POPULATION PARAMETERS OF BLUE SWIMMING CRAB PORTUNUS PELAGICUS IN THE TIWORO STRAIT, SOUTHEAST SULAWESI

The blue swimming crab (Portunus pelagicus) has a wide distribution in the fishing ground waters for fishermen's activity in the Tiworo Strait. The coastal area of Tiworo Strait has quite a lot of crab potential. Therefore, it is used as one of the pilot locations for sustainable crab management projects of the Indonesian Blue Swimming Crab Association (APRI). Growth, total mortality, natural death, fishing mortality, and the exploitation rate were the population parameters of crabs that need to be known so that management can be carried out in a sustainable manner of fisheries. A study on the population parameters of crabs has been conducted in the Tiworo Strait, based on carapace width frequencies data collected from Juli to December 2021 and analyzed using FISAT (FAO-Iclarm Stock Assessment Tool) II. The total sample is 7,809 samples, where the number of male blue swimming crabs is 3,295 samples and 4,514 females. The average size of the blue swimming crab carapace width caught was 107.57 mm for males and 110.65 mm for females. The results of the study showed that the growth rate (K) was 1.01/year, the total mortality rate (Z) was 0.67/year, the natural death rate (M) was 1.25/year, and the fishing mortality rate was 0.58/year. The exploitation rate (E) of blue swimming crab was 0.86, which showed symptoms of over–exploitation, so the management of crabs in these waters must be carried out more carefully to sustain the availability of crab resource stocks.

Comparative Investigation of Performance Analysis & Carbon Emission of Biodiesel and Conventional Fuel

In recent years, the world's largest democracies have recognized the threat posed by vehicle pollutants to our ecosystem, particularly the emission of hazardous gases. As a result, they have taken steps to tighten emission standards for motor vehicles in order to reduce toxicity. Additionally, the rapid urbanization taking place worldwide has led to increased consumption of petroleum products, such as diesel and petrol, which are derived from crude oil. Unfortunately, the reserves of crude oil are limited, and the availability of natural gas stocks is also restricted. Therefore, it is crucial to explore alternative sources of energy. This study focuses on examining the effects of using biodiesel as an additive in diesel engines (D.E) to observe its impact on various performance parameters such as noise emissions, break thermal efficiency, fuel consumption, carbon monoxide, and carbon dioxide. By comparing the effects of biodiesel blended fuels with conventional diesel fuel, we can analyze the behavior of diesel engines. The result shows the study indicate that the use of biodiesel as an additive reduces noise emission levels compared to diesel fuel. Additionally, the analysis of carbon monoxide and carbon dioxide emissions shows that biodiesel blended fuel results in lower carbon emissions when compared to traditional diesel fuel. These findings highlight the potential of biodiesel as a more environmentally friendly alternative in the context of diesel engines.

Smart Commodities Public Distribution System using IoT

In non-modern countries like India, the approach of allocating basic local goods to plight families is a significant approach to meeting the needs of a large number of people. The ongoing public dissemination system in Allot stores necessitates manual sum evaluation and trade record maintenance. The ongoing system has a ton of issues. One example is the IOT-based shrewd public appropriation framework project, which proposes a programmed method for getting products to verified cardholders. Similar to this, an informational index keeps track of the nuances of trades. Clients should enter their ID and mystery expression to get to their record through the High level cell. They are able to see the stock availability when they are successfully endorsed in. This structure uses a Raspberry Pi as the controller and uses a Specifics extraction-based extraordinary imprint coordinating computation, which has a higher accuracy score than previous versions. DC engines that are directly controlled by a Raspberry Pi for programmed product appropriation are used to open and close the valves. All along, one of the relatives need to enter one of a kind username and secret articulation. Right when client is supported in, he/she can see things that is open for that specific family account. The customer must provide a remarkable finger impression to the next level of confirmation in order to manage the items.

