PEMANFAATAN TEKNOLOGI MODIFIKASI CUACA UNTUK PERKEBUNAN KELAPA SAWIT

IntisariTanaman Kelapa Sawit (Elais sp) adalah sumber utama minyak nabati sesudah kelapa di Indonesia. Tanaman tersebut merupakan komoditi andalan ekonomi Indonesia karena selain merupakan penghasil devisa, kelapa sawit merupakan salah satu alternatif upaya peningkatan kesejahteraan masyarakat melalui pembukaan lapangan pekerjaan dan lapangan usaha. Distribusi tanaman kelapa sawit di Indonesia dapat dijumpai di setiap pulau seperti Sumatera, Kalimantan, Sulawesi dan Jawa. Pada tahun 2013, dari total luas perkebunan kelapa sawit sebesar 9,14 juta hektar, sekitar 65% berada di pulau Sumatera, disusul Kalimantan (31%), Sulawesi (3%), kemudian Jawa dan Papua di bawah satu persen. Tanaman kelapa sawit tergolong ke dalam tanaman xerophyte yang dapat beradaptasi dengan kondisi air yang kurang, walaupun demikian tanaman tetap akan mengalami gejala stres air pada saat musim kemarau yang berkepanjangan. Salah satu upaya untuk mengantisipasi musim kemarau panjang dan kebakaran lahan yaitu dengan melakukan Teknologi Modifikasi Cuaca (TMC). Penerapan TMC di Indonesia sudah dilakukan sejak tahun 1979 dengan berbagai tujuan, yaitu menambah curah hujan untuk mengatasi kekeringan, pengisian air waduk untuk irigasi dan PLTA; mengurangi curah hujan untuk mengatasi banjir; longsor; dan mengurangi kabut asap akibat kebakaran hutan dan lahan. Simulasi proyeksi curah hujan dengan skenario pelaksanaan TMC 120 hari dilakukan di wilayah Riau, Kalimantan Tengah dan Sumatera Utara sebagai daerah dengan luas perkebunan sawit terbesar di Indonesia. Hasil dari simulasi tersebut adalah menghitung besarnya jumlah curah hujan tahunan yang dapat dihasilkan apabila dilakukan TMC 120 hari pada bulan April-Mei 2014 dan Agustus-September 2014 dengan asumsi tingkat pertambahan hujan ketika berada pada periode penyemaian awan sebesar 30%. Berdasarkan hasil simulasi curah hujan dengan skenario pelaksanaan TMC 120 hari, untuk wilayah Riau akan didapatkan penambahan curah hujan sebesar 198 mm/tahun, wilayah Kalimantan Tengah sebesar 254 mm/tahun dan wilayah Sumatera Utara sebesar 233 mm/tahun. Abstract Palm (Elais sp) is the main source of vegetable oil after coco in Indonesia. This plant is mainstay commodity of Indonesia because in addition to foreign exchange earner, palm oil is one alternative efforts to improve the welfare of society through the opening of employment and business field. Distribution of palm oil plantations in Indonesia can be found in every island like Sumatra, Kalimantan, Sulawesi and Java. In 2013, total area of palm oil plantations amounted to 9.14 million hectares, approximately 65% were on the island of Sumatra, Kalimantan followed (31%), Sulawesi (3%), then Java and Papua under one percent. Palm oil plants belonging to the plant xerophyte that can adapt to conditions that are less water, however the plant will continue to experience symptoms of water stress during the long dry season. One effort to anticipate the long dry season and forest fires by performing the Weather Modification Technology. Application of this technology in Indonesia have been carried out since 1979 with a variety of purposes, namely to rain enhancement to overcome drought, filling water reservoirs for irrigation and hydropower; reduce rainfall to overcome floods; landslides; and reduce smog from forest fires and land. Simulation of rainfall projection with applying weather modification technology for 120 days in Riau, Central Kalimantan, and North Sumatra as the area with the largest palm oil plantations in Indonesia. Result of this simulation is to calculate the amount of annual rainfall if weather modification for 120 days applied in April-May 2014 and AugustSeptember 2014, assuming growth rate when cloud seeding period is 30%. Based on this simulation resulted for Riau regoin will get additional rainfall 198 mm/year, Central Kalimantan Region 254 mm/year and North Sumatra Region 233 mm/year

