Abstract

ABSTRACTThis study aims to identify the use of energy sources at the stage of the paring process,calculate the total energy used at the stage of the paring process and calculate the energyefficiency in this case, the efficiency of drying at the paring drying process. From the results ofthis study found the total energy used for paring drying at PT. Royal Coconut Airmadidi of22,808,070,020,500 joules. While the drying efficiency was found to be 33.2%, it means that outof 100% of the energy expended, only 33.2% was actually used in the paring drying process.Keywords: Energy Analysis, Paring Drying.

Abstract

SUMMARYThis research aims to determine the effectiveness of the use of secondarymetabolites of Metarhizium and Beauveria fungi by infusion of roots in clove plantsagainst H. semivelutina larvae. The results of the study are expected to benefitfarmers in controlling H. semivelutina pests with secondary metabolites of thefungus Metarhizium and Baeveria in clove plants by means of a root infusion.The study was conducted in a clove plantation area owned by farmers in TonsawangVillage, Tobatu District, Southeast Minahasa Regency, North Sulawesi. Theresearch lasted for 3 (three) months, from February to April 2020. This study useda Randomized Block Design (RBD) method on farmers' clove plants.Determination of plants that will be applied to the root infusion is done by lookingat plants that are attacked by H. semivelutina pests by looking at the hole that emitsliquid mixed with feces in the clove plants in Tonsawang Village, Tombatu District.In this study using secondary metabolites of Metarhizium fungus and Beauveriafungus in H. semivelutina pest control by means of root infusion.The results showed that the average effectiveness of the use of secondarymetabolites in controlling H. semivelutina reached 78.52%, with a percentage ofeffectiveness of the secondary metabolite of Metarhizium fungus at 81.05% whichwas not significantly different from the secondary metabolite of Beauveria that was75.59%, but significantly different from the control of 10.57 %.Keywords: Effectiveness, secondary Metarhizium metabolites of fungus,Beauveria, H. semivelutina, Tombatu.Keywords: Effectiveness, secondary metabolites of Metarhizium fungus,Beauveria, H. semivelutina, Tombatu.

Abstract

ABSTRACTWater has a very important role in life because all living things in this world need water.Plants and animals are mostly composed of water. Plant cells contain more than 75% waterand animal cells contain more than 67%. Less than 0.5% of water can be used directly forhuman purposes. Less than 0.5% of water can be used directly for human purposes. Thepurpose of this study was to determine the Talawaan irrigation water quality associated withSodium Adsorption Ratio (SAR) in Talawaan District, North Minahasa Regency. Talawaanirrigation water quality in Talawaan District includes SAR parameters in the TertiaryIrrigation Channel (1) of 1.56 me / L and SAR in Tertiary Irrigation Channels (2) of 0.92 me /L meets the requirements of irrigation water quality in the good category.Keywords: Water Quality, Sungai Talawaan, Irigation Water

Abstract

ABSTRACTGolden snail (Pomacea canikulata L.) or also known as mulberry snail is one of the main pestsof rice plants in North Sulawesi, including in the City of Tomohon. This golden snail pest likesyoung rice plants with the intensity of damage varies from 10-100% depending on the level ofpopulation on each land. This pest destroys plants by grating plant tissue and eating it. In responseto help the problems faced by farmers, research has been carried out on the population of thegolden snail pest (Pomaceacaniklata L) in bait and traps on lowland rice plants (Orzya sativa L).The purpose of this study was to determine the effect of the use of papaya leaf baits and watertrench traps on the population of golden snail pests on lowland rice plants. The study wasconducted in Taratara 1 Village, West Tomohoon District, Tomohon City. The duration of thestudy is approximately four months, which took place from March to May 2020. The researchmethod was carried out by quantitative descriptive methods with direct experiments in the field.This experiment uses two lowland rice fields consisting of bait and trap. Observations were madeat the age of plants 21 days after planting, 28 days after planting, and 35 days after planting. Theresults of the research on the treatment of bait using papaya leaves an average of 24.8 individuals/ m2 and on the treatment of traps using an average water trench of 31.4 individuals / m2. Thepopulation of golden snail pests in both treatments decreased from plants aged 21 days afterplanting to 35 days after planting. The age factor in plants can increase the height of golden snailpests. Gold snail can easily attack plants by grating the plant tissue and eating it. Because thestructure of the stems, stems, and leaf blades in the plant is still young. Both treatments contributeto positive results, so that further research is needed by combining bait and trap treatments on alarger scale and can be integrated with other environmentally friendly control methods.

Abstract

ABSTRACTThe research aims to determine the effect of compost on soil porosity of sandy loam and claysoils and to see its effect on the growth of Maize plants. This research was conducted at Greenhouseand at Soil Physics and Soil Conservation Laboratory from May until June 2017. The results showedthat the addition of compost to soil can increase soil porosity and also the addition of compost to clayeytextured soil increased the porosity compared to the sandy loam textured soils. Application of composttends to increase plant height and dry weight on all age of plants; i.e. 10 days after planting, 30 daysafter planting and 40 days after planting. Application of compost at a dose of 10 tonnes/ha gives thehighest plant height on sandy loam soils and the heaviest plant dry weight on clayey loam soils.Keywords:Compost, Porosity

Abstract

ABSTRAK Chili (Capsicum annuum L.) is one of the horticultural commodities which is classified as a vegetable and is most widely cultivated in Indonesia. In addition, chilies contain minerals such as iron, potassium, calcium, phosphorus and niacin. Tricho-compost is a fertilizer derived from organic materials containing the antagonistic fungi Trichoderma sp. Tricho-compost as fertilizer is able to provide nutrients in the soil for plants. Plant Growth Promoting Rhizobacteria (PGPR) is a group of soil microorganisms that live and develop well in soils that are rich in organic matter and which are beneficial because they can spur plant growth and production. This study aims to determine the effect of the application of Tricho-compost and PGPR (Plant growth promotion rhizobactery) biological agents on the vegetative growth of chili plants. This research was conducted at the green house of the Faculty of Agriculture, Sam Ratulangi University (UNSRAT) Manado. The study lasted for 3 months using RAK (randomized block design) with 4 treatments, namely Control (NPK), Tricho-compost, PGPR (Plant Growth Promoting Rhizobacteria) and Tricho-compost added with PGPR (Plant Growth Promoting Rhizobacteria). Observation of growth parameters in the form of plant height, number of leaves, number of branches and stem diameter. Growth is carried out every week and starts at 2 week after transplanting until the plants are 2 months old. The results showed that the application of Tricho-compost and PGPR treatments given together gave the largest number of branches, number of leaves and stem diameter, while the parameters of height the largest plants were produced in the Tricho-compost treatment, although sta
