Abstract

The glycerol residue from biodiesel production contains a lot of residue that makes it a low commercial value product with limited applications, so the glycerol residue is usually disposed of as waste in landfills. Therefore, this study aims to purify glycerol from palm biodiesel production by-products using an extraction-adsorption method. The first stage of the research was purification using petroleum ether and toluene extraction methods, followed by the adsorption stage using adsorbent in the form of activated carbon from nipah fruit waste which has an iodine adsorbing capacity of 966.978 ± 31.9433 mg/g and carbon surface area of 1066.3853 ± 35.2271 m2/g. Based on the results of FTIR testing, glycerol with adsorbent in the form of nipah fruit waste activated carbon characteristics are in accordance with commercial glycerol and the results of previous research, where the peak of O-H group is clearly formed at 3433.271 cm-1 and the peak of C-H group at 2934.672 cm-1. Based on the test results, the density value of the glycerol sample with nipah fruit waste activated carbon adsorbent was obtained with an average value of 1.255 ± 0.007 g/cm3 which was in accordance with British Standard (BS) 2621: 1979 of 1.2671 g/cm3. The test results obtained the value of the water content of the glycerol sample with nipah fruit waste activated carbon adsorbent with an average value of 8.563 ± 0.768% which is in accordance with British Standard (BS) 2621: 1979 of < 10%. The test results obtained the value of glycerol content of glycerol samples with activated carbon adsorbent of nipah fruit waste with an average value of 93.922 ± 2.523E0%.

Abstract

Tobacco (Nicotiana tabaccum L.) is an agricultural commodity in Indonesia, with production reaching 261.40 thousand tonnes in 2020.  Tobacco leaves contain flavonoids and alkaloids, which are helpful as antibacterial, antifungal, and anti-insect agents. This study aimed to optimize the extraction process of tobacco leaves as an antibacterial agent. The factors used were material-to-solvent ratio (w/v) and extraction time. The microwave-assisted extraction (MAE) was used, with the response surface methodology (RSM) for data processing. This study showed that  thematerial-to-solvent ratio and extraction time significantly affected the total flavonoid value, the extract inhibitory activity against S. mutans bacteria, and the extract yield. However, no significant effect was observed on the extract’s pH. The highest total flavonoid value, inhibitory activity, and pH were obtained from the treatment with a ratio of 1:2172 (w/v) and 6 minutes extraction time, giving an average value of 524.67 mg EQ/g, 22.4 mm, and 5.6, respectively. The highest yield of 4.61% was obtained from the treatment with a ratio of 1:5 (w/v) and 6 minutes extraction time. The optimal solution for the tobacco leaves extraction process was obtained from material-to-solvent ratio of  1: 2.6 (w/v) and 7 minutes of extraction time, giving the total flavonoids, inhibitory activity, pH, and yield of 428.4 mg EQ/g, 20.7 mm, 5.8, and 3.1%, respectively.

Abstract

A performance evaluation system for the coffee supply chain is essential to ensure the sustainability of the coffee industry in the Malang Raya region. This study aimed to design a performance measurement system focusing on the social dimension of the coffee supply chain in Malang Raya, to assess the performance score of each indicator and provide improvement recommendations. The performance evaluation applies the Supply Chain Operations Reference (SCOR) model, with weighting of performance indicators using the Analytical Hierarchy Process (AHP), and normalization of values using the Snorm De Boer method. The Traffic Light System (TLS) is employed to identify priority indicators for improvement. Results from the SCOR-based assessment indicate that Karangploso farmers scored 61.03 (Average), Dampit farmers 70.01 (Good), and Wonosantri farmers 78.32 (Good). The performance score for the roastery was 67.66 (Average), while the coffee industry scored 79.53 (Good). Based on the TLS approach, improvement recommendations for farmers, roasteries, and the coffee industry include enhancing workforce training and skill development, increasing local labor absorption, developing policies to fulfill social standards, expanding strategic partnerships, and promoting the sustainability of the coffee industry through a holistic, multi-stakeholder approach.

Abstract

The coffee agroindustry in Indonesia, particularly in Malang Raya, has undergone expansion through the increased development of coffee processing industries, including waste and emissions. Various factors, including farming practices, land use, waste management, and the utilization of by-products influence the emission levels in the supply chain. A value chain analysis in supply chain management is essential to support sustainable coffee agroindustry. The complexity of the coffee value chain involves multiple stakeholders, including input providers, producers, traders, cooperatives, and exporters, emphasizing the intricate nature of the coffee chain and the need for coordinated efforts to ensure quality and sustainability. This research aims to identify emission sources in the supply chain and determine the economic impact of coffee production at the farmer level. The value chain operations reference is the method used for measuring the value chain. The calculation results indicate that the carbon emission footprint in the supply chain activities at the farmer level amounts to 22,734 kg CO2 with a unit cost of 0.75 €/kg. These values suggest that activities in the coffee value chain at the farmer level are still not environmentally friendly (intolerable region). Suggested approaches for enhancing the value chain for coffee farmers in Karangploso encompass the installation of a smart GPS system in vehicles for route optimization and fuel efficiency, and using organic fertilizers instead of chemical fertilizers to prevent water pollution, along with the adoption of an organic farming system to enhance the economic value of the harvest. The findings of this study are expected to be a reference for research on the value chain in coffee supply chain activities, and contribute to the enrichment of information related to the VCOR model

