Abstract

The people of Simeulue Island, Aceh, have a long-standing tradition of coconut gardening. Before the 2004 earthquake and tsunami, coconut production in this area was quite high. However, in recent years, the decline in coconut production has threatened the supply of raw materials for the local processing industry. As a result, hundreds of tons of raw materials must be imported from Nias Island to meet the needs of the industry. One of the main causes of this decline is suboptimal harvesting practices. This study revealed that most coconut varieties cultivated in Simeulue are Kelapa Dalam, which has a productive age of 10 and 30 years. Based on visitation patterns, there are two types of coconut gardens: those that are regularly visited and those that are rarely visited. The rarely visited gardens are only visited during harvest time, about once every three months. The vegetation in these gardens tends to be denser, but their productivity is difficult to control. Most of the productive coconuts currently come from low-quality seeds, namely small coconuts that are not harvested because they are considered uneconomical. These seeds are often less than 1 kg; some are as big as 250 ml mineral water bottles. Efforts are needed to ensure the sustainability of the coconut industry in Simeulue; efforts are needed to provide superior seeds that can improve the quality and quantity of future harvests.

Abstract

The purpose of this study was to determine the production input and input price efficiency in rice farming in Padangguni District, Konawe Regency. The determination of the location of this study was carried out considering that in this place almost all the people are engaged in rice farming. The sample in this study was taken using a simple random sampling method with a sample size of 100 respondents. To determine the effect of the use of production inputs in rice farming in Padangguni District, Konawe Regency, regression analysis and price efficiency were used. The production factors used in the form of land, labor, seeds, fertilizers and pesticides have a significant effect on the production of rice farming in Langgea Village, Padangguni District, Konawe Regency. This shows that these production factors complement each other and are very much needed to increase the productivity of rice farming. The combination of the use of production factors for rice farming in Langgea Village, Padangguni District, Konawe Regency is not yet efficient. This is indicated by the efficiency value of each production factor which is not equal to one (NPMxi / Pxi ≠ 1), namely; land rental efficiency value (0.94), labor (0.30), seeds (1.77) fertilizer (0.77) and pesticides (0.69). This means that the combination of the use of production factors for rice farming is still inefficient.

Abstract

Potato (Solanum tuberosum L.) is often considered a drought-sensitive crop, and its sustained production is increasingly threatened by frequent drought events. Drought presents one of the most significant challenges to potato production worldwide. Plants experience water stress when the water they receive is insufficient to meet their actual needs. The effects of drought stress range from disruptions at the molecular and biochemical levels within cells to physiological and morphological impairments at the leaf and whole-plant levels. Potato plants are particularly vulnerable to drought due to their shallow root systems. As a result, climate change is expected to have a considerable impact on global potato production, as limited water availability can significantly reduce tuber yield. Potato plants respond to drought stress through various physiological, biochemical, and molecular strategies. This review compiles research findings to better understand the impact of water stress on tuber formation, the mechanisms through which drought stress affects potato plants, the plant's resistance responses, and strategies to mitigate the effects of drought stress in potatoes.

Abstract

Soil salinity has emerged as a major constraint to global food production, with its severity continuously escalating due to anthropogenic activities such as excessive irrigation, land degradation, and climate change. Wheat (Triticum aestivum L.), a staple crop and primary source of carbohydrates and energy for much of the global population, is particularly sensitive to salinity stress. High salt concentrations adversely affect the plant’s physiological and biochemical processes, including inhibited seed germination, stunted vegetative growth, disrupted reproductive development, reduced enzymatic activity, and impaired photosynthesis. Salinity stress also causes hormonal imbalances, induces oxidative stress through the accumulation of reactive oxygen species (ROS), and ultimately leads to significant yield losses. A comprehensive understanding of wheat’s responses to salinity stress is essential for developing effective mitigation strategies. Efforts to enhance salinity tolerance have included the selection of tolerant genotypes, conventional breeding programs, and molecular approaches such as genetic engineering. While promising, these methods are often time-consuming, costly, and labor-intensive. As a complementary solution, agronomic management practices have gained attention for their practical application in improving wheat performance under saline conditions. Techniques such as the use of arbuscular mycorrhizal fungi, plant growth-promoting rhizobacteria (PGPR), exogenous phytohormone application, seed priming, and proper nutrient management have shown effectiveness in enhancing plant resilience and productivity in saline soils. This paper reviews the physiological impacts of salinity on wheat, explores potential adaptive mechanisms, and discusses practical management strategies aimed at improving wheat performance under salt stress conditions.

