Report on Underground Solutions for Urban Problems
No full textWorld wide, we see developing nations building new infrastructure as well as developed cities rehabilitating and expanding their infrastructure to meet the demands of increased population, energy efficiency, and environmental awareness of the public. Ten years ago ITA issued its special edition of the Tribune entitled “Why Go Underground, Contribution of the use of Underground space to Sustainable Development.” Working Group N° 20 of the ITA, focused on Urban Problems and Underground Solutions, has continued examining the use of underground space in the urban environment as it evolves with expanding cities and urban densification. This report present examples of the uses of underground space in cities, trends in Metro and roadway planning, and gives an overview of aspects to be considered during the decision making process, in order to optimally include underground solutions.Geoscience & EngineeringCivil Engineering and Geoscience
Detachable Steerable Clip Applier for Dissection of ITA Branches
No full textThe internal thoracic artery (ITA) is increasingly being recognized as the best conduit for replacement of diseased coronary arteries. As the ITA is the main blood supply for the sternum, harvesting this artery causes a drop in blood flow, increasing the risk of failing to heal, and risking deep sternal wound infection. Current methods of harvesting the ITA are time consuming, and due to hidden arteries the manoeuvrability of the surgeon is limited. In this project the goal is to develop a new instrument for branch sealing and dissection, that increases the maneuverability, minimizes damage to surrounding tissue while beingmore time efficient. A systematical selection process resulted in the solutions for some of the sub-functions, whereas two subfunctions required more thorough analysis and evaluation. Concept selection for the sub-function Tip-Articulation a more in-depth analysis and experimental evaluation (n=19). The selection of the sub-function Handle-Mechanism is done by analysis of proven concepts, choices are based on the requirements that resulted from consultation with an experienced surgeon from LUMC, literature study, and supervision of experienced medical instrument engineers. A preliminary headroom analysis is done, resulting in an estimated drop of 64.45%for the duration of sealing and dissecting of branches with a relatively bigger diameter. Further research should specifically be aimed on the further development of the chosen concepts

POLA PERTUMBUHAN, RESPON OSMOTIK DAN TINGKAT KEMATANGAN GONAD KERANG Polymesoda erosa DI PERAIRAN TELUK YOUTEFA JAYAPURA PAPUA
No full textKerang Polymesoda erosa (nama lokal kerang kodok) termasuk kelas bivalve yang banyak
ditemukan di perairan Teluk Youtefa Jayapura. Kerang ini hidup di daerah lumpur, lumpur
berpasir dan serasah mangrove yang telah terdekomposisi menjadi lumpur. Habitat hidup
kerang Polymesoda erosa terganggu akibat aktivitas antropogenik oleh masyarakat
setempat seperti penebangan hutan mangrove, bahan pencemar, sedimentasi dan
penangkapan kerang yang tidak terkontrol. Tujuan penelitain ini adalah mengetahui pola
pertumbuhan, respon osmotik dan tingkat kematangan gonad melalui studi histologi.
Seratus tiga puluh tiga (133) sampel kerang P.erosa dikumpulkan dari tiga stasiun berbeda
selama bulan juni 2016. Hubungan morfometri panjang berat dianalisis menggunakan
analisis regresi linearitas sederhana dan korelasi. Hasil penelitian menunjukan jumlah kelas
frekuensi panjang tertinggi kerang P.erosa adalah 50,56–56,56 mm dengan kisaran ukuran
29,56-85,65 mm. Pola pertumbuhan kerang P.erosa adalah alometri positif terhadap 50
individu kerang jantan, 55 individu kerang betina dan 28 individu kerang unidentified
(UND). Respon osmotik kerang P.erosa terdiri dari dua pola yaitu hipoosmotik dan
hiperosmotik. Hasil studi histologi tingkat kematangan gonad kerang P.erosa ditemukan
tiga tingkatan yaitu TKG I, TKG II, TKG III dan gonad yang tidak dapat dibedakan jantan
atau betina (unidentified)

