Abstract

Vegetation analysis on the upper Mahakam river border. The Mahakam River Basin (DAS) is very wide, reaching 7.724.300 Ha. The condition of the vegetation in the Mahakam watershed continues to change due to the development of plantations, mining, and settlements. On the other hand, efforts to maintain biological resources from the diversity of vegetation are needed to protect against extinction. Remote sensing data can be used to differentiate between primary and secondary vegetation economically. However, it has limitations for detecting vegetation composition and the number of individuals per unit area. Therefore, field surveys in the context of conducting vegetation analysis are still needed to complement remote sensing data. This study aims to analyze the vegetation in each growth phase, namely the seedling, sapling, pole, and tree phases on the Mahakam riverbank. The method used is to make observation plots of 13 plots for each growth phase. Plots of 2 x 2 m2 for seedling observation, 5 x 5 m2 for sapling level, 10 x 10 m2 for pole level, and 20 x 20 m2 for tree level observation. Based on data analysis, the seedling stage consisted of 30 species, the average number of stems was 25576.9 per ha, the species diversity index was 1.371, and the highest important value index was 21.8% of Coffea robusta. There were 17 species of saplings, an average number of 4,092.3 stems per hectare, a diversity index of 1,118, and the highest important value index of 39.5% from Theobroma cacao. The pole level contained 16 species, the average number of stems was 1023.1 per hectare, the diversity index was 1.138, and the highest interest index was 23.7% for Paraserianthes falcataria. The tree level consists of 30 species. The average number of stems is 255.8 per hectare, the diversity index is 1.282, and the highest important value index is 54.9% of Durio zibethinus. From the results of the study, it can be concluded that most of the vegetation in the Mahakam riverbank area is former fields or agricultural activities.

Abstract

Related to poverty, an important issue that needs attention is the relatively large number of poor people. This relatively large number of poor people is mainly associated with poverty alleviation efforts, both through funding by the central government and local governments. However, such a high-quantity effort has not been able to significantly alleviate poverty. This can be seen from the worsening quality of the poor. So to get these results, a geographical information system (GIS) is needed or commonly known as a geographic information system (GIS) so that data on poor households is right on target. A geographic Information System is a tool that can be used to assist in analyzing the condition of an area in the field of the population to determine the level of welfare of its population. GIS can also convey information in the form of thematic maps so that the condition of an area towards poverty can be presented in the form of visualization of thematic maps and can make it easier for users to understand the information conveyed. The expected result is that this GIS application can make it easier to provide information to the public about the existence of poor households in the Palaran District.

Abstract

This research is motivated by the low level of dissemination of tourism information in the city of Samarinda. Samarinda is one of the cities with very diverse and interesting tourism potentials to explore. The beauty of the urban area and being one of the cities that is crossed by the largest river in the province of East Kalimantan, namely the Mahakam river, makes it one of the tourist destinations that has its own charm, but unfortunately at this time the tourism places in the city of Samarinda have not been widely publicized due to lack of information. About tourism that is given to the public and there are also some places that have not been or have just been opened to become tourist sites. This study uses spatial data in the form of location coordinates and non-spatial data in the form of attribute data including tourist names, addresses, and types of tours, descriptions and pictures. Making the Samarinda City Tourism Geographic Information System website using the Leaflet API as a base map. The database created using PHPMyAdmin on the Samarinda City Tourism Geographic Information System is based on collecting secondary data on tourism information at the Samarinda City Tourism Office and also collecting primary data by interviewing tourist objects that have not been recorded at the Samarinda City Tourism Office. The system and appearance of the Samarinda City Tourism Geographic Information System website was built with the CodeIgniter 3 framework using Visual Studio Code as a text editor. The results of this study are the Samarinda City Tourism Geographic Information System which provides information on tourist names, addresses, types of tours, location coordinates, descriptions, images and is equipped with search features and also road routes to tourist sites. It is hoped that the Samarinda City Tourism Geographic Information System can provide adequate information about tourism information in the city of Samarinda so as to facilitate the delivery and acceptance to the public, especially prospective tourists.

Abstract

The development of Geographic Information System (GIS) technology has provided significant benefits in various fields, including the monitoring of crime-prone areas. GIS is used to minimize the traces of these crimes. This study aims to map crime-prone areas in the Samarinda Seberang and Loa Janan Ilir Districts to identify which areas are potentially vulnerable, allowing for analysis for prevention and handling. The data used were collected from theft cases that occurred in these districts in 2019 and 2020. The research employs a scoring technique where each parameter is rated according to its classification. The results of the scoring process are then analyzed to determine the level of crime-prone areas, categorizing them as very vulnerable, vulnerable, or not vulnerable. Based on respondents' feedback, the application facilitates users in locating crime-prone areas, with 94.34% of responses indicating agreement or strong agreement. These results suggest that the application is feasible for implementation.

