Abstract

This research aims to analyze the raw material inventory of sugarcane using the Economic Production Quantity (EPQ) method in the sugar production process at PT. Sinergi Gula Nusantara Mojokerto. The objectives of this study are to: (1) analyze the impact of sugarcane raw material inventory on the smoothness of sugar production, (2) determine the optimal economic inventory quantity for daily production, and (3) analyze the cost efficiency of raw material inventory in daily production at PG. Gempolkrep. The data analysis methods used in this study are descriptive analysis and the EPQ method. The results show that the smoothness of production at PG. Gempolkrep is disrupted due to unmet sugarcane raw material needs, caused by the conversion of land use, especially sugarcane farming areas in the Mojokerto region. This leads to an insufficient supply of raw materials for PG. Gempolkrep. Additionally, the EPQ calculation of production quantity shows a significant comparison with the company's policy. The production quantity based on the company's policy is still below the average daily production target of 600 tons per day, while the EPQ calculation results in a production quantity of 600-700 tons per day, which is above the target. This indicates that PG. Gempolkrep is not yet optimal in its production. Regarding production costs, the EPQ method calculation is more efficient than the production costs incurred by PG. Gempolkrep. The average production cost according to PG. Gempolkrep is Rp. 23,785,399, while the EPQ calculation shows Rp. 22,574,245, resulting in cost savings of Rp. 1,211,154. From these calculations, it can be concluded that using the EPQ method is more economical and efficient in managing production costs.

Abstract

The purpose of this study is to explore the impact of service and product quality on purchasing decisions, considering brand trust as a mediator among Kopi Sejuta Jiwa consumers in Surabaya. The approach used is quantitative with a population consisting of Kopi Sejuta Jiwa buyers in Surabaya. The research sample consisted a total of 100 respondents were chosen through accidental sampling. Data collection was conducted via questionnaires and subsequently analyzed using Structural Equation Modeling (SEM), including testing measurement models and structural models, and a bootstrapping process using SmartPLS 4.0 software. Based on the results of data analysis, this study found that good service makes consumers more likely to buy a product. Product quality also influences purchasing decisions. In addition, satisfactory service increases consumer trust in the brand. Brand trust significantly influences purchasing decisions and functions as a mediator in the relationship connecting service quality with purchasing behavior, while product quality does not significantly influence brand trust, and brand trust does not play a mediating role between product quality and purchasing decisions. The results of the study also indicate that product quality and service quality have a significant impact on brand trust and purchase decisions. The coefficient of determination (R²) indicates that the model explains 43% of the variation in brand trust and 69% of the variation in purchase decisions. These findings indicate that factors beyond brand trust influence purchasing decisions at Kopi Sejuta Jiwa Surabaya

Abstract

The rapid growth of the coffee shop industry in Indonesia has intensified competition among coffee shop brands, encouraging companies to strengthen repurchase decisions through product differentiation, pricing strategies, and brand trust. This study aims to analyze the role of brand trust in mediating the effect of product differentiation and price on repurchase decision at Kopi Kenangan Surabaya. This study employed a quantitative approach using Structural Equation Modeling – Partial Least Squares (SEM-PLS) with WarpPLS 8.0. The respondents consisted of 200 actual customers of Kopi Kenangan in Surabaya selected using purposive sampling techniques from Kopi Kenangan Merr, Ahmad Yani, BP Margorejo, and The Square outlets. The results indicate that product differentiation significantly affects repurchase decision (β = 0.120) and brand trust (β = 0.650), while price significantly affects brand trust (β = 0.660) but does not significantly affect repurchase decision directly (β = 0.100). Furthermore, brand trust significantly affects repurchase decision (β = 0.820) and mediates the relationship between product differentiation, price, and repurchase decision. These findings indicate that consumers consider brand trust before making long-term repurchase decisions toward coffee shop products.

