Abstract

Food shelf life can be determined by the critical factors that are most rapidly deteriorated. It can be evaluated by using Arrhenius method. This study aimed to determine the basis used by a company in evaluating the shelf life of food products. Observations were carried out on processed beef products sold in supermarkets in Bogor. Samples studied were meatballs, sausage, and beef burgers purchased from supermarkets under various trademarks. The calculation of shelf life was mathematically carried out by Arrhenius method that was through the measurement of the rate of quality parameter degradation. The results showed that Arrhenius model could be used to measure the rate of quality reduction of meatballs, sausage, and burger meat products so it could be predicted the shelf life of the product. The assumption used by the producers was quite appropriate because it was in accordance with the Arrhenius method.

Abstract

The development of new residential areas using independent city concept encourages the potential increase of greenhouse gas emissions. It is derived from new infrastructure development and residents activities in this area. The objective of this study was to estimate the amount of greenhouse gas emissions through carbon footprint calculations derived from the resident's activities in Gading Serpong, Tangerang. Carbon footprint values were conducted by questionaire from 200 respondents and from three different types of housing: clusters, sectors and general houses in villages around the area. The emission sources were calculated including transportation, energy use at home, food consumption, and lifestyle. The results showed that lifestyle gave the highest value contribution about 39% of total carbon footprint, followed by transportation and energy use at home around 30% and 27%, respectively. The average value of individual carbon footprint approximately 7.99 tCO2 Eq./year. Moreover, carbon footprint values for cluster-type, sectors-type and general houses in the village were 9,602, 8,453 and 5,009 tCO2 Eq./year respectively. The result also found that the resident's income has a significant contribution to carbon footprint value.This study showed that the carbon footprint value of residents in Gading Serpong area influenced by housing type and individual income level.

Abstract

Jakarta is a fascinating location for both artists and art curators. This paper attempts to show how the city serves as a cultural open stage where ordinary dreams unfold through the practices of contemporary art in the daily lives of citizens. Utilizing the philosophical inquiries of Michel De Certeau, on the relation between ?Space? and ?Place?, a qualitative study was conducted based upon data about Jakarta?s expansion, in terms of its urban physical structure and demographics; data analysis was also carried out on the contemporary art present in the daily life of the city. Through a phenomenological experience of and investigation into the artistic phenomena in Jakarta, three conclusions have been drawn: (1) Jakarta is a city of collaboration with local marginalized communities, (2) Jakarta is responding to its urban landscape and (3) Jakarta unwittingly has become the host of an alternative space in one of its ordinary traditional markets.

Abstract

Indonesia terus mengalami peningkatan jumlah penduduk terutama dalam satu dekade terakhir. Hasil proyeksi Badan Pusat Statistik (BPS) menunjukkan bahwa jumlah penduduk Indonesia pada tahun 2020 akan mencapai 271,1 juta jiwa dan akan terus meningkat hingga 15 tahun mendatang (Bappenas et. al., 2013). Seiring dengan meningkatnya jumlah penduduk, permintaan pasar pada sektor pangan juga akan semakin meningkat (Roidah, 2014). Namun, hal tersebut tidak diikuti dengan ketersediaan lahan pertanian yang cukup. Penurunan luas lahan pertanian terutama pada sawah mencapai 0,25% pada tahun 2013 (Pusat Data dan Sistem Informasi Pertanian, 2014). Keadaan ini yang menjadi landasan bahwa teknologi bercocok tanam dengan sistem hidroponik dapat diterapkan dalam masyarakat dan diharapkan dapat meningkatkan produksi bahan pangan terutama komoditas sayur-sayuran
