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).

Soil pH value either with KCl solution or with H2O are two important indicators needed to describe soil acidity. This study aims to determine the distribution of soil pH values in smallholder rubber plantations with different land topography classes in Pelepat Ilir Subdistrict, Bungo Regency, Jambi Province. The study used a survey method with a toposequence concept approach at a semi-detailed level, where observation points were made based on the upper tread polypedon, middle tread polypedon, and lower tread polypedon at each level of percent slope 15-24%, 8-15%, and 3-8%, and flat tread polypedon at a percent slope of 0-3%. Ten composite soils were taken from a mixture of 3 individual soil samples at each polypedon using a soil drill at a depth of 0-30 cm from the soil surface. Soil pH value analysis was conducted in the laboratory on each composite. The results showed that the pH value of the soil with 1:2 H2O solution was very acidic, and acidic for 1:2.5 KCl solution. The distribution of soil pH values showed that the lower slope had a higher pH value than the middle slope, and the upper slope had the lowest pH. Soil pH values decreased as the slope increased, and soils with flat topography were considered more fertile than those with high slopes. This result can be a recommendation in determining liming and fertilization doses, where higher doses are required for high slope soils than flat soils for optimum agricultural yields.

Penilaian status kesuburan tanah penting dijadikan acuan dalam optimalisasi pengelolaan, peningkatan efisiensi dan produktivitas lahan pertanian. Penelitian ini bertujuan untuk mengetahui status kesuburan kimia tanah pada perkebunan karet rakyat melalui survei dengan pendekatan konsep posisi polypedon tanah dan kelas lereng lahan di Provinsi Jambi. Sampel tanah komposit diambil dari polypedon tanah atas, tengah, dan bawah pada tingkat persen lereng lahan 15-24%, 8-15%, 3-8%, dan 0-3%. Paramater kesuburan kimia tanah yang dianalisis adalah Kapasitas Tukar Kation (KTK), Kejenuhan Basa (KB), P2O5, K2O, C-Organik, N-Total dan pH tanah. Penentuan status kesuburan berdasarkan kriteria yang dikeluarkan Pusat Penelitian Tanah Bogor tahun 1983. Hasil penelitian menunjukkan bahwa status kesuburan kimia tanah tergolong rendah pada semua tingkat lereng lahan dan pada semua polypedon. Optimalisasi produktivitas budi daya tanaman karet di lokasi penelitian direkomendasikan agar melakukan pengapuran untuk peningkatan pH tanah, pemberian bahan organik dan pemupukan, terutama pupuk dengan unsur hara nitrogen, dan kalium.

Water hyacinth (Eichhornia crassipes) is a weed that lives in water and has a high growth rate. It has the ability to increase evapotranspiration (evaporation and loss of water through plant leaves), reduce the amount of light entering the water, resulting in a decrease in the level of oxygen solubility in water, disrupt water traffic, and increase habitat for disease vectors. aquatic environment. A solution is needed to overcome this problem, one of which is by composting. In order for composting to take place faster, Starbo AFE and Probio FM activators are used which will provide good quality. this study aims to determine the effect of various activators on the nutrient content of water hyacinth compost, and to determine the best combination of activators on the nutrient content of water hyacinth compost. This research method uses one replication with three treatments (K1 K2 and K3 using Starbo AFE and Probio FM, and K0 without Starbo AFE and Probio FM). This study was conducted in two stages, namely the composting stage. The composting process was carried out for 30 days. Checks are carried out every 5 days in the form of turning and physical observation. After the composting process is complete, nutrient measurements are carried out. Characterization is carried out to determine the levels of C-Organic, N, P, K, and Aroma. The results of this study showed that Starbo AFE and Probio FM are effective against C-Organic, N and K levels and aroma in accordance with SNI.
