Penentuan Frekuensi Natural Dan Arah Pergerakan Gelombang (Studi Kasus: Jembatan Soekarno Hatta Kota Malang)

Penelitian ini bertujuan untuk mengetahui nilai frekuensi natural dan arah pergerakan gelombang dari jembatan Soekarno Hatta kota Malang. Perekaman data penelitian menggunakan seismometer portable tipe TDL 303 S (3 komponen) dengan delapan titik pengukuran di sepanjang sisi jembatan. Data hasil perekaman tersebut diolah dengan menggunakan software Geopsy. Analisa data yang digunakan merupakan analisa HVSR dan analisa Particle motion. Analisa HVSR menghasilkan nilai frekuensi dominan dan amplifikasi gelombang. Analisa particle motion menghasilkan plot arah pergerakan gelombang. Berdasarkan analisa data yang dilakukan disimpulkan bahwa nilai frekuensi dominan/frekuensi natural (f0) dari jembatan yaitu berkisar 0,62 sampai 4,34 Hz yang menunjukkan bahwa jembatan sudah tidak layak digunakan sebagai sarana transportasi. Analisa particle motion secara kuantitatif menunjukkan arah pergerakan gelombang ke segala arah baik secara vertikal ataupun secara NS-EWThis study aims to determine natural frequency value of wave and its direction of movement of the bridge Soekarno Hatta town of Malang. Research data using a seismograph recording portable type TDL 303 S (3 components) with an eight-point measurement along the side of the bridge. Its results were processed using the software Geopsy. Analysis of the data used is the HVSR analysis and analysis of Particle motion. HVSR analysis showes values ​​dominant frequency and wave amplification. Analysis of particle motion generates the plot direction of wave propagation. Based on the data analysis it can be concluded that the dominant frequency value/natural frequency (f0) of the bridge is ranged from 0,62 to 4,34 Hz which indicates that the bridge is not feasible to use as a means of transportation. Analysis of particle motion quantitatively indicate direction movement of the waves in all directions either vertically or NS-EW

Effect of Fertilizer on Growth, Yield, and Bean Quality of Four Robusta Coffee Clones Cultivated in Red-Yellow Podzolic Soil Type, North Lampung

Recommendation of Robusta coffee fertilizer that available until now is only in general. In fact, the type and amount of fertilizer needed is highly dependent on environmental conditions, clones, and plant age. The study aimed to investigate the effect of combination doses of urea, SP36, and KCl fertilizer on growth, yield, and bean quality of four Robusta coffee clones cultivated in red-yellow podzolic soil type (PMK), North Lampung. The study was conducted at KP. Cahaya Negeri, North Lampung, with the altitude of 250 m above sea level, PMK soil type and climate type of C (Oldemand), from October 2011 to June 2014. The research was arranged in split plot design with four replications. The main plot was four Robusta coffee clones i.e. (K1) = BP 42; (K2) = BP 409; (K3) = BP 936; and (K4) = BP 939, while the subplot was four combination doses of urea, SP36, and KCl i.e. (P1) = 30:20:20 g/tree; (P2) = 40:30:30 g/tree; (P3) = 50:40:40 g/tree; and (P4) = 60:50:50 g/tree. The results showed that four Robusta coffee clones (BP 42, BP 409, BP 936, and BP 939) cultivated in PMK soil type, KP. Cahaya Negeri, North Lampung, had the same response to combination doses of urea, SP36 and KCl fertilizer. The combination doses of urea, SP36, and KCl of 50, 40, and 40 g/tree, respectively were optimal and efficient for growth and yield of those four clones until 2.5 years old. However, the dose has not yet been able to improve the quality of coffee beans

Rootstock Growth and Green Budding Success of Rubber Plant in Different Sizes of Polybag and Growing Media

Volume and type of growing media is important to support the growth of rubber seedling (Hevea Brasiliensis) for rootstocks. The objective of this study was to determine the growth of rootstock and green budding success of rubber plants in different size of polybag and growing media. The research was carried out since January to December 2013 at the Pakuwon experimental garden, Parungkuda District, Sukabumi Regency, West Java. The study used a randomized block design (RBD) in factorial with two factors and three replications. The first factor is the sizes of polybag: (1) 30 ´ 20 cm, (2) 35 ´ 20 cm, and (3) 40 ´ 20 cm. Meanwhile, the second factor is the growing medium that consists of the mixture of soil and cow manure with 4 proportions: (1) 1 : 0, (2) 3 : 1, (3) 2 : 1, and (4) 1 : 1. Observations were made on the growth of pre-budding rootstock including seedling height, seedling diameter, number of leaves, and the success percentage of green budding. The results showed that the size of polybag has positive effect on the growth of the rubber seedling as rootstock at 6 months old after planting. Moreover, the use of large sizes of polybag (30 x 20–40 x 20 cm) was good for the growth of rootstocks that would be used for green budding. In addition, growing media that consisted of soil and cow manure at a comparison of 1 : 1 gave the highest effect on the growth of rootstock as well as the highest percentage of green budding success. However, there is no interaction between the size of polybag and growing media to the growth of rootstock and green budding success

Steps in Designing Queue and Interview Process Using Information System: a Case of Re-registration of New Students in Universitas Negeri Makassar

. Universitas Negeri Makassar (UNM) have a number of prospective students is quite a lot. Based on data released by the BAPSI UNM (2015) that the data student candidates of UNM who passed the selection with SNMPTN SBMPTN selection as 3,791 people. If the prospective graduate students interviewed are normally it will take a long time and will certainly make students uncomfortable. Therefore it is necessary design an information systems to solving this problem. This research aim to develop an information system to facilitate the process queue. The method used in this research is to use the three stages in the Software Development Life Cycle method namely Initiation Phase, Development/Acquisition Phase, and Implementation Phase. This information system development using PHP and CodeIgniter as a its framework. This design results will be obtained an queues and interviews information system that can be used to manage the queue and interview data. By implementing this system, it potentially reduce time to wait and the process of managing results of interviews can be obtained directly without a process of inputting interview repeat if done manually