Abstract

Tobacco stems (Nicotiana tabacum L.) are abundant agricultural byproducts that are rich in bioactive compounds. Their potential remains underexploited due to limitations in current processing and extraction technologies. This study aimed to identify superior tobacco varieties and optimize Ultrasound-Assisted Extraction (UAE) conditions for total phenolic content (TPC), Total flavonoid content (TFC), and antioxidant activity from tobacco stems. The research was conducted in two sequential stages: (1) Preliminary study for screening of TPC  and antioxidant activity of varieties Paiton 4 and Gagang Rejeb Sidi; (2) Experimental set-up using a Randomized Complete Block (RCB) Design was employed, on the selected superior variety, arranged in a factorial with three replications, factors of temperature (i.e., 40, 50, and 60 °C) and  extraction time (i.e., 30, 45, and 60 minutes). Preliminary results showed the superiority of Paiton 4, with TPC of 568.09 mg GAE/100 g and the highest antioxidant activity (IC50 of 1286.86 ppm). These results revealed that the best selected treatment achieved at a temperature of 40 °C for 60 minutes, producing the highest TPC (195.64 mg GAE/100 g) and the strongest antioxidant activity (141.87 µg AAE/g). This proved the effectiveness of low-temperature UAE in protecting heat-sensitive compounds, although the highest Total Flavonoid Content was obtained at 45 minutes.

Abstract

Nicotine is the primary alkaloid in tobacco (Nicotiana tabacum L.), playing a significant role in determining tobacco quality. The Madura variety (Prancak 95) is highly adaptable to dryland conditions, making it suitable for studying the dynamics and rate of nicotine formation at different growth stages and leaf positions. This study aimed to measure nicotine content in Madura tobacco leaves based on plant age and leaf position and to determine its formation rate between growth phases. The experiment employed a randomized block design (RBD) with a factorial pattern, comprising plant age (i.e., 25, 40, 55, 70, and 85 days after transplanting/DAT) and leaf position (i.e., lower, middle, and upper) in three replications. Nicotine content was analyzed using the acidimetric titration method (SNI 01-7134-2006), and the formation rate was calculated as the difference in nicotine content between growth stages divided by the time interval. Results showed that nicotine content increased from 1.24% (25 DAT) to 2.72% (85 DAT). Average nicotine contents were 2.43% (upper), 1.86% (middle), and 1.64% (lower leaves). At 85 DAT, the upper leaves contained about 43% more nicotine than that of the lower leaves. The highest rate of nicotine formation occurred at 70–85 DAT.

Abstract

Indonesia’s cocoa sector faces challenges in greenhouse gas emissions and smallholder income volatility. This study develops a system dynamics model to simulate the interrelationship between carbon emissions and economic performance across the cocoa value chain, identify leverage points, and evaluate alternative policy scenarios. The model integrates environmental and economic variables into dynamic feedback structures, enabling scenario-based assessment of intervention strategies. Five scenarios were simulated: composting cocoa waste increased farmer income by 2% and reduced farm-level emissions from 0.43 to 0.303 kg CO₂-eq/kg (29.79% total reduction); biogas conversion raised income by 13.56% and reduced emissions by 11%; converting cocoa waste into animal feed slightly increased income by 0.23% while cutting emissions by 58.6%; combining composting with improved transport efficiency reduced emissions by 14%; and integrating composting, logistics optimization, and government-supported input subsidies yielded the highest performance, with a 13.50% income increase and a 70% emission reduction. These results demonstrate that integrated, system-based interventions can enhance both economic resilience and environmental sustainability. The system dynamics model provides policymakers and supply chain actors with actionable insights for designing effective, climate-aligned strategies in Indonesia’s cocoa industry.

Abstract

Klorida merupakan salah satu komponen kimia yang memengaruhi mutu daun tembakau, terutama sifat pembakaran dan keseragaman kualitas hasil panen pada budidaya lahan kering. Penelitian ini bertujuan menganalisis distribusi klorida pada daun tembakau madura varietas Prancak 95 berdasarkan umur tanaman dan posisi kanopi. Percobaan disusun menggunakan Rancangan Acak Lengkap pola faktorial dengan dua faktor, yaitu umur tanaman 25, 40, 55, 70, dan 85 hari setelah tanam serta posisi daun pada kanopi bawah, tengah, dan atas, masing-masing dengan tiga ulangan. Sampel daun dikeringkan, diabukan kering dengan penambahan CaO, kemudian kandungan klorida ditetapkan menggunakan titrasi argentometri dan dinyatakan dalam mg g-1 bahan kering. Laju perubahan konsentrasi klorida antarwaktu juga dihitung untuk menggambarkan dinamika akumulasi selama pertumbuhan. Hasil penelitian menunjukkan bahwa rerata kandungan klorida cenderung menurun seiring bertambahnya umur tanaman, dari 0,96 menjadi 0,72 mg g-1 bahan kering. Namun demikian, pola distribusi vertikal dalam tajuk tampak lebih konsisten, dengan daun bawah selalu memiliki kandungan klorida tertinggi, diikuti daun tengah dan daun atas. Laju perubahan yang umumnya bernilai negatif menunjukkan adanya pengenceran konsentrasi selama pertumbuhan. Hasil ini menegaskan bahwa posisi kanopi merupakan faktor utama yang menentukan heterogenitas klorida daun, sehingga panen dan sortasi berdasarkan posisi daun berpotensi mendukung keseragaman mutu tembakau.
