Public Speaking Training In An English Community Pilot Program In Metro City, Lampung

Everyone who is capable and able to communicate, however, is not necessarily skilled at speaking in public. This limitation occasionally leads to communication misunderstandings. The IAIN Metro Community Service Team studied the English Training and Gathering (Estage) Language Education Institute, which implements the English system in a Metro City - Lampung area as a forum for improving the speaking skills and quality of members from elementary to advanced classes, supported by gathering activities that encourage students to dare to speak in public. The service training activities were given to helpg students at the English Village Estage understanding the elements and processes of public speaking. Participant skills in public speaking, such as the ability to think on the go, develop vocals to have a microphonic voice, and get used to speaking without primarily relying on text, some participants were found need ongoing preparation and adaptation to public speaking. The main ways of becoming prepared for public speaking were to help the participants develop courage and self-confidence, as well as to increase their knowledge and comprehension by continually practicing.

It can be said that the level of decentralization does not affect managerial performance in the company. The reason is because PT. Lampung Area Pegadaian does not implement a policy of granting low management authority or delegation in decision making, such as budget planning and allocation, managerial decision making, developing innovative ideas, considering large investments, and improving work quality

CG (Cloud-To-Ground) Lightning Strike Distribution Patterns In Bandar Lampung and South Lampung in 2022

This study aims to identify patterns in the distribution of CG-type lightning strikes in the regions of Bandar Lampung and South Lampung during the year 2022. This study employs quantitative descriptive research methods. The data for this study was collected from the BMKG office of North Lampung Class III Geophysical Station, located in Lampung Province. The data includes latitude, longitude, and CG-type lightning data for 2022. The sensor was positioned at coordinates 4.83° S latitude and 104.87° E longitude, with an elevation of 60 meters. It utilized the Boltek Lightning Detection System for lightning detection. The analysis indicated that the patterns of CG-type lightning strikes in Lampung Province in 2022 varied every month. This variation can be attributed to the specific topographic conditions of different areas. The Bandar Lampung and South Lampung areas experienced a significant number of lightning strikes in the year 2022. In Bandar Lampung, there were 28,502 lightning strikes, including CG+ and CG- lightning. Meanwhile, the South Lampung area recorded more lightning strikes, totaling 191,353 occurrences. The high frequency of lightning strikes in the South Lampung region can be attributed to its topography, close to Panjang and Bakauheni Harbors. These areas have many coastal regions that contribute to cloud formation, thereby increasing the likelihood of lightning. Cumulonimbus clouds are formed through the evaporation of water from sources, such as the sea, lakes, or rivers, in line with the established theory of cloud formation. Additional research is required to analyze weather data about parameters that specifically impact the frequency of lightning strikes in different regions.

Variety of Indigenous Education in the Lampung Region during the Colonization Period

This article discusses the variety of indigenous education in the Lampung Region during the Colonization Period. This study aims to reconstruct past events related to indigenous education in the Lampung Region during colonization. The results of the study show that the application of ethical politics had an impact on people's lives during the colonization period. Lampung, as one of the first colonization destinations in 1905, led to the relocation of 155 families. In the early period before the arrival of the colonists from Java, the people of Lampung had implemented a concept of education in the family with inheritance carried out by parents to their children and grandchildren. The entry of Hindu-Buddhist and Islam influenced them. The variety and education system in the Javanese and Lampung colonists experienced significant developments with the emergence of the Ethical Policy policy initiated by Van Deventer. Indigenous people's education in the Colonization area of Lampung was only obtained from First Class Schools (De Scholen der Ferste Klasse), which later developed into HIS, Second Class Schools (De Scholen Der Tweede Klasse), and Village Schools (Desaschool), or People's Schools (Volkschool) and Schools. Agricultural vocational (Landbouwsclfool or Cultuurschool) Lampung does not have ELS, Europesche Lagera School, HCS, Hollands Chinese School, or Shcakel School types of schools. Meeting the needs of secondary and vocational education is only obtained from schools in Java, Palembang, or West Sumatra because, in Lampung, there are no schools such as MULO, AMS, HBS, or Higher Education in the Dutch colonial period.

