempo types through the sounds produced, with the hope of creating an automatic system that can recognize the kendhang tempo during a gamelan performance. The testing in this work will categorize the tempo of kendhang into three categories: slow, medium, and fast, utilizing one of the two scenario models proposed, mel frequency cepstral coefficients (MFCC) and convolutional neural network (CNN) in the first scenario, and mel spectrogram and CNN in the second. Kendhang's original audio data, which was captured in real time and later enhanced, makes up the data set. The model 1 scenario, which entails feature extraction using MFCC and classification using the CNN classification approach, is the best scenario in this research, based on the experimental results. When compared to the other suggested modeling scenarios, model 1 has a level of 97%, an average accuracy, and a gain value of 96.67%, making it a solid assistant in terms of kendhang's good tempo recognition accuracy.

Plant Growth Promoting Rhizobacteria, or PGPRs, are a type of bacteria that live in rhizospheres, or the areas of land near tomato plants. These bacteria can cause a variety of processes, such as the formation of nitrogen, the breakdown of fat, the synthesis of phytohormones, and the development of illnesses. The purpose of this nirlaba service is to provide information and resources that are required for pet owners and pertanian owners in order to produce and use PGPR locally and effectively. This is expected to improve tuna quality, increase tuna health, and result in more efficient use of pupuk. The training's outcome indicates that participants can create and use PGPR on their own effectively, increasing textile production on a global scale. This training also emphasizes the importance of environmental sustainability and resiliency through the use of PGPR agents.

Compared to other landforms, karst areas are among those emerging from the dissolution process that have a higher risk of land degradation. The likelihood of karst landforms being harmed is increased by urbanization and other human activities like extensive agriculture. Subsurface streams' water quality gets worse when surface pollutants infiltrate through developed karst features like sinkholes and karst ponors. There is a greater risk of land degradation as more karst features, in this case void size, develop. The purpose of this research is to assess how void development, or the degree of karstification, relates to the potential for karst spring pollution in the event that land degradation occurs on the surface of the Karst Drainage System (KDS). This research was conducted at the KDS of Beton and Gremeng Spring in the Gunungsewu karst area, Indonesia. In addition, this study also provides recommendations related to environmental management on the basis of the level of development of voids at both sites. The degree of karstification represents the phase at which a hydrogeological system has been developing, and this information was later considered in formulating strategies for protecting karst groundwater from contamination. The results show that Beton and Gremeng had a complex discharge regime with degrees of karstification at 8 and 5.5, respectively. Based on flood hydrograph components, it was further confirmed that both areas were in the mature phase. The higher the degree of karstification, the higher the vulnerability to pollution.
