Abstract

Lake Rawa Pening, in Semarang Regency, is one of the super lakes of revitalization priority. Lake revitalization is an activity to restore the natural function of the lake as a water reservoir through lake dredging, cleaning of invasive alien plants, and land use planning. This makes land use and land cover information in Lake Rawa Pening useful for formulating policy strategies related to revitalization. This study will discuss land cover mapping in Lake Rawa Pening. Mapping using Landsat 9 Imagery and machine learning on Google Earth Engine (GEE). Machine Learning used in this study is CART and RF. The research result shows that the land cover map with the best accuracy is obtained from machine learning RF with an overall accuracy of around 0.78, while CART machine learning is approximately 0.76. The overall accuracy values for CART and RF are not much different because they are both decision tree-based machine learning. This research needs to be developed using cloud masking, comparing image transformations, and comparing its predecessor data, namely Landsat 8. This is useful for providing representative land cover data as the basis for the policy of revitalizing Lake Rawa Pening.

Abstract

The relocation of the capital city of Indonesia to Sepaku District, North Penajam Paser Regency, East Kalimantan will have an impact on all existing aspects. Land cover in Sepaku District has decreased from year to year. The area of vegetated land cover in Sepaku District is assumed to be decreasing due to the relocation of the New Capital City (NCC) to the area, which will have a negative impact on the environment. Therefore, this study aims to determine the level of land cover change in Sepaku District and discuss how the condition of land cover in Sepaku District after the construction of the New Capital City (NCC). The method in this study uses GIS (Geographical Information System) analysis and descriptive analysis. The data used are land cover data from 2009 to 2019 to find out changes in land cover and population data from BPS to project the population. Based on the results of the analysis of land cover data from 2009 to 2019 there was a change from scrubland to industrial forest plantations of around 26000 ha. In addition, there was no significant change in the area of built-up land. However, the results of population projections show that Sepaku Sub-district will experience a significant increase in built-up land cover after the construction of the New Capital City (NCC).

Abstract

Kabupaten Grobogan merupakan kabupaten terpadat kedua di Provinsi Jawa Tengah dengan luas wilayah mencapai 197.586,42 dengan tanah sawah seluas 63.955. Kajian kali ini akan berfokus pada perhitungan kebutuhan lahan pertanian di setiap Kecamatan di wilayah Kabupaten Grobogan. Penelitian ini bertujuan untuk memperoleh indeks daya dukung padi di Kabupaten Grobogan tahun 2017 dan 2022 melalui studi dokumentasi. Metode deskriptif kuantitatif digunakan dalam penelitian ini dalam memperoleh data. Pada tahun 2017 rata-rata daya dukung lahan padi di Kabupaten Grobogan yaitu 3,96 (surplus) dan pada tahun 2022 yaitu 3,59 (surplus). Artinya, meskipun wilayah tersebut mampu melaksanakan swasembada pangan atau jumlah penduduk yang berada dalam jangkauan penduduk ideal, namun ada fluktuasi yang terjadi di beberapa daerah. Penurunan indeks selain karena terjadinya penurunan luas lahan panen, juga disebabkan oleh bertambahnya jumlah penduduk. Selain itu, penurunan produksi lahan juga turut serta dalam penurunan klasifikasi kelas pada kecamatan tersebut. Tantangan implementasi daya dukung lahan pertanian berbasis ekoregion adalah data yang masih berbasis administrasi, contohnya adalah data jumlah penduduk dan produktivitas padi. Guna mensiasati hal tersebut, data dapat diintegrasikan dengan pendekatan penginderaan jauh. Pendekatan tersebut bisa dengan transformasi citra indeks vegetasi seperti NDVI maupun EVI.

Abstract

Coconut leaf waste (Cocus nucifera), which contains various beneficial compounds, has not been utilized optimally by the community. Coconut leaves contain a valuable biomass of around 44,000 tonnes/ha to 67,000 tonnes/ha. This has the potential to be used as biochar. The research method used in this research is descriptive experimental research using coconut leaves as raw material for biochar briquettes using a pyrolysis carbonization process. This study used differences in the composition of starch which acts as an adhesive with 3 different variations, namely 2%, 4% and 6%. Based on the results of the ash content test and the calculation of the water content and density, the biochar briquettes in all samples complied with SNI 01/6235/2000.

Abstract

Nipah Panjang Village in Kubu Raya Regency, Indonesia, has diverse mangrove forest vegetation. Meanwhile, the mangrove forest in Nipah Panjang Village has the potential threat of deforestation, so it is necessary to develop a management strategy. A mangrove management directive can be compiled with mangrove biophysical data and the social conditions of the surrounding community. Therefore, this study aims to examine the distribution of mangrove forest areas and their utilization by the community in Nipah Panjang Village. The method used in this study was GIS analysis to determine the distribution of mangrove forest areas. In this study, observations and interviews were carried out to determine the use of mangrove forests. The study results show that from 2013 through 2018, there was around 3.12 Ha of deforestation. Deforestation that occurred was much lower than the previous year. It was due to the implementation of a devolution policy that granted village forest permits in Nipah Panjang Village. Currently, the forms of utilization of mangrove forests in Nipah Panjang Village are the farming (apiculture)  of kelulut honey, forest honey farming, and crab farming with the concept of silvofishery and the development of ecotourism. This form of utilization needs to be maximized so that the community's welfare increases, ultimately maintaining the mangrove forest.