Abstract

Produk kehutanan berupa decking (HS 4418) merupakan salah satu produk ekspor kayu olahan Indonesia yang penting dan memiliki nilai ekspor yang besar di pasar internasional. Namun, industri kehutanan sangat sensitif terhadap aspek hukum ekspor kayu ke Uni Eropa. Hal ini telah menjadi urgensi global dalam regulasi kehutanan. Studi ini menganalisis pengaruh European Union Timber Regulation (EUTR) terhadap ekspor kayu decking Indonesia ke pasar Uni Eropa. Studi ini menggunakan data panel dari lima negara tujuan utama: Belgia, Prancis, Jerman, Italia, dan Belanda, yang mencakup periode 2005-2024. Metode analisis yang digunakan adalah regresi data panel. Pemilihan model terbaik dilakukan melalui uji Chow, uji Hausman, dan uji Lagrange Multiplier, dengan estimasi akhir menggunakan Random Effect Model (REM). Hasil estimasi menunjukkan bahwa EUTR memiliki pengaruh negatif dan signifikan terhadap nilai ekspor kayu decking Indonesia. Sebaliknya, GDP riil negara tujuan dan nilai tukar riil memiliki pengaruh positif dan signifikan, sedangkan harga ekspor memiliki pengaruh negatif dan signifikan. Hasil ini menegaskan bahwa regulasi hukum dan kondisi ekonomi negara tujuan merupakan faktor penting yang menjelaskan ekspor kayu decking Indonesia ke pasar Uni Eropa.

Abstract

Tofu agroindustry is one of the food-processing businesses that faces uncertainty in soybean raw material prices and sales fluctuations, which may affect business profitability. This study aims to analyze the application of Cost-Volume-Profit (CVP) analysis as a basis for profit planning at ALD Tofu Agroindustry in Sidoarjo. The research was conducted in April 2026 using a descriptive quantitative approach. Data were collected through interviews, observations, documentation, and literature review. CVP analysis was carried out by calculating the Contribution Margin (CM), Break-Even Point (BEP), Margin of Safety (MoS), Operating Leverage, and profit planning. The results indicate that the cost structure of ALD Tofu Agroindustry is dominated by variable costs, accounting for 92.8% of total production costs. The CVP analysis generated a contribution margin ratio of 21.03%, a break-even point of 5,714 molds, and a relatively high margin of safety. To achieve a target profit of 25% of sales, the company needs to increase its sales volume to 29,084 molds. These findings demonstrate that CVP analysis can serve as a basis for decision-making in profit planning and the sustainability of ALD Tofu Agroindustry in Sidoarjo.Keywords: Cost-Volume-Profit Analysis, Profit Planning, Tofu Agroindustry, Business Sustainability.

Abstract

Ekosistem mangrove perkotaan berfungsi sebagai pelindung ekologis sekaligus penghasil nilai ekonomi yang nyata bagi masyarakat. Meski demikian, integrasi empiris yang menghubungkan perilaku pasar dengan valuasi lingkungan masih jarang dilakukan. Penelitian ini menganalisis faktor penentu kunjungan wisatawan dan mengestimasi total nilai ekonomi Kebun Raya Mangrove Surabaya. Data primer dari 260 responden yang dipilih melalui quota sampling dianalisis menggunakan Exploratory Factor Analysis (EFA), Individual Travel Cost Method (ITCM), dan Contingent Valuation Method (CVM). Hasil pengujian EFA membuktikan kelayakan data dengan nilai KMO sebesar 0,79 dan Bartlett's test yang signifikan (p < 0,001), mengekstraksi enam faktor laten dengan kualitas destinasi sebagai penggerak utama. Pendekatan ITCM menghasilkan nilai guna sebesar Rp10,73 miIiar per tahun menggunakan model surplus konsumen tunggal, sedangkan CVM menghasilkan nilai keberadaan sebesar Rp8,69 miIiar per tahun melalui rata-rata kesediaan membayar (WTP) sukarela sebesar Rp150.000 per individu. Akumulasi kedua komponen menghasilkan total nilai ekonomi kawasan sebesar Rp19,42 miIiar per tahun. Temuan ini menegaskan bahwa alokasi pengelolaan yang berfokus pada kebersihan tapak dan perawatan fasilitas sangat krusial untuk menjaga utilitas lokasi, sehingga mampu mempertahankan arus kunjungan dan menjaga stabilitas nilai ekonomi ekosistem pesisir kota ini dalam jangka panjang.

Abstract

Cloves are a strategic plantation commodity that plays an important role in the economy of farmers and downstream industries. However, high logistics costs and long supply chains have the potential to reduce the profits received by farmers. This study aims to analyze the supply chain flow, logistics cost structure, and profit distribution in the clove supply chain in Wonosalam District, Jombang Regency. The research method uses a quantitative descriptive approach with the application of Activity-Based Costing (ABC). Data were obtained from 30 farmers, 6 collectors, and 3 wholesalers through interviews and field observations. The results show that logistics costs at the farmer tier are dominated by material handling activities at 82.03%, while at the collector and wholesaler tiers, they are dominated by procurement at 99.36% and 99.43%, respectively. Profit distribution in the supply chain is uneven, with farmers selling cloves at Rp105,800/kg, while wholesalers earn the highest marketing margin of Rp11,000/kg. The farmer's share value of 85.81% shows that although the supply chain is relatively efficient, the burden of logistics costs is still concentrated at the farmer level. Therefore, logistics efficiency strategies and government policy support are needed to improve the sustainability of the clove supply chain

