Production can be increased through improved harvest index genetic engineering, and the availability of nutrients in the soil. Ciherang rice production tests conducted over two years by toposekuen in Tabanan. First in five Subak, (Jangga, Bulung Daya, Andal Dewa, Lanyah1, and Perean) with 10 fertilizer treatments. The second year, five fertilization treatments in the two Subak (Petung dan Babahan). The study was conducted in randomized complete block design with three replications. Parameters observed included vegetative and generative growth, and yield of paddy field farming. Duncan`s test, with a confidence level of 5% using the Costat program, and input output fertilization. Fertilization is very significant effect on rice production. The first year results, the highest rice production (9.33 tons ha-1) was achieved in a combination of fertilizer treatment (organic + NPK + mineral), can increase production 43.98%. The second year of the highest rice production (11.878 tons ha-1) were achieved on the fertilization of NPM (100 kg urea + 100 kg Phonska ha-1) + organic fertilizer (2.5 tons ha-1) + mineral fertilizer (2.5 tons ha-1), production increased 50.4%. Organic fertilization received the lowest rice production (5,420 to 8,940 tons ha-1), and the highest percentage of empty grain (9.29%). Mineral fertilizers can reduce the use of chemical fertilizers and high-dose organic fertilizers. The increase in yield of paddy field farming compared to control for the treatment of organic fertilizer (Rp 1.011 million ha-1), NP (Rp 6.416 million ha-1), NPK (Rp7.636 million ha-1), and NPM (Rp12.576 million ha -1).

This study aims to identify and provide land suitability database of Subak to support sustainable agricultural development and provide spatial information such as land suitability maps with existing inhibiting factor. The method used was field survey to obtain data characteristics/quality of land through soil sampling on several land units sample, and soil analysis in the laboratory. Land suitability classification was done using the criteria from the Technical Instructions Evaluation of Land for Agricultural Commodities by matching between the quality/characteristics of the land with the growing requirements of rice crop being evaluated. The analysis of actual land suitability both of S2 (little suitable) with limiting factors included drainage, texture, depth of planting, salinity, N- available, P-available and K-available, and slope; and S3 (marginally suitable) with limiting factors such as N-available, P-available and salinity. The assumption of business improvements that can be made to the determine quality/characteristics of the land Subak was an inhibiting factor, with optimization by improved drainage channels, N and P in accordance with the needs of the rice plant. Therefore the suitability of potential land for irrigated rice crops can be mapped by GIS and can be increased to very suitable (S1) level. In conclusions, the actual land suitability was categories as 72% little suitable (S2) and 28% marginally suitable or S3 with inhibiting factors included rooting medium, availability of nutrients, slope and salinity. While the suitability of potential land consisted of all of Subak that invery suitable (S1)level, so that the existence of Subak in Denpasar should be protected.

Increased production of foodstuffs is required in line with increasing population. The tourism sector in Bali needs quality products that are both viable and environmentally friendly. Previous research since 2002-2016, found mineral fertilizer plus can increase the highest production, , increased soil quality, and increased farm income. The research location was in Baturiti Subdistrict. The plant tested was string bean (Phaseolus vulgaris L) during first planting and residual effect of first fertilization (second planting). Eight fertilizer treatments: P0=control, P1=organic, P2= mineral, P3=chemical (NPK), P4=combination ½ (organic+chemical), P5=combination ½ (mineral+chemical), P6= Baliplus mineral fertilizer (BMF) =combination ½ (organic+mineral+chemical), and P7=combination ½(organic+mineral)], three replications. Parameters observed were bean weight, storage capacity, and value of farm income. The experimental designed used was Randomized Block Design, with Duncan's real test difference of 5%, using the Costat program. Fertilization was very influential and significantly affected to the production of the first planting and residual effects. The treatment using BMF in the first crop,resulted in the highest production (34.33 tons ha-1), highest production increase (62.92%), longest storage (36%) for one week, and the highest farm income (Rp 334 million ha-1). The P1 treatment showed the lowest production (25 ton ha-1), the lowest increase (18.45%), storage capacity (15.27%), and the lowest farm income (Rp 28.7 million ha-1). String bean with the highest residual effect (16.17 ton ha-1) was obtained in treatment P4. The average production of the remaining effect is 48.62% of the first crop. The use of mineral fertilizers plus bali can increase production, savings, and farm income, and reduce 50% of the use of chemical and organic fertilizers.

