Sistem subak adalah merupakan salah satu bentuk sistem irigasi yang mampu mengakomodasikan dinamika sistem sosio-teknis masyarakat setempat. Air irigasi dikelola dengan prinsip-prinsip keadilan, keterbukaan, harmoni dan kebersamaan, melalui suatu organisasi yang fleksibel yang sesuai dengan kepentingan masyarakat. Sistem irigasi erat kaitannya tentang pendistribusian air irigasi pada subak yang berdasarkan luas lahan. Salah satu aspek yang akan dinilai dalam sistem irigasi adalah Rasio Prestasi Manajemen (RPM) irigasi Tujuan penelitian ini adalah untuk mengetahui klasifikasi RPM di suatu subak dengan pemberian skor pada masing-masing klasifikasi RPM. Perolehan data sekunder dilakukan dengan metode survey, pengamatan secara langsung dan pengukuran. Data yang telah dikumpulkan selanjutnya akan dianalisis menggunakan metode Rasio Prestasi Manajemen (RPM) Irigasi. RPM irigasi setiap subak dinilai dengan menggunakan empat rentang nilai yaitu Baik bila 0.75 < RPM <1.25, Cukup bila 0.60 < RPM < 0.75 atau 1.25 < RPM < 1.40, Kurang 0.40 < RPM< 0.60 atau 1.40 <RPM<1.60 dan Sangat kurang bila RPM < 0.40 atau RPM >1.60 Hasil metode analisis rasio prestasi manajemen irigasi pada distribusi air di subak diperoleh RPM daerah hulu yaitu Pama Palian, Aya I dan Aya II memiliki RPM yang Baik yaitu rata-rata 100%. Ketersediaan air yang begitu melimpah karena subak daerah hulu, subak yang pertama kali mengambil air di daerah irigasi. Dan yang paling penting adalah sistim pengaturan pemberian air yang sudah optimal. Untuk subak daerah tengah RPM sedikit berbeda dengan di daerah hulu. Rata-rata RPM daerah irigasi tengah yang mempunyai kreteria Cukup yaitu sebesar 15,5% sedangkan Baik 84,5%. Untuk daerah irigasi tengah yang memiliki kriteria RPM cukup dengan nilai 15,5% disebabkan oleh pendistribusian air tidak seoptimal seperti daerah irigasi hulu. Untuk Subak daerah irigasi hilir rata-rata RPM secara keseluruhan yaitu 100% baik, ini disebabkan karena pembagian pendistribusian air daerah irigasi hilir sudah optimal sesuai dengan luas lahan. Subak system is one form of irrigation system that is able to accommodate the dynamics of the socio-technical system of the local community. Irrigation water is managed with the principles of justice, openness, harmony and togetherness, through a flexible organization that is in accordance with the interests of the community. Irrigation systems are closely related to the distribution of irrigation water in subaks based on land area. One aspect that will be assessed in an irrigation system is the Irrigation Management Achievement Ratio (RPM). The purpose of this study is to determine the RPM classification in a subak by scoring in each RPM classification. Secondary data acquisition is done by survey method, direct observation and measurement. The collected data will then be analyzed using the Irrigation Management Achievement Ratio (RPM) method. Irrigation RPM for each subak is assessed using four ranges of values, namely Good if 0.75 <RPM <1.25, Enough if 0.60 <RPM <0.75 or 1.25 <RPM <1.40, Less 0.40 <RPM <0.60 or 1.40 <RPM <1.60 and Very less if RPM <0.40 or RPM> 1.60 The results of the analysis method of irrigation management achievement ratio in the distribution of water in the subak obtained by the upstream area RPM namely Pama Palian, Aya I and Aya II have a good RPM that is an average of 100%. The availability of water is so abundant due to the upstream subak, the first subak to take water in an irrigation area. And the most important thing is the optimal water supply management system. For the subak area the RPM is slightly different from the upstream area. The average RPM of the central irrigation area that has sufficient criteria is 15.5% while 84.5% is good. For the central irrigation area which has sufficient RPM criteria with a value of 15.5% caused by the distribution of water is not as optimal as the upstream irrigation area. For Subak downstream irrigation areas the overall average RPM is 100% good, this is because the distribution of downstream irrigation water distribution is optimal according to the area of ??land.

Biogas is an alternative energy made from organic waste. Organic waste which is often used as raw material for biogas is cow dung. Cow manure is used as raw material for biogas because the cellulose content in it is quite high and its availability is relatively large. However, if only one material is used, the optimum C / N ratio will not be achieved. If the optimum C / N ratio is achieved, the gas produced in biogas production will also increase. One way to get the optimum C / N ratio is by adding biogas filling material. In this study, variations in the composition of biogas filling materials were carried out, namely (1) cow dung, (2) cow dung and sawdust, and (3) cow dung, sawdust, and EM4. Of the three variations of this filling material, measurements of temperature, gas pressure, and pH will be carried out. The purpose of this study was to determine the effect of the composition of the biogas mixture on the variables of temperature, gas pressure, and pH. The biogas production process were divided into several stages, such as mixing filling material, inputting filling material into the digester, fermentation process, taking the data of observation, and analyzing the data. The results showed that differences in the composition of biogas raw materials affected the variable temperature and gas pressure. As for pH, the composition of the filling material does not have a significant effect. Keywords: biogas, cow dung, sawdust, EM4
