The COVID-19 pandemic has caused people to immobilize to eat out, many industries are closed, the community’s economy is down, and many online food small and medium enterprises (SMEs) have sprung up. One of the areas affected by the COVID-19 pandemic is East Jakarta. The implementation of Sanitation Standard Operational Procedure (SSOP) in online food SMEs requires special attention during the COVID-19 pandemic. This study aims to evaluate food production facilities in online food SMEs. Direct observation using instrument from Indonesian National Agency of Drug and Food Control (BPOM) Number HK.03.1.23.04.12.2207 2012 was conducted. The survey was conducted from May to June 2021 in five sub-districts in East Jakarta, namely Duren Sawit, Matraman, Pulo Gadung, Kampung Makassar, and Cipayung.  Of the 32 SMEs observed, 50% had been established in less than one year. Most of the SMEs owners have secondary and higher education education and sell popular Street food or food.  The survey covers non-compliance in 14 elements of food production facilities. The results show minor disobedience 18.8%, major disobedience 33.3%, serious defiance 25.8%, and critical disobedience 29.9%. In conclusion, major disobedience had the highest percentage, followed by critical, serious, and minor disobedience. Further education in the application of SSOP for online food SMEs should be carried out.

Energy and exergy analysis of systems are of great importance to enhance the energy and exergy efficiency of industrial production facilities. With the energy and exergy analyses performed, the energy dependency of the production facilities and their energy consumption can be reduced, the price of the product can decrease, and the profit margin can increase. Additionally, it is ensured that the energy produced based on fossil fuels is used in a controlled way. In the present study, the analysis of energy and exergy has been performed for the production reactor unit of the Boric Acid from Colemanite. The first law of thermodynamics and ChemCAD simulation program was used for energy analysis calculations, and the calculations of exergy analysis were carried out by using the second law of thermodynamics. The total energy loss of the reactor unit and the calculated energy loss per 100 kcal input steam were calculated as 110880 kcal/h and 3.724%, and the losses of total exergy in the reactor units and the losses of exergy calculated per 100 kcal input steam were calculated as 225058.86 kcal/h and 30.095%, respectively. Exergy efficiency for the reactor unit has been determined as 3.3 %. Some suggestions were given for the reactor units of boric acid production plants to minimize system losses.

Abstract The prospects of lithium as a component of new energy are considered. Provides data on the resources of lithium mineral raw materials. Variants of the reconstruction of lithium production facilities in Russia from domestic raw materials are evaluated in order to solve the problem of import substitution. Attention is focused on the choice of objects of priority industrial development and the need to create modern technologies for processing lithium raw materials. It is shown that the restored Zabaikalsk mining and processing plant can be a reliable source of lithium when using new technological solutions for extracting lithium and associated useful components from primary ores and waste of spodumene ores.

It is obvious that COVID-19, which is one of the main agenda items of humanity, has an effect on global production facilities. It has been tried to create a roadmap for producers to overcome existing and similar crises with proactive solutions. The reflections of the global crisis on production are carefully examined in the study. The epidemic is not limited to a single country, but affects all parts of the world, leaving supply chains and manufacturers in a difficult situation. Just as the concept of the new normal for consumers has come to the fore, the necessity of adapting to the new norm by implementing certain technologies that have been emphasized in recent years is now more clearly felt for manufacturers. The pandemic process experienced and the difficulties and enablers that producers face/will face afterwards are explained in detail under the headings of human resource management, flexibility, sourcing, technology level, logistics.

The paper presents data on the problems of monitoring and diagnosing the technical conditions of critical production facilities, such as torpedo ladle cars, steel ladles. The accidents with critical production facilities, such as torpedo ladle cars, lead to losses and different types of damages in the metallurgical industry. The paper substantiates the need for a mathematical study of the operation process of the noted critical production facilities. A Markovian graph has been built that describes the states of torpedo ladle cars during their operation. A mathematical model is presented that allows determining the optimal frequency of diagnostics of torpedo ladle cars, which, in contrast to the existing approaches, take into account the procedures for preventive diagnostics of torpedo ladle cars, without taking them out of service. Dependence of the utilization coefficient on the period of diagnostics of PM350t torpedo ladle cars was developed. The results (of determining the optimal period of diagnostics for PM350t torpedo ladle cars) are demonstrated. The system for automated monitoring and diagnosing the technical conditions of torpedo ladle cars, without taking them out of service, has been developed and described.