AbstractActivities pertaining to development of spatial planningpolicy, its execution, its evaluation and review in spatialdevelopment at a national, provincial, and regencial level inIndonesia is first mandated by the Indonesian State RegulationNo. 24/1992. In line with the instigation the State LocalAutonomy Policy, this regulation has then been substituted bythe Indonesia State Regulation No. 26/2007 on Spatial Planning.For its implementation, this regulation is later completed withthe release of the Indonesian State Regulation No 26/2009.Conformance with these regulatory products as well as theIndonesian State Regulation No. 5/1960 on Land Reform, havegenerated problems, which are different to those of othercountries.Problems relating to spatial planning in Bali are morecomplex compared to those generally encountered by otherprovinces in Indonesia. As an illustration here is a list ofspatial predicaments that Bali has been faced with for the lastfour decades: dispute over land tittles situated in both socioculturallyand environmentally strategic zones; problemsrelating policy development; ambiguity in regard to the integrityof each regulatory product imposed on the society; provisionof financial requirements as well as provision of adequateexpertises required to bring policy into its implementation;development of spatial database system; conflicting interests inland development; economical aspects; socio cultural concerns;environmental protection; politics, demography; security andsafety. In terms of policy implementation, Bali has problems withpermit and public participation. And in term of control, Bali hasdifficulties in regard to the roles of each local government, thepublic and its various social groups.This paper emphasises that the problems stated above canbe approached using a local to national strategy. The proposedstrategy is to be excecuted by providing every community witha definitive framework, that is completed with a detailed policyattached to every single spatial zone exist at a village level.Govenrment at a district, regencial as well as provincial levelsare also equipped with detailed governing functions and rolesto ensure that they are fully informed and have the capacity toimplement the imposed spatial plan adequately. Within thisstrategy, the main controling position will be held by the public,medias, as well as other parties who have great commitmentsand concerns in protecting Bali’s natural environment, itsculture, and promoting growth and development activities thatconsciously embrace local wisdoms within the dynamic of theIndonesian State.

Subak in this paper is a unit of agricultural area, with names, have palemahan (paddy field resource), pawongan (human resources/farmers), and paddy field farming systems. Subak as local genious Bali, constructed since the 7th century, until now Subak system still exist in Denpasar. UNESCO, in 2011, rewarded Subak as a world cultural heritage. Ironically, not one district/city, and the Province of Bali has maps spatially Subak, they only have statistical data. The development era of technology and communications requires the ease and speed of getting data and the latest information with a high degree of spatial accuracy. The answer requires data base information based on information and communication technology (ICT). Worldview satellite imagery coverage of Denpasar in 2015, and ArcGIS 10.3 software used for mapping land and extensive rice fields of Subak (spatial data). Secondary data consists of land resources (LR), the primary data includes the name pekaseh delineation and area subak, human resources (HR) and agricultural activities were used as attribute data. Denpasar City has 41 Subak in 2015, Subak area on the analysis of satellite imagery (2008.6 ha) was smaller (520.4 ha) than the Central Statistics Agency (CSA, Denpasar 2529 ha), with r2 = 0.8967. Soil fertility moderate, land suitability agro-ecosystem very suitable (S1) for rice field and suitable (S2) for second crops and horticulture lowlands, required land cultivation and fertilization, suitable to crop needs. HR status of farmers as cultivators 72% and Landowners 28%.Subak paddy crop rotation pattern Denpasar City is paddy-paddy/palawija–palawija/paddy. The data base is composed of a map Subak Subak (spatial data), the data LR, HR and agricultural activities (attributes data).
