Abstract

The management of organic agricultural and livestock waste remains a challenge in society, primarily due to a lack of understanding regarding its potential for valuable and sustainable utilization. Organic waste is often perceived as mere refuse with no functional value, resulting in suboptimal management. This study aims to evaluate the level of public knowledge concerning the processing of organic agricultural and livestock waste, as well as the changes in knowledge following educational intervention. The research method employed was an online survey conducted via the social media platform Instagram, involving 2,048 respondents from the general public. The research instrument consisted of pre-test and post-test questionnaires covering five key indicators related to the utilization of organic agricultural and livestock waste. The results showed that the average knowledge level of respondents in the pre-test was 67.6%, which increased to 90.2% in the post-test, representing an improvement of 22.6%. The highest increase occurred in the indicator for utilizing animal waste as biogas and organic fertilizer, which reached 100%. These findings indicate that education delivered contextually and according to community needs can significantly enhance public understanding. This increase in knowledge is expected to serve as a foundation for fostering awareness and encouraging the implementation of independent, sustainable, and economically valuable waste management.

Abstract

The purpose of this study was to evaluate the effects of NPK fertilizer application and planting systems on the growth of rice (Oryza sativa L.). A factorial randomized block design (RBD) was employed with two factors: planting system (three levels) and NPK fertilizer dose (four levels). This resulted in 12 treatment combinations, each replicated three times, for a total of 36 experimental units. Data were analyzed using analysis of variance (ANOVA) appropriate for RBD, with Duncan's multiple range test (DMRT) applied to observational variables at α=0.05α=0.05 or α=0.01α=0.01. Analysis of variance revealed significant interactions between NPK fertilizer dose and planting system for plant height at 30 days after planting (DAP), plant height at 40 DAP, number of tillers at 40 DAP, wet plant weight, and wet root weight. The Jajar Legowo 2:1 planting system produced highly significant improvements in wet plant weight and wet root weight compared to other systems. Among NPK doses, the P3 treatment yielded the best overall effects on rice growth. The combination of Jajar Legowo 2:1 (S2) and P3 dose exhibited the superior performance across parameters.

Abstract

Oil palm (Elaeis guineensis Jacq.) is one of the world's important commodities as a producer of vegetable oil needed by various industries. Leaf area index is one of the indicators of plant growth seen from the size of the leaf surface area that carries out the photosynthesis process. This study aims to determine the interaction of NPK Phonska fertilizer dose treatment and its application method on the Leaf Area Index of oil palm seedlings at the pre-nursery stage. The study was designed using factorial RAK consisting of 2 factors, namely the dose of NPK Phonska fertilizer (K) and its application method (A), and 3 replications. The K factor consists of 5 levels, namely K0 = 0 g/seedling; K1 = 0.5 g/seedling, K2 = 1 g/seedling, K3 = 1.5 g/seedling, and K4 = 2 g/seedling. Factor A consists of 3 levels, namely A1 = watering, A2 = spreading, and A3 = bag. The observation results were analyzed using analysis of variance and further DMRT test at 5% level if significantly different. The results of the study showed that the dose of NPK Phonska fertilizer 1 g/seedling (K2) gave the highest results on the Leaf Area Index, which was 2.90. The interaction treatment of NPK Phonska fertilizer dose 1 g/seedling and the pocket application method (K2A3) gave the highest results on the parameters of seedling height (12.99 cm) and tuber diameter (1.31 cm). The Leaf Area Index weakened positively on the growth of oil palm seedlings as seen from the height of the seedlings, tuber diameter, and leaf sheath length.
