SUMMARYYonni Oktavio Balompapung, 14031108021 (2021) Application of Biochar and CowManure on Growth of Red Spinach Plants (Amaranthus Tricolor L). Under theguidance of Dr. Ir. Verry Ch. Warouw, MS as Chairman and Dr. Ir. Lientje Th.Karamoy, MSi as Member.This study aims to examine and find out how much influence the application ofbiochar and cow manure on the growth of red spinach (Amaranthus Tricolor L)plants. This research was conducted in Kakaskasen Village, North Tomohon District,Tomohon City. For pot experiments, soil analysis and cow manure were carried out atthe Laboratory of Chemistry and Soil Fertility, Department of Soil, Faculty ofAgriculture, Sam Ratulangi University, Manado. This research was conducted using acompletely randomized design method consisting of 7 treatments with 5 replicationsin order to obtain 35 experimental pots, where soil control (KT), soil biochar control(KTB) and A, B, C, D, E as mixed growing media biochar and cow manure accordingto the dosage.The results of this study indicate that the application of biochar and cow manureaffects the growth and production of red spinach (Amaranthus Tricolor L.) in thiscase plant height, plant fresh weight and plant dry weight.

Abstract

ABSTRACTSexava coriacea L. is a major endemic pest that attacks the leaves of coconut trees in WestHalmahera district and can cause damage so that plants cannot produce fruit and can cause plantdeath if severe attacks. This study aims to determine the level of damage and population density ofS. coriacea pests in coconut plantations in Tongutesungi Village, Ibu District, West HalmaheraRegency. The research was carried out in the coconut plantation area of Tongutesungi Village, IbuDistrict, West Halmahera Regency. Observation of the level of damage to S. coriacea was obtainedby taking five affected leaf sheaths by cutting them to drop them on the ground, then observing thedamage to coconut leaves. The number of fronds observed was 5 times 20 sample plants per 100fronds, so that the total observed fronds were 100 times 5 observation points, namely 500 fronds.Observation of population density of S. coriacea per sample tree was determined by directlycounting the number of insects both nymphs and imago found in coconut leaf midribs. Observationof population density was 4 fronds x 20 sample trees multiplied by 5 points. The observation areawas 400 fronds. The population density of S. coriacea was determined by obtaining the averagevalue of all observational data. The results of the study on the level of damage to the samplingleaves of coconut trees attacked by S. coriacea were 65.07% - 67.32% (> 50-75%) and very heavy79.19% - 81.21% (> 75-100) the average level of damage reached 65.07% - 81.21% or the averagelevel of damage from all observation locations was 74.71%. The population density of S. coriaceamidrib at all observation locations ranged from 1.87- 3.01 individuls/midrib with an averagepopulation density of 2.45 individuals/midrib.Keywords : Sexava coriacea L., Cococ nucifera L., degree of damage, population density

Abstract

ABSTRACT This research aimed to observe the effects of distributing goat manure on marginal soils with indicators of water spinach. It was conducted in pot experiment using goat manure treatment which consist of 0 ton/acre as control, 10 ton/acre; 20 ton/acre; 30 ton/acre and Phonska 300 kg/acre. There were 2 plants per hole. Incubation period of the goat manure was 2 weeks long. This research was done in 2 month. Research method used was a Completely Randomized Design (CRD) and 3 repetitions. Variabels analyzed were plant height, number of leaves, and wet basis of water spinach. Statistical test for the tabulated data was run by using Analysis of Variance (Anova) and Least Significant Difference (LSD). The result of this research showed that goat manure treatment has no real affect on the plan height, number of leaves and wet basis of water spinach, but there is a tendency from each goat manure treatment.

Abstract

ABSTRACT This study aims to identify the agroforestry patterns applied by the people of Kambo Village, Palopo City and describe local wisdom in the application of the agroforestry system. This research was conducted in June 2020 in Kambo Village, Palopo City, South Sulawesi. This study used a purposive sampling method by determining the criteria in selecting respondents, namely the respondent is the original community of Kambo Village, the respondent manages agroforestry land, and the respondent is a member of a farmer group Sehati. The results of research on local wisdom in the agroforestry system applied by the community in Kambo Village show that the agroforestry patterns applied by the Kambo Village community are agrisilviculture and apiculture patterns and in the application of the agroforestry system the community still maintains local wisdom that has existed and developed from generation to generation, where It can be seen in some of the activities carried out by the community, such as in seed preparation to harvesting, which still retain the knowledge passed on by their parents for a long time.

ABSTRACTNutrients of nutrients are important factors for plant growth which can belikened to food substances for plants. Plant nutrient contents of N, P, and K in themining area of Talawaan Village was studied in this research. Soil samples from threedifferent places at the mining site were taken and analyzed at the Laboratory ofChemistry and Soil Fertility. Analysis of plant available Nitrogen utilized Kjedhalmethod and plant available P and K used Bray 1 method, The findings show that theplant available nutrient of N, P and K is classified from low to very low, while soil pHof the Talawaan Village Mining area is neutral. It is suggested to increase the nutrientavailability for plants in this location by adding organic fertilizers.Keywords: Plant available nutrients, Nitrogen, Phosphorus and Potassium

Abstract

AbstractThe purpose of this study is to know how rainfall affects soil erosion without mulch and soil erosion with mulch treatment.It is one of the resources that play an important role in the survival of organisms. Rainfall is one of the great climatic elements thatplay a role in avalanches and erosion (sutedjo and kartasapoetra, 2002). Rainwater that falls on the earth will result in erosion ofthe soil in its path. One of the techniques for land and water conservation is that of mulsa (pratiwi, 2007). The method used in thisstudy is a secondary data analysis method. The number of data studied by as many as 34 samples through simple, linear regressionanalysis methods. Studies suggest that there is a tendency that the higher the precipitation, the more soil erosion is produced. Asfor the linrelation equation, it is Y1 = - 1304.4+ 81.411X with r efficiency = 0986 and Y2 = 58,891X - 933.26 with an r.0,985.Research obtained a value of significance by as high as,000 < 0.05; It could be concluded that the hypothesis (h1) that reads "rainfallhas a positive effect on erosion with and without any kind of mulch," is accepted. Regression coefficient effect of rainfall on erosionwith mulsa treatment is y2 = 81.411-22.5. Can be seen that the regression coefficient of dx is <001. This shows very clearly thecontrast in mulched soil erosion, its erosive drop by as much as 2.2.5 grams.Keywords: Rainfall, Mulch, Erosion.

Abstract

ABSTRACTThis study aims to study the daily behavior of adult maleo birds in captivity in the Bogani NaniWartabone National Park area. This research was conducted in December 2019. There were 6maleo birds observed consisting of 3 males and 3 females who were placed in cages covering anarea of 20x25 m2. Observations of maleo bird daily behavior were carried out for two weeks,starting at 05.30-10.00 in the morning at 12.00-14.00 and in the afternoon at 15.00-18.00observations were made directly. Each maleo bird behavior included in the observation variablewas observed at time and duration (hours). The results of this study indicate that maleo birds arediurnal birds where the behavior of maleo birds in captivity is social behavior 68.54% morningand afternoon eating behavior 20.16% and resting behavior 11.30% and behavior of femalemaleo birds in captivity. In captivity, social behavior is often done 70.20%, while eatingbehavior in the morning and afternoon is 18.30% and resting behavior is done by maleo birds atnoon and 11.50% in the afternoon.Keywords: Maleo, Daily Behavior, Bogani Nani Wartabone National Park.
