Herbicide mixing technology is an opportunity to improve efficiency and control weeds. This study aimed to develop the effectiveness of a mixed herbicide (tank mix) between the active ingredient formulations of tiafenacil, glyphosate, methyl metsulfuron, and paraquat dichloride in controlling common oil palm weeds. The research was carried out for approximately 3 months, from January to March 2021, in oil palm plantations. The research used was a randomized block design with 9 treatments and 4 replications. Herbicide application using a knapsack sprayer and a red nozzle. Spraying is carried out on weeds in the oil palm weed circle. Vegetation analysis was carried out before the application of herbicides, the percentage of mortality was observed 3,7, 14, 21, and 30 days after spraying and weed regrowth was carried out 30, 45, and 60 days after spraying. The results showed that the paraquat mixture of tiafenacil was able to increase the effectiveness of the herbicide against common weeds compared to the single herbicide tiafenacil at doses of 2 l/ha and 4 l/ha based on mortality. The paraquat mixture in methyl metsulfuron was able to increase the effectiveness of the herbicide against common weeds compared to the single herbicide methyl metsulfuron based on its mortality. The single herbicide tiafenacil dose of 2 l/ha was able to suppress the dry weight of Ottochloa sp better than the single herbicide tiafenacil dose of 4 l/ha. The mixture of methyl metsulfuron in tiafenacil was able to suppress the dry weight of Asystasia sp better than the single herbicide tiafenacil at a dose of 2 l/ha.

Performance Study of Independent Small Holder Oil Palm Plantation at Kubu Raya Regency. Independent small holder oil palm plantations are small holder oil palm plantations that are not affiliated with any institution. Farmers sell their own produce to local mills directly or through traders. Independent oil palm smallholders are faced with various problems, including limited access to information technology sources, financing, and markets. Independent small holder oil palm plantations in Kubu Raya Regency are facing a bigger problem because most of the plantations are on peatlands, therefore efforts are needed to help these farmers. Efforts that need to be made at this time are the provision of a database of independent small holder oil palm plantations, which so far do not exist. This study aims to obtain data on the performance of independent small holder oil palm plantations in Kubu Raya Regency. Collecting data using the interview method with a questionnaire. The results showed that most of the independent small holder oil palm farmers in Kubu Raya Regency running their business only as a side job so that the management is not optimal. Another obstacle is the difficulty in accessing the market so they are forced to sell their fruit through middlemen. The problem of transportation, namely transportation and inadequate roads, is also one of the causes of the difficulty in marketing the fresh fruit bunch.

This study aims to determine the effect of tillage on the amount of deposits of weed seeds in the soil on alluvial soil. Research conducted at the Faculty of Agriculture experimental field Tanjungpura in August to December 2014. Identification and data processing carried out at the Laboratory of Plant Pests Tanjungpura University . Research using observation method with weeds growing vegetation analysis after tillage. Observations were made after 1 times tillage , 2 times , 3 times and 4 times. Results of this study indicate that there are five species of weeds that have the highest amount of seed bank with a value of SDR above 10 % and is considered an important weed that is, Borreria alata, Cyrtococcum sp, Ageratum conyzoides, Ludwigia parennis and Phyllantus debilis. Based on the results of this study concluded that as many as 1 times tillage can reduce the weed seed bank in the soil deposits if done before the weeds produce seeds.

Kalimantan Barat merupakan salah satu provinsi penghasil lada di Indonesia. Luas tanaman lada sejak 2002-2007 terjadi penambahan lahan, namun tidak berdampak pada peningkatan produksi, karena salah satu penyebabnya banyak tanaman terinfeksi hawar beludru. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang berpengaruh terhadap keparahan penyakit hawar beludru pada tanaman lada. Metode yang digunakan dalam penelitian ini adalah survei dengan pengamatan secara langsung terhadap keparahan dan perkembangan penyakit. Data primer didapat melalui pengamatan langsung di lapangan, data sekunder diambil dari kuesioner pada 25 petani. Variabel yang diamati adalah keparahan penyakit dan perkembangan penyakit, serta faktor budidaya yang diterapkan petani. Hasil penelitian menunjukkan dari 9 faktor epidemik yaitu : umur tanaman, system tanam, jenis tajar, lokasi pembibitan, tingkat produksi, jenis pupuk yang digunakan, frekuensi pemupukan, pemakaian, insektisida, pemakaian fungisida, pemangkasan tanaman, drainase pada kebun, terdapat 4 faktor budidaya yang mempengaruhi perkembangan penyakit hawar beludru, yaitu: 1. umur tanaman (tanaman menghasilkan), 2. sistem tanam (tanaman tumpang sari), 3. jenis tajar (tajar mati), 4. frekuensi pemupukan (frekuensi pemupukan 1 kali pertahun). Kata kunci : faktor budidaya, hawar beludru, tanaman lada