Penerapan Logika Fuzzy Mamdani Untuk Menentukan Stok Beras Di Toko Anugrah Jaya Cirendeu Berbasis Web

Abstract
 Rice is a very strategic food ingredient. Rice as a food ingredient is still a basic need, so the need for rice is greater than the need for industrial rice. Compared to other staple foods, national rice consumption is relatively large, so that it can be distributed evenly in sufficient quantities and is affordable by the community, increasing income for rice selling entrepreneurs. In every shop selling rice, of course, there are many problems. The problem that is often experienced is that the amount of availability is insufficient or out of stock. Each shop is definitely required to maintain the availability of sufficient stock so that sales in the store run smoothly, Fuzzy Mamdani is more specific, which means that this method pays more attention to the conditions in each Fuzzy area. So that Fuzzy Mamdani will produce decisions that are faster and more accurate. This study aims to help recommend ordering rice stock so that the stock is always available in sufficient quantities, so as to facilitate sales.

The Development of Web-based Sales and Inventory System for a Stationary Store

The study-case method was applied in this research at a stationery store. The problems derive from an observation of a stationary store called Andesta, a micro, small, and medium-sized enterprise (MSMEs) run by individuals who engage in stationery and document procurement. The problem is that transactions are not properly recorded, preventing the store from knowing the profits and losses incurred during a certain period. As a result, the availability of stocks coming in and out is unclear. This issue will be resolved by developing an integrated sales and inventory system. The prototype method is implemented in the system development lifecycle. The system will be constructed as soon as the design is completed and accepted by the business owner. The CodeIgniter framework and MySQL databases were used to build the system. The construction of the sales and inventory system is supposed to support stores in running their business processes more efficiently.

Housing policy in the social and economic sphere. Housing policy relationships and other specific policies

Abstrakt Housing policy aspiring to have a general social impact, subtracting from the scale of the state, like any other policy in this scope, is conducted in the European Union countries by the public sector. This sector remains a significant point of reference for this policy. The activity of the public sector in the countries of post-war Western Europe varies in intensity over time and is carried out at different spatial levels - also in relation to housing. The public sector has been subject to a tendency towards apparent self-limitation for at least the last four decades. This occurs mainly by reducing the importance of the state and its agencies in socio-economic development. Housing policy is one of the important sectoral policies of the state - including the government and local authorities - engaging public entities, political and social organizations and private entities to achieve the main and long-term goals in the area of housing, which are: creating conditions for purchasing or renting apartments by all citizens; ensuring the availability of the housing stock, i.e. implementing an appropriate scale of housing investments using primarily the market mechanism, and supporting the appropriate quality of the housing stock throughout the entire period of use of the property.

Analysis of the Relationship between Selling Price and Stock Condition of Wet Cat Food Products Using a Regression Approach at Cat Care Petshop

The Petshop business has been increasing recently. This is related to the economic capacity of the community and changes in several segments of society who are starting to buy food for their beloved pets, cats and dogs. Determining the selling price is a very important thing for Petshop business people to pay attention to in order to increase purchasing power and of course as one of the business people's strategies so that people want to buy animal needs at the Petshop. Apart from that, stock management must also be carried out well by the perpetrators so that there is no accumulation. Selling prices that are too high will cause stock buildup due to poor turnover of goods. This is proven by the influence of selling prices on stock conditions at Cat Care Petshop with a determination value of 82.6%. So Cat Care Petshop must regulate the selling price of feed so that stock availability can be controlled and does not pile up.

Stock Optimization of Naturally Curved Wood Logs on Freeform Truss Structures

This paper presents an optimization method for incorporating discarded naturally curved wood logs onto a freeform gridshell with a predefined topology. Though still little explored, the research field of reusing structural elements is experiencing increasing attention owing to its significant potential to reduce the environmental impact of building design. However, several constraints must be considered as the optimal structure depends on stock availability and the corresponding geometry and material properties of that given stock. Therefore, the focus is on determining the best configuration of stock elements considering the defined design objectives and constraints. The proposed method is a top-down approach, as the global topology of the structure is predetermined. Multi- objective optimization is conducted using the Strength Pareto Evolutionary Algorithm 2 (SPEA2) and a modified genetic algorithm with permutation encoding in the form of ordered crossover and scramble mutation. Furthermore, this paper introduces a Team-Based Repair (TBR) algorithm that increases the likelihood of each solution being valid for analysis. The performance of the optimization method is demonstrated on a curved gridshell structure, and the effect of the different design objectives and stock sizes on the final design is analyzed and discussed.

