Perangkat lunak AB Pro merupakan produk dari PT XYZ. Perusahaan mengharapkan produk ini bebas dari failure kategori major, critical dan blocker yang tidak dapat diselesaikan pada level support call. Semua jenis failure ini menyebabkan operasi bisnis pelanggan terganggu. Failure terjadi karena kurang maksimalnya proses pengujian. Untuk mengetahui kualitas proses pengujian yang sedang berlangsung dibutuhkan asesmen tingkat kematangan proses pengujian tersebut. Maka dari itu, tujuan penelitian ini adalah untuk mengetahui tingkat kematangan proses pengujian dan memberikan rekomendasi perbaikan proses pengujian perangkat lunak AB Pro. Model yang digunakan untuk mengevaluasi kematangan proses pengujian pada penelitian ini adalah Test Maturity Model Integration (TMMi). Model ini memenuhi kebutuhan perusahaan, terutama tahapan yang jelas untuk menentukan arahan komitmen manajemen. Metode penilaian mengacu pada TMMi Assessment Method Accreditation Requirements (TAMAR). Penelitian dilakukan secara kualitatif dengan metode reduksi. Pengambilan data dilakukan dengan FGD bersama dua orang ketua tim pengujian, observasi proses, dan studi dokumen pendukung. Hasil penelitian menunjukkan bahwa tingkat kematangan proses pengujian perangkat lunak di PT XYZ berada pada tingkat kematangan 1 initial. Hal ini menunjukkan bahwa proses pengujian belum dikelola dengan baik dan terdapat pelaksanaan proses yang tidak konsisten. Penelitian ini merekomendasikan perusahaan melakukan enam perbaikan proses pengujian. Tiga rekomendasi jangka pendek (1-6 bulan), yaitu: melakukan monitor kualitas produk; menggunakan teknik desain pengujian; mengembangkan prosedur proses pengujian. Tiga rekomendasi jangka menengah (7-12 bulan), yaitu: membentuk seperangkat indikator kinerja proses pengujian; menentukan estimasi proses pengujian; menjaga serta mendistribusikan komitmen untuk pengujian. ......Software AB Pro is a product of PT XYZ. The company expects this product to be free from major, critical and blocker failure that cannot be resolved at support call level. All these failures disrupt the customer’s business operations. Failures occur when the testing process is unoptimized. To analyze current testing process quality, testing process maturity level assessment is required. Thus, this study aimed to determine testing process maturity level and provide recommendations to improve AB Pro testing process. The assessment model used in this study is Test Maturity Model Integration (TMMi). The chosen model meets the company requirements, especially having clear steps to determine the direction of management commitment. The assessment method refers to the TMMi Assessment Method Accreditation Requirements (TAMAR). The research was conducted qualitatively with the reduction method. Data collection was carried out through FGD with two team leaders, process observation, and study of supporting documents. From the result, software testing process maturity is still at initial level. This result indicates the testing process has not been appropriately managed, and there is inconsistency of process implementation. There are six recommendations for PT XYZ to improve their testing process. Three short-term recommendations (1-6 months): monitor product quality; use test design techniques; develop process testing procedures. Three medium-term recommendations (7-12 months): establish a set of performance indicators of the testing process; determine the estimation of the testing process; maintain and distribute commitments for testing.

Catamaran resistance is very complex compared to monohull resistance, so it is particularly worthy of research. The below-water-level hull form influences the fluid flow characteristics around the ship, which either increases or decreases the total resistance. This study focuses on developing a new hull form by using the Lackenby Method to modify an existing hull form in such a way that reduces the total resistance. The total resistance was calculated using computational fluid dynamics, since the Navier-Stokes equation is built into the Tdyn software. The research results show that hull form changes can in fact decrease or increase the ship?s total resistance. The best new hull form was chosen for its value of least total resistance.

Resistance or drag is one of the most important factors in ship design, in particular in connection with the development of more efficient and environmentally friendly vessels. The shape of the hull under water will affect the fluid flow characteristics around the ship, hence causing the resistance to increase or decrease. If the resistance increases, the size of main engine and subsequently, the fuel consumption increases accordingly and this is not often anticipated by ship designers and operators. The use of a catamaran for passenger carriers is well known and its application for fishing vessels has received serious attention in the last few years, due to its advantages to produce wider deck area and smaller size of engine at the same displacement as the monohulls. The conversion of monohull fishing vessels in Cilacap the waters into a catamaran hull is an interesting topic in association with the development of better fishing vessels in this region. The resistance investigation of the conversion vessel was carried out by Computational Fluid Dynamics (CFD) approach and this is combined with classical slender body theory. In terms of mathematical calculation, the results between CFD and the combination of empirical formulas and slender body theory shows such a good agreement and the difference between the two is less than 5%. In terms of naval architecture, the results showed that the modification of a monohull vessel into a catamaran can increase the payload capacity up to two times. Conversely, this causes the resistance to increase about almost four times and this is certainly unpopular for the fishermen.

