Abstract

Land care is one of the factors that must be considered in the sustainability of coffee production. A small number of Pagaralam coffee farmers know and apply reductant herbicide in weed control. This study aims to compare the characteristics of Pagaralam coffee farmers based on the use of reductant herbicide by using two groups analysis and cluster analysis. The characteristics of the farmers studied included 17 variables on 165 respondents who were selected by purposive sampling. The variables studied include land productivity and farmers' income. Respondents were divided into 2 categories, namely users and non-users of reductant herbicide. The initial stages of data processing in the form of descriptive statistics, hypothesis testing by mean difference test, correlation between variables, Principal Component Analysis, and biplot analysis. According to the results of the two groups analysis and cluster analysis, the variables dominantly tend to characterize the similarity in comparison between the categories of non-users and users are the variables that join into one cluster, namely land area, number of trees, coffee bean production, estimated yield, total harvest, Gross income, and Net income. While the variables that dominantly characterize the dissimilarity between the two categories are the variables that form 5 separate clusters, namely the clusters of plantation productivity, respondent identity, education, tree age, and length of harvest period.

Abstract

The presence of weeds can affect the productivity of coffee plants. The use of herbicides that are not wise in controlling weeds can have a negative impact on the quality of coffee production and land. This study aims to obtain a binary logistic regression model of the use of reductant herbicides by coffee farmers in Pagaralam South Sumatera. This research involved 165 coffee farmers, consisting of 81 farmers who used reductants and 85 farmers who did not use reductants. In the results of bivariate analysis, variables that have a significant effect on the status of using reductant herbicides, do not necessarily have a significant effect on the logistic regression model. Overall prediction accuracy of the model results of the enter method and backward method are respectively 78.2% and 76.4%. The two best models obtained show that farmer age, number of trees, number of family workers, and land productivity can reduce the probability value of farmers using reductant herbicide. On the other hand, variables that can increase the opportunity value of using reductants, starting with the greatest effect, are net income, length of harvest, frequency of herbicide use, frequency of use of organic fertilizers, and age of trees. Based on the factors that affect the use of reductants, coffee farmers should set aside costs for land maintenance, including costs for environmentally friendly weed control, so that they can support the coffee plants to continue producing optimally.

Abstract

South Sumatera songket woven cloth is one of the cultural assets of South Sumatera Province which is usually used at weddings and other traditional ceremonies. One of the villages which is famous as a producer of songket cloth is a Penyandingan Village. The songket cloth industry in Penyandingan Village experienced a decline in turnover of up to 60% during the Covid-19 pandemic. This is supported by the lack of knowledge of society regarding marketing strategies and technology in marketing products. For this reason, Shopee market management training is needed for songket cloth craftsmen and the Penyandingan Village society through the Sriwijaya University Thematic Community Service team program so that the marketing of songket fabrics can reach a wide market and be able to compete with other products. The method used is the lecture method including data collection planning and implementation of activities. The research analysis uses descriptive analysis to provide a general description of the implementation of the Shopee marketplace training. After the training was carried out,  Penyandingan Village society was able to understand the material and apply it directly using the Shopee application, and could be applied on a sustainable scale so that sales of songket cloth could increase.

Abstract

The entrepreneurial spirit is one of the basics for forming the competencies of vocational school graduates.  The lack or absence of ideas and enthusiasm (mental) for vocational school students to become entrepreneurs can be due to their mindset and skills (competencies) which are still lacking. The area of activity carried out is increasing the knowledge, skills and entrepreneurial spirit of students at SMK Negeri 1 Tanjung Batu, Ogan Ilir Regency, South Sumatra, through training in using gadgets, mastering digital literacy and using social media in digital marketing, as well as improving management skills. finance (including administration) through the use of Excel. This community service activity (PPM) also introduced several examples of business ideas and provides practical simulations of business simulations carried out by students participating in the Mathematics Entrepreneurship Course I in the current semester at the same time as PPM activity. Methods for implementing activities include presentations (material transfer), questions and answers and discussions, demonstrations/practices, simulations, and implementation assistance. Training on using smartphones to create creative content on social media can increase the enthusiasm of vocational school students majoring in TKJ (Department of Computer and Network  Engineering) in getting to know the world of business, so that they can also develop their entrepreneurial spirit and become more familiar with business ideas. Apart from that, students become more familiar with using Microsoft Excel for simple calculations on business financial bookkeeping problems, so that it can motivate them to further improve their competency in using devices. The involvement of students as assistants in implementing the PPM activities of the Village Lecture Scheme is a field practice from the Mathematics Entrepreneurship Course I (in the MBKM curriculum), so that they can gain experience, information and contribute to the community outside the campus, as well as business experience.