Study of Value-Added Soybean-Based Processed Products in Three Regencies of East Java Province

The soybean stock availability in Pasuruan, Jember and Banyuwangi regencies of East Java Province has experienced a very worrying development in the past few years due to decline in production by above 29 per cent. This has implications for the sustainability of the tofu and soybean cake (tempeh craft). Along with the limited availability of raw material, i.e. soybean, the production costs tend to reduce the added value. The purpose of this study was to analyse the added value, the relationship of soybean commodity stock availability and added value, the factors that influence profit, and the added value of the tofu & tempeh craft. Descriptive correlative method with survey and non-probability sampling techniques as well as data collection techniques through in-depth interviews were used for this study. For data analysis, Hayami method, Pearson Product Moment Correlation, and Cobb-Douglas Model Multiple Regression were used. The results of this study revealed that i) the average value added of tofu & tempeh products is IDR 8,608.09 per kilogram of raw materials with an added value ratio of 47.11 per cent; ii) there is a fairly strong positive relationship between the variable stock availability of raw materials and the added value of tofu & tempeh products, iii) the variable of the amount of production, and the price of production have a significant effect on the profit of the tofu & tempeh craft at the real level α1 per cent; and 4) variable amount of soybean raw material significantly influences the added value of tofu & tempeh products at the real level of 1 per cent.

Bi-level model predictive control for metro networks: Integration of timetables, passenger flows, and train speed profiles

This paper deals with the train scheduling problem for metro networks taking into account time-dependent passenger origin–destination demands and train speed profiles. The aim is to adjust train schedules online according to time-dependent passenger demands so that passenger satisfaction and operational costs are jointly optimized. An extended passenger absorption model that explicitly includes time-dependent passenger origin–destination demands is developed, where the term “absorption” refers to passengers boarding trains. Then, the passenger absorption model is extended to a bi-level framework, where passenger demands and rolling stock availability are considered at the higher level, and detailed timetables and train speed profiles are included at the lower level. A bi-level model predictive control (MPC) approach is developed for the integrated problem. The optimization problems of both levels of the bi-level MPC approach can be converted into mixed-integer linear programming (MILP) problems, which enables us to solve them with existing MILP solvers. We then show that the recursive feasibility of both the higher-level and the lower-level optimization problems can be guaranteed. In this way, we can achieve real-time train scheduling for the metro system. Numerical experiments, based on real-life data from the Beijing metro network, illustrate the effectiveness of the extended passenger absorption model and the proposed bi-level MPC approach.

Aplikasi Pengelolaan dan Pemesanan Pada Pangkalan Gas LPG 3KG Desa Purun Timur Berbasis Android

Based on observations that have been made at the Purun Timur Village 3KG LPG Gas Base, problems were found regarding the management and ordering process where the management of existing gas data has only used a simple method, namely by recording in a ledger regarding gas orders ordered by those who were purchased and Confirm back to the customer by telephone or via WhatsApp that the order has been recorded. Ordering 3KG LPG gas, the owner of the base only has 9 gas stocks available at certain hours, so he doesn't know the availability of gas stocks on a regular basis. This is certainly less effective and efficient in terms of time and effort. Therefore, an online 3KG LPG gas management and ordering application is needed that can place orders and provide information on the availability of 3KG LPG gas. The research method used is a qualitative descriptive method, while the system development method uses the RAD (Rapid application development) method.

