Abstract

Manuverabilitas suatu kapal adalah salah satu kunci untuk menjamin keselamatan jalannya operasional kapal. Kondisi manuver kapal dalam kondisi kapal tidak normal misal mengalami kemiringan akibat bergeseran muatan atau akibat kapal mengalami kebocoran (constant heel) perlu dilakukan antisipasi. Mengetahui karakteristik manuvering kapal dengan kondisi initial constant heel melalui uji model akan memberikan gambaran riil yang terjadi dan menjadi masukan dalam permodelan matematis. Untuk mengetahui pengaruh kemiringan kapal terhadap kinerja manuver kapal maka pada tulisan ini menyajikan hasil pengujian turning dan zig-zag maneuver pada sebuah model kapal patroli pantai dalam kondisi normal dan initial port side constant heel dengan metode free running model. Dari hasil pengujian didapatkan bahwa penurunan dan kenaikan parameter turning maneuverdalam kondisi kapal miring terlihat lebih siknifikan pada transfer dan tactical diameter jika dibandingkan dengan kondisi normal. Saat kapal miring ke kiri (port side initial constant heel) melakukan port side turning, transfer dan tactical diameter model kapal dengan kondisi miring ke kiri mengalami penurunan 2.14% dan 3.03%, sebaliknya saat starboard side turning mengalami peningkatan pada transfer diameter 6.20% dan tactical diameter naik menjadi 8.09% dibandingkan kondisi normal, sedangkan pengaruh initial constant heel pada manuver zig-zag tidak siknifikan

Abstract

ABSTRACTThe impact of soil fertility degradation is the continuous use of inorganic fertilizers, which caused soil organic matter and rice production degradation. The study was conducted to obtain the optimal dose of bioslurry fertilizer for rice growth and production in andosol, regosol, and aluvial soil types without or with soil amendment. The  experiment used split split plot with Completely Randomized Design and three replication. The main plot is soil type, L1:Andosol, L2:mediterranean, and L3:aluvial. The subplots is soil amendment, R1:without amendment, and R2:with amendment. The sub subplots used is bioslurry fertilizer, P1:125kgN/ha, P2:1,5 x 125kgN/ha, and P3: 2 x 125kgN/ha. The results showed that interaction of soil amendment and bioslurry dose had a significant (P<0.05) on the growth and production of Inpari rice. The interaction of soil type and amendment showed significance (P<0.05) in plant height, number of tillers, parameters with highest result at aluvial soil with amendment. The interaction of amendment and bioslurry showed significance (P<0.05) on fresh weight and dry weight of grain parameter with highest result at dose of 2 x 125kgN/ha with amendment. The interaction between soil type, amendment, and bioslurry show significance (P<0.05) at weight of 1000 seeds, and production with ameliorant parameters with highest result in aluvial soil types with 2 x 125kgN/ha dose. Alluvial soil with amendment and bioslurry 2 x 125 kg N/ha dose gave the highest rice production yield of 15,94 t/ha. Keywords: amendment, bioslurry, rice, soil type

Abstract

ABSTRACT The study was aimed to evaluate the effect of spacing of Odot elephant grass (Pennisetum purpureum cv. Mott) and variety of sweet potato (Ipomoea batatas L.) on the growth and yield of these two plants in a mixed cropping system. A randomized block design in a 2 × 4 factorial pattern with 3 replications was used in the study. The first factor was spacing of Odot elephant grass consisted of J1: 60 × 90 cm and J2: 45 x 90 cm. The second factor was several varieties of sweet potato, namely V1: Pating-1, V2: Beta-2, V3: Kidal and V4: Papua Solossa. Parameters observed were plant height, dry matter production, crude protein and crude fiber content of Odot elephant grass, as well as production of tubers, dry matter of leaves, crude protein, crude fiber and brix content of sweet potato. The results showed that there was no significant effect of Odot elephant grass spacing on all parameters studied except plant height on the 5th week of observation. Meanwhile, there was a significant effect on all parameters observed due to the treatment of sweet potato varieties. It was concluded that Odot elephant grass may be mixed with various sweet potato varieties such as Pating-1, Beta-2, Kidal and Papua Solossa, especially if there were no pests attacking the Odot elephant grass at the beginning of its growth. Further research with a more varied spacing of Odot elephant grass spacing is highly recommended.

Abstract

Defense system against interference when the activity is generally done manually by the administrator. This resulted in the integrity of the system depends on the availability and speed of the administrator in response to disturbance. In the current era of information technology, almost all information is important for an institution can be accessed by its users. Disclosure of such access raises new security issues in part of a computer network system that is very important to maintain the validity and integrity of data and ensure availability of services for its users.In this issue then designed a system to detect any interference. The detection is based filtering on the port service, using the programming language Delphi 7. The data obtained from the filtered traffic data packets passing the proxy server. By building a system that can work automatically and in real time, then perform the detection of intruders or illegal activities which will then be reported to the administrator.With this administrator can find out the use of illegal ports through port filter techniques on the traffic data service in and out in real time, from both internal and external networks. Administrators can do the monitoring without having to depend on availability. With such a system administrator can perform tasks more efficiently in maintaining the validity and integrity of data.
