Abstract

ND virus causes mortality in poultry. Passively acquired maternal antibodies inhibit immunoglobulin formation. Repeatability is a genetic parameter that determines the inheritance of traits from elders to chicks. IPB-D2 chickens were selected for disease resistance, and IPB-D3 chickens were selected for weight gain. This study aimed to evaluate the productivity of IPB-D2 and IPB-D3 chickens and assess the inheritance of Newcastle Disease (ND) antibody traits in 36 IPB-D3 and 21 IPB-D2 chickens. The T-test was used to compare the group means of the two chicken breeds. Antibody titer measurements were based on the Geometric Mean Titer (GMT). Estimation of ND titer repeatability using within-class correlation. Fertility and hatchability differed significantly (p < 0.05). ND titer of IPB-D2 chicken and IPB-D3 chicken DOC LOG 2 GMT 1.61 ± 1.10 and 1.34 ± 0.95. The antibody titer of IPB-D2 and IPB-D3 chickens at 14 days of age was 1.02 ± 1.20 and 1.37 ± 0.95. The ND titer value in the egg yolk of IPB-D2 chicken was 4.02 ± 1.94, and in IPB-D3 chicken was 3.64 ± 2.54. The results showed the repeatability value of l antibodies in IPB D-2 chickens and IPB D-3 chickens in DOC 0.49±0.30, 0.42±0.33 and 0.39±0.28; 0.25±0.15, respectively. Fertility and hatchability of IPB-D3 chickens were better than those of IPB-D2 chickens. The yolk ND titer of IPB-D2 chickens was higher than IPB- D3 chicken. The ND titer reciprocity of IPB-D2 chickens was higher than that of the IPB-D3 chickens. Keywords: IPB-D2 Chicken, IPB-D3 Chicken, Newcastle Disease, productivity, repeatability

Abstract

In vitro embryo cultivation is the principal method for reproducing the kopyor coconut, an indigenous Indonesian species. Acclimatization is a critical step in this approach. The purpose of this study was to improve the survival and development rate of kopyor coconut seedlings grown in vitro during the acclimatization phase by using biological, organic, and mixed organic-biological biostimulants. This study employed a completely randomized block design that comprised the inclusion of biological, organic, and mixed biological-organic biostimulants, with no biostimulant as a control. The biological stimulant employed in this study was arbuscular mycorrhizal fungus (AMF), while the organic biostimulant was seaweed extract. Each treatment had 50 plantlets in triplicate. The results demonstrated that the treatment of biological and organic biostimulants increased plantlet survival rates during acclimatization, beginning 2 months after application and remaining consistent for 4 months. The biological stimulant application produced the highest plantlet survival rate (>94%). Based on how quickly the plantlets transitioned to the next stage, it was discovered that after 2-months incubation, most of the plantlets had already transferred to the second phase of acclimatization (opened tunnel). After 4-months incubation, the biological stimulant treatment produced the most plantlets at the later stage. However, throughout the 4-month acclimation period, more plantlets were transported from the pre-nursery to the main nursery, particularly with the use of organic biostimulants (56-64%). Keywords: arbuscular mycorrhizal fungi, plantlet, survival rate, seaweed

Abstract

Numerous operational variables constantly threaten small-scale fishery enterprises, increasing vulnerability and the possibility of economic stagnation. The goal of this study was to investigate the vulnerability of small-scale fishery enterprises in Central Tapanuli Regency. The study looked at six aspects of vulnerability: natural, human, physical, financial, social, and institutional. The methodology employed was participative, using interviews, observations, and Likert scale questionnaires. The study's findings revealed that seasonal and weather circumstances were the most significant weaknesses affecting fishery enterprises. Except for the marketing group, which showed a greater degree of vulnerability was visible in terms of institutional supporting and participation by fishermen's groups. Finally, fishery enterprises can improve their resilience by developing business groups and implementing treatments tailored to each group's individual needs. This study proposes technical methods to increase the resilience and sustainability of the region's fisheries enterprises. Keywords: Central Tapanuli, fisheries business, resilience, vulnerability