Forest Fire Management

Forest fire is one of environmental problem happens in Central Kalimantan. The fire does not only damage the forest ecosystem and biodiversity but also threaten the health and socio-economic of local people. Forest fire in Central Kalimantan is widely known as human-made, such as the process of shifting cultivation and land clearing. The expansion of forest into palm oil plantation is often blamed as the cause of forest fire since the forest clearing involves a massive amount of fires. Therefore, this study aims to explore whether the existence of palm oil cultivation contributes to the occurrence of forest fires. We used satellite imagery of hotspot, and overlay it with the land use data to generate the fire risk zone map using geographic information system (GIS) method. Through the map, the risk of fire can be monitored in advance to help the fire authority provide the act of mitigation. The result of this study suggested that risk mapping is vital for forest fire management to mitigate the spread of forest fire. The region to be fire-prone within the palm oil cultivation is suggested to form a preventive act through active forest-fires monitoring. In sum, this study is expected to provide a map of forest fires' risk around the cultivation area, mainly palm oil plantation, and help the fire authorities as well as stakeholders to identify the risk zone for fires prevention in the future.

Abstract Background Fire is an important process that shapes the structure and functioning of African savanna ecosystems, and managers of savanna protected areas use fire to achieve ecosystem goals. Developing appropriate fire management policies should be based on an understanding of the determinants, features, and effects of prevailing fire regimes, but this information is rarely available. In this study, we report on the use of remote sensing to develop a spatially explicit dataset on past fire regimes in Majete Wildlife Reserve, Malawi, between 2001 and 2019. Moderate Resolution Imaging Spectroradiometer (MODIS) images were used to evaluate the recent fire regime for two distinct vegetation types in Majete Wildlife Reserve, namely savanna and miombo. Additionally, a comparison was made between MODIS and Visible Infrared Imager Radiometer Suite (VIIRS) images by separately evaluating selected aspects of the fire regime between 2012 and 2019. Results Mean fire return intervals were four and six years for miombo and savanna vegetation, respectively, but the distribution of fire return intervals was skewed, with a large proportion of the area burning annually or biennially, and a smaller proportion experiencing much longer fire return intervals. Variation in inter-annual rainfall also resulted in longer fire return intervals during cycles of below-average rainfall. Fires were concentrated in the hot-dry season despite a management intent to restrict burning to the cool-dry season. Mean fire intensities were generally low, but many individual fires had intensities of 14 to 18 times higher than the mean, especially in the hot-dry season. The VIIRS sensors detected many fires that were overlooked by the MODIS sensors, as images were collected at a finer scale. Conclusions Remote sensing has provided a useful basis for reconstructing the recent fire regime of Majete Wildlife Reserve, and has highlighted a current mismatch between intended fire management goals and actual trends. Managers should re-evaluate fire policies based on our findings, setting clearly defined targets for the different vegetation types and introducing flexibility to accommodate natural variation in rainfall cycles. Local evidence of the links between fires and ecological outcomes will require further research to improve fire planning.

Rainfall is the key element in regional water balance, and have direct influence over economic activity. In this study, we evaluate the estimates of precipitation by TRMM satellite (Tropical Rainfall Measuring Mission) on the Midwest region of Brazil. The rainfall measured by TRMM satellite was compared with rainfall series obtained by the Office of Instituto de Controle de Espaço Aéreo (ICEA) of Comando da Força Aérea. The TRMM satellite overestimated annual rainfall between 0.6 and 37.4%, with greater overestimation in the dry season. However, the rainfall estimate by TRMM satellite had a high correlation (0.88) with the rainfall series and had high Willmott coefficient. The Northern of Brazilian Midwest had the highest annual accumulated rainfall and the Southwest and Northeast of Midwest had the lowest annual accumulated rainfall. There was a inverse seasonal pattern of accumulated rainfall, with higher values in the Northern of Midwest during the rainy season in the Southwest and Northeast during the dry season.