<p>Keputusan untuk mengadopsi varietas atau teknologi baru, terutama bagi petani skala kecil,  sangat dipengaruhi oleh kepemilikan sumber daya. Tujuan penelitian ini adalah mengevaluasi pengaruh kepemilikan aset produksi petani terhadap keputusan petani menggunakan Varietas Unggul Baru (VUB) pepaya Merah Delima. Survei dilaksanakan di beberapa sentra produksi pepaya (Sumatra Barat, Riau, Jawa Timur, Jawa Tengah, dan Jawa Barat) melibatkan 46 responden terpilih yang terdiri atas 17 petani pengguna pepaya Merah Delima dan 29 petani penanam pepaya varietas lainnya. Faktor-faktor determinan penggunaan varietas dianalisis dengan menggunakan model regresi Logit dan Tobit. Ketersediaan sarana dan prasarana produksi berpengaruh signifikan terhadap keputusan petani menggunakan VUB pepaya Merah Delima. Pengaruh sarana dan prasarana produksi terhadap  probabilitas peningkatan penggunaan varietas lebih dominan dibanding pengaruh faktor-faktor lainnya. Oleh karena itu, program pengembangan VUB pepaya Merah Delima lebih lanjut disarankan perlu didukung dengan bantuan penyediaan alat semprot (sprayer) bertenaga mesin atau ditargetkan di lokasi-lokasi yang tidak terlalu bermasalah dengan tata kelola air.</p><p><strong>Keywords</strong></p><p>Adopsi; Pepaya Merah Delima; Varietas Unggul Baru</p><p><strong>Abstract</strong></p><p>The decision to adopt a new variety or technology, especially for small-scale farmers, is heavily influenced by resource ownership. The purpose of this study was to evaluate the effect of farmer production asset ownership on farmers’ decisions to use Merah Delima papaya high yielding variety (HYV). The survey was conducted in several papaya production centers (West Sumatra, Riau, East Java, Central Java, and West Java) involving 46 selected respondents consisting of 17 farmers using Merah Delima papaya and 29 farmers growing other papaya cultivars. The determinants of farmer decision were analyzed using the Logit and Tobit regression models. The results show that the availability of production facilities and infrastructure has significant effects on farmers’ decisions to use Merah Delima papaya HYV. The influence of production facilities and infrastructure on the probability of increasing the usage of Merah Delima papaya is more dominant than the influence of other factors. Therefore, it is recommended that further Merah Delima papaya HYV development program needs to be supported by the assistance of providing farmers with machine-powered sprayers or prioritized at locations that have few water/irrigation management problems.</p>

Farmer groups as a forum for organization and collaboration between members have a very important role in the life of the farming community, because all activities and problems in farming are carried out by groups simultaneously. With the existence of farmer groups, farmers can jointly solve problems which include the fulfillment of agricultural production facilities, technical production and marketing of products. Seeing this potential, farmer groups need to be fostered and empowered further in order to develop optimally. In increasing rice production, it is necessary to preserve the production environment, one of which is through the use of organic fertilizers. Various forms and materials of organic fertilizer can be applied depending on the availability at the farm location. In an effort to improve sustainable farming, The things that are applied are increasing productivity in farming activities and the use of superior seeds, the use of fertilizers, pesticides and the application of cooperation for the manufacture of fertilizers so that group members do not need to buy fertilizer. The existence of institutions/KUD in a village is very helpful for farming communities because these institutions can also take capital loans for farmers so that farmers are able to provide good production facilities, which so far farmers have only relied on outside capital, which is not certain whether they can afford it. continue to cooperate with farmer groups.
