"The shipbuilding industry is characterized by high-risk business activities; therefore, caution should be taken in its operational processes. From upstream to downstream, the shipbuilding industry depends on other industries. In this study, a risk assessment was conducted on the construction of new vessels using the Bayesian network approach; accordingly, the risk assessment was carried out using a probabilistic value at risk (VaR). The study was carried out by PT PAL Indonesia in association with the construction of a new tanker ship (building production codes M271 and M272). An analysis was conducted on three main components of new vessel construction—design components, material and production components, and subcomponents of the previous two components. From the study, we could conclude that the probability of delay for new vessel construction caused by design delay is 0.05; the probability of delay caused by material delay is 0.65; and the probability of delay caused by production delay is 0.3. For delays caused by design factors, a yard plan is the sub-component that contributes predominantly to delays (i.e., probability of 0.3). For delays caused by material factors, the sub-component with the greatest impact is hull and machinery outfitting, with a probability of 0.3. For delays caused by production factors, the sub-component with the biggest impact is hull construction, with a probability of 0.39. Thus, we could conclude that a project delay would occur if the material component and the hull construction sub-components were not handled properly."

"Industri pertambangan dapat secara aktif berkontribusi pada sustainable development dengan mengurangi dampak negatif terhadap degradasi lingkungan, seperti kegagalan peralatan. Penggunaan sianida dalam metode heap leaching untuk ekstraksi emas merupakan salah satu cara untuk memperoleh recovery yang lebih tinggi dan lebih ramah lingkungan dibandingkan penggunaan merkuri.

The mining industry can actively contribute to sustainable development by reducing negative impacts on environmental degradation, such as equipment failure. For example, using cyanide in the heap leaching method for gold extraction is a way to obtain a higher recovery and is more environmentally friendly than mercury. Furthermore, using the risk-based inspection (RBI) method according to API 581 standard with a semi-quantitative approach, it is possible to calculate the probability and consequence of failure that will occur in heap-leaching irrigation pipes. This research aims to determine the optimal inspection plan for heap-leaching irrigation pipes and their level of risk. A risk-based inspection is carried out on a 12-inch heap leaching irrigation pipe for which the data is obtained from the thickness measurement results. The application of semi-quantitative risk-based inspection (RBI), according to API 581 standard, can determine a more optimal inspection schedule plan and reduce the level of risk on research object equipment compared to time-based inspection methods. Research conducted on data analysis of inspection results for risk-based inspection (RBI), obtained data taken at the pipe elbow position where there is a reduction in pipe wall thickness of 0.97 mm per year which has a Probability of Failure (PoF) value of 2 and Consequence of Failure (CoF) at level D with potential business interruption consequences of US$958,506, resulting in a risk level in 2D or medium level. Therefore, inspection scheduling is determined based on the level of risk and the remaining life of the pipe to prevent achieving/exceeding the risk target (minimum thickness)."

"Keterbatasan cakupan layanan penyediaan air oleh PDAM menyebabkan kebanyakan warga Indonesia menggunakan sumber air lain untuk kebutuhan air minum. Dua jenis sumber air minum yang paling banyak digunakan di Indonesia, termasuk di Kota Bekasi dan Metro, adalah air tanah dan air isi ulang. Namun, air tanah dan air isi ulang memiliki risiko kesehatan akibat kontaminasi patogen yang dikarenakan berbagai faktor termasuk pengolahan air yang tidak memadai dan penyimpanan yang tidak higienis. Studi ini dilakukan untuk menganalisis persebaran kontaminasi E. coli pada air minum di Kota Bekasi dan Metro, melihat korelasi antara beberapa faktor dengan kontaminasi E. coli, serta membandingkan risiko kesehatan antara konsumsi air tanah dan air isi ulang menggunakan metode Quantitative Microbial Risk Assessment (QMRA). Survei lapangan serta pengambilan sampel air sumber dan air minum dilakukan pada 174 rumah tangga di Kota Bekasi dan Metro. Pengujian kualitas sampel air dilakukan menggunakan metode Most Probable Number (MPN). Dari 174 sampel air minum, 31,8% ditemukan terkontaminasi E. coli. Rata-rata konsentrasi E. coli di Kota Bekasi sebesar 32,2 MPN/100 ml dan di Kota Metro sebesar 106,4 MPN/100 ml melebihi baku mutu air minum Permenkes No.492 tahun 2010. Berdasarkan uji Wilcoxon, terdapat perbedaan signifikan antara konsentrasi E. coli sebelum dan setelah dimasak (P<0,01). Berdasarkan uji Spearman dan odds ratio, tidak ada korelasi signifikan antara sumber air, metode pengolahan, wadah penyimpanan, waktu penyimpanan, dan suhu terhadap kontaminasi E. coli di air minum. Konsumsi air isi ulang memiliki beban penyakit gastrointestinal tahunan yang lebih rendah dibandingkan air tanah dengan nilai median beban penyakit 7,30 x 10-5 DALY/orang/tahun, dibandingkan dengan 1,16 x 10-4 DALY/orang/tahun pada konsumsi air tanah. Namun, kedua sumber air minum belum memenuhi batas aman risiko beban penyakit WHO. Studi ini menunjukkan bahwa air tanah dan air isi ulang masih belum aman untuk dikonsumsi, sehingga intervensi diperlukan untuk mencegah risiko kesehatan lebih lanjut.

