THE EFFECT OF MANURE AND NITROGEN FERTILIZER COMBINATION ON THE GROWTH AND YIELD OF SPRING ONION IN PEAT SOIL
No full textThis study aimed to find the best combination of manure and Urea fertilizer dosage on the growth and yield of spring onions on peatsoil. This research took place from February 7 - April 8, 2019 and was located on Jalan Parit Haji Muksin II Kubu Raya. This study used an experimental method Completely Randomized Design, consisting of types of manure combined with N fertilizer consisting of 6 levels of treatment, encoded A (chicken manure + Urea 100 kg / ha), B (chicken manure + Urea 200 kg / ha), C (chicken manure + Urea 300 kg / ha), D (cow manure + Urea 100 kg / ha), E (cow manure + Urea 200 kg / ha), F (cow manure + Urea 300 kg / ha). Each treatment were repeated 4 times so that there were 24 expermental units whith 4 samples per replication so that the total of plant number were 96 plants. The observation variables in this study were plant height, number of leaves, number of tillers, root volume, leaf dry weight, root dry weight, fresh leaf weight. Observations were also made on the environmental conditions of the study, such as rainfall, air temperature, humidity. The results showed that the administration of manure and N fertilizer with a dose of chicken manure 20 tons / ha and 100 kg / ha Urea was an effective dose on the average of each observation variable of leeks on peat soil.

No full textMargaritifera sp shells can be found in the irrigation channel of Sambora Village. Clams are filter feeders groups or animals that take food by filtering water. The irrigation water flow in Sambora Village contains a substrate of muddy sand and sandy mud. This research aims to determine the morphometric characteristics and growth patterns as well as density of shells in the irrigation channel of Sambora Village, Toho Sub-district, Mempawah District. It used a purposive random sampling method. This research was conducted in March-May 2020 and the research location was divided into 3 stations. It found a total of 801 Margaritifera sp shells. All characteristics of average shell length (PC), shell height (TC), shell thickness (TBL), and total weight (BT) showed varying sizes between males and females in which the female has greater sizes than the male. The relationship between shell length and the total weight is in the range of b <3 which shows a negative allometry growth pattern. The density values ranged from 1.22 - 3.02 ind/m2. The density between stations was different with the highest at station II and the lowest at station I. The asymptotic length (L∞) of Margaritifera sp reached 126.97 mm for females and 121.42 mm for males.Keywords: Morphometric, Growth Pattern, Density, Margaritifera s

THE DIVERSITY OF HAULS OF TRAWL FISHERMEN ON FISH DISEMBARKATION IN MUARA KAKAP DISTRICT OF KUBU RAYA WEST KALIMANTAN
No full textABSTRACT It has been widely known that the Indonesian enormous fish diversity has reached over 300 species of both breams and sea breams (DKP, 2007). The diversity itself, based on LIPI (2010) has contained about 4000-6000 species all over the territorial waters. There are over 2917 species of breams identified in South East Asia (Kottelat et al 1993). This study is aimed at investigating the diversity of species of hauls of the trawl fishermen on fish disembarkation in Muara Kakap. The method of the study is purposive random sampling with random interviewee. The data was collected as primary and secondary data. The primary data was the fishermen hauls including the number and type. The secondary data was the number of regular hauls, annual hauls, decreasing hauls, the caught-hauls data from Marine and Fisheries Office of West Kalimantan Province as well as the data of rainfall and tide from BMKG. This study was conducted on March until May 2019. Based on the research findings, obtained 26 species of 21 families. 5 species of daily hauls are gelame ketupat (Nibea soldado), ikan selangat (Anodotosma chacunda), ikan gelame bungketo (Pennahia anea), ikan belanak (Mugil dussumieri). The biggest of family Scianidae were found 3 species while Lutjanidae 2 species. The diversity index during the study (H’) was 2,47 classified as average while domination index (C) was 0,12 which means none of the species are dominating.

