Abstract

The population growth in Indonesia will lead to increased demands in the development sector.This growth must be balanced with environmentally friendly development practices. Therefore,there is a need for alternative uses of industrial waste into other finished materials. Concretebricks (Paving blocks) are one of the building construction materials that function to cover orpave the ground. Boiler ash is one of the solid wastes of the palm oil industry which comes fromthe remains of burning shells and fibers in boiler machines. Palm oil shells are also one of thesolid wastes of the palm oil industry which comes from the separation between fiber and shellswhich occurs in the Light Tenera Dust Separator machine. (LTDS). Seashells can be considereda form of solid waste. According to the research findings, paving blocks treated with S1 and S2exhibit water absorption capacities that comply with SNI 03-0691-1996 standards, whichstipulate a maximum of 8% for C grade, suitable for pedestrian use. Paving blocks treated withS3 also meet the SNI 03-0691-1996 standards, with a maximum absorption of 10% for D grade,which is ideal for covering plants and home gardens. Lower water absorption rates indicatehigher quality paving blocks. Variance analysis reveals that water absorption capacitysignificantly impacts the quality of paving blocks. The compressive strength test showed thatpaving blocks with S2 treatment had the highest strength, averaging 2.10 MPa. The highpercentage of boiler ash, which acts as a partial binder for the sand, is the reason for this. Thelowest compressive strength, averaging 1.01 MPa, is observed in paving blocks treated with S3.This is because of the significant amount of shell ash, which contains the chemical compoundsilica, similar to sand. Additionally, according to SNI 03-0691-1996, the compressive strengthtest results for paving blocks treated with S1, S2, and S3 do not meet the minimum requirementof 8.5 MPa. Analysis of variance indicates that the compressive strength of paving blocks variessignificantly.

Abstract

Robusta coffee is the most widely cultivated coffee commodity in Indonesia. In the East Bolaang Mongondow Regency, the problem at the supplier level is limited market information, which makes the coffee beans' quality inconsistent, impacting the price and product quality image. This research aims to identify supply chain structure models and members, added value, and design a traceability system to support product quality validation. Robusta coffee supply chain participants and their interactions were identified at the Modayag coffee plantation in East Bolaang Mongondow. The data were collected through observations, interviews, and field studies. Supply chain analysis was performed using the Vorst method and the added value was calculated using the Hayami method. The traceability system design follows the system development lifecycle method. The findings indicate that the Robusta coffee supply chain in East Bolaang Mongondow Regency includes farmers, collector traders, processing plants, the retail industry, coffee roasteries, and consumers. Farmers profit from selling perfectly ripe wet coffee beans 42-43%, wet mixed coffee beans (8%), and dry mixed coffee beans 63-71%. A traceability system named Kinton was successfully developed and integrated with the Firebase database to store all information.

Abstract

Mutu buah melon dapat ditingkatkan dan dioptimalkan dengan melakukan pemangkasan pada tanaman melon. Pemangkasan merupakan proses penghilangan yang dilakukan pada bagian tanaman tertentu. Saat ini tanaman melon masih dipangkas secara manual oleh petani, namun cara ini mempunyai banyak kekurangan. Pada penelitian ini pemangkasan dilakukan pada cabang dan daun tanaman melon. Pemangkasan dapat dilakukan dengan bantuan robot yang mampu mengenali daun dan dahan. Pada penelitian ini metode yang digunakan untuk mendeteksi cabang dan daun adalah Mask Region-based Convolutional Neural Network (Mask R-CNN). Teknik tuning hyperparameter digunakan untuk mendapatkan nilai parameter terbaik, termasuk learning rate, peluruhan bobot, dan momentum pembelajaran. Dua skenario dipertimbangkan dalam penelitian ini, satu dengan 10 epoch dan yang lainnya dengan 30 epoch. Nilai Average Precision (AP) yang diperoleh pada 10 epoch sebesar 32,2% untuk objek daun dan 0% untuk objek cabang. Pada 30 epoch, nilai AP adalah 56,8% untuk objek daun dan 4,1% untuk cabang. Rata-rata Presisi Rata-rata (mAP) adalah 16,1% untuk 10 epoch dan 28,4% untuk 30 epoch

Abstract

Chrysanthemum (Chrysanthemum morifolium) has high economic value. However, fresh Chrysanthemums are perishable and have a short shelf life. High respiration and microorganisms are the main causes of the decline in the quality of chrysanthemums after harvest. The fungus Puccinia horiana causes white rust disease on the leaves which were carried when the flowers are harvested and stored for distribution. Corn starch as an edible coating material combined with red galangal extract was expected to reduce damage by these two factors. The purpose of the research was to determine the best concentration of corn starch and red galangal extract to extend the shelf life of fresh chrysanthemum edible flower. The starch concentration chosen was based on the viscosity of the coating solution which can be applied by spraying and produces the solidness and smallest diameter of droplet. The concentration of 2% corn starch coating solution was chosen to be the best solution concentration for coating. In application, the coating solution used was 2% corn starch combined with 1% and 2% red galangal extract, with spraying done once and twice. The results of the study showed that the L2S2 formulation (2% galangal concentration with spraying 2 times) was the best treatment. This treatment can maintain flower water content at 86.02%, weight loss 19.00%, L value 34.50o, Hue value 347.04o on the 6th day of storage with a panelist assessment of a score of 3.25 (freshness, color, aroma). As a comparison, flowers without treatment (control) were still accepted by panelists up to the 3rd day of storage with a score of 3.01, more than 3 days the score was less than 3

