Subak merupakan organisasi kemasyarakatan yang ada di Bali yang khusus mengatur sistem pembagian air secara tradisional di sawah untuk bercocok tanam padi. Dengan perkembangan jaman yang pesat ini, keberadaan subak terancam karena adanya alih fungsi lahan ke penggunaan lain di luar sektor pertanian yang menyebabkan ruang terbuka hijau akan semakin berkurang. Jasa lingkungan merupakan jasa yang diberikan oleh fungsi ekosistem yang memiliki manfaat langsung maupun tidak langsung terhadap kehidupan manusia. Penelitian ini bertujuan untuk menganalisis perubahan kualitas tanah yang ada di subak pada saat sebelum tanam dan sesudah panen untuk melihat kontribusi subak terhadap lingkungan. Metode yang digunakan yaitu metode survei dan uji laboratorium untuk menganalisis sifat fisik dan kimia tanah. Pengambilan sampel dilakukan secara purposive sampling, dengan lokasi subak sampel yaitu Subak Kerdung, Subak Jatiluwih dan Subak Lotunduh. Kualitas tanah dinilai dengan menggunakan teknik penilaian berdasakan parameter fisik dan kimia tanah. Parameter yang diamati yaitu sifat fisik tanah yang meliputi tekstur, porositas, kapasitas lapang, berat jenis dan berat volume. Sifat kimia tanah yang dianalisis meliputi pH, N-total, K-tersedia, P-tersedia, KTK dan C-Organik. Hasil analisis menunjukkan perubahan kualitas tanah pada lahan subak sangat baik. Dari segi sifat fisik tanah yaitu meningkatnya porositas menjadikan meningkatnya kemampuan tanah dalam mengikat air. Penurunan berat volume tanah pada masing – masing subak sampel menjadikan tanah lebih gembur sehingga tidak menghambat proses perakaran. Kontribusi subak bagi lingkungan yaitu mampu memberikan stok karbon bagi lingkungan melalui kandungan C-organik yang tersimpan dalam tanah. Subak is a social organization in Bali that specifically regulates traditional water distribution system in rice fields to grow rice. With the rapid development of this epoch, the existence of subak is threatened because of the conversion of land to other uses outside the agricultural sector which causes open green space to be increasingly reduce. Environmental services are the services provided by the ecosystem functions that have direct and indirect benefits to human well being. This research analyzed to changes in soil quality in subak, in the conditions before planting and after harvest an to saw subak contribution to the environment. This study used survey method, physical and chemical soil test in the Laboratory of Soil Science and Environment. The samples were taken by purposive sampling, from Subak Kerdung, Subak Jatiluwih and Subak Lodtunduh. The soil qualities were assessed using scoring technique based on the physical parameters and chemical parameters. The soil physical parameters observed were texture, porosity, roomy capacity and bulk density. The soil chemical parameters observed were pH, N-total, P-available, K-available, CEC and C-Organik. The result of research showed that the change in soil quality on the subak land was very good. In terms of the physical of the soil, the increase in porosity makes the soil ability to bind water increased. Reduction in soil volume weight makes the soil more loose, it does not distrub the rooting process. Contribution of subak to the environment is being able to provide carbon stock to the environment through the C-Organic content stored in the soil as well as meritorius in regulating watter systems and preventing soil erosion.

ABSTRAK Kotoran gajah kaya akan selulosa dan lignin. Kotoran gajah memiliki warna yang bervariasi mulai dari kehijauan hingga kehitaman, tergantung dari makanan yang dikonsumsi (Mathew and Mary 2015). Sementara ini kotoran gajah belum banyak dimanfaatkan Maka dari itu kotoran gajah belum dimanfaatkan secara maksimal. kotoran gajah belum banyak dimanfaatkan secara maksimal. Pengomposan menjadi salah satu pilihan untuk menjadikan kotoran gajah lebih bermanfaat. Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan bioaktivator EM-4 terhadap suhu, pH, kadar air, ratio C/N, bahan organik yang dihasilkan dan untuk menentukan konsentrasi larutan bioaktivator EM-4 yang menghasilkan kualitas kompos yang terbaik dari kotoran gajah dan sesuai dengan Standar Nasional Indonesia (SNI) 19-7030-2004). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL). Perlakuan dengan menggunakan 50 kg kotoran gajah untuk satu perlakuan dan masing masing konsentrasi EM-4 0 ml (kontrol), 50 ml, 100 ml dan 150 ml. Keempat perlakuan tersebut dilakukan pengulangan sebanyak 2 kali sehingga didapatkan 8 unit percobaan. Parameter pengamatan meliputi suhu kompos, pH, Kadar Air, Bahan Organik, Karbon, Nitrogen,C/N ratio. Hasil pengomposan kotoran gajah dengan larutan EM-4 selama 2 bulan, maka dapat dilihat penambahan larutan EM-4 berpengaruh terhadap suhu, kadar air, ratio C/N dan bahan organik sedangkan pH tidak menunjukkan pengaruh yang signifikan. Pada perlakuan penambahan 150 ml EM-4 pada 50 kg kotoran gajah, suhu mencapai termofilik pada hari ke 28 yaitu 46,1 ?C, ratio C/N 19,63 dan bahan organik 35%. Semua perlakuan memenuhi SNI 19-7030-2004. ABSTRACT Elephant dung is rich in cellulose and lignin. Elephant dung has a color that varies from greenish to blackish, depending on the food consumed (Mathew & Mary, 2015). Meanwhile, elephant dung has not been used much. Therefore, elephant dung has not been fully utilized. elephant dung has not been fully utilized. Composting is an option to make elephant dung more useful. The purpose of this study was to determine the effect of the addition of EM-4 bioactivator on temperature, pH, moisture content, C / N ratio, organic matter produced and to determine the concentration of the EM-4 bioactivator solution which produces the best quality compost from elephant dung and in accordance with Indonesian National Standard (SNI) 19-7030-2004). This study used a completely randomized design (CRD). The treatment used 50 kg of elephant dung for one treatment and each concentration of EM-4 0 ml (control), 50 ml, 100 ml and 150 ml. The four treatments were repeated 2 times in order to obtain 8 experimental units. Observation parameters include compost temperature, pH, moisture content, organic matter, carbon, nitrogen, C / N ratio. The results of composting elephant dung with EM-4 solution for 2 months, it can be seen that the addition of EM-4 solution has an effect on temperature, water content, C / N ratio and organic matter while pH does not show a significant effect. In the treatment of adding 150 ml of EM-4 to 50 kg of elephant manure, the temperature reached thermophilic on day 28, namely 46.1 ?C, C / N ratio 19.63 and 35% organic matter. All treatments comply with SNI 19-7030-2004.

Subak in Bali having some wisdom. One of it is an ecological wisdom. The subak ecological wisdom basically based on the Tri Hita Karana (THK) philosophy. UNESCO recognition for subak as a world cultural heritage, because subak directly implemented the THK philosophy in their activities. The components of THK philosophy are parhyangan, pawongan, and palemahan. On parhyangan component, subak is developing harmony on spiritual sector, through some ceremonies at farmer and also at subak level. On pawongan component, subak is developing harmony on social sector, through work together at subak site, and also implementing water borrowing system among subak members in one subak site. Water borrowing system also implemented among subaks that get water from one river. On palemahan component, subak is developing harmony on fisical sector through developing the rice fileds along the land contour, without destroying the land. It’s constructing the beautiful rice field terrace at some subaks in Bali, that it is very famous in the world tourism.
