Abstract

Abstract. A study of HBV hydrological model in Peusangan watershed Aceh as a preface study to the development of sustainable ecohydrological concept was done. The objective of the study was to apply and to test the HBV subtropical model into a tropical region Peusangan watershed. Peusangan watershed, situated in northern Aceh, covers an area of 2268.39 km2 and 128 km in length. The HBV model was manually calibrated by trial adjustment of each parameter to obtain the appropriate physical characteristics of Peusangan watershed. The result showed that the model was nearly consistent with the observation data. In fact, the correlation and error bias of the model were 0.623 and 0.11, respectively. However, the weakness of the model reported in the study is due to the coverage of the weather station data whi ch locate far in the downstream of Peusangan watershed. In the meantime, both of model result and observation showed a good agreement to catch the peakflow of Peusangan watershed. The two peakflow arise on May and October which were 212 m3dt-1 and 250 m3dt-1, respectively.Keywords. HBV Hydrological model, Peusangan watershed, peakflow

Abstract

Abstrak: Penelitian ini menggunakan SIG untuk menganalisis pergeseran zona agroklimat berdasarkan Klasifikasi Schmidt-Ferguson di Kabupaten Gorontalo. Klasifikasi iklim Schmidt-Ferguson diestimasi menggunakan data curah hujan bulanan. Untuk setiap stasiun hujan dari tahun 1981 sampai 2020 dihitung jumlah Bulan Basah (BB), Bulan Kering (BK), dan Bulan Lembab (BL) selama 10, 20, dan 40 tahun. Kabupaten Gorontalo terdeteksi memiliki lima tipe iklim, yaitu: B, C, D, E, dan F. Tipe C mendominasi di stasiun pengamatan selama periode pengamatan 10 dan 20 tahun. Ada kecenderungan luas tipe C menurun sedangkan luas tipe D bertambah, dan iklim kering tipe E dan F berpotensi meningkat. Pemetaan zonasi iklim mempengaruhi sosial ekonomi masyarakat dalam perencanaan pertanian, khususnya pengelolaan lahan dan jenis tanaman. Hasil zonasi iklim yang terdeteksi perlu diverifikasi dengan teknologi penginderaan jauh menggunakan data citra satelit. Hal ini diperlukan karena kelemahan mendasar klasifikasi iklim adalah batas tipe iklim tidak sesuai dengan batas lanskap. Abstract:  This study uses GIS to analyze shifts in agro-climatic zones based on the Schmidt-Ferguson Classification in Gorontalo District. The Schmidt-Ferguson climate classification is estimated using monthly rainfall data. For each rain station from 1981 to 2020, the number of wet months (BB), dry months (BK), and humid months (BL) is calculated for 10, 20, and 40 years. Gorontalo District was detected to have five climate types, namely: B, C, D, E, and F. Type C dominated at observation stations during the 10 and 20-year observation period. There is a tendency for the area of type C to decrease while the area of type D increases, and the dry climate types E and F have the potential to increase. Climate zoning mapping affects the socio-economic community in agricultural planning, especially land management and plant types. The detected climate zoning results need to be verified with remote sensing technology using satellite imagery data. This is necessary because the fundamental weakness of climate classification is that the climate-type boundaries do not match the landscape boundaries.

Abstract

Abstrak: Perkembangan Kota Gorontalo khususnya pada peningkatan jumlah penduduk tiap tahunnya berdampak pada perkembangan kebutuhan akan permukiman. Tujuan penelitian yaitu menganalisis daya dukung lahan permukiman Kota Gorontalo. Gradien lereng, curah hujan, jenis tanah, dan rentan bahaya menjadi parameter perhitungan daya dukung lahan permukiman. Metode analisis menggunakan skoring dan metode overlay. Banyaknya masyarakat, standar ruang/kapita dan ukuran pemukiman yang sesuai merupakan tiga variabel perhitungan dalam menentukan daya dukung lahan permukiman. Hasil analisis kesesuaian lahan pemukiman di Kota Gorontalo diperoleh bahwa 3932,31 Ha lahan berada pada kategori sesuai dan sesuai bersyarat atau 58,7% dari total luas Kota Gorontalo. Luas lahan yang berada pada kategori kurang sesuai dan tidak sesuai adalah 2769,42 Ha atau 41,3%.  Daya dukung lahan pemukiman di Kota Gorontalo diperoleh nilai 7,5 dan nilai jumlah penduduk optimal (JPO) sebesar 1.398.516 jiwa. Apabila jumlah masyarakat meningkat 7 kali dari total penduduk sekarang, maka perhitungan DDPm Kota Gorontalo adalah 1,08. Dengan demikian, daya dukung permukiman tinggi.  Abstract:  The increasing population has an impact on increasing the need for settlements. This research aims to analyze the carrying capacity of settlement land in Gorontalo City. Slope gradient, rainfall, soil type, and disaster risk are the parameters for calculating the carrying capacity of settlement land. The analytical method uses scoring and overlay methods. The number of people, the standard of space requirements, and the size of the appropriate settlement are the three calculation variables in determining the carrying capacity of settlement land. The results of the suitability analysis of residential land in Gorontalo City found that 3932.31 Ha of land were in the category of suitable and conditionally suitable or 58.7% of the total area of Gorontalo City. The area of land that is in the category of less suitable and not suitable is 2769.42 Ha or 41.3%. The carrying capacity of residential land in Gorontalo City is 7.3 and the optimal population value (JPO) is 1,398,516 people. If the number of people increases 7 times the current total population, then the DDPm calculation for Gorontalo City is 1.05. Thus, the carrying capacity of settlements is high.

