Abstract

The highest decrease in the number of food crop workers occurred in Java, as many as 2,87 million people in 2007-2014. The age of food crop agriculture workers in Java is dominated by workers aged over 45 years (64,95%). If there is no addition of new workers, then the food crop labor will be increasingly dominated by old age groups which will make it difficult for the agricultural sector to carry out its mandate to improve and maintain sustainable food security. The purpose of this study is to describe the condition of the food crop agriculture subsector from the aspect of labor absorption in Java for the period 2007-2014 and analyze the effect of the regional GDP of food crops subsector, real wages, education, and land area to the absorption power of agricultural food crops subsector on labor in Java. Central Java Province is a province with the largest decrease in the number of agricultural food crop subsector workers compared to the other four provinces on Java island. From the results of the estimation, the fixed-effect model with cross-section SUR is chosen as the best model. The results show that the variable of regional GDP, real wage, and size of land area has a significant and positive effect on the labor absorption of agricultural food crops subsector, while education has a significant and negative effect. Overall this model able to explain variations of this phenomenon by 89,32%. Meanwhile, another 10,68% is explained by other variables not included in the model.

Abstract

The agricultural sector in North Sulawesi is ranked first in its role in providing added value to the GRDP and labor. However, the rate of growth of production and labor productivity is relatively low and decreases over time. Building the agricultural sector is limited to the development of subsistence farming and increases human resources or competence in the farming business. This study aimed to identify the characteristics of farmers in North Sulawesi. The results of the descriptive statistical analysis using demographic, socioeconomic, and socio-cultural variables of farmers indicate that the quality of human resources in the agricultural sector in North Sulawesi is relatively low. Thus, government policies to improve the quality of the agricultural sector's human resources is urgently needed.

Abstract

Urban agriculture grows increasingly in tropical countries. It develops not only to feed the growth of the population but also to provide green space, biodiversity, and recreational landscaping. However, developing urban agriculture is facing the problem of water provision. This study examines the existence of agricultural land in Palu, investigates the distribution of agricultural land use in each district, and analyzes the status of environmental carrying capacity for provisioning water. The environmental carrying capacity for provisioning water was assessed based on ecosystem services analysis. The total area of agricultural land in Palu is 5,892.06 ha or about 16.52% of the total area, which spreads in all districts. Three districts recorded have the more extensive agricultural lands, Mantikulore, Tawaeli, and North Palu, of each, has 2188.12 ha (14%), 1090.89 ha (18.51%), and 723.88 ha (12.29%) respectively. The status of water carrying capacity ranged from moderate to high levels, covering an area of ​​5,189.95 ha or 88.08% of the total area of ​​agricultural land. The low carrying capacity of water provision covers ​​689.31 ha or about 11.84% of the total agricultural land. The district of West and South Palu calculated to have the highest carrying capacity. However, both districts experienced a decrease in agricultural land space due to urban development. This study's finding contributes to essential data for relevant authorities in decisions making for sustainable development of urban agriculture in Palu.

Abstract

Mold are multicelular -microscopic fungi known as heterotrophic-cosmopolitan organism which exist almost at any place in the environment. Textiles, particularly those composed of natural organic such as jeans are easily colonized by mold. Till time, there is no report ever found regarding fungal of moldy jeans in Indonesia. This study aimed to isolate fungi from moldy jeans, identified, and described it. The result revealed that the isolate studied was Chaetomium globosum, by using several macroscopic and microscopic characters. However, since Chaetomium are known as species complex fungi, further observation is needed using molecular approach. Therefore, author consider that the isolate should be treated as Ch. globosum sensu lato for time being. Interestingly, Ch. globosum was frequently reported as endophytic fungi, which pose the potency to be used as biocontrol and bioinducer in agriculture. Further research is needed to test the isolate potency as plant pathogenic biocontrol and plant growth inducer.

Abstract

Production and management technologies are needed to produce great seeds. This study aims to obtain the location and length of time to store upland rice seeds. The study was conducted in Tamarenja and Kalukubula villages. Germination testing was carried out at the Seed Science and Technology Laboratory of the Faculty of Agriculture from May to December 2019. The seeds used were newly harvested seeds from the field. The treatment used a randomized two-factor block design. The first factor was storage locations: indoor Tamarenja, outdoor Tamarenja, indoor Kalukubula and outdoor Tamarenja. The second factor consisted of two storage times, namely: one month and two months. The treatments repeated six times, so there were 48 experimental units where each experimental unit contains 50 seeds, and the whole seeds used were 2,400. Data analysis used Fisher's test and continued with 1% Tukey’s HSD test. The results showed that the best storage location was in Kalukubula, both outdoors and indoors. The best storage time was two months. Those produced the highest germination capacity and growth potential and faster germination time, percentage of moldy seeds, and moldy sprouts.

Abstract

This research was conducted to assess different carbon sources' addition to heterotrophic bacteria's density in tiger prawn rearing media (Penaeus monodon). The research design used was a completely randomized design (CRD) consisting of 4 treatments and five replications with experimental treatments, namely: A (without giving a carbon source), B (carbon source molasses with a C/N ratio of 15: 1), C (source flour carbon with a C/N ratio of 15: 1) and D (a source of tapioca carbon with a C / N ratio of 15: 1). The test organism used was tiger shrimp PL-21 with a weight of ± 0.005 g, which was maintained with a stocking density of 100 fish / 50 liters of water for 30 days. During the maintenance of shrimp, it is given pellet type feed with a frequency of three times a day, as much as 3% of the shrimp biomass. Providing bacterial activation is carried out every ten days with organic carbon sources every day in the morning and evening. The results showed that the group of microorganisms identified as Bacillus sp. diatoms, ciliates, copepods, Paramecium sp., Synedra sp., and nematodes. Providing tapioca carbon sources resulted in the highest bacterial density (9.0  10⁷ CFU ml ). In comparison, the highest floc volume was produced by treatment with the addition of flour carbon sources (3.65 ml/l).
