Abstract

Low coffee production and quality are two major problems of the Indonesian economy that must be addressed, especially in smallholder plantations. The use of Growth Regulators (ZPT) and Planting Media in coffee with the grafting method is expected to help in the growth of coffee plants. This study was designed using a Factorial Completely Randomized Design (CRD) consisting of 2 factors, namely ZPT Growtone Concentration (G0: Control, G1: 20/250 ml, G2: 25g/250 ml, G3: 30g/250 ml) and Composition of Planting Media Soil, Manure, and Sand (M0: Control, M1: 1:1:1, M2: 1:2:1, M3: 1:3:1). Each treatment was repeated three times. The parameters analyzed included plant height, number of roots, root length, root weight, stem diameter, and number of leaves. All data obtained in the study are presented in the form of tables and diagrams. The data obtained will be analyzed using analysis of variance (ANOVA). To test the effect of treatment on the observed variables, if there is a significant difference, the DMRT (Duncan Multiple Range Test) further test will be conducted at the 95% confidence level. The results showed that the combination of ZPT Growtone and Planting Media types of soil, manure, and sand had a significant effect on the number of branches parameter, and each factor also had a significant effect on the root length parameter. The best treatment is the combination of  ZPT Growtone 20g/250 ml and Planting Media Composition 1:1:1. The treatment has the highest number of branches with an average of 2.67. The effect of the two factors on the grafting cuttings seedlings on the root length parameter was 16.83 and 16.96, respectively.

Abstract

Natural resources in Indonesia are very abundant, but there are still some that are not utilised properly so that they only become waste polluting the environment, one of which is acid wood. This waste can be innovated into briquettes. This study aims to identify the characteristics of briquettes from tamarind wood and coconut shells with starch adhesive, including moisture content, ash, volatile substances, bound carbon, and calorific value. This study uses a complete randomised design (CRD) as a tool to analyse significant data at the 0.05% level. Each concentration involves a variation of composition between tamarind wood charcoal and coconut shell charcoal, with additional starch adhesive in the ratio of 90%:10%, 45%:45%:10%, and 50%:40%:10%. Each sample will then be analysed for moisture content, ash content, volatile matter content, bound carbon content, and calorific value.  The results showed that the composition of the material mixture greatly affected the characteristics of the briquettes. The lowest average value of moisture content is at concentration P1 with a value of 1.69%, the lowest value in ash content is at concentration P1 with a value of 5.06%, the lowest volatile substance content is at concentration P1 with a value of 13.34%, the highest bound carbon is at concentration P3 with a value of 29.21% and the highest calorific value is at concentration P3 with a value of 6690 cal/gram. The characteristics that meet the SNI NO. 01/6235/2000 standards are only moisture content and calorific value, with the specified standards for moisture content <8% and calorific value >5,000. So from all five testing parameters of moisture content, ash content, volatile substance content, bound carbon content and calorific value, the best treatment was treatment P1 with 90% KA concentration: 10% adhesive.

Abstract

Temulawak is a medicinal plant whose rhizome is utilised. To extend the shelf life, temulawak is processed into instant powder drink through crystallisation method with the help of sugar as sweetener and crystallisation agent. This study aims to analyse the physicochemical characteristics of temulawak instant powder produced from the crystallisation method and determine the best sugar concentration on the characteristics of the instant powder produced. This study used a completely randomised design (CRD) method with one factorial, namely different sugar concentrations (40%, 50%, and 60%). The results showed that different sugar concentrations affected the parameters of water content, degree of fineness (FM), grain average (D), redness level (a), yellowish level (b), water absorption and yield. Moisture content values ranged from 2.14 - 2.72%; FM values ranged from 1.39 - 2.05; D values ranged from 0.011 - 0.017 mm; brightness values ranged from 74.49 - 77.43; redness values ranged from 29.52 - 31.16; yellowness values ranged from 67.56 - 69.92; bulk density values ranged from 0.478 - 0.495 g/cm³; water absorption values ranged from 7.74 - 9.01% and yield values ranged from 36.07 - 50.99%. The best formulation of different sugar concentrations is the treatment formulation with 40% sugar concentration.

