Abstract

Prices of agricultural products and poverty relationship are the two types of standing issue to solve. This paper tries to argue that price of agricultural products (hereafter, agricultural price) and poverty are strongly related. We employed Correlation (intermediate step) and Path (final step) in the analysis procedure. The results show that, first, the association degree between agricultural input (note as well, that price is crucial factor to get input) with poverty approaching 70%, indicating that agricultural input is good-fit in explaining poverty.  Second, the higher the frequency of getting agricultural extension, and price information for various inputs (and output) in agriculture, the higher the crop productions (agricultural sector, in broad sense) will be gained.  This indicates these two variables (inputs-outputs prices) can also be expected to be important instruments in increasing smallholders’ income and in turn help them living above poverty line.  Farmers household income is strongly affected by prevailing market price. Agricultural price is functioning as intermediate part of income calculation. It is clear that price of agricultural products has a strong linkage with rural poverty alleviation in the country.

Abstract

Potato production in Indonesia has been declining while demand for potatoes remains increasing. One main reason of the decline is the lack of availability for good potato seedling. To optimize the growth of potato seedling, some plant extracts as exogenous growth regulators may be used. This experiment was aimed to select the best plant extract as exogenous growth regulator for potato seedling growth and study the underlying physiological process. Seven plant extracts as exogenous growth regulators for potato seedling were used as treatments namely: water as a control, corn grain (Zea mays L.), onion (Allium ascalonicum L.), coconut water (Cocos nucifera L), snaps (Phaseolus vulgaris L), banana (Musa paradisiaca L.) and mung bean sprouts (Vigna radiata). The experiment was set in the form of randomized complete block design with three replications. Result revealed that one month after sowing, corn grain extract gave the best quality on the potato seedling growth based on percentage of live seedling (100%), seedling height (15.87 cm), number of leaves (9.40 leaves) and root length of the seedlings (13.39 cm). On the other hand, water treatment (control) showed the lowest growth quality on potato seedling indicated in all parameters as follow: percentage of life of potatoes seedling (74.44%), seedling height (3.66 cm), amount of leaves (4.27 leaves) and length of root (4.83 cm).

Abstract

Smart irrigation system is an automatic irrigation and monitoring system on agricultural land with a sensor, automation, and control technology based on the Internet of Things (IoT). This system can reduce the agricultural activities that were previously performed manually into an automatic system with a reduced human supervision. Smart Irrigation systems that are widely developed used Arduino as the controller. Arduino still lacks in response, low durability, and sensitivity to temperature change, hence requiring frequent maintenance to avoid weather disturbances, insects, and others. This paper presents a development of a smart irrigation system using a Programmable Logic Controller (PLC) as the controller and a soil moisture sensor as a humidity condition measurement tool. The advantage of using PLC as a controller is more stable and has sensor compatibility with higher accuracy. Hence the results are more consistent and accurate. The PLC system is expandable, allowing for the inclusion of more channels for sensors and other measurement instruments. The developed system can collect data on soil moisture conditions, trigger valves, and perform auto irrigation using sprinklers, reducing or even eliminating the need for human intervention. The IoT collects data from sensors and updates the data into a database system, allowing users to monitor the land conditions in real-time. The developed system was predicted to save manpower (20%) and water usage (42.47%) compared to the conventional method. Keywords: Smart Irrigation; IoT; PLC; Moisture Sensor; Sprinkler

