Abstract

Bioactivity Test of Zodea Leaf Extract (Evodia suaveolens Sheff) on Red Flour Beetle Tribolium castaneum(Coleoptera: Tenebrionidae)Herbst.The study bioactivy of zodea leaf extract on red flourbeetlewas conducted in Laboratory of Entomology, Plant Pest And Disease Department, Faculty of Agriculture, Sriwijaya Universityfrom June to September 2014.E. suaveolensis a native plant from Papua that very well-known as mosquito repellent. The experiment aimed to determined level of repellent various extract concentrations of zodea leaf extract and mortality on T. castaneum. Completely Randomized Design was used in this study with six treatments and four replicates. Concentrations used were 0%, 32,78%, 36,88%, 40,98%, 45,07% dan 49,17% which were obtained from preliminary test results and further more, the result was analyzed by probit analyzed method to determined concentrations would be used. LC50 value was 40,98% and ± 10%. The results was the best treatment on 45,78% with 96,2% and classified very strong repellent index. The lowest repellent index was 32,78% with 89,2% and classified strong repellent index. The highest Mortality of T.castaneumon 40,07% with 17,5% mortality dan the lowest mortality on 0% and 36,88% with no T. castaneum died. LC50 was 87,018%. We could conclude that E. suaveolenspossessed very strong repellent index on T. castaneum, but not effetive to kill T.castaneum.

Abstract

Produktivitas tanaman karet di Sumatera Selatan berkisar 1,17 ton/ha/tahun. produksi tersebut berbanding jauh dibanding negara Thailand yang mencapai 1,9 ton/ha/tahun. faktor yang mebuat produksi tersebut rendah yaitu genetik, kesuburan tanah, pemupukan, hama dan penyakit tanaman. Penyakit kering alur sadap merupakan penyakit tanaman karet yang sering mengganggu produktivitas tanaman karet. Penelitian ini dilaksanakan pada tanaman karet masyarakat berumur ± 15 tahun. Survei ini dilakukan di Desa Pulau Harapan Kecamatan Sembawa Kabupaten Banyuasin Sumatera Selatan pada bulan November 2022-Januari 2023. Metode Penelitian yang digunakan adalah purposive sampling. Jarak tanamantanaman karet yang disurvey adalah 5 x 4 (m). Survei dilakukan dengan intensitas sampling sebesar 5% dari total luas tanaman karet ± 14 ha yang berarti total populasi ± 7500 batang tanaman karet dan sampel yang diambil 350 batang tanaman karetHasil Penelitian: Hasil survey penyakit kering alur sadap (Tapping driness panel) pada tanaman karet yang berumur ± 15 tahun (tahun tanam 2007), menunjukan persentase serangan penyakit KAS sebesar 32,52%. Sedangkan produksi lateks pada tanaman karet pada umur 15 tahun dengan klon PB 260 dan BPM 24 menunjukan angka berkisar di 1.044 ton/ha/tahun

Abstract

Watermelon (Citrullus lanatus) is a high-value crop that has been commercially cultivated both in the world and in Indonesia. Many factors affect the productivity of watermelon plants such as land use frequency and plant disease attack. The purpose of this study was to determine the severity of disease in 2 fields with different frequency of planting and the productivity in each of these fields. This research was conducted in June-August 2023 in Tanjung Laut Village, Suak Tapeh District, Banyuasin Regency. The method used in this research is survey method with sampling technique using Simple Random Sampling by taking 216 samples on each land. There were 2 fields used, namely field 1 which was the first time watermelon plants were planted and field 2 which had been planted with watermelon for 3 times (this research was the third time planting). The planting distance used was 0.6 x 4.5 (m). The results of this study are diseases that often attack watermelon plants in this study are anthracnose disease caused by Colletotrichum orbiculare, Cercospora disease caused by Cercospora citrullina, fusarium wilt disease caused by Fusarium sp. and yellow creeping disease. The percentage of anthracnose disease attack in this study was 98.99% in field 1 and in field 2 was 99.06%, which was not significantly different in the T test (P-value 0.93), while the severity of anthracnose disease in field 1 was 46.48% and in field 2 38.99 (P-value 0.0001). Fusarium wilt was the most alarming disease in field 1 at 31.48% and in field 2 at 13.43%. There was an association between the frequency of watermelon planting and the incidence of fusarium wilt disease (P-value 0.00001). Productivity of watermelon plants in field 1 averaged 4.04kg/plant or 14.5 tons/ha while field 2 had a productivity of 5.02/plant or 17.9 tons/ha. The T-test results showed a significant difference between land 1 and land 1 (P-value 0.00003).

Abstract

White root disease is a major disease threatening the productivity of rubber plants. The community’s knowledge about White root disease is still limited, especially in recognizing early symptoms and its impact on rubber plants. Therefore, this community service activity aims to socialize knowledge about White root disease to the rubber plantation community in Banyuasin III, South Sumatra. This activity involves a series of counseling and interactive discussions about White root disease, including the introduction of symptoms, impacts on plants and the environment, and the importance of early detection. In addition, this activity also involves field demonstrations on how to identify White root disease symptoms in rubber plants. The results of this activity show an increase in community knowledge and awareness about White root disease. The community has become more capable of recognizing the early symptoms of White root disease and understanding the importance of early detection to prevent further spread. This activity contributes positively to the efforts of sustainable rubber plant management in Banyuasin III, South Sumatra.
