Abstrak Daerah tangkapan sungai Komering Hulu memberi kontribusi nyata terhadap daerah aliran sungai Komering Sumatera Selatan. Perubahan penggunaan lahan memberi dampak pada pengurangan kapasitas resapan, akibatnya terjadi ekstrimitas debit seperti banjir dan kekeringan wilayah hilir sungai. Adaptasi dan mitigasi terhadap perubahan penggunaan lahan merupakan upaya untuk mengantissipasi terjadinya kerusakan fungsi hidrologi daerah aliran sungai. Tujuan penulisan adalah mengevaluasi perubahan penggunaan lahan di DAS Hulu terhadap hidrologi daerah aliran sungai. Terjadi perubahan debit rencana 5 tahun kering 126,38 m3/det menjadi 135,88 m3/det (1971-1991 dan 1992-2010). Kenaikan penggunaan lahan terbesar untuk lahan sawah pertanian, tegalan dan kebun sebesar 80,516% yang mengurangi luas hutan menjadi 28%. Perubahan tutupan lahan terutama hutan mengindikasikan kemampuan DAS Komering Hulu untuk menyimpan air. Nilai koefesien limpasan c = 0,399 dan nilai base flow 43,262 didapat trend kenaikkan nilai c dan penurunan nilai b sepanjang tahun 1971-2010. Berdasarkan peta sebaran erosi tahun 1980 dan 2005 menggambarkan DAS Komering Hulu termasuk klasifikasi erosi berat.Abstract Upper Komering catchment areas has contribute substantially to Komering basin , South Sumatera. Land use changing has an impact on reducing the infiltration capacity, lead to extremely flow such as floods and droughts in downstream. Adaptation and mitigation to land use changes is an attempt to anticipate malfunctions watershed hydrology. The purpose of writing is to evaluate land use changing affecting hydrology regime at the watershed. The analysis showed land use changing in several period. There is a changing of design discharge from 126.38 m3 / sec to 135.88 m3 / sec (1971-1991 and 1992-2010). The increase in the use of land for farming paddy fields, moors and yields is 80.516%, which reduces the forest area to 28%. Land cover changing especially forest can be as indicator the capacity of watershed retaining water. Runoff coefficient c = 0.399 and base flow values is 43.262 obtained a trend increase in the value of c and b values decrease during 1971-2010. Based on the distribution maps of erosion in 1980 and 2005 represent Upper Komering watershed including poor classification.

Saat ini Desa Pulau Semambu sedang fokus untuk mengembangkan programwisata edukasi melalui program desa wisata Pulau Semambu. Banyaknya limbahkotoran sapi yang mencapai > 10 Kg per hari membuat limbah kotoran tersebut setiapharinya semakin menumpuk di kandang sapi yang berintergrasi dengan kawasan desawisata Pulau Semambu, hal ini tentunya membuat kandang sapi menjadi akan semakinburuk, karena 100% limbah kotoran sapi, dibuang di samping kandang. Hal inidisebabkan masih minimnya sosialisasi yang diberikan oleh dinas terkait untukpemanfaatan kotoran sapi sebagai bahan baku biogas. Masyarakat masih menggunakan 100% bahan bakar LPG untuk kebutuhan masak sehari ? hari. Berdasarkan potensi limbahkotoran sapi yang ada di Desa Pulau Semambu, Kec. Inderalaya Utara, Kab. Ogan Ilir,maka perlu dilakukan sosialisasi dan penyuluhan berkaitan dengan pemanfaatan limbahkotoran sapi. Bahwa limbah kotoran sapi tidak hanya bisa digunakan sebagai pupukorganik, namun dapat digunakan sebagai penghasil biogas. Hasil dari produksi biogas inidigunakan masyarakat sebagai bahan bakar alternatif pengganti gas LPG untuk memenuhikebutuhan rumah tangga sehari ? hari dan sehingga dapat mengurangi pemakaian gas LPGsebanyak 30% serta dapat menghasilkan pupuk cair dan padat organik yang digunakan padalahan pertanian dan perkebunan.

ABSTRAK Sebagai salah satu bahan bangunan perkembangan beton beton saat begitu pesat, yang merupakan campuran pasir dan kerikilyang ditambah semen dan air. Beton ringan adalah beton yang memiliki berat jenis (density) maksimum sebesar 1.850 kg/m3. Pada proyek bangunan tinggi (high rise building) penggunaan beton ringan secara signifikan dapat mengurangi berat konstruksi. Beton ringan dapat dibuat dengan dengan mengganti agregat kasar maupun agregat halus dengan material yang berat jenisnya lebih ringan. Dalam penelitian ini, penulis menggunaan fly ash sebagai material pengganti aggregat kasar pembentuk beton. Fly ash yang merupakan limbah batubara akan dicampur dengan bahan kimia resin yang berfungsi sebagai pengikat dan perekat dengan perbandingan komposisi agregat 60% fly ash dan resin 40%. Hasil pengujian analisa saringan yang dilakukan terhadap agregat kasar buatan tersebut didapat gradasi agregat kasar adalah jenis kerikil atau koral untuk ukuran maksimum 20 mm dan berat jenisnya adalah 1891 kg/m3 dengan kuat tekan betonnya pada umur 28 hari sebesar 6,85 Mpa. atau mengalami penurunan dari beton normal sebesar 10,92 Mpa (38,55%). Sehingga disimpulkan bahwa beton dengan campuran agregat fly ash 60% dan resin 40% ini belum dapat digunakan sebagai beton ringan struktural karena hasil kuat tekannya yang rendah dibanding dengan beton normal, sehingga hanya dapat digunakan untuk beton ringan non struktural
