Abstract

http://dx.doi.org/10.17014/ijog.vol3no2.20085Petrographical and geochemical characteristics of the Late Oligocene Cihara Granodiorite from South Banten are presented. Data show that the rock was originated from magma of a continental origin formed at a subduction zone environment. Fractional crystallization involving plagioclase, hornblende, pyroxene, and magnetite was the main process responsible for the geochemical variation of the rocks from the Cihara Granodiorite. There are two possibilities of parental magmas to the Cihara Granodiorite, i.e. the basaltic/ or andesitic magma of the Cikotok Formation or crustal melting magma from a subduction process. Some trace element data of the basaltic rocks from the Cikotok Formation are needed to support the first interpretation. Alternatively, heating of the Jawa lower crust by magma from either mantle or subducted slab melting caused the crustal melting to produce intermediate parent magma. Some degree of mixing between those two differ- ent magma sources during the fractionation may be involved in the petrogenesis.

Abstract

Baja Menara Inti (BMI) merupakan perusahaan yang bergerak di bidang jasa yakni bengkel alat berat. PT. BMI terletak di Jl. Margomulyo No. 29, Surabaya. Banyaknya unit alat berat yang dimiliki perusahaan, mengharuskan banyaknya juga operator bengkel yang menangani pemeliharaan alat berat dan perawatan peralatan bengkel sehingga terjadi hal saling melempar tanggung jawab untuk menanganinya. Dari hal tersebut, perusahaan melakukan penyuluhan kepada seluruh operator bengkel untuk memiliki rasa tanggung jawab dan kedisiplinan. Untuk menumbuhkan sikap positif dan membiasakan disiplin diri yaitu dengan mengimplementasikan budaya 5R dengan tujuan untuk meningkatkan kualitas serta efisiensi tempat kerja. Selain budaya 5R, penulis melakukan penelitian perawatan alat kerja/ peralatan bengkel menggunakan metode FMEA (Failure Mode and Effect Analysis). FMEA adalah suatu prosedur terstruktur untuk mengidentifikasi dan mencegah sebanyak mungkin mode kegagalan (Failure Mode). Keunggulan dari metode FMEA ini dapat melakukan identifikasi perawatan peralatan bengkel yang harus diproritaskan terlebih dahulu sehingga meminimalisir terjadinya kehilangan dan kerusakan peralatan bengkel serta downtime pekerjaan yang terlalu lama. Dari penelitian yang dilakukan penulis, didapatkan hasil yaitu nilai RPN tertinggi pada data kerusakan peralatan bengkel periode bulan Juli s/d September 2023 adalah mesin gerinda terbakar sehingga dapat menimbulkan risiko kecelakaan kerja, pekerjaan terhambat, perusahaan membeli peralatan baru. Sedangkan nilai RPN tertinggi pada data kehilangan peralatan bengkel periode bulan Juli s/d September 2023 adalah Mesin bor hilang sehingga dapat menimbulkan risiko pekerjaan terhambat karena divisi bengkel harus membeli peralatan tersebut agar pekerjaan dapat diselesaikan.

Abstract

Waste is a fundamental problem that occurs in almost all cities in Indonesia. The increasingly narrow land followed by high population growth has resulted in increasing waste generation, including in Surakarta City. In response to this, the Surakarta City Government built the Putri Cempo Waste Disposal Site (TPA) Waste Power Plant (PLTSa) to solve the waste problem in Surakarta City. However, the policy has not been able to solve the waste management problem completely and create environmental impacts for the surroundings. This research aims to analyze the impacts of the Putri Cempo PLTSa development policy in Surakarta City. The method used in this research is descriptive qualitative with data collection techniques through interviews, observation, documentation, and literature study. The research used Finsterbusch and Motz's Environmental Impact Evaluation Theory. The results showed that there was an environmental impact in the form of TAR in the Putri Cempo PLTSa development policy which was still within reasonable limits of environmental quality standards so that it could still be controlled by the manager. Suggestions that can be conveyed in the research are optimizing the function of waste banks through sorting household waste and utilizing organic waste into compost and briquettes at the household level.