Abstrak: Kota Gorontalo sebagai Ibukota Provinsi Gorontalo termasuk dalam wilayah yang sering dilanda banjir. Secara hidrologis, Kota Gorontalo dilintasi oleh tiga sungai besar yaitu Sungai Bone, Sungai Bulango, dan Sungai Tamalate. Penelitian ini bertujuan untuk menganalisis persepsi dan strategi adaptasi masyarakat terhadap bencana banjir di Kota Gorontalo. Metode yang diterapkan dalam penelitian ini adalah survey yang menggunakan kuisioner untuk pengumpulan data. Analisis data dalam penelitian ini menerapkan metode analisis deskriptif kuantitatif. Hasil penelitian menunjukkan sebagian besar masyarakat sudah memahami penyebab banjir, namun terdapat 36% masyarakat yang kurang paham dan tidak paham penyebab banjir, dan 94% masyarakat mengetahui akan berulangnya banjir. Dampak banjir yang dialami masyarakat meliputi kerusakan bangunan, gangguan kesehatan masyarakat, hilangnya penghasilan, dan hilangnya ternak. Upaya yang dilakukan masyarakat meliputi upaya fisik dan non fisik. Upaya masyarakat di lokasi penelitian dalam menghadapi bencana banjir meliputi tidak membuang sampah sembarangan, menanam dan memelihara pohon, membersihkan saluran air, dan tidak menebang pohon di hutan. Upaya yang dilakukan masyarakat untuk menghadapi banjir terbentuk dari persepsi untuk bertahan di lokasi rawan bencana banjir dan merupakan bentuk adaptasi masyarakat dalam menghadapi bencana banjir yang sering terjadi untuk mengurangi dampak banjir yang merugikan.Abstract:  Gorontalo City as the capital city of Gorontalo Province is one of the frequently flooded areas. Hydrologically, Gorontalo City is crossed by three major rivers, namely Bone River, Bulango River, and Tamalate River. This research aims to analyze the community's perceptions and adaptation strategies for the flood disaster in Gorontalo City. The method applied in this research is a survey which uses questionnaires to collect data. Data analysis used in this research is quantitative descriptive analysis method. The results showed that most people already understand the causes of flooding, but there are 36% of people who do not understand the causes of flooding, and 94% of people are aware of recurring floods. The impact of flooding experienced by the community includes building damage, public health problems, loss of income, and loss of livestock. Efforts made by the community include physical and non-physical efforts. Community efforts in the research location in dealing with flood disasters include not littering, planting and maintaining trees, cleaning waterways, and not cutting down trees in the forest. Efforts made by the community to deal with floods are formed from perceptions to survive in flood-prone locations and are a form of community adaptation in dealing with flood disasters that often occur to reduce the adverse effects of flooding.

Abstract

Rice stem borer abundance are largely influenced by climate. This research aims to (i) develop a population dynamic model of yellow stem borer (YSB) and (ii) to assess the model's ability to predict abundance and population peak of YSB under climate change scenario SRES A1FI and B1. Modeling the YSB requires two major components: climate parameter and lower developmental threshold temperatures (To) to describe life cycle of YSB from the egg, larva, pupa, and adult stages. The research utilized DYMEX software to describe development, mortality, transfer of individuals from one to the next life stages, fecundity and reproduction of YSB. The coefficient of determination (R2) of calibration models between predictions and observations showed a strong positive correlation of 0.65. Model validation could well predict the peak population, with R2 = 0.42. The simulations showed that the trend of population peak occur at high rainfall i.e. in March to April, July to September, and November to December. The model predicted YSB population in the Sukamandi reaches 3 generations per year, while in Kuningan 2 generations per year. Simulation models under climate change scenarios SRES A1FI and B1 showed differences in the sensitivities. Trend of YSB population is increasing in the regions Kuningan and decreasing in region Sukamandi. Under changing climate, environment conditions in Kuningan become more suitable for the proliferation of YSB, allowing an increase in the number of generations per year.
