Rice consumption contributes the largest spending among Indonesian. Meanwhile, the changing price of rice is influenced by national inflation. Increased in rice consumption is caused by the increase of population. It is, therefore, clear that the problem of the rice price increament relates to rice demand and supply. This research was aimed to analize (1) factors influenced the demand and supply of rice in Indonesia; (2) effectivity of government floor price purchasing policy (GFPPP) vis-à-vis brown rice price policy in frame of increasing rice production; (3) impact of GFPPP on rice demand and supply in Indonesia. The research used time series data ranging from the year of 1981 to 2005. Two stages least square (2SLS) method was used to analyze the data by means of SAS/ETS Version 6.12. It is concluded that the GFPPP increased rice supply in Indonesia. The GFPPP also increased rice price at farmer level and rice production, but decreased demand of the brown rice. Keywords: rice, supply demand, policy of base price purchasing of government

The research objective was to study tree's vegetation structure based on diameter class distribution on varians vegetation types at Salak Mountain. Samples were taken at north, south, east, and west facing slope of Salak Mountain using line transect. Systematic sampling with random start was used to locate the transetcs. Measuring stem diameter at breast height was done in order to study the tree diameter class distribution. Non parametric U Man Whitney statistic was used to know whether there was a different in number of individual at all diameter class in each vegetation type. At mix forest and plantation forest, the tree diameter class distribution forming J curve shape. At bamboo forest, the individual number increase at the highest class diameter. The number of individual trees were highest at mix forest and lowest at bamboo forest. Key words: Mount Salak, Reverse J Curve, tree diameter class, vegetation type

The objective of this research is to formulate a specific model of Citarum’s watershed and its coastal management policy. The method applied in the research is the descriptive method or retrospective through a study case with an approach system. The multidimensional systematic approach is applied to formulate policies, to develop scenario strategies involving several stakeholders and experts on coastal areas and regional and inter sectors. The results of the research determine that the economical value relating with the aspects of pollution which in general involves replacement costs indicate impacts of pollution from public activities in the coastal stream in de facto costs Rp 31 billion/year. The Index Value of a Sustainable Watershed and Coastal Management System (IkB-SIPPDAS) applied in the study area according to a multidimensional Rap-SIPPDAS method for upland, center and downstream area of the Citarum’s Watershed are 38.23; 38.27; and 33.59 respectively in a sustainability scale of 0-100, showing a non-sustainable status. The analysis result for every dimension of development management indicates that the economical dimension for the upland, middle and coastal part of the Citarum Watershed contains the highest index rate, which amounts up to 88.29. The index value is categorized ”good” or sustainable with the lowest value in ecology. The results of the statistics indicates that the Rap-SIPPDAS method is effective enough for application as a method to evaluate the Watershed and Coastal Management System in a specific river stream or a rapid appraisal area. The selected ideal design of the three scenarios for the watershed management policy and West Java’s Citarum coastal area is the progressive-optimistic scenario stressing the possible future condition to receive maximum support or in other words the scenario is based on the scientific way of thinking and being optimistic about the future. Key words: watershed, coastal, scenario, system, management, pollutant, policy

Through a nutritional improvement project, Bogor District had donated powdered milk formula (PMF) for severe malnutrition children under five years. Powdered milk formula was assumed as an unsterilized product, because it might contain spore forming bacteria. To evaluate the bacterial contaminant of home prepared milk formula, fourty eight samples of PMF, and 50 samples of reconstitution formula, drinking water, drinking equipment, and hand were taken proporsionally from the mothers in 10 Health Community Centre around Bogor District. Samples were analyzed for aerobic microbe, Bacillus cereus, Clostridium perfringens, and the potential of enterotoxins production. All of the donated PMF samples exhibiting a total aerobic count of <104 CFU/g (mean 1.2 x 102 CFU/g) and B. cereus count of <103 CFU/g (mean 3.0 x 102 CFU/g for PMF containing this bacterium). Improper home storage promote the growth of aerobic microbe and B. cereus. Improper preparation promote the growth of B. cereus which present initially at low level (mean 7.8 x 10 CFU/g) and became 1.6 x 103 CFU/ml after the reconstitution. Clostridium perfringens emerge at 4 samples (mean 1.5 x 10 CFU/ml) after the reconstitution. Several isolate of B. cereus (4 from PMF, 13 from opened PMF, and 2 from reconstution formula) showed a possibility to produce diarrheagenic enterotoxin while the isolate of C. perfringens did not shown it. Keywords: powdered milk formula, B. cereus, C. perfringens, diarrheagenic enterotoxin, preparation and storage

The Effect of Phosphorus Fertilization and Variety on The Growth and Production of Soybean (Glycine m a (L.) Merr) Under Saturated Soil Culture
Get PDFThe objective of this expaiment was to study the effect of phosphorus fertilization on the growth and production of Americana and Lokon under saturated soil culture. The experiment was conducted at the Cikarawang Experimental Station, IPB, on a Latosol, from November 1988 until April 1989. Soybean yield did not respond to the phosphorus application, and maybe due to improved soil P availability under saturated condition. Leaf P concentrations at 9 weeks were sufficient (0.303 to 0.357%) for all levels of treatment. Active nodule growth was longer under saturated soil culture than conventional irrigation. Maximum active nodule growth under conventional culture was reached at 6 weeks, but under saturated soil culture was still increasing between 6 to 9 weeks from 0.175 to 0.342 g/plant for Americana and from 0.162 to 0.260 g/plant for Lokon. Increase of active nodule dry weight was followed by increase of leaf N concentration between 6 to 9 weeks from 3.366 to 3.674% for Americana, and from 3.382 to 3.695% for Lokon. Americana was more tolerant than Lokon to saturated soil culture. Number of Tied pods, 100- sads weight, and seed dry weight/plot of Americana were bigger than Lokon

Efektivitas Agronomik Fosfat Alam Diasamkan dengan Asam Sulfat dengan Berbagai Ukuran Butir Pada Tanah-Tanah Masam
Get PDFDari tahun ke tahun, kebutuhan pupuk untuk produksi pertanian terus meningkat tidak terkecuali pupuk P. Pupuk P dalam bentuk TSP sudah diproduksi di Indonesia namunsebagian besar bahan baku pembuatan pupuk tersebut masih hams diimpor. Akibatnya harga pupuk P dirasa semakin mahal apalagi jika tanpa subsidi pemerintah. Oleh karena itu penggunaan fosfat alam sebagai salah satu alternatif usaha efisiensi pupuk fosfat tampaknya patut dipelajari lebih lanjut.Salah satu cara meningkatkan efektivitas fosfat alam sebagai pupuk dengan cara meningkatkan sifat kelarutan fosfat alam melalui pengasaman sebagian. Pengasarnan fosfat alam dilakukan dengan mencampur fosfat alam dengan asam baik dalam bentuk asam sulfat, fosfat maupun nitrat dalam jumlah kurang dari yang dibutuhkan untuk pembuatan superfosfat. Penggunaan asam sulfat sebagai bahan pengasam memberikan keuntungan dari segi harga asam yang relatif lebih murah serta perolehan tambahan unsur S dalamcampuran pupuk
