Abstrak: Strategi Pengelolaan Limbah Cair Industri Kecil Menengah di Kabupaten Gorontalo Utara. Saat ini Kabupaten Gorontalo Utara memiliki 508 Industri Kecil Menengah. IKM berpotensi menimbulkan dampak negatif melalui limbah yang dihasilkan. Pemerintah Kabupaten Gorontalo Utara telah melakukan antisipasi terhadap segala dampak negatif yang ditimbulkan oleh aktivitas IKM salah satunya dengan mengeluarkan peraturan bupati (PERBUP) Nomor 9 Tahun 2015. Namun kebijakan ini belum efektif diberlakukan. Penelitian ini bertujuan, 1) menganalisis kualitas limbah cair industri kecil menengah di Kabupaten Gorontalo Utara, 2) menentukan strategi kebijakan pengelolaan limbah cair industri kecil menengah di Kabupaten Gorontalo Utara. Metode pengumpulan data dilakukan secara sampling dengan cara mengambil sampel limbah cair di lapangan dan wawancara terhadap pengelola IKM. Data  yang diukur meliputi Suhu, pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total suspended Solid (TSS). Selanjutnya untuk menganalisis strategi pengelolaan limbah cair IKM di Kabupaten Gorontalo Utara, digunakan metode SWOT dengan menganalisis kondisi internal dan kondisi eksternal pengelolaan limbah cair di IKM.  Hasil Analisa laboratorium menunjukkan Konsentrasi BOD, COD, TSS pada IKM tahu dan minyak kelapa berada diatas baku mutu yang mengancam kelangsungan biota perairan dan Kesehatan manusia. Antisipasi terhadap hal ini adalah limbah cair yang dihasilkan harus dapat diolah kembali menjadi bahan yang bernilai ekonomi tinggi Abstract: Management Strategy of small and medium enterprises waste pollution in Gorontalo Regency. North Gorontalo Regency has 508 Small and Medium Enterprises (SME’s) that have the potential negative affects through the waste their produce. The government of North Gorontalo Regency has anticipated the negative impacts caused by SME activities through PERBUP No 9 2015. However, this policy has not been effectively implemented. This study aims to 1) analyze the quality of small and medium enterprises liquid waste in North Gorontalo Regency, 2) determine policy strategies for managing small and medium industrial waste pollution in North Gorontalo Regency. The method of collecting data is by taking samples of liquid waste in the field and interviews with IKM managers. The data measured include Temperature, pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total suspended Solid (TSS). Furthermore, to analyze the SME liquid waste management strategy in North Gorontalo Regency, the SWOT method was used by analyzing the internal conditions and external conditions of liquid waste management in SME. The results of the laboratory analysis showed that the concentrations of BOD, COD, TSS in SME tofu and coconut oil were above the quality standard which threatened the survival of aquatic biota and human health. The anticipation of this is that the liquid waste produced must be reprocessed into materials of high economic value

This study aims at determining the differences in student learning outcomes by involving two classes,i.e. the experimental  classes taugtt by TGT learning model integrated with the STAD learning model as well as the control class taught by the STAD learning model. This experimental research involved all students of grade XI social sciences, namely the experimental class ( XI Social Sciences 2 ) and the control class ( XI Scocial Sciences 4 ).The hypothesis testing results show that the average learnig valuye of the students in the experimental class is 77,43  and the average learning value in the control class is 71,95. Considering the hypothesis testing results in α = 0,05, it is found that tcount = 2,447 ttabel =1.679. This signifies that H0 is rejected ,and the scoes of student who lerning with the TGT cooperative learning model integration with the STAD learning model are higher that students who used the STAD cooperative learning model in Geograhy learning.

