The growth of weeds among agricultural crops is a pest that can decrease agricultural production by 47-87%. The aims of this research is to compare organic and an organic fertilizer and compare mechanical and chemical weed and pest control. This research employed a mixed-method, observation, in-depth interviews, and life cycle assessment. The greenhouse gas emissions were released are organic fertilizer 1,87 x 10-3 kg CO2 eq/ha and an organic fertilizer 15 x 101 kg CO2 eq/ha. Thereafter greenhouse gas emissions were released from mechanical control 1,87 x 10-3 kg CO2 eq/ha and chemical control 4,4 x 101 kg CO2 eq/ha. The totally of greenhouse gas emissions was released from dryland paddy farming in management phase is 19,4 x 101 kg CO2 eq/ha. Organic fertilizer more friendly than an organic fertilizer and mechanical control more friendly than chemical control. Mechanical control by farmers must be modified for the increase of effectiveness. The post-mechanical control should be those containing fruit and seed must be burned, meaning there will be not a longer any weed growth potential. Therefore, this mechanism will be able to realize potential production and sustainable dryland paddy farming.

Java’s North Coast National Road also known as Jalur Pantura is a primary transportation corridor connecting Indonesian capital city of Jakarta and eastern part of Java Island. Interestingly, the road’s greenbelt is located in Karawang Regency planted with various trees. From its diameter breast height (DBH) and height, above ground biomass (ABG) from these trees were estimated and then compared with four vegetation indices namely NDVI, SAVI, EVI and tasseled cap extracted from SPOT-7 satellite image. Furthermore, this study used predicted ABG values to generate carbon stock and carbon absorption ability. In addition, data from daily vehicle traffic observation will be employed to predict carbon emission. Estimated vehicle carbon emission then compared with carbon absorption ability for each road segment to observe how big trees can store carbon emission from vehicle. The information of carbon balance in each road segment, in form of comparison between carbon absorption ability with vehicle carbon emission, can be useful for road authority to increase vegetation especially in the areas of low carbon absorption.

Tanjung Lesung Beach is a government priority to be developed because it entered the Special Economic Zone which was inaugurated on February 2015. This coastal area was chosen as a special economic zone because it has criteria as SEZ in accordance with Law Number 39 of 2009 concerning Special Economic Zones. However, currently, Tanjung Lesung Beach has experienced a decline in tourists due to the Sunda Strait tsunami on December 22, 2018. This study aims to analyze the right strategy to develop the Tanjung Lesung Beach tourist attraction to attract tourists and identify its contribution to the surrounding community. Based on the results of the tsunami research that befell Pandeglang District, it greatly affected the interest of tourists to visit and also resulted in some tourist facilities being paralyzed. After the classification of the feasibility of developing a tourist attraction with the ADO-ODTWA method can be concluded after the tsunami 73.1% Tanjung Lesung Beach is still feasible to develop and has high potential. In terms of the social and economic aspects of this tourist attraction, it contributes to society such as many surrounding communities who work as hotel employees in the region, build infrastructure, and build new businesses. Various new businesses began to emerge such as managing homestays, inn, villa tenants, boat rentals, culinary tours, crafts, arts.