Abstract

One of the invasive pests that target corn plants is the armyworm Spodoptera frugiperda. This pest can cause damage to every area of the corn plant. Botanical insecticides can be used to control S. frugiperda since it is better for the environment. Rotenone found in the T. vogelii is toxic to insects. The purpose of this study was to assess the effect of the botanical pesticide T. vogelii seed extract mortality of S. frugiperda. T. vogelii seed extract was produced by using a Soxhlet extractor. The tests were conducted using contact poison and stomach poison methods, with the concentrations of the extract solution tested being 0.0625, 0.125, 0.25, and 0.5%. T. vogelii seed extract demonstrated the highest mortality value against S. frugiperda, which is 100% at a concentration of 0.5% in both the contact poison and stomach poison methods. T. vogelii seed extract shows strong toxicity with LC50 = 0.221% and the shortest mortality at 0.5% concentration with LT50 = 2.214 days against S. frugiperda, with an LC50 of 0.316% and the fastest mortality at 0.5% concentration, with an LT50 of 2.457 days. Further research is needed to determine the effect of T. vogelii seed extracts both in the screen house and in the field

Abstract

The involvement of women as rice farm labourers in Pondok Kubang District causes their working time to be divided into productive, domestic, social, and leisure activities, which are measured in hours per week. This study aims to analyse the working time of female rice farm labourers and the factors that influence it, including age, education, number of dependents, previous season's income, head of household income, and work experience of farm labourers. The study was conducted in December 2024 using a census technique on 102 respondents who worked on other people's rice fields. The analysis methods used include analysis of working time and multiple linear regression. The study's results showed that the average working time of female farm labourers in productive activities was 46.03 hours per week, for domestic activities 39.97 hours per week, for social activities 4.94 hours per week, and for leisure time 9.06 hours per week. Simultaneously, all independent variables have a significant effect. Partially, the variables of age, previous season's income, head of household income, and work experience have a significant effect, while education and number of dependents have no effect.

Abstract

 In order to reduce imports, diversify non-gluten products especially for celiac and autism sufferers, it is necessary to replace wheat flour, especially in making steamed brownies, including with cowpea flour. However, cowpea does not contain gluten which makes the cake elastic and soft, so it is necessary to add emulsifiers to maintain its elasticity. This study aims to determine the effect of different types and concentrations of emulsifiers on the physicochemical and organoleptic quality of brownies based on white cowpea flour and determine which composition is the best. The method used in this study is a completely randomized design (CRD) with one factor, namely the formulation of emulsifier types (J1 = SP and J2 = ovalet) and concentrations (K1 = 1% and K2 = 2%), each of which was repeated three times. The research variables observed were the analysis of the physical quality of brownies on their rising power, chemical analysis including water content, crude fiber and protein content, while the organoleptic quality analysis included tenderness, aroma, taste and color. The results showed that different types and concentrations of emulsifiers had a significant effect on water content, swelling power and tenderness. While the parameters of protein content, crude fiber, taste, color and aroma did not have a significant difference. The results showed that the best formulation was in the J2K2 treatment (Ovalet emulsifier with a concentration of 2%) with an average swelling power value of 39.42%, water content of 7.47%, crude fiber content of 3.97%, protein content of 1.21%, with an average value of organoleptic parameters of taste of 5.6 (like), aroma of 6.1 (like), tenderness of 5.53 (rather like) and color of 6.6 (very like).