ABSTRAK Sub DAS Marisa merupakan salah satu sub DAS yang mengalami kerusakan. Adanya perubahan penggunaan lahan menjadi lahan pertanian mengakibatkan peningkatan terjadinya erosi. Tujuan penelitian adalah untuk menduga potensi erosi dengan aplikasi model Builder pada Sistem Informasi Geografis. Pengukuran potensi erosi menggunakan metode USLE (Universal Soil Loss Equation). Berdasarkan hasil analisis USLE bahwa Sub DAS Marisa nilai erosi tertinggi berada di Kecamatan Limboto Barat dengan luas 7.539,30 Ha. Faktor erosi yang paling berpengaruh di Sub DAS Marisa yaitu faktor CP dan LS. Mayoritas masyarakat merupakan petani sehingga banyaknya lahan pertanian di daerah tersebut. Faktor LS yaitu rata-rata keadan topografi di Sub DAS Marisa yaitu curam dengan kelas kemiringan lereng IV (25%-40%). Di Sub DAS Marisa kurangnya tindakan konservasi yang dilakukan masyarakat, sehingga banyaknya partikel tanah yang terdegradasi terbawa aliran oleh air hujan. Adapun tindakan konservasi yang dapat diterapkan antara lain pemberian mulsa dan penanaman dengan pola sistem agroforestry.  Kata kunci: Erosi; USLE; Aplikasi Builder. ABSTRACT  Marisa sub-watershed is one of the damaged sub-watersheds. The change in land use to agricultural land resulted in an increase in erosion. The purpose of this research is to estimate the erosion potential with the application of the Builder model in Geographic Information Systems. Measurement of erosion potential using the USLE (Universal Soil Loss Equation) method. Based on the results of USLE analysis that the Marisa Sub-watershed has the highest erosion value in the West Limboto District with an area of 7,539.30 Ha. The most influential erosion factors in the Marisa sub-watershed are CP and LS factors. The majority of people are farmers so there is a lot of agricultural land in the area. The LS factor is the average topography in the Marisa sub-watershed, which is steep with slope class IV (25%-40%). In the Marisa Sub-watershed, there is a lack of conservation action taken by the community, so that many degraded soil particles are carried away by rainwater. The conservation actions that can be applied include providing mulch and planting with an agroforestry system pattern. Keywords: Erosion; USLE; Builder Application

ABSTRAKSecara umum perubahan tutupan lahan dan hutan dipengaruhi oleh supply demand, seperti kondisi pertumbuhan ekonomi, peningkatan pendapatan dan adanya peningkatan konsumsi terhadap bioenergy yang naik secara bersamaan. Perubahan fungsi lahan hutan tidak saja berdampak pada kehilangan lahan-lahan produktif tetapi juga menyebabkan adanya pencemaran dan menaikkan pembiayaan fiscal pada daerah yang rusak akibat alih fungsi lahan. Degradasi lahan diperkirakan akan terus meningkat seiring dengan potensi peningkatan potensi perubahan iklim dan berpotensi terjadi dinegara maju maupun negara berkembang. Penelitian ini bertujuan untuk menganalisis dinamika perubahan tutupan hutan dan lahan  di Sub DAS Tamalate DAS Bone Kabupaten Bone Bolango. Berdasarkan hasil analisis spasial sub DAS Tamalate DAS Bone telah kehilangan 17,01 ha hutan dan berubah menjadi pertanian lahan kering. Kawasan pemukiman bertambah seluas 41,99 ha. Situasi berdampak pada makin seringnya banjir yang terjadi pada musim hujan. Deforestasi yang terjadi di sub DAS Tamalate DAS Bone disebabkan karena faktor sosial ekonomi masyarakat seperti, peningkatan permintaan jagung, peningkatan pendapatan petani dan rendahnya control para pihak terhadap lingkungan hidup.Kata Kunci : Deforestasi; Sub DAS Tamalate; DAS Bone.ABSTRACTIn general, forest and land cover changed are influenced by supply and demand such as economic growth condition, both increase income and energy consumption. Forest and land cover change have an impact both productive land and increase financing in area of damages. Land degradation probably increase with climate change in developing countries and developed countries. The aim of research is to analysis dynamics of forest and land cover change in Tamalate Sub Watershed, Bone Watershed. According result of spatial analysis, Tamalate sub watershed, Bone watershed has lost 17,01 forest cover and turned in to dryland agriculture. The residential area expanded to 41,99 ha. The situation has an impact on the more flooding that occurs during rainy season. Deforestation that occurs in Tamalate sub watershed is caused by social economic factors such as increase demand for corn, farmers income and lack of environment control.Keywords: Deforestation; Tamalate Sub Watershed Sub; Bone Watershed