PENGARUH PEMBERIAN KOMBINASI LUMPUR LAUT DAN PUPUK KANDANG SAPI TERHADAP KETERSEDIAAN HARA N, P, K DI LAHAN BEKAS TAMBANG BAUKSIT
No full textUltisols has an advanced degree of development, characterized by deep profil, increase of clay fraction along with the depth of soil, soil acidity, and low base saturation. Low pH, low nutrient elements such as nitrogen, phosphor, and potassium, low availability of organic carbon, Ca, Mg, Na, cation exchange capacity (CEC), base saturation are the characteristic of post bauxite mining land. The land that was formerly bauxite mining process by removing of a layer of top soil until the layer that contains the seeds of bauxite called post bauxite mining land. Coastal sediment is sediment which contains quite high micro nutrients with low CEC so by the addition of coastal sediment expected to increase base saturation and soil fertility. Cow manure is one of the alternative to improve the fertility of the soil. This study get analyzed by Complete Randomize Design (CRD) consisting of 4 treatments and 5 replications. A Treatment (control), B treatment (1.5 kg coastal sediment + 2.5 kg of manure), C treatment (2.4 kg coastal sediment + 4 kg of manure), the last D treatment (3.3 kg coastal sediment + manure). This research analyzed with the F test, if significant continued with Tukey’s Honestly Significant Difference (HSD) at the 5% level to obtain the difference between treatments. Based on the result, combination of Coastal sediment and cow manure from the C treatment (2.4 kg coastal sediment + 4 kg manure) able to increase pH of soil up to 6.68, which is the highest pH among the other treatments. Keywords : Ultisols, coastal sediment, cow manure, bauxite mining

No full textABSTRACTThe study aims to obtain the best composition of growing media for the growth of yellow pump plants plants. The research began from November 9, 2018 to January 9, 2019. The research was conducted at Jl. Purnama Agung VII, Komplek Pondok Agung Permata, Parit tokaya Village, South Pontianak. The method used was Completely Randomized Design (CRD) consisting of 5 treatments, 5 replications and for each replication there were 4 plant samples. The treatment are as follows: (m1) alluvial soil: cow manure : sand (2: 1: 1), (m2) alluvial soil: cocopeat: sand (2: 1: 1), (m3) alluvial soil: husk charcoal: sand ( 2: 1: 1), (m4) alluvial soil: cow manure: cocopeat: sand (2: ½: ½: 1) and (m5) alluvial soil: cow manure: husk charcoal: sand (2: ½: ½: 1 ) The variables observed in this study were Root Volume (cm3), Leaf Area (cm2), Fresh Weight (g) and Plant Dry Weight (g). The results shows that the composition of growing media contained cow manure provided a better for variable plant dry weight growth response compared to the composition of the growing media without cow manure.

DAMPAK BIOCHAR PLUS DAN MASA INKUBASI TERHADAP KANDUNGAN NPK TANAH GAMBUT
No full textABSTRAKBiochar merupakan produk pirolisis yang dihasilkan dari proses pembakaran dari bahan baku tertentu dengan suhu 300 – 600oC dengan suplai oksigen terbatas dan atau tanpa oksigen sama sekali. Inkubasi ditujukan agar reaksi bahan organik dan tanah dapat bejalan dengan baik, oleh karena itu perlakuan inkubasi sangat perlu diperhatikan agar nantinya unsur hara dapat tersedia bagi tanaman. Penelitian ini bertujuan untuk melihat pengaruh biochar plus terhadap sifat-sifat kimia tanah gambut pada masa inkubasi yang berbeda dan mencari masa inkubasi terbaik terhadap ketersediaan hara tanah yang diberi perlakuan biochar plus. Penelitian ini dilaksanakan di Rumah Kompos Pertanian Fakultas Pertanian Universitas Tanjungpura. Metode yang digunakan dalam penelitian ini yaitu metode pola Rancangan Acak Lengkap (RAL) dengan 6 perlakuan, masing-masing perlakuan diulang 3 kali, dan 3 jenis perlakuan decomposer sehingga jumlah polybag yang digunakan 54. Hasil menunjukkan bahwa N total tanah sebelum perlakuan yaitu 0,46 % (sedang), setelah diberikan perlakuan meningkat berkisar 1,11 (sangat tinggi). P tersedia sebelum perlakuan yaitu 12,02 ppm (rendah), setelah diberikan perlakuan meningkat berkisar 294,77 ppm (sangat tinggi). K tersedia sebelum perlakuan 0,12 (cmol (+) kg-1) (rendah), setelah diberikan perlakuan meningkat berkisar 1,20 (cmol (+) kg-1) (sangat tinggi). Perlakuan biochar plus dan masa inkubasi memberikan pengaruh terhadap sifat-sifat kimia tanah gambut. Berdasarkan hasil penelitian rata-rata statistik yang terbaik terhadap sifat-sifat kimia tanah gambut terdapat pada perlakuan P1 (Biochar Sekam Padi (750 g) + Dekomposer Beka (13,6 ml.ha-1) + Lumpur Laut (500 g) + Kompos Tankos (500 g) + NPK (300 kg.ha-1) pada masa inkubasi 4 minggu.
