Abstract

The potential of high-quality wood for various purposes over the past decade is very difficult to obtain. This is due to the high rate of doforestation and forest degradation, especially in Riau Province. Examples of the use of high-quality wood, especially in Riau Province, is as material for creating 'pathways' in the context of preserving track culture in the Kuantan Singingi Regency. The purpose of this study is to determine the physical properties of red balam wood and bintangur that grow in Riau before and after the preservation process, and determine the strength class of red balam wood and bintangur that grows in Riau. The research was carried out on the starur trees and red balam with a diameter of 34-38 cm, tree height 18-22 m. The tree sample comes from the Rumbio customary forest and the Minas Tahura KPHP Riau Province. Examination of physical properties using British standards in 1957. The results showed that based on specific gravity, the red balam wood and bintangur before preserved and included as strong class II. The average moisture content of each wood is 14-30%. The largest wood shrinkage development in each wood occurs at the base of the wood.

Abstract

This research objectives are to find out the appropriate tapping time and its effect on the latex production of PB 260 rubber plantation so that the highest production would be gained.      The experiment was carried out in the Bukit Selanjut Village, Kelayang Districts, Indragiri Hulu Regency, Riau Province. The study was conducted for 1 month from September to October 2016. The study arranged experimentally using Completely Randomized Block Design with  7 treatments and 3 replications then obtained 21 experimental units.               The treatment of rubber plantation tapping time used is K1: 05.00 am, K2: 05.30 am, K3: 06.00 am, K4: 06.30 am, K5: 07.00 am, K6: 07.30 am and the K7: 08.00 am. The parameters were observed drip duration of latex droplet, latex volume and dry rubber content. Data was analyzed statistically using ANOVA and tested by Duncan’s New Multiple Range Test (DNMRT) at 5% level. The research result showed that different tapping time effect the parameters drip duration of latex, latex volume and the dry rubber content. Tapping the rubber plant at 06.00 am was the best time for tapping because it creates the longest latex droplet which was 78,38 minutes, highest latex volume was 81,73 ml and highest dry rubber content was  68,26%. Keywords: Hevea brasiliensis Muell Arg, PB 260 clone, tapping time

Abstract

Water availability is a major factor limiting the production rate of oil palm plantations. Availability of water for palm oil plants in the field is obtained from rainfall. The research was conducted at PT. Perkebunan Nusantara V Tandun Estate, Riau Province, for three months starting in June until August 2016. This study uses secondary data available on the administration of the garden. Secondary data for analysis include TBS monthly production data for 5 years (2011-2015), the data age of the plant 5, 10 and 20 years after planting, rainfall data and rainy day for 9 years (2007-2009). The analytical method used is analasis multiple linear regression and correlation models tested for feasibility with the classical assumption test including normality test, heteroscedasticity test and multicollinearity test. Regression analysis showed that variable rainfall and rainy days significantly affected on alpha 1% (Sig <α 0,01) to FFB production at the age of 5 years. Results F-count of 29.07 with a significance value of 0.00. The coefficient of determination (R2) obtained 63.8%. This means that 63.8% of FFB production variations can be explained by the variation of the variables used and the remaining 36,2% is explained by the other variables not incorporated into the model. Regression analysis equation on a 5-year-old plant was Y = 414633.827 + 2530.523 X1 - X2 21848,726. Results of correlation analysis at 5 years old plants showed variable rainfall and rainy days have a very strong relationship. Correlation value of rainfall and rainy days and 0.720 - 0.543.Keywords: rainfall, raining, FFB production.

