Indonesia's rapid population growth will indirectly affect the increase in waste production. Ineffective and efficient waste management systems will have an impact on the accumulation of waste at the final processing location. Large piles of garbage have the potential to produce gases that are harmful to health and the environment. Jatibarang Final Processing Site is the only final processing location in the city of Semarang, where the final processing location can accommodate sources of waste from 16 sub-districts in the city of Semarang. The purpose of this study is to determine the waste management activities in the Jatibarang final processing site, so that later it can become an input to improve future waste management in the Jatibarang final processing location. The research method used is descriptive qualitative, using primary and secondary data collection techniques.The results of the study explained that the waste management activities at the jatibarang final processing site are, the final scraping of compost, the use of methane gas (CH4) originating from the landfill as an alternative gas (biogas), reducing waste by herding cattle, and the methane canteen program.Keyword: waste, management, Jatibarang ABSTRAKPertumbuhan penduduk Indonesia yang cepat akan secara tidak langsung mempengaruhi peningkatan produksi limbah. Sistem pengelolaan limbah yang tidak efektif dan efisien akan berdampak pada akumulasi limbah di lokasi pemrosesan akhir. Tumpukan besar sampah berpotensi menghasilkan gas yang berbahaya bagi kesehatan dan lingkungan. Situs Pengolahan Akhir Jatibarang adalah satu-satunya lokasi pemrosesan akhir di kota Semarang, di mana lokasi pemrosesan akhir dapat menampung sumber limbah dari 16 kecamatan di kota Semarang. Tujuan dari penelitian ini adalah untuk mengetahui kegiatan pengelolaan limbah di lokasi pengolahan akhir Jatibarang, sehingga nantinya dapat menjadi input untuk meningkatkan pengelolaan limbah di masa mendatang di lokasi pengolahan akhir Jatibarang.

Hasil penelitian menjelaskan bahwa kegiatan pengelolaan limbah di lokasi pemrosesan akhir jatibarang adalah, pengikisan akhir kompos, penggunaan gas metana (CH4) yang berasal dari TPA sebagai gas alternatif (biogas), mengurangi limbah dengan menggembalakan ternak , dan program kantin metana.Kata kunci: limbah, pengelolaan, Jatibarang

Development of a city is something that cannot be avoided and will continue to happen dynamically from time to time. Along with the development of various urban activities, where the population as a means of implementation has a direct impact on the increasing demand for land. Semarang City, which is the capital of Central Java Province, is also one of the centers for the growth of trade and services, education and service centers for other activities, which have developed very rapidly. This is what stimulates the flow of urbanization in the city of Semarang with the aim of getting a more decent life which will have an impact on the development of built-up land. The purpose of this study is to identify developments and factors that affect built-up land in the city of Semarang as an effort to monitor and anticipate to prevent unwanted negative impacts in the future. Through secondary data collection and continued with analysis using the Supervised Classification method, the results showed that there was a change in land use into built-up land in Semarang City from 1999-2019 covering an area of 11,403.46 Ha or an increase of 29.36%. Based on the results of the analysis of the level of development of built-up land using the quantitative method, it was found that three sub-districts with the category of very high development of built-up land in Semarang City were Ngaliyan District, Mijen District and Tembalang District. Based on multiple linear regression analysis, the equation Y = 20.453 + 0.007X1 + 38.425X2 - 6.775X3 + 3.170X4 and has an R² of 0.835. This means that the independent variables (independent) namely population (X1), distance to the city center (X2), land value (X3) and public facilities (X4) have an influence of 83.5% on changes in built-up land while the remaining 0.165 or 16.5% influenced by other variables not explained in this study.

Abstrak. Secara umum perkembangan ruang kora dipengaruhi oleh perubahan yang menyeluruh pada aspek sosial, disik, budaya, dan ekonomi. Terkait dengan perkembangan fisik kota, perkembangan ruang Kabupaten Semarang termasuk dalam kategori cukup cepat, terutama terkait dengan perkembangan Kota Semarang pada bagian utara dan dibangunnya jalan tol Semarang-Bawen. . Dengan memanfaatkan teknologi penginderaan jauh dan citra satelit, perkembangan tersebut dapat dipetakan dan dianalisis pola perkembangannya. Tujuan penelitian ini adalah untuk mengidentifikasi pola perkembangan ruang di Kabupaten Semarang dengan memanfaatkan data citra landsat multitemporal. Penggunaan citra landsat ini dapat menjadi alat dalam monitoring dan pengendalian perkembangan kawasan perkotaan terutama terkait dengan proses urbanisasi di pada kota-kota menengah di Jawa Tengah seperti halnya di Kabupaten Semarang. Hasil pengolahan analisis dari citra satelit adalah data lahan terbangun. Selama kurun waktu 43 tahun (1972 s/d 2015) perubahan lahan yang terjadi di Kabupaten Semarang bertambah 13.000 Ha atau rata-rata 300 Ha/tahun. Perubahan lahan terbesar berada di Kecamatan Tengaran, Susukan dan Bergas yaitu lebih dari 20 Ha/tahun. Perubahan lahan terbangun tersebut memberikan gambaran terhadap perubahan ruang kota.Kata kunci: citra landsat; perkembangan ruang; lahan terbangun [Tittle: Growth of Spatial Pattern of Semarang Regency by Using Remote Sensing Data].The development of the city is influenced by the growth on the physical, economic, and social activities in the city. In the case of Semarang Regency, this development is included in the category fairly fast, particularly after the opening of toll road Semarang-Bawen. By utilizing remote sensing technology and satellite imagery, the pattern of these developments can be mapped and analyzed. The purpose of this study was to identify the pattern of development of space in Semarang Regency by using multitemporal Landsat images. The application of these images can be a mean of monitoring and controlling mechanism of the urban growth in the fast growing city in Central Java, such as in Semarang Regency. Hence, the focus of this analysis is on data of built up area. During the period of 43 years (1972 -2015) land use change that occurred in the district of Semarang had increased for about 13,000 Ha or an average of 300 ha/year. The biggest changes are located in the Tengaran, Susukan and Bergas sub district that grow more than 20 ha / year.
