Abstract

The North Sulawesi Province, widely recognized as the Coconut Waving Province owing to its substantial coconut tree population, primarily depends on copra production. This research presents a novel methodology for determining copra maturity levels by utilizing a Convolutional Neural Network (CNN) on digital photographs, classifying them into three distinct stages: raw, half-ripe, and ripe. By employing a rigorous 10-fold cross-validation technique, our models demonstrated remarkable performance. Notably, even the model with the lowest performance achieved a commendable accuracy of 87.78% during the training and validation phases. The model that exhibited the highest level of performance achieved a perfect accuracy rate of 100%. Moreover, when subjected to real-world testing situations using novel data, the model with the lowest performance exhibited a noteworthy accuracy of 83.34%. In contrast, the highest-performing model achieved a flawless accuracy of 100%. Based on the findings above, an online system has been built that leverages the most optimal model, facilitating the assessment of copra maturity in real-time. The prospects encompass the integration of this methodology into copra sorting machinery, thereby yielding advantages for both agricultural producers and industrial sectors. This research enhances copra quality control processes and promotes sustainability in the copra industry. Further research could explore refining the CNN model to accommodate a broader range of copra variations and investigating automation possibilities in copra production processes. These endeavors would advance the efficacy and applicability of copra maturity classification methods, fostering continued innovation in the industry.

Abstract

Mekanisasi pertanian merupakan introduksi dan penggunaan alat mekanis untuk melaksanakan operasi pertanian yang sangat diperlukan untuk menuju ke pertanian modern. Tujuan penelitian adalah untuk mengidentifikasi kebutuhan alat dan mesin pertanian dalam usaha tani tanaman padi sawah di dua kecamatan yakni Kecamatan Tombatu Timur dan Touluaan. Penelitian ini dilakukan dengan menggunakan metode survei dengan teknik observasi yaitu pengamatan dan pengambilan data secara langsung di lapangan, yang dilaksanakan selama 2 bulan yaitu pada bulan Mei – Juni 2023. Hasil penelitian menunjukkan bahwa alat pertanian paling banyak ditemui dalam usaha tani tanaman padi sawah di Kecamatan Tombatu Timur dan Touluaan adalah pengolahan hasil dan pemungutan hasil tanaman padi sawah yaitu pisau sabit, perontok padi dan RMU, Hand sprayer yang digunakan untuk pemberantasan hama dan penyakit tanaman padi dan tractor tangan untuk pengolahan lahan. Kontribusi masyarakat sangat besar terhadap kehadiran alat dan mesin dalam kegiatan usaha tani khususnya pada traktor tangan, dimana hal tersebut didasarkan pada tingkat minat petani untuk menggunakanya. Luas lahan yang tersedia untuk areal persawahan Kecamatan Tombatu timur seluas 1.117 ha dan Kecamatan Touluaan seluas 897 ha maka di dua kecamatan ini mengalami kekurangan tenaga kerja sehingga penambahan kebutuhan traktor tangan harus dilakukan yaitu Kecamatan Tombatu Timur 9 unit dan Touluaan 5 unit. Dengan demikian, diperlukan upaya yang lebih besar dari pihak terkait, terutama Dinas Pertanian, untuk mengoptimalkan penggunaan alat dan mesin pertanian yang sesuai dengan kondisi lokal. Sosialisasi yang efektif dan peninjauan kembali terhadap lahan pertanian yang ada dapat membantu memastikan bahwa teknologi pertanian yang digunakan benar-benar mendukung pertanian berkelanjutan dan produktif di Kecamatan Tombatu Timur dan Kecamatan Touluaan.