Analisis dan Perancangan Sistem Informasi Manajemen Distribusi Barang Dagang

ANH is a business engaged in the distribution of goods with a model of selling and buying goods. The distribution process of goods sold is goods purchased from several suppliers which are then collected and resold. In the process of distributing goods, it is done manually, starting with recording requests to suppliers and customers with note media as proof of transactions. The documentation process for recording proof of transactions often results in documentation errors due to several factors, including, (1) the possibility of adding or reducing ordered products due to changes in orders and not properly documented on notes. (2) the customer contacts ANH again or vice versa to confirm stock availability in the warehouse in real time. Solving problems that occur at ANH can be solved with a good management information system by utilizing technology. The design aimed at solving the problem is to reduce errors in the documentation process by using notes that sometimes change in the field, processing records more quickly and integrated so as to reduce the risk of errors in providing information on goods in the warehouse and errors in the process of inputting purchase requests. The development method used is the iteration method. Analysis of the problems that occur in ANH uses the PIECES (Performance, Information, Economic, Control, Efficiency, Service) framework problem analysis.

Организация оказания медицинской помощи пострадавшим при чрезвычайных ситуациях в лечебных медицинских организациях Федерального медико-биологического агентства. Сообщение 2

Summary. The aim of the study is to examine and analyze the state and procedure of implementation in medical organizations (MOs) of the Federal Medical and Biological Agency (FMBA of Russia) of significant organizational measures ensuring their readiness to provide medical care to victims during the elimination of the consequences of probable emergency situations at the served objects and territories. Materials and research methods. Materials of the study were regulatory and methodological documents of FMBA of Russia, regulating the order of organization of medical care for victims in emergency situations at facilities and territories served by FMBA of Russia; scientific works and publications on the subject of the study; special examination cards of 66 MOs of FMBA of Russia, filled out by medical specialists of MOs, including medical specialists of district medical centers of FMBA of Russia — data as of December 1, 2022. The surveyed MOs, regardless of their location and taking into account their functional capabilities, were divided into 3 levels (1st, 2nd and 3rd). The main objects of the study: the activity of MOs in creating mobile medical formations and units; readiness to perform medical triage of victims in emergencies; ability to conduct telemedicine consultations; equipment of MOs with medical devices and appliances used in the provision of medical care in emergencies. Research methods were statistical, sociological (method of expert evaluation) and analytical. Results of the study and their analysis. Mobile medical units are formed mainly on the basis of MOs of the 2nd and 3rd level. The specialization of a unit is determined by the availability of appropriate medical personnel in MOs, as well as by the peculiarities of the activities of the organization served. It has been established that the main factors that complicate the formation and provision of evacuation reception center activities during liquidation of medical and sanitary consequences of an emergency are: lack of equipment and personal protective equipment (PPE), lack of experience and proper regulatory and methodological support of activities in the emergency mode, etc. It was noted that medical specialists who have no experience of working under conditions of mass simultaneous arrival of patients or victims in emergency situations should be trained at special trainings and exercises to understand tasks and conditions of medical triage. Most MOs are ready to form up to 4 teams to perform medical triage in case of mass simultaneous arrival of patients. When analyzing the data on the availability of an irreducible stock of drugs and medical equipment to provide medical care to emergency victims, it was revealed that it was created and maintained only in 70-80% of MOs of the 1st-3rd level. It is concluded that the minimum stock of drugs and medical equipment should be created and maintained in each MO of FMBA of Russia and others.

Exploring the Impact of a Housing Support Service on Hospital Discharge: A Mixed-Methods Process Evaluation in Two UK Hospital Trusts

