Abstract

Pakcoy (Brassica rapa L.) is a widely cultivated leafy vegetable with high economic value. Limited agricultural land and the need for more efficient cultivation systems encourage the use of hydroponic technology, particularly through the use of pH and TDS sensors to optimize nutrient management. This study aims to compare the growth of pakcoy plants using the Deep Flow Technique (DFT) hydroponic system with pH and TDS sensors and without sensors. The study used a Completely Randomized Design (CRD) with two treatments: 50% AB mix + 50% POC with sensors, and 50% AB mix + 50% POC without sensors, with nine replications. The parameters observed included plant height, number of leaves, leaf area, fresh weight, and dry weight. Data were analyzed using an unpaired t-test at a significance level of 5%. The results showed that the use of pH and TDS sensors significantly affected all growth parameters. The treatment with sensors resulted in higher average values, namely plant height of 25.1 cm, number of leaves of 17.3, leaf area of 514.6 cm², fresh weight of 236.28 g, and dry weight of 30.7 g compared to the treatment without sensors. Automatic nutrient monitoring creates stable solution conditions, thereby increasing nutrient absorption efficiency and plant biomass accumulation. This study concluded that the use of pH and TDS sensors is effective in optimizing and increasing the productivity of bok choy plants in hydroponic systems. It is recommended that IoT-based monitoring technology be applied more widely to improve cultivation efficiency, reduce costs, and support sustainable agriculture.

Abstract

Lettuce (Lactuca sativa L.) is a vegetable commodity that is currently in high demand because it has many health benefits. Hydroponic cultivation is a method that can improve lettuce growth by utilizing IoT based pH and TDS sensors. This study aims to compare lettuce growth in hydroponic cultivation by applying Internet of Things (IoT)-based pH and TDS sensors and manual methods. The method used was an experimental method by comparing the average of two treatments, namely the use of IoT-based pH and TDS sensors and the manual method, with each treatment consisting of nine replicates. The results showed that the application of IoT sensors had a significant effect on increasing plant height, leaf area, wet weight, and dry weight. IoT technology can improve efficiency and productivity in hydroponic systems because the sensors can maintain a stable balance of nutrients and acidity in the solution, resulting in better plant growth. These findings indicate that the application of IoT has great potential in supporting sustainable agriculture, while also providing benefits in the form of increased production efficiency and resource savings.

Abstract

Nagari Talang Babungo di Kabupaten Solok merupakan daerah agraris penghasil gula merah berbahan baku tebu. Komoditas unggulan ini merupakan potensi lokal yang diolah menjadi gula merah. Namun, pengolahan gula merah masih menghadapi berbagai kendala, seperti kualitas produk yang belum seragam, kadar air tinggi, tekstur kurang padat, serta pengemasan sederhana sehingga produk kurang kompetitif di pasaran. Untuk itu dilakukan kegiatan pengabdian kepada masyarakat berupa pelatihan pembuatan, peningkatan kualitas, dan pengemasan gula merah tebu. Kegiatan dilaksanakan melalui metode penyuluhan, pelatihan praktik, serta pendampingan berkelanjutan. Peserta terdiri atas petani tebu, pelaku UMKM, dan masyarakat umum yang tergabung dalam kelompok tani Lestari Nagari Talang Babungo. Materi yang diberikan meliputi faktor-faktor yang mempengaruhi produksi gula merah, standar mutu gula merah, pengolahan pasca panen yang efisien, serta inovasi pengemasan yang menarik. Hasil kegiatan menunjukkan peningkatan pengetahuan dan keterampilan peserta. Produk gula merah yang dihasilkan memiliki warna lebih seragam, kadar air, dan dikemas yang menarik dan higienis sehingga dapat meningkatkan nilai jual. Disamping itu, peserta memperoleh informasi terkait pengendalian mutu gula merah dan teknis dalam pempersiapan kemasan. Program ini memberi dampak positif bagi kelompok tani Lestari secara ekonomi dimana gula merah berpotensi menjadi produk unggulan daerah Kabupaten Solok dan Sumatera Barat dengan daya saing lebih baik. Kegiatan ini juga meningkatkan kesadaran masyarakat terhadap standarisasi mutu gula merah, dan memperkuat kelembagaan usaha nagari dalam usaha berbasis potensi lokal.

Abstract

Phaleria macrocarpa (Scheff.) Boerl., referred to as Mahkota Dewa, is a valuable medicinal plant with significant economic importance, requiring effective propagation methods to enhance its cultivation. Grafting is a frequently utilized technique, and its effectiveness is affected by the kind of growth medium used. This study aimed to evaluate the effect of different planting media on root growth of grafted Mahkota Dewa. The research was carried out between January and March 2026 in Lubuk Minturun, employing a Completely Randomized Design (CRD) with three different treatments: soil (P0), sawdust (P1), and cocopeat (P2), each consisting of six replications. The parameters monitored included the number of roots, root length, and dry weight of roots. Data were evaluated by using analysis of variance (ANOVA). The findings showed that the type of growth medium did not have a significant impact (p>0.05) on any of the root growth parameters measured. These results imply that alternative mediums like sawdust and cocopeat can serve as replacements for soil without notably hindering root growth in grafted P. macrocarpa.
