Authors: AMALIANA LUTHFATUL , DEWI MADE LARAS SETYANA
Published: February 2022

Small Area Estimation (SAE) is a statistical technique for estimating the parameters of a sub-population with a small sample size. SAE aims to improve the accuracy of parameter estimation, with indirect estimation. This study aims to determine the best method between empirical best linear unbiased prediction (EBLUP) and spatial EBLUP methods (with a queen contiguity weighted matrix) in estimating per capita expenditure per sub-district in Bali. The results of this study indicate that the best SAE method in estimating per capita expenditure per sub-district in Bali is the EBLUP method with the smaller mean squared error. The EBLUP estimation results are significantly influenced by three variables, namely the population, public primary schools, and families using PLN. The sub-district with the highest per capita expenditure in Bali is Denpasar Selatan sub-district. Meanwhile, the sub-district with the lowest per capita expenditure was Abang sub-district. Since the EBLUP model is better than SEBLUP model, this indicates that per capita expenditure per sub-district in Bali is not influenced by its neighbors.

Kajian Numerik Perilaku Seismik Link Geser Pada Sistem Struktur Baja Tahan Gempa Tipe EBF
Authors: Yurisman Yurisman , Army Buyung , Sari Desnila , Chairi Maiyozzi
Published: February 2022

Artikel ini memaparkan hasil studi numerik terhadap perilaku link geser (shear link) pada sistem struktur baja tahan gempa tipe Eccentrically Braced Frame (EBF). Rangka baja berpengaku eksentrik (EBF) mempunyai kekakuan elastik yang sangat baik dibawah pembebanan lateral sedang dan mempunyai daktilitas yang tinggi saat dibebani beban gempa yang besar. Dibawah kondisi pembebanan ekstrim perilaku inelastik direncanakan untuk ditahan oleh Link. Kinerja dari system struktur EBF sangat tergantung dari perilaku elemen link yang berfungsi sebagai sekring pada sistem struktur tersebut. Dalam kajian ini telah diteliti terhadap beberapa parameter yang berpengaruh secara signifikan terhadap perilaku seismik elemen Link. Kajian ini bertujuan untuk mendapatkan Link dengan kinerja seismic (kekuatan, kekakuan, daktilitas dan dissipasi energi) yang lebih tinggi dibandingkan dengan link standar AISC sehingga diharapkan  pada akhirnya akan mendapatkan sstem EBF dengan kinerja yang lebih baik. Kinerja Link diukur dalam nilai kekuatan (strength), kekakuan (stiffness), daktilitas (ductility) serta kemampuan Link dalam melakukan dissipasi energi. Kajian dilakukan secara numerik dengan menggunakan program applikasi Patran_Nastran   dimana Link dimodelkan sebagai balok yang terpisah dari system EBF (sub assembly) yang dikekang pada kedua ujungnya sementara pada salah satu ujung tersebut diberikan beban perpindahan secara siklik dan monotonik dengan kontrol perpindahan (displacement control). Beberapa parameter yang diteliti mencakup parameter penampang, modifikasi terhadap pengaku dibagian badan. Parameter penampang yang diteliti adalah yang terkait dengan kelansingan penampang (h/tw, bf/tf) sedangkan modifikasi terhadap pengaku badan dilakukan dalam bentuk pemasangan pengaku dalam arah diagonal. Hasil penelitian menunjukkan bahwa parameter kelansingan badan (h/tw) , kelansingan sayap (bf/2tf), dan penempatan pengaku secara diagonal mempunyai pengaruh yang signifikan terhadap kinerja Link, sedangkan jarak plat pengaku lateral tidak mempunyai pengaruh yang berarti. Hasil analisis terhadap perilaku seismik Link geser dinyatakan dalam bentuk kurva beban vs perpindahan. Dari hasil kajian ini dapat disimpulkan bahwa untuk mendapatkan Link dengan kinerja yang lebih baik dapat dilakukan dengan cara modifikasi terhadap penampang dan melakukan rekayasa terhadap geometrik pengaku badan (pengaku vertikal dan diagonal).