Transportasi udara yang mampu beroperasi di landasan pacu pendek merupakan kebutuhan bagi negara kepulauan seperti Indonesia. Salah satu desain yang berhasil memenuhi kebutuhan ini adalah pesawat PT Dirgantara Indonesia (PTDI) N219 yang dapat dikembangkan sebagai pesawat amfibi. Ponton apung di atas pesawat amfibi memiliki bentuk lambung tipe katamaran. Pengembangan desain pada float dapat dilihat reduksi hambatannya. Salah satu upaya yang sering dilakukan dalam rekayasa desain adalah biomimikri. Jenis rekayasa ini merupakan proses untuk membuat desain yang berkelanjutan dengan meniru bentuk, mekanisme, atau evolusi berbagai hewan ke ekosistem yang ditempatinya. Ikan layar (Istiophorus platypterus) memiliki dimensi tubuh yang mampu mereduksi hambatan secara signifikan. Tujuan dari penelitian ini adalah membuat desain lambung katamaran sebagai ponton apung pada pesawat N219 dengan mengadaptasi karakteristik hidrodinamik ikan layar. Tiga desain catamaran dirancang dalam penelitian ini: (1) ponton apung kontrol menggunakan desain komersial WIPLINE®️ 13000 sebagai desain kontrol 1, (2) model katamaran berbadan ikan layar sebagai desain kontrol 2, dan (3) desain awal ponton apung dengan adaptasi ikan layar sebagai desain uji. Pengujian dilakukan secara numerik dengan simulasi CFD (Computational Fluid Dynamics) menggunakan ANSYS FLUENT untuk menentukan nilai hambatan, koefisien hambatan (Ct) dan visualisasi aliran karakteristik hidrodinamika masing-masing desain lambung. Pada desain kontrol 1, nilai hambatan minimal sebesar 11603,00 N (Fn = 0,40) dan maksimal sebesar 24267,00 N (Fn = 0,70), lebih tinggi jika dibandingkan dengan desain uji yang memiliki nilai hambatan minimal sebesar 2126,54 N (Fn = 0,40) dan maksimal sebesar 4452,88 N (Fn = 0,70). Pada desain kontrol 1 nilai koefisien hambatan dengan nilai minimal sebesar 11,06 (Fn = 0,70) dan maksimal sebesar 18,19 (Fn = 0,45), lebih tinggi jika dibandingkan dengan desain uji yang memiliki nilai koefisien hambatan minimal sebesar 4,34 (Fn = 0,70) dan maksimal sebesar 7,01 (Fn = 0,45). Berdasarkan hasil tersebut dapat dikatakan bahwa upaya biomimikri dengan mengadaptasi karakteristik hidrodinamik ikan layar pada desain ponton apung katamaran berhasil menurunkan nilai hambatan secara signifikan ......Air transportation capable of operating on a short runway is a necessity for an archipelago such as Indonesia. One of the designs that succeeded in meeting this need was PT Dirgantara Indonesia's (PTDI) N219 aircraft which can be developed as amphibian aircraft. Float on seaplanes has a catamaran-type hull shape. Design development on a float can be seen from drag reduction. One of the efforts that is often done in design engineering is biomimicry. This type of engineering is a process to create sustainable designs by mimicking the shape, mechanism, or evolution of various animals to the ecosystem they occupy. Sailfish (Istiophorus platypterus) have body dimensions that can reduce barriers significantly. The objective of this research is to create a catamaran hull design as a float on N219 aircraft by adapting the hydrodynamic characteristics of sailfish. Three catamaran designs were designed in this study: (1) float using commercial WIPLINE®️ 13000 design as control design 1, (2) sailfish-bodied catamaran model as control design 2, and (3) initial design of the test float with the adaptation of sailfish test design. Tests are performed numerically with a CFD (Computational Fluid Dynamics) simulation using ANSYS FLUENT to determine resistance, drag coefficient (Ct), and flow visualization of each hull designs' hydrodynamic characteristics. In control design 1, the minimum resistance value is 11603.00 N (Fn = 0.40), and the maximum is 24267.00 N (Fn = 0.70), higher than the test design which has a minimum resistance value of 2126. 54 N (Fn = 0.40) and a maximum of 4452.88 N (Fn = 0.70). In control design 1 the value of the resistance coefficient with a minimum value of 11.06 (Fn = 0.70) and a maximum of 18.19 (Fn = 0.45), is higher than the test design which has a minimum drag coefficient value of 4, 34 (Fn = 0.70) and a maximum of 7.01 (Fn = 0.45). Based on these results, it can be said that the biomimicry effort by adapting the hydrodynamic characteristics of sailfish to the catamaran floating pontoon design has succeeded in reducing the resistance value significantly

