ANALISIS EFISIENSI BOILER TERHADAP POLA PENGOPERASIAN SOOTBLOWER DI PLTU SURALAYA
Authors: Dwiaji Yudhi Chandra , Utama Didik Margi 
Published: July 2021

Perusahaan Listrik Negara (Persero) PT announced electricity consumption in the first half of 2018 was 112.46 TeraWatt hour (TWh) or grew 4.7 percent on an annual basis. With the continued increase in electricity demand, electricity providers are required to be able to provide reliable, stable and efficient electricity production to the public. High efficiency in an electricity production in a power plant can be seen from the performance or efficiency of the boiler, because the power of a boiler is the same as the power of a power plant. The boiler efficiency is obtained from calculating the ratio between the output energy and the boiler input energy. Boiler efficiency is influenced by the cleanliness of the boiler from coal ash deposits. Cleaning can be done by operating the sootblower. The sootblower operation method will affect the value of boiler efficiency which gives an idea of how much efficiency the boiler when the boiler is operating. As based on the analysis of the calculations that have been made, the results of the boiler efficiency decrease when the sootblower is operating. The highest decrease in boiler efficiency during the sootblower process is 2.22%, the lowest decrease in boiler efficiency during the process is 1.08% and the average decrease during the sootblower process is 1.73%. While the impact of sootblower operation, boiler efficiency has decreased 11 times and has increased 8 times, indicating that the sootblower operating method in PLTU Suralaya is not effective.
Mitigasi karakter muka air banjir dari morfometri DAS Wai Loning – Negeri Laha, berbasis Geographic Information System (GIS)
Authors: Pattiselanno Steanly Reynold. R. 
Published: July 2021

Karakter sungai di Pulau Ambon memiliki ciri hanya satu aliran sungai utama dari hulu ke hilir ataupun satu aliran sungai utama yang akan terbagi menjadi beberapa anak sungai di arah hilir. Ini berbeda dengan karakter sungai Wai Loning yang membelah Negeri Laha yang menerima aliran dari dua sungai utama lainnya yaitu Wai Sakula dan Wai Tengah, yang menyebabkan potensi debit banjirnya menjadi berkali lipat lebih banyak terutama di musim hujan.Berdasarkan hal tersebut, maka diperlukan suatu kajian studi penelitian tentang potensi karakter muka air banjir aliran sungai pada DAS yang dibentuk oleh kesatuan aliran Wai Sakula – Wai Tengah – Wai Loning, yang pastinya membutuhkan survey kawasan DAS demi mengumpulkan parameter morfometri DAS. Data teknis yang diperlukan untuk DAS Wai Loning berupa morfometri sungai yang meliputi: luas DAS, panjang DAS, lebar DAS, kemiringan data gradien sungai, orde dan tingkat percabangan sungai, kerapatan sungai, dan bentuk DAS.Berdasarkan hasil identifikasi data WRb= 12,33 dan Rc = 0,25, maka DAS Wai Loning yang terbentang antara 3°40’6,51” - 3°43’19,50” LS dan 128°1’17,20” - 128°5’26,98” BT dengan luas 35.674.050,00 m2 (35,67 km2) atau 3.567,405 Ha, dan keliling 41.990,00 m (41,99 km) termasuk karakter DAS dimana sungainya mengalami kenaikan dan penurunan muka air banjir yang berlangsung dengan cepat serta karakter debit puncak yang datang dengan cepat, begitu juga penurunannya.
PENGARUH INTENSITAS CURAH HUJAN TERHADAP TINGKAT INFILTRASI PADA ECO-CONCRETE PAVING BLOCK

