Abstract

SMK Harapan Bangsa yang terletak di Jl. Puradinata D9 Balaendah Bandung Jawa barat. Absensi siswa merupakan kontrol sekolah terhadap siswa-siswa yang kerap membolos sekolah, Absensi siswa juga sangat mempengaruhi kegiatan yang ada di sekolah terutama bagi kelancaran suatu sekolah. Kesalahan dalam melakukan absen dapat sangat mempengaruhi sukses tidaknya suatu sekolah dalam mengolah dan mendidik siswa. Sistem yang digunakan di SMK Harapan Bangsa Balaendah pada proses Absensi Siswa pada saat ini yaitu siswa datang langsung ke sekolah lalu siswa masuk kelas setelah bel masuk berbunyi, sebelum melaksanakan kegiatan belajar mengajar terlebih dahulu guru mata pelajaran melakukan absensi kepada siswa, proses yang dilakukan adalah guru memanggil nama siswa satu persatu dan siswa menjawab hadir lalu guru menulis hadir di dalam buku agenda atau absensi, namun jika siswa tidak ada maka guru akan menanyakan apakah siswa tersebut mengirimkan surat izin atau tidak, jika tidak ada surat izin maka guru menulis alpa, dalam penginputan absensi siswa secara manual ini dibutuhkan waktu yang relatif lama. Penelitian yang dijalankan ini bertujuan untuk menganalisis dan merancang Sistem informasi Absensi Siswa pada SMK Harapan Bangsa Yang memudahkan pihak sekolah dalam menginput absensi agar tidak ada terjadinya manifulasi atau kesalahan-kesalahan dalam melakukan absensi. Serta dapat membantu mempermudah dan mempercepat dalam melakukan absen. Dalam perancangan, sistem ini menggunakan metode Object Oriented Analysis Design (OOAD). Dan metode analisis menggunakan PIECES. Hasil dari penelitian ini menunjukkan bahwa sistem ini mampu mengelola proses absensi siswa di SMK Harapan Bangsa menggunakan PHP dan MYSQL. Dari penelitian ini dapat disimpulkan bahwa sistem absensi siswa ini dapat memberikan kemudahan bagi sekolah dan siswa dalam melakukan absensi, Sistem ini masih sangat jauh dari kata sempurna oleh karena itu penulis menyarankan untuk kedepannya bagi yang berminat untuk mengembangkan sistem ini di masa yang akan datang.

Abstract

Struvite was a white crystal known as Magnesium Ammonium Phosphate Hexahydrate (MgNH4PO4.6H2O). In industry, struvite was found in the pipes crust which the hot fluid through passes. Struvite is often used as fertilizer because it contains phosphate content. The one of benefits of struvite crystals is slow release fertilizer, so it can be more durable, which is good for the growth of the plants. The Precipitation technology is currently one of the most widely applied technologies in struvite formation. The process of forming struvite is carried out by using a vertical reactor. The process started by mixing the equimolar solutions of MgCl2, NH4OH, and H3PO4 with a concentration ratio of 1: 1: 1 and 1: 1: 2. Theprocess was carried out with the condition at the 30°C while the air inlet rate was 1.25 liters/min. The pH of the solution is pH 9 and controlled using NaOH solution. The process was carried out in the steady state condition. Then the solution was filtered and solid was dried at room temperature for 48 hours. From this study, the concentration ratio of 1:1:2 was obtained the best of struvite compared to the others ratio. The solid was analyzed by using the SEM-EDX instrument. The morphology of struvite was formed an irregular pyramid like crystal or commonly referred to as an authorhombic shape.

Abstract

Struvite is a white crystal chemically known as magnesium ammonium phosphorus hexahydrate (MgNH4PO4.6H2O). This mineral has a hardness of 1.5 to 2 Mohs. Struvite is easily soluble under acidic conditions and slightly soluble under neutral and alkaline conditions. In industry, struvite is found in the crust of pipes through which hot fluids pass. Struvite is often used as fertilizer because of its phosphate content. The formation of struvite minerals (hereinafter MAP) from laundry waste water is carried out using an aeration tank. MAP solution is made by reacting laundry waste water with Phosphoric Acid (H3PO4) and Ammonium Hydroxide (NH4OH). The MAP ratio was set at 1:1:1 with a temperature of 20 - 40 oC and an air flow rate of 0.5 - 1.5 liters per minute. The best results were at a temperature of 25oC with an air flow rate of 1 (Liter / minute) with a magnesium content of 10% and phosphorus of 42%.

Abstract

Silica carbon composite is a mixture of polar inorganic silica and non-polar organic carbon. One of the applications of this composite is as an effective adsorbent, capable of absorbing metal ions. Bagasse ash is a material that contains a relatively high amount of silica. In this study, bagasse ash will be utilized as a constituent in the fabrication of silica-carbon composites. In this study, bagasse ash was extracted with NaOH at concentrations of 1N, 1.5N, 2N, 2.5N, and 3N. The filtrate from the extraction, in the form of Na2SiO3, will undergo dilution with demineralized water at a ratio of 1:1, 1:2, 1:3, 1:4, and 1:5. The variation in NaOH concentration and Na2SiO3 dilution ratio is designed to ascertain the impact of these conditions and conditions with the Si/C content most analogous to the optimum Si/C ratio. The findings indicated that the optimal silica carbon composite was achieved at a NaOH concentration of 1.5, with a silica content of 68.3% and a carbon content of 25.76%, resulting in a Si:C ratio of 2.65:1. In contrast, a NaOH concentration of 2N, with a silica content of 55.58% and a carbon content of 35.97%, yielded a Si:C ratio of 1.54:1. The results of the XRD analysis demonstrated that the silica carbon composite did not exhibit any crystalline phase peaks. Instead, a range of 15–30° was observed, with the highest peak located at 2θ = 30.1226°. This finding indicates that the silica carbon composite is amorphous.
