Judul: Analisis Jejak Karbon dan Air pada Produksi sayuran dengan Berbagai Sistem Pertanian (Studi Kasus di PT Kebun Sayur Segar Parung Bogor).
Abstrak: Production of vegetables comodity contributed to the total national GHG emissions (GHG) and water usage in agriculture sector. Agriculture activity and production activity in production of vegetables emitted GHG emissions naturally and also can affecting freshwater in nature. Because of that, this research was did to evaluate the environmental impact from production of vegetables with various farming systems by implemetation of LCA (Life Cycle Assessment). The impact was asessed consists of a carbon footprint assessment, total energy use, efficiency energy and water footprint. The results evaluation of the environmental impact on the production 1 kg product of red spinach, green spinach and kale with various farming systems show that estimated total GHG emissions is 1,104 kgCO2eq, total energy use is 2,276 MJ with value of Net Energy Ratio (NER) <1 and Net Energy Value (NEV) negative and total water footprint is 115 m3/Ha. Scenario optimization of usage materials and waste vegetables are expected reduce total GHG emissions, increase energy efficiency and reduce total water use in the production of red spinach, green spinach and kale with various framing system.

Judul: Analisis Strategi Penerapan Produksi Bersih pada Rantai Logistik Industri Hortikultura
Abstrak: Logistic chain of horticulture industry that supplies vegetables from farmers to the consumers generates wastes that pollute the environment. In 2009, the wastes value in Bogor was 13,3% of total wet market wastes which equivalent to 305 m3/day. The actors involved in logistic chain of horticulture commodity are farmers, middle man traders, packing houses, supermarkets, and wet markets. Cleaner production is a preventive method that can reduce the formation of vegetable wastes. The objectives of this research were to map the logistic chain of horticulture, to analyze the generated wastes and to select the cleaner production options that can be applied to minimize the generated wastes along the logistic chain. The methods that used in this research were quick scan of logistic chain flow and Analytical Hierarchy Process (AHP). The results showed that the percentage of added value at packing house were 36,96% for green spinach, 49,77% for water spinach, and 34,92% for chinese cabbage. The percentage of vegetable wastes that has been reduced by packing house were 1,8% for green spinach, 4% for water spinach and 3,5% for chinese cabbage. AHP was need to select the best strategic option among the five options, namely implementation of Good Agricultural Practices (GAP), demand-based production, implementation of packing house system, providing facilities and infrastructure for the implementation of cleaner production, and utilization of vegetable wastes for the economic products value. The result showed that packing house is the most important actor while the financial is the most important factor and implementation of Good Agricultural Practices (GAP) is the best strategy option for cleaner production implementation.

Judul: Asymptotic Distribution of Estimator for the Intensity Function of a Doubly Periodic Poisson Process
Abstrak: In this manuscript, estimation of the intensity function of a doubly periodic Poisson process is discussed. It is assumed that only a single realization of the Poisson process is observed in a bounded window [0,n]. It is also assumed that the period of the intensity function is known. The rate of consistency and asymptotic normality of the estimator are formulated. Finally, a confidence interval for the local intensity function is also formulated.
