Abstract

Agricultural extension services (PPL) have the task of counseling farmers and farmer groups to improve their welfare. One of the farmer groups that became the counseling target was the women farmer groups (KWT). This study aimed to analyze the performance of agricultural extension services in the Women Farmer Group (KWT) in Bajo District, Luwu Regency, South Sulawesi, and the influence of personal characteristics, group environment, and social environment on the performance of extension workers. The research method used in this study was a quantitative approach with a descriptive and explanatory design. The research population was KWT members in the Bajo District using a saturated sample in which all populations become respondents. Data analysis used the Varian-Based Structural Equation Modeling (VB-SEM) analysis technique with Smart PLS 3.0 application. The results showed that the performance level of the extension worker was 72.02 on a scale of 10 to 100. Personal characteristics, group environment, and social environment significantly influenced the performance of the extension worker. In this case, to improve their performance, extension services need to encourage the involvement of farmer group members in all stages of extension activities. In addition, extension services need to improve the dynamics of farmer groups to be more developed and dynamic so that members can benefit from the group. Furthermore, extension services need to continue to establish harmonious social relations with the surrounding environment to create conditions conducive to farmer groups' activities and the implementation of extension activities.

Abstract

The porang plant is a tuber plant. Porang tubers currently have an economical selling value. Due to the economic value of porang, several regions in Indonesia now cultivate it. Therefore, land suitability analysis is needed to determine whether or not porang or other commodities can be planted in an area. This study aimed was determining the actual and potential land suitability classes on porang land and the constraints that may occur, also mapping the land suitability of porang in three villages of Kare District, Madiun Regency, Indonesia, i.e., Kuwiran, Randualas, and Kare, using a system geographic information (GIS). This study used survey and matching methods while making maps using ArcGIS 10.4 software. Primary and secondary data were obtained from laboratory analysis results, field observation, and related data from the Meteorology, Climatology, and Geophysics Agency (BMKG). The results showed that Kare Village had good potential for porang cultivation based on the results of spatial data processing. The actual land condition for porang cultivation in Kuwiran Village was 10 ha, Randualas Village was 28 ha, and Kare Village was 18.55 ha. The limiting factors at the study site were nutrient retention and availability. Some efforts can be made to improve the land by applying organic matter, compost, and liming.

Abstract

One of the keys to successful quail rearing is choosing suitable nutritional feed. Unfortunately, feed nutrients not adequately absorbed by the digestive tract of quails, in addition to impacting productivity, will also be wasted and decompose to form ammonia, which becomes a supporting factor for disease. This study aims to determine how adding turmeric powder and nitrifying probiotics affect the productivity and amount of ammonia from quail excreta. The research design used was a completely randomized design (CRD) with 6 (six) treatments, i.e., control (without the addition of turmeric powder and nitrifying probiotics), the addition of nitrifying probiotics 4.5 g/kg of feed, the addition of nitrifying probiotics 6 g/kg of feed, the addition of turmeric powder 3 g/kg of feed, the addition of 3 g turmeric powder + nitrifying probiotics 4.5 g/kg of feed, and the addition of 3 g turmeric powder + nitrifying probiotics 6 g/kg of feed. Data were analyzed statistically using ANOVA and followed by the DMRT. The results showed that adding turmeric powder and nitrifying probiotics had no effect on feed consumption, feed conversion ratio (FCR), protein efficiency ratio (PER), and ammonia level in quail excreta but had a significant impact on quail day production (QDP). This study concluded that adding turmeric powder and nitrifying probiotics can improve the value of QDP, PER, and reduce ammonia levels in quail excreta but had not been able to enhance the value of feed consumption and feed conversion ratio.

Abstract

Solar radiation is essential for the evolution of life on earth. Solar radiation, including ultraviolet radiation (UV), reaches the earth's surface. The sun emits three types of UV radiation: UVA, UVB, and UVC, which have beneficial and harmful effects on the human body. The most important benefit is the synthesis of vitamin D in the skin. However, UVB radiation also causes direct photochemical damage to DNA. This study aimed to investigate the ability of the compound ethyl-p-methoxycinnamate (EPMS) that is available in kencur as a sunscreen agent through computational chemistry studies using the Hartree-Fock (HF) method and time-dependent density functional theory (TD-DFT) and perform synthesis of lotion from kencur extract. The investigation began with creating a molecular model of a sunscreen agent optimized for geometry using the HF method and continued with spectrum analysis using TD-DFT. The study's results showed that the analysis of the EPMS spectrum could be used as a natural UVB shield. In addition, the synthesis of lotion from kencur rhizome made using oil and water phases showed organoleptic, pH, homogeneity, and spreadability test results fitted according to the Indonesian National Standard (SNI) 16-4399-1996. It indicated that kencur lotion could potentially be used as a sunscreen agent.

Abstract

Beetles, the order Coleoptera, are post-harvest rice product pests that cause severe quantitative and qualitative damage. Therefore, the diversity of pest beetles found in rice warehouses is essential because it leads to pest management by detecting and identifying beetles that can be the basis for making decisions in Integrated Pest Management (IPM). The study was conducted at two rice warehouses, Cakranegara I and Ubung, Indonesia, with rice sampling at five points diagonally on each side. Rice was taken using the Nobbe Trier tool inserted into the sack, and 100 g was taken as a rice sample. Rice sampling was conducted from June to July 2019, with five points diagonally on each side of a pile of rice. The results obtained four pest beetle species: Sitophilus oryzae, Cryptolestes ferrugineus, Oryzaephilus surinamensis, and Tribolium castaneum. Based on the Shannon Wiener index (H’) in Cakranegara I warehouse, the pest beetle found was only C. ferrugineus with a low diversity level of 1.60. Meanwhile, four pest beetle species were found in the Ubung warehouse S. oryzae, C. ferrugineus, O. surinamensis, and T. castaneum, with a moderate diversity level of 2.74. The differences in the diversity of pest beetles in storage were influenced by the rice warehouse's temperature and relative humidity (RH).