Pengaruh Kascing dan Pupuk Anorganik Terhadap Ketersediaan Nitrogen pada
Alfisols Jumantono dan Serapannya oleh Tanaman Jagung Manis (Zea mays L.
Saccharata). Dibawah bimbingan Ir. Sri Hartati, MP.; Hery Widijanto, SP. MP.;
Dr. Ir. Widyatmani Sih Dewi, MP.
Kondisi fisik tanah Alfisol pada umumnya strukturnya remah, aerasi dan
drainase lancar, namun ketersediaan N rendah karena mengalami pencucian
intensif. Tanaman jagung manis memerlukan N untuk pembentukan protein,
klorofil, dan bagian vegetatif tanaman. Rata-rata tanaman jagung manis
membutuhkan N 90-120 kg/ha, oleh karena itu perlu ditambahkan N dalam bentuk
pupuk. Pupuk yang ditambahkan yaitu kascing dan pupuk anorganik.
Mikroorganisme yang terdapat dalam kascing mampu mengikat N untuk
sementara waktu dalam bentuk organik, sehingga dapat menekan laju pencucian
nitrat, dengan demikian dapat meningkatkan kandungan N tanah Alfisol dan
serapannya oleh tanaman guna meningkatkan pertumbuhan jagung manis.
Penelitian ini dilakasanakan dari bulan September 2007 sampai dengan
Januari 2008 di Kecamatan Jumantono, Kabupaten Karanganyar, serta analisis
tanah dan jaringan tanaman dilaksanakan di Laboratorium Kimia dan Kesuburan
Tanah Fakultas Pertanian Universitas Sebelas Maret Surakarta. Penelitian ini
bertujuan untuk mengetahui pengaruh pemberian kascing dan pupuk anorganik
terhadap ketersediaan nitrogen pada Alfisols Jumantono dan serapannya oleh
tanaman jagung manis (Zea mays L. saccharata).
Penelitian ini merupakan penelitian eksperimental dengan menggunakan
Rancangan Acak Kelompok Lengkap (RAKL) faktorial dengan dua faktor. Faktor
pertama adalah dosis kascing dan faktor kedua adalah dosis pupuk anorganik
(urea, SP 36, KCl). Faktor I terdiri atas 3 taraf yaitu: K0 (tanpa kascing), K1
(kascing 1,5 ton/ha), K2 (kascing 3 ton/ha). Faktor II terdiri atas atas 3 taraf yaitu:
A0 (tanpa pupuk anorganik), K1 (urea 100 kg/ha, SP 36 50 kg/ha, KCl 25 kg/ha),
A2 (urea 200 kg/ha, SP 36 100 kg/ha, KCl 50 kg/ha). Dari kedua faktor tersebut
diperoleh 9 kombinasi perlakuan dan masing-masing kombinasi perlakuan diulang
sebanyak 3 kali. Analisis statistika menggunakan Uji F, Kruskal Wallis, DMRT,
Mood Median, dan Korelasi.
Hasil Penelitian menunjukkan bahwa terdapat interaksi antara kascing dan
pupuk anorganik yang meningkatkan ketersediaan nitrogen pada Alfisols dan
serapannya oleh tanaman jagung manis. N tersedia tertinggi ditunjukkan oleh
pemberian kascing 3 ton/ha + urea 200 kg/ha, SP 36 100 kg/ha, KCl 50 kg/ha
yaitu 0,095%. Nilai serapan N dan N jaringan tanaman tertinggi yaitu 0,714
g/tanaman dan 1,39% ditunjukkan oleh interaksi pemberian kascing 3 ton/ha dan
tanpa penambahan pupuk anorganik. N total tertinggi ditunjukkan oleh pemberian
urea 200 kg/ha, SP 36 100 kg/ha, KCl 50 kg/ha yaitu 0,30%.

The Role Of Organizational Supporting In Moderating The Whistleblowing Behavior Intention
No full textThis study aimed to analyze the influence of the attitude toward behaviour and perceived behavioural control on whistleblowing intention, and the role of organizational supporting of employees as moderating variable in the influence of the attitude toward behaviour and perceived behavioural control on whistleblowing intention of employees. This study used primary data from a questionnaire, simple random sampling method and quantitative approach of Moderate Regression Analysis (MRA) technique. This study empirically showed that the implementation of the whistleblowing system has not been successful. Based on the three hypotheses proposed, all of them were not proven and accepted. The attitude toward behaviour has no significant effect on whistleblowing intention by the employees. The perceived behavioural control had a significant effect on whistleblowing intention by employees. In other that, the current organizational support of employees can not play a role as moderation influencing attitudes and perceived behavioural control over internal whistleblowing intention. The government needs to create special laws and rules to give enough law protection for the whistleblo¬wer in the public sector
Analysis of the Level of Satisfaction and Importance among Trainees towards Distance Training in the Covid-19 Pandemic Era
No full textThis study aims to analyze the level of satisfaction and importance among trainees towards distance training and identify the strengths and weaknesses of distance training implementation so that the organizers can maximize the satisfaction of the trainees towards the implementation of distance training. This research used quantitative and qualitative analysis within the framework of Level 1 (Reaction) of the Kirkpatrik Evaluation Model, as well as the Importance Performance Analysis (IPA) method. The results showed that: (1) the trainees were very satisfied with the implementation of distance training; (2) the implementation of distance training is considered very important to be implemented; (3) Some evaluation indicators have positive gap values, while others have negative gap values, meaning that some evaluation indicators have not met the expectations of stakeholders; and (4) most evaluation indicators are in quadrants A and B, meaning that they either must be prioritized to improve the performance, or maintained because they are already considered good. Therefore, the Financial Education and Training Agency through work units in the region, especially the Makassar branch, needs to improve the performance of distance training implementation, especially in the evaluation items/indicators in quadrant A to increase the satisfaction of participants in the next training sessions
