A lanthanum(III) ion selective electrode based on ionophore 1,10-diaza-4,7,13,16-tetraoxacyclooctadecane-N,N-diacetic acid was studied. The electrode was prepared with an inner solution system in a membrane composition that contained an active ionophore 1,10-diaza-4,7-13,16-tetraoxacycloocta decana-N,N-diacetic acid (DACDA), an anionic side potassium tetrakis (4-chlorophenyl) borate (KTCPB), a plasticizer o-nitro phenyl octyl ether (NPOE) and a polyvinyl chloride (PVC) matrix support. A good response was obtained with a slope of 19.53 Â± 1.62 mV/decade and the electrode gave responses with a detection limit of 3.92x10-6 M. The measurement range was wide (10-5-10-1 M) and the responses time was about 27 seconds. The electrode could measure lanthanum ion with a few interfering alkali, earth alkali and transition elements.

The purpose of this study is to determine the effectiveness of natural zeolite and activated charcoal to reduce levels of manganese in shall water, determine the effect of contact time with the effectiveness of separation of manganese metal in a shallow well water and know the condition before-after the adsorption process. Method that used was column adsorption with a flow system in which sample is applied to the filtration tube containing zeolite and active carbon. The tests carried out included testing of drinking water parameters namely pH and TDS, testing of manganese content in a shallow well water using Atomic Absorption Spectrophotometer (AAS). The results showed the effectiveness value of natural zeolite adsorbent and activated charcoal using an adsorption column to reduce manganese content in a shallow well water of 90.404%. The longer the use of natural zeolite and activated charcoal, the effectiveness of reducing the manganese content in a shallow well water tends to decrease. A shallow well water samples before the adsorption process have safe conditions for pH and TDS parameters, for manganese metal parameters are also still below the appropriate threshold (SNI) number 01-0220-1987 and RI Permenkes No.492 / MENKES / PER / IV / 2010, after the process of adsorption of f a shallow well water is safe for consumption.

Local wisdom is the result of the dialectic process between the individual and his environment. One of the local wisdom in Merapi Mountain, Indonesia is the traditional ceremony of Labuhan. This study is a qualitative descriptive study with literature review techniques. Based on the results of this study, it is known that the traditional ceremony of Labuhan Merapi is one of the local wisdom, tradition, culture, and traditional intelligence in the residents of the southern slope of Mount Merapi. Merapi's traditional ceremony is one of the traditional intelligence that can be managed in building a community-based disaster risk reduction system, especially at the disaster mitigation stage. Traditional intelligence is formed from the results of people's interaction with their physical environment over a long period of time. The formation of traditional intelligence allows people to know and read the signs of nature related to the eruption disaster of Mount Merapi.

The transport mechanism of lanthanum element in the supported liquidmembrane with macrocycle compound Di benzo IB crowns 6 carriers was studied. These transport are two kinds. that is chemical transport and potential transport. The chemical transport is done with two cell compartment (feed compartment and stripping compartment). and separate with membrane that prepare with DiBenzoIBCrown6. Poly Vinyl Chloride. Di Octyl Ptalate, Sodium tetra butyl borate in Tetra hydro furan solution. A 150 mL solution of La3+ JO-3 Min feed cell stirrer with300 rpm speed along 3 hour. The stripping phase is solution that varied the pH from 1 to B. The same way. then solution in the feed cell is varied from 10-1 M to 5.10-4 M. The potential transport is measured with the relative same cell. The potential transport measure with two kind reference electrode. Ag/AgCI reference electrode in the inner cell and calomel reference electrode in the outer cell. Inner cell is contain mixture solution KCL 10-3 M and La3+ IO-3 M and outer cell is contain solution La3" that variedfrom 10-8 to JO-J M. The chemical transport is effective at low pH (below pH 4) and high pH (upper pH 6). It is good way for separation of La3'. The transport ion La3+ is low at pH 4 - 6. It is good areafor applied as sensor membrane electrode that has minimal diffusion potential. The system has good correlation in potential membrane that gives slope value 19.36 as Nernst coefficient.