Abstract

The soybean needs of the people in Ternate are fulfilled by imported soybeans that enter through Surabaya. The process of transporting imported soybean seeds from Surabaya to the port of Ternate and storage in warehouses may lead to contamination with Peronospora manshurica fungus, which poses a risk of spreading to soybean crops in Ternate. This study aims to detect the presence of P. manshurica fungus, viability, and growth of P. manshurica oospores in the imported soybean storage warehouses in Ternate. The study was conducted using a combination of qualitative and quantitative methods. The qualitative method was carried out through an exploratory approach, while the quantitative method used a randomized block design (RBD) consisting of four treatments, i.e., G.Tbsi, G.Jbla, G.Tfra, and G.Tfrb, with five replications. The observation variables included disease occurance, presence, and characteristics of oospores, as well as oospore growth and viability percentage. The results showed that the average disease occurance in the soybean storage warehouses was highest in the sample of soybeans from the Tfrb warehouse at 1.88%, followed by the Jbla, Tfra, and Tbsi warehouses at 1.44%, 1.41%, and 1.24%, respectively. The study also found P. manshurica fungus in all four soybean storage warehouses in Ternate, with a viability percentage of G.Tbsi, G.Jbla, G.Tfra, and G.Tfrb were 25.8%, 28.8%, 27.4%, 26.5% respectively. These findings indicate the potential for disease spread to soybean crops in Ternate, thus necessitating appropriate preventive measures to address this problem.

Abstract

Sourdough bread is known to have health benefits due to its fermentation process using lactic acid and wild yeast. It can improve the taste, texture, shelf life, and nutritional content of bread as a functional food. In this study, sourdough was made from fermented papaya with varying fermentation times of 4, 5, and 6 days. The substrate was fed five times to strengthen the sourdough, resulting in a robust enough mixture to develop the dough. The resulting sourdough was used to create sourdough bread with a 30% sourdough concentration. The fermentation time impacted the quality of the sourdough, with results showing that sourdough became increasingly active as fermentation time progressed. The best sourdough was obtained from a six-day fermentation period, with a pH of 3.60 and a total plate count of 1.70 × 104 CFU/ml. The best donuts were produced using the sourdough that had been fermented for six days, with an almost perfect score of 3.9 out of 4 for all aspects, including color, aroma, taste, and texture. Using this sourdough resulted in a significantly longer shelf life; no mold appeared until the eighth day of storage at room temperature. The moisture content of the donuts was measured at 4.57%. This study demonstrates the potential benefits of using sourdough made from fermented papaya to improve the quality and shelf life of sourdough bread while also providing potential health benefits.

Abstract

Mineral or inorganic fertilizers are increasingly being used to increase tomato productivity. However, excessive use of inorganic fertilizers may negatively impact soil fertility and microbial activity. To maintain food safety and agricultural sustainability, the use of inorganic fertilizers must be balanced with organic fertilizers. Additionally, sub-optimal land, such as dryland, can be used to optimize tomato productivity, particularly in the North Lombok Regency, Indonesia. This study aimed to investigate the effect and interaction of a combination of liquid organic fertilizer (LOF), plant growth regulator (PGR), and NPK fertilizers as inorganic fertilizers on the growth and yield of tomatoes in dryland. The experimental design was a completely randomized block design, with two factors: the concentrations of commercial inorganic fertilizer (0, 1,300, and 2,600 ppm) and the type of commercial LOF (Bio-Extrim and Organox) + commercial PGR (Hormax). The results showed that the interaction was not significantly different between inorganic fertilizer and LOF + PGR, except for mean fruit weight in the first week of harvest. However, there were differences in responses at the level of each factor. The application of inorganic fertilizer at 2,600 ppm increased tomato productivity by 13.81%. LOF was only significantly different in fruit weight/plant in the first week of harvest and was not significant after that.

Abstract

Sugar production in Indonesia has decreased by 2.12 million tons (4.65%) in 2020 due to the limited supply of superior varieties. The purpose of this study was to understand the potential of the expected superior clones before being released as new superior varieties. This study was conducted in Sidoarjo, Indonesia which has alluvial soil types. This study used a randomized block design (RBD) with one treatment factor (clone) consisting of clones SB01, SB03, SB04, SB11, SB12, SB19, SB20, and varieties PS 881, and MOJO. Data analysis used 5% ANOVA, 5% least significance difference test, correlation test, genetic diversity test, and heritability test. The results of the analysis showed significant differences with all treatments at 48, 50, and 52 weeks after planting (WAP) in the variable brix while the sugarcane stems weight, rock crystal, and yield were significantly different only at 52 WAP which were tested in multilocation in paddy fields and alluvial soil types. Clone SB01 showed the highest brix value of 26.88%, the highest stem weight of 149.20 tons/ha, the highest yield of 10.63%, rock crystal 15.87 tons/ha, the value of genetic diversity in the moderate category was seen in crystal characters (12.55 %), phenotypic diversity in the moderate category was seen in crystal characters (14.364%) and the heritability value was in the fairly high category in brix characters (0.96%). This study shows that the characters inherited from their parents are relatively stable.