Published: July 2021

Eco-concrete paving block adalah bata beton yang dirancang khusus untuk perkerasan jalan, yang diaplikasikan sebagai lapis permukaan perkerasan permeable. Gap/siar antar paving dibuat tembus air, dan diisi dengan pasir. Hal ini dimaksudkan untuk mereduksi limpasan aliran permukaan (runoff) guna meminimalkan kemampuan limpasan aliran permukaan mengangkut zat polutan dari permukaan tangkapan yang dapat membahayakan daerah hilir, untuk meningkatkan kualitas air di badan air. Jadi, eco-concrete paving block adalah paving block beton yang digunakan untuk lapis permukaan perkerasan permeabel, yang penerapannya memanfaatkan teknologi ramah lingkungan. Permasalahan penelitian adalah bagaimana pengaruh intensitas curah hujan terhadap kapasitas infiltrasi eco-concrete paving block? dan interaksinya dengan geometri/bentuk paving, dan kemiringan perkerasan. Sementara itu, tujuan penelitian adalah untuk mengevaluasi pengaruh intensitas curah hujan terhadap kapasitas infiltrasi dari eco-concrete paving block, dengan mempertimbangkan variabel-variabel berikut: bentuk paving, intensitas curah hujan, dan sudut kemiringan perkerasan. Penelitian dilaksanakan di laboratorium, dengan mengembangkan perangkat uji: box uji infiltrasi berukuran 1m2; modified rainfall simulator untuk mendapatkan intensitas curah hujan 75mm/jam, 175mm/jam dan 275mm/jam. Hasil penelitian menunjukkan bahwa kapasitas infiltrasi dari perkerasan sangat dipengaruhi oleh intensitas curah hujan dan bentuk paving; pada intensitas curah hujan rendah tidak terjadi runoff pada semua bentuk paving yang diuji.
Beauty Filters Are Changing the Way Young Girls See Themselves
Authors: Ryan-Mosley Tate 
Published: July 2021

VERONICA STARTED USING filters to edit pictures of herself on social media when she was 14 years old. She remembers everyone in her middle school being excited by the technology when it became available, and they had fun playing with it. “It was kind of a joke,” she says. “People weren’t trying to look good when they used the filters.”
But her younger sister, Sophia, who was a fifth grader at the time, disagrees. “I definitely was—me and my friends definitely were,” she says. “Twelve-year-old girls having access to something that makes you not look like you’re 12? Like, that’s the coolest thing ever. You feel so pretty.”

I contratti di programma: una questione di multitask?
Authors: Nisticň Rosanna 
Published: July 2021

- In the light of the results from a wide empirical investigation, this essay examines some crucial characteristics of the Italian policy measure called Contratti di programma through both the analytical framework of the incomplete contracts literature and the multi-task Principal-Agent theory. The Contratti di programma policy is based on a formal agreement between the Italian Government and private firms to carry on an investment programme comprising a number of different projects (industrial investments; workers training programs; research centres and projects). The essay also provides a number of suggestions for improving the effectiveness of this policy.

Struttura economico-finanziaria dell'industria italiana: ruolo degli incentivi pubblici
Authors: Gallo Riccardo , Carapellotti Fabrizio 
Published: July 2021

- Italian government's grants to industrial companies have decreased in recent years. Moreover, during the period 2000-2007, less than 25% of total incentives was aimed at sustaining industrial R&D and internationalization activities. In the absence of an effective public aid policy, in 2007 Italian industrial companies were still focused on traditional manufacturing industries and were suffering the increasing competition from emerging countries. The added value of their manufacturing activity has decreased, their technological growth has slowed down, their financial indebtedness has dropped, while their return on equity has increased. The performance of most industrial companies that had received the government's aids has not improved, with the exception of the so-called Made in Italy and the Transportation equipment manufacturing sectors, whose economic performance has improved with state subsidies.

Le multinazionali dei paesi emergenti: gli investimenti cinesi in Italia
Authors: Spigarelli Francesca 
Published: July 2021

This paper focuses on a recent phenomenon: the Chinese Go global policy, which encourages domestic firms to enter the global competition through active internationalization processes. At present, Chinese investments are still small compared to the world value of outward foreign direct investments, but it is interesting to focus on their trends and skyrocketing growth. The attention is drawn to the Italian case. Italy is still not playing a major role in Chinese companies' internationalization strategies. Flows and stocks of investments are low and only a small number of companies is investing in Italy. But things are changing quickly. Italy is becoming increasingly interesting for Chinese companies aiming to acquire brands, knowledge and specific competencies, as well as strategic locations to penetrate European markets. The small dimension of the target companies (for acquisitions) encourage Chinese investors to come to Italy. Data on Chinese investments flows, on individual entrepreneurs, as well as on Chinese companies operating in Italy are discussed and analyzed to build a framework to test some preliminary hypotheses and to verify the interest for further research projects. .