Abstract

Demand for melinjo chips is high, but the current production method is less efficient in terms of time. The melinjo flattening machine is a new innovation that has the potential to replace the conventional process, thus optimising post-harvest handling. It is expected that the use of this flattening machine can increase work capacity and facilitate the production of quality melinjo flattening products in the future. This study used experimental methodology with a one-factor completely randomised design (CRD) research design. The experiment consisted of three treatments, namely P1, P2, and P3, with amounts of 1000 grams, 2000 grams, and 3000 grams, respectively. Each treatment was repeated three times, resulting in nine experimental units. Observation data were analysed using the BNJ test at the 5% level to determine which treatment had a significant effect on yield. The test results show that the melinjo seed flattener can operate properly. In testing the capacity of the tool shows the greatest working capacity of the machine, P3, which is 28.73 grams/minute.  The processing time test shows that the treatment that produces the most time is P3 of 88 minutes.  In testing the weight of the flattener results show that P3 produces the most with a value of 2516.67 grams. It is necessary to make improvements to the hopper and redesign by calculating the bulk angle of melinjo seeds, so that melinjo seeds can easily go down to the rationing section. In addition, a stirrer is designed for melinjo seeds that are ready to be flaked with the flattening machine so that when roasting with a stirrer, the melinjo seeds that are still hot are immediately put into the hopper so that they can be flattened using the semi-automatic flattening machine.

Abstract

The Tray Dryer is one of the most widely used batch-type drying tools due to its simple design.  The configuration of the tray dryer consists of an arrangement of several racks with a convection drying system, where hot air is circulated onto the racks in a space to dry the products.  The tray dryer is capable of reducing the drying area dimensions and improving the contact of hot air with the material, making the drying process adjustable.  The purpose of this research is to understand how to determine the methods and design a tray dryer drying machine. The design of this tray dryer drying machine utilizes Solidworks software, comprising both structural and functional design. The temperature distribution of the tray dryer machine has the highest temperature on the top rack because the fan is less efficient in promoting temperature uniformity across each drying rack.  Thus, testing on the drying machine varies, where on the first rack, the temperature reaches 50°C, while on the second rack, it decreases to 49°C, and on the third rack, it is 45°C. This led to testing with the material of cherry leaf with an initial moisture content of 64.2%, obtaining moisture content after 90 minutes of drying on the first rack at 47.33%, on the second rack at 48.3%, and on the third rack at 53.6%.  So, in the testing process, different results are obtained for each rack.

Abstract

Penentuan tingkat kematangan buah sangat penting dalam industri pertanian karena memengaruhi kualitas, rasa, nilai gizi, dan daya simpan. Metode manual dinilai kurang akurat karena bersifat subjektif. Penelitian ini bertujuan mengembangkan sistem klasifikasi kematangan buah jeruk secara otomatis menggunakan sensor warna TCS3200 yang mendeteksi intensitas warna RGB (Red, Green, Blue). Metode penelitian eksperimental ini meliputi pembacaan nilai frekuensi warna pada sampel jeruk dengan tingkat kematangan berbeda, yaitu mentah, setengah matang, dan matang. Frekuensi diubah menjadi nilai RGB skala 0–255 dan dianalisis menggunakan rasio R/G untuk klasifikasi. Hasil menunjukkan bahwa buah mentah memiliki nilai R rendah dan G tinggi, sedangkan buah matang menunjukkan sebaliknya, dengan rasio R/G meningkat secara signifikan. Pola ini dapat dimanfaatkan untuk membedakan tingkat kematangan buah secara objektif dan efektif untuk di terapkan dalam bidang pertanian.
