Abstract

Basal stem rot (BSR)  caused by white decay fungus, Ganoderma boninense is known to cause significant losses in oil palm plantation in Southeast Asia. This study determined the effect of oil palm mixed planting with rhizomatous plants, galangal (Alpinia galangal), Java curcumin (Curcuma longa), or ginger (Zingiber officinale) on initial infection of BSR. Plants were inoculated by attachment of rubber wood block colonized with G. boninense to the main roots. Infection was measured as length of root necrosis and confirmed by culturing on Ganoderma selective medium. Infection was also assessed by total activity of ligninase as measured by RBBR decolorization. The results showed that G. boninense infection at 1-month-post inoculation was lower on mixed planting with all rhizomatous plants, and the suppression of infection was still occured in mixed planting with galangal. Total activity of ligninase on oil palm roots was delayed on mixed planting compared to that of higher activity on single planting at 1-month-post inoculation. This result highlights benefit of mixed planting of oil palm with  rhizomatous plants in delaying initial infection of BSR patogen.

Abstract

Pestisida adalah zat khusus untuk memberantas, mencegah atau membasmi gangguan serangga, binatang pengerat, nematoda, cendawan, gulma, virus, bakteri, jasad renik yang dianggap hama yang merugikan. Penggunaan pestisida yang berlebihan dapat menyebabkan resistensi hama, resurjensi hama, munculnya hama sekunder, dan pencemaran lingkungan. Penelitian ini bertujuan untuk melakukan evaluasi penggunaan pestisida oleh petani dalam mengendalikan hama dan penyakit pada pertanaman hortikultura di Kabupaten Bangka, Provinsi Kepulauan Bangka Belitung. Penelitian ini disusun berdasarkan wawancara dan hasil observasi pada lahan pertanaman petani hortikultura. Hasil yang didapatkan dari wawancara dan observasi tersebut menunjukkan bahwa petani masih banyak menggunakan pestisida sintetik dengan tidak bijak dalam mengendalikan hama dan penyakit tanaman yang dibudidayakan. Dalam penggunaan pestisida, petani masih mengandalkan pengalaman pribadinya dibandingkan dengan ilmu pengetahuan. Rata-rata petani belum memahami penggunaan pestisida yang baik dan benar sehingga tidak mengerti mengenai ambang ekonomi dalam menggunakan pestisida. Kesimpulannya, petani masih beranggapan bahwa semakin banyak jenis pestisida yang digunakan, maka semakin cepat untuk mengendalikan hama dan penyakit tanaman. Dengan demikian, perlu adanya penyuluhan tentang penggunaan pestisida pada petani, sehingga petani dapat memahami cara penggunaan pestisida dengan bijak untuk kedepannya. Spesies hama dan penyakit yang menyerang tanaman hortikultura yaitu, 13 spesies hama dan 11 spesies penyakit.

Abstract

Livestock waste becomes a problem and disturbs the community environment. In addition to the odor generated, it causes an unclean environment. Livestock waste is a problem for the people of Jungkal Village, Pampangan District, Ogan Komering Ilir Regency, South Sumatra. Good environmental management must be a priority. Therefore, livestock waste must be utilized to create a healthy environment. The purpose of this activity was to explain the use of livestock waste as a medium to produce bio-insecticides made from the active Bacillus thuringiensis bacteria. The target community was a farmer group in Jungkal Village. Activities were carried out in two ways, namely socialization activities and practical activities to produce bio-insecticide with active B. thuringiensis. Preliminary data showed that farmers were aware that livestock waste causes discomfort. Handling both liquid and solid waste has yielded little results because, so far, farmers have only gotten rid of this waste without using it as a helpful product. After the community service activities were completed, 80% of the participants understood the benefit of livestock waste. With an intensive approach and assistance, farmer groups can receive new directions.

Abstract

Corn (Zea mays L.) is one of the most important food crop commodities in the world after rice and wheat. In some countries, corn is the main source of carbohydrates. However, pests and diseases are the main obstacles to maize production in the tropics and sub-tropics. There are two main diseases that have the potential to reduce maize production, including leaf rust and leaf blight. leaf rust disease can reduce production up to 70% Leaf rust disease is caused by Puccinia Sp. Leaf blight can cause yield losses of up to 50%. Leaf blight is caused by Helminthosporium turcicum. Therefore, combined control is needed to minimize the impact, namely by applying the concept of integrated disease management. This study aims to determine evaluate integrated disease control that has been carried out by several farmers in Suka Menang village, Gelumbang District, Muara Enim Regency. The results of field practice show that most of the corn farmers in Suka Menang Village, Glummbang District, Muara Enim Regency have implemented the concept of integrated disease management. In the implementation process, farmers are not aware that what they are doing is included in the control. There are 2 types of diseases that attack corn plants, namely, Puccinia sp. and Helminthosporium turcicum.
