Perubahan penggunaan lahan bisa dibilang kekuatan sosioekonomi yang paling meluas mendorong perubahan dan degradasi ekosistem (Wu, 2008). (Kodoatie, 2010) menyatakan bahwa, terganggunya siklus hidrologi telah menimbulkan “3 T” masalah klasik air “too much (yang menimbulkan banjir), “too little (yang menimbulkan kekeringan) dan “too dirty (yang menimbulkan pencemaran air). Berdasarkan data BNPB tahun 1979-2009 terdapat 8 kejadian kekeringan di Provinsi Gorontalo. Penelitian ini bertujuan (1) mengetahui tingkat kerentanan DAS Limboto terhadap kekeringan. (2) menyusun arahan penggunaan lahan pada DAS Limboto berdasarkan penentuan tingkat kerentanan kekeringan. (3) mengsimulasikan arahan penggunaan lahan dalam rangka pengendalian kekeringan di DAS Limboto. Penelitian ini dilaksanakan pada Daerah Aliran Sungai (DAS) Limboto dengan luas DAS 86412,6 ha. Metode yang digunakan adalah Metode SWAT (Soil and Water Assessment Tool) dengan menggunakan software ArcSwat yang terintegrasi SIG. Penelitian ini termasuk dalam penellitian non-eksperimen yakni dengan menggunakan pengamatan langsung di lapangan. Input data SWAT antara lain lereng, jenis tutupan lahan, iklim, dan jenis tanah. Analisis yang digunakan dalam menentukan kerentanan DAS terhadap kekeringan adalah dengan menggunakan Soil Moisture Deficit Index (SMDI) melalui parameter Soil Water (SW). Pada penelitian ini penggunaan output model SWAT melalui ArcSwat, telah mampu menggambarkan kondisi pasokan air pada DAS Limboto, yang secara keseluruhan telah termasuk dalam kategori “Rentan”. Dengan membandingkan luas area yang mengalami kekeringan pada sebelum dan setelah dilakukan simulasi/running arahan penggunaan lahan maka dapat disimpulkan bahwa selisih luas area DAS yang mengalami kekeringan dengan klasifikasi “Rentan” diperoleh 37.513,1 ha atau secara persentasi mengalami penurunan sebesar 43,4 % dari luas DAS.

Publisher : LPPM Universitas Muhammadiyah Gorontalo

Research on the morphology of a form of land can be done by field survey method and utilization of data to do modeling of land. Based on this, the morphological characteristics of Bukit Hundulobohu are interesting to be investigated by using lithology and SRTM data. In collecting and analyzing field data and SRTM obtained that Bukit Hundulobohu rocks are composed of tuff sandstone, limestone and loose material. The high difference of research area is 2 - 5 meter with slope of 2 - 7%. The research relief classes are included in flat or nearly flat relief classes and corrugated relief classes / slopes of slopes. Characteristics of research areas that are somewhat skewed causing movement of soil in this area tend to be low but including erosion prone. The dangers of erosion are greater with the discovery of litative tuffs and obsolete limestone in the study area. Tuf pasiran and limestone is also a rock that is not resistant Penelitian terhadap morfologi suatu bentuklahan dapat dilakukan dengan metode survei lapangan dan pemanfaatan data-data untuk melakukan pemodelan bentuklahan. Berdasarkan hal ini maka karakteristik morfologi Bukit Hundulobohu menarik untuk diteliti dengan menggunakan data litologi dan data SRTM. Pada pengumpulan dan analisis data lapangan dan SRTM diperoleh bahwa batuan Bukit Hundulobohu tersusun atas batuan tuf pasiran, batugamping dan material lepas. Beda tinggi daerah penelitian adalah 2 – 5 meter dengan kemiringan lereng 2 – 7 %. Kelas relief daerah penelitian termasuk dalam kelas relief datar atau hampir datar dan kelas relief bergelombang/lereng landai. Karakteristik daerah penelitian yang agak miring menyebabkan gerakan tanah pada daerah ini cenderung rendah namun termasuk rawan erosi. Bahaya erosi semakin besar dengan ditemukannya litologi tuf pasiran dan batugamping yang sudah lapuk pada daerah penelitian. Tuf pasiran dan batugamping juga merupakan batuan yang tidak resisten.

Drought is one of the greatest disasters that will be experienced by humans at the end of time. The level of drought in the Limboto watershed is in the vulnerable category, so special handling is needed as an effort to mitigate this disaster. This study aims to (1) determine the Muhammadiyah propaganda model in the District of Bongomeme, Gorontalo Regency (2) determine the community's understanding of the Muhammadiyah propaganda in the District of Bongomeme, Gorontalo District. The use of mixed methods (qualitative and quantitative) forms the basis of this research. In the qualitative method, the data collection of da'wah models is done through observation, interviews and documentation. Whereas quantitative data is carried out through questionnaires. Based on the results of the study obtained a link between the high drought and the level of understanding and application of Islamic religious values and preachers of Muhammadiyah. This is indicated by the value obtained on average 1.75, which means the level of public understanding is still in the bad category. As for the level of mastery of preaching material on drought, a similar value is obtained, which is 1.85, which means that very little material preaching by Muhammadiyah preachers contains about the drought.

