Abstract

Gulma merupakan tumbuhan yang merugikan kepentingan manunsia. Penelitian bertujuan untuk mengevaluasi pengaruh herbisida atrazin dan mesotrion serta campurannya terhadap gulma Echinochloa colona. Penelitian dilakukan di Kebun Percobaan dan Laboratorium Pestisida Fakultas Pertanian, Universitas Tanjungpura, Pontianak pada September November 2019. Penelitian dilaksanakan menggunakan Rancangan Acak Kelompok. Herbisida yang digunakan atrazin, mesotrion dan campurannya. Perlakuan setiap herbisida terdiri dari 5 taraf dosis, ditambah kontrol, dengan 5 ulangan pada setiap perlakuan. Itensitas keracunan gulma dan data bobot kering gulma diamati. Analisis probit mengunakan untuk aplikasi SAS. Herbisida mesotrion dengan dosis 0,63 1/ha, 1,25 1/ha dan 2,5 1/ha dapat menghambat pertumbuhan gulma Echinochloa colona, tetapi tidak dapat membunuh gulma secara tuntas. Penggunaan herbisida atrazin lebih baik dibandingkan herbisida mesotrion.

Abstract

Celery plants (Apium graveolens L.) which are cultivated in peat soils face several obstacles such as soil acidity and deficiency of nutrients. Palm fruit bunches ash has an important role to improve pH in soils. Whereas this plants needs N, P and K fertilizers for growth and development. The purpose of this research was to investigate the best interaction between palm fruit bunches ash dosage and N, P and K fertilizer on the growth and yield of celery in peat soils. This research was conducted at the research house of the Faculty of Agriculture, Tanjungpura University, Pontianak, lasted from 16 December 2018 to 14 March 2019. This research used a Factorial Complete Randomized Design method consisting of 2 factors with 3 treatments each, 3 replications and 4 plant samples each treatment. The first factor is the provision of palm fruit bunches ash, called: a1= 4.5 tons/ha, a2 = 6 tons/ha, and a3 = 7.5 tons/ha. The second factor called: p1 = 50% recommended dosage of Urea (75 kg/ha, SP-36 25 kg/ha and KCl 50 kg/ha), p2 = 75% recommended dosage (Urea 112.5 kg/ha, SP-36 37.5 kg/ha and KCl 75 kg/ha), and p3 = 100% recommended dosage, (Urea 150 kg/ha, SP-36 50 kg/ha and KCl 100 kg/ha). The observed variables were root volume (cm3), number of leaf stalks, number of tillers, plant fresh weight (g), and plant dry weight (g). Interaction occurred between oil palm long ash and fertilizer N, P and K on the variable number of tillers, while the variable root volume, number of leaf stalks, fresh weight, and plant dry weight did not occur. Results of this research found an effective of palm fruit bunches ash dosage 4 tons/ha and N, P and K fertilizer with 50% dosage recommended (75 kg/ha, SP-36 25 kg/ha, and KCl 50 kg/ha). Key word : Celery, N, P and K fertilizer, palm fruit bunches ash, peat soil

Abstract

Buah mengkudu segar mengandung banyak nutrisi, komponen aktif dan memiliki kadar air tinggi. Tingginya kadar air mengakibatkan masa simpan yang singkat, sehingga perlu dilakukan proses pengeringan. Pengering adsorpsi dengan menggunakan adsorben berfungsi untuk menurunkan kelembaban mutlak udara. Penurunan kelembaban ini dapat meningkatkan kemampuan udara untuk menguapkan air sehingga efisiensi pengeringan dapat lebih tinggi. Penelitian ini bertujuan untuk melakukan pengujian performansi pengering sistem adsorpsi berdasarkan jumlah dan suhu pengeringan irisan buah mengkudu. Irisan mengkudu yang digunakan sebanyak 7 kg dan 14 kg dan suhu pengeringan yaitu 50 C, 57C dan 65 C. Parameter yang diamati yaitu berat bahan, suhu, energi listrik dan kecepatan aliran udara. Alat pengering kabinet sistem adsorpsi ini memiliki performa terbaik pada suhu 50 C dan 14 kg irisan mengkudu dengan efisiensi termal sebesar 36,6% dan efisiensi total sebesar 26,5% dengan total waktu pengeringan 27 jam.

Abstract

The cultivation of cayenne pepper in alluvial soil has some problems, one of them is the solid structure of the soil. Poultry manure can be used as an alternative to soil structure, while mulch to reduce nutrient leaching from rain splashes. This study aims to find out the interaction of poultry manure and mulch on the growth and yield of cayenne pepper plants on alluvial soil. This research was conducted in Tengguli village land, Sajad District, Sambas Regency from 18th February to 15th May 2019. This study used a split plot design, is silver plastic mulch (m0= without mulch and m1= mulch) as main plot and poultry manure (a1= 5 ton/ha, a2= 10 ton/ha, a3= 15 ton/ha) as sub plot. Observation variables were plant height, dry weight of the plants, root volume, number of plant fruit, weight of plant fruit, weight of fruit, number of plot fruit, and weight of plot fruit. The result shows that the interaction poultry manure 15 to/ha  and mulch provide  the highest of growth and cayenne pepper plant results on alluvial soil. Keyword: Mulch, Poultry Manure, Alluvial Soil, Cayenne Pepper Plants.

Abstract

The most obvious peat land conversion nowadays is the conversion of peatlands for plantations and the palm oil industry. As a result of the land clearing activities in large-scale in peat soil, it caused peat land damage. Peatland degradation in Rasau Jaya district today can be seen from the changes in physical properties of peat soil. A real change of physical properties of peat soil today is the peat layer depletion due to drainage, and low power of loadbearing structure of the soil, so many palm trees grow sideways. The research objective was to identify changes in physical properties of peat soil of secondary forests, open land, and oil palm plantations.Soil samples were collected from study sites in kubu raya district of  west Kalimantan. Parameters include water table in each site and in secondary tunnels, field capacity water content, bulk density, particle weight, porosity, hydraulic conductivity, and soil maturity levels. The results showed that water table was deeper in temporarily open land (66,35 cm) and in oil plam plantation (64, 0 cm), and shallow in secondary forest (54,26 cm). Water table at secondary tunnels was also deeper in temporarily  open land (109 cm), higher in oil plam plantation (100, 5 cm), and highest in secondary forest (99,25 cm). Field capacity  content was highest in secondary forest (79,65%), lower in temporarily open land (77,62 %), and lowest in oil palm plantationnn (75,41 %). Furthermore, bulk density was highest in oil palm plantation (0,46 g/cm3),lowest in temporarily open land (0,27 g/cm3), and  lower ini seconday forest (0,22 g/cm3). Particle weight was also highest in oil palm plantation (1,59 g/cm3), lower ini temporarily open land (1,34 g/cm3), and lowest in secondary forest (1,26 g/cm3). Meanwhile, porosity was lowest in oil palm plantation (70,92 %), higher in temporarily open land (78,94 %), and highest in secondary forest (81,80 %). Hydraulic conductivity was also highest in oil palm plantation (10,61 cm/hour), lower in temporarily open land (7,88 cm/ hour), and lowes in secondary forest (5,23 cm/hour). Finally, there were vary in soil maturity levels, namely hemik and fibric in seconday forest, hemic, fibric, and sapric in temporarily open land, and only sapric in oil palm plantation. Conclusion, different management types had caused changes in soil physical properties of peatland.
