Abstract

ABSTRACTThe Cilacap coastal area plays an important role in recreation, transportation, energy, education or research, residential, and industry. It is also potential for development and potential for pollution especially for oil pollution. That is caused Cilacap has the refinary oil plant and the great port of oil, furthermore it has crowded traffic of ship (both big ship or fishing ships). All of which have a tremendous potential pollute the sea and the surrounding areas. Therefore, it’s needed study of oil slick spreading that caused oil spill to formulate early warning and protection action plan for Cilacap coastal area. This study use oil spill model from DHI (Danish Hydraulic Institute) and use software MIKE-21 modul Particle/Spill Analysis. At each scenario, direction and concentration of oil spill is highly varied, its depend on the hydrodynamic condition o sea water. In January the oil spill from the 70 area pier tends to spread upstream S, Donan and around P. Nusakambangan with slick thickness between 0.0001-2.1 mm and oil spill from SPM spread out south of the model domain. In September the oil spill in the 70 area dock spreads upstream of S Donan with slick thickness between 0.001-2.7 mm and oil spills in SPM spread evenly throughout Cilacap waters with slick thickness between 0.001 to 1 mm. The result of this study is very important to plan early warning system and reduce environmental impact of oil spill. Based on comparation tide model data to tide data from field measuring, its known that both of data has no significance differences.Keywords: oil spill spreading, computational modeling, hydrodynamicsABSTRAKKawasan pesisir Cilacap memiliki potensi pengembangan wilayah yang sangat besar. Namun demikian, kawasan ini juga mempunyai ancaman terhadap pencemaran tumpahan minyak, terutama disebabkan oleh aktivitas kapal, kebocoran pipa, single point mooring (SPM), dan kapal nelayan yang dapat merusak ekosistem perairan Cilacap dan sekitarnya. Karena itu, kajian persebaran minyak diperlukan untuk menyusun tindakan peringatan dini dan perlindungan kawasan pesisir Cilacap. Dalam kajian ini dilakukan pemodelan penyebaran minyak dengan menggunakan model tumpahan minyak dari DHI (Danish Hydraulic Institute) dan perangkat lunak MIKE-21 modul Particle/Spill Analysis. Berbagai parameter inputan data diperoleh dari data sekunder dan hasil survei lapangan pada 8-14 Januari dan 10 16 September 2012. Terdapat empat model skenario penyebaran disusun dan hasil akhir divalidasi dengan hasil pengukuran. Sebagai hasil, arah persebaran dan konsentrasi tumpahan minyak untuk tiap skenario sangat bervariasi dari waktu ke waktu tergantung pada kondisi hidrodinamika perairan yang ada. Pada bulan Januari  tumpahan minyak dari dermaga area 70 cenderung menyebar ke hulu S. Donan dan di sekitar P. Nusakambangan dengan ketebalan slick antara 0,0001-2,1 mm dan tumpahan minyak dari SPM tersebar ke selatan keluar ari domain model. Pada bulan September tumpahan minyak di dermaga area 70 tersebar ka arah hulu S Donan dengan ketebalan slick antara 0,001-2,7 mm dan tumpahan minyak di SPM tersebar merata ke seluruh wialayah perairan Cilacap dengan ketebalan slick antara 0,001- 1 mm. Hasil kajian ini sangat penting sebagai dasar perencanaan upaya peringatan dini tumpahan minyak dan meminimalisasi dampak tumpahan minyak. Validasi data pasang surut hasil pemodelan dan pengukuran lapangan dari Intergovernmental Oceanographic Commission (IOC) menunjukkan tidak adanya perbedaan yang nyata.Kata kunci: persebaran tumpahan minyak, pemodelan komputasi, hidrodinamika

Abstract

In the next World Free Trade Era, presumably 70% industrial growth, especially in Java will be centered around the cities and this situation will increase environmental pollutions. The government continuously do the efforts to keep down the problems although there are also many pollution cases that couldn’t be completed. Because of lack in continous control and monitor by institution which handle environmental problems.This paper explains the role of monitoring environmental management, especially in monitoring environmental pollutions. As supporting data this paper discuss a case about using information technology in environmental managemnet in Japanesse Environmental Offices. This case shows that monitoring environmental pollutions, air water and others is an important job which is done by environmental departement in Japanese local government office. The environmental pollution monitoring has an important role in controling environmental pollutions.