Pemanfaatan Limbah Kulit Kakao Sebagai Bahan Pembuat Pori Pada Ecopavings Block

During 2018-2019 there were floods in the Bandar Lampung area. In general, the flood that occurs is only inundation with a maximum height of 2 meters. Therefore, every residential area or roadside must have water catchment areas such as a stretch of land in the form of planting or sidewalks that have pores such as paving blocks that can absorb rainwater into the ground. Making paving blocks in this study used cocoa shell waste because it was indicated that it could be processed into charcoal which contains a lot of carbon which can absorb water, with this composition absorbing water between eco-pavings blocks. The purpose of this research is to utilize cocoa shell waste to manufacture eco-paving blocks and to analyze the physical characteristics of cocoa shell eco-paving blocks. The effect of cocoa shell waste on Eco-Paving Blocks in this study is that the more cocoa shell waste fiber is used, the more porous cavities in the eco-paving block will be, and vice versa. The paving block of cocoa shell waste produced in this study has an average density test value of 1670.751 kg/m3 to 1929.642 kg/m3. The water absorption test obtained an average value of 11.18% - 19.82%. For the infiltration test, the largest value was obtained, namely in treatment 1, which was 0.355 mm/s. The visible test is obtained with the shape of the appropriate paving texture obtained on the P2 factor because the resulting texture is good and there are no gaps or defects when the paving has been printed. Meanwhile, in the compressive strength test, the average value decreased significantly from the P1 variation to the P4 variation. The highest value was in treatment P1 with a value of 0.0154 MPA, while the lowest value occurred in treatment P4 with a value of 0.0030 MPA. However, in this study there were several parameters that did not meet the criteria for quality standard paving D. Keywords: Eco-Paving Block, Cocoa Shell Waste

The Relationship Between Brand-Minded Lifestyles and Reference Groups with Intentions to Buy Cosmetic Products in Working Women

The emergence of cosmetic products is growing with time, technology, and lifestyle. Its impact can be easily found in women as the main sales target who have a tendency to have a brand-oriented lifestyle, otherwise known as brand minded lifestyles. Individuals who have these lifestyles are only oriented to buying and using well-known, expensive and exclusive branded products. This buying behavior is also entangled with the existence of a reference group that acts as a reference point in forming beliefs, attitudes and behavior. This study aims to determine the relationship between brand-minded style and reference groups with the intention of buying cosmetic products among working women. The population is women who work at PT Amaan Indonesia Sejahtera South Lampung Area, amounting to 45 people with a total sampling technique.

The role of social forestry in achieving NDC targets: Study cases of Lampung and DI Yogyakarta

Social Forestry (SF) in Indonesia has emerged as a keystone strategy for Sustainable Forest Management. By allocating 12.7 million ha of forest to be managed by local communities, the government has set in motion an ambitious plan for SF to reduce poverty, empower local people, and improve forest conditions. More recently, SF is framed for its opportunity to contribute to climate change mitigation and adaptation. This study focused on examining the contribution of SF to the Nationally Determined Contribution (NDC) goals in Yogyakarta and Lampung. By analyzing spatial data of SF areas and land cover changes using ArcView 10.8, the study assessed the carbon stock potential in SF areas. Carbon stock calculations were based on the 2022 National Forest Reference Level (FRL) for the periods before and after SF implementation. The finding of the study indicated that the carbon stock of SF areas in Yogyakarta and Lampung ranged from 9,214,381 to 9,923,420 ton CO2eq prior to SF, while the current carbon stock ranges from 8,703,489 to 9,393,706 ton CO2eq, representing a decrease (around 5.4%) rather than an increase. Overall, the changes in carbon stock were relatively small and localized, and the magnitude of the increase was insufficient to offset the overall decrease. To achieve the objectives of SF, such as meeting emission targets and achieving sustainable land use, it is crucial to carefully manage forest edges and fragmented forests, as they can contribute to carbon stock losses. Additionally, further studies and research are needed to improve the accuracy of carbon stock calculations, particularly for non-forest categories, which have higher uncertainty in the reference levels