Abstract

Many coconut husks in coconut-producing área have not been maximally utilized, especially on a small scale for farmers. It happened due to the difficulty of obtaining simple small-scale coconut decomposing machines, and the region must import it from other regions. As a result, the utilization of coconut fiber in fiber and cocopeat is still minimal. Plus, when bringing in from outside, the logistics cost of the coconut husk decomposing machine is still high. This research aims to conduct a techno-economic analysis of a small-scale coconut husk decomposer from the machine designed and made. The research method was using the experimental method. The results showed that the equipment can produce cocofiber and cocopeat with 600 kg of husk per day for 6 hours of use. The results of economic calculations based on the IRR value, the net B/C ratio, and the payback period show that this machine is feasible to be developed on a small scale for Farmer groups. Technologically, this machine is simple and relatively easy to operate. Further research hopes this machine will prove its durability over long, heavy work periods.

Abstract

This study aimed to (1) examine the effect of giving PGPR (Plant Growth Promoting Rhizobacteria) to increase soybean growth and production and (2) obtain the best dose of PGPR to increase soybean growth and production. The research was carried out in Tontalete Village, Kema District, North Minahasa Regency, North Sulawesi from June 2021 to October 2021. The field experiment was arranged in a Randomized Block Design (RBD). The treatment tested was the concentration of PGPR, which consisted of  P0 = 0 ml/l (control), P1 = 5 ml/l, P2 = 10 ml/l, P3 = 15 ml/l, and P4 = 20 ml/l. The treatment was repeated three times, so there were 15 experimental units. Parameters observed were: plant height, number of branches, number of pods per plant, percentage of damaged pods per plant, the weight of 100 dry seeds, and seed yield/plot. The data were analyzed using the Analysis of Variance (ANOVA) and continued with the mean difference test using the Least Significant Difference Test (LSD) at the 5% level. The results showed that the application of PGPR affected the growth and yield of soybeans by increasing plant height, the number of pods per plant, and dry seed yield. The highest dry seed yield was achieved at PGPR concentrations of 10 ml/l and 15 ml/l, which were 1.34 g and 127.87 g, equivalent to 1.34 tons ha-1 and 1.28 tons ha-1, respectively.

Abstract

Macadamia (Macadamia integrifolia) is a high-value crop not widely known in Indonesia and still processed using conventional shelling methods that are time-consuming and inefficient. This study aimed to design and evaluate the PTR-TETA20 macadamia nut sheller to improve post-harvest efficiency. The research was conducted from May to July 2024 at the Faculty of Agriculture, Sam Ratulangi University. The methodology involved the design, construction, and performance testing of the machine using experimental methods and descriptive data analysis. The PTR-TETA20, measuring 30 × 23 × 113 cm and powered by a 1/4 HP motor with a pulley and V-belt system at 1467 RPM, was tested using 1 kg of macadamia nuts in three repetitions. The average working capacity reached 38.43 kg/hour, with a yield of 92.52%. Nut integrity was recorded as 40.22% whole, 36.10% halved, and 23.66% broken. Moisture content was 2.6% (whole), 2.56% (halved), 2.83% (broken), and 9.52% (shells). The results indicate that PTR-TETA20 offers a practical shelling solution for small-scale producers. However, machine performance can be improved by optimizing roller spacing and ensuring uniform nut drying.

Abstract

Postharvest damage to potatoes can occur due to plant physiological disorders, such as evaporation (transpiration), respiration (respiration), tubers sprouting, and tubers becoming too ripe. This research aims to design, manufacture, and test an evaporative cooling device using a direct spray method from a fan into a room or box by conducting technical tests about temperature, humidity (RH), signs of potato damage, weight loss, and water content. The test was carried out using an evaporative cooling device (evaporative cooler) for 30 days.    This research tested the effectiveness of the evaporative cooling system compared to room outside storage on potato quality for 30 days observationally. The results show that evaporative cooling equipment can prolong the shelf life of fresh potatoes in tropical areas according to physical parameters such as signs of damage to potatoes during storage, water content, and percentage of weight loss. For future development, increasing the fan and cooling pad to medium size is necessary for more effective equipment. An evaporative cooler is a cost-efficient and sustainable method for preserving agricultural produce in rural areas far from urban centers.