Abstract

Dyera costulata, usually called as jelutung is belonging into Apocynaceae family.This plant is a potential plant species that has good prospect, especially for timberand latex production. However the seedling grows slowly. The experiment wascarried out in greenhouse, Treub Laboratory, Botani Division, Centre Research forBiology-LIPI, Bogor, using a Factorial Completely Randomized Design with treemain factors in five replications. The first factor is phase of transplant i.e. seedlingwith closed cotyledon, seedling with opened cotyledon, seedling with two firstleaves. The second factor is growth medias i.e. soil, soil+compost (1:1), soil+huskof rice (1:1), soil+compost+ soil+husk of rice (1:1:1), compost+ soil+husk of rice(1:1). The third factor is mycorrhiza i.e. 0, 2, 4 and 6 g/pot The result showed thatthe transplant phase had significant effect on the seedling growth. The best oftransplant phase is seedling with two leaves which has 100% survival, seedlingheight 8.57 cm and number of leaves 5.07 . Mycorrhiza treatment no significanteffect on the seedling growth until 5 months after planting. Growth medias hadsignificant effect at number of leaves. Therefore it is recommended the best mediafor seedling growth are are of soil+ soil+husk of rice (1:1) , or soil+compost + huskof rice = 1:1:1. There was no interaction effect of transplant phase, mycorrhizaand growth media.

Abstract

ABSTRACTConversion of lignocellulosic biomass such as Oil Palm-Empty Fruit Bunch (OP-EFB) into bioenergy is a promising solution to mitigate the impact of climate change and avoid an energy crisis that have been globally anticipated. The abundance amount of OP-EFB as a biomass waste from oil palm processing in Indonesia has opened more chance to produce bio-energy and other valuable products without having competition with the food sector. It has a high content of cellulose and hemicellulose that can be processed generating bio-energy such as biogas or bioethanol. However, to be processed into bio-energy, and other products, EFB should be pretreated first to break the recalcitrant characteristic and increase the yield and conversion rate. Alkaline pretreatment is widely known for its effectivity on lignin removal to open more access of the lignocellulose, especially for the Anaerobic Digestion (AD) process. There are several ways to evaluate Pratritmen performance before the AD process, for example by chemical analysis as well as visual observation using a microscope. Visual observation emphasizes the change in microstructure or morphology of the pretreatment process so that it can be a method for physically explaining what is happening at the microscopic level. This research’s objective is to perform microscopy observation on the OP-EFB component’s changes during the low concentrated alkaline pretreatment using NaOH 6% and mixture of NH4OH and (NH4)2CO3 10% as long as 24 hours. The result from using CLSM shows the process of delignification, while SEM shows 3 major visual changes i.e. silica bodies removal, surface degradation and the enhanced bacteria’s affinity to the OP-EFB’s surface.Keywords: Microscopy analysis, Oil palm empty fruit bunch, alkaline pretreatment, Anaerobic Digestion, visual changes  ABSTRAKKonversi biomasa lignoselulosa seperti Tandan Kosong Sawit (TKS) menjadi bioenergi adalah solusi yang menjanjikan untuk mengurangi dampak perubahan iklim dan menghindari krisis energi yang telah diantisipasi secara global. Jumlah kelimpahan TKS sebagai residu dari proses produksi minyak kelapa sawit telah membuka banyak peluang untuk menghasilkan bioenergi dan produk nilai lainnya tanpa bersaing dengan sektor pangan. TKS memiliki kandungan selulosa dan hemiselulosa tinggi yang dapat diproses menghasilkan bioenergi seperti biogas atau bioetanol. Namun, untuk diproses menjadi bio-energi, dan produk lainnya, substrat ini harus dipratritmen terlebih dahulu untuk mengatasi karakteristik rekalsitransi yang menjadi penghambat utama dalam proses biokonversi. Pratritmen dengan menggunakan reagent basa (alkalin) secara luas dikenal karena efektifitasnya pada penghilangan lignin untuk membuka lebih banyak akses lignoselulosa, terutama untuk proses produksi biogas (AD). Terdapat beberapa cara untuk mengevaluasi kinerja Pratritmen sebelum proses AD, misalnya dengan analisis kimia juga pengamatan visual dengan menggunakan mikroskop. Observasi visual menekankan adanya perubahan mikrostruktur atau morfologi dari proses pratritmen sehingga bisa menjadi metode untuk menjelaskan secara fisik apa yang terjadi dalam tataran mikroskopis. Tujuan dari penelitian adalah melakukan analisis mikroskopi dengan menggunakan confocal dan SEM pada TKS sebelum dan setelah dilakukan pratritmen dengan alkalin NaOH 6% dan campuran NH4OH dengan (NH4)2CO310% selama 24 jam juga TKS hasil pratritmen yang digunakan untuk proses produksi biogas. Hasil dari Confocal memperlihatkan adanya perubahan dari TKS sebelum dan setelah pretreatmen yaitu terjadinya proses delignifikasi, sementara hasil SEM memperlihatkan 3 perubahan visual utama yang dapat dianalisis yaitu penghilangan silika, degradasi permukaan dan peningkatan afinitas bakteri pada permukaan TKS yang dilakukan pratritmen.Kata kunci : analisis mikroskopi, tandan kosong kelapa sawit, pratritmen alkalin, Anaerobic Digestion, perubahan visual