Analisis Risiko pada Usaha Kecil dan Menengah

Small and Medium Enterprises (SMEs) play a significant role in the global economy by contributing to economic growth, job creation and increased innovation. However, SMEs often face unique challenges and risks, which can have a significant impact on the continuity of their operations. Therefore, risk analysis for SMEs is important to help them identify, manage and mitigate potential risks that can affect their business performance. This study aims to analyze the risks faced by SMEs, as well as to identify effective methods for managing and reducing these risks. This study also aims to provide a better understanding of the importance of risk analysis in the context of SMEs. This study uses a qualitative approach and descriptive method. The population in this study were street vendors in the Lampung area. Research data obtained through direct interviews. The results of the study show that the most common risks faced by SMEs include financial risk, operational risk, market risk, reputation risk and legal risk. In addition, this study also identified that effective methods of managing risk in SMEs include product or service diversification, efficient cash management, and sound business planning. Proper risk analysis can help SMEs identify these risks and take proactive steps to mitigate them, thus increasing the chances of their business success.

PENDAMPINGAN MEMPEROLEH SERTIFIKAT HALAL

With the end of the Covid-19 pandemic, it is hoped that the MSME sector will recover. Halal products are very important in today's society. Simultaneously, the Indonesian Ministry of Religion's Halal Product Assurance Organizing Agency (BPJPH) issued a regulation that all MSME products must be halal-certified by 2024. Halal certification is very important to ensure consumers feel safe and that what they buy does not violate Islamic rules.
 Knowledge and understanding of SMEs regarding halal certification and business registration numbers (NIB) are still relatively minimal, as indicated by the low number of SMEs with halal certification. In order to increase the number of MSME businesses, this service activity aimed at 60 MSMEs around the University of Lampung area aims to facilitate direct socialization and halal certification of MSMEs. The current halal certification authorization process uses an online system which is preceded by an understanding of halal and socialization of NIB, making it easier and helping SMEs in obtaining halal certification. From this activity, it is hoped that SMEs in Lampung Province can grow better and faster. This service activity is in collaboration with the Halal Center for Muslim Scholars of the Ministry of Religion and the women's organization Women's Empowerment of UMKM (PPUMI) Lampung.

Evaluasi Agregat Lokal Sebagai Lapisan Base Perkerasan Permeabel

Permeable pavement is a type of road pavement that allows stormwater to infiltrate through the pavement surface and the underlying base layer to reduce surface runoff. Open-graded aggregates are often used as the base layers to temporarily store water and allow the water to infiltrate slowly into the soil below the pavement or through sub-drainage. The strength of open graded material is usually less than the dense-graded materials. Therefore; the mixture of the aggregate for both base and drainage layer need to be designed carefully. In Indonesia, the criteria for aggregate as both base and drainage layer is stipulated in Bina Marga Specification. This study aims at designing an optimum mixture of local aggregate to be used as the base of permeable pavement. The mixture should fulfil the mechanical properties based on laboratory CBR value, and hydraulic properties based on storage capacity and the coefficient of permeability. Five aggregate samples of Andesite origin from South Lampung area were selected for this study. Careful laboratory test procedures were adopted to select configurations of aggregate sizes (design mix formula) that satisfies the requirements both as Aggregate A and as drainage layer. A dense graded aggregate based on the grain size distribution was prepared for design mix formula to meet the requirement as Aggregate A. Then, the fine particles passing No 40 sieve was removed to form open aggregate sample suitable as drainage layer. Both samples were tested for grain size distribution, CBR, permeability and storage capacity. Results show that the local aggregate fulfils the requirements both as base and as drainage layer with average CBR of 92%, average storage capacity of 18.32% and average permeability of 0.05 m/sec. The thickness of the permeable pavement layer could be estimated based on storage capacity and the permeability of the drainage layer.
