Abstract

      The purpose of this study was to obtain production time efficiency on the MIFRA®22 nutmeg pericarp grater. Research at the Agricultural Engineering Laboratory, Faculty of Agriculture, UNSRAT Manado. The research period starts from March 25 to April 30, 2022. This study was designed using a completely randomized design (CRD) method with 3 treatments and 4 replications. Treatment consists of: 1). The interval of grating duration is 10 minutes, 2). The interval of grating duration is 15 minutes, and 3). The interval of grating duration is 20 minutes. Each time interval is repeated 4 times. Grated using a nutmeg pericarp grater MIFRA®22 roller grater with 250 blades. Data were tabulated and analyzed using One-way ANOVA Confidence Interval 95% and continued with 5% BNJ test (Pongoh et al, 2022). The results of calculating the best efficiency were obtained in the treatment duration of 15 minutes with an average grating time of 81.5 seconds. The calculation of the pericarp weight of grated nutmeg resulted in an average weight of 435 grams. Calculation of the weight of the flesh of nutmeg is not shredded with an average weight of 65 grams. The percentage efficiency of grating time with an average of 84.92%.

Abstract

The purpose of this study was to observe the application of organic fertilizer technology made from kipahit (Tithonia diversifolia) plants using the response of spinach (Amaranthus tricolor L.). This study used a completely randomized design (CRD) with 6 treatments, each treatment was repeated 4 times to obtain 24 experimental plants. Parameters observed were plant height, stem diameter, number of leaves, plant fresh weight and root dry weight. The results showed that the application of Tithonia diversifolia compost into the soil could increase the water storage capacity in the soil and increase the efficiency of water utilization during the plant growth period. Of the 3 organic fertilizer manufacturing technologies that have been studied, it shows that Tithonia diversifolia compost can increase the growth and yield of spinach plants, it will even be better if compost is added with poc. The application of Tithonia diversifolia organic fertilizer had a significant effect on the observed parameters. The best treatments were P5 (compost+poc from Fermentation) and P6 (compost+poc from decomposition). The administration of fermented poc showed better results than the decomposed poc and without the use of poc. The results of the new decomposition poc gave better results at week 6.Keywords: Technology; organic fertilizer; kipahit plant; spinach plant.AbstrakPenelitian ini merupakan penelitian eksperimen dengan tujuan penelitian yaitu untuk mengamati aplikasi teknologi pupuk organik berbahan baku tanaman kipahit (Tithonia diversifolia) dengan menggunakan respon tanaman bayam (Amaranthus tricolor L.). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 6 perlakuan yaitu, tiap perlakuan diulang sebanyak 4 kali sehingga diperoleh 24 tanaman percobaan. Parameter yang diamati yaitu tinggi tanaman, diameter batang, jumlah daun, berat segar tanaman dan berat kering akar. Hasil penelitian menunjukkan bahwa Pemberian kompos Tithonia diversifolia ke dalam tanah dapat meningkatkan daya simpan air dalam tanah dan meningkatkan efisiensi pemanfaatan air selama masa pertumbuhan tanaman. Dari ke 3 teknologi pembuatan pupuk organik yang telah diteliti, menunjukkan bahwa pemberian Kompos Tithonia diversifolia mampu meningkatkan pertumbuhan dan hasil tanaman bayam, bahkan akan lebih baik jika pemberian kompos ditambahkan dengan poc. Pemberian pupuk organik Tithonia diversifolia memberikan pengaruh nyata terhadap parameter yang telah diamati. Perlakuan terbaik yaitu pada P5 (kompos+poc hasil fermentasi) dan P6 (kompos+poc hasil dekomposisi). Pemberian poc hasil fermentasi menunjukkan hasil yang lebih baik dibandingkan dengan poc hasil dekomposisi dan tanpa penggunaan poc. Hasil dari poc dekomposisi baru memberikan hasil yang lebih baik pada saat minggu ke 6.Kata kunci: Teknologi pupuk organik, tanaman kipahit dan tanaman bayam.

Abstract

This experiment aims to study the effect of PGPR biofertilizer on the growth and yield of lettuce. PGPR is a group of beneficial bacteria that aggressively occupy or colonize the rhizosphere of a thin layer of soil between 1-2 mm around the root zone, PGPR acts as a biofertilizer to accelerate the plant growth process through absorption of nutrients as biostimulants and stimulate plant growth through phytohormones and as a bioprotectant to protect plants from pathogens.This study used a completely randomized design (CRD) method with 4 treatments, namely P0 (control), P1 (300 ml), P2 (75 ml), and P3 (150 ml), with 5 replications to obtain 20 experimental plants. The observed variables measured were plant height (cm), number of leaves (strands), root volume (ml), and plant fresh weight at harvest (gr).The results showed that PGPR had a significant effect on plant growth, namely plant height, number of leaves, root volume, and plant fresh weight. The highest growth and yield of lettuce were found in the treatment with PGPR   (300 ml) at the time of planting.Keywords: Lettuce, Organic Fertiliser, PGPR, Growth, and YieldAbstrakPenelitian ini bertujuan untuk mempelajari pengaruh pemberian pupuk hayati PGPR terhadap pertumbuhan dan hasil tanaman selada. PGPR kelompok bakteri menguntungkan yang agresif  menduduki atau mengkolonisasi rizosfir lapisan tanah tipis antara 1-2 mm di sekitar zona perakaran, PGPR berperan sebagai biofertilizer mempercepat proses pertumbuhan tanaman melalui penyerapan unsur hara sebagai biostimulan dan memacu pertumbuhan tanaman melalui fitohormon dan sebagai bioproktetan melindungi tanaman dari patogen\Penelitian ini mengunakan metode Rancangan Acak Lengkap (RAL) dengan 4 perlakuan yaitu P0 (kontrol), P1 (300 ml), P2 (75 ml), dan P3 (150 ml), dengan 5 ulangan  sehingga diperoleh 20 tanaman percobaan. Variabel pengamatan yang diukur adalah tinggi tanaman (cm), jumlah daun (helai), volume akar (ml), dan bobot segar tanaman pada saat panen (gr).    Hasil penelitian menunjukkan bahwa pemberian PGPR berpengaruh nyata terhadap pertumbuhan tanaman yaitu tinggi tanaman, jumlah daun, volume akar, dan bobot segar tanaman. Adapun pertumbuhan dan hasil tanaman selada tertinggi terdapat pada perlakuan pemberian PGPR (300 ml) pada saat tanam.Kata kunci : Selada, Pupuk Hayati, PGPR, Pertumbuhan dan Hasil.
