Sanur is one of five Sustainable Tourism Observatory (STO) in Indonesia. As the oldest tourist resort in Bali, Sanur Tourist Resort couldn’t avoid various problems. Jasmine hotel in this area must face the same problems, such as fresh water crisis. Responding to this, Indonesian’s Tourism Ministry appealed to the entire hotels to develop eco-friendly tourism through an environmental audit on The Green Hotel program. Thus, the hotels should conduct various efforts towards sustainable tourism. This research was conducted in order to find out the performance of jasmine hotels in Sanur Tourist Resort in implementing Green Hotel principles, related to water conservation. Data were collected between August and December 2018 through observation, interviews, distributed questionnaires, literature study and checking documents. The data were qualitatively and quantitatively analysed. The results showed that in Sanur Tourist Resort, the implementation of water conservation has been implemented well by 23.08% of jasmine hotels only but 76.92% of them have not did it well.
In Indonesia agriculture practice often used the large scale pesticide application such as insecticide, herbicide, and fungicide. The wide use of toxic pesticide has created numerous problem in increasing environtmental hazard to human and to other animals. Many of soil bacteria had important role to degrading chemical compounds into simpler compounds as a bioremediation agent. The aim of this study was to screen the Chlorantraniliprole tolerant bacteria using soil mineral medium with Prevathon pesticide addition, also teo identificate the species of bacteria. This research was conducted at Microbiology Laboratory, Faculty of Mathematics and Natural Sciences, Udayana University. The research was done in three analysis, (1) bacteria test on Prevathon pesticide addition to mineral medium treatment, (2) characterization of bacteria, (3) Identification of pesticide tolerant bacteria with BD BBL Crystal Enteric/Non FermenterID Kit. The results showed that mineral medium with the addition of pesticides Prevathon treatment able to provide a significant different effect on the enrichment stage 1, stage 2 and stage 3 (P<0.05), there was 5 isolates pesticide tolerant bacteria that isolated from Baturiti Tabanan cultivated soil that was BSP 1, BSP 2, BSP 3 known as gram negative bacteria, and BSP 4, BSP 5 known as Gram positive bacteria, pesticide tolerant bacteria identified as Serratia marcescens which is a Gram negative bacteria group and may cause pathogenic.
INTISARI Keberadaan gulma pada tanaman padi akan menyebabkan penurunan produksi apabila gulma tidak dikendalikan secara efektif, karena dapat mempengaruhi pertumbuhan dan menurunkan produksi tanaman pangan. Penelitian ini bertujuan untuk mengetahui keanekaragam jenis gulma yang tumbuh pada tanaman padi (Oryza sativa L.) di Desa Cempaga, Kecamatan Bangli, Kabupaten Bangli, mengetahui jenis gulma yang tumbuh pada tanaman padi (Oryza sativa L.), dan jenis gulma apakah yang dominan pada tanaman padi (Oryza sativa L.). Penelitian ini dilaksanakan di Desa Cempaga Kecamatan Bangli Kabupaten Bangli pada bulan Maret-Mei 2020. Pengumpulan data dilakukan dengan analisis vegetasi menggunakan metode kuadrat dengan cara random menggunakan lotre atau undi dimana pengambilan sampel dilakukan sebanyak tiga kali yaitu pada minggu ke-8, ke-10, dan ke-12 dengan interval waktu pengambilan yaitu sekali dalam 2 minggu sehingga jumlah sampel yang diambil setiap 2 minggu yaitu 15 plot dengan ukuran 1x1m, dan data yang diambil yaitu jenis gulma yang terdapat didalam plot. Hasil pengamatan keberadaan jenis gulma menunjukkan bahwa jenis-jenis gulma yang tumbuh di lokasi penelitian cukup bervariasi, terdapat 781 individu, 12 jenis dan 8 suku, dimana gulma yang paling banyak muncul di plot yaitu tumbuhan Pusut-pusut muncul di 23 plot dan memiliki dominansi relatif yaitu sebesar 49,31%, sedangkan gulma yang paling sedikit muncul yaitu Paku Rawa hanya muncul di satu plot dengan memiliki nilai dominansi relatif yaitu 0,00%. Dimana artinya tumbuhan yang paling berpotensi mengganggu tanaman pokok yaitu tumbuhan Pusut-pusut dengan pola penyebaran yang mengelompok. Nilai INP tertinggi terdapat pada jenis gulma Pusut-pusut dengan nilai sebesar 103.45%. Kata Kunci : Desa Cempaga, Gulma, Padi Sawah
Compost is an organic fertilizer made from recycled organic materials. Fertilizers can be made from organic waste or unused organic waste. Purple sweet potato waste can be reused into compost. The purpose of this study was to examine the effectiveness of purple sweet potato waste compost inoculated with Trichoderma harzianum in increasing the production of pakchoi and to determine the treatment of purple sweet potato waste compost to increase the production of pakchoi. The research method used is the experimental method. The experimental design used was RAK (Randomized Block Design) with 1 factor. The experiment consisted of 4 treatments of purple sweet potato compost 25 (B) g, 50 g (C), 75 g (D), 150 g (E), and 1 control (A), and was repeated 5 times. The data analysis technique used analysis of variance (ANOVA). Parameters observed were the number of leaves, plant height, leaf width, plant wet weight, plant dry weight, and root length. The results showed that the application of purple sweet potato compost affected increasing the growth and production of pakchoi. The right treatment in increasing the growth of pakchoi is treatment 150 g or treatment E. Treatment 150 g (E) can increase the number of leaves (13.13), plant height (16.32 cm), leaf width (4.88 cm), wet weight (16.60 g), dry weight (6.35 g), and root length (15.80 cm).
Dekomposisi bangkai terjadi segera setelah organisme mati mulai dari dekomposisi tingkat jaringan hingga tingkat molekuler. Laju dekomposisi bangkai hewan yang dikubur dipengaruhi oleh tiga faktor yaitu faktor fisik, kimia, dan biologi dari media yang digunakan mengubur bangkai. Faktor fisik berupa struktur, porositas, dan kelembaban dari media. Faktor kimia berupa pH, konsentrasi natrium, nutrien, dan oksigen yang terkandung pada media penguburan. Faktor biologi berupa jumlah dan komposisi dari koloni bakteri, invertebrata, dan flora yang hidup pada media. Tujuan dari penelitian ini adalah untuk mengetahui apakah terjadi perbedaan kecepatan dekomposisi bangkai pada media penguburan yang berbeda. Penelitian ini dilakukan dengan menggunakan bangkai mencit sebanyak 36 ekor yang dikuburkan pada tiga media berbeda yaitu tanah humus, pasir pantai, dan tanah kapur di dalam toples plastik. Masing-masing sebanyak 12 toples diisi dengan media yang sama sebagai ulangan. Bangkai mencit diamati selama 28 hari dimana tiap tujuh hari dilakukan penimbangan terhadap berat bangkai mencit dengan timbangan digital dan kondisi fisik dari bangkai mencit dicatat dan diskoring. Laju dekomposisi bangkai mencit ditunjukkan dari perbedaan rata-rata penurunan berat bangkai mencit (%) tiap minggu pada masing-masing media. Metode analisis data dilakukan dengan uji ANOVA. Hasil dari penelitian didapatkan adanya perbedaan penurunan berat dan nilai skor kondisi fisik bangkai mencit pada tiap media penguburan. Kesimpulan penelitian ini adalah waktu dan perbedaan media penguburan berpengaruh pada penurunan berat dan nilai skoring kondisi fisik bangkai mencit.
