Abstract

The use of the main growth medium in the form of wood sawdust in mushroom domestication is still higher than that of other organic materials, even though its availability is limited, so efforts need to be made to find a growth medium composition that minimizes the percentage of sawdust use. The purpose of this study was to determine the comparison of treatment 1 (80% teak sawdust, 10% bran, 5% tapioca flour, and 5% agricultural lime) with treatment 2 (70% teak sawdust, 15% bran, 10% tapioca flour, and 5% agricultural lime) on the percentage of growth and mycelium growth of white oyster mushrooms.  Composting of growing media was carried out for 5 days, then baglog making was carried out, after which the baglog was sterilized for 4 hours. After sterilization, the baglog was cooled and inoculated. After inoculation, the baglog is incubated to grow mycelium. Then, after 15 days, data collection and calculation were carried out. The parameters measured were the percentage of growth and mycelium growth of white oyster mushrooms in baglogs. Results showed that the percentage of growth and mycelial growth of white oyster mushrooms in treatment 1 is better than in treatment 2. Reducing the percentage of the main growing medium of teak sawdust and adding the percentage of additional growing media of bran and tapioca flour has a negative impact on the number of baglogs that grow mycelium (percentage of growth) and the growth of white oyster mushroom mycelium. This means that reducing the main media of teak sawdust and adding additional media is not the right growing media composition for domestication of white oyster mushrooms, so it cannot be used as an alternative growing media composition to reduce the use of wood sawdust.

Abstract

This research is motivated by the fact that currently remote sensing technology continues to develop, both in terms of data collection and processing. This is characterized by the existence of data collection techniques using unmanned aerial vehicles for aerial photo mapping. The advantage of using this technology is that it is effective and efficient both in terms of time and human resources for mapping in areas that are not too large. Another advantage is that it can produce clearer photos, because the plane's flying height is below 400 meters above ground level so that during the shooting process there is no cloud interference. The aim of this research is to create an aerial photo map at the Samarinda State Agricultural Polytechnic, validate objects in aerial photos and in the field, and provide information about the area, boundaries and topography of the Samarinda State Agricultural Polytechnic campus area. The implementation of activities and research objects is the Samarinda State Agricultural Polytechnic campus area. This research uses a small format aerial photo mapping method using a Quadcopter, making it easier to determine where to start taking off and landing. With a Quadcopter vehicle, grounding problems are no longer an obstacle. The research results showed that photography carried out with a Quadcopter at a height of 200 m above the ground produced an area of 28.17 Ha and a spatial resolution of 8.40 cm/pixel. The validation results in aerial photos and in the field using drones have a small difference between 0-4 cm with an average of 1.625 cm/photo. From the digitization results of campus objects, there are 30 objects on campus with a total area of 2.67 Ha. As for the topography results in the campus area, the highest point is 107.5 meters above sea level and the lowest point is 60 meters above sea level.

Abstract

The existence of weeds on agricultural land causes competition with cultivated plants in obtaining nutrients, water, and sunlight. Therefore, it is necessary to carry out weed control so as not to interfere with the growth and development of cultivated plants. This study aims to find out the types of weeds that grow in the disc area and to find out the most effective herbicides based on the content of active ingredients in controlling weeds in the oil palm disc area. Sampling was carried out by purposive sampling technique. Based on this technique, 2 blocks were obtained as research locations, namely block 73B and block 68A with a sample area of 351 m2 in each block. In this area, 9 sample plots were made with the size of each plot 1 m x 1 m. The object of the study was in the form of weeds in the sample plots that were given different treatments, namely using a single herbicide using a Kenfosat herbicide with the active ingredient isopropyl amine glyphosate with a dose of 2 liters/ha in block 73B and a mixed herbicide consisting of a Kenfosat herbicide with the active ingredient isopropyl amine glyphosate + Mitsufuron herbicide with the active ingredient methyl metsulfuron + agristick with the active ingredient alkyllaril polyglycol ether with a dose of 2 liters/ha + 0 each, 075 gr/ha + 0.1 liters/ha in block 68A. The results showed that the types of weeds that grew in the oil palm disk area were broad-leaved weeds such as Ageratum conyzoides, Asystasia intrusa, Clidemia hirta, Phyllanthus urinaria and narrow-leaved weeds such as Setaria plicata. Based on the content of the active ingredient, the most effective herbicide in controlling weeds in the oil palm disc area is a mixed herbicide because it is able to kill weeds completely (100%) on the 15th day after the herbicide application.

Abstract

This research is motivated by the fact that the natural forest in the miniature block area of PT. Timberdana is covered with various types of vegetation which is used as an educational forest area, research and a place for sustainable development. This area does not yet have a tree distribution map which can later be used as information for sustainable management. So the aim of this research is to identify the type, number of trees, coordinate the trees, and create a map of the distribution of trees in the PT miniature block area. Timberdana and identify its spatial distribution patterns. The research method involves field surveys to identify tree types, coordinate trees, and collect data on trees in the miniature block area. Measurement and identification of tree species is done with the help of botanists and appropriate reference guides. The collected data was analyzed using spatial analysis and mapping techniques using GIS (Geographic information system) software for data processing to visualize the distribution of tree species and identify their spatial distribution patterns. The results of the research show that there are many species of natural forest trees that are quite tall in the PT miniature block. Timberdana. The trees in the block area consist of 17 types with a total of 401 trees from 7 families. Based on the results of mapping the distribution of trees in the miniature block area of PT. Timberdana's spatial distribution pattern is random. This shows that random distribution patterns tend to be safer for plant management efforts

Abstract

Penelitian ini bertujuan untuk mengetahui kondisi hutan pada wilayah Kabupaten Nunukan khususnya pada wilayah hutan Pulau Nunukan dan Pulau Sebatik. Berdasarkan tujuan tersebut, penelitian ini diharapkan dapat dijadikan sebagai acuan atau dasar dalam penentuan kebijakan pengelolaan hutan di wilayah Kabupaten Nunukan Provinsi Kalimantan Utara. Penelitian dilaksanakan di Pulau Nunukan dan Pulau Sebatik selama 3 bulan, yaitu mulai bulan Juli sampai dengan bulan September 2021. Penelitian dilakukan secara purposive sampling dengan membuat plot penelitian sebanyak masing-masing 3 (plot). Untuk pengamatan tingkat pohon digunakan plot berukuran 10 m x 10 m, tingkat tiang digunakan plot berukuran 10 mx 10 m, untuk tingkat pancang digunakan plot berukuran 5 m x 5 m dan untuk tingkat semai digunakan plot berukuran 2 m x 2 m. Parameter vegetasi yang didapat di lapangan, diolah untuk mendapatkan Indeks Nilai Penting antara lain jenis, kerapatan (K), frekuensi (F), dan dominansi (D). kemudian untuk mengetahui keanekaragaman jenisnya digunakan Indeks Shannon-Wiener. Hasil pengolahan data dianalisis secara deskriptif. Disimpulkan bahwa hutan di pulau Nunukan dan pulau Sebatik memiliki keanekaragaman jenis yang rendah dan hanya meranti merah (Shorea leprosula) yang hadir di empat fase pertumbuhan. Rendahnya keanekaragaman jenis ini tidak terlepas dari pemanfaatan hutan sebelumnya, yaitu pembalakan hutan yang tidak terkontrol. Perlu pengawasan yang intensif terhadap hutan yang masih tersisa agar tidak ada gangguan lagi dan proses suksesi bisa berjalan dengan baik. Perlu pengayaan jenis komersial terutama pada daerah yang terbuka.