Indonesia merupakan negara dengan gugusan pulau terbanyak di dunia dengan lebih dari 17.000 pulau. Hal tersebut menjadi tantangan tersendiri bagi pemerintah dalam pemerataan fasilitas pelayanan kesehatan di tiap daerah Indonesia. Berdasarkan data dari Perhimpunan Rumah Sakit Seluruh Indonesia (PERSI) tahun 2020 terdapat 2.924 unit rumah sakit yang terdiri dari 60 rumah sakit kelas A, 430 rumah sakit kelas B, 1.524 rumah sakit kelas C, 42 rumah sakit kelas D pratama, dan 52 rumah sakit lainnya yang belum dikategorikan. Persebaran rumah sakit di Indonesia masih belum merata. Hal tersebut dibuktikan dengan data peta persebaran rumah sakit yang masih terpusat di pulau Jawa dan sebagian pulau Sumatera sedangkan daerah bagian timur Indonesia masih sangat minim fasilitas rumah sakit. Salah satu fasilitas pelayanan kesehatan yang cocok dengan kondisi geografis Indonesia yaitu kapal ambulans. Agar kapal ambulans dapat melakukan tugasnya dengan baik maka kapal tersebut harus memiliki performa yang baik dari segi teknisnya. Salah satu faktor yang mempengaruhi performa kapal yaitu bentuk lambung. Tujuan dari tugas akhir ini yaitu menganalisis pengaruh bentuk lambung terhadap performa kapal ambulans. Variabel bentuk lambung yang digunakan dalam penelitian ini yaitu monohull, katamaran, dan semi trimaran pelat datar. Batasan penelitian untuk performa kapal yaitu terkait dengan hambatan, stabilitas, dan olah gerak kapal. Dari hasil penelitian diperoleh hambatan total terbesar yaitu lambung semi trimaran pelat datar dengan total hambatan 90,9 kilonewton. Diikuti oleh monohull dengan hambatan total sebesar 73,8 kilonewton dan katamaran dengan hambatan total sebesar 59,3 kilonewton. Pada perhitungan stabilitas kondisi muatan penuh model lambung katamaran memiliki nilai lengan pembalik (GZ) maksimum tertinggi yaitu sebesar 2,353 meter pada sudut 20,9 derajat. Semi trimaran memiliki nilai GZ maksimum tertinggi kedua yaitu sebesar 1,472 meter pada sudut 45,5 derajat. Terakhir yaitu monohull yang memiliki nilai GZ maksimum sebesar 1,164 meter pada 40 derajat. Pada perhitungan olah gerak kapal dilakukan pada sudut datang gelombang 0°, 45°, 90°, dan 180° dengan tiga derajat kebebasan (heave, roll, dan pitch). Nilai perpindahan gerakan heaving kapal terbesar dialami oleh model lambung katamaran dengan nilai perpindahan 0,54 meter pada sudut datang gelombang 180 derajat. Nilai rotasi gerakan rolling kapal terbesar dialami oleh model lambung semi trimaran dengan nilai rotasi 8,07 derajat pada sudut datang gelombang 90 derajat. Nilai rotasi gerakan pitching kapal terbesar dialami oleh model lambung monohull dengan nilai rotasi 3,89 derajat pada sudut datang gelombang 0 derajat. ......Indonesia is a country with the most islands in the world with more than 17,000 islands. This is a challenge for the government in distributing health care facilities in each region of Indonesia. Based on data from Perhimpunan Rumah Sakit Seluruh Indonesia (PERSI) in 2020 there were 2,924 hospital units consisting of 60 class A hospitals, 430 class B hospitals, 1,524 class C hospitals, 42 class D hospitals, and other 52 hospitals that have not been categorized. The hospitals in Indonesia is still not evenly distributed. This is evidenced by the map data of the distribution of hospitals which are still centered on the island of Java and Sumatra, while the eastern region of Indonesia is few hospital facilities. One of the health care facilities that suitable with the geographical conditions of Indonesia is an ambulance ship. In order for the ambulance ship to do its job well, the ship must have good performance from a technical point of view. One of the factors that affect the performance of the ship is the form of the hull. The objective of this thesis is to analyze the effect of the hull form on performance of ambulance ship. Hull form variables that used in this study were monohull, catamaran, and flat plate semi trimaran. Research limitations for ship performance are related to drag, stability, and seakeeping. From the results of the study, the largest total resistance was the flat plate semi trimaran hull with a total resistance of 90.9 kilonewtons. Followed by the monohull with a total resistance of 73.8 kilonewtons and the catamaran with a total resistance of 59.3 kilonewtons. In the calculation of the stability of the full load condition, the catamaran hull model has the highest maximum righting arm (GZ) value of 2,353 meters at an angle of 20.9 degrees. Semi trimaran has the second highest maximum GZ value of 1,472 meters at an angle of 45.5 degrees. Finally, the monohull has a maximum GZ value of 1,164 meters at 40 degrees. The calculation of ship motion is carried out at the heading angles of 0°, 45°, 90°, and 180° with three degrees of freedom (heave, roll, and pitch). The largest ship heaving displacement value is experienced by the catamaran hull model of 0.54 meters displacement at 180 degrees heading angle. The largest rotational value of the ship's rolling motion is experienced by the semi-trimaran hull model with a rotation value of 8.07 degrees at heading angle of 90 degrees. The largest ship pitching motion rotation value is experienced by the monohull hull model with a rotation value of 3.89 degrees at heading angle of 0 degrees.

