Abstract

This study aims to determine the concentration of GA3 and the addition of sugar to the freshness of cut tuberose flowers. The research was conducted from May to June 2020, in Wano Village, Japara District, Kuningan Regency. The research method used was a Completely Randomized Factorial Design. The treatment consisted of 2 experimental factors, the concentration of GA3 with 4 treatment levels G0 (0 mg/l), G1 (50 mg/l), G2 (100 mg/l), and G3 (150 mg/l) with sugar concentration 4 treatment levels S0 (0 g/l), S1 (25 g/l), S2 (50 g/l), and S3 (75 g/l). Observations made were the decrease in fresh flower weight, number of blooming flowers, wilting period of flowers, total solution absorbed, and flower freshness period. The results showed that no interaction between GA3 and sugar treatments in all observation components. The GA3 treatment had no effect on all components of the observation, but the addition of sugar affected the reduction in fresh weight, wilting time of flowers, total solution absorbed and flower freshness. Treatment S3 (sugar 75 g/l) had the best results at a wilting period of 6.96 days, a total of 16.42 ml of absorbed solution, and a freshness period of 11.25 days.

Abstract

ABSTRACT This research aims to find out the actors in the shallot supply chain, as well as finding the best scenario in the shallot supply chain in Cirebon Regency, in increasing the supply of shallots to meet consumer demand for shallots. To obtain data for analysis, this research uses a survey method by collecting data from each component in the shallot supply chain, as well as documentation studies that are relevant to the research objectives by collecting data from related agencies or institutions. The results of the research show that: (1) Actors or actors in the shallot supply chain in Cirebon district, West Java consist of producer farmers, collecting traders (middlemen), wholesalers, retailers and consumers, (2) The dynamic system of the shallot supply chain in Cirebon district, West Java consisting of a production subsystem, supply and delivery subsystem, and demand subsystem, and (3) Model simulation to be able to project the condition of the shallot supply chain in the next 10 years using scenarios of changes to the parameters of the percentage of shallots that are scattered and increasing shallot productivity

Abstract

Pembelajaran kewirausahaan di tingkat sekolah menengah sering kali menghadapi tantangan dalam mengembangkan kreativitas dan inovasi siswa. Studi ini bertujuan untuk mengeksplorasi pemanfaatan pendekatan Design Thinking sebagai strategi inovatif dalam meningkatkan kualitas pembelajaran kewirausahaan di SMAN 3 Cikampek. Metode penelitian menggunakan pendekatan kualitatif deskriptif dengan partisipasi siswa kelas XI yang mengikuti mata pelajaran kewirausahaan. Hasil penelitian menunjukkan bahwa penerapan Design Thinking yang terdiri dari lima tahap: empathize, define, ideate, prototype, dan test, dapat meningkatkan keterlibatan siswa, mendorong kolaborasi, serta menghasilkan solusi bisnis yang lebih kreatif. Strategi ini terbukti relevan untuk menanamkan mindset wirausaha sejak dini dan meningkatkan kemampuan problem solving siswa

Abstract

Isu perubahan iklim telah menjadi pertimbangan penting di Indonesia karena adanya kompromi antara pembangunan ekonomi dan perlindungan lingkungan. Akan tetapi, penelitian yang menggabungkan aspek lingkungan ke dalam model ekonomi masih terbatas. Penelitian ini bertujuan untuk mengembangkan Tabel Input-Output Lingkungan (EE-IOT) dan menentukan sektor-sektor unggulan dalam ekonomi Indonesia dengan mempertimbangkan emisi gas rumah kaca sebagai tekanan lingkungan. EE-IOT dibangun dalam bentuk model I-O Wilayah Tunggal. Hasil penelitian menunjukkan bahwa sebagian besar emisi CO2 langsung dihasilkan oleh sektor-sektor produktif dan sisanya berasal dari konsumsi rumah tangga. Berdasarkan analisis sektor unggulan, sektor Manufaktur Produk Makanan dan Minuman menjadi sektor unggulan dengan emisi CO2 rendah. Selain itu, sektor dengan pengganda output tertinggi dan pengganda CO2 relatif rendah adalah Jasa Makanan dan Minuman. Sementara itu, Peternakan memiliki pengganda CO2 terendah dan pengganda output yang tinggi. Namun, perkembangan sektor unggulan ini tidak dapat berdiri sendiri, melainkan memiliki keterkaitan dengan sektor-sektor lain dalam hal input dan output karena sektor-sektor pendukung ini juga akan menghasilkan emisi CO2. Oleh karena itu, dengan pendekatan rendah emisi, pemerintah perlu melakukan upaya tambahan untuk mendorong sektor-sektor pendukung ini, seperti sektor energi, transportasi, pertanian, dan kehutanan.

Abstract

Eggplant (Solanum melongena L.) is an important horticultural crop in Indonesia; however, its productivity is frequently constrained by thrips infestation (Thrips palmi). This study aimed to evaluate the effectiveness of combinations of insecticide active ingredients and Ronstick surfactant in reducing the intensity of T. palmi attacks on eggplant plants. The research was conducted in Ender Village, Pangenan District, Cirebon Regency, from May to August 2025 using a Randomized Block Design with seven treatments and three replications. Treatments consisted of abamectin, dinotefuran, and their combinations, each applied with Ronstick surfactant at concentrations of 1–2 ml/L, and a control without insecticide. The results showed that insecticide–surfactant combinations significantly reduced thrips population and attack intensity compared to the control. The combination of abamectin + dinotefuran with surfactant at 2 ml/L was the most effective treatment. These findings indicate that appropriate insecticide–surfactant combinations can enhance thrips control efficiency while supporting more rational insecticide use.

Abstract

Eggplant (Solanum melongena L.) is a vegetable that is quite popular among various groups in Indonesia. Eggplant production in Indonesia in 2023 reached 699,896 tons and decreased to 675,397 tons in 2024 (BPS, 2025). With this level of productivity, eggplant plants are more susceptible to pests, one of which is Thrips. Thrips palmi usually attacks the leaves, flowers, and fruit. Damage caused by Thrips attacks on eggplant plants is characterized by silvery spots and physiological disorders on the leaves, leading to the growth of fungi that spread disease. This study was conducted in Nanggela Village, Mandirancan District, Kuningan Regency, at an altitude of ±200-300 m above sea level with a tropical climate ranging from 24°C to 33°C and an average temperature of 28°C. This study used a randomized block design (RBD) consisting of types of plant-based pesticides and their concentrations, namely clove leaf extract, garlic extract, and lemongrass extract, each of which had concentrations of 50ml/L water, 100ml/L water, and 150ml/L water. The results of the experiment showed that plant-based pesticides from garlic extract with a concentration of 100 ml/L of water had a significant effect on the intensity of attacks and damage caused by thrips, plant height, number of leaves, and crop yield in eggplant plants.
