Abstract

The understorey functions as a ground cover that maintains moisture so that the rapid decompositionprocess can provide nutrients for the main crop the nutrient cycle can take place perfectly, theavalanches that fall as litter will be returned to the tree in the form of nutrients which, as is known, willbe broken down by bacteria and microbes. This study aims to determine the type, number, andpresence of each understorey in the area of the Samarinda State Agricultural Polytechnic ForestManagement Study Program, precisely behind the Silviculture Laboratory. The research method useda single plot measuring 60 m x 32 m with sub plots measuring 2 m x 2 m which were arrangedsystematically so that there were 480 sub plots.The results of the study found as many as 23 speciesof understorey which were included in 22 genera, 18 families, as many as 14.616 individuals, in1.528 attendances.

Abstract

Sengon (Paraserianthes falcataria) is a plant that can grow in a wide climate distribution, but is easier to grow in the tropics. This plant has a high viability because of the root culture that plunges into and widens to the side. Even between the size of the stem and the size of the roots are almost balanced. The broad and deep root reach that causes sengon (Paraserianthes falcataria) to have a high vitality. Sengon (Paraserianthes falcataria) has a taproot. The stem is round without buttresses. The purpose of this study was to determine the average height and average diameter of sengon (Paraserianthes falcataria) trees (Paraserianthes falcataria) aged 10 years. The expected results of this research as input for the development of sengon (Paraserianthes falcataria)trees in Desa Perdana, Kecamatan Kembang Janggut, Kabupaten Kutai Kartanegara. The research method used is census namely the measurement technique carried out as a whole or 100% measurement (full enumeration). The results of measurements and calculations for the diameter, height and volume of sengon (Paraserianthes falcataria) plants aged 10 years with a spacing of 3 mx 3 m as many as 424 trees with an area of 4,000 m2 in Desa Perdana, Kecamatan Kembang Janggut, obtained the following results: minimum diameter value of 7 ,9 cm, the maximum value diameter is 27 cm and the average diameter is 17,32 cm, the standard deviation is 3,67 cm and the coefficient of variation is 21,23%, while the minimum value is 10,00 m, the maximum value is 26,32 m, and the average height is 16,78 m, the standard deviation is 2,46 m and the coefficient of variation is 14,68%, minimum volume value of 0,063 m3, the maximum value volume is 0,96m3 and the average volume is 0,299 m, the standard deviation is 0,15 m3 and the coefficient of variation is 50,29%,

Abstract

The urban forest is a community of vegetation in the form of trees and their associations that grow on city land or its surroundings. Air pollution that occurs in the urban forest reduces air quality so that its quality decreases to become unusable as it should be. The purpose of this study is to measure and identify driving noise and compare with environmental quality standards. The procedure of this research different density of vegetation from 2016-2020 has passed the Quality Standard, based on the criteria of Keputusan includes the stages of activity, namely field orientation to determine the point of Mahakam City Forest road length is 143 m, noise sampling points as many as 3 points with a distance per point is 71.5 m. The results of this study indicate that the number of vehicles passing by, the density of vegetation in the Mahakam Bridge City Forest is a factor in reducing the intensity of noise, where each measurement point has a Menteri Negara Lingkungan Hidup Nomor 48/MENLH/11/1996 tentang Baku Tingkat Kebisingan.

Abstract

Keuntungan penggunaan pestisida nabati untuk mengendalikan hama pada tanaman adalah murah, mudah, ramah lingkungan dan tidak meninggalkan residu. Penelitian ini bertujuan untuk mengetahui efektivitas penggunaan ekstrak campuran daun Sirsak (Annona muricata L.), daun Tembakau (Nicotiana tabacum L.) dan deterjen sebagai pestisida nabati terhadap pencegahan dan pemberantasan hama belalang pada semai Jati (Tectona grandis L.f.) dan mengetahui tingkat kerusakan akibat serangan hama belalang pada semai Jati (T. grandis L.f.). Penelitian dilaksanakan di Persemaian Politeknik Pertanian Negeri Samarinda. Ada tiga perlakuan yaitu kontrol, pencegahan dan pemberantasan dengan empat konsentrasi ekstrak campuran daun Sirsak (A. muricata L.), daun Tembakau (N. tabacum L.) dan deterjen sebagai pestisida nabati yaitu 0 %; 0.5%; 1.0% dan 1.5%. Hasil penelitian menunjukan pertambahan konsentrasi ekstrak campuran pestisida nabati campuran daun Sirsak (A. muricata L.), daun Tembakau (N. tabacum L.) dan deterjen berbanding lurus dengan persentase kematian hama belalang. Adapun frekuensi semai jati yang terserang hama belalang dan intensitas serangan hama belalang menunjukkan sebaliknya.

Abstract

Kandungan hara mineral pada media tumbuh dapat mempengaruhi pertumbuhan tanaman. Pemupukan merupakan cara untuk menambah kandungan hara mineral pada media tumbuh. Penggunaan Pupuk kimia dapat merusak tanah dan lingkungan. Penggunaan kompos dan teh kompos merupakan usaha alternatif penambahan hara mineral tanah yang ramah lingkungan. Penelitian ini bertujuan untuk mengetahui pengaruh pupuk organik kompos dan teh kompos dengan konsentrasi (dosis) dan interval waktu pemupukan terhadap pertumbuhan tinggi dan diameter tanaman cabai rawit. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap dengan pola Faktorial dengan 3 faktor yaitu faktor A yang terdiri dari 2 taraf (Kompos dan Teh Kompos), faktor B yang terdiri dari 3 taraf (0 gram, 150 gram dan 300 gram) dan faktor C yang terdiri dari 3 taraf (1 minggu, 2 minggu dan 3 minggu). Hasil penelitian ini adalah perlakuan jenis pupuk organik berpengaruh sangat nyata dan interaksi perlakuan jenis pupuk organik dengan interval waktu berpengaruh nyata terhadap rata-rata laju pertumbuhan tinggi dan diameter Penggunaan pupuk teh kompos ternyata menunjukkan hasil rata-rata laju pertumbuhan tinggi dan diameter tanaman cabe rawit yang lebih tinggi dari pada pupuk kompos. Interval waktu pemberian pupuk teh kompos yang berdampak baik terhadap rata-rata laju pertumbuhan tinggi tanaman cabe rawit sebaiknya 2-3 minggu sekali, sedangkan interval waktu pemberian pupuk kompos yang berdampak baik terhadap rata-rata laju pertumbuhan tinggi tanaman cabe rawit sebaiknya 1 minggu sekali.

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.
