The increasing of industrial activity on the Gresik Regency will increase the generated waste. One of the generated waste from industrial activity is hazardous waste which contain Lead (Pb). Pb which are disposed to the environment, especially to the sea, will pollute the environment and endanger the life of marine animals like fishes and other marine biota. Therefore, the research of Pb distribution was conducted on the coastal area of Gresik Regency. Sea water samples were taken from 3 different points, Petrokimia Port, Manyar Sub-regency, and Maspion V Industrial Area. Sampling used purposive sample method and samples were analyzed by AAS. Results showed that the highest Pb concentration at Maspion V Industrial area (0.083 mg/L). Meanwhile the lowest Pb concentration at Manyar Sub-regency (0.021 mg/L). Industrial activity that are conducted at Gresik Regency may generate Pb which can pollute the seawater. Keywords: coastal area, Gresik, hazardous waste, lead, seawater

The abundance of plastic waste is caused by inadequate management. The element of plastic waste consists of crude oil and natural gas that can be reuse as fuel. The conversion technique which can be applied is thermal cracking as known as pyrolysis that combined with a catalyst. The addition of a catalyst can accelerate the process of crude oil formation so that the volume increases and makes the quality better. The pyrolysis can convert waste into oil up to 81% that are consist of paraffin, isopropyl, olefin, naphthal and aromatics so feasible to use as fuel. Keywords: catalyst, crude oil, fuel, plastic waste, pyrolysis.

The contribution of the mining sector to forest destruction in Indonesia reaches 10% and now drove to 2 million ha every year. To overcome this problem, it is necessary to reclaim the former mining area. One of the determinants of the success of reclamation is plant’s selection, in accordance with the condition of the land. In this case for revegetation activities need to pay attention between plant’s selectionspecies and plant growth requirements with the condition of the land, so that the reclamation success criteria can be achieved. This research uses descriptive analysis method, this method is done by describing the facts which followed byanalysis and provide sufficient understanding and explanation. Techniques of data collection using comparative analysis method by comparing various journals and other literature. Criteria for selection of tree species for ex-mining land can be seen from:(1) local species of pioneer, (2) fast growing but not in high cost, (3) produces litter that easy to decompose, (4) good root system and able to do reciprocal relationship with certain microba, (5) seed carrier, (6) easy and cheap in propagation, planting and maintenance. The success of revegetation depends on several things such as: preparation of planting, crop, plant maintenance and plant monitoring. Keywords: mining, reclamation, plant, revegetation

The quality of environment especially the water bodies need to be improved on the pollution load of the household wastewater, which in general still does not have a liquid waste treatment plant. Electrocoagulation used in this research because of the simple and efficient method. The aim of study to know the ability of electrocoagulation method for reducing the concentration of COD and TSS in the wastewater from household textile industry. The sample was taken from the residual wastewater of textile dye (sarung) with a liquid waste requirement of 36 liters. The data for the analysis is the initial and final parameters data were COD and TSS. The electrodes were used aluminum (Al) as an anode and iron (Fe) as a cathode. The research variations were used the number of electrodes and the voltage. The results showed that the treatment of 4 electrodes with 12volt voltage could reduce the COD concentration up to 76% and TSS up to 85% in household wastewater of household textile industry. Keywords: COD, electrocoagulation, liquid waste, TSS

IPLT of siak district is installation mud feces built in the district siak riau that launcher to serve around more or less 100.000 soul. The district siak generally soil structure consisting of land podsolik red yellow of rock and alluvial and tanah organosol and gley humus in the form of rawa-rawa or moist soil and building planned to be supplied bracing the ground as the kerucuk. This study aims to analyze the foundation of the kerucuk at every stage IPLT processing. Discharging from pillars foundation kerucuk is created one alternative for bracing of the ground at the land of pulpy/of land the wetness of ground a bog that are requisite and suited to increase carrying capacity of the land or reducing the incidence of of land subsidence related as a result of the construction of units liquid waste processing installations mud fecal matter kabupaten siak. Calculation a power capacity of support pillars foundation kerucuk performed on stage IPLT processing units siak district riau namely anaerobic ponds, the pool facultative, the pool maturasi, the pool solid separation chamber (SSC) and ponds in which a drying sludge bed (SDB). The analysis shows that the capacity of permission to one piece the foundation a wooden pole kerucuk with long in the depths of 12 ft 8 m from the surface of the native land of 4,648 tons. Keywords : mud feces, IPLT, kerucuk pilar foundation.

Lahan adalah suatu lingkungan fisik yang meliputi tanah, iklim, relief, hidrologi, dan vegetasi dimana faktor-faktor tersebut mempengaruhi potensi penggunaannya (Hardjowigeno dan Widiatmaka, 2001). Sesuai dengan pendapat Arsyad dalam Setyowati (2016), penggunaan lahan (land use) dapat diartikan sebagai campur tangan manusia terhadap lahan, baik secara menetap maupun berkala untuk memenuhi kebutuhan hidup baik material maupun spiritual. Kualitas tanah merupakan kapasitas dari suatu tanah dalam suatu lahan untuk menyediakan fungsi-fungsi yang dibutuhkan manusia atau ekosistem alami dalam waktu yang lama (Plaster, 2003). Menurut Nazam dan Suriadi (2008), apabila tanah tidak mampu untuk memenuhi fungsinya akan mengakibatkan terganggunya kualitas tanah sehingga menimbulkan bertambah luasnya lahan kritis, menurunnya produktivitas tanah dan pencemaran lingkungan. Metode yang digunakan adalah metode deskriptif, yaitu menggambarkan dan mendeskripsikan hasil studi literature yang terkait dengan penggunaan lahan, kualitas tanah dan pengaruh penggunaan lahan terhadap kualitas tanah. Berdasarkan pada hasil pengkajian dan pembahasan penggunaan lahan serta pengaruhnya terhadap kualitas tanah, maka dapat disimpulkan sebagai berikut : tingkat IKT pada penggunaan lahan dengan pola wanatani dengan dominasi tanamn ketela pohon dan jati lebih tinggi dari pola wanatani dengan campuran berbagai jenis pohon, pengelolaan seresah yang dibenam dapat meningkatkan kandungan bahan organic dalam tanah dibandingkan dengan seresah yang dibakar, tanah hutan memiliki IKT tertinggi karena belum adanya pengelolaan tanah yang dilakukan, teknik konservasi pada lahan miring dilakukan dengan pembuatan teras bangku yang dilakukan dengan penanaman tanaman penguatdapat menurunkan tingkat erosi pada tanah, sebaliknya jika tidak dilakukan dengan penanaman tanaman penguat dapat meningkatkan tingkat erosi, pemupukan yang dilakukan dengan cara dibenam dapat menjadikan unsur hara dalam tanah lebih banyak dibandingkan dengan pemupukan yang dilakukan dengan cara disebar, pemanfaatan lahan untuk sistem penggunaan lahan yang baik akan menjadikan lahan memiliki indeks kualitas tanah yang tinggi. Kata kunci : penggunaan lahan, unsur hara, kualitas tanah