Abstract

Land conversions pose a threat to food security. Urban agriculture is considered to be a solution to this issue. Urban agricultural innovations are diverse, including vertiminaponics, cube-model microirrigation, and Nonpowered Automatic Fertigation systems. The development of a powerless automatic fertigation innovation involves creating a portable Minapadi concept by substituting some components, such as pots, with fiberglass boxes. This study aims to achieve a good box design to support the concept of urban agriculture. The study began by testing 10 fiberglass samples on a UTM machine to obtain the mechanical properties of the material, such as the modulus of elasticity, which were input into a computer simulator along with other physical and mechanical properties. The computer-aided simulator used was the ANSYS 2024 R2 Student software, simulating two potential box designs: the first box had a thickness of 4 mm with a lateral support in the middle of its vertical span, while the second box had a thickness of 6 mm without lateral support. Loading was applied hydrostatically with water level heights ranging from 50 to 400 mm and thermal loading simulating solar radiation. The results of this study show that solar radiation has a minimal impact on box deformation, whereas water-level height plays a significant role in box deformation. The first box design was considered the best based on deformation due to hydrostatic pressure, with a maximum deformation of 2.175 mm under hydrostatic loading with a water level height of 400 mm.

Abstract

One of important quality parameters of white crystal cane sugar is its color, which is measured as the ICUMSA value referring to the standard method established by the International Commission for Uniform Methods of Sugar Analysis (ICUMSA). It is usually measured in a laboratory using a complex and lengthy chemical analysis method. To overcome this challenge, this research attempts to explore the potential use of multi-channel spectral sensors in the UV-Vis-NIR region as an alternative method to predict the ICUMSA value. The proposed portable device uses an AS7265X sensor as the main component. The spectra data of 60 cane sugar samples were collected using the proposed device followed by measurements of ICUMSA value in the laboratory using standard methods as reference. The prediction using partial least squares regression (PLSR) model achieved R2 = 0.896, RMSEC = 0.072%, RMSEP = 0.103%, CV = 26.087%, and RPD = 3.104. The multiple linear regression (MLR) model achieved R2 = 0.910, RMSEC = 0.067%, RMSEP = 0.111%, CV = 24.328%, and RPD = 3.328. The artificial neural network (ANN) model achieved R2 = 0.999, RMSEC = 0.004%, RMSEP = 0.037%, CV = 1.433% and RPD = 9.543. This result indicates that the developed PLSR, MLR, and ANN models can predict the ICUMSA value well with ANN as the best model. It also can be concluded that the proposed portable device can be an alternative for rapid analysis of ICUMSA value.

Abstract

The quality of sugarcane in the plantation is the most important information for farmers and sugar factories for assessing the maturity of sugarcane and determining the optimal harvest schedule. The brix value is used as a quality index in the sugar industry and is an important parameter for the evaluation of cane quality and maturity. Traditional methods of determining brix involve time-consuming and labor-intensive processes, often involving destructive sampling. To overcome these challenges, this study proposes a non-destructive approach using portable near-infrared (NIR) spectroscopy to predict the sugar content in sugarcane stalks. The main objective of this study was to develop a nondestructive prediction model for the brix value in sugarcane using portable NIR spectroscopy. Data processing involved two models: Partial Least Squares (PLS) and an Artificial Neural Network (ANN), along with various data pre-treatment techniques. The PLS model showed an improvement in prediction accuracy with data pre-treatment, especially with the Savitzky-Golay method (R2 = 0.755, RMSEP = 1.22%, RMSEP = 1.43%, CV = 6.13%, and RPD = 2.02). In addition, the ANN model combined with Principal Component Analysis (PCA) showed high predictive performance when sugarcane was 11 months old (R2 = 0.797, RMSEC = 0.56%, RMSEP = 0.87%, CV = 3.04%, and RPD = 2.96).

Abstract

Dependence on fossil fuels causes significant environmental damage and increases costs and scarcity in the future. To overcome this problem, a transition to renewable energy is needed, one of which is biodiesel which can be obtained from used cooking oil. This study aims to convert used cooking oil that cannot be reused into biodiesel products. Biodiesel synthesis can be carried out by the transesterification process, using NaOH catalyst with concentration variations of 0.5%, 0.75%, 1%, 1.25%, and 1.5% of the total mass of oil. The test parameters are calorific value, density, viscosity and flash point as well as yield on used cooking oil biodiesel products. The test results show that the use of a catalyst concentration of 1% produces more optimal density, viscosity, and calorific value and flash point. Each value is 0.859 g / cm³, 2.34 cSt, 10,356 cal / g, and 139°C. However, the use of a catalyst concentration of 0.5% shows that the biodiesel product is less than optimal. This can be shown by the highest density, viscosity and flash point values of the catalyst concentration variations used. Each value is 0.88 g/cm3, 3.16 cSt and 178°C, while the calorific value is also low with a value of 9,689 cal/g. However, when viewed from the yield, the catalyst concentration of 0.5% produces the highest value of all catalyst concentration variations used with a value of 88%.