Abstract - Changes in land use are the socio-economic forces that most encourage changes and ecosystem degradation. Disruption of the hydrological cycle has caused "3 T" classic problems of water "too much (which causes flooding)," too little (which causes drought) and "too dirty (which causes water pollution). Based on data from BNPB in 1979-2009 there were 8 drought events in Gorontalo Province. This research was carried out in the Limboto Watershed with an area of 86412.6 ha. The method used is the SWAT Method (Soil and Water Assessment Tool) using ArcSwat software that integrates GIS. This research is included in non-experimental research that is by using direct observation in the field. Input of SWAT data include slope, land cover type, climate, and soil type. The analysis used in determining the vulnerability of the watershed to drought is to use the Soil Moisture Deficit Index (SMDI) through the Soil Water (SW) parameter. In this study the use of SWAT model output through ArcSwat, has been able to describe the condition of water supply in the Limboto watershed, which as a whole has been included in the "Vulnerable" category. By comparing the area that experienced drought before and after simulation / running land use directives, it can be concluded that the difference in the area of the watershed that experiences drought with the "Vulnerable" classification is obtained 37,513.1 ha or a decrease of 43.4% from watershed area.

The Batulayar sub-watershed, also known as the Bongomeme sub-watershed, is one of the most important sub-watersheds in the Limboto watershed. Because there are oil palm and other plants in the Batulayar Sub-upstream watershed's area that cause drought and natural harm. The goal of this study was to assess the severity of the drought and develop a hydrological model for calculating the drought index in the Batulayar sub-upstream watershed's area. The mix approach was utilized, which combines Soil and Water Assessment Tool (SWAT) modeling with field survey methodologies. The study's findings suggest that land conversion in the Batulayar Sub-upstream watershed's area may have an impact on the watershed's function. The Batulayar Sub-SMDI watershed's value in the SWAT Model results shows that it ranges from -0.50 to -2.99 in March, April, May, November, and December over a 10-year period, and is classified as "Slightly Dry" and "Slightly Dry." The Hydrological Model's role in determining the drought index can be seen in the results of calibration and validation using the NSE Model (Nash Sutcliffe Coeficient of Efficiency). An NSE value of 0.9 is obtained in calibration and validation, implying that the NSE value obtained belongs to the "good" class or that the discharge model and research observation discharge are similar.

Batulayar is one of the small watersheds contained in the Limboto / Large watersheds. Where the Limboto watershed as a whole is in the category of drought prone (Ayuba dkk, 2018). The aim of this study; know the availability of the Batu Layar Watershed through SWAT modeling. The method used in this study is the Soil and Water Assessment Tool (wateryield parameter / WYLD) to obtain water availability data. Based on the results of the SWAT analysis, Sub Basin 45 has the largest WYLD value of 626.5 mm, which is administratively located in Molanihu Village. While Sub Basin 32 is a sub basin with the smallest WYLD value of 421.5 mm and administratively this sub basin is located in Pangadaa Village. The value of water which is the result of the accumulation of surface, lateral, and base flow where these three flow patterns determine further planning related to handling the problem of water availability. This indicates that Pangadaa Village has a deficit in water availability when compared to other villages. This needs to be controlled for the conversion of land functions considering that this area is used as dry land agriculture by the community which can result in the threat of water management in this sub basin.

In the Alo sub-watershed, the study compares the rates of various types of land use. The Alo sub-watershed is 7,959.98 areas in total. Measurement of infiltration rates for various land uses in the Alo sub-watershed and analysis of differences in infiltration rates for various land uses in the Alo sub-watershed are the problems at hand in this study. The Horton method was used in this study's infiltration measurements. This approach uses a model of time-dependent empirical equations. It is known that multiple infiltration categories exist for plantations, villages, vacant land, bushes, and woods in the infiltration rate class for the kind and usage of dry land used in this study's Alo sub-watershed. It has classes for Fast, Moderate, and Moderate infiltration rates. For the type of land use and paddy field, the infiltration rate falls into the category of being fairly slow. This is due to the high water content of paddy fields, which makes the infiltration process take a while to complete. As a result, the infiltration rate in the Alo sub-watershed, Tibawa District, Gorontalo Regency, and Gorontalo Province reveals that the medium class dominates in the Alo sub-watershed. The cumulative infiltration rate or total amount of infiltrated water is 123,899 mm/hour at point 14 types of vacant land, and 8,476 mm/hour at point 16, which is the smallest cumulative value. The infiltration rate class in the Alo sub-watershed, Tibawa District, Gorontalo Regency, and Gorontalo Province reveals that the Medium Class dominates the sub-watershed.
