Abstract

Indonesia is an archipelagic country that has a very wide sea area. Thus, Indonesian sea has a huge potential of natural resources that can be utilized to grow the nation's economy. There are many occupations and efforts that can be done to increase the income from the sea and also to conserve it. Fishery is one of the most effective way to gain the sea resources; however, fishery is limited by the weather condition on the sea. This is also a problem that happened in Puger Beach. Puger Beach is located in the south Jember and it faces the Hindia Ocean, which means the weather condition is more dangerous for fishermen than other part of coastal. To ensure the safety of the fishermen, the weather condition on the sea must be evaluated and predicted before the fishery. This study designed a system to provide fishermen in Puger Beach an information about sea and beach weather condition which consist of wave height prediction, wind speed, temperature, humidity and weather prediction. The wind speed is obtained from self-designed anemometer system, the temperature is measured using LM35 sensor, and the humidity is assessed using DHT22. The wave height in the sea was predicted by calculating the wind speed value and effective average fetch value using neural network algorithm. The weather on the sea and on the beach were predicted by rain and light sensor. This weather prediction would be classified into three different results, namely raining, cloudy and bright. After some experiments, the result showed that the device can provide the information needed for fishermen and it has a high sensing accuracy. The humidity measurement had an average error of 1.1%, the temperature measurement had 1.42% average error, and 2.37% for the wind speed measurement. The wave height measurement system worked out and found the average wave height in Puger Beach 0.37 meters.

Abstract

The use of the preloading method, which combined with PVD, is now a common method of soil improvement that proved effective in increasing bearing capacity and reducing settlement on soft soil ground types like former rice fields. In order to reach an optimum effectiveness of soil improvement, an evaluation of the settlement should be done by reviewing the performance of soil improvement along with geotechnical instruments installed in the field. In this study, the back analysis method is used to determine the soil design parameters that are following the actual conditions in the field. The results obtained from the evaluation of settlement conducted is the difference between settlement calculation theoretically before the improvement of soil with the available field data of monitoring Settlement Plate. An average percentage of 118% was obtained from the calculation. In contrast, an average percentage of 2.87% was obtained as the difference between the final settlement prediction of Asaoka's with actual settlements based on Settlement Plate readings data in the field. The parameters of the soil results from the back analysis gave new values with each of the average of Ch= 0.02936; Cc= 0.27313; kv= 0.00005 m/day; and mv= 0.00064m2/kN. The difference between theoretical settlement recalculated using the soil parameter of the back analysis method with the actual settlement based on monitoring of Settlement Plate gave an average percentage of 12.66%. Metode Preloading yang dikombinasikan dengan PVD merupakan salah satu metode perbaikan tanah yang terbukti efektif dalam meningkatkan daya dukung tanah dan mengurangi settlement pada tanah jenis lunak seperti tanah bekas sawah. Agar perbaikan tanah yang dilakukan memiliki efektifitas optimum, perlu adanya evaluasi terhadap settlement yang terjadi dengan meninjau kinerja perbaikan tanah beserta instrumeninstrumen geoteknik yang terpasang di lapangan. Selain itu, dilakukan Metode Analisa Balik untuk mengetahui parameter desain tanah yang sesuai dengan keadaan sesungguhnya di lapangan. Hasil yang didapatkan dari evaluasi settlement yang dilakukan adalah selisih settlement secara teoritis sebelum adanya perbaikan tanah dengan settlement berdasarkan monitoring Settlement Plate di lapangan dalam persentase rata-rata sebesar 118%, sedangkan selisih antara final settlement prediksi Asaoka dengan settlement akhir berdasarkan monitoring Settlement Plate di lapangan mendapatkan persentase rata-rata sebesar 2,15%. Parameter-parameter tanah hasil dari analisa balik memiliki nilai baru dengan masing-masing rata-rata sebesar Ch= 0,02936; Cc= 0,27313; kv= 0,00005 m/hari; dan mv= 0,00064m2 /kN. Sedangkan untuk selisih antara settlement secara teoritis yang dihitung kembali menggunakan parameter tanah hasil analisa balik dengan settlement aktual berdasarkan data bacaan Settlement Plate mendapatkan persentase rata-rata sebesar 12,66%.

Abstract

Early warning of floods is an essential part of disaster management. Various automatic detectors have been developed in flood mitigation, including cameras. But reliability and accuracy have not been improved. Besides, the use of monitoring devices has been employed to monitor water levels in various water building facilities. The early warning flood detector was carried out with a sensor camera using an orange ball that floats near the water level gauge in a bounding box. This approach uses the integration of computer vision and image processing, namely digital image processing techniques, with Sobel Canny edge detection (SCED) algorithms to detect quickly and accurately water levels in real-time. After the water level is measured, a flood detection process is carried out based on the specified water level. According to the results of experiments in the laboratory, it has been shown that the proposed approach can detect objects accurately and fast in real-time. Besides, from the water level detection experiment, good results were obtained. Therefore, the object detection system and water level can be used as an efficient and accurate early detection system for flood disasters.

Abstract

Meru Betiri National Park (TNMB) is a natural conservation area related to land use that impact on the environment. Land-use suitability with land capability is essential so that the impact of the geological environment that can occur can be reduced and controlled. The research aims to determine the aspects of environmental geology and zoning land capability for governance of TNMB. Geological aspects of the environmental order that support this research are morphology (slope), lithology, hydrogeology (river density), and land cover. Each aspect is a parameter in the Analytical Hierarchy Process (AHP) evaluation method. The weight of each parameter of the AHP evaluation result is 26% for slope, 19% for lithology, 11% for river density, and 44% for land cover. The result of overlay parameters yields a score of each zoning and is classified into 4 (four) zoning land capabilities for governance of TNMB. The land use zone for governance of TNMB is divided into high capability zones, medium capability, low capability, and very low capability. High and medium capability zones can be used as conservation of TNMB primary forests.

Abstract

Indeks vegetasi merupakan parameter yang diperoleh dari citra satelit untuk menggambarkan aspek kerapatan vegetasi di suatu daerah. Kawasan Jember bagian selatan berada di daerah dengan kerapatan vegetasi lebat dan masuk dalam formasi vulkanik yang menjadi indikasi keterdapatan mineral alterasi. Alterasi mineral terbentuk dari proses ubahan pada mineral akibat adanya proses kompleks yang meliputi perubahan secara mineralogi, kimia, dan tekstur pada batuan. Tujuan penelitian yaitu untuk mengidentifikasi keterkaitan perubahan indeks vegetasi dengan keberadaan mineral alterasi. Untuk menghindari kesalahan pengamatan karena kawasan bervegetasi lebat, maka citra Sentinel-2A yang digunakan lebih dari satu waktu (multitemporal). Proses pengolahan data meliputi koreksi geometrik dan atmosferik, perhitungan NDVI (Normalized Difference Vegetation Index), dan observasi lapangan. Rata-rata nilai indeks vegetasi pada April 2021, Juni 2022, dan Juli 2022 masing-masing sebesar 0,5749, 0,6722, dan 0,6316. Persentase tutupan lahan dari tiga series data didominasi oleh kerapatan vegetasi tinggi sampai sangat tinggi dengan nilai di atas 70%. Jenis penggunaan lahan pada kerapatan vegetasi yang tinggi yaitu hutan, perkebunan, sebagian taman nasional, dan lahan pertanian. Mineral yang teridentifikasi antara lain kuarsa, kaolin, piroksen, plagioklas, dan lain-lain. Mineral alterasi argilik ditemukan di kawasan dengan kerapatan vegetasi yang sangat tinggi.
