Studi Pendahuluan Pengolahan Air Payau Menjadi Air Bersih Dengan Metode Kombinasi Elektrokoagulasi Dan Adsorpsi Menggunakan Karbosil
Authors: Heriani R.N. Eny , Simanjuntak Wasinton , . Ilim 
Published: May 2020

This study was carried out to investigate treatment of brackish water using a combination of electrocoagulation and adsorption using carbosil prepared from rice husk with pyrolysis method. Electrocoagulation was applied with the aim to remove natural organic matter in the sample, using aluminim as electrodes, with the particular purpose to study the effect of potenstials.For this purpose, electrocoagulation experiments were conducted at potential of 4, 6, and 8 volt at fixed contact time of 60 minutes.The performance of the method was defined in term of absorbance reduction at the wavelengths of 254 and 285 nm, since the absorbance at these two wavelenghts was found to correlate well with the amount of organic matter in the water samples. The treated water was then subjected to adsorption process at different contac times of 5. 10, and 15 minutes, and the performance of the process was evaluated in term of electrical conductivity reduction.The results obtained indicate that for electrocoagulation process, the higest reduction of natural organic matter content was achieved using potential of 8 volt, and adsorption porcess of 15 minutes was found to result in reduction of electrical conductivity from 15.13 mS/cm to 10.10 mS/cm.Characterization of the carbosil using SEM/EDX technique revealed that the carbosil has practically homogeneous surface and able to adsorb salt and several other elements from the brackish water.

The damage of mangrove forests stimulate Anopheles sp. migrate to other habitats such as settlements, that become malaria vector. The purpose of this research was to determine the effect of mangrove forest ecosystems both intrinsic and extrinsic factors in immunity to malaria. This research was conducted on June 2014 in the Muara Gading Mas Village, Bandar Negeri, Sriminosari, and Margasari, Sub-district Labuhan Maringgai, District East Lampung. The data were collected through interviews and survey/observations method. The impact of each variable used binary logistic regression models. Parameter optimization used software Minitab 16.

Kadam is one type of fast growing trees species. One of the factors that affect plant growth are nutrients, the use of organic fertilizer such as cow manure compost soil mix additive during planting can increase nutrient substances in the soil that plants need for growth. The purpose of this experiment was to study the growth response of kadam seedling at different mixing ratio betwen soil with cow manure compost at seedling growth media and the best comparison of soil mixed with cow manure compost where gave the best effect on the growth of kadam seedling. The experiment was conducted from March until June 2012 in the nursery PT Subur Anugrah Sejahtera, District of Kaur, Sub District Air Palawan. The method used in this experiment was randomized block design (RBD) with 5 groups and 5 treatments. Treatment of this experiment were growth media consisted of top soil, top soil + compost (1:1), top soil + compost (1:2), top soil + compost (1:3) and top soil + compost (1:4). Each experimental unit consisted of 10 seedlings. Similarity variety tested with Bartlett test, then performed analysis of variance and comparison of average values between treatments with HSD test, all the tests done at 5% significance level. The results showed that composition of soil and cow manure compost significantly affect to height, seedling height, dry weight of root, and seedling quality index.

Abstract— In these past few years, issues regarding homosexuality are growingrapidly. These issues, of course, cannot be taken lightly nor be ignored anymore asthey are slowly but surely surrounding us all. Looking through religion’s shoes—as religion cannot be taken away from Indonesian’s lifestyle that ideally upholdingthe values ofPancasila, many condemning homosexuality, and Christian is one ofmany religions that also refuse and condemn the act of it. In popular Christiandoctrine, it is said that homosexuality is a form of sin and brings sorrow to the heart of Christ. However, is it really the only doctrine about homosexuality in Christian?The answer is no. There is another doctrine which is more accepting and welcominghomosexuals as a part of them, and people barely have their feet submerged in thisone. This doctrine is never really discussed. Therefore, this research exists. Thereare two participants of this research. Both of them are priests and come from twodifferent doctrines and perspectives; accepting and condemning homosexual. Thisresearch is using priest as the participant because of their knowledge are assumedas suffice to gain the title and they are the biggest agent to spread the gospel whichpeople usually listen and look up to.

Abstrak—Dalam beberapa tahun belakangan ini, isu homoseksual berkembangsangat pesat. Isu ini tentu tidak dapat dihindari lagi. Tidak mungkin untuk masyarakat terus-terusan menutup mata. Melihat dari sisi agama yang tidak dapat lepas dari kehidupan masyarakat Indonesia yang idealnya menjunjung tinggi Pancasila dalam kehidupan sehari-hari, banyak ajaran agama yang menolak homoseksual secara tegas—ajaran agama Kristen salah satunya. Dalam ajaran Kristen yang dominan diyakini umat, perilaku homoseksual adalah sebuah dosa dan benar-benar mendukakan hati Tuhan. Namun, apakah ajaran tersebut adalah satu- satunya ajaran mengenai homoseksual yang ada di dalam Kristen? Tidak. Ada ajaran lain yang mendukung kaum homoseksual dan tidak banyak yang tahu mengenai ajaran tersebut. Maka dari itu, penelitian ini ada untuk mengisi kekosongan ilmu tersebut. Ada dua pendeta yang akan diwawancarai. Dua pendeta tersebut berasal dari dua kubu yang berbeda, yaitu kubu yang menerima dan yang menolak homoseksual. Penelitian ini menggunakan pendeta sebagai narasumber karena dalam suatu praktik keagamaan, pendeta adalah agen terbesar dalam menyebarkan ajaran agama atau teologi. Mereka dijunjung tinggi sebagai seseorang yang memiliki dampak terbesar kepada umat-umat pemeluk agama Kristen. Hal- hal yang dikatakan oleh pemimpin agama sering kali langsung diamini oleh umat.

Abstract— The goal of this research was to find out the relation between authoritative parenting and the independence of down syndrome children in doing activity daily living. The participants in this study were 33 parents who had down syndrome children. The sampling technique in this study was conducted by purposive technique. Data collection techniques were carried out by distributing questionnaires for the Parenting Style Dimension Questionnare (PSDQ) and Functional Indpendence Measure for Children (WeeFIM). The results of hypothesis testing using Pearson correlation were found a significantly positive between authoritative parenting and the independence of down syndrome children in performing daily living activities (r = 0.498 <0.05; r = 0.498). Based on the results of the crosstab, significant associations were found between parents' education, children's age, parents' thoughts about the child's condition, parents' feelings of having down syndrome children, parental treatment to improve children's abilities, and parental treatment of the child's condition with significant associations with independence of down syndrome children in doing activity daily living
