COMPARISON OF INCOME AND STAPLE FOOD AVAILABILITY OF RAWA LEBAK RICE FARMING HOUSEHOLDS BASED ON LAND TYPOLOGY IN KALIDONI DISTRICT, PALEMBANG CITY
No full textLebak swamp land is a type of suboptimal land with high potential for the development of national rice production, although it is highly influenced by climatic conditions and the typology of water inundation. Variations in lebak swamp land typology lead to differences in productivity, as well as in household farmers' income levels and food availability. This study aims to analyze household income sources and staple food availability among rice farmers based on the typology of lebak swamp lands (shallow, middle, and deep) in Sei Selincah Subdistrict, Kalidoni District, Palembang City. A survey method was employed using proportional stratified random sampling, involving 60 respondents. Data were analyzed quantitatively to calculate income, expenditure, and food availability. The results showed that the highest income was earned by farmers in deep swamps (IDR 27,832,049/year), followed by middle swamps (IDR 26,221,862/year), and shallow swamps (IDR 24,609,383/year). Non-agricultural income significantly contributed to household finances, particularly in shallow and middle areas. Non-rice farming activities, such as galangal cultivation, were only practiced in shallow and middle swamps. Household expenditures were primarily allocated to non-food needs, especially education and savings. Meanwhile, household food availability remains low and varies across land typologies. The highest food availability is found in the middle swamp at 443 kg/year, followed by the deep swamp at 425 kg/year, and the shallow swamp at 405 kg/year. Most of the surplus is sold to meet other household needs. These findings highlight the importance of income diversification and improving food storage capacity to enhance the economic and food security of lebak swamp rice farmers.

FORMULATION, SENSORY EVALUATION, BIOACTIVE COMPOUNDS, ANTIOXIDANT ACTIVITY, AND ALPHA-GLUCOSIDASE INHIBITION OF FUNCTIONAL INFUSION BEVERAGE FROM MACE AND NUTMEG SEEDS (MYRISTICA ARGENTEA WARB.)
No full textFunctional tea bags containing mace and nutmeg (Myristica argentea Warb.) were developed to support blood glucose regulation amid the rising prevalence of degenerative diseases, including diabetes mellitus, in Indonesia. Both ingredients contain bioactive compounds such as flavonoids, myristicin, and phenolic acids that may contribute to glucose regulation. This study evaluated the effect of varying mace and nutmeg proportions on sensory acceptance, determined the optimal formulation, and assessed bioactive properties, antioxidant activity, and alpha glucosidase inhibitory potential. A one-factor Completely Randomized Design (CRD) was applied with four formulations: F1 (0.05 g : 0.25 g), F2 (0.10 g : 0.20 g), F3 (0.15 g : 0.15 g), and F4 (0.20 g : 0.10 g). Sensory evaluation used a seven-point hedonic scale for color, aroma, taste, and aftertaste, analyzed by chi-square and Duncan’s Multiple Range Test (DMRT) if a 5% significance level. The optimal formulation was determined using the De Garmo method. Results showed that varying proportions significantly affected all sensory parameters. F2 (0.10 g : 0.20 g) achieved the highest scores: color 5.98, aroma 6.51, taste 6.40, and aftertaste 6.00. Its bioactive profile included total phenolics of 20.91 mg GAE/g, total flavonoids of 0.3 mg QE/g, and antioxidant activity with an IC50 of 448.78 ppm (weak). F2 also showed increasing alpha-glucosidase inhibition with rising concentrations, reaching 31.56 % at 100,000 ppm. These findings indicate that F2 exhibits low alpha glucosidase inhibitory activity due to its limited phenolic and flavonoid content, highlighting the need for formulation and extraction optimization to enhance the bioactive compound levels and the functional potential of mace–nutmeg tea bags in a herbal jamu preparation
POTENTIAL AND CHALLENGES OF UTILIZING FAMILY YARDS TO SUPPORT EDUCATION-BASED FOOD SECURITY
No full textThe utilization of home gardens has significant potential to support household food security while serving as a medium for ecological and family-based education. This study aimed to describe the conditions of yard utilization, analyze family perceptions and attitudes, and identify the practices and challenges faced in their management. A descriptive quantitative–qualitative approach was employed involving 30 families in Mojogedang District, Karanganyar. Data were collected through observation, interviews, and a five-point Likert-scale questionnaire measuring yard size and function, cultivation skills, motivation level, family participation, and support for children’s involvement. The data were analyzed descriptively to explore the relationships between physical yard conditions, family perceptions, and management constraints. The results show that most families own yards measuring 50–100 m² (40%), exhibit high motivation for productive use (80% agree–strongly agree), and express full support for involving children in yard activities (100% agree–strongly agree). The main challenges include limited cultivation skills, lack of production inputs, and time constraints for management. This study recommends the development of the Rumah Pangan Berkemajuan (RPB) Model based on four pillars: technical strengthening, integration of family education, socio-economic networking, and religious–ecological values. These findings provide a conceptual foundation for yard management oriented toward sustainable food security and ecological family character education
ANALYSIS OF ARABICA COFFEE (Coffea arabica) GROWTH UNDER THE SUREN (Toona sureni) SHADE TREE IN GENTENG VILLAGE, SUKASARI DISTRICT, SUMEDANG REGENCY
No full textArabica coffee (Coffea arabica) is one of the leading plantation commodities whose growth is strongly influenced by environmental conditions, particularly the availability of shade from canopy trees. This study was conducted to analyze the influence of suren trees (Toona sureni) on the growth of Arabica coffee of the Ateng Super variety in Genteng Village, Sukasari District, Sumedang Regency. The research was carried out in April–May 2025 on a 0.7 ha community owned land with a sampling intensity of 15%. The observed parameters included total height, clear bole height, and diameter of suren shade trees, as well as the number and length of productive branches of coffee plants. Data were analyzed using classical assumption tests and multiple regression with t-tests through RStudio software.The results showed that the morphological characteristics of suren trees total height, clear bole height, and diameter did not directly influence the number or length of productive branches of Arabica coffee. Nevertheless, the presence of suren as a shade tree played an important role in creating a microclimate conducive to coffee growth. Microclimate observations indicated that suren shade could maintain ideal temperature and humidity ranges, namely 22–24°C and 72–83%, thereby helping stabilize the growing environment for coffee plants. With these capabilities, suren trees are considered suitable as shade species in Arabica coffee agroforestry systems. Their presence does not hinder coffee plant growth; instead, they contribute to establishing optimal environmental conditions for vegetative development and overall plant productivity.

