Abstract

Penelitian ini bertujuan untuk mengukur emisi partikel ultrafine dari asap pembakaran rokok kretek dan mempelajari pengaruh penambahan asam amino dan zat aditif tertentu pada rokok kretek (yang disebut divine kretek) terhadap emisi partikel ultrafine yang dihasilkanya. Pengukuran dilakukan dengan metode micro-environmental chamber dengan instrument pengukur TSI P-TRAK 8525 Ultrafine Partikel Counter.  Hasil penelitian menunjukkan bahwa penambahan asam amino dan zat aditif tertentu  pada divine kretek meningkatkan jumlah partikel ultrafine yang dihasilkan. Peningkatan jumlah partikel ultrafine yang terjadi bervariasi dalam range 26-77 % tergantung dari jenis zat aditif yang ditambahkan. Rokok kretek referensi menghasilkan emisi partikel ultrafine pada nilai 3,35 x 1010 partikel/batang. Peningkatan nilai faktor emisi sebesar 26,66% didapatkan pada rokok dengan penambahan glutamic acid. Sementara peningkatan terbesar didapatkan pada rokok dengan penambahan asparagine (77,38%), diikuti dengan rokok dengan penambahan phenylalanine (73,24%) dan vitamin E (72,05%).

Abstract

Kebanyakan hotel yang berkembang saat ini menggunakan jasa reservasi kamarnya kepada agen online pemesanan kamar, dikarenakan hotel itu sendiri tidak mempunya aplikasi yang dapat menunjang dan memberikan pelayanan dari pemesanan kamar yang dilakukan terhadap calon pelanggan secara online. Maka dari itu dibuatlah proses pemesanan kamar secara online oleh pihak manajemen hotel itu sendiri tanpa menggunakan jasa dari agen pemesanan kamar. Dengan begitu data yang dimasukan oleh calon pelanggan bisa langsung masuk dan diproses oleh pihak manajemen hotel, dan dapat pula memasarkan produk-produk yang ada di hotel tersebut tanpa menyewa atau membayar pemasangan iklan terhadap website agen pemesanan kamar. Dengan adanya website manajemen pemesanan kamar secara online, kinerja hotel akan lebih maksimal dan lebih menambah nilai jual itu sendiri.

Abstract

Penggunaan teknologi penginderaan jauh di bidang kehutanan merupakan salah satu pilihan yang tepat untuk memperoleh data yang cepat, akurat dan relatif murah untuk mendeteksi perubahan penutupan dan penggunaan lahan. Data series citra satelit dengan resolusi spasial yang tinggi digunakan untuk mendeteksi perubahan penutupan lahan di Kawasan Hutan Lindung Reg 22 Way Waya Kabupaten Lampung Tengah dalam kurun waktu 10 tahun terakhir, yaitu tahun 2000, 2004 dan 2010. Metode yang digunakan dalam penelitian ini yaitu metode klasifikasi terbimbing (supervised classification). Hasil analisis citra dan cek lapang menunjukkan adanya perubahan luasan dari masing-masing jenis penutupan lahan. Hutan sekunder (Hs) mengalami penurunan luas tutupan ± 5,2 % pada tahun 2004 dibandingkan dengan penutupan tahun 2000. Pada tahun 2000 hutan sekunder mempunyai luas 686,79 ha, turun menjadi 413,27 ha pada tahun 2004. Selanjutnya pada pengamatan tahun 2010 terjadi peningkatan kembali yang cukup signifikan dengan luas tutupan lahan sebesar 745,58 ha atau sekitar 14,57% dari luas keseluruhan. Peningkatan tutupan lahan hutan sekunder ini kemungkinan besar disebabkan dari hasil kegiatan reboisasi melalui program Gerakan Rehabilitasi Hutan dan Lahan (GNRHL) dan Hutan Kemasyarakatan (HKm) yang dilakukan pada tahun 2003.Kata kunci: Citra Satelit, Klasifikasi Terbimbing, Penutupan Lahan, Hutan Lindung ABSTRACTThe use of remote sensing technology in forestry sector is considered to be a proper choice for detecting land cover and land use changes fastly, cheaply and realitively cheaper. The series of satellite imageries with high spatial resolution was used to detect the land cover changes in Protected Forest Area of Reg 22 Way Waya of Central Lampung District during the last 10 years, namely 2000, 2004 and 2010. The method was used in this research is a supervised classification method. The image analysis results indicate that there were changes of each land cover type area. The secondary forest (Hs) land cover decreased about 5,2% in the period of 2004 compared to the year in 2000 (from 686.79 hectare to 413, 27 hectare). Meanwhile, the observation in 2010, the secondary forest (Hs) land cover was increased significantly against with an area of 745.58 hectares (approximately 14.57% of the total area).

