Abstract

This research aim to to know influence of giving of Atonik in so many concentration to growth of rubber seedgrafting bydm soriyt eye at stadium of stum sleep eye. Concentration the used is Atonik 0,5 ml / water litre ( A1),Atonik 1 ml / water litre ( A2), Atonik 1,5 ml / water litre ( A3), and without usage of Atonik ( A0). While treatmentof base given is same to all rubber seed. Result of research indicate that concentration of Atonik give bestinfluence and differ reality to growth of rubber seed grafting bydm soriyt eye at all of perception parameter, that isbydm soriyt length, amount of bydm soriyt diameter and leaf, compared to treatment of other concentration.

Abstract

Penelitian ini dilatarbelakangi oleh pertumbuhan dan perkembangan kelapa sawit yang sangat dipengaruhi oleh pemupukan dan ketersediaan unsur hara dalam tanah. Pemupukan kelapa sawit yang baik harus mengacu pada penerapan pemupukan dengan tepat dosis dan tepat cara. Tujuan penelitian ini adalah untuk mengevaluasi penerapan pemupukan di PT. CDM berdasarkan ketepatan dosis dan cara. Teknik pengumpulan data yang digunakan adalah observasi dan dokumentasi, lalu dianalisis dengan metode deskriptif kualitatif. Hasil penelitian menunjukkan bahwa pemupukan yang dilaksanakan sudah memenuhi kaidah tepat dosis dan tepat cara, meskipun masih kurang optimal, berdasarkan hasil observasi di lapangan. Persentase tepat dosis pupuk MOP sebesar 93,10%, dan tepat cara sebesar 95,33%.

Abstract

Ketersediaan unsur hara dapat mempengaruhi pertumbuhan, perkembangan, dan produksi tanaman. Pupuk NPK merupakan salah satu jenis pupuk yang dibutuhkan oleh tanaman kelapa sawit. Penelitian ini bertujuan untuk menganalisis tingkat korelasi linier pada produksi kelapa sawit dalam bentuk tandan buah segar (TBS) dengan pemupukan NPK. Metode penelitian yang dilakukan yaitu deskriptif kuantitatif, dengan mengumpulkan data sekunder produksi tandan buah segar dan jumlah pemupukan NPK dari perusahaan perkebunan sawit, dan melakukan analisis korelasi Pearson antara produksi tandan buah segar dengan pemupukan NPK. Dari hasil perhitungan korelasi Pearson antara produksi TBS dengan pemupukan NPK didapatkan nilai 0,938 yang berarti terdapat korelasi yang signifikan dengan tingkat koefisien korelasi sangat kuat dan bersifat positif. Hal ini menunjukkan bahwa semakin tinggi pemberian pupuk NPK maka produksi TBS juga semakin meningkat.

Abstract

The increasingly rapid development of technology provides changes in several aspects. Technological advances in this era apart from providing many benefits also provide challenges. One project that can accommodate the zoomer generation in following technological developments is the use of terrarium cultivation. Terrariums fulfill the 3 R principles, namely Reduce, Reuse, Recycle. By planting a terrarium, it means saving water, saving land, and reducing air pollution (Reduce), also reusing unused containers such as used jars (Reuse), and using animal waste as compost (Recycle). The facts in the field are that students as the zoomer generation have received training and socialization on terrarium cultivation, but the level of adoption (acceptance) of students regarding socialization and training on terrarium cultivation varies, therefore a study was carried out to what extent the level of adoption of the results of training and socialization in the application of cultivation terrarium for the zoomer generation. The data collection method used was a survey method with research subjects of the zoomer generation, namely 54 active students. The data collected is categorized tabulatedly and then analyzed descriptively qualitatively. This data analysis uses measurements of observation indicators using a "rating scale". The results of the research show that the level of adoption of zoomer generation innovations in terrarium cultivation, if seen from the latest average, the adoption level is in the very high category. Differences in the level of adoption of terrarium cultivation innovations in the zoomer generation with a very high level of knowledge, a very high level of persuasion/interest, a very high level of decision, a very high level of implementation and a very high level of confirmation. If you look at the overall score, it is in the very high category.

Abstract

Brondolan is an oil palm fruit that is separated from spikelets because it is too ripe during harvesting activities. Apart from that, brondolan is part of the fresh fruit bunch which produces maximum quality Crude Palm Oil (CPO). The aim of this research is to analyze losses from harvesting activities in the form of oil palm fruit stalks. The research method is to carry out quantitative and descriptive analysis. Loss of brondolan fruit during palm oil harvesting activities from the research sample was 10% of the sample block area in the disk area, pickle market area and yield collection area (TPH), amounting to 16,946 Kg/month of the total Kg/division oil palm fruit production. This occurs because the fruit is abandoned or left behind as a result of weak supervision and poor maintenance or maintenance activities in the plate area, pickle market area and TPH area which are not controlled by the growth of weeds, kentosan, this has an impact on the potential loss of 3,2% of total TBS production in the division.
