REMOVAL OF SEAWATER HARDNESS CONTAIN Ca2+ ION USING NATURAL ZEOLITE AS ADSORBTION

Indonesia was an archipelago country in which 2 / 3 was surrounded by the ocean. Sea water contains many minerals that was useful and there was also elements that harm human beings one of which is Ca2+ ions that cause water hardness. Ions can be removed by using natural zeolite as adsorbtion.This research was expected to utilize zeolite as an absorber to absorb Ca2+ ions contained in seawater causes of hardness so that it can be used and processed further and can be applied on an industrial scale.The method used in this research was batch research. Before the zeolite was used for adsorbent, zeolite first activated using NaOH 1N. Zeolite already active is mixed with seawater and then stirred. The conditions used in this research are the conditions specified amount of sea water, the weight of zeolite and stirring speed. While working conditions are the zeolite particle size and stirring time.Based on the results of research conducted, the best conditions obtained on the zeolite particle size of 100 meshes with 75 minutes of stirring time, producing levels of calcium (Ca2+) of 909.25 mg / liter

KINETIKA PEMBAKARAN BRIKET ARANG ENCENG GONDOK

To overcome the problem needs an alternative fuel that is then taken for processing combustion water hyacinth water hyacinth into charcoal briquettes. This research aims to study the reaction kinetics of combustion of charcoal briquettes on the basis of accelerated depreciation of water hyacinth water hyacinth charcoal briquettes with various varioabel temperature and time to obtain the constant burning. This research was done by adding a binary solution in the form of starch with a concentration of 20% on charcoal water hyacinth which has a particle size 40 mesh, weighing 30 grams, then pressed and dried. Once dried water hyacinth dirimbang Charcoal briquettes and burned at a temperature of 200 oC, 250 oC, 300 oC, 350 oC and 400 oC until reaching constant weight. The results obtained by the heating value of water hyacinth charcoal briquettes at 5673 cal / garm, 30.002% ash content with 0.0475 MPa compressive strength. Combustion reaction rate constant of water hyacinth briquettes obtained at temperature of 200 ° C is 0.1230, the temperature of 250 ° C is 0.1680, a temperature of 300 ° C is 0.2364, the temperature of 350 ° C is 0.3782, and the temperature of 400 ° C is 0.4804. Frequency factor (Ko) of 0.9401 / h and the activation energy of 4445.9125 cal / mol L Then it can be concluded in this study the reaction takes place on the order of one. Key words: accelerated depreciation of water hyacinth charcoal briquettes, rioabel temperature and time to obtain the constant burnin

Production Process of Liquid Fertilizer From Banana Trunk

Banana a plant that many grow in Indonesia. Utilization of banana mostly just takes the fruitand leaves, while the trunk of banana has not been much used. The existence of Ca, P and K in bananatrunk, then the banana trunk can be used as alternative raw material for the production of liquidfertilizer. Produce liquid fertilizer from banana trunk done with the extraction process using a processtemperature of 700C and stirring speed of 240 rpm. Results from the extraction process to analyzelevels of Ca, P and K. Where available Ca content: 16.2% weight, P content: 30.05% weight and Kcontent: 21.5% weight with volume 600 ml of solvent and 15 minutes of stirring time

Manfaat Ekologis dan Finansial Pemanfaatan Limbah Cair Agroindustri sebagai Bahan Baku dalam Produksi Biogas untuk Mereduksi Emisi Gas Rumah Kaca(ecological And Financial Benefits Of Agro-industrial Wastewater Utilization AS Raw Mater

Agroindustries in general produce a large amount of organic wastewater. Until now, most of this organics waste-stream was not recovered and left to decompose anaerobically in ponds, where it emits methane, a potent greenhouse gas. By anaerobically digesting of the effluents in a suitable bioreactor, methane can be captured and used for combustion in gas engines or boilers. This way, uncontrolled methane emission from the anaerobic decomposition can be avoided and the utilization of fossil fuels can be replaced partly with the renewable biogas from the decomposition process. In addition, the approach of reducing green house gas emission is potentially to earn financial incentive through Clean Development Mechanism project. This paper demonstrates quantitatively some potential ecological and economical benefits derived from utilising agroindustrial effluents by treating it anaerobically to generate biogas (with cases of cane sugar factory, starch industry, palm oil mill, and tofu industry) . As illustration, for each ton cane sugar produced app. 15 m3 methane can be emitted from uncontrolled anaerobic degradation of it wastewater. By capturing the gas and transforming it into renewable biogas, a methane emission of equivalent to ≈ 272 kg CO2 can be avoided and an energy value of app. 427 MJ with a money value of app. Rp 59 600,- can be obtained. In addition, a financial incentive of app. Rp 14 850,- is possible to be earned from clean development mechanism (CDM) project. The ecological and financial benefits derived from anaerobic treatment of agroindustrial wastewater as indicated by this study should therefore become the driving force for the implementation of the approach

Konsep Dasar Hukum sebagai Norma Sosial: Studi pada UU No 1 Tahun 1974 dan Kompilasi Hukum Islam

Tujuan dari penulisan makalah ini adalah untuk  mengetahui konsep dasar hukum sebagai norma sosial (studi pada UU No 1 tahun 1974 dan KHI). Focus kajian pada aspek nilai-nilai dasar hukum dan pada aspek penegakan hukum keluarga. Adapun yang menjadi alasan mengapa dua aspek tersebut perlu dikaji  karena  adanya fenomena unik dalam penerapan hukum keluarga yang belum bisa diterima seratus persen oleh masyarakat Indonesia tetapi eksistensinya masih dipertahankan oleh pemerintah. Metode yang digunakan dalam penulisan makalah ini adalah metode perpustakaan (library research). Makalah ini menghasilkan dua hal. Pertama, bahwa nilai-nilai dasar yang ada pada hukum keluarga di Indonesia adalah keadilan dan kemanfaatan. Kedua nilai tersebut saling menunjang. Namun kedua nilai dasar hukum tersebut belum menghasilkan ketertiban seratus persen dalam masyarakat.  Hal ini dikarenakan pilihan pemerintah dalam menggunakan metode Perumusan hukum dengan metode analisis normative sehingga  tidak bersifat otoriter dan tidak memiliki sasaran untuk mengharuskan  masyarakat untuk tunduk pada hukum keluarga secara paksa. Namun kekurangan metode ini dapat ditutupi dengan konten hukum yang berkemampuan untuk merubah masyarakat untuk mentransformasi diri tunduk pada hukum keluarga ketika sudah mendapatkan pemahaman yang tepat dan apabila mendapatkan permasalahan hukum. Kedua, Penegakan hukum keluarga Islam telah ditunjang oleh pranata hukum dan pranata sosial. Sebagian masyarakat telah mengunakan pranata tersebut dalam mendapatkan keadilan dan kemanfaatan, sehingga hukum keluarga dapat berfungsi sebagai institusi sosial yang melindungi masyarakat