Due to the limited coverage of water supply services by PDAM, most Indonesians use other sources for their drinking water needs. The two types of drinking water sources that are widely used in Indonesia, including in Bekasi and Metro cities, are groundwater and refill water. However, groundwater and refill water pose health risks due to pathogen contamination caused by numerous factors including inadequate water treatment and unhygienic storage. This study was conducted to analyze the distribution of drinking water E. coli contamination in Bekasi and Metro cities, to analyze correlations between several factors and E. coli contamination, and to compare the health risks between groundwater consumption and refill water using the Quantitative Microbial Risk Assessment (QMRA) method. Field surveys and source water and drinking water sampling were carried out on 174 households in Bekasi and Metro cities. Water sample quality analysis was carried out using the Most Probable Number (MPN) method. Of the 174 drinking water samples, 31.8% were found to be contaminated with E. coli. The mean E. coli count of 32,2 MPN/100 ml in Bekasi City and 106,4 MPN/100 ml in Metro City both exceeded the drinking water quality standard of Permenkes No.492 2010. Based on the Wilcoxon test, there was a significant difference between the E. coli count before and after boiling (P <0.01). Spearman and the odds ratio analysis revealed no significant correlation between water sources, treatment methods, storage containers, storage time, and temperature to E. coli contamination in drinking water. Consumption of refill water has a lower annual gastrointestinal disease burden than groundwater with a median disease burden of 7.30 x 10-5 DALY/person/year, compared to 1.16 x 10-4 DALY/person/year for groundwater consumption. However, the both drinking water sources did not meet the safe threshold for the WHO disease burden. This study demonstrated that groundwater and refill water is still not safe for consumption, thus intervention is necessary to prevent further health risks."

First, this study performed a literature review to identify risk criteria in the plastic manufacturing Supply Chain's circular economy initiative. Second, it continued by interviewing the Experts to validate the identified risks. Right Experts are involved in rating the criteria on a four-point integer scale. From Expert appraisal, this study established eight risk categories and 31 specific risks using DEMATEL based-ANP. There are specific risks with the greatest influence in the application of a circular economy, they are transparency of information, information systems supporting governance, social responsibility, environmental impact and standardization."

"Rendahnya daya saing Industri Galangan Kapal Nasional dipicu oleh tingginya angka impor kapal ke Indonesia yang bahkan tidak mencapai 2% per Oktober 2021. Hal ini terjadi karena membangun kapal di Indonesia relatif lebih lama dan mahal. Kendala yang dihadapi adalah tingginya komponen kapal impor yang mencapai 70%-80%. Melihat pengaruh komponen kapal impor terhadap daya saing Industri Galangan Kapal Nasional, maka penting untuk meminimalisir dan mengendalikan risiko agar proses pengadaan efektif dan efisien. Tujuan penelitian ini adalah untuk mengidentifikasi penyebab risiko prioritas dan mitigasi risiko prioritas. Penelitian ini menggunakan metode SCOR (Supply Chain Operations Reference) dan HOR (House of Risk). Hasil penelitian menunjukan bahwa risk agent prioritas adalah kualifikasi SDM galangan tidak memadai, perencanaan terkait tidak akurat, dan komitmen supplier kurang; PA (Preventive Action) prioritas adalah membuat database komponen kapal impor untuk internal galangan dan rutin diperbarui, membangun hubungan yang erat dengan menjalin komunikasi yang baik dengan seluruh pihak yang terlibat, melakukan pemilihan SDM yang berkompeten dibidangnya.

The low competitiveness of the National Shipbuilding Industry is caused by the high number of imported ships to Indonesia which doesn’t even reach 2% as of October 2021. This is because building ships in Indonesia is relatively longer and more expensive. The constraint faced is the high percentage of imported ship components, which reach 70%-80%. Considering the influence of imported ship components on the competitiveness of the National Shipbuilding Industry, it is important to minimize and control risks for an effective and efficient procurement process. The purpose of this study is to identify priority risk agents and preventive actions. This study uses the SCOR (Supply Chain Operations Reference) and HOR (House of Risk) methods. The results of the study show that the priority risk agents are the inadequate qualification of shipyard human resources, inaccurate related planning, and the lack of supplier's commitment; priority preventive actions are creating database of imported ship components for the shipyard's internal use and regularly updated, building close relationships by establishing good communication with all parties involved, and selecting competent human resources in their respective fields."

