Abstract

Kiln is an equipment which has vital existence in the manufacture of cement. Kiln firing requires a hightemperature to produce a clinker. Higher combustion temperature allows heat transfer occurs on the surfacecoating on the walls of the kiln that is not evenly distributed, so most of the heat is absorbed. As a consequence,it requires large amounts of fuel. Heat efficiency in the kiln is important to know. Production of clinker in thekiln which occurs at high temperatures, will also release a variety of gases, such as CO2. Carbon dioxide isincluded as one of the greenhouse gas, this gas will negatively impact the earth's ozone. Therefore, need to knowthe range of greenhouse gas that is formed, in order to determine the appropriate mitigation and prevention.Evaluation result of heat efficiency in the kiln is 43,17% by generating greenhouse gas emissions amounted to6,173 tonnes CO2 equivalent / tonne of coal.

Abstract

Upaya pengelolaan lingkungan terus dilakukan oleh berbagai pihak termasuk PT. Phapros yang merupakan salah satu industri yang bergerak di bidang farmasi. Penelitian ini dilakukan sebagai upaya pemanfaatan effluent dari IPAL PT. Phapros yang sudah memenuhi baku mutu untuk industri farmasi agar tidak dibuang begitu saja ke badan air. Salah satu upaya pengolahan yang dapat dilakukan adalah dengan  Sistem  Lahan Basah Buatan Aliran Bawah Permukaan (SSF-Wetland). Tanaman yang digunakan dalam penelitian ini adalah Cyperus alternifolius   dan Canna indica, L. dengan menggunakan dua media tanam yang berbeda yaitu pasir dan kerikil. Parameter kualitas air yang diukur adalah BOD, COD, ammonia, dan nitrit. Jumlah reaktor SSF- wetland yang digunakan sebanyak empat buah yaitu masing-masing berisi tanaman Cyperus alternifolius dengan media pasir, tanaman Cyperus alternifolius dengan media kerikil, tanaman Canna indica, L. dengan media pasir, dan tanaman Canna indica, L. dengan media kerikil. Aklimatisasi tanaman dilaksanakan selama tujuh hari dan pelaksanaan penelitian SSF  -wetland selama 15 hari. Pengujian parameter kualitas air dilaksanakan selama dua hari sekali. Hasilnya menunjukkan bahwa reaktor dengan tanaman Cyperus alternifolius media kerikil lebih efektif dalam menurunkan parameter BOD, COD, nitrit, dan ammonia dalam penerapan SSF-wetland dibanding dengan ketiga reaktor lainnya. Reaktor SSF-wetland dengan Cyperus alternifolius media kerikil memiliki efisiensi penurunan BOD 98,9 %, COD  sebesar 9,58 %, ammonia  sebesar 86 %, dan nitrit  sebesar 97,23%.  Kata kunci: SSF-Wetland, Cyperus alternifolius, Canna indica, L., effluent IPAL, industri farmasi

Abstract

Abstract At integrated farming areas Bangka Botanical Garden Pangkalpinang treating some of solid waste mixed with biogas digester will be used as fuel gas stove. Existing conditions in the dairy cattle by using the solid waste with 132 kg / day means at least they still used solid waste of 5 cows, so the biogas produced only 1 m3 / day. This paper is studyng about the energy’s need, economic and environments aspec in solid waste treatment to biogas and also about biogas management to provides the electricity need in the BBG Farm. The study is descriptive. The data have been taken from observation, measurement and interview with the farmer as the informan. Biogas produced can be used as lighting 60-100 watts for 50 hours, the driving source of energy 1 PK for 17 hours, producing 39 kWh electric energy and be able to cook 3 dishes for 40-48 servings. To produce 39.48 kWh / day, it can be used as a source of electrical energy BBG farm that has 35 lights with 25 watts of power which is lit for 12 hours / day. Up for lighting requires 10 kWh / day. For milking machine with 0.55 watts power usage requires 1.1 watts 2 times the rest can be used as a motor to move the water pump, lawn mower and activity classification. The BBG Farm need to increase the efficiency of utilization of biogas digester or biodigester everaging 1 unit abandoned and improve lighting installation connection using biogas. Keywords: biogas,cattle, energy,potential.

