Abstract

Jaringan jalan mempunyai peranan dalam melancarkan angkutan barang maupun manusia dari suatu daerah ke daerah yang lain. Jalan merupakan prasarana transportasi darat, jika prasarana transpotasi  dalam kondisi baik maka transportasi juga akan berjalan baik, dampaknya bermacam-macam antara lain pengendara merasa nyaman, kecelakaan berkurang, lalu lintas berjalan lancar, perekonomian meningkat. Kondisi perkerasan jalan akan dipengaruhi oleh jumlah dan jenis kendaraan yang lewat, kualitas bahan material, perawatan, kualitas drainase dsb. Dalam studi ini akan dibahas tentang perkerasan exsisting masih mampu menahan beban LHR (Lalu Lintas Harian Rata-rata) yang ada  dengan metode membandingkan  ITP exsisting dengan ITP berdasarkan data lalu lintas yang ada. Dari hasil analisis dapat disimpulkan bahwa pada IndekTebalPerkerasan (ITP exsisting) Jl. Dr. Cipto, Jl.S.Parman dan Jl. Sugiyopranoto diperoleh berturut-turut 11,25 ; 11,2 ; 11,16 dan  ITP berdasarkan data lalu lintas yang ada berturut-turut sebesar 11,0 ; 10,0 ; 10,5. Sehingga dapat diambil kesimpulan tebal perkerasan dari ketiga jalan raya (Jl. Dr. Cipto, Jl. S. Parman dan Jl. Sugiyopranoto) tahun 2014 masih mampu menahan beban lalu lintas yang ada. Kesimpulan dari studi kasus ini berdasarkan analisis dari data lalu lintas th 2013 maka ketiga jalan tersebut pada tahun 2014 belum perlu dilakukan Overlay atau penambahan tebal perkerasan.

Abstract

The connectivity between Kendari City and Konawe Kepulauan Regency has affected the development of both regions. The connectivity between those two regions consists only of sea transportation with two types of transportation mode. The purpose of this study is to observe the behavior of users of sea transportation mode and to analyze characteristics of users of wooden ships and ferries on the Kendari City - Konawe Kepulauan Regency route, based on the preferences of passengers on the variety of attraction of the two modes. In this study, the characteristic of the selection of the sea transportation modes influences the total of traffic in the connection of both regions. The research design of this study is a modeling approach using a binomial logit model and a sample of 90 respondents. The results show that travel cost accounts for the difference in model utility which influences  the selection of sea transportation modes for the two regions. Based on the perception of users, for ferries the purpose of trip is mostly for work while for wooden ships the purpose is mostly social. The reasons for selecting wooden ships are a variety of time and trip frequency, whereas the reason for selecting ferries is the cost.

Abstract

In order to be an effective management of irrigation water, the flow rate should be measured in the upstream primary channels, the branch line and the tapping tertiary buildings. However, to simplify the management of irrigation network have only a few building types that may be used in irrigation areas. This study is limited to measure rate of flow through the spillway sillwidth with a round shape and spillway sill lighthouse thin rectangular. The methodology used was tested in the laboratory by varying the flow hydraulics start of Q1, Q2, Q3, ..., Qn, to get the water level variations in the upstream and the downstream in spillway is constan, which can be obstained with the relationship between the discharge water level in the upstream and downstream of the spillway. Besides, it was also found the relationship of the variation of the discharge flowed through the sill wide spillway and thin threshold to high energy lost occurs. From the results of this research, the relationship with the discharge water level in the upstream, downstream water level, water level above the threshold, and the threshold energy loss for the overflow width spillway and thin sill have a similar trend. To spillway width threshold produces less energy loss than the spillway sill thin with trend Y = - 405,6 X2 ? 11,99 X ? 0,001 for sill width spillway and Y = 1,183 X 0,552 for the overflow thin threshold with Y is the loss energy in meters and X in discharge in m3/s.

Abstract

(Anacardium occidentale L.) is a conservation plant and its development in Indonesia has been started since 1975 through the Ministry of Forestry's project as a conservation plant to repair critical land. The study was conducted for three months, starting from March to May 2018. The research location was located in the nursery around the Forestry Science Laboratory of the Faculty of Forestry. This study uses a factorial Randomized Complete Design Method (RAL) consisting of two factors, namely the first factor of light intensity C1 = 30%, C2 = 50%, C3 = 70% and C4 = 100% and the second factor is the dose of Urea P0 = without Urea fertilizer, P1 = 1 g and P2 = 2 g per polybag. The combination of the two factors is 12 combinations and each treatment is repeated 4 times. The parameters observed included height increase, increase in diamater, increase in number of leaves and measurement of leaf area. The results of this study indicate that the treatment of Urea fertilizer dosage has a very significant effect on the increase in cashew nut seedlings aged 12 MST. The treatment of 2 g fertilizer dose gave a high increase of 2.0 cm which was significantly different from the treatment without fertilizer (P0) which was 1.4 cm. In addition, the treatment of light intensity and its interaction with Urea fertilizer has no significant effect on all observational parameters of age 12 MST. The treatment of 30% light intensity gave the best results for height increments of 2.0 cm and an increase in diameter of 0.82 mm at 12 MST. The interaction of light intensity and urea fertilizer (C1P2) tended to give the best effect on the parameters of high increase of 2.5 cm, the increase in diameter of 0.82 mm and the increase in the number of leaves of 2.4 strands aged 12 MST.Keywords: Light Intensity, Cashew Seed Urea Fertilizer (Anacardium Occidentale L).

Abstract

Aktifitas PKL dan kendaraan yang melakukan parkir pada badan jalan menimbulkan kemacetan lalu lintas dan berkurangnya tingkat pelayanan jalan. Tujuan dalam penelitian ini adalah mengidentifikasi dan menganalisis pengaruh keberadaan PKL dan parkir terhadap kinerja jalan. Metode penelitian yang digunakan adalah metode penelitian survey yang dilengkapi dengan observasi. Penelitian ini menggunakan data kuantitatif yang dianalisis dengan kualitatif deskriptif. Berdasarkan hasil penelitian, disimpulkan bahwa pada ruas jalan arteri, PKL dan parkir memiliki pengaruh yang signifikansebesar 0,026 terhadap DS dan 0,028 terhadap kecepatan, dengan kenaikan DS sebesar 14%, dan penurunan kecepatan sebesar 26%, hal tersebut juga terjadi karena pada lokasi penelitian terdapat U-Turn, lokasi tersebut merupakan jalan arteri 2 arah yang dipisah oleh median, serta perbedaan fungsi guna lahan. Sedangkan pada ruas jalan kolektor, keberadaan PKL dan parkir mempengaruhi DS sebesar 0,049 dengan kenaikan DS sebesar 7%. Sedangkan terhadap kecepatan pengaruhnya tidak signifikan sebesar 0,064, tapi terjadi penurunan kecepatan sebesar 7%. Pada ruas jalan lokal, keberadaan PKL dan parkir tidak berpengaruh signifikan baik terhadap DS maupun kecepatan, namun terjadi peningkatan DS sebesar 80%, dan penurunan kecepatan sebesar 10%,selain PKL dan parkir, hal tersebut juga disebabkan oleh volume lalu lintas yang secara langsung mempengaruhi hambatan dan kinerja jalan
