Abstract

Cabai merah merupakan salah satu komoditas pertanian yang sering mengalami fluktuasi harga jual baik ditingkat petani maupun konsumen. Fluktuasi harga ini dianggap menjadi salah satu penyebab terjadinya inflasi di Indonesia. Penelitian ini bertujuan untuk meramalkan harga jual cabai merah di tingkat konsumen berdasarkan data penjualan cabai merah di Pasar Rakyat Kemang Perumda Pasar Tohaga Kabupaten Bogor. Pada penelitian dilakukan perbandingan dua metode peramalan kuantitatif yaitu Moving Average dan Exponential Smoothing. Hasil penelitian menunjukan bahwa metode Exponential Smoothing memiliki hasil lebih baik, dimana nilai ukuran kesalahan MAD, MAE, dan MAPE memiliki nilai yang lebih kecil dibandingkan Moving Average sehingga harga jual cabai merah di periode Januari 2022 diperkirakan sebesar Rp. 27.579,-

Abstract

Economic growth experienced a decline in the industrial sector, especially in transportation and warehousing. One way to improve distribution performance using transportation to determine the number of fleets used for delivery is by determining distribution routes that produce the shortest distance using the saving matrix method. The research results show that the optimization of the transportation mode is 2 vehicles with route savings of 27 Km for vehicle-1, and 23 Km for vehicle-2. This has an impact on Goods Delivery Service companies being able to optimize distribution costs from saving on the number of transportation modes that have been used so far from 4 vehicles to 2 vehicles.

Abstract

MSMEs are one of the important sectors to support economic growth. In the midst of increasingly tight competition, business actors need to implement effective strategies to anticipate fluctuations in market demand so that accurate demand forecasting is a crucial step to ensure optimal stock availability. Currently, MSMEs only make predictions based on instinct and experience, not based on mathematical calculations, so that sometimes there is overstock or understock of the goods produced. This study analyzes the demand for sandals and shoes at MSME Mulyaharja, Bogor City using the moving average and exponential smoothing methods. The purpose of this study is to determine the most accurate forecasting method to optimize inventory management and minimize the risk of shortages or excess stock. Historical sales data for one year is used as the basis for the analysis. The results of the comparative analysis of forecasting errors show that the Moving average method with 2 periods provides the most accurate results, with a Mean Absolute Deviation (MAD) value of 54, Mean Squared Error (MSE) of 3380, and Mean Absolute Percentage Error (MAPE) of 18%. The conclusion of this study is that the 2-period Moving average method is the best method to be applied to Mulyaharja UMKM, by applying this forecasting method, overstock and understock of product inventory can be reduced because the amount of production produced is close to the amount of customer demand.

Abstract

PT XYZ is a company engaged in the textile and garment sector. The problem that occurs is the accumulation of fabric raw materials in the warehouse due to excess inventory compared to the demand received. The purpose of this research is to determine the safety stock to prevent overstock. The research method consists of forecasting along with the parameters MAD, MSE, and MAPE as validation using POM QM software. In addition, production control is carried out using the min-max method to determine the amount of inventory required. The results of the study show that the company can use the exponential smoothing forecasting method with an alpha accuracy level of 0.7, which shows that the forecast for the next period is 6,315,349 yards with a MAD value of 1,278,671 and a MAPE value of 21.76%. Furthermore, the company can reorder (ROP) 2,721,298 yards, safety stock of 1,360,649 yards with a minimum inventory of 7,802,654 yards and a maximum inventory of 15,605,307 yards.

Abstract

This study aims to evaluate the production performance of Micro, Small, and Medium Enterprises (MSMEs) in rengginang production using the Quality Function Deployment (QFD) approach. Rengginang is a traditional Indonesian snack made from sticky rice, which has economic and cultural value but faces challenges in production consistency, hygiene, and capacity due to manual processing methods. The QFD method was applied to translate six key customer needs—such as production speed, hygiene, capacity, consistency, quality control, and product variation flexibility—into technical characteristics through the House of Quality (HoQ) matrix. Results showed that the most critical production need was achieving a drying process of no more than one day, followed by hygienic handling. These were translated into technical priorities such as high-speed drying machines and closed-drying systems. The relative weight analysis indicated that these technical improvements had a high impact on production performance with relatively moderate implementation complexity. This study provides MSME actors with a structured model to improve production efficiency and competitiveness based on customer-oriented planning. Keywords: Quality Function Deployment (QFD), House of Quality, MSMEs, Rengginang, Production Performance

Abstract

This study evaluates the effectiveness of agricultural extension activities aimed at enhancing the knowledge of farmers of composting and good agricultural practices for avocados in Mulyaharja village, Bogor, West Java Province, conducted in October 2024. A total of 10 participants completed pre- and post-tests designed to measure their understanding of avocado cultivation and composting practices. Results showed a significant increase in knowledge regarding avocado cultivation, with scores rising from 64% to 79% post-intervention (P=0.049). However, the improvement in composting knowledge was minimal, increasing from 57% to 63%, which was not statistically significant (P=0.29). These findings indicate that targeted extension activities can effectively improve knowledge related to avocado farming while suggesting a need for more engaging methods to enhance composting knowledge. This research highlights the critical role of tailored extension services in promoting sustainable agricultural practices and enhancing the capabilities of farmers in the region.

Abstract

Horticultural extension services in Bogor are instrumental in promoting agricultural development by enhancing the productivity and sustainability of local horticultural practices. This study emphasizes the empowerment of women farmer groups, known as Kelompok Wanita Tani (KWT), to improve horticultural production through targeted initiatives such as providing essential production facilities and enhancing the skills of farmers and extension officers. Data collection was conducted from July to September 2024, using questionnaires and surveys to assess the knowledge of KWT members before and after extension activities. The results indicated a significant increase in knowledge related to horticultural crop cultivation, with pre-test scores rising from 69% to 87% post-training, demonstrating a 17% improvement (P0.01). This improvement in knowledge and practices is a promising sign for the future of horticultural development. Correlation analysis revealed interesting relationships among agricultural knowledge, educational background, age, and agricultural experience. This research highlights the crucial role of extension services in disseminating knowledge and best practices, ultimately improving the livelihoods of farmers in Bogor and contributing to the local economy.

Abstract

Pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kesadaran pelaku Usaha Mikro, Kecil, dan Menengah (UMKM) sepatu di Desa Mulyaharja, Kota Bogor, terhadap penerapan budaya kerja 5R (Ringkas, Rapi, Resik, Rawat, dan Rajin) sebagai upaya peningkatan efisiensi operasional dan keberlanjutan usaha. Kegiatan ini menggunakan pendekatan partisipatif dengan metode identifikasi kebutuhan, pelatihan, serta evaluasi berbasis pre-test dan post-test. Sebanyak 15 karyawan UMKM terlibat sebagai responden, menunjukkan peningkatan signifikan dari nilai rata-rata pre-test sebesar 35 menjadi 95 pada post-test. Hasil observasi menunjukkan adanya peningkatan dalam awareness implementasi 5R di lingkungan kerja. Program ini membuktikan bahwa implementasi budaya kerja 5R dapat dilakukan secara sederhana, efektif, dan tanpa memerlukan biaya tambahan yang signifikan. Oleh karena itu, disarankan agar program serupa dilaksanakan secara berkala, didukung oleh pembentukan tim internal 5R dan pendampingan berkelanjutan dari perguruan tinggi, guna menjamin keberlanjutan implementasi serta menjadikan Mulyaharja sebagai model bagi UMKM sektor lainnya.