Abstract

Kegiatan rumah tangga dan industri memanfaatkan sungai Bengawan Solo untuk membuang limbahnya. Hal tersebut dapat menurunkan kualitas perairan di Sungai Bengawan Solo. Perubahan kualitas perairan akan berpengaruh langsung terhadap organisme yang hidup di sungai tersebut. Keberadaan fitoplankton di suatu perairan dapat memberikan informasi mengenai keadaan perairan. Tujuan dari penelitian ini adalah untuk mengetahui struktur komunitas fitoplankton, mengetahui konsentrasi nutrien (nitrat dan fosfat) serta mengetahui hubungan kelimpahan fitoplankton dengan konsentrasi nutrien. Metode yang digunakan dalam penelitian ini adalah metode survei. Hasil penelitian ini menunjukkan bahwa komposisi jenis fitoplankton yang ditemukan selama pengamatan didominasi oleh kelas Bacillariophyceae. Genus Rhizosolenia sp., Nitzschia sp. dan Navicula sp. Kelimpahan fitoplankton pada stasiun I sebesar 2544 ind/L. Stasiun II sebesar 1975 ind/L. Stasiun III sebesar 2735 ind/L. Stasiun IV sebesar 1785 ind/L dan stasiun V sebesar 2418 ind/L. Indeks keanekaragaman fitoplankton yang diperoleh selama pengamatan di Sungai Bengawan Solo berkisar antara 1,38 – 2,22, dengan indeks keseragaman berkisar antara 0,67 – 1,07 dan indeks dominasi yang menunjukkan kisaran 0,11 – 0,20. Uji korelasi regresi antara kelimpahan fitoplankton dengan konsentrasi nutrien (nitrat dan fosfat) di perairan Sungai Bengawan Solo memiliki nilai korelasi ganda positif sebesar 0,013. Konsentrasi fosfat berkisar antara 0,59 – 1,74 mg/l. Hubungan antara kelimpahan fitoplankton dengan nitrat secara linier menunjukkan hubungan fluktuatif dengan nilai koefisien korelasi 0,277 dan koefisien determinasi sebesar 0,077 dimana 7,7% kelimpahan fitoplankton dipengaruhi oleh nitrat.  Hubungan antara kelimpahan fitoplankton dengan konsentrasi fosfat secara linier menunjukkan hubungan yang kuat dengan nilai koefisien korelasi 0,160 dan koefisien determinasi sebesar 0,025 dimana hanya 2,5% kelimpahan fitoplankton dipengaruhi oleh fosfat. Status kesuburan perairan di Sungai Bengawan Solo Kota Surakarta tergolong dalam kategori mesotrofik yaitu perairan dengan tingkat kesuburan sedang.  Household and industrial activities utilize the Bengawan Solo river to dispose of its waste. This can degrade the water quality in Bengawan Solo River. Changes in water quality will directly affect the organisms living in the river. The presence of phytoplankton in a waters can provide information about the state of the water. The purpose of this research is to know the structure of phytoplankton community, to know the concentration of nutrient (nitrate and phosphate) and to know the correlation of phytoplankton abundance with nutrient concentration.  The results of this study indicate that the composition of phytoplankton species found during observation is dominated by the Bacillariophyceae class. Genus Rhizosolenia sp., Nitzschia sp. and Navicula sp. The abundance of phytoplankton at station I is 2544 ind / L. Station II of 1975 ind / L. Station III of 2735 ind / L. Station IV of 1785 ind / L and station V of 2418 ind / L. The phytoplankton diversity index obtained during observations on the Bengawan Solo River ranged from 1.38 to 2.22, with the uniformity index ranging from 0.67 to 1.07 and the dominance index showing a range of 0.11 to 0.20. Regression correlation test between phytoplankton abundance with nutrient concentration (nitrate and phosphate) in Bengawan Solo River waters has positive double correlation value equal to 0,013. Phosphate concentrations ranged from 0.59 to 1.74 mg / l. The relationship between abundance of phytoplankton and nitrate linearly showed a fluctuative relationship with the correlation coefficient value of 0.277 and the coefficient of determination of 0.077 where 7.7% of phytoplankton abundance was influenced by nitrate. The relationship between phytoplankton abundance with phosphate concentration linearly showed a strong correlation with correlation coefficient value of 0.160 and coefficient of determination equal to 0,025 where only 2.5% phytoplankton abundance influenced by phosphate. The status of water fertility in the River Solo Solo City Surakarta classified in the mesotrophic category of waters with moderate fertility levels.