Abstract

Microbial Fuel Cells (MFCs) adalah bioreaktor yang mengubah energi kimia dari senyawaorganik menjadi energi listrik melalui reaksi katalitik mikroorganisme dalam kondisi anaerob. Tujuandari penelitian ini adalah mengetahui pengaruh variasi media terlekat (attached growth media) danvariasi konsentrasi COD awal terhadap efisiensi penyisihan konsentrasi COD dan energi listrik yangdihasilkan. Reaktor MFCs didesain dalam bentuk dual-chamber yang dihubungkan menggunakanjembatan garam. Kerikil dan bioball digunakan sebagi variasi media lekat pada kompartemen anodadan konsentrasi limbah awal divariasikan dari 0%, 25%, 50%, dan 100% dari konsentrasi COD limbahcair industri tahu asli dengan cara melakukan pengenceran.Hasil penelitian menunjukkan bahwamedia lekat kerikil dengan konsentrasi 50% menghasilkan arus listrik rata-rata tertinggi 7,25 µA danenergi listrik sebesar 179,54 mWh. Voltase dan enegi listrik pada kedua variasi tersebut semakin harisemakin menurun. Variasi konsentrasi 25%, 50%, dan 100% menghasilkan penurunan nilai effisiensipenyisihan COD masing-masing 41,41%; 39,90% dan 18,26%.Pada variasi 100% menghasilkanenergi listrik lebih rendah dari pada 50%. Kemungkinan hal ini karena adanya senyawa sulfida yangberperan sebagai akseptor elektron. Pembentukan senyawa sulfida ditandai dengan terbentuknyawarna hitam pada substrat. Efisiensi coulombic (εC) akibat perbedaan media lekat dan variasikonsentrasi berada pada kisaran 0,001-0,035%. Rendahnya εC kemungkinan karena adanya produkproduk fermentasi dan biofilm pada elektroda anoda yang menghambat transfer elektron menujuelektroda anoda seperti biomassa, bahan organik terlarut, gas H2 dan gas CH4

Abstract

This research are to know the correlation of the number of population with the amount of waste inMalang city and biogas potential at Supit Urang landfill. Then also counting the percentage of biogaswhich has been used as gas fuel by citizens around the landfill and as electrical energy potency. Theaverage amount of waste in Malang city is 410,45 ton per day. Organic waste composition at SupitUrang landfill is 64,9% or in the average it’s about 137.989,57 kg per day. From that amount, theaverage of biogas which is produced is 19.146,57 m3 per day or about 574.397,05 m3 per month.Biogas utilization is for fuel gas by 408 houses near the location of that landfill, that’s about 18.385,19m3 per month or about 3,2%. Therefore that’s still has 96,8% biogas potential or about 556.011,86 m3per month which has not been utilized yet. That potency can produce electrical energy 2.613.255,75kWh per month or 3,63 MW. If the average efficiency level of conversion from biogas to electricity is35%, the electric potential become 914.639,51 kWh per month or as big as power station with energy1,27 MW

Abstract

ABSTRACT: Developing graduate core competencies in higher education has been becoming an actual and trend issue due to the greatest concerns of students, governments, and employers about the quality of higher education outcomes. Higher education in Indonesia should turn the policies and the curriculum of university from conventional objective to recent contexts of global changes and employment settings. University must develop a curriculum which is not only aim to develop students’ knowledge but also to develop students’ core competencies, namely communication skill, IT (Information and Technology) skill, numeracy, learning how to learn, problem solving, working with others, and subject content competencies. The frameworks of core competencies development should be formulated and implemented and graduate “core competences” must become a measurement of quality to face the global competition. By this manner, intended outcomes of higher education namely employability, lifelong learning, and good citizenship will be attained. In other words, the universities in Indonesia should envisage that every single graduate of the university posses the seven attributes. The seven skills could be carried out in delivering course content. Finally, by equipping students with the core competencies they will succeed as professionals and responsible members of society. KEY WORDS: Core competencies, higher education in Indonesia, policies and curriculum of the university, and global competition. About the Author: Hadiyanto is a Lecturer at the Faculty of Teacher Training and Education UNJA (Universitas Negeri Jambi or State University of Jambi) in Sumatera, Indonesia.