Kapal merupakan salah satu armada angkutan yang memiliki peranan vital. Perdagangan, ekspor-impor, dan industri tidak dapat terlepas dari sarana angkutan berupa kapal. Dalam pengoperasiannya, kapal membutuhkan daya mesin yang sesuai sehingga kecepatan kapal tercapai. Penggunaan bahan bakar yang sehemat mungkin menjadi hal yang sangat penting. Penghematan bahan bakar erat kaitannya dengan hambatan kapal yang terjadi.Penghematan pemakaian energi pada pengoperasian kapal menjadi topik yang menarik dan sangat penting untuk dikaji. Tujuan penelitian ini untuk mencari konfigurasi S/L optimum untuk mendapatkan nilai hambatan terendah sehingga akan mengurangi konsumsi bahan bakar pada saat kapal beroperasi dan membandingkan nilai hambatan yang terjadi pada kapal katamaran dan monohull. Dua buah model kapal catamaran dengan lambung simetris dan variasi rasio jarak lambung S/L 0,2 , 0,3 dan 0,4 digunakan dalam penelitian ini. Metode eksperimen (towing tank) dan numerik (HullSpeed- MaxsurfPro 11.12) dilakukan dalam penelitian denganvariasi kecepatan pada angka Froude 0.2 -1.0. Hasil menunjukkan bahwa hambatan total kapal katamaran terbesar dengan rasio jarak lambung S/L 0,4 terjadi pada Fr < 0,3 dan Fr 0,4 - 1,0. Sedangkan untuk Fn 0,3 - 0,4 nilai koefisien hambatan terbesar dimiliki oleh rasio S/L 0,2 yang ditunjukkan dengan puncak hambatan gelombang paling tinggi (hump resistance). Dari hasil kedua metode menunjukkan bahwa monohull menghasilkan nilai hambatan yang lebih besar daripada katamaran khususnya pada 0.4 ≤ Fn ≤ 0.8. ......Ship is one of the transportion that has a vital role. Trade, exports - imports and industry can't be separated from means of transportation of ship. In operation, the vessel requires engine power accordingly so that the ship's speed is reached. The use of fuel efficient as possible becomes very important. Fuel savings is closely related to resistance vessels occurs. Saving energy consumption on the operation of the ship became an interesting topic and very important to assess. The purpose of this study to look for the configuration S / L optimum to obtain the lowest resistance values so that will reduce fuel consumption when the vessel to operate and compare the value of resistance that occurs in catamaran and monohull.Two models of catamaran with symmetrical and variation of unstagerred demi hulls configuration(S/L) 0.2, 0.3 and 0.4 used in this study. Experimental method (towing tank) and numerical (HullSpeed-MaxsurfPro 11:12) conducted the study with the velocity variations in the Froude number 0.1 -1.0. The results showed that the total resistance of the largest catamaran with unstagerred demihulls configurationS/L 0.4 occurred at Fr <0.3 and Fr 0.4 to 1.0. As for the Fn from 0.3 up to 0.4 the value of the total resistance coefficient of the biggest obstacles is owned by the ratio S/L 0.2 as indicated by the highest peak of the wave resistance (Hump resistance). From the results of both methods showed that the monohull produces greater resistance value than catamaran partially 0.4 ≤ Fn ≤ 0.8.
