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

Fokus kebijakan energi selama ini hanya memperhatikan sektor Supply Side Management (SSM), sedangkan penerapan konservasi energi Demand Side Management (DSM) belum dilakukan secara maksimal. Tujuan penelitian ini untuk mengetahui proyeksi permintaan energi listrik rumah tangga di Yogyakarta tahun 2010 hingga 2025 berdasarkan penggunaan peralatan listrik, pertumbuhan rumah tangga, serta penerapan konservasi pada peralatan listrik. Penelitian ini menggunakan metode yang disebut BUENAS (Bottom Up Energy Analysis System) dengan mengambil sampel 269 rumah tangga di Yogyakarta secara cluster random sampling. Data konsumsi peralatan listrik kemudian digunakan untuk memprediksi kebutuhan listrik kota Yogyakarta tahun 2010 hingga 2025 menggunakan perangkat lunak LEAP (Long range Energy Alternatives Planning System). Proyeksi yang dilakukan berdasarkan pendekatan end-use dan pendekatan trend dengan kecenderungan pertumbuhan jumlah rumah tangga.

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). The increase of the secondary forest cover is most likely caused by the reforestation program of the Forest and Land Rehabilitation Activity (GNRHL) and Community Forestry in 2003.Keywords: Satellite Images, Supervised Classifications, Land Cover, Protected Forest

Abstract

ASEAN Community 2015 became one of its own products made by ASEAN leaders to ease the creation of a variety of access both in the economic, political, social, cultural, defense and security. Within the ASEAN Community 2015, becoming one of its own steps to open markets more freely so that the movement of the mobility of goods and services can be channeled properly not only in the country in each of the ASEAN countries, however, can be transferred to all other countries. One of the constraints in this regard is how the readiness of the government of a country in ASEAN to face of fierce competition that will take place freely and openly among various countries so that if not handled properly can result in a fairly high unemployment because the foreign labor which is presented in one of the ASEAN countries is a labor that has a high skill. Therefore, the government must also concern related to the brain circulation phenomenon are able to strengthen the various sectors where the government is able to provide its own facilitieswith the provision of the allocation of funds for research and development and create policies that ensure the products to the convenience of skilled labor to carry out research in homeland then it will strengthen the stability of labor market in ASEAN.
