Abstract

Seasonal characteristics of vegetation, such as growing season are closelyrelated to characteristics of the lower atmosphere, and are thereforeimportant variables in global models and vegetation monitoring. NormalizedDifference Vegetation Index (NDVI) data derived from the National Oceanicand Atmospheric Administration’s (NOAA) Advanced Very High ResolutionRadiometer (AVHRR) satellite sensor offer a means of efficiently andobjectively evaluating vegetation response over large geographic areas.Those vegetation responses were computed based on time-series NDVIdata collected from May 1997 to April 1998 over South East Asia. Measureof growing season was computed and analyzed for land cover type. It isdifficult if not impossible to objectively define an absolute the time of thegrowing season from satellite observations. The purpose of this paper isto determine the threshold of the growing season by using GeographicInformation System (GIS).

Abstract

Dalam penggunaannya, air mempunyai persyaratan tertentu, baik untuk air rumah tangga maupun air industri. Salah satu syarat yang harus dipenuhi adalah angka kesadahan air, yaitu angka yang berhubungan dengan jumlah kandungan calsium dan magnesium. Kedua unsur ini khususnya pada air minum diperlukan, namun hanya sampai dengan batas tertentu, karena kelebihan unsur ini dapat berakibat pada kesehatan. Pada penggunaan air untuk cuci dan mandi kelebihan unsur calsium dan magnesium akan mengurangi efektifitas sabun/detergen, bahkanuntuk air industri kandungan unsur-unsur tersebut sebaiknya nol, karena adanya kedua unsur ini dapat merusak peralatan pemanas pada industri.Untuk membantu masyarakat, terutama pelaku industri kecil dan industri rumah tangga, telah dilakukan penelitian mengenai cara penghilangan kandungan unsur calsium dan magnesium dari dalam air . Dalam tulisan ini diinformasikan beberapa cara penghilangan kesadahan air atau biasa disebut dengan pelunakan air, namun percobaan yang dilakukan hanya terbatas pada cara pelunakan air sadah dengan metoda penukar ion. Bahan penukar ion yang digunakan adalah zeolit alam, karena zeolit alam mudah diperoleh dan harganya relatif murah. Hasil percobaan menunjukkan adanya penurunan kadar kesadahan, namun zeolit alam ini cepat sekali mencapai jenuh, sehingga harus sering dilakukan proses regenerasi.

Abstract

Ninety percent from approximately 1200 plant species belonged to Piper genus(Piperaceae) have not been explorated their phytochemical potency and biological activities. Piper miniatum has beeing used traditionally in Papua as spices and tonic. However, the propagation effort has never been done yet so its population in nature is decresed gradually. Therefore, simple propagation is conducted that can be adopted by the local people in order to cultivate as well as to explore its potency as antibacterial agent. The propagation experiment was carried out using air layering method with variable treatment of internode maturity ( R1, R2, R3 ), growth medium (Selaginela sp.,Asplenium nidus root, compost) with completely randomized design with 10 replications.Air layering media using Asplenium nidus root of 18 weeks gave the best respon.Key words: Piper miniatum, Air layering.

Abstract

Sandalwood (Santalum album L) is one of the tropic plants that have high economicvalue. Sandalwood exploitation in East Nusa Tenggara province has very longhistory perhaps more than 1000 years therefore unforgetable. Now a dayssandalwood was categorized as rare plant. One of the several ways to conquerthe rare of sandalwood is to build the garden of sandalwood seeds in Kian RaiIkun, Belu Regency. Some steps of these activities are, to inventory the motherseeds trees in Belu and Timur Tengah Utara Regency, seeds collecting, seedgermination and furthermore sandalwood seedlings are planted in the garden ofsandalwood seeds in Kian Rai Ikun, Belu regency. This garden is located about450 m above sea level (asl).On inventory activity were found 5 mother seeds trees located in Biau (Bi) about500 m asl, Alas (Al) 500 m asl, Haitimuk (Ha) 100 m asl, Oesena (Oe) 500 masl and Tialai (Ti) 450 m asl. Planting of sandalwood seedling in this garden arecoordinated to available planting plot. Every planting plot was grown about 200– 250 sandalwood seedlings from the same mother seeds tree. Some activitiesto maintain sandalwood seedling in the garden after planting time are, watering,weeding and pruning the branch. The aim of branch pruning on sandalwoodtrees is to protect the plant from wind disturbance in order not fall down. In ourexperience sandalwood seedling fall down easily if seedling has dense of branchesand leaves.This research was purposed to study the effect of mother seeds trees and branchpruning on sandalwood growth in the field. The result shown that branch pruningdid not give significantly different on sandalwood growth but the mother seedstrees gave significantly different on sandalwood growth in the field during 1 –10 months after pruning. The sandalwood plants from Haitimuk mother seedstree possess the highest in height and branch growth than other plants, while thesandalwood plants from Oesena mother seeds tree possess the lowest in heightand branch growth. The growth of sandalwood in field followed the models oflogistic growth with high determination coefficient about more than 0. 85.