Le societŕ controllate dai maggiorni comuni italiani: qualitŕ ed efficienza nella fornitura dei servizi
Authors: Barbaresco Gabriele 
Published: July 2021

- Calculation and comparison of quality and efficiency indicators in the provision of local public services have been a relatively neglected field of research in industrial economics. Even the regulatory bodies, if any, which supervise these sectors, have generally failed to construct rigorous and exhaustive databases, and therefore lack what would be an essential tool to exercise their power as regulators. An incomplete and unclear picture emerges, where what little available information there is, is to be found in the "charters of service" drawn up by the companies themselves using selfreferential codes and methodologies that are neither shared nor controlled. The lack of transparence in information terms often goes hand-in-hand with operating inefficiencies, which can be perpetrated more easily in the absence of suitable benchmarking activity. This article seeks to provide an account of an extensive research project to collect and compile quality and efficiency indicators which the Mediobanca Research Department has carried out on behalf of the Civicum Foundation with reference to local public service operators controlled by six of the leading Italian municipalities (Bologna, Brescia, Milan, Naples, Rome and Turin) between 2003 and 2007. .

Dimensione e concentrazione dei gruppi bancari italiani nell'ultimo decennio
Authors: Cerasi Vittoria , Crosato Lisa 
Published: July 2021

- The paper analyzes the change in the size distribution of Italian banking groups over the period 1999 to 2007 following a wave of M&As among large banks. Had this process increased the degree of concentration we would have expected greater credit rationing for small firms, given the central role of Italian banks in financing small firms. We measure this change through widely used measures of concentration on branches. First, we observe a steady increase in concentration that can be captured only by looking at the overall size distribution. Other measures do not perceive this change until the year 2007, when the very large banks merged. Second, by focusing on the banking groups that have been active players in M&As we do see a decline in concentration, since smaller players have caught up with the larger ones in terms of rate of size increase. This contrasts with the role of the new entries and the disappearance of banks following mergers, that has increased the dispersion of market shares. The implications are that: i) there is a credit termination risk due to the rise in active players' size, but ii) credit rationing may not occur due to a substitution effect in credit supply from new entries.

Esperienza lavorativa dei fondatori e sopravvivenza delle giovani imprese high-tech in mercati in crisi
Authors: Grilli Luca 
Published: July 2021

- This article adds new insights into the relationship between the founders' human capital and the survival prospects of start-up businesses. The impact of founders' human capital on firm survival is controversial. On the one hand, more experienced and skilled individuals are likely to create start-up businesses with a high chance of survival; on the other hand, their opportunity costs to run the firm may be high given the potential returns for investing their efforts in alternative employment opportunities. Analysing a sample of 179 Italian start-up companies created during 1995-early 2000 and operating in the ICT services markets, this study provides evidence that, in intense industry crises (early 2000-2003), highly work-experienced entrepreneurs may pursue an exit strategy, highlighting the importance of distinguishing between different types of work experience and different exit routes. In particular, founding teams with highly specific work experience show higher probability of following the M&A route, while a higher level of generic work experience is more conducive to closure.