Abstract

The information related anatomical characteristics (cell dimension and proportion) of Acacia aulacocarpa is still limited also for its axial and radial variations. This research aimed to analyze variation of the anatomical characteristics in axial and radial direction. Three trees of 27-year-old A. aulacocarpa planted in Gunung Kidul Yogyakarta were used. This research covered a completely randomized design with two factors, the axial direction (base, middle, and top of the trunk) and the radial direction (near pith, between pith and bark, and near bark) in triplicate. A two-way analysis of variants was used. The measured parameters were fiber dimensions (length, diameter, lumen diameter, and wall thickness) and cell proportions (fiber, vessel, ray parenchyma, and axial parenchyma). The results showed that average value of fiber dimensions was as follow: fiber length 0.94 mm; fiber diameter 17.43 µm; lumen diameter 11.75 µm; and fiber wall thickness 2.84 µm. The average value of cell proportions was 52.48% of fibers cell proportion; 17.5% of wood vessel proportion; 15.69% of axial parenchyma proportion; and 16.68% of ray’s parenchyma proportion. The axial position factor does not affect the proportion and dimensions of the fiber. However, the radial position factor affects the proportion of fiber cells, the proportion of wood vessels, the proportion of axial parenchyma, fiber length, lumen diameter, and fiber wall thickness. Fiber length, fiber lumen diameter, cell wall thickness increased from near the pith to the middle and then remained relatively constant toward the bark. Based on these results, it is suspected that the middle and near the bark are mature wood. Keywords: Acacia aulacocarpa, cell dimension, cell proportion, radial direction, axial direction

Abstract

Chili is one of the horticulture crops with the highest commercial value. Farmers can cultivate chili in intercropping systems with water spinach plants as a land-saving alternative. The purpose of this study was to determine the optimal chili planting distance and water spinach planting timing for increasing chili plant growth in chili-water spinach intercropping cultivation. A factorial randomized group design was adopted in this study. The first consideration was the spacing between the chili plants, which measure 50´70 cm and 50´50 cm, respectively. The second aspect was to plant water spinach at the same time as chili, one week after planting (1 WAP) chili, and 2 WAP chili. The findings indicate that optimum spacing and planting time for water spinach can improve the growth of chili plants. When chili plants were spaced 50´70 cm apart, their height and number of leaves increased dramatically. When compared to other treatments, the planting time of water spinach 1-2 WAP chili resulted in significantly higher plant height and number of leaves. All growth variables examined were significantly influenced by the interaction of 50´70 cm and water spinach planting time 2 weeks after chili planting. Keywords: chili, intercropping, planting distance, planting time, water spinach

Abstract

Soybean cultivation in tropical regions, such as Indonesia, is often constrained by photoperiod sensitivity, resulting in low yield. Using long juvenile traits in short photoperiod tropical areas resulted in lines with late flowering time and high yield. Genetic diversity analysis of soybean lines using molecular markers is a critical step for breeding high-yielding soybean lines. This study aimed to analyze genetic diversity and construct DNA barcodes for 44 tropical soybean superior lines based on 17 SSR markers. Genetic materials used were the high-yielding F5 soybean lines developed for their adaptation to short day-length of low latitude tropical regions. SSR markers used were those that distributed well across the soybean genome and proven their usefulness for soybean genetic diversity analyses. Results showed that the SSR demonstrated distinctive polymorphism among the 44 lines. A total of 377 alleles were detected with an average of 22.8 alleles per SSR locus. Polymorphism information content (PIC) values varied from 0.77 to 0.96 with an average of 0.90. Phylogenetic analysis showed that the 44 soybean genotypes were divided into 2 main clusters. Five markers, i.e., satt009, satt646, satt147, satt431, and satt191, with a polymorphism information content value of ≥0.94, were found to be informative and suitable for DNA barcode construction. Each of the 44 lines was assigned with specific barcodes. The barcodes constructed from this study should be useful for DNA fingerprinting as well as protection purposes of the specific superior soybean lines analyzed in this study.