Delayed discharge from hospital is a global healthcare problem with negative impacts on patient outcomes and the wider health system. Delays to discharge can arise when a patient remains in hospital even when they are medically fit due to nonmedical reasons such as a lack of appropriate housing or social care. However, whilst several nonmedical interventions have been developed to facilitate timely hospital discharge, there remains a lack of evidence on their impact. This study reports on findings from a mixed-methods process evaluation of a newly integrated housing and health service in two United Kingdom- (UK-) based hospitals (one mental health hospital and one general hospital). The service involved housing support coordinators (HSCs) being based within hospitals and supporting inpatients with their housing-related needs. We employed qualitative interviews with service users and hospital/housing staff (N = 16) and routine data analysis (n = 488) to understand the impact of the service and any challenges to service delivery. Service users faced different housing barriers, for example: 28.3% experienced homelessness (n = 136) whilst 80 (16.4%) faced challenges with their accommodation no longer meeting their physical needs. Service users received support for a variety of issues such as assistance with medical priority applications, support to apply for social housing, and referral to other support services. Healthcare professionals at all levels credit the service for improving hospital discharge processes and reducing stress on clinical staff, enabling them to concentrate more effectively on clinical tasks. Key to success is experienced housing staff providing patient-centred support, being integrated within a multidisciplinary team with management and oversight from the health service, and the availability of appropriate housing stock and wider services to support people after discharge. Our findings indicate that other hospitals may benefit from implementing similar housing and health integrated services.

PENGARUH PUPUK ORGANIK CAIR URINE SAPI PLUS TERHADAP PERTUMBUHAN DAN HASIL TANAMAN SELADA (Lactuca sativa L.)

Lettuce has great potential to be cultivated because it has a short harvest period, a wide open market, and a relatively stable price. The demand for lettuce also continues to increase, but the availability of lettuce stock is still limited. This causes the use of chemical fertilizers to increase. Continuous use of chemical fertilizers can damage soil fertility and the environment. One way that can be applied to support an environmentally friendly cultivation system is the use of liquid organic fertilizer plus cow urine. This liquid fertilizer is made from cow urine and additional ingredients in the form of spices and tobacco. Utilization of cow urine can help increase the economic value of livestock waste. In addition, this organic cow urine plus liquid organic fertilizer also contains nutrients that can help increase plant growth and yields. Additives such as spices and tobacco in fertilizers also help control pests on plants. The method in this study used a one-factor Randomized Block Design with p0 (0%), P1 (5%), P2 (15%), P3 (25%), P4 (35%), and P5 (45%). The results showed that liquid organic fertilizer plus cow urine had a significant effect on plant height, leaf width, number of leaves, and fresh weight of lettuce plants. The best concentration of organic cow urine plus fertilizer on the growth and yield of lettuce was found in treatment P1 (5%) with an average plant height of 9.22 cm, number of leaves of 14.75 cm, leaf width of 7.77, and fresh weight of 30.13 g.

Eucalyptus oil as adjuvant therapy for coronavirus disease 19 (covid-19): a randomized clinical trial

Link of Video Abstract: https://youtu.be/WzYiDQR2RvA Introduction: The coronavirus disease 19 (COVID-19) vaccination scheme is still being implemented worldwide, but problems with stock availability and other factors are still impeding this endeavor, especially in developing nations like Indonesia. Ethnopharmacology is known to provide a good source of a cheap candidate for anti-inflammation drugs. This study was conducted to determine the effectiveness of affordable adjuvant therapy, Eucalyptus oil, which has been used as a household remedy for respiratory tract infections in Indonesia. Methods: 52 mild-moderate COVID-19 patients were randomly assigned for a prospective clinical trial. A group of 26 patients was given standard COVID-19 treatment as a control group, while another 26 patients as the treated group were given standard therapy and use Eucalyptus oil as an adjuvant. The clinical sign and symptoms, cytokines interleukin (IL) 6, IL-10, and transforming growth factor-beta (TGF-β) profiles were recorded during the study period. Result: There was a trend of better improvement of clinical symptoms among patients who received adjuvant treatment than the control group. Altered smell (p = 0.003) and cough (p = 0.641) recovered faster in the treated group. While there was no marked difference in IL-10 and TGF-β levels among both groups, IL-6 level in the treated group was significantly lower and the neutrophil-to-lymphocyte ratio (NLR) was significantly decreased (p < .05) than the control. Conclusion: Using Eucalyptus oil as an adjuvant of COVID-19 treatment promotes faster recovery of mild-moderate COVID-19 patients, probably via inhibition of the IL-6-mediated inflammation process.
