Abstract

Effect of Long Storage entres in Media Store Against Rubber Plant GraftingSuccess Rate (Hevea brasiliensis Muell. Arg) clone PB 260. This study aims to assess theOld Influence Storage entres In Store Media Success Rate Against Plant Grafting Rubber(Hevea brasiliensis) clone PB 260. This research has been conducted in the VillageDistrict of Sembawa Sembawa Banyuasin, with a height of 10 m above sea level. Thisstudy was conducted from September 2014 to November 2014. This study used aRandomized Block Design (RBD), at 4 (four) experimental media store, with longstorage consists of 8 (eight) level and repeated three (3) times. Each experimental unitconsisted of 5 (five) buds and require 480 trial plants. Parameters observation that thepercentage of successful grafting after 30 days (%), shoots mentis (stalk/day), shootheight (cm), number of leaves (strands). The results showed Media store sawdust (M1)show that is capable of storing entres for 1 day resulted in grafting success rate after 30days by 80%, bud stalk mentis 0.19 stalk/day, shoots as high as 18.16 cm high, and thenumber leaves as much as 41 strands. Media store coco (M2) shows that is capable ofstoring entres for 1 day resulted in a success rate of grafting after 30 days at 100%, budstalk mentis 0.29 stalk/day, shoots as high as 13.3 cm high, and the number of leaves of30 strands. Media store banana (M3) indicates that is capable of storing entres for 1 dayresulted in a success rate of grafting after 30 days at 100%, bud stalk mentis 0.37stalk/day, shoots as high as 18.33 cm high, and the number of leaves as much as 49strands. Media store newsprint (M4) show that is capable of storing entres for 1 dayresulted in grafting success rate after 30 days by 70%, bud stalk mentis 0.14 stalk/day,shoots as high as 10.2 cm height and number of leaves as much as 42 strands.Keyword : Long storage, Media store, Entres PB260

Abstract

Abstrak:Asamboratmempunyai gugus sisa asamBO3-3,Jika asamini dipakai dalamesterifikasimaka gugus sisa asamnya akan menggantikan gugus hidroksil yang ada pada etanol. Produkdari esterifikasi ini adalah trietil borat yang dapat digunakan sebagai bahan antiseptik,desinfektan dan antiknock agent(2). Sealain dari penggunaan diatas, etanol dapat diguunakansebagai pelarut dan bahan baku pembuat zat kimia lain. Pada waktu sekarang etanol banyakdiproduksi di Indonesia. Oleh karena itu penggunaannya sebagai bahan baku untuk esterifikasidiharapkan menjadi salah satu upaya untuk penganeka-ragaman pemanfaatan etanol. Objekyang akan diamati adalah “ Pengaruh jumlah katalisator yang digunakan terhadap konversiAsam borat”.Jumlah katalisator yang dimaksud disini adalah banyaknya katalisator yangdigunakan dalamjumlah campuran reaktan yang tertentu dan konstant. Sampai saat ini pengaruhvariabeljumlah katalisator terhadap kenaikan konversi asam borat belum diketahui secarapasti dengan eksperimental. Dalam tulisan ini penulis mencoba mencari berdasarkan studiliteratur text book yang ada dengan sedikit percobaan laboratorium,mencari jumlah katalisatorasam sulfat terhadap konversi asam borat. Pemakaian asamsulfat bervariasi dari 3 ml sampai8ml, dengan temperatur 810 C, asamborat 10 gram, etanol 300ml, kecepatan pengadukan 400rpmdan waktu 60menit.Selain jumlah katalisator, variabel lain adalah temperatur,waktu , jenis katalisator dan kecepatanpengadukan. Dalam hal ini ke 4 variabel tersebut bukan merupakan variabel utama sehingganilai dianggap konstant. Jumlah katalisator asamsulfat akanmempoengaruhi kenaikan konversiasamborat secara liner. Penulis bertujuanmengamati untukmengetahui gejala yang ditimbulkanoleh pemakaian jumlah katalisator asamsulfat terhadap konversi asam borat pada esterifikasietanol dengan asam borat.KataKunci: Etanol, Esterifikasi

Abstract

This study aims to observe the effect of various types of mulch on the growth and yield of seedless watermelon (Citrullus vulgaris Schard). Implementing research in farmers' fields Scales Village, District Indralaya, Ogan Ilir, with a height ranging from 4-22 m above sea level, from February to April 2012. Research design using randomized block design, consisting of five treatments and five replications. The treatments were P0 = control (without mulch), P1 = use black-silver plastic mulch, P2 = use black plastic mulch, mulch P3 = using reeds as mulch as 0.8 kg of dry weight per m², P4 = use corn stalks mulch 2.6 kg dry weight per m². Parameters observed that the length of plant, days to flowering, fruit diameter, mean fruit weight, fruit weight per plant, fruit weight ha-1 (yield), wet biomass, and weight of wet roots. Black-silver plastic mulch influenced better on the growth and yield of seedless watermelon, compared with the other mulch and can increase the production of fruit namely the fruit weight/plant of 10.15 kg or 20.3 tons ha-1.

Abstract

This research aimed to assess the effect of alternative plant growth regulators to the growth of stum dorman see rubber Klon BPM 24. This research was done at Lubung Saung Village, District And Banyuasin III Regency South Sumatera Province. This research used a randomized block design with five treatment and five replications. The treatments studied were B0 = 0 ml L-1control, B1 = 2 ml L-1 of water, B3 = 6 ml L-1of water, B4 = 8 ml L-1 of water. Each treatment consisted of 10 plants, with a long soaking the whole treatment is 15 minutes. Thus obtained 25 combined treatment. Each unit experiments are 3 examples of plans. Parameters namely speed sprout observations (HST), shoot length (cm), number of leak stalk (strands), the percentage of seedlings grown (%), weight berangkasan wet plant (g), dry weight of berangkasan plant (g), weight of wet roots departure (g), dan root dry weight berangkasan (g). Based on result obtained it can ce concluded that, the concentration of growth regulators treatment 0f 8 ml L-1 water tends to give the highest yield and better seed to grow that percentage to 80 %, the speed of growth is 20.40 HST shoots, shoot length is 30.79 cm, weight is plants dry berangkasan 7.10 g, wet weight is 1.94 g root, root dry weight is 0.88 g.
