Judul: Improving The Red Mud Quality Of Bauxite Mining Waste As Growing Media By Application Of Coal Bottom Ash And Humic Materials
Abstrak: Bauxite is an aluminium sourced mineral. Red mud is a waste product from that process. The waste was generated from two processes, that is washing process that separate the ore from its impurities and bauxite into qualified aluminium process. The research aims to improve the utility of red mud from washing process as a growing media by ameliorants. The ameliorants used are coal bottom ash and liquid humic materials. The research was purposed to identify the chemical characteristics of red mud before and after ameliorants application, and their effect on Gmelina (Gmelina arborea roxb.) growth. This research was conducted in a greenhouse and designed with two factors: coal bottom ash with levels of 0; 80; and 160g/2kg red mud and liquid humic materials with levels of 0; 0.05; and 0.1ml/2kg red mud with three times replications. The result showed that the red mud used in this study have low levels of fertility and nutrient content. The application of coal bottom ash and liquid humic materials significantly increases the pH, levels of P2O5 available, exchangeable Ca, Mg, and cation exchange capacity (CEC). Overall H0A2 treatment with level of coal bottom ash as much as 160 tons/ha without liquid humic materials is the most efficient level to improve the chemical properties of red mud.

Judul: The Effect of Humic Substance, Organic Matter, and Lime Ameliorant Application on the Growing of Koro Benguk (Mucuna pruriens) in Ex-Coal Mining Batulicin Mine South Kalimantan
Abstrak: One of the efforts to support the succesfully of ex-coal mining reclamation is improving land quality and choosing oppropiate plants. The application of humic substance to replace organic matter function is still limited. Koro Benguk (Mucuna pruriens) is one of a land cover crops which usually used on ex-coal mining. This plant is tolerant on acid soil, fast growing, high biomass, decomposed easily, and has a function as conservation plant which can reduce erosion. This research was aimed to study the effect of amelioran humic substances, organic matter, and lime ameliorant application on the growing of Koro Benguk and soil physical-chemical properties in ex-coal mining PT. Arutmin Indonesia, Batulicin Mine, South Kalimantan. Research has been done experimentally using descriptive analysis. This research consist of 9 treatments as follows: humic substances with dosage 2.5 l/ha; 5 l/ha; 7.5 l/ha; liming with dosage 3.45 ton/ha (50% Al-dd ); 6.9 ton/ha (100% Al-dd); lime with dosage 3.45 ton/ha (50% Al-dd) + humic substances 5 l/ha; lime with dosage 6.9 ton/ha (lime 100% Al-dd) + humic substances 5 l/ha dosage; organic fertilizer 100 ton/ha and control. All this treatments were repeated three times. The parameters which were used in this research are fresh weight and dry weight pf Koro Benguk 3.5 month after planting. Soil analysis was conducted in laboratory of Physical Land Resources Development and laboratory of Soil Physics and Conservation, Bogor Agricultural University. The results showed that application of humic substances gave the significanly increase of Koro Benguk plant biomass substantially 48.53 kg fresh weight and 11.81 kg dry weight, but was not significantly different on physicschemical properties. Liming application gave an effect on pH increased from 4.21 to 5.40 and decreasing Al from 10.17 me/100g to 0.29 me/100g. Organic fertilizer increasing C-organic from 0.16% to 0.96% and Cation Exchange Capacity (CEC) from 7.67 me/100g to 10.27 me/100g. Organic matter treatment decrease bulk density from 1.46 g/cm3 to 1.19 g/cm3.

Judul: Intrusion Detection System Untuk Pendeteksian Serangan Synflood Pada Protokol TCP/IP
Abstrak: Network Intrusion Detection System (NIDS) adalah pcnycdia pcrlindungan terhadap sistem jaringan komputer sclain dari mekanisme pcrlindungan yang telall diimplementasikan sebelumnya. Firewall scbagai salah satu alternatif pcrlindungan sistem jaringan memiliki kelemahan, yaitu hanya mampu mendcteksi paket data yang keluar dan masuk sistem jaringan yang ingin dilindungi. Pendekatan yang dilakukan oleh IDS adalah dengan melakukan proses audit terhadap segala aktivitas jaringan yang akan dilindungi. Dalam prakteknya, kejadian dalam sistem dinyatakan sebagai seknens dari pakel data yang melintasi atau memiliki tujuan ke sistem jaringan yang akan dilindungi. Penelitian ini mengenali pola serangan SYNflood untuk menentukanfinite state machine yang dapai dipergunakan dalam proses pcndeteksian.
