Abstract

Penggunaan limbah buah sebagai adsorben berbiaya rendah untuk mengurangi pencemaran akibat logam telah menarik banyak perhatian. Pada penelitian ini akan dibuat adsorben dari bubuk biji alpukat (Persea Americana Mill) yang diaktivasi menggunakan dua jenis aktivator yaitu HCl dan H2SO4. Penelitian ini bertujuan untuk melihat pengaruh aktivator terhadap bubuk biji alpukat dalam menjerap ion Pb(II). Variasi konsentrasi aktivator (2,5; 5; dan 7,5%) dilakukan untuk mendapatkan adsorben dengan kemampuan daya jerap terbaik.Hasil karakterisasi terhadap bubuk biji alpukat yang telah diaktivasi menunjukkan bahwa konsentrasi optimum HCl sebagai aktivator adalah 2,5%, sedangkan H2SO4 yaitu 7,5%. Bubuk biji alpukat yang telah diaktivasi kemudian diuji kemampuan daya jerapnya terhadap ion Pb(II). Kandungan logam Pb dalam larutan sebelum dan setelah proses adsorpsi dianalisis menggunakan metode Spektroskopi Serapan Atom. Hasil penelitian menunjukkan bahwa kedua jenis aktivator tersebut dapat meningkatkan penyerapan timbal dalam larutan jika dibandingkan hasil adsorpsi bubuk biji alpukat tanpa aktivasi. Efisiensi penjerapan bubuk biji alpukat yang diaktivasi menggunakan HCl dan H2SO4 masing-masing sebesar 96,81 dan 83,56% terhadap larutan Pb dengan konsentrasi 10 ppm. Hal ini menunjukkan bahwa aktivator HCl bersifat lebih baik dibandingkan H2SO4 dalam menjerap ion Pb(II) dalam larutan.

Abstract

AbstractThe West Sumatra Earthquake on September 30, 2009, which also hit Padang City, caused most of the buildings to be severely and slightly damaged. This paper discusses the types of damage, repairs and reinforcement of residential houses in Mekar Melati Housing, Lubuk Minturun Sub-District, Padang City, West Sumatra. Data were collected using direct survey and assessment on both houses that have been severely damaged or slightly damaged. After the 2009 earthquake, the residential houses in the Mekar Melati housing complex in Lubuk Minturun, generally suffered severe damage and slight damage. The reason is that the building there is included in the category of very simple houses. Building materials used without slof, let alone walls that only use hollowbrick material, of which if the material is not plastered it will become brittle, resulting in the building easily collapsing.Keywords: Damage, earthquake, residential houses, repairs and reinforcement.AbstrakGempa Sumatera Barat pada 30 September 2009 yang turut melanda Kota Padang telah mengakibatkan sebagian besar bangunan mengalami rusak berat dan ringan. Makalah ini membahas jenis kerusakan, perbaikan dan perkuatan bangunan rumah warga di Perumahan Mekar Melati Kelurahan Lubuk Minturun Kota Padang, Sumatera Barat. Pengambilan data dilakukan dengan survei dan asesmen secara langsung, baik rumah yang mengalami rusak berat maupun rusak ringan. Pascagempa 2009 bangunan rumah warga di perumahan Mekar Melati Kelurahan Lubuk Minturun, umumnya banyak mengalami rusak berat dan juga rusak ringan. Penyebabnya adalah karena bangunan di sana termasuk kategori rumah yang sangat sederhana (RSS). Material bangunan yang digunakan tidak memakai slof, apalagi dinding yang hanya menggunakan  bahan hollowbrick, dimana bahan tersebut jika tidak diplaster maka akan menjadi rapuh sehingga mengakibatkan bangunan mudah runtuh.Kata kunci : Kerusakan, gempa bumi, perumahan, perbaikan dan perkuatan.

Abstract

In Indonesia, almost all clean water supply for the community is carried out by the government-owned drinking water company, namely the Regional Drinking Water Company (PDAM) and is directly under the auspices of the city government. For Pekanbaru City, the provision of clean water services is carried out by the Regional Owned Enterprises, Regional Drinking Water Company (PDAM) Tirta Siak which is under the auspices of the Pekanbaru City Government. . Until now PDAM Tirta Siak still has problems relating to the amount of drinking water production. Clean water management by PDAM Tirta Siak Pekanbaru City has various problems. These problems include technical and non-technical problems. However, problems often occur due to the condition of the water source itself, often the condition of water quality, quantity and continuity is unstable. Water management problems occur due to many factors that influence it. The purpose of this study was to determine the status of the sustainability of the Tirta Siak Regional Drinking Water Company in Pekanbaru City based on 3 dimensions, namely ecology, economy and social. The analytical method uses a multi-disciplinary rapid assessment with MDS (Multidimensional Scaling) analysis. The results of the analysis show that the sustainability index value in the ecological dimension is 53.6% with a fairly continuous status where the sensitive factor is water availability, the economic dimension is 50.9% with a fairly continuous status where the sensitive attribute is collection effectiveness, while the social dimension is 49.9% with status less sustainable where the sensitive attribute is the employee training ratio.