Abstract

Foot-and-mouth disease is a severe problem that must be faced in the livestock sector. This disease has a negative impact on various aspects, especially the economy. One way to develop herbal medicinal compounds is through local Indonesian wild plants, meniran (Phyllanthus urinaria). This research aims to determine the potential of the wild plant P. urinaria as an antiviral agent for FMD using an in silico approach using molecular docking. The compounds used as ligands are flavonoid compounds in P. urinaria, namely, routine, quercetin 7-methyl ether, quercetin 3-O-β-D-glucoside, quercetin, rhamnocitrin, astragalin, and kaempferol. This study used the control drug ribavirin as a comparison. The research stage began with the preparation of the RdRp protein from the FMD virus with Discovery Studio, ligand preparation with the Lipinski druglikeness test and minimization using OpenBabel, followed by docking and visualization. The research results found that the six flavonoid compounds in P. urinaria have potential as antiviral FMD by inhibiting RdRp, with the most potent compound being quercetin (-7.9 kcal/mol). Further research is needed, including in vitro and in vivo testing, to provide confidence in the potential of this wild plant as an antiviral for FMD.

Abstract

Keselamatan dan kesehatan kerja (K3) merupakan suatu hal yang sangat penting dan wajib diterapkan oleh semua jenis pekerjaan yang dapat menimbulkan adanya potensi bahaya termasuk pada pekerjaan proyek. Adanya peraturan K3 digunakan untuk mencegah dan meminimalisir terjadinya kecelakaan kerja yang dapat mengakibatkan cidera, penyakit akibat kerja hingga kematian. Kecelakaan kerja yang terjadi dapat disebabakan oleh dua faktor yaitu kondisi lingkungan kerja yang tidak aman (Unsafe Condition) dan perilaku pekerja (Unsafe Action). PT. CPSA merupakn vendor poject yang saat ini memiliki kontrak kerjasama dalam proyek pembangunan masjid di salah satu perusahaan BUMN. Untuk meminimalisir dan mencegah terjadinya kecelakaan kerja, perusahaan menggunakan metode Job Safety Analysis (JSA) untuk mengidentifikasi potensi bahaya yang timbul akibat pekerjaan yang dilakukan. Perusahaan juga menggunakan metode HIRARC untuk menilai dan mengevaluasi potensi bahaya yang ditimbulkan yang berdampak pada pekerja dan juga perusahaan. Dari hasil penelitian terdapat 11 jenis pekerjaan dan 37 potensi bahaya yang dapat terjadi pada proyek pembangunan masjid. Kata kunci : K3, HIRARC, JSA, Proyek

Abstract

This research investigates factors that have an important impact on organizations such as work conflict and work stress. We analyzed five international journals that are relevant to understanding work conflict and work stress in various organizational contexts. The results of the analysis show that the perceived work stress, it is stated that employees experience psychological disorders and really threaten their health when they are busy working. Employees with high levels of stress in the face of excessive workloads can experience burnout and intend to stop working. Employees who experience job insecurity cannot show their true performance and cannot obtain the desired efficiency from employees because they do not see themselves permanently in their organization. However, the expected efficiency cannot be achieved because employees who have role conflicts have to fulfill more than one workload. Employees who are satisfied with their organization are able to adopt the organizational culture and develop their organizational skills such as planning and problem solving.

Abstract

The Community Health Center Management Information System (SIMPUS) is used to provide services at the Community Health Center, from patient registration to medical services. There are several regulatory inconsistencies that occur, so an evaluation using COBIT 5 is needed to evaluate the level of capability (As-Is) and draw conclusions. Therefore, in this research, an information system audit will be carried out using the COBIT 5 Framework by measuring the Capability Level (maturity) and Gap Analysis (gap level analysis). The domains used are DSS02 (managing service requests and incidents) and DSS03 (problem management) to produce recommendations for improving the information system for existing problems. The audit results in this study show that the Capability Level for the entire domain is at the Largely Achieved criteria where the DSS02 domain is worth 3.73, DSS03 is worth 3.75, which means that the overall domain results are at level 3 (established process), which means that the system has been implemented and has been implemented. running but not yet optimally and already approaching maximum and there needs to be improvements to the SIMPUS system as well as monitoring the performance of human resources and the Puskesmas operational system in the future to get maximum results. The results of the gap level (Gap Analysis) in DSS02 are 1.27 and DSS03 are 1.25
