Abstract

Chemical Character of Banana Skin Waste Liquid Fertilizer and their influences for the soya beans plant’s height. MOL is a collection of microorganisms that can be developed, which serves as a starter in the bokasi or compost production. Utilization of agricultural waste such as fruit unfit for consumption is processed into MOL could increase the added value of waste, and reduce environmental pollution (Juanda, et al., 2011). MOL utilization in organic farming is still much to do, especially soybeans. Data from the Central Bureau of Statistics According to the BPS 2013 said the soybean production in 2013 was 807 568 tons of dry beans and the amount of production is decreased when compared to production in 2012, is about 843 153 tonnes. The high consumption of soy as a feedstock would cause Indonesia still imports of processed soybean.This study was conducted from March to June 2015 lies in the Laboratory of Soil Science, Faculty of Agriculture University Mulawarman. The experimental design used completely randomized design (CRD), four replication, with doses as follows: 0 ml MOL kepok banana peel  / plant (p0 as control), 100 ml MOL kepok banana peel / plant (p1), 200 ml MOL kepok banana peel / plant (p2), 300 ml MOL kepok banana peel / plant (p3), dan  400 ml MOL kepok banana peel / plant (p4).The results showed that the content of nutrient elements in the solution is not sufficient to meet the needs of soybean plant growth, high visible from plants that are not significantly different from the control treatment. MOL solution of kepok banana peel  also not qualify on SNI liquid fertilizer.

Abstract

Penelitian ini dilaksanakan di kawasan Taman Nasional Kutai (TNK) Provinsi Kalimantan Timur. Tujuan dari penelitian ini adalah Mengetahui laju tingkat pertumbuhan tanaman pada lahan restorasi mangrove di TNK, Mengetahui hubungan kualitas lahan restorasi dengan laju pertumbuhan tanaman pada lahan restorasi mangrove di TNK, Mengetahui faktor tempat tumbuh yang berpengaruh nyata terhadap laju pertumbuhan. Lokasi penelitian terdiri atas 4 (empat) Stasiun Pengamatan yakni Stasiun Pengamatan I dan II berada di Kota Bontang dan Stasiun Pengamatan III dan IV berada di Desa Sangkima Kabupaten Kutai Timur. Penelitian ini merupakan kombinasi antara penelitian menerangkan (explanatori research) dan penelitian deskriptif (deskriptif research). Penelitian yang bersifat menerangkan adalah penelitian yang menyangkut pengujian hipotesis. Hasil penelitian ini dapat disimpulkan sebagai berikut: Pemilihan lahan restorasi sebaiknya di sesuaikan dengan jenis yang sesuai dengan tempat tumbuh. Laju bertumbuhan tanaman dipengaruhi oleh pemilihan tempat tumbuh dan terlindung dari kuat arus. Dari hasil penelitian di beberapa stasiun, kegiatan restorasi yang di lakukan di TNK sebagian tidak sesui dengan jenis tempat tumbuh tanaman

PENGARUH  PERUBAHAN  IKLIM TERHADAP POPULASI PESUT(Orcaela brevirostris) Di KALIMANTAN TIMUREffect  of Climate Change on the Fresh-Water Dolphin (Pesut) Population(Orcaela brevirostris) In East KalimantanJohansyahFakultas Pertanian, Jurusan Kehutanan, Universitas PalangkarayaPalangkaraya ABSTRACTGlobal climate change is the dynamics agent of environmental degradation, such as habitat of Mahakam Dolphin (Pesut). The degradation is very dangerous for the continuity of Pesut population life and Pesut is highly sensitive toward changes of such factor. Based on several studies conducted, today is found that population of Pesut until the year 2010 is estimated only 50 individuals, while according to Rasi (2011), it ranged 70-80 individuals. The more reduced number of Pesut population from year to year may fear, thus the extinction of this wildlife species could occurred. Some factor influencing the declining of Pesut population are the destruction of forests, changes of Pesut distribution, decreased water oxygen levels and chemical pollution of rivers.Key words : Pesut, Mahakam, Populasi, Perubahan iklim.

Abstract

The fungus in the soil naturally has a role to maintain soil function, to control its productivity and play a role in the biological control of plant-disturbing organisms. This study aims to determine the diversity of micro fungi as well as their potential as biofertilizer and biological control agents in the reclamation field of coal mines in Samarinda. This research is a descriptive research. The research was conducted in the reclamation field of coal mine of PT. CEM (Cahaya Energi Mandiri) Tanah Datar Samarinda. The research results show that there are 6 genus on 9 month reclamation field ie Fusarium, Massarina, Humicola, Rhizoctonia, Blastomyces, and Pythium. 15 genus of fungi on the 24-month reclamation field ie Mortierella, Humicola, Penicillium, Pythium, Aspergillus, Trichoderma, Blastomyces, Fusarium, Anixiella Verticillium, Gliocladium, Entomophaga, Metarhizium, Mucor, Chloridium. All genera have a role in the soil biofertilizer process, except for the unknown genus Anixiella. There are 3 genera that have the role as an insect pathogen that can be utilized in plant pest control Fusarium, Entomophaga and Metarhizium. There are 2 genera that have antagonistic role in biological control of plant disease pathogen namely Gliocladium and Trichoderma.

Abstract

Pest and Disease Identification Shorea leprosula Miq in Kutai National Park Resort Sangkima East Kutai regency of East Kalimantan Province. The purpose of this study were: (1) To determine the frequency of pest and disease types meranti Shorea leprosula Miq. (2) To determine the intensity of pests and defect types meranti Shorea leprosula Miq. (3) To determine whether or not the prevention and control of pests and plant diseases meranti types Shorea leprosula Miq. This research was conducted in the Kutai National Park Resort Sangkima East Kutai in East Kalimantan Province. This study was conducted for two months effective the month of August 2012 until September 2012.The results of the research area of 1 ha with observations census found 11 Shorea leprosula Miq trees, with one tree physically healthy, 8 mild stricken trees, one tree is being attacked, and 1 heavy stricken trees. Arise and the presence of pests and plant diseases are often referred to as crop pests on crops and forests natural forests are mostly human intervention. From the calculation of the frequency of attacks on research plots by 91%, which means that almost all types of Shorea leprosula Miq indicated no pests and diseases while 9% were healthy. From the calculation of the intensity of pests and diseases of plants Shorea leprosula Miq, including the intensity of the attack was broken by 29.5%. Based on the identification of some pests and fungal diseases like cancer, stem, leaves and termite holes. The research concluded that the frequency of pest and disease Shorea leprosula Miq by 91%, the intensity of pests and diseases of the damaged condition of the stand, including 29.5% with the intensity of the attacks, control of pests and plant diseases do not need to be done because the condition only affected stands were . Recommended based on observation of pests and diseases types Shorea leprosula Miq need for monitoring human activities that can lead to new pests and diseases in forests Resort Sangkima which can reduce the quality and growth of the forest it self.