Published: July 2021

Peningkatan kasus HIV/AIDS tidak terlepas dari adanya stigma dan diskriminasi pada pengidap yang dapat menjadi penghalang utama terhadap pencegahan, pengobatan, dan akses terkait layanan kesehatan. Berdasarkan data YPKDS, kota Makassar menduduki peringkat pertama jumlah kasus HIV/AIDS sebanyak 2885 kasus. Penelitian ini bertujuan untuk mengetahui hubungan dukungan sosial terhadap kualitas hidup ODHIV. Jenis penelitian yang digunakan adalah penelitian kuantitatif dengan rancangan cross sectional study. Sampel dalam penelitian ini yaitu semua pasangan positif HIV sebanyak 43 responden dengan teknik sampling jenuh. Metode analisis data dalam penelitian ini terdiri dari analisis univariat, analisis bivariat untuk mengetahui hubungan antara variabel independen dan variabel dependen dengan menggunkan uji statistik chi-square, serta analisis multivariat untuk melihat dukungan yang paling dominan berhubungan dengan kualitas hidup ODHIV dengan menggunakan uji regresi logistik berganda. Hasil penelitian menunjukkan bahwa variabel yang berhubungan dengan kualitas hidup ODHIV adalah dukungan keluarga (p = 0,010 dan OR = 7,280), dukungan teman (non ODHIV) (p = 0,010), dan dukungan kelompok sebaya (p = 0,028) sedangkan yang tidak berhubungan yaitu dukungan pasangan (p = 255). Dari hasil penelitian ini dapat disimpulkan bahwa dukungan keluarga, teman dan kelompok sebaya merupakan variabel yang berhubungan dengan kualitas hidup ODHIV dan dukungan keluarga merupakan variabel yang paling mendukung sebanyak 7,280 kali terhadap kualitas hidup ODHIV di Yayasan Peduli Kelompok Dukungan Sebaya Makassar. Saran dari penelitian ini yaitu tidak melakukan stigma dan diskriminasi kepada ODHIV, melainkan memberikan dukungan kepada mereka agar tetap semangat karena yang perlu dihindari bukan orangnya tetapi virusnya dan hal-hal yang dapat menyebabkan terjadinya penularan HIV.

Background: Utilisation of the Endoscopic Vein Harvesting (EVH) technique has been increasing for coronary artery bypass grafting (CABG) for the last two decades. Some surgeons remain concerned about the long-term patency of the long saphenous vein harvested endoscopically compared to traditional Open Vein Harvesting (OVH). The aim of this study was to perform a retrospective analysis of the outcomes between EVH and OVH from three UK centres with 10 years follow-up. Methods: 27,024 patients underwent CABG with long saphenous vein harvested by EVH (n=13,794) or OVH (n=13,230) in three UK centres between 2007 and 2019. Propensity modelling was used to calculate the Inverse Probability of Treatment Weights (IPTW). The primary endpoint was mortality from all causes and secondary endpoints were length of hospital stay, postoperative complications, and incidence of repeat coronary re-vascularisation for symptomatic patients. IPTW was used to balance the two intervention groups for baseline and preoperative co-morbidities. Results: Median follow-up time was 4.54 years for EVH and 6.00 years for OVH. Death from any cause occurred in 13.8% of the EVH group versus 20.8% in the OVH group over the follow-up period. The hazard ratio of death (EVH to OVH) was 0.823 (95% CI: 0.767, 0.884). Length of hospital stay was similar between the groups (p=0.86). Post-operative pulmonary complications were more common in EVH vs OVH (14.7% vs. 12.8%, p<0.001), but repeat coronary re-vascularisation was similar between the groups. Conclusion: This large retrospective multicentre analysis indicates that EVH has a lower risk of mortality compared with OVH during the follow-up period of the study. The observed benefits of EVH may outweigh the risks but should be considered on a case-by-case basis. We hope this review gives confidence to other cardiac centres that offering an EVH approach to conduit harvesting does not affect long term patient outcomes.
Measuring Social License to Operate the Infrastructure Project in Bangladesh
Authors: Morshed Md Manjur , Arafin Zaki , Nafi Salima Khan 
Published: July 2021

Social license to operate is a measure to engage with and gain acceptance from the stakeholders for large infrastructure projects. The object of this study is to measure social license to operate an infrastructure project in Khulna city, Bangladesh. Predicated on an established model, 16 statements were selected as the basis for measuring the social license to operate. A questionnaire survey was conducted among 44 local stakeholders. Using varimax rotation, five different components were identified: socio-political, economic, procedural fairness, interactional trust, and institutional trust. The model was statistically tested and found to be a medium fit explaining the results. The findings are that the project has gained socio-political, economic, procedural fairness, and interactional trust of the stakeholders, yet lacks institutional trust factor to achieve a social license to operate. The paper recommends the inclusion of the social license to operate concept in infrastructure planning and implementation phases in Bangladesh.
