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).

Abstract

Black rice is a functional food so that it is not only to meet food needs, but also to maintain the health of consumers. For farmers, producing black rice will be more profitable because the selling value is higher than other types of rice. However, not many consumers and farmers are aware of this, resulting in unstable black rice production. In this free trade era, the opportunity to export a commodity or penetrate the international market is getting bigger. Therefore, it is necessary to study the competitiveness of black rice to determine its potential.The purpose of this research was to identify competitiveness through competitive advantage and comparative advantage as well as the impact of government policies. The research design used was quantitative with survey techniques. Data were analyzed using the Policy Analysis Matrix (PAM). The results showed that black rice was competitive both competitively and comparatively, indicated by the value of PCR < 1 = 0.568 and DCR < 1 = 0.521. Therefore, 1) black rice farming was efficient financially and economically, and 2) black rice has the potential to be exported. The impact of government policies on black rice farming has overall reduced farmers' income. In addition, government policies also inhibited black rice exports as indicated by the value of NPCO < 1 = 0.793 and prevented farmers from exporting inputs as indicated by the value of NPCI < 1 = 0.565.

Abstract

This study aims to examine the effectiveness of gibberellins in breaking dormancy to produce high viability snakefruit (Salacca snakefruit Geartner) seeds. The materials used are snakefruit seeds from Tamareja Village, Donggala Regency, sterile sand media, aquades, and GA3 solution. This research was arranged using a completely randomized design (CRD) with one factor, namely the provision of gibberellin, consisting of five levels of concentration, namely P0 = control (without treatment), P1 = 30 ppm and P2 = 40 ppm P3 = 50 ppm P4 = 60 ppm. each treatment was repeated five times so that there were 25 experimental units. Each experimental unit used 20 seeds. Observation data were analyzed using analysis of variance (ANOVA), followed by Tukey' HSD test if the treatment tested showed a significant effect. The results showed that gibberellin administration effectively broke snakefruit seeds' dormancy and produced seeds with high viability. The higher the gibberellins' concentration would increase germination speed plumule length, radicle length, and faster embryo axis emergence. Gibberellin 60 ppm resulted in germination power 98%, germination rate 20.97 days, plumule length 5.52 cm, radicle length 5.15 cm, and embryo axis emergence 9.2 days.

Abstract

Low of relations between farmers and the market causes the marketing of vegetable commodities to not run optimally. The relationship between various marketing agencies and farmers produces a social network. Based on this, the social network in the marketing aspect is the main capital for the development of farming. The objectives of this study were (1) to identify the characteristics of farmer members of the Katenzo Farmers Group, (2) to analyze the structure of the social network on the marketing aspects of vegetable commodities in the Katenzo Farmer Group, (3) to analyze the position of actors in social networks on the marketing aspects of vegetable commodities based on the degree of centralism. at the Katenzo Farmers Group. This study used a qualitative research design with a case study approach. Samples were taken using census techniques to all member farmers, amounting to 13 people. The analysis method used is Social Network Analysis (SNA). The results of this study indicate that all respondents are male farmers who are included in the category of young farmers who have an average high school education level and have business experience under 5 years. The network structure that is formed is a personal radius network structure (Radial Personal Network), with the central actor is the Head and Public Relations Division of the Katenzo Farmers Group.