Abstract

The organic concentration of soft drink factory waste water has not high organic concentration, therefore one of the alternatives of the treatment technology is using aerobic system : activated sludge. On this observation can be seen that the system can be used as waste water treatment for soft drink that is not so high in COD contain and the criteria parameters design can be fulfilled by process parameters during operation the system. The parameters that are not fulfill the design parameters is caused by the shock loading of toxic material or by the high loading rate of substrate of waste water. Based on parameter criteria as mention above, the efficiency that can be reached of this process is about 61,22%.

Abstract

ABSTRACTPulo Ampel Industrial Zone in Serang Regency is an industrial zone with a high level of threat from a technological hazard. One possible route this threat can be manifested is in the form of explosion potential from the storage and transport tanks of toxic and dangerous materials e.g. Ethylene and Butadiene gases. Within the framework of disaster risk reduction, disaster risk analysis is carried out which includes the analysis of threats and vulnerabilities along the path of transport of these hazardous materials. To determine the level of explosion hazard, due to the occurrence of transportation accidents, modeling using ALOHA® (Areal Locations of Hazardous Atmospheres) software, which was developed by the United States Environmental Protection Agency (US EPA), was carried out. The model used in this study was the BLEVEs (Boiling Liquid Expanding Vapor Explosions) scenario during gas transportation using ISO Tank, which represents the worse possible scenario. Meanwhile, disaster vulnerability analysis is calculated based on social vulnerability aspect which includes population density and vulnerable group parameters by utilizing the scoring method in accordance to Head of BNPB Decree No.2 of 2012. Based on the hazard and vulnerability level, disaster risk maps are obtained along the Ethylene and Butadiene transport lines covering the information related to the area of the explosion which intersected with population settlement in Serang Regency, Banten Province.Keywords: risk reduction, trasportation, hazardous materials, vulnerabilities, explotionABSTRAKZona Industri Pulo Ampel di Kabupaten Serang merupakan zona industri dengan ancaman bencana kegagalan teknologi yang relatif tinggi. Ancaman bahaya yang dapat ditimbulkan diantaranya berupa potensi ledakan dari tangki-tangki penyimpanan maupun tangki transportasi bahan  berbahaya dan beracun (B3) terutama gas Etilena maupun Butadiena. Dalam rangka pengurangan risiko bencana, maka dilakukanlah analisis risiko bencana terhadap tangki transportasi B3 yang meliputi analisis ancaman dan kerentanan di sepanjang jalur transportasi B3 tersebut. Untuk menentukan salah satu tingkat bahaya yang berupa ledakan akibat kecelakaan transportasi gas dilakukanlah pemodelan dengan menggunakan perangkat lunak modeling ALOHA® (Areal Locations Of Hazardous Atmospheres) yang dikembangkan oleh United States Environmental Protection Agency (US EPA). Model yang digunakan di dalam kajian ini menggunakan skenario ledakan terburuk berupa skenario BLEVEs (Boiling Liquid Expanding Vapor Explosions) pada saat transportasi gas menggunakan ISO Tank. Sementara analisis kerentanan bencana dihitung berdasarkan aspek kerentanan sosial yang meliputi parameter kepadatan penduduk dan kelompok rentan dengan menggunakan metode skoring sesuai Perka BNPB No. 2 Tahun 2012. Berdasarkan tingkat bahaya dan kerentanan tersebut diperolehlah peta risiko bencana di sepanjang jalur transportasi gas Etilena dan Butadiena yang meliputi informasi terkait luas area permukiman penduduk terdampak ledakan di Kabupaten Serang, Provinsi Banten.Kata kunci: pengurangan risiko, transportasi, bahan beracun dan berbahaya, kerentanan, ledakan