Abstract

Kegiatan Bina Desa PKKM Agribisnis (Program Kompetisi Kampus Merdeka) 2024 yang telah dilaksanakan di Desa Kemiri, Kecamatan Puspo, Kabupaten Pasuruan mencakup berbagai program kerja, salah satunya mengenai pembuatan pakan alternatif silase. Program ini dilaksanakan pada 11 September 2024 yang bertempat di rumah Bapak Suhadi selaku ketua Kelompok Tani Sidomuncul II. Program kerja ini digagas untuk mengatasi hambatan yang dialami oleh kelompok peternak di Desa Kemiri, terutama terkait minimnya pengetahuan dalam pengolahan pakan ternak. Oleh karena itu, pemberian keterampilan dan pemahaman mengenai pembuatan pakan menjadi sangat penting, dengan tujuan memaksimalkan pengawetan nutrisi pada hijauan atau bahan pakan ternak agar dapat disimpan dalam jangka waktu yang panjang sebagai pakan ternak. Penyampaian materi dilakukan melalui metode penyuluhan yang difokuskan pada proses pembuatan silase. Hasil dari program ini menunjukkan bahwa tahapan pembuatan silase meliputi pemotongan rumput, pencacahan menggunakan alat pencacah, dan pencampuran rumput dengan bekatul secara manual. Campuran tersebut kemudian dipadatkan dalam drum fermentasi yang ditutup rapat. Proses fermentasi ini memerlukan waktu 21 hari untuk memastikan silase terfermentasi dengan sempurna.

Abstract

Chili is a strategic agribusiness commodity in Indonesia with high economic value, mainly processed products such as chili sauce. Sambal Bu Sandra is a micro-entrepreneur producing instant chili sauce and has utilized the Shopee e-commerce platform since 2016. However, amidst the increasing trend of chili sauce consumption, this brand faces challenges in optimizing digital marketing and intense competition. This study aims to formulate an optimal digital marketing strategy to improve Sambal Bu Sandra's sales performance on Shopee. The method used is a SWOT analysis, which includes the preparation of IFAS and EFAS matrices to identify strengths, weaknesses, opportunities, and threats. The analysis results show that the business is in quadrant I in the IE matrix, which reflects strong internal conditions and significant external opportunities. The resulting strategies include collaborative product development, optimization of Shopee features (such as Shopee Live and Shopee Ads), digital campaigns based on customer reviews, and adoption of a pre-order system. This study concludes that SWOT integration can provide strategic recommendations based on actual business conditions, which, if applied consistently, can potentially strengthen the brand's position in a competitive digital market.

Abstract

The objective of this study is to examine the trend of Indonesian nutmeg exports to the global market, with a particular focus on the Chinese market, and to assess the impact of macroeconomic variables, including inflation, exchange rates, and interest rates, on nutmeg exports. The data set spans the period from 1990 to 2023. The forecasting of export volume employs the ARIMA model, while the measurement of the impact of macroeconomic factors utilizes multiple linear regression. Regression analysis reveals that the inflation variable exerts no statistically significant effect on long-term export trends (p-value 0.7897 > 0.05). The exchange rate variable has a significant positive effect on nutmeg exports in the long term (p-value 0.0000 < 0.05), indicating that a depreciation of the rupiah increases nutmeg exports in the international market. The results indicate that interest rates have a significant negative effect on exports in the long term (p-value 0.0146 < 0.05). This is due to the fact that an increase in interest rates leads to an increase in production and borrowing costs, which in turn reduces export volumes. Furthermore, in the short term, none of the macroeconomic variables demonstrated a significant impact. The findings of this study indicate that the limited influence of macroeconomic factors in the short term can be attributed to the distinctive characteristics of nutmeg as a niche market commodity and the prevalence of cooperative agreements between firms. Nutmeg has essential uses and unique qualities that render its demand relatively stable and insensitive to price fluctuations or macroeconomic changes. This indicates that nutmeg, with its segmented is capable of maintaining consistent export volumes despite short-term fluctuations in economic conditions. In order to enhance competitiveness on the global market, a more focused marketing strategy and market diversification that incorporates the distinctive attributes of this commodity are essential.