Abstract

Weed control is an attempt to care for agricultural land that can affect coffee production. This study aims to analyze the factors that have a relationship with the use of reductant herbicide in Pagaralam coffee farmers by using simple correspondence analysis. The research data included 19 variables and 3 categories of respondents based on the use of reductant herbicide, namely non-users, new users, and users. At the initial stage, each variable was carried out a mean difference test between 2 categories of respondents. Furthermore, each variable is divided into several categories. Then, by using the independence test, the categories of each variable are associated with the category of reductant use. There are 7 factors that have a relationship with the use of reductants, namely education of respondents, age of trees, length of harvest, frequency of herbicide use, frequency of chemical fertilizers used, frequency of organic fertilizers used, and number of labour outside the family (TL). The results of the correspondence analysis plot can show differences in the characteristics of the respondent's categories according to the use of reductant herbicide. The user category is dominantly characterized by having junior high school education, tree age more than 25 years, tend not to use organic fertilizer, and the harvest period can reach 3 months.

Abstract

Indonesia merupakan negara dengan jumlah penduduk terbesar keempat di dunia setelah India, Tiongkok, dan Amerika Serikat. Kondisi ini menimbulkan berbagai tantangan dalam pengelolaan sumber daya dan pembangunan nasional, terutama dalam pemerataan akses pendidikan, kesehatan, dan kesejahteraan masyarakat di suatu wilayah. Penelitian ini bertujuan untuk membandingkan indikator kependudukan di Indonesia tahun 2020, 2023, dan 2024. Matriks data indikator tersebut meliputi angka kelahiran, angka kematian, jumlah penduduk, laju pertumbuhan penduduk, kepadatan penduduk, dan rasio jenis kelamin yang menggambarkan kondisi sosial ekonomi, serta komponen Indeks Pembangunan Manusia (IPM) yaitu Umur Harapan Hidup (UHH), Harapan Lama Sekolah (HLS), dan Rata-rata Lama Sekolah (RLS) pada 34 provinsi di Indonesia. Reperesentasi matriks data dilakukan secara grafis menggunakan analisis biplot. Konfigurasi titik hasil biplot kemudian dibandingkan menggunakan analisis Procustes melalui dua perbandingan, yaitu 2020 dengan 2024 dan 2023 dengan 2024. Hasil biplot menunjukkan bahwa angka kelahiran hidup, angka kematian bayi dan balita, angka kematian ibu, dan jumlah penduduk berkorelasi positif tinggi. Berdasarkan analisis Procrustes diperoleh ukuran kemiripan antara kedua matriks data yang dibandingkan. Pada perbandingan pertama, nilai translasi sebesar 0,0730, nilai rotasi sebesar 0,0690, dan nilai dilatasi sebesar 0,0688 dengan ukuran kemiripan 96,05%. Sedangkan pada perbandingan kedua, nilai translasi sebesar 0,0260, nilai rotasi sebesar 0,0122, dan nilai dilatasi sebesar 0,0119 dengan ukuran kemiripan 99,29%. Hasil ini menunjukkan bahwa biplot indikator kependudukan tahun 2020, 2023, dan 2024 memiliki kemiripan, dengan perubahan yang jauh lebih kecil dalam satu tahun terakhir dibandingkan dengan perubahan selama empat tahun sebelumnya.
