Judul: Perencanaan Bendungan Tipe Urugan di Perkebunan Cinta Manis, PT. Perkebunan Nusantara VII, Palembang
Abstrak: Perluasan lahan untuk menambah produktivitas tebu di PT. Perkebunan Nusantara VII mengharuskan pembangunan bendungan sebagai suplai air irigasi. Tujuan penelitian ini adalah pembangunan bendungan yang sesuai dengan RSNI T-01-2002. Analisis hidrologi dimulai dengan menentukan luas DAS, perhitungan curah hujan rencana, debit banjir rencana, kebutuhan air, debit andalan dan perhitungan neraca air. Analisis topografi dimulai dari perhitungan volume tampungan, hubungan antara elevasi, luas dan volume genangan. Penelusuran banjir dilakukan untuk mengetahui MAB untuk menghitung dimensi bendungan. Dimensi bendungan dihitung berdasarkan tinggi jagaan dan lebar mercu bendung, kemudian dilakukan analisis stabilitas bendungan. Berdasarkan hasil perhitungan diketahui total volume tampungan sebesar 92650.96 m3. Tinggi bendungan 3.5 m, lebar mercu 6 m dan lebar bawah tubuh bendungan adalah 23.34 m. Hasil analisis stabilitas aliran filtrasi menunjukkan bahwa terdapat garis depresi aliran yang keluar melalui lereng hilir bendungan sehingga diperlukan drainase kaki. Hasil analisis lereng menunjukkan bahwa angka aman (Fs) untuk longsor lebih besar dari syarat yang ditetapkan sehingga bendungan aman dari bahaya longsor.

Judul: Perencanaan Bangunan Pelimpah pada Embung di Perkebunan Bungamayang PT. Perkebunan Nusantara VII
Abstrak: Pabrik Gula Bungamayang, PT. Perkebunan Nusantara VII is one of the sugar cane plantations that the fulfillment of water use reservoir. There’s problem at Petak 093 Afdeling in Rayon II, where the rain caused reservoir water runoff towards to the inspection so that the path becomes difficult pass. As for the goal of this research is planning a spillway of reservoir design so that the normal storage of reservoir constants. Generally, this research was divided into two steps there were preliminary research (flood discharge analysis) and primary research include the analysis of spillway and open channel. Based on observed and researched at Petak 093 Afdeling 09 Rayon II was gained the 25 years return period of flood discharge is 2.96 m3/s by means of used a double circular culvert each 0.80 m of diameter with a space of 0.40 m. Then the flow of water that pass through the culvert continued toward to the 1.85 m of open channel and 4.70 × 2.00 m of basin.

Judul: Pengembangan Model Codebook untuk Identifikasi Chord Gitar
Abstrak: Acoustic guitar can produce sound waves with different types of tones. High-low tone is determined by the fundamental frequency of the sound wave. Human sense of hearing can distinguish high-and low tones, but can not know for sure what kind of tone is heard by him. This study developed a guitar chord recognition system. This study uses MFCC as feature extraction methods and the codebook as pattern recognition method for identification of the guitar chord. Cluster technique used in this study is the K-means clustering. Data obtained from MFCC are clustered using the K-Means method, and the model for classification is constructed using the codebook method. The parameters used in MFCC is the number of cepstral coefficients, overlap, and the time frame, while an important parameter in the K-Means is the number of clusters. This study uses 8640 guitar chord sounds from 24 classes. Each of the data is made up of two chords which will be tested. Simulation results show that the maximum accuracy obtained is 98.89% obtained on 26 cepstral coefficients, overlap 0.4, time frame is 30 ms, on 100 clusters.
