Abstract

Coffee is a commodity that has an important role in the national economy. Currently, coffee cultivation is threatened by climate change caused by global warming due to increased green house gas (GHG) emissions. The organic  plantation model is a farming model that is considered to increase soil and crop productivity, reduce GHG emissions, and increase carbon sequestration effectively. The study was aimed to estimate GHG emissions and carbon stocks in organic and conventional coffee plantations in Badung Regency, Bali Province and  Laboratory in Balai Penelitian Lingkungan Pertanian, Pati, Jawa Tengah Province, in July 2018. The study was conducted in smallholder coffee plantations in Badung Regency and the analysis was carried out at Laboratory of Indonesian Agricultural Environtment Research Institute. This study used a survey method, while the sampling used a purposive sampling method in organic and conventional coffee plantation. GHG emissions measurement was carried out with a close chamber method by simultaneously the carbon stocks measurement was carried out with the non-destructive method for plant biomass and destructive for understorey. The results showed that organic and conventional coffee plantations emitted GHG by 20.71 and 39.75 ton CO2e ha-1 and stored carbon stock by 227.56 and 288.31 ton CO2e  ha-1, respectively. The differences in GHG emissions and carbon stocks are partly due to differences in management system and the diversity of plant. The management system of the organic coffee plantation should be improved to support handling of the impacts of climate change in Bali Province.

Abstract

Upland rice commodity is generally the second choice after paddy in fulfilling community rice needs. Morotai Island is one of the government's target locations in initiating the Export-Oriented Food Storage program in the Border Region. This study aimed to determined the prospects for the development of upland rice to support food barns in the border region of Morotai Island. The method used is descriptive analysis, measuring the growth rate of rice based on the Compound Annual Growth Rate (CAGR), and measuring the feasibility of farming using income analysis, R/C ratio, and break-even point analysis. The results showed that the increase in the growth rate of harvested area and upland rice production was 25,75 percent with a contribution of 42,81 percent and 31,65 percent, recpectively, of the harvested area and rice production on Morotai Island in the 2011 to 2017 period. Upland rice farming has an R/C ratio of 1.72 which indicated that this farming is feasible. The potential and opportunities for upland rice development to support food barns on Morotai Island are still very prospective. The development of upland rice can be pursued through intensification and extensification of agriculture with the application of cultivation technology, the use of new high yield varieties, increasing the cropping index, and sustainable soil and water conservation efforts. This needs to be supported by strong farmer and extention institutions and easy access for farmers to finance agriculture.

Abstract

Budidaya tanaman padi memegang peranan penting dalam peningkatkan produksi pangan di Indonesia dan pembentukan emisi CH4 dari lahan sawah. Pemberian bahan organik ke dalam tanah berfungsi untuk memperbaiki kualitas tanah dan meningkatkan produktivitas tanaman, disisi lain dapat menyebabkan emisi gas rumah kaca. Besaran emisi CH4 akibat pemberian bahan organik tergantung pada kandungan C organik dan tingkat dekomposisinya. Pemilihan bahan organik yang tepat perlu dilakukan sebagai upaya untuk mengurangi emisi CH4 tanpa mengabaikan produktivitas tanah dan tanaman. Penelitian ini bertujuan untuk menentukan bahan organik yang dapat meningkatkan produktivitas sekaligus menekan emisi CH4 dari budidaya tanaman padi di lahan sawah tadah hujan. Penelitian ini dilaksanakan pada bulan Oktober 2016-Januari 2017 di Kebun Percobaan Balai Penelitian Lingkungan Pertanian, yang merupakan salah satu daerah tadah hujan di Kabupaten Pati, Provinsi Jawa Tengah. Penelitian disusun secara acak kelompok dengan 4 perlakuan yang diulang sebanyak 3 kali. Varietas padi yang digunakan dalam penelitian ini adalah Ciherang. Perlakuan terdiri dari : 1) kompos 5 ton/ha, 2) jerami padi 5 ton/ha, 3) biokompos 5 ton/ha, dan 4) tanpa bahan organik. Hasil penelitian menunjukkan bahwa produksi padi yang dihasilkan oleh empat perlakuan secara berturut-turut adalah 4,76; 5,13; 4,72 dan 4,61 ton/ha dengan total emisi CH4 153; 281; 197; 143 kg/ha/musim, sedangkan nilai produksi padi per kg CH4 yang dihasilkan secara berturut-turut adalah 31,1; 18,3; 24,0 dan 32,2. Pemberian bahan organik berupa kompos berpotensi lebih optimal dalam meningkatkan produksi padi dan menurunkan emisi CH4 di lahan sawah tadah hujan dibandingkan jerami padi dan biokompos.