ABSTRAKEmisi metana (CH4) dari pertanian padi lahan sawah dapat dipengaruhi oleh faktor-faktor seperti cara pemberian air, pengolahan tanah, varietas padi, dan iklim. Pada penelitian ini dikaji tahap penentuan musim tanam, pemilihan varietas padi, dan tahap terakhir adalah teknik budidaya pertanian padi lahan sawah yang terkait mitigasi emisi CH4. Hasil kajian menunjukkan bahwa musim tanam padi pada musim kemarau menghasilkan emisi CH4 lebih kecil daripada di musim hujan dengan pengurangan emisi CH4 sebesar 18,13%. Indonesia yang memiliki tiga tipe pola curah hujan tahunan (monsunal, equatorial, lokal) mengakibatkan periode musim tanam rendah emisi CH4 berbeda antara tipe curah hujan yang satu dengan lainnya. Varietas padi Way apo buru adalah varietas yang menghasilkan emisi CH4 terendah tetapi tetap optimum dalam produksi gabah sehingga dapat dipilih menjadi prioritas pertama untuk ditanam. Teknik budidaya pertanian padi lahan sawah yang menghasilkan rendah emisi CH4 dapat dilakukan dengan membuat genangan air yang dangkal saja, dengan cara pemberian air berselang, dan kombinasi antara pemeliharaan padi, ganggang, tanaman paku air, ikan air tawar, dan bakteri metanotrof dalam satu petak lahan sawah (mina padi plus). Pemberian air dengan cara berselang menurunkan emisi CH4 pada musim kemarau sebesar 59,36% dan pada musim hujan sebesar 51,68% jika dibandingkan dengan pemberian air secara terus-menerus (kontinyu). Teknik budidaya mina padi plus mengurangi emisi CH4 sebesar 21,5 kg/ha/musim tanam dan bakteri metanotrof mengurangi emisi CH4 ke atmosfer sebesar 20-60 Tg. Sawah dapat dijadikan sebagai instalasi terbuka pengolahan udara berlimbah CH4. ABSTRACTMethane (CH4) emissions from rice cultivation can be influenced by several factors i.e. the provision of water, soil cultivation, varieties of rice, and the climate. This study will examine the determination of the growing season, the selection of rice varieties and cultivation techniques of rice agriculture-related wetland mitigation of the CH4 emission. The results showed that the rice planting season in the dry season produces CH4 emissions is smaller than in the rainy season with CH4 emission reduction of 18.13%. Indonesia, which has three types of annual rainfall patterns resulting in periods of low growing season CH4 emissions differ between types of rainfall each other. Way apo buru rice species are varieties that produce low emissions of CH4 but remains optimum in grain production. Cultivation techniques of rice farming rice fields that produce low emissions of CH4 can be done by creating a pool of shallow water only, by way of provision of water intermittent, and the combination of maintenance of rice, algae, plants salviniales, freshwater fish, and bacteria metanotrof in a wetland. The provision of water by intermittent lowering emissions of CH4 in the dry season by 59.36% and in the rainy season amounted to 51.68% when compared to the provision of water continuously (continuous). Mina padi plus cultivation techniques reduce CH4 emissions by 21.5 kg/ha/planting and metanotrof bacteria can reduce CH4 emissions to the atmosphere by 20-60 Tg.

Abstract Damage to conservation areas in North Sumatra can be mitigated by understanding the pattern of land cover change, which can be performed by detecting hotspots and their temporal and spatial patterns. This study aimed to explore land cover spatially and temporally before and after forest fires in the conservation areas in North Sumatra. Data on the hotspots, satellite imagery, land cover maps, and field verification were used to see the transition of land cover changes before and after forest and land fires. Temporal and spatial analysis was employed to see the trend of land cover changes of the land before and after the fires. Field verification was conducted through observations and interviews related to land cover conditions in the field caused by forest and land fires. This study found three conservation areas with the highest number of hotspots in 2014 in the period 2001-2019, including Gunung Leuser National Park (GLNP), Dolok Surungan Wildlife Reserve, and Barumun Wildlife Reserve during the 2001-2019 period. In 2010 and 2014 there were strong indications of a large area of land burning in three conservation areas. The burned land was near the outer boundary of the conservation areas and continued to expand into the areas over time. The area of the non-forest cover was relatively stable between periods prior to the discovery of several hotspots. Changes in forest cover to non-forest have become more widespread after the highest number of hotspots were detected in 2010. Conservation area management and various parties need to prevent the expansion of forest clearing considering the strategic role especially in GNLP as a world heritage.
