Abstract

Mamuju Regency is the capital city of West Sulawesi Province and is one of the districts that are prone to flooding. This study aims to analyze flood-prone locations based on the physical condition of Mamuju Regency which includes rainfall, slope, elevation, soil type, river buffer and land use. The results showed that there is an area of 279.84k㎡ in Mamuju Regency which has a high vulnerability to flooding. Areas that have a high level of flood vulnerability are mostly located in the western part of Mamuju Regency because the land cover is dominated by settlements and ponds and has a relatively flat topography. Meanwhile, areas with moderate and low levels of flood vulnerability are 1695.47k㎡ and 2959.33k㎡, respectively.

Abstract

The springs in Grabag Sub-district have decreased the quantity of water because of a large amount of water taken from the springs by the residents and PDAM. This can threaten the volume of existing springs. This study aims to analyze the quantity vulnerability of the spring area and identify the conservation in the management of springs in the study area by using a Geographic Information System (GIS) application. The data used is the observation of data in the field and laboratory. Data as soil type, morphometry, constituent lithology, land use, vegetation, water discharge, access, and use of water. We classify the vulnerability of springs in the study area as low - medium vulnerability. Areas of low vulnerability, vulnerability class 2.0–2.6 are scattered in the springs of Tuk Ngrancah, Tuk Tlogosari, Tuk Gedad, and Tuk Tlogorejo. This area is composed of colluvial deposits of regosol soil, low rainfall (1750–2250 mm/year), sloping slopes (9-15°), and they used the land as gardens. Medium classification areas, with vulnerability class 2.7–3.3 spread over the springs of Tuk Bleder, Tuk Mas Kalimas, Tuk Kembar, and Tuk Udal. This area is composed of colluvial deposits of latosol soil, moderate rainfall (2250-2750 mm/year), undulating slopes (16-25°), and land use as gardens. The direction of spring conservation techniques is as agronomic conservation techniques with vegetative methods. The application of this method to springs with low vulnerability classification is the use of bamboo (Bambusa sp.) as a ground cover plant. Coffee liberika (Coffea liberika) together with lamtoro (Leucaena leucochephala) and sugar palm (Arenga pinnata) were directed to springs with moderate susceptibility classification. The existence of agro-tourism land through coffee cultivation is the direction of agronomic conservation techniques in Grabag District.

Abstract

Proses erosi pantai atau abrasi semakin hari semakin memprihatinkan perlu adanya keberlangsungan proses sedimentasi pantai untuk mengurangi abrasi pantai. Salah satunya adanya tanaman mangrove untuk mengurangi abrasi pantai. Mangrove merupakan ekosistem yang tumbuh di atas rawa-rawa berair payau yang terletak pada garis pantai atau muara sungai yang dipengaruhi oleh pasang-surut air laut yang terlindung dengan sedimen berlumpur hingga berpasir. Maka perlunya adanya penelitian untuk mmengetahui kondisi fisik sedimen terkait hubungannya dengan struktur tubuh mangrove. Penelitian dilakukan didaerah Dusun Baros, Desa Tirtohargo, Kapanewon Kretek, Kabupaten Bantul, Daerah Istimewa Yogyakarta, yang memiliki morfologi berupa daerah pasang surut muara Sungai Opak. Tujuan dari penelitian ini adalah untuk mengetahui kondisi komposisi fisik sedimen pada muara Sungai Opak pada struktur sederhana tubuh vegetasi mangrove. Metode yang dilakukan pengambilan data sedimen dan pengamatan tubuh vegetasi mangrove. Dilakukan pada 3 lokasi. Pengambilan data sedimen dilakukan dengan cara mendapatkan komposisi fisik sedimen berupa ukuran butir serta parameter statistik (mean, sorting, skewness dan kurtosis) parameter ini digunakan untuk mengetahui proses sedimentasi yang berlangsung terkait dengan lingkungan sedimentasi. Pada tumbuhan mangrove dilakukan pengamatan tutupan kanopi (daun batang mangrove), struktur sederhana tubuh mangrove dan jenis mangrove. Tutupan kanopi dilakukan dengan metode Hemispherical Photography dari data ini didapatkan baik buruknya tutupan kanopi dalam persentase. Struktur sederhana dilakukan pengamatan anatomi tubuh tumbuhan mangrove seperti batang lurus atau bercabang akar tanaman. Hasil analisis menunjukkan bahwa sampel yang lebih dekat dengan muara sungai memiliki ukuran butir lebih besar dibandingkan dengan sampel yang lebih jauh dari sungai dan terdapat genangan air. Berdasarkan tutupan kanopinya, semua jenis mangrove dapat tumbuh dengan baik dan cocok dengan kondisi jenis sedimennya. Hasil pengelompokan dominasi jenis mangrove didapatkan bahwa jenis Avicennia sp dapat ditemukan di seluruh stasiun pengamatan sehingga dapat dikatakan mangrove jenis ini dapat beradaptasi dengan kondisi sedimen yang berukuran pasir sedang hingga lebih halus, sedangkan mangrove jenis Rhizopora sp hanya dijumpai pada stasiun pengamatan yang berada lebih jauh dari muara sungai dengan jenis sedimen yang lebih halus. Proses sedimen menyebabkan adanya endapan yang menjadi pengurangan abrasi pantai. Kata Kunci: Sedimen, Mangrove, Granulometri, Kanopi Mangrove

Abstract

The availability of medical record data can affect the health services that will be provided, starting from treatment planning, therapy, and health facilities provided to patients. The integrity of electronic medical record data needs to be maintained, a method that can be used by implementing a decentralized database system, namely implementing blockchain technology. In addition to data integrity, data standardization also needs to be carried out in the health area, in order to facilitate the integration process with other systems. The international data standard that can be used is FHIR (Fast Healthcare Interoperability Resources). FHIR has great potential to be developed in Indonesia because several hospitals in Indonesia already have a health system and electronic medical record data. BigchainDB and FHIR can be combined to store electronic medical record data, the results of this study by implementing both, the BigchainDB database system requires a long processing time, when compared to MongoDB and MySQL, but for reading medical record data it is not much different from MongoDB. The most effective and efficient MongoDB database for storing and reading medical record data is the FHIR scheme, but this database needs to be configured more deeply in order to get decentralized features like BigchainDB. MySQL has faster data storage capabilities when compared to BigchainDB, but for data reading and the need for a replication scheme to get features such as decentralization, a more in-depth configuration is needed.
