In this paper, effective separation of oil from both immiscible oil–water mixtures and oil-in-water (O/W) emulsions are achieved by using poly(dimethylsiloxane)-based (PDMS-based) composite sponges. A modified hard template method using citric acid monohydrate as the hard template and dissolving it in ethanol is proposed to prepare PDMS sponge composited with carbon nanotubes (CNTs) both in the matrix and the surface. The introduction of CNTs endows the composite sponge with enhanced comprehensive properties including hydrophobicity, absorption capacity, and mechanical strength than the pure PDMS. We demonstrate the successful application of CNT-PDMS composite in efficient removal of oil from immiscible oil–water mixtures within not only a bath absorption, but also continuous separation for both static and turbulent flow conditions. This notable characteristic of the CNT-PDMS sponge enables it as a potential candidate for large-scale industrial oil–water separation. Furthermore, a polydopamine (PDA) modified CNT-PDMS is developed here, which firstly realizes the separation of O/W emulsion without continuous squeezing of the sponge. The combined superhydrophilic and superoleophilic property of PDA/CNT-PDMS is assumed to be critical in the spontaneously demulsification process.

Olive Mill

Industrial oil olives have a fundamental economic importance for many countries around the Mediterranean Sea. However, during oil olive production, large amount of polluted waters known as olive mill wastewaters (OMW) are generated. Many studies have been undertaken to find efficient treatment systems and several techniques have been tested, but there have been few studies investigating sand filter or macrophytic plants for this type of effluent. The objective of this work is to study of the suitability of macrophytic plants to treat olive mill wastewater (OMW) after their passage through sand filter. The experimental pilot consists of a sand filter followed by a planted system. The sand filter is filled with 50 cm of sand and 10 cm of gravel in the top and the bottom of the filter. The alimentation (4 cm/j) is done sequentially following one day wet /three days dry cycle. In order to activate the degradation processes in the sand filter, OMW are diluted at 50% by domestic wastewater. The second step of the treatment consists of a tank (1x1x1 m3) filled with 20 cm of gravel and 60 cm of soil planted with a mixture of aquatic plants (Phragmites australis, Typha latifolia and Arundo donax) at a density of 25 young plants/m2 and irrigated two times in the week by 20L of preliminary filtered OMW. The obtained results show that the sand filter ensures a neutralization of the OMW pH which passes from 4.79 to 7.68. The enrichment of sand by the micro-organisms makes it possible to have an important mineralization of the organic matter. After ten weeks of operation of this system without clogging sign, the rate of abatement of the TSS, total COD, dissolved COD and phenolic compounds is about 70%, 79%, 76% and 81% respectively. The preliminary outputs by the planted system show a good adaptation of the tested plants to the preliminary treated OMW. The pilot allows an elimination of 94% of TSS, 99.7% of total COD, 99.5% of dissolved COD and 95% of phenolic compounds. With regard to OMW treatment efficiency, the results obtained agree with important role of macrophytes for maintaining the aquatic plants treatment capability particularly for wastewater with high organic matter.

<p>Penerapan teknologi ramah lingkungan budi daya tanaman pada suatu lahan akan dapat mempertahankan kelestarian lingkungan. Penciptaan teknologi budi daya tanaman tembakau, serat, dan minyak industri di-arahkan pada teknologi yang dapat meningkatkan produktivitas dan mutu hasil, efisiensi biaya usaha tani, dan ramah lingkungan. Teknologi ramah lingkungan difokuskan pada penemuan komponen teknologi prapa-nen yang mempunyai dampak minimal terhadap pencemaran atau perusakan lingkungan, yang meliputi va-rietas-varietas unggul, teknik pengendalian hama dan penyakit, teknik konservasi lahan tembakau. Varietas-varietas unggul tersebut adalah varietas-varietas yang mempunyai ketahanan terhadap hama dan penyakit, yaitu tembakau Prancak 95, Prancak N1, Prancak N2, Kemloko 2, dan Grompol Jatim 1; kapas: Kanesia 11–Kanesia 13; kenaf: Karangploso 14–Karangploso 15; wijen: Sumberrejo 4; dan jarak kepyar: Asembagus 81. Teknik pengendalian hama dan penyakit yang ramah lingkungan adalah teknologi pengendalian hama yang membatasi atau meniadakan penggunaan insektisida kimia sintetik dan menerapkan teknik pengendalian de-ngan memanfaatkan peran musuh alami serangga hama atau antagonis patogen penyebab penyakit, dan penggunaan pestisida nabati. Teknik konservasi lahan untuk mengendalikan erosi dan penyakit lincat dikem-bangkan pada lahan tembakau temanggung dengan menerapkan penggunaan varietas tahan penyakit, pem-buatan terassering dan penguatnya, pengolahan lahan minimal, dan aplikasi mikroba antagonis. Teknologi ramah lingkungan tersebut telah diterapkan di tingkat petani dan memberikan dampak yang positif terhadap pengembangan komoditas.</p><p>Technology innovations for tobacco, fibers, and industrial-oil crops are directed to increase production and quality of the products, efficiency, and environmentally-friendly technologies. The efficiency and environ-menttally-friendly technologies are focused on the pre-harvest technology innovations that have minimal im-pacts on environmental damages. The technologies include superior varieties, pest control, and land conser-vation. The superior varieties are those that resistant to either insect pests or diseases, i.e. tobacco: Prancak 95, Prancak N1, Prancak N2, Kemloko 2, and Grompol Jatim 1; cotton: Kanesia 11–Kanesia 13; kenaf: Ka-rangploso 14–Karangploso 15; sesame: Sumberrejo 4; and  castor: Asembagus 81.  Environmentally-friendly pest control is to limit or no use synthetic-chemical pesticides in pest control, but optimally make use the role of natural enemies and antagonists and use biopesticides. Land conservation technique to control erosi-on as well as ”lincat’ disease has been developed in fields of temanggung tobacco by using tobacco variety resistant to the disease, terracering, minimum tillage, and application of antagonist microbes. Those techno-logies has been implemented in the farmers’ fields and has a positive impacts for the commodity develop-ment.</p><p> </p>
