Basically a person's consumption behavior is more influenced by his perspective on the meaning and purpose of consuming an item. So that some people are more displeased (hedonism) or just to fulfill their own needs (rationalism) caused by fanatics about the image of an item without considering the aspects of public interest (maslahah) and public harm (mafsadah). These patterns continue to be instilled in society imperialistically which eventually becomes a value, structure, social and lifestyle in community. In the Islamic concept, consumption behavior as a unity between worship and devotion is inseparable from the concept of tauhid (theocentrism). Inconsumption a Muslim must take attention to the social and economic aspects of other people. It means not only fulfilling his own needs but maqasyid sharia as a benchmark in consumption. This article tries to reconstruct the concept of Western consumption behavior which brings a lot of mafsadah and harm to society with an Islamic worldview prespective. Keywords: Consumption, Islamic Worldview, Maqashid Syari’ah

Telah dilakukan penelitian dekolorisasi Direct Black 38 menggunakan kitosan dari limbah udang Delta Mahakam. Penelitian dilakukan untuk mendapatkan kondisi optimum proses dan kapasitas adsorpsi kitosan. Variabel yang digunakan dalam penelitian ini yaitu: waktu (20-480 menit), massa kitosan (0.01, 0.1, 0.5, 0.75, 1, 1.5, 1.75, 2 gram), dan konsentrasi Direct Black 38 (2, 5, 10, 50, 100 ppm). Direct Black 38 dengan konsentrasi awal 500 ppm diencerkan menjadi 100 ppm. Sampel sebanyak 100 mL dimasukkan dalam erlenmeyer dan ditambahkan sejumlah kitosan. Sampel diaduk menggunakan shaker dengan kecepatan tertentu hingga tercapai kesetimbangan. Sampel disaring dengan Whatman 40 kemudian dianalisis penurunan konsentrasi Direct Black 38 menggunakan UV-Vis pada panjang gelombang 505.7 nm. Untuk mendapatkan data kapasitas adsorpsi kitosan digunakan model isoterm Freundlich. Hasil penelitian menunjukkan bahwa kondisi optimum adsorpsi Direct Black 38 adalah waktu adsorpsi 360 menit dan massa kitosan 1.5 gram. Penurunan konsentrasi Direct Black 38 pada kondisi optimum mencapai 63.10%. Data kapasitas adsorpsi kitosan terbesar diperoleh sebesar 4.21 mg/g berdasarkan persamaan isoterm Freundlich. Kata kunci: adsorpsi, dekolorisasi, direct black 38, kitin, kitosan

Frozen shrimp activities of many companies in the Mahakam Delta region leaving the potential of shrimp waste that has not been maximally utilized. Application of appropriate technology capable to transforming shrimp waste into products of high economic value such as chitosan. Chitosan is produced through a sequence of processes, namely the extraction of chitin and deacetylation. In this research was review to deacetylation process as the function of temperature and concentration of alkali by measuring the degree of deacetylation. This research was used design of experiment of completely randomized design (CRD)-single factor. Chitin powder introduced into a reactor together with concentrated solution of alkali (50-80% w/w) on 1:20 ratio. The mixture was heated (80-120oC) with stirring. After that, the mixture was filtered and the solids neutralized and dried it. Degree of deacetylation of chitosan was analyzed using FTIR. The results showed that the optimum conditions of deacetylation process is achieved at a temperature of 100°C, alkali 70% (w/v) and a ratio 1:20 (w/v) with the degree of deacetylation 80.59%. Chitosan analysis with the parameters of ash content, moisture, and viscosity were found to be 0.01%, 6.99% and 3.6 cP, respectively. The chitosan product is suitable for industrial applications.
