Abstract

Identification of various types of land cover in the Air Telang Protected Forest has been carried out during the period 1989-2013. The method used in identifying the dynamics of land cover in this area is the survey method of land cover changes based on time series remote sensing data in 1989, 2001 and 2013. Analysis of data in this study was in the form of analysis of land cover changes in Air Telang Protected Forest using GIS with a two-period overlay of time series technique namely the period 1989-2001 and 2001-2013. The results showed that there were around 55.11% (6,978.00 ha) of primary forest that still survived during period 1 (1989-2001) and around 44.8% (5,671.53 ha) in period 2 (2001-2013). The area of primary forest increases because of the succession of several types of land cover, such as secondary forests, coconut plantations, swamp shrubs, ponds and water bodies into primary forests. The reduction in primary forest area is caused by the conversion of forests by communities into coconut plantations, oil palm plantations and ponds, and illegal logging. The Air Telang Protected Forest area needs to be restored in an effort to maintain its function as a protected forest. Keywords: overlay of time series, Air Telang Protected Forest, dynamics of land cover ABSTRAK Identifikasi berbagai tipe tutupan lahan di Hutan Lindung Air Telang (HLAT) telah dilakukan selama periode tahun 1989-2013. Metode yang digunakan dalam mengidentifikasi dinamika tutupan lahan di wilayah ini adalah metode survey terhadap perubahan tutupan lahan berdasarkan data penginderaan jauh multitemporal tahun 1989, 2001 dan 2013. Analisis data dalam penelitian ini berupa analisis perubahan tutupan lahan di HLAT menggunakan GIS dengan teknik overlay multitemporal dua periode yaitu periode tahun 1989-2001 dan 2001-2013. Hasil penelitian menunjukkan bahwa ada sekitar 55,11% (6.978,00 ha) hutan primer yang masih bertahan selama periode 1 (1989-2001) dan sekitar 44,8% (5.671,53 ha) pada periode 2 (2001-2013). Luas hutan primer bertambah karena adanya suksesi beberapa tipe tutupan lahan, seperti hutan sekunder, kebun kelapa, belukar rawa, tambak dan badan air menjadi hutan primer. Sedangkan berkurangnya luas hutan primer disebabkan karena adanya konversi hutan oleh masyarakat menjadi perkebunan kelapa, perkebunan kelapa sawit dan tambak, serta penebangan hutan secara liar. Kawasan HLAT perlu direstorasi dalam upaya untuk mempertahankan fungsinya sebagai hutan lindung. Kata Kunci: overlay multitemporal, Hutan Lindung Air Telang, dinamika tutupan lahan

Abstract

Research on the Consumption Preference for Rice Beetles (Sitophilus oryzae L) in Several Rice Varieties was carried out from March to Mei 2019 at Laboratory Science Center of PGRI University. The study aims to determine the consumption preferences of several rice varieties caused by rice beetles. The study used the Experimental method in a completely randomized design (CRD) with five treatments and five replications, namely white, red, black, white sticky rice and black sticky rice varieties. Based on the analysis of fingerprints, the treatment of white sticky rice varieties significantly affected the amount of lose weight rice and rice beetle consumption preference, then continued with the BNT Test. The treatment of varieties D (white sticky rice) was not significantly different from the treatment of varieties E (black sticky rice), treatment E (black sticky rice) significantly different from the treatment of variety C (black rice), the treatment of variety C (black rice) was not significantly different from the treatment of variety B (brown rice), treatment of variety B (brown rice) was significantly different from the treatment of variety A (white rice). Based on the BNT Test, rice beetle consumption preferences seen from the weight reduction of rice in D rice varieties had the greatest weight reduction of 6.6 grams and the lowest weight reduction was white rice varieties of 0.9 grams, while for red, black and Black sticky rice has an average weight loss of rice each of 4.1 grams, 4.2 grams and 5.7 grams. Based on the percentage of preference (preference) for rice beetle consumption, it was found that the highest percentage was found in white sticky rice varieties at 6.6% and the lowest in white rice varieties at 1.5%, while for brown rice varieties at 4%, black rice 4.2% and black sticky rice 5.6%.

Abstract

Research on the types of orders of Passeriformes that have been traded at the Palembang bird market in South Sumatra has been carried out. The aim of this study was to find out the types of Passeriformes sequences, including endemic birds, protected birds and endangered Sumatran birds that were traded at the Palembang bird market. South Sumatra. This research was conducted in January-April 2019, at the bird market on the old Masjid Jalan, Kelurahan 17 Ilir and Pasar Cinde on Jalan Jendral Sudirman. The method used is purposive sampling. Bird identification was carried out at the Biology Laboratory, Faculty of Mathematics and Natural Sciences, University of PGRI Palembang. The types of Order Passers found were 12 Familia, 23 Genus, and 31 Species. Familia Sturnidae which has the highest diversity of species, namely 5 species.