Ketersediaan kelapa sawit rata-rata 2 juta ton per tahun di Provinsi Riau selain meningkatkan perekonomian juga dapat menimbulkan permasalahan di kalangan industri sebagai penghasil limbah sawit. Salah satu pemanfaatan limbah sawit adalah menggunakan abu sawit sebagai material campuran untuk pembuatan campuran mortar untuk pembuatan bata ringan Cellular Lightweight Concrete (CLC). Penelitian ini bertujuan untuk menentukan nilai kuat tekan maksimum berdasarkan persentase substitusi POFA (Palm Oil Fuel Ash) dalam campuran mortar CLC. Persentase campuran POFA yang digunakan adalah 5%, 10%,15% dan 20% dari berat semen dalam campuran mortar CLC. Penelitian dilakukan secara eksperimental di laboratorium untuk mendapatkan kuat tekan mortar dengan ukuran sampel mortar kubus dengan sisi 10 cm3. Hasil penelitian mortar menunjukkan bahwa kuat tekan optimum pada umur 28 hari berada pada komposisi 10% POFA dengan kuat tekan maksimum 1,41 MPa. Berdasarkan hasil pengujian kekuatan mortal CLC dapat disimpulkan bahwa penambahan persentase POFA (Palm Oil Fuel Ash) 10% dari kadar berat semen dapat meningkatkan nilai kuat tekan pada campuran mortar bata ringan sebesar 34,3 % dibandingkan tanpa menggunakan POFA.
Penentuan Tingkat Akurasi Beberapa Metode Prediksi Efisiensi Tangkapan (Trap Efficiency) Sedimen di Waduk Mrica
Authors: Utomo Puji , Febriani Prisca
Published: February 2022

Sedimentasi waduk merupakan permasalahan global yang sangat penting dalam perencanaan waduk karena menyebabkan penurunan kapasitas tampungan waduk. Dalam menghitung sedimentasi waduk, biasanya meliputi sedimen yang masuk, sedimen yang keluar, dan endapan sedimen di dalam waduk, sehingga didapatkan imbangan sedimen yang terjadi. Namun dalam praktik di lapangan, tidak semua melakukan ketiga perhitungan tersebut, karena pertimbangan biaya pelaksanaan yang cukup mahal. Untuk mengatasi hal tersebut, perhitungan sedimentasi dilakukan dengan pendekatan konsep efisiensi tangkapan (trap efficiency) sedimen. Selama ini pendekatan konsep ini didasarkan pada hasil penelitian di luar negeri dan tingkat akurasi masih belum optimal. Tujuan penelitian ini untuk mengetahui tingkat akurasi dari beberapa metode prediksi efisiensi tangkapan sedimen. Penelitian ini dilakukan di Waduk Mrica, Kabupaten Banjarnegara. Data-data yang diperlukan berupa data sekunder, seperti: data debit inflow, data rating curve debit sedimen, data pengukuran echosounding, data analisa butiran sedimen dasar waduk, dan data teknis waduk. Tahapan yang dilakukan dalam penelitian ini, diantaranya: menghitung sedimen yang masuk, sedimen yang mengendap, efisiensi tangkapan, dan mendapatkan tingkat akurasi dari beberapa metode yang ditinjau. Kriteria statistik dari metode terpilih harus memiliki nilai korelasi > 0,6 dan error < 20%. Imbangan sedimen di Waduk Mrica menunjukkan bahwa laju sedimen yang masuk sebesar 6,001 juta m3/tahun. Sedimen rerata yang mengendap sebesar 3,850 juta m3/tahun, sehingga sedimen yang dikeluarkan rerata sebesar 2,151 juta m3/tahun. Tingkat akurasi dari metode prediksi efisiensi tangkapan bervariasi dari sedang sampai kuat. Metode prediksi efisiensi tangkapan sedimen Brune, Harbor dkk, dan Jotihiprakash dan Garg dianggap paling representatif untuk digunakan pada Waduk Mrica.

The existence of Pantura road as a physical facility is to support the daily needs of the people surrounding the Pantura Eretan Kulon Road. However, the operation of the Cikopo-Palimanan (Cipali) toll road in June 2015 caused the movement switch from Pantura Road to the Cipali toll road given a change in economic activity and land use in Pantura Eretan Road Corridor. The purposes of this study are to identify changes in economic activities and land use after the operation of the Cipali toll road by comparing the economic activities and land changes in the year of 2014 and 2019. Spatial analysis method and descriptive statistical analysis method were used in this study. The results of the analysis show that the operation of the Cipali toll road have led to a decrease in the number of business activities, especially the food business, a decreased income in the Pantura Road Corridor which is still below the Regency Minimum Wage (UMK) Indramayu and based on BPS is still low, changes conversion of the widest land use function in trade and services to become yard land which has no economic value, and a decrease in land use based on the function of buildings in the corridor of Jalan Pantura which is dominated by restaurants. On the other hand, the operation of the Cipali toll road results in a decrease of traffic volume on Jalan Pantura due to the reduced traffic generation so that the traffic congestion is reduced.