Abstract

Tujuan penelitian ini adalah merancang dan membangun komunikasi suara melalui jaringan IP menggunakan sistem operasi Briker. Penggunaan VoIP Server untuk melakukan panggilan dari VoIP client ke sesama VoIP client, dan dari nomor VoIP rakyat menuju salah satu VoIP client, dan juga mencari perbandingan delay suara client IP publik dan IP local di Dishubkomintel Aceh. Metode penelitian yang dilakukan terdiri dari beberapa tahapan yaitu; 1) Desain Sistem, 2) Topologi Jaringan, 3) Perancangan pada Sisi Server, 4) Perancangan pada Sisi Client, 5) Instalasi Sistem Operasi dan Aplikasi, 6) Konfigurasi, 7) Pengujian Konektivitas Jaringan VoIP, dan 8) Pengamatan Kerja VoIP. Dari hasil pengujian, maka dapat diambil beberapa kesimpulan yaitu; 1) VoIP Server Briker berperan menangani panggilan SIP dari seluruh client yang teregister ke dalam Server Briker, 2) Antara VoIP client dapat saling berkomunikasi dua arah ketika sudah teregister ke dalam Server Briker, 3) Panggilan menuju voip rakyat dilakukan dengan menekan ?9? yang digunakan sebagai Outbound routes kemudian dilanjutkan dengan menekan nomor yang dituju, dan 4) Panggilan dari voip rakyat menuju VoIP dilakukan dengan menekan nomor telepon VoIP rakyat yang dihubungkan dengan VoIP Server kemudian akan diterima oleh IVR (Interface Voice Response) yang akan diarahkan menuju nomor extension yang dituju.Kata Kunci:Komunikasi Suara, Jaringan IP, VoIP, Briker

Abstract

Demands on peanuts in Riau Province increasing every year while the production decreases, resulting in the unfulfilled demands on peanuts. Efforts that need to be done to overcome this obstacles are finding the suitable planting space to plant talam-1 varieties and giving arbuscular mycorrizhal fungi (AMF) to help absorb the plant nutrients. The research aims are to find out the effect of planting space and arbuscular mycorrhizal fungi distribution to growth and production of peanuts (Arachis hypogaea L.) talam-1 varieties and to find the best treatment. This research is factorial experiment which is arranged based on RAL with two factors. Factor I is planting space with two levels J1:40cm x 20cm and J2: 40cm x 40cm. Factor II is the dosage of arbuscular mycorrhizal fungi with four levels H0:withoutAMF,  H1: AMF 5g per plant, H2: AMF 10g per plant and H3: AMF15g per plant.The result shows that planting space management and arbuscular mycorrhizal fungi distribution are yet able to increasethe peanut’s growth and production on all parameters, exceptthe hight parameter of peanuts (Arachis hypogaea L). Keyword(s): peanut, plant space, arbuscular mycorrhizal fungi,production.

Abstract

Black soybean production in Indonesia has not been able to meet national consumption. This problem can be overcome by applying liquid organic fertilizer and adjusting the spacing. This study aims to determine the effect of various spacings and concentrations of liquid organic fertilizer on the growth and production of black soybeans. This research was conducted from June to September 2019 using a completely randomized design with three replications. The first factor is the spacing between two levels, namely J1 = Planting distance (40 x 15)cm, J2 = (40 x 20)cm. The second factor is the concentration of liquid organic fertilizer (POC) consisting of 4 levels, namely: K0 = no liquid organic fertilizer + 50 kg.ha-1 Urea, 70 kg.ha-1 TSP, 100 kg.ha-1 KCl, K1= concentration 0.4% + 25 kg.ha-1 Urea, 35 kg.ha-1TSP, 50 kg.ha-1 KCl, K2 = 0.6% concentration + 25 kg.ha-1 Urea, 35 kg.ha-1TSP, 50 kg.ha-1 KCl, K3 = 0.8% concentration + 25 kg.ha-1 Urea, 35 kg.ha-1TSP, 50 kg.ha-1 KCl. Parameters observed consisted of chlorophyll content, flowering plant age, plant height, number of primary branches, harvest age, total number of pods per plant, number of pithy pods, percentage of pithy pods, number of seeds per plant, dry seed weight per plot, dry seed weight. per plant, weight of 100 seeds and harvest index. The results showed that plant spacing had a significant effect on the number of primary branches, the total number of pods per plant, the number of pithy pods, and the number of seeds per plant. The concentration of liquid organic fertilizer has a significant effect on the chlorophyll content. Interaction of plant spacing concentration of liquid organic fertilizer had a significantly affected chlorophyll content and harvest index. Keywords: Plant spacing, black soybean, liquid organic fertilize