"Integrated Collection System (ICS) merupakan sebuah sistem pengumpulan data kegiatan survei atau sensus yang dikelola oleh Badan XYZ. Melalui ICS, Badan XYZ dapat mempercepat proses kegiatan statistik tanpa mengurangi kualitas data yang dihasilkan. Akan tetapi, ICS juga mempunyai isu dalam hal keamanan informasi yaitu terdapat celah-celah kerentanan yang dapat dieksploitasi oleh suatu serangan siber. Untuk menangani permasalahan tersebut, penelitian ini bertujuan untuk mengusulkan pengembangan metode penilaian risiko keamanan informasi dengan menggunakan model Bayesian Attack Graphs (BAG). Penilaian risiko dengan menggunakan model BAG dinilai cocok untuk menilai paparan risiko pada serangan siber yang menargetkan celah kerentanan. Sebagai kontribusi keilmuan, penelitian ini mengusulkan formulasi penilaian risiko menggunakan dua faktor risiko, faktor likelihood dan faktor impact. Metrik likelihood memakai EPSS, sedangkan metrik impact memakai sub skor impact CVSS. Melalui pengembangan metode penilaian yang diusulkan, diperoleh nilai rata-rata nilai paparan risiko pada infrastruktur ICS sebesar 0.365. Dengan demikian, paparan risiko pada infrastruktur ICS berkategori Low, sehingga paparan risiko serangan berantai melalui celah-celah kerentanan pada infrastruktur ICS dapat dikatakan rendah. Dengan adanya output dari penelitian ini, model penilaian risiko melalui pengembangan model BAG dapat menilai lebih akurat suatu paparan risiko serangan siber melalui celah-celah kerentanan di suatu sistem.

The Integrated Collection System (ICS) is a statistics data collection system managed by XYZ Agency. Through ICS, the organization can speed up the process of statistical activities without reducing the quality of the data it produces. However, ICS also has issues in terms of information security, namely that there are vulnerabilities that can be exploited by cyberattacks. To address these problems, this study aims to propose the development of an information security risk assessment method using the Bayesian Attack Graphs (BAG) model. Risk assessment using the BAG model is considered suitable for assessing risk exposure to cyberattacks that target device vulnerabilities. As a contribution, this research proposes the formulation of a risk assessment using two risk factors, the likelihood factor and the impact factor. The likelihood metric uses EPSS, while the impact metric uses the CVSS impact sub-score. Through the development of the proposed valuation method, the average risk exposure value for the ICS infrastructure is 0.365. Thus, the risk exposure to the ICS infrastructure is in the Low category, so that the risk exposure to chain attacks through vulnerabilities in the ICS infrastructure can be said to be low. With the output of this study, the risk assessment model through the development of the BAG model can more accurately assess an exposure to the risk of cyberattacks through vulnerabilities in a system."

"Indonesia merupakan negara kedua terburuk dalam hal pengelolaan limbah plastik di dunia. Kebanyakan plastik di Indonesia dibakar secara terbuka dan ditimbun begitu saja. Pemerintah Indonesia sudah memiliki rencana penanganan yakni dengan melipatgandakan laju daur ulang. Oleh karena itu, perlu diketahui seberapa besar dampak lingkungan yang dihasilkan dari proses daur ulang yang dilakukan di Indonesia. Maka, penelitian ini dilakukan untuk menganalisis dampak lingkungan yang dihasilkan dari proses daur ulang plastik polyethylene terephthalate dengan menggunakan metode life cycle assessment. Terdapat dua faktor terbesar yang menyebabkan dampak lingkungan pada proses daur ulang PET yakni, penggunaan maupun pembakaran bahan bakar fosil sebagai sumber energi serta pengelolaan limbah air dan bahan kimia sisa produksi yang kurang baik. Kedua faktor tersebut merupakan masalah utama yang harus diperbaiki untuk dapat menghasilkan potensi dampak lingkungan seminimal mungkin. Sehingga, perbaikan proses daur ulang PET dapat dimulai dengan memitigasi kedua faktor tersebut.

Indonesia is the second worst country in the world in terms of plastic waste management. Most plastic waste in Indonesia ended up being openly burned and in landfill. Indonesian government already made a strategic plan in handling this problem by doubling the recycling rate. Therefore, it is important to know how big does recycling process in Indonesia will impact the environment. Thus, this study is conducted to analyse the environmental impact of recycling polyethylene terephthalate plastic using the life cycle assessment method. It has been found that there are two main factors causing mostly of the environmental impact from PET recycling. Those factors are due to the combustion of fossil fuel as an energy source and the poorly managed waste water and chemical residues treatment. These two factors indicate that a corrective action must be made in order to produce minimum amount of environmental impact. Hence, improvement of the recycling process can start with mitigating these two factors."