UTILIZATION OF CASSAVA SKIN AS POC MATERIAL AND 50% NPK FOR GROWTH AND PRODUCTION OF LETTUCE (LACTUCA SATIVA L.) ON ULTISOL LAND
No full textUltisol land is one of the types of soil that is less fertile and has a high level of acidity, making it a challenge in the cultivation of horticultural plants such as lettuce (Lactuca sativa L.). The excessive use of chemical fertilizers not only has a negative impact on the environment but also degrades soil quality sustainably. Therefore, environmentally friendly innovations are needed, one of which is the utilization of household organic waste such as cassava peels as the base material for Liquid Organic Fertilizer (LOF). This study aims to determine the effect of the combination of Cassava Peel Liquid Organic Fertilizer (LOF) and 50% NPK fertilizer on the growth and production of lettuce plants in ultisol land. The research was conducted in February-March 2025 using a Randomized Block Design (RBD) with four treatments, namely without LOF (100% NPK), and cassava peel LOF with doses of 13.75 ml, 15 ml, and 16.25 ml, each combined with 50% NPK. The observed parameters include the number of leaves, leaf width, leaf length, root length, fresh weight, canopy weight, and root weight. The research results show that the application of cassava peel LOF has a significant effect on the number of leaves, leaf width, leaf length, root length, fresh weight, canopy weight, and root weight. The use of cassava peel LOF, especially at a dosage of 16.25ml, can enhance the growth and production of lettuce compared to the application of 100% NPK. This treatment can be an alternative to environmentally friendly fertilizers in marginal lands such as ultisol.

ANALYSIS OF PHYSICOCHEMICAL AND ORGANOLEPTIC CHARACTERISTICS OF YELLOW PUMPKIN PUDDING (CUCURBITA MOSCHATA)
No full textYellow pumpkin (Cucurbita moschata) is a nutrient-rich horticultural commodity with considerable potential for development into various food products, including pudding. However, scientific information regarding the effects of pumpkin incorporation on the physicochemical and sensory characteristics of pudding remains limited. This study aimed to evaluate the influence of different proportions of pumpkin (30%, 50%, and 70%) on the physicochemical properties, vitamin C content, and sensory acceptance of pumpkin pudding. A Completely Randomized Design (CRD) was employed with three replications for each treatment. The analyses included syneresis at two storage conditions (refrigerated and room temperatured), total dissolved solids (TDS), texture (hardness), color parameters (L*, a*, b*), vitamin C content determined by iodometric titration, and a hedonic test involving 30 untrained panelists. Data were analyzed using ANOVA followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that increasing the proportion of pumpkin had significant effects on TDS, texture, color attributes, vitamin C content, and most sensory parameters. Higher pumpkin concentrations decreased TDS and hardness values while increasing syneresis due to higher free-water content within the gel matrix. Lightness (L*) and vitamin C levels increased proportionally with the amount of pumpkin added. Sensory evaluation revealed that the 30% pumpkin formulation received the highest scores for color, aroma, texture, taste, and overall acceptance, whereas the 70% formulation received the lowest scores, particularly for color and chewiness. These findings indicate that the 30% pumpkin incorporation provides the most optimal balance of physical quality, nutritional enhancement, and consumer acceptability.

EFFECTIVENESS OF BIOCHAR RESIDUE COMPOSITION AND ORGANIC FERTILIZER ON CAULIFLOWER CROPS
No full textDegraded soil that loses many nutrients becomes unproductive and is therefore less suitable for agriculture. One of the efforts to improve degraded soil is by adding organic materials, such as biochar and cow manure. Biochar as a soil ameliorant has been proven to improve the physical, chemical and biological properties of the soil. When combined with manure, plants production will be much more optimal. This study aims to study the effects of biochar residue and cow manure in the second planting season on the growth and yield of cauliflower plants in paddy fields. The study was conducted in August - October 2023 in Lowokwaru District, Malang City. The study used a 1-factor Randomized Block Design (RBD) which was a mixture of biochar residue and cow manure consisting of 7 treatments, namely P0 (control), P1 (100% cow manure), P2 (100% biochar), P3 (80% biochar: 20% cow manure), P4 (60% biochar: 40% cow manure), P5 (40% biochar: 60% cow manure), P6 (20% biochar: 80% cow manure). Based on the results of the study, the treatment of biochar residue and cow manure had a positive effect on the growth and yield of cauliflower plants. The treatment of 60% biochar residue: 40% manure (P4) was the best treatment for harvest results, namely the best crop and leaf weight of 485.89 g, crop weight of 274.11 g and harvest yield of 7.57 tons/ha compared to the control of 5.54 tons/ha
