Abstract

Low levels of clean water supply in the Tanjung Tengah village causing the high price of water. value of Fe and TDS in the village raw water is high. The value of Fe content is 388 mg/L and TDS value is 12930 mg / L. The installation of salty peat water treatment technology were done to overcome this problem. The Salty peat water treatment technology consists of coagulation flocculation system, clarifier, filtration, reverse osmosis and a distribution systems. Results showed that this treatment efficiency reaches 99%. Where the iron content of the treated water is less than 0.003 mg / L, with a TDS value down to be 77 mg / L. The treated water also meet drinking water quality standards. Keywords : Clean Water, Salty Peat Water, Reverse Osmosis, Iron and TDS.

Abstract

Teknopark Pelalawan area is an area designed as a center for the development of local advantages generated through research. In the region there will be College of Technology Palalawan and various Research and Development Center as to the development of local products, industrial downstream palm oil products, forest products and small and medium scale industries. Means and supporting facilities such as clean water, waste water and drainage systems are currently being incorporated into the master document teknopark region Palalawan plants. Infiltration measurements conducted to support the planning of drainage systems in order to manage rainwater in the area of teknopark Palalawan. This measurement is done in both land area units, namely: dry land units and land units of wet peat. Infiltration measurements done using an instrument called a double ring infiltrometer. To measure the rate of infiltration were analyzed using Kostiokov method. The result is: infiltration in the drylands of 1.5 mm / min on a peaty wetland was 0.4 mm / min. The conclusion that can be drawn is that in order to manage the rainwater would be more efficiently carried out on dry land unit. Keywords: teknopark Pelalawan, infiltration rate, kostiakov, double ring infiltrometer, constant infiltration rate

Abstract

Office waste is produced from activity that carried in the office area. In Geostech office area, 18.05 % composition of the waste is plastic waste. Plastic waste total in Geostech is 17.1 kg/week. The highest of plastic waste type is PP (Polypropylene). plastic waste. From the waste total is known that that the potential of oil produced through pyrolysis is 11.6 kg/week or 13.7 L/week. Pirolysis oil can be used as substitute for diesel fuel because of the calorific value equal with the calorific value of diesel fuel. Besides oil, pirolysis of Geostech office plastic waste is also potential to give 5.45 kg/week gas product.Key words : waste, office, pirolysis, oil

Abstract

Sampah yang tidak dipilah dengan baik disumber akan memiliki komposisi sampah beragam dan tinggi kadar air. Kondisi ini menimbulkan permasalahan kesehatan baik bagi masyarakat yang tinggal dekat dengan pembuangan akhir maupun yang tidak. Sampah dengan criteria seperti ini, dapat diolah dengan teknologi hidrotermal. Teknologi hidrotermal memanfaatkan sifat air yang unik dan hanya berlangsung pada suhu dan tekanan yang tinggi. Hasil pengolahan sampah campuran dengan teknologi hidrotermal, menghasilkan produk yaitu bahan bakar padat. Bahan bakar padat ini memiliki nilai kalor yang setara dengan batubara batubara sub-bituminus grade rendah. Tantangan pengembangan teknologi hidrotermal untuk mengolah sampah datang dari segi pembiayaan, proses pengeringan produk, dan modeling pembakaran bahan bakar produk.  kata kunci : sampah, campuran, kadar air tinggi, hidrotermal, bahan bakar padat

Abstract

The low level of coral reef ecosystems in excellent condition in Bali waters shows the need for rehabilitation and restoration efforts on coral reefs. Crustose Coralline Algae (CCA) plays an essential role as a trigger for the attachment and metamorphosis of coral planules because it can produce chemical signals that the planula can perceive as instructions for attachment to the substrate. It is necessary to pay attention to the materials that make up the substrate. One of the substrate materials that can be used is ceramic. This research aims to determine the effectiveness of ceramics as a material for making artificial reefs on CCA growth. The effectiveness of ceramics is measured based on the type and composition of the ceramic materials. Each ceramic substrate was tested for surface texture, material composition and water absorption level. The data collected consists of water quality and CCA coverage. Differences in CCA coverage on the composition and type of material making up the ceramic substrate were analyzed using the two-way ANOVA test. The results showed that the use of 5% composition of all types of materials provided a significantly higher difference in CCA coverage, and ceramic waste (grog) provided a significantly higher difference in CCA coverage than other materials. Based on the two-way ANOVA test (P = 0.195), it shows that the interaction between the percentage of composition and the type of additional material does not significantly influence CCA coverage.   Abstrak Rendahnya ekosistem terumbu karang dalam kondisi sangat baik di Perairan Bali menunjukkan perlunya upaya rehabilitasi dan restorasi terhadap terumbu karang. Crustose Coralline Algae (CCA) berperan penting sebagai pemicu penempelan dan metamorfosis planula karang karena dapat menghasilkan sinyal kimia yang dapat ditangkap planula sebagai petunjuk melakukan penempelan pada substrat. Bahan penyusun substrat perlu diperhatikan, salah satu bahan substrat yang dapat digunakan adalah keramik. Penelitian ini secara umum bertujuan untuk mengetahui efektivitas keramik sebagai material penyusun terumbu buatan terhadap pertumbuhan CCA. Efektifitas keramik diukur berdasarkan jenis dan komposisi bahan penyusun keramik. Pada masing-masing substrat keramik dilakukan pengujian tekstur permukaan, komposisi bahan, dan tingkat penyerapan air. Data yang dikumpulkan terdiri atas data kualitas air dan tutupan CCA. Perbedaan tutupan CCA pada komposisi dan jenis material penyusun substrat keramik dianalisis dengan uji ANOVA dua arah. Hasil penelitian menunjukkan bahwa penggunaan 5% komposisi semua jenis material memberikan perbedaan tutupan CCA yang secara signifikan lebih tinggi dan limbah keramik (grog) memberikan perbedaan tutupan CCA yang secara signifikan daripada material lainnya. Berdasarkan uji ANOVA dua arah (P = 0,195) menunjukkan bahwa interaksi faktor persentase komposisi dan jenis material bahan tambahan tidak signifikan memberikan pengaruh terhadap tutupan CCA.