Abstract

Tujuan penelitian ini adalah untuk mengidentifikasi sub-sistem dan variabel dalam pemanfaatan sumberdaya air terkait sektor ekowisata di Kampung Merabu serta menganalisis pola pemanfaatan air yang berkelanjutan dengan berbagai skenario pengembangan ekowisata. Kampung ini terletak di Kecamatan Kelay, Kabupaten Berau, Kalimantan Timur. Metode yang dilakukan adalah dengan pendekatan model sistem dinamik. Untuk dapat membangun model sistem dinamik, digunakan perangkat lunak yaitu Vensim. Ada tiga sub-sistem utama yaitu: 1) air limbah domestik kegiatan selain jamban, 2) air limbah domesti kegiatan jamban, 3) pemakaian air. Ketiga sub-sistem tersebut dihubungkan dengan dua badan air yang berada di kawasan Kampung Merabu yaitu sungai Lesan dan Danau Nyadeng, yang kemudian dihubungkan dengan variabel penduduk dan wisatawan. Kedua badan air ini memiliki peran pemanfaatan yang berbeda. Sungai Lesan adalah tempat berakhirnya air limbah domestik, sedang Danau Nyadeng adalah sumber air bersih penduduk. Ada empat skenario yang disimulasikan, yaitu satu baseline dan tiga lainnya berbasis pertumbuhan wisata (dengan periode 25 tahun). Hasilnya skenario pertumbuhan wisata tidak dapat dijadikan sebagai dasar strategi pengembangan ekowisata Merabu, karena beban pencemar air limbah domestik eksisting telah melampaui daya dukung lingkungan. Perlu diupayakan adanya sistem pengelolaan air limbah domestik setempat, sebagai bagian dari strategi pengembangan sektor ekowisata di kampung Merabu.

Abstract

Pertumbuhan penduduk Kalimantan Timur yang sangat cepat dan juga pelaksanaan kegiatan pertanian di Kalimantan Timur yang relatif rendah menimbulkan permasalahan dalam pemenuhan kebutuhan pangan masyarakat di Kalimantan Timur. Dalam usaha meningkatkan pelaksanaan kegiatan pertanian di Kalimantan Timur, perlu dilakukan pertanian skala mikro, yaitu dengan melakukan pertanian hidroponik dengan memanfaatkan lahan kosong di atas gedung (rooftop). Untuk meningkatkan keberhasilan dalam pertanian mikro tersebut, perlu memperhatikan lama penyinaran matahari pada lokasi pertanian tersebut. Dengan berkembangnya teknologi GIS dan Remote Sensing, hal ini dapat memungkinkan untuk dilakukan kajian penentuan lokasi yang optimal untuk pertanian pintar (smart farming) hidroponik, khususnya pada parameter lama penyinaran matahari di lingkungan Politeknik Pertanian Negeri Samarinda. Salah satu data spasial yang dapat digunakan dalam kajian ini adalah data Digital Elevation Model (DEM) dari pesawat nirawak (Unmanned Aerial Vehicle/UAV). Berbagai metode analisis spasial dapat diterapkan untuk dapat mengekstraksi nilai lama penyinaran matahari pada suatu lokasi, salah satunya adalah penentuan area bayangan sinar matahari (Hillshade) dan teknik penjumlahan dengan pembobotan (Weighted Sum). Hasil Dari penelitian ini didapatkan bahwa ada 3 Gedung yang memiliki kriteria cocok sebagai rencana lokasi hidroponik, yaitu antara lain: a) Gedung I, dengan luas 172.5 m2 dan lama penyinaran maksimal 12 jam/hari; b) antara GedungG dan H, dengan luas 130 m2 dan lama penyinaran maksimal 12 jam/hari; serta Gedung E, dengan luas 737,49 m2 dan lama penyinaran maksimal 12 jam/hari. Dari hasil kajian dimana didapatkan area yang sesuai dan memiliki lama penyinaran matahari yang optimal di lingkungan Politeknik Pertanian Negeri Samarinda, memberikan gambaran bagi pelaku pertanian, baik dosen maupun mahasiswa, dapat mengembangkan pertanian pintar hidroponik pada lokasi rooftop tersebut. Selain itu penelitian ini dapat tingkatkan lebih lanjut untuk mengkaji lokasi yang optimal untuk produksi daya mandiri (Panel Surya) sebagai supply daya pada kebutuhan pertanian pintar hidroponik selanjutnya.

Abstract

Gempa yang diikuti tsunami dan likuifaksi melanda Kota Palu pada 28 September 2018. Sejak saat itu, Kota Palu yang merupakan ibu kota Provinsi Sulawesi Tengah, Indonesia, menjadi pusat perhatian dunia. Berbagai kajian dilakukan untuk memperoleh informasi dari berbagai aspek, antara lain aspek terestrial, perubahan tutupan lahan, batuan, dan perubahan iklim. Teknologi penginderaan jauh memberikan kontribusi yang baik bagi proses penelitian, terutama untuk penelitian yang mencakup wilayah yang luas dan dalam jangka waktu yang lama. Salah satu kajian yang dapat dilakukan dengan menggunakan teknologi penginderaan jauh adalah kajian Suhu Permukaan Tanah (SPT) dengan menggunakan data satelit Landsat-8 multitemporal di Kota Palu. Tujuan dari penelitian ini adalah untuk mendeteksi SPT Kota Palu dari data satelit Landsat-8 multitemporal (2013-2020) dan hubungan antara LST dengan Albedo dan NDVI. Kanal Merah, Biru, NIR, SWIR1 dan SWIR2 digunakan untuk mendapatkan nilai albedo dan NDVI. Nilai emisivitas tanah dan vegetasi serta kanal termal digunakan untuk menentukan nilai LST. Selanjutnya koefisien determinasi (R2) digunakan untuk mengetahui korelasi antara LST dengan Albedo dan NDVI. Hasil dari penelitian ini adalah rata-rata peta sebaran LST dari tahun 2013 hingga 2020. Dari 30 titik sampel penelitian nilai LST antara 17,00 oC sampai 43,27 oC, rata-rata R2 antara LST dan NDVI adalah 0,657 (korelasi kuat), dan R2 antara LST dan Albedo 0,069 (korelasi sangat lemah).
