PENGARUH PUPUK MAJEMUK TERHADAP PERTUMBUHAN dan HASIL TANAMAN BAWANG MERAH pada TANAH GAMBUT
No full textBawang merah (Allium ascalonicum L.) merupakan salah satu jenis tanaman hortikultura multifungsi yang memiliki nilai ekonomis cukup tinggi. Tanah gambut berpotensi untuk perluasan areal budidaya tanaman bawang merah. Pemanfaatan tanah gambut sebagai media tanam tanaman bawang merah dihadapkan pada beberapa kendala terutama sifat kimia dan kandungan unsur hara yang rendah. Alternatif untuk menyediakan unsur hara bagi tanaman pada tanah gambut yang kurang akan unsur hara yaitu dengan menambahkan bahan pupuk majemuk berupa NPK mutiara. Penelitian ini bertujuan untuk mendapatkan dosis pupuk majemuk yang terbaik bagi pertumbuhan dan hasil tanaman bawang merah pada tanah gambut. Penelitian ini dilaksanakan selama 3 bulan yaitu dari tanggal 14 Juli – 14 Oktober 2017 di kebun percobaan Fakultas Pertanian Universitas Tanjungpura Pontianak. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dengan 5 ulangan dan tiap ulangan terdiri dari 3 tanaman sampel. Perlakuan yang dimaksud adalah pemberian pupuk majemuk NPK mutiara dengan dosis 0,8, 1,6, 2,4, 3,2 dan 4 g/tanaman. Variabel yang diamati dalam penelitian ini meliputi tinggi tanaman, jumlah daun, jumlah umbi per rumpun, berat segar umbi per rumpun, berat kering angin umbi per rumpun. Hasil penelitian menunjukkan bahwa pemberian pupuk majemuk NPK mutiara dengan dosis 0,8 g/tanaman merupakan dosis yang terbaik dibandingkan dengan dosis lainnya.

STUDY OF PHOSPHATE SOLUBILIZING FUNGI IN PEAT SOIL IN SEVERAL TYPES OF LAND USE OF SIANTAN HILIR VILLAGE PONTIANAK CITY
No full textThe use of peat land for agriculture is growing rapidly. However, in this utilization various problems were encountered, one of which was the strength of phosphate nutrients. One alternative to overcome the low availability of phosphate is to use a phosphate solvent fungus. This study aims to determine the population and type of phosphate solubilizing fungus and the population differences in several peatland uses (oil palm, pineapple, mustard, aloe, papaya and secondary forest) and to know the ability of fungi to dissolve phosphate nutrients. The methods used in this study are preparation, selection and observation of the location of the study, determination of sampling points, soil sampling (microbiology specific soil samples, sample samples and disturbed soil samples), preparation and sterilization of equipment and media in the laboratory, calculation and isolation fungus phosphate solubilizing colonies. The results showed that the highest population of phosphate solubilizing fungus (CPF) was found on pineapple land which was as much as 2.99 x 104 CFU / ml, and the lowest on aloe vera land was 2.11 x 104 CFU / ml. The analysis of the diversity of CPF population numbers on six land uses showed that the number of CPF populations had no significant effect. The types of fungi found were 13 types of solubilizing fungi. The land use which has the most phosphate solvent fungus types is oil palm and pineapple land. The ability of the fungus to dissolve phosphate can be seen from how large the clear zone is formed. Land use which has the largest area of clear zone is found in oil palm land which is equal to 242.31 mm2 and the smallest on pineapple land which is equal to 118.74 mm2. The test results of the analysis of the wide diversity of clear zones on aloe vera, papaya, mustard, oil palm, pineapple and secondary forest showed that the area of clear zones had no significant effect on land use. The land use system influences the diversity of phosphate solubilizing microorganisms and the ability to dissolve phosphate but the land use system does not affect the population of phosphate solubilizing fungi.

Exploration Of Filosphere Bacteria As Agents Biocontrol Anthracnose Disease Colletotrichum musae (Berk and Curt) Arx On Banana Fruit
No full textABSTRACTColletotrichum musae (Berk. and Curt.) Arx. is a pathogen that causes anthracnose on bananas. Biocontrol agents is one of the alternatives to reduce negative impact of pesticide. This study aims to explore the phylosphere bacteria in bananas which are potential as antagonists to C. musae. The study was carried out at the Laboratory of Plant Diseases, Faculty of Agriculture, University of Tangjungpura Pontianak from November 2017 to April 2018. The bacterial isolates obtained were tested for antagonistic potential against C. musae by dual culture, conidial viability test C. musae and ability to lyse the hyphae. Hypersensitivity testing of bacterial isolates which have the potential as biological agents carried out on tobacco plants. The results of isolation of phylosphere bacteria obtained 16 bacterial isolates. Based on the testing, 3 isolates NPOB1, BPNB1 and BPNB3 have great potential as a antagonists to C. musae. According to antagonistic test, bacterial isolates had an inhibition between 51,84%-65,18%. The inhibition of conidia germination was 4,85%-39,4%. The ability of chitinolytic enzymes produced was 12,43%-31%. Sixteen phylosphere bacteria isolates were not plant pathogenic based on HR tests on tobacco leaves.

This research was conducted in Seguri forest located at Desa Peniti, Entada forest in Desa Gonis Tekam and Munggu Betung forest in Desa Semabi for three months, started from December 2017 until March 2018, using survey method by exploring all of the Tembawang Seguri forest areas and Tembawang Entada forest. The sampling was done by purposive sampling. The criteria of the mature plants and plant that has been fruitful several times. Based on the result of the research in the field, there are six types of Durian, the six types of Durian are Durio zibethinus, Durio kutejensis, Durio oxleysnus, Durio lanceolatus, Durio lowianus and Durio excelcus. The type of Durio zibethinus Murr was the most widely plant found in Entada,Seguri and Munggu Betung forest. Durio lanceolatus only found in Entada forest. Durio lowianus was found in the Entada and Munggu Betung forest and Durio exelcus was found in Seguri and Munggu Betung forest. Generally, the place of Durian plant not really different in each species, based on the vegetation, the condition of environment. The difference was only in the height of the place and habitat, and even it was still in a condition that the durian plant wants to grow. There were no specific species found of Durian in the others location because the trees was cut down by the villagers because of the unpleasant taste of the fruit, the conversion of land functions such as agriculture, house building infrastructure and others, and lack of public awareness of biodiversity conservation.

ANALYSIS OF SUSTAINED RICE RECEIVER CUSTOMER SATISFACTION IN SANDAI DISTRICT KETAPANG DISTRICE
No full textThe purpose of this study was to analyze the level of customer satisfaction recipients of subsidized rice in Sandai District, Ketapang Regency. The samples used in the study were as many as 100 respondents selected by the purposive sampling method. Data were collected using questionnaires then analyzed by Importance Performance Analysis (IPA) using SPSS 20. Software Important Performance Analysis was used to determine the relationship of importance and performance assessment of the quality of services provided by officers, so they could know what attributes should be improved , maintained, corrected and eliminated or evaluated. Then analyzed again with the Customer Statisfaction Index (CSI) using Microsoft Office Excel to determine the level of customer satisfaction. The results of this study indicate that recipients of subsidized rice are satisfied with the distribution of subsidized rice in Sandai Sub-District, Ketapang District, but it is expected that officers can continue to increase the satisfaction of consumers receiving subsidized rice.