Abstract

A study was conducted to examine sprouting on potato seed tuber over a range ofdifferent temperature and moisture conditions. The Experiment was conducted under controlledenvironment conditions using a Terratec thermo-gradient table at the School of AgriculturalScience, University of Tasmania. The trial involved exposing seed tubers cv. Russet Burbank(grade 40-60 g) sourced from one seed lot to three water potentials (-0.6 MPa, -0.02 MPa and-0.01 MPa) at each of four different temperatures (10, 15, 20 and 25 °C). The growth mediumused in the trial was vermiculite (Grade 2, Australian vermiculite and Perlite Co-P/L). Thewater potential treatments were prepared based on the relationship of water content and waterpotential by Whalley et al. (2001). Four seed tubers were planted in each container filled withgrowth medium at a 10 cm depth and covered by the growth medium before the containerswere resealed. Using a pseudo replication design with temperature as the block, the moisturetreatments were randomized within each temperature treatment with two replicate containersfor each treatment combination. The design therefore provided a total of 8 tubers for eachtemperature and water potential combination, and a total of 24 treatment combinationsoverall. An analysis of variance and least significant difference (LSD) procedure using SPSSfor windows version 14.0 was performed to determine the response of the tuber seeds totemperature and moisture. Temperature and moisture significantly affected sprout growthrate, assessed as the sprouting capacity of the tubers (FW sprouts per FW tubers). Sproutingcapacity of seed tubers increased with increasing temperature and water potential. Therewas a significant interaction between temperature and moisture treatments on the sproutingcapacity (p<0.05). The differences between water potential treatments were greater at highertemperature, with differences between sprouting capacity of tubers exposed to dry and wetconditions particularly evident at temperatures of 20 and 25 ºC. Relation between the resultand risk in plant response to warmer climate as an impact of global warming is discussed.

Abstract

Forest management practice in Indonesia has changed from “the forest first” paradigm to “the forest second” paradigm which emphasis on balancing between ecological dynamics and social dynamics (economy, culture, and politics) in forest management. “The forest second” paradigm have been practiced in HJRE (Hutan Jati Rakyat Ecolabel or Ecolabling Community Teak Forest) program in Konawe Selatan District of Southeast Sulawesi Province, Indonesia. This paper was intended to explain the collaboration of the actors involve in the program at community level. Data used in this paper gathered from in-depth interview of various actors who have involved in this program at community level especially local people who have registered as members of KHJL (Koperasi Hutan Jati Lestari or Sustainable Teak Forest Cooperative) and actively involved in the program. These people selected as informants from 8 villages where this study conducted. Beside that, it was interviewed also other actors involved in the program. This study revealed that the actors involved in collaboration process of HJRE program at community level were householdmembers of KHJL, Management Unit, JAUH (Jaringan Untuk Hutan or Network for Forest), TFT (Tropical Forest Trust), Wood Industry (PT. KJL), Head of Villages, and Head of KRPH (Kesatuan Resort Pemangku Hutan or Forest Functionary Unit). All actors involved in collaboration process contributed R-O-N (Resources-Organization-Norms) capacities in the stage of development of HJRE program. Some actors contributed much or less on R-O-N or its combinations. The capacities contributed of the actors gradually from social initiation/ awareness stage up to expansion and sustainability stage were R/N – O/N – R – R – N/R.Degree of collaboration of the actors involved in the HJRE program were not the same. Some actors have high collaboration and some low collaboration. These situation determined by the power and interest of the actors.

Abstract

Three series of plant growth regulators experiments in Chrysanthemum tissue culture, each arranged in completely randomized design (CRD), were studied to formulate efficient plant regeneration system for developing Chrysanthemum plant cell engineering. In the first experiment, 100 mg callus were cultured in liquid Murashige and Skoog (MS) medium supplemented with different combinations of NAA and BAP concentrations treatments. After 30 days of culture, heaviest callus (1.55 g) was obtained in NAA (1.0 mg L-1) + BAP (0.5 mg L-1). Consequently, shoot regeneration experiment with different kinds and concentrations of auxin, i.e. NAA and 2iP were each combined with different concentrations of cytokine BAP. Callus grown on solid MS medium supplemented with both NAA and BAP at 0.5 mg L-1 showed fastest shoot initiation (30 days), largest number of shoots (5 shoots), longest shoot length (2.88 cm). While combination of 2iP (0.5 mg L-1) and BAP (2.0 mg L-1) also produced same response on shoot initiation but shorter (1.88 cm) and only one shoot. Largest number of shoots (3 shoots) was obtained in treatment BAP (0.5 mg L-1) without 2iP, although shoot initiation was slower (39 days) with shorter length (1 cm). In a separate experiment, effect of single treatment of potential synthetic cytokine for shoot regeneration, Thidiazuron (TDZ), at different concentrations was examined. However, callus grown on TDZ incorporated medium did not produce any shoots and changed from green to brown at end of study (90 days). It was assumed that TDZ inhibited formation of shoots in Chrysanthemum callus culture.

