Abstract

Hydroponic farming is a promising alternative to increase agricultural productivity and sustainability in Indonesia. In Pinrang district, the Lasinrang hydroponic community has successfully implemented this method, with farmer-to-farmer collaboration, knowledge sharing, and involvement in community activities forming a solid network of mutual support. Despite this success, lettuce farmers still face problems such as lack of effective cultivation knowledge, limited access to quality seeds and fertilizers, and constraints in obtaining profitable markets. Therefore, this study recommends overcoming these problems by strengthening social capital to increase the productivity of lettuce farmers in the Lasinrang Hydroponic community. This study aims to determine the effect of social capital both partially and simultaneously on the productivity of lettuce farmers in Lasinrang hydroponic community, Pinrang Regency. This research uses a quantitative descriptive approach. Data collection techniques using questionnaires, interviews, observation and documentation, while data analysis techniques using multiple linear analysis. The results showed that: (1) the trust variable has no positive effect on the productivity of lettuce farmers (2) the social network variable has no positive effect on the productivity of lettuce farmers (3) the social norm variable has no positive effect on the productivity of lettuce farmers (4) the trust variable, social network, social norms have no positive effect together on the productivity of lettuce farmers.

Abstract

The Way Bulok Watershed (DAS) is a tributary of the Way Sekampung Watershed which is administratively located in Pringsewu Regency, Lampung Province. The use of land cover due to increasing human numbers and activities has a significant impact on surface flow (runoff) of the Way Bulok Sub-watershed. This research aims to analyze changes in land cover and to determine the effect of changes in land cover on surface flow in the Way Bulok Sub-watershed area. The results of research conducted show that total rainfall has increased, in 2011 rainfall was 1342 mm/year and in 2017 it increased to 1570 mm/year. This is in line with the increase in river discharge, where the annual average river discharge in 2011 was 21.69 m3/s, increasing to 35.40 m3/s in 2017. Likewise, the surface flow coefficient value has increased from 0 .19 to .27 . The land cover in the Way Bulok Sub-watershed area is still dominated by agricultural areas which have an area of more than 50% each year, compared to the forest area which is only 2,123% of the total area of the Way Bulok Sub-watershed in 2017.

Abstract

This study aims to evaluate the impact of training and extension services on improving the quality of human resources in the agribusiness sector in Sumenep Regency. Using both quantitative and qualitative approaches, we conducted surveys with farmers who participated in the training and extension programs and performed statistical data analysis to assess their influence on agricultural knowledge, skills, and practices. The survey results indicate that most respondents reported increased knowledge about cultivation techniques, fertilizer use, and post-harvest management after attending the training. Additionally, there was a significant increase in agricultural productivity and the adoption of new technologies among the farmers who participated in the program. Statistical data analysis shows a significant relationship between participation in training and increased agricultural productivity (p < 0.05). However, challenges such as limited access to information and resources still need to be addressed in the program's implementation. These findings suggest that training and extension programs are effective in enhancing the quality of human resources in the agribusiness sector, but improvements in accessibility and program continuity are necessary to achieve more optimal results.

Abstract

The use of a mixture of rhizome extracts of red ginger, turmeric, and kencur to control armyworms (Spodoptera litura F.) is an important prospect in increasing the yield of sweet potato crops, because plant-based pesticides can be used in single or mixed forms. The study aimed to determine the influence of various mixed effects of different concentrations of extracts of several rhizomes on the mortality of Grayak caterpillar pest (Spodoptera litura F.) on sweet potato plants (Ipomoea batatas L.). As well as determining the concentration of rhizome extract mixture that is more effective in controlling Grayak caterpillar pests (Spodoptera sp.) on sweet potato plants (Ipomoea batatas L.). This study used a method with a Group Random Design (RAK) consisting of 5 treatments and 5 replicates. The treatment is: 1. Control (sterile water application), 2. A mixture of red ginger, turmeric, and kencur rhizome extracts 40%, 50%, 60%, 70%, 80%, 90% through food (Stomach poison). The experiment was arranged in a complete randomized design of four replicates each using instar 2 larvae of Spodoptera sp. as many as 280 heads. Research Results The observation results showed that there was an influence of each concentration tested on the pest Spodoptera sp. through food (Stomach poison) against the larvae of the second instar where the level of attack caused in the instar is very high, so the concentration used is 40%-90%. All concentrations showed a real effect on the larvae of the two instars, at a concentration of 40% a mortality rate of 11.50%, and the highest concentration was 90% with a mortality rate of 80%..

Abstract

This study aims to determine the effect of pruning on the growth and yield of cucumber variety Mercy. This research was organized using a Randomized Group Design (RAK) with treatments, namely: No pruning (P0), pruning shoots on the main stem (P1), pruning shoots of all lateral branches after the third internode (P2) and pruning 2 lateral branches that appear first after the 3rd internode (P3) with 5 replications. The variables observed in this study consisted of; plant length, number of leaves, total number of fruits, number of harvestable fruits, harvestable fruit length, harvestable fruit diameter, and harvestable fruit weight. Data were analyzed using the F test and if there were significant differences followed by the 5% BNT test. The results showed that the treatment without pruning (P0) was able to produce a better number of fruits than the pruning treatment, but the number of fruits produced was of poor quality. The best plant results were found in the shoot pruning treatment on the main stem (P1) because it was able to increase the number of leaves 24.19% compared to no pruning treatment (P0).

Abstract

Cucumber (Cucumis sativus L.) is one of the vegetable plants that has many benefits, namely besides being able to be used as vegetables, fresh vegetables, salads or pickles, cucumbers are also beneficial for health because the nutritional value of cucumbers is quite good as a source of minerals and vitamins. Efforts to increase cucumber plant production can be influenced by many factors, one of which is fertilization. Fertilization is a determining factor in efforts to increase the availability of nutrients for plants, thus the expected impact of fertilization is not only to increase the yield per unit area but also to be efficient in the use of fertilizers. The method in this research is Non Factorial Randomized Group Design with four treatments and six replications, namely A0 (Control), A1 (Cow dung manure dose of 3 kg / polybag), A2 (Cow dung manure dose of 5 kg / polybag) and A3 (Cow dung manure dose of 7 kg / polybag). The results showed that the treatment of cow dung manure gave a significant effect on the parameters of plant height and fruit weight. The best treatment is found in A3, which is the application of cow dung manure at 7 kg/polybag.

Abstract

The need for peanuts from year to year continues to increase in line with the increasing population, community nutrition needs, food diversification, and the increasing capacity of the feed and food industry in Indonesia. N, P, and K are important factors and must be available to plants because they function as metabolic and biochemical processes of plant cells. Nitrogen is used as a builder of nucleic acids, proteins, bioenzymes, and chlorophyll. The purpose of this study was to determine the effect of NPK fertilizer on the growth and production of peanut plants. This research was conducted from January 2023 to April 2023 at the Faculty of Agriculture, Graha Nusantara University Padangsidimpuan. The method in this research is Non Factorial Randomized Group Design (RAK) with 4 types of calcium fertilizer treatments: 0 g/polybag (C0), 3 g/polybag (C1), 5 g/polybag (C2) and 7 g/polybag (C3). The results showed that NPK fertilizer affected the number of pods, pod weight and seed weight. The calcium fertilizer treatment that gives the best results on soybean crop production is in the C2 treatment, namely a dose of 5 3 g / polybag.
