Farmers  in  the  paddy  field  farming  faces  some  fundamental  problems caused  by  the  narrower  tenure  due  to  increased  population  and  land  inheritance, creation of breakthrough technologies to increase the productivity of rice farming and farmers' income increasingly difficult for farmers to diversify motives are often more oriented to the  income  stabilization.  West  Java  is better known as the rice granary, is also a center of vegetables in Indonesia. Vegetable farming has been fused with the local community, especially for upland farmers. The last few years this development not  only  in  vegetable  crops  in  the  highlands  but  try also  try  in the  lowlands  in  the paddy field. Along with the above conditions, the policy support necessary to achieve the expected results. One obstacle in the application of vegetable farming is the lack of use of the means of production as a result of lack of financial ownership of farm households. The purpose of research is (a) reveals variability of farm crops especially <br />vegetables Onion, Long Beans, cauliflower and cucumbers. (b). And to evaluate the extent  to  which  government  policy  support  for  horticultural  commodities  especially vegetables in West Java. The research was  conducted in two districts of Indramayu (Chilli Red, Red Onion and Cauliflower), Falkirk (cucumber and bean length) of West <br />Java  Province. , Amounted to a total of 50 respondents drawn farmers. The results showed that farm incomes various vegetables (horticulture) is higher than the income of rice farming, especially in the red pepper (673%), onions (415%), while the rate of return  based  on  a  variety  of  vegetable  farming  is  higher  than  the  benefits  of  rice farming, especially red pepper (776%), onions (279%) cauliflower (200%) and beans (144%).

Swamp land has a great potential to be developed as a paddy field area. However it has many constraints such as-phyrite (FeS2) at the depth of 30–60 cm and lack of soil nutrition. On the other hand, supply of marine clay from the sea which contains a lot of smektit clay mineral can be used to netralize this condition. Mud clay is very important for the development of rice root because it contains much nutrition and to enlarge the top of soil reducing the oxidation of phyrite. This study was conducted from January 2016 to June 2017 in swamp land area of Barito River of South Kalimantan. Data was collected by measuring the difference between maximum and minimum sea tide (tidal amplitude) and the deposition of mud clay. The results indicated that the distribution of mud clay deposit vary depends on the geography and the tidal amplitude of the zone. Zone VII has higher concenration of mud clay than the other one. The distribution pattern of mud clay deposit follows the parabola type, verticaly and horizontaly type, as well. Increasing of mud clay at all of the zone areas are not significantly effected by the daily tidal amplitude, only depends on climate condition/the season change.

Pertamina Hulu Energi - Offshore North West Java (PHE -ONWJ) field has been operating for more than 45 years, located in offshore north of West Java Island with an area of 8,300 km2. Traffic around PHE-ONWJ field has increased significantly compared to the initial stage. It is important to note that ONWJ field area is close to Jakarta. As the level of activity increases, risks to all PHE-ONWJ subsea pipelines increase as well. One of the threats that arise is pipeline dent due to third party activity such as anchor drop/drag from vessels/ships sailing across subsea pipeline. An example is the 14” MOL EPRO – NGLJ pipeline which was built in 1983 (has been operating for 38 years). On September 4, 2008, an Inline Inspection campaign was conducted to check pipeline integrity. Before launching the MFL pig, a calliper pig was deployed to check the pipeline geometry for a safe minimum passage for MFL tool run. Unfortunately, after calliper data was downloaded, an 18.2% geometry anomaly was found (ID pipe=10.63 in) categorized as the highest dent at a log distance of 14,282 m from EPRO which did not allow the MFL to run. Due to age, geometrical and operating fluid conditions, the Company was urged to obtain more comprehensive data of the pipeline’s remaining wall despite the dent. Therefore in 2018, ONWJ engaged 3P to utilize their MFL tool capable of adjusting pipeline’s dent. After several tests such as pull through on an artificial dented spool had been successfully done, finally the tool was sent to Indonesia and was successfully run through the dent pipeline 14in MOL EPRO-NGLJ safely.

In 1998 to 2001, a commercial rice (Oryza sativa) paddy field (area: ca. 0.14 ha) was surveyed for Rhizoctonia oryzae and R. oryzae-sativae, causal agents of bordered sheath spot and brown sclerotium disease of rice plants, respectively, to determine their survival in soil and stubble during the pretransplanting season, and the effect on disease development during the maturation season of rice. Then, infection by these fungi of weeds belonging to 17 families, which grew in the four neighboring fields, was examined during rice growing seasons. All field isolates of the fungi from soil, stubble, rice sclerotial disease lesions (diseased tissues), and weeds were assorted into mycelial compatibility groups (MCGs) based on the barrage zone reaction of paired isolates. In R. oryzae, 3 to 8 MCGs were annually found from soil/stubble, 2 to 4 MCGs from rice bordered sheath spot lesions, and 4 to 9 MCGs from 4 to 14 weeds. MCGs common to both soil/stubble and diseased tissues, soil/stubble and weeds, and diseased tissues and weeds numbered 1 to 2 in all cases. In R. oryzae-sativae, MCGs common to both soil/stubble and brown sclerotium disease lesions, and soil/stubble and weeds, numbered 1 to 4 and 0 to 5, respectively. In R. oryzae and R. oryzae-sativae, a few MCGs were common to soil/stubble, diseased tissues and weeds, and some were also common to diseased tissues in 1998 and soil/stubble in 1999, or weed in 1998 and diseased tissues in 1999. Members belonging to a single MCG from rice diseased tissues were detected from maximally five weeds growing in the neighboring fields. These results indicate that fungi that had caused sclerotial diseases at the maturation stage of rice plants survived on and in soil and stubble until the pretransplanting season of the next year, followed by wide dispersal in and out of fields and by infection and disease development on rice plants and various weeds.

Population growth, increasing income, and the rapid economic development create complexity of land issues. Land has a central role in  food production, however demand for land increased significantly to meet the needs of the population. Cianjur Regency is one of regencies in the southern part of West Java Province with the largest paddy field area. However, paddy field conversion into non agricultural land or another agricultural land resulted in the decrease of paddy field area. Therefore, in the context of maintaining the availability of rice in Cianjur Regency, this study aimed to: (1) analyze the patterns of land use/land cover, (2) evaluate land suitability for paddy field, and (3) analyze the potency of land for paddy field expansion. Land use change was identified using Landsat imagery of 2000 and 2015 by using fusion techniques. Land suitability for paddy field was analyzed using limiting factor method. Potential for paddy field expansion was analyzed according to land suitability and agricultural land allocation in official regional land use plan map (“RTRW”). The results showed that in the period of 2000 to 2015, most of paddy field were converted into settlements. Land suitability classes for paddy field in Cianjur Regency were not suitable (N) (61.19%), suitable (S2) (9.53%), and marginally suitable (S3)(29.28%). Cianjur Regency still has the potency of land to be used for paddy field expansion of 148,980 ha. Keywords: Land use change, potential area for paddy field priority, land suitability for paddy field