Abstract

Utilization of local food source such as nixtamalized corn flour and nike flour as base ingredients in producing snack bars may add the product value and also reduce production costs. The purpose of this study was to produce a prototype snack food bars weighing 50 grams for each bar, containing calories that meet the standards of Emergency Food Product (EFP) by 233 kcal/bar, and being favored by consumers. Snack food bars produced in this study used the formulation in the previous study, consisted of 26.77% nixtamalized corn flours, 6.69% nike flours, 9.37% corn starch, 20.08% chocolate, 13.01% margarine, 13.38% egg whites, and 13.38% sugar. Snack food bars were produced through six steps: weighing ingredients, mixing, molding, baking in the oven, cooling, and packaging. The baking process used three combinations of temperature and time, each with 3 replicates. Bars were baked at 1000C for 20 minutes, and then followed by temperature of 1400C (treatment A), 1500 C (treatment B), or 1600C (treatment C) for 40 minutes. Snack food bars produced by baking temperature combination were less preferred by the panelists based on the taste attributes due to the distinctive flavor of nike flours persisted in the bars. Baking temperature C (at 1000 C for 20 minutes, followed by 1600C for 40 minutes) got the highest score based on the texture attributes. The nutrient and calorie content of snack food bars produced did not show much difference with the formulation result. Snack food bars produced in this study contained 10.1751 g fat, 3.5694 g protein and 32.2681 g carbohydrate in every 50 g of snack bars. Based on the formulation result, snack food bars contained 9.8 g fat, 5.84 g protein, and 30.37 g carbohydrate per 50 g of snack bars. Snack food bars produced in this study contained 234.926 kcal per 50 g of snack bar while based on the formulation result, snack food bars contained 233 kcal per 50 g of snack bar. This implies that Snack food bars based local product has the potential to developed in the regional in security food in the face of emergency condition.

Abstract

Potable water with high quality is a basic requirement for human wellbeing. However, the perceptions on the quality of potable water sources and associated factors influencing the later have not been well studied. Hence, this study aims at examining the perception of water quality in rural/agricultural areas of Machakel district, North West Ethiopia. The study used cross sectional survey design. structured interviews with 293 sample respondents, who were selected using probability sampling technique, were conducted to capture their views on water quality at the source. Descriptive statistics and ordinal logistic regression were used to identify factors affecting the perception of households on water quality in rural/agricultural areas. Most of the household heads used protected hand-dug well, protected spring and protected shallow well. Variables such as education, income, past experiences of health risks, chemicals (chlorine) and poor trust in supplier have a significant effect on perception of rural agricultural communities on water quality at the source. The study suggests education and chlorination of water sources to be promoted among the rural/agricultural communities to enhance better quality perception on potable water sources. On the other hand water quality control systems should be created to avoid health jeopardy from water born sickness. For high income groups it may be better to provide access to pipe water. User participation should be considered in the process of water source construction.

Abstract

Local rice is rice that has been cultivated for generations by the community and commonly cultivated without using chemical inputs. Endophytic fungi are fungi that live in the plant tissue and does not cause disease symptoms in the host plants. This study aimed to molecular identifying isolates of MDTA and MDTB endophytic fungi which have been isolated from the local Pulu Mandoti rice plant tissue and growth test on the four types of culture media those were synthetic PDA, natural PDA, MPA, and MEA. The fungi DNA isolation using DNesay Kit. DNA sequencing analysis using the mega BLAST program showed that the MDTB fungus has similarities to Podoscypha bolleana strain 32034 no accession JQ675334 and Podoscypha bolleana strain 32032 no accession JQ675332, whereas the MDTA fungus has similarities to Coprinopsis cinerea A2S3-5 isolate and Coprinopsis cinerea strain CNRMA / F 07-32. The best culture media and sporulation of endophytic fungi is MPA media. This research is the first study to molecular identifying with endophytic fungi from local rice and viability test on the four types of culture media. The results of this study contribute to the diversity of local rice endophytic fungi in Sulawesi.