Abstract

The goal of this study is to compare the performance of Seasonal Autoregressive Integrated Moving Average (SARIMA) and Bagging Exponential Smoothing (BES) models for forecasting red chili production. The secondary data used in this study came from BPS-Statistics Indonesia and the Ministry of Agriculture. The data include monthly national-level red chili production from January 2013 to December 2021. Data is analyzed using time series approaches such as SARIMA and BES. The performance of both systems was compared, and production forecasts were created using the best model. According to the research findings, for this dataset, the SARIMA (1,1,1)(0,1,1)12 technique outperforms the BES method since it has lower MAPE and RMSE values, 7.06 and 95,473, respectively. The best model was then applied to anticipate red chili production from January to December 2022, resulting in a highly accurate MAPE of 5.39. Keywords: Bagging Exponential Smoothing, red chili production, SARIMA

Abstract

Agricultural Equipment and Machinery Services Business (UPJA) is a rural economic entity that provides services to improve farming equipment and machinery (alsintan). UPJA's good performance will satisfy consumers (farmers). The purpose of this survey was to discover how satisfied farmers were with UPJA services. The method employed was descriptive, with IPA-Kano integrated analysis. The data was gathered through interviews and the distribution of questionnaires to 90 UPJA clients from three classes: Beginner, Developing, and Professional. The results revealed that clients were Quite Satisfied in the Beginner class, Very Satisfied in the Developing class, and Satisfied in the Professional class. The Beginner class's priorities for increasing service were the diversity of machinery, its adequacy, and the number of staff. In the Developing and Professional classes, advertising attributes, personal protective equipment utilization, and team member uniforms were prioritized for service improvement. Keywords: agricultural tools and machinery, farmers’ satisfaction, UPJA

Abstract

Edible wild mushrooms (EWM) are food sources which have high nutritional value. Although they are not the main choice of daily foods in Indonesia, various local communities and mushroom foragers have been consuming EWM for decades, yet without proper documentation. This study aimed to preserve the knowledge of EWM consumption to increase the popularity and public awareness of EWM as alternative food in Indonesia. Data was collected via a structural survey to 50 mushroom hobbyists with range of 18-50 years old and representing several ethnic groups in Indonesia: Javanese, Malay, Sundanese, Banten, and Bugis. Most of the respondents have consumed EWM for more than 5 years, with a frequency of consuming more than once per month, and the knowledge of foraging was obtained from their families. The edible mushrooms were collected mostly after every January and usually consumed by themselves. The location for mushroom seeking and species of EWM mostly were the forests around residence area and Termitomyces spp. (local names: ‘jamur barat’, ‘jamur bulan’, ‘jamur rayap’, ‘jamur trucuk’, ‘jamur sempagi’, respectively). The taste of mushroom was the main reason for forage activity among the hobbyists. They generally consumed all parts of basidiomata and preferred the soft texture of fruiting body. The soup dish was the most preferred by foragers, in contrast to fried cooking type. Most of them distinguish EWM from poisonous mushrooms by observing certain structures basidiomata, however, cases of wild mushroom poisoning have occurred among foragers with low occurrence of frequency.

Abstract

Indonesia's marine area is around 70%, so seaweed is extensively cultivated in Indonesian waters. Although seaweed cultivation is thought to be simple, farmers confront numerous challenges. Poor farmer competence leads to low production quality, low product selling price, no negotiating position, inability to maintain production capacity, and lack of competitiveness. The purpose of this study was to assess seaweed farmers' production performance and competency. This study was undertaken in Bantaeng Regency, one of South Sulawesi Province's seaweed production centers. The Slovin algorithm was used to determine the number of respondents, which was 125 farmers. The method was Simple Random sampling. Descriptive analysis was used to describe seaweed farmers' performance and competence, whereas Kendall W Correlation analysis was used to determine the relationship between farmer attributes and seaweed farming competence. The results revealed an average dried seaweed yield of 3,390 kg per hectare. Seaweed farmers have a high level of technical competence in operating their farms, with a total score of 13,262, however managerial competence is poor, with a total score of 5,334. The association between farmer characteristics and agricultural competence demonstrates that age has a very strong relationship, as do education, farming experience, family dependents, and land area. To increase seaweed production and income, the government must develop an integrated extension program that improves farmers' technical and managerial skills. Keywords: farmer performance, managerial competence, seaweed, seaweed production, technical competence