Penelitian ini bertujuan untuk memisahkan ion logam besi dan mangan pada air sumur (dalam) menggunakan metode adsorpsi kolom. Berdasarkan penelitian, diketahui efektivitas metode adsorpsi kolom untuk penurunan kadar logam besi dan mangan pada air sumur, efisiensi waktu penjerapan terhadap ion logam besi dan mangan, serta kondisi air sumur sebelum dan sesudah adsorpsi. Penelitian dilakukan pada air sumur (dalam) Wonoboyo, Kecamatan Jogonalan, Kabupaten Klaten. Proses adsorpsi menggunakan kolom berisi zeolit dan karbon aktif sebagai adsorben. Pada penelitian ini efektivitas pemisahan logam besi dan mangan dari air sumur (dalam) diketahui dari nilai efisiensi penjerapannya. Analisis logam besi dan mangan dilakukan dengan Spektrofotometri Serapan Atom (AAS). Selain itu juga dilakukan uji parameter air yaitu pH dan TDS. Hasil penelitian menunjukkan bahwa semakin lama proses adsorpsi, maka efektivitas adsorben zeolit dan arang aktif dalam menurunkan kadar Fe dan Mn meningkat. Efisiensi penjerapan cukup tinggi dengan rata-rata 97,50% untuk Fe dan 98,33% untuk Mn. Air yang sebelumnya keruh menjadi jernih dengan pH dan TDS yang semakin kecil, sehingga air lebih aman dikonsumsi karena semakin jauh dari nilai ambang batas yang ditetapkan dalam SNI dan permenkes RI N0.492/MENKES/PER/IV/2010.

Abstract This research aims to prepare an adsorbent from Kelud volcanic ash for better Cu(II) adsorption efficiency than Kiesel gel 60G E'Merck. Adsorbent synthesis was done by dissolving 6 grams of volcanic ash activated 700oC 4 hours and washed with HCl 0.1 M into 200 ml of 3M sodium hydroxide with stirring and heating of 100 °C for 1 hour. The filtrate sodium silicate was then neutralized using sulfuric acid. The mixture was allowed to stand for 24 hours then filtered and washed with aquaDM, then dried and crushed. The procedure is repeated for nitric acid, acetic acid and formic acid with a contact time of 24 hours. The products were then characterized using FTIR and XRD, subsequently determined acidity, moisture content, and tested for its adsorption of the ion Cu (II) with AAS. The results showed that the type of acid that produced highest rendemen is AK-H2SO4-3M ie 36.93%, acidity of the adsorbent silica gel synthesized similar to Kiesel gel 60G E'Merck ie adsorbent AK-CH3COOH-3M and the water content of the silica gel adsorbent synthesized similar to Kiesel gel 60G E'Merck ie adsorbent AK-H2SO4-2 M. The character of the functional groups of silica gel synthesized all have similarities with Kiesel gel 60G E'Merck as a comparison. Qualitative analysis by XRD for all modified adsorbent showed a dominant peak of SiO2 except adsorbent AK-H2SO4 amorphous and chemical bonds with FTIR indicates that it has formed a bond of Si-O-Si and Si-OH. The optimum adsorption efficiency of the metal ions Cu(II) obtained from AK-H2SO4-5M adsorbent that is equal to 93.2617% and the optimum adsorption capacity of the Cu(II) metal ions was obtained from the adsorbent AK-CH3COOH-3M is equal to 2.4919 mg/ g.

This research aims are to separate of Ca and Fe metal ion in source water, with local zeolite and active carbon by adsorption column technic. Efficiency of separation are control by adsorption time and size of zeolite. Method that used was column adsorption with a flow system in which sample is applied to the filtration tube containing zeolite and active carbon. Initial and final concentrations of the samples were analyzed using Atomic Adsorption Spectrophotometer instrument. The results obtained shows that ability adsorption of zeolite to Ca and Fe metal ion are a good. Zeolite 1 (10 mesh) can reduce iron concentration until 93.98 % and zeolite 2 (5mesh) until 98.88% for 1 – 4 week range time. Whereas reducing of calcium concentration is not good, until 2 week period time adsorption of calcium ion is about 50%. Keywords: adsorption, zeolite, source water
