The agricultural sector has an important role in developing economy as a contribution for the national Gross Domestic Product (GDP). Thus, it iimportant to see agricultural export related to agricultural GDP. Structural change caused by economic crisis is also important to be observed in terms of its influence toward variables in the agricultural sector. This research functions to: (1) Analyze short term and long term relations between agricultural export and GDP of the agricultural sector and other variables in Indonesia’s agricultural sector; (2) Analyze structural in Indonesia’s agricultural sector. The method used is ECM model and Chow Test. Agricultural GDP has a different relation towards agricultural export in short term and long term. Then, there was a structural change caused by economic crisis in 1997. Estimation result after added by monetary crisis dummy in 1997 shows that in short term, agricultural GDP one year previously, agricultural TFP, agricultural domestic price, agricultural export price, agricultural domestic price one year previously, and economic crisis dummy of 1997 have significant influences toward agricultural export. Analysis of the new ECM result (short term) showst that the parameter coefficient signs of the following variables: agricultural GDP, agricultural TFP, agricultural domestic price, agricultural export price, in accordance with the hypothesis are variables with a one year lag. There is a lag of agricultural export in response to the influencing variables.

Food loss occurs in urban area restaurants, including in Bogor. The consumption activity in restaurants sometimes produces food waste, including of rice, vegetables or side dishes. The research objectives were (1) To identify the restaurant food-wasting process in Bogor, and (2) To estimate the amount and economic value of restaurant food waste in Bogor. The Indonesian National Standard (SNI) 19-3964-1994 about Sampling and Measurement Method and Composition of Urban Waste was used for sampling. Food waste in restaurants occurs from sellers and customers. The unsold food waste of restaurants in Bogor was predominately rice. The occurrence of rice waste was due to large cooking portions and the drying of rice during cooking, making it unable to consume. The food waste produced from unconsumed food by customers included rice and side dishes, such as meat, chicken and fish. Some reasons for food waste occurrence from visitor consumption were unpreferred food taste, large food portion and low appetite. The annual rice waste from unsold and unconsumed food in restaurants in Bogor was 29,742.84 kg or Rp 356,914,080. The annual amounts of meat, chicken, and fish waste are 14,780kg, 28,500kg and 8,460 kg, respectively. The economic value of meat, chicken and fish waste is Rp 1,655,640,000, Rp 712,480,000 and Rp 253,711,500, respectively. Keywords: consumption, the Indonesian National Standard (SNI) 19-3964- 1994, urban waste, consumption chain, weight conversion factor

Ciletuh in Sukabumi area was inaugurated as a Global Geopark by UNESCO in 2017, and has many potential natural resources such as Palangpang Beach as a leading tourism area of Ciletuh Geopark. Palangpang Beach in Ciletuh Bay is also an estuary area used by fishermen to collect fish in Fish Auction (TPI). Fishermen on Palangpang Beach are categorized as small fishermen according to the size of the capture fishery units, which results in the fishermen on Palangpang Beach prefer to take part in tourist activities by chartering boats for tourists to increase their income. The objectives of the study were to investigate the impact of Geopark establishment on fishermen's livelihood and to establish ecotourism development strategies in supporting the sustainable livelihood. The method used for sustainable livelihood analysis was descriptive analysis. The results showed that increased sustainable livelihood assets of fishermen were found in human capital, social capital, physical capital, and economic and financial capital, while natural capital assets declined. The Geopark Ciletuh development strategy to improve the sustainable livelihood can be performed through the fishermen involvement in capture fishery and Geopark tourism management such as by becoming a tour guide, a fishing trainer, an educator who educates on fishing weather in fisheries, a mangrove planter, and a coral reef educator.

Nowdays, increasing in food availability is not only focused on increasing production, but also by reducing losses at the production and distribution stages (food loss). The purpose of this study is: estimating the volume and value of food loss of rice commodities at the stage of harvesting, threshing, drying, milling, and distribution of rice in Karawang Regency. The research method used are quantitative analysis and qualitative description analysis, by using the method of calculating food loss. Based on research, rice loss occurs in every process starting from harvesting, threshing, drying, grinding and distribution in Karawang Regency. The greatest loss of rice in Karawang Regency occurred at the stage of milling. Estimated value of rice loss in Karawang Regency is around Rp. 321 billion/year. The size of the loss of rice in Karawang Regency locations indicates the need for various efforts to reduce these losses.
