Abstract

Rhodamine B contributes significantly to environmental pollution, because it is nonbiodegradable, toxic and harmful to the environment. One effort to reduce the amount of Rhodamine B is the adsorption process. The purpose of this study to determine the effect of adsorption temperature, pH, adsorbent mass. Knowing the optimum conditions for reducing the levels of dye in the water, as well as determine the adsorption equilibrium modelsRhodamine B using fly ash oil modified with 1.4 NaOH as an adsorbent. fly ash modification processes are done by mixing fly ash and NaOH in the ratio 1: 4. The adsorption process isconducted by mixing fly ash oil and pH solution of rhodamine B. The optimum conditions for reducing the levels of rhodamine B in water is the adsorbent mass of 5 g/L, temperature of45°C and pH 2. Thermodynamic data such as ΔH, ΔG and ΔS were calculated. And the mechanism of rhodamine B dye adsorption by fly ash oil is dominated by Freundlich isotherm models representing physical adsorption.Keyword: Adsorption, Rhodamine B, Fly Ash, Isothermal Adsorption

Abstract

Farm and agro wastes from area which population has their livehood from farming and agriculture will result in the environmental and health issues if there is lack treatment on those wastes. One of the solutions to overcome these problems is to convert farm and agro wastes into organic fertilizer, which is produced from living substances weathering (plants and animals). Organic fertilizers are available in the form of solid or liquid and contain a lot of organic materials than nutrient levels, thus can improve plant growth. Other advantages of organic fertilizer are cheaper than synthetic ones, environmentally friendly, and are able to decrease negative effects of chemical fertilizers. Organic fertilizer can be made individually or in group of people. The objectives of this activity are to introduce the knowledge and train rural community of Kecamatan Rambah Hilir, Desa Pasir Utama Kabupaten Rokan Hulu, Provinsi Riau in making organic fertilizer using farm and agro wastes. The methods use in this activity are through socialization and training on making organic fertilizer from farm and agro wastes to Desa Pasir Utama community. Organic fertilizer was made by mixing cow manure with straw cuts, followed by addition of palm sugar activated effective microorganisms 4 (EM4). The mixture was left to incubate for 4 weeks and aerated every three days to allow good fermentation. This community service activity supports government program in encouraging growth of reusing farm and agricultural wastes that will increase agricultural productivity of rural community.

Populasi penelitian ini adalah seluruh siswa kelas XI SMA Swasta Swadaya Hamparan Perak yang berjumlah  32 siswa. Sehingga yang menjadi sampel dalam penelitian ini adalah seluruh siswa kelas XI SMA  sebanyak 32 siswa. Metode yang digunakan dalam penelitian ini adalah metode eksperimen dengan model  one group pre test post test. Instrumen yang digunakan untuk menjaring data adalah tes essay dalam bentuk penugasan yaitu menulis teks prosedur kompleks. Pengujian hipotesis dilakukan dengan menggunakan uji “t”. Hasil penelitian menunjukkan bahwa kemampuan siswa dalam menulis teks prosedur kompleks dengan tanpa perlakuan metode praktek termasuk dalam kategori cukup dengan nilai rata-rata 68,1 sedangkan sesudah perlakuan metode praktek  termasuk dalam kategori baik dengan nilai rata-rata 79,5. Selanjutnya pengujian hipotesis menunjukkan thitung> ttabel atau 4,45> 2,04 pada taraf signifikan  = 0,05. Dengan demikian, telah terbukti bahwa hipotesis nihil (Ho) ditolak dan hipotesis alternatif (Ha) diterima yaitu metode praktek lebih berpengaruh dalam meningkatkan kemampuan menulis teks prosedur kompleks siswa kelas XI SMA Swasta Swadaya Hamparan Perak.

Abstract

Bulan Ramadhan adalah momentum untuk meningkatkan intensitas kegiatan peribadatan seorang insan, pun sebagai momentum pendidikan bagi pelajar untuk dapat menjadi seseorang yang memiliki kemampuan mengendalkan hawa nafsunya dan mempunyai dorongan dan motivasi untuk senantiasa beramal shaleh. Hal tersebut semakin rizkan untuk dilakukan dengan lengangnya kegiatan belajar-mengajar di sekolah yang mengkhususkan bulan Ramadhan sebagai bulan Dinul Islam (Pengajaran Islam Intensif). Tujuan pengabdian agar dapat meningkatkan motivasi ibadah siswa melalui kegiatan pesantren kilat. Pengabdian dilaksanakan di SD Negeri 03 Tripe Jaya, Kampung Uyem Beriring, Kecamatan Tripe Jaya, Kabupaten Gayo Lues. Kegiatan pesantren kilat menjadi penting, demi menjaga semangat dan antusiasme ibadah siswa. Pesantren Kilat Uyem Beriring 2022 selanjutnya menjadikan siswa/siswi SD Negeri 03 Tripe Jaya menjadi insan yang terbiasa mengisi kegiatan Ramadhan dengan kegiatan ibadah.
