Abstract

Lidah buaya mengandung polisakarida (glukomannan), antimikroba dan anti-inflammattory sehingga bisa digunakan sebagai bahan penyalut edibel (edible Coating). Penyalut gel lidah buaya lebih aman untuk kesehatan karena bersifat alami, tidak berwarna, tidak berbau, tidak mempengaruhi rasa, serta aman bagi lingkungan. Gel lidah buaya (GLB) mengandung bahan bioaktif yang berguna bagi kesehatan sehingga jika digunakan sebagai penyalut dapat menambah khasiat buah yang disalut. Bagian dalam lidah buaya berbentuk gel sehingga mudah diaplikasikan sebagai penyalut edibel. Akan tetapi, kendalanya gel lidah buaya mudah berubah konsistensinya sehingga untuk mempertahankannya harus ditambahkan bahan lain seperti gliserol. Penelitian ini bertujuan untuk mengetahui konsentrasi gliserol yang tepat pada penyalut gel lidah buaya agar mendapatkan karakteristik penyalut yang baik. Metode penelitian yang digunakan adalah metode analisis deskriptif. Percobaan dibagi 3 bagian, percobaan I bertujuan untuk mengetahui rasa GLB yang tepat, terdiri dari 5 perlakuan konsentrasi gliserol (0%, 0,5%, 1%, 2%, dan 3%), percoban II bertujuan untuk mendapatkan film GLB terbaik, terdiri dari 2 perlakuan konsentrasi gliserol (0,5% dan 1%), dan Percobaan III bertujuan untuk mengetahui daya lekat pada buah stroberi, terdiri dari konsentrasi gliserol (0,5% dan 1%). Penelitian dilaksanakan di Laboratorium Teknologi Pangan, Fakultas Teknologi Industri Pertanian, Universitas Padjadjaran, Jatinangor. Hasil penelitian I mendapatkan gel lidah buaya yang ditambahkan konsentrasi gliserol  0,5% dan 1 % tidak menimbulkan rasa pahit. Hasil penelitian tahap II mendapatkan gel lidah buaya yang ditambah konsentrasi gliserol 0,5% menunjukkan film terbaik dengan Water Vapour Transmission Rate 906,65 g/m2/24 jam dan kuat tarik 6,3 MPa. Hasil penelitian tahap III mendapatkan adanya lapisan penyalut yang melindungi buah stroberi dengan baik pada konsentrasi gliserol 0,5%.

Abstract

The butterfly pea (Clictoria ternatea) is one of the horticulture plants. It is part of the ornamental plant group. This plant has many uses, such as food colouring and herbal remedies. Butterfly peas are cultivated organically. However, there needs to be more research regarding adding varieties of organic fertilizers and different fertilization intervals to the plant. The research was executed in Sukalaksana Village, Samarang Subdistrict, Garut Regency, whereas the quality analysis was completed in the Horticulture Cultivation Department of UNPAD Agriculture Faculty. Experimental design of factorial Rancangan Acak Kelompok (RAK) / Randomized Block Design was used. The main factor is the liquid organic fertilizer, made from three different materials: banana stems LOF, chicken manure LOF, and Nasa LOF. The second factor is the fertilization intervals, which were scheduled in three different intervals: once a week, once every two weeks, and once every three weeks. Each interval was repeated three times. Results showed interaction between organic fertilizer types and fertilization intervals on leaf numbers, shoot and roots ratio, number of flowers and flower weight. The best interaction was LOF chicken manure types with fertilization intervals of 3 weeks, which gave higher results in the number of leaves, shoot and root ratio, number of flowers per plant, flower weight per plant and antioxidant content.

Abstract

Produktivitas cabai merah besar (Capsicum annuum L.) di Indonesia tahun 2019 sebesar 8,62 ton/ha dimana angka tersebut masih jauh di bawah potensi produktivitasnya (20-30 ton/ha). Angka produktivitas tersebut dapat ditingkatkan dengan pemupukan yang tepat. Controlled Release Fertilizer (CRF) merupakan pupuk yang dikembangkan untuk menyediakan nutrisi dalam kurun waktu lebih lama dan konsisten dengan kebutuhan nutrisi fisiologis tanaman. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh CRF terhadap pertumbuhan dan hasil tanaman cabai merah besar. Penelitian ini dilaksanakan pada bulan Februari-Juni 2022 pada kebun percobaan di Bale Tatanen, Universitas Padjadjaran. Penelitian dilaksanakan menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari enam perlakuan dan empat ulangan, yaitu: campuran pupuk tunggal (300 kg/ha Urea, 200 kg/ha TSP, dan 200 kg/ha KCl), NPK konvensional 300 kg/ha, CRF 2 240 kg/ha, CRF 2 300 kg/ha, CRF 3 240 kg/ha, dan CRF 3 300 kg/ha. Hasil penelitian menunjukkan pengaplikasian CRF memberikan pertumbuhan dan hasil tanaman cabai yang lebih baik dibandingkan dengan campuran pupuk tunggal dan pupuk NPK konvensional dilihat dari tinggi tanaman, diameter batang, indeks klorofil daun, jumlah buah cabai per tanaman, dan bobot buah cabai per tanaman namun tidak menunjukkan perbedaan signifikan untuk panjang dan lebar daun, bobot per buah cabai, serta panjang dan diameter buah cabai. Perlakuan yang memberikan pengaruh terbaik adalah pupuk CRF 2 dosis 300 kg/ha.

Abstract

Potatoes are the third most consumed food in Indonesia. The availability of high-quality potato tuber seeds is still low which affects potato production. Potato planting in the highlands is limited, so it needs to be expanded into medium lands. The modification that can increase the production of G0 potato tuber seeds on medium lands is the use of biochar and retardant. The purpose of this research was to determine the composition of biochar and the type of retardant to increase the G0 tuber seed yield of potato cv Medians in the medium lands of Jatinangor. The research was conducted from August 2022 to February 2023 at the Station Ciparanje, Jatinangor, Faculty of Agriculture, Universitas Padjadjaran. The experiment used Factorial Randomized Block Design (RBD). The first factor was the biochar compositions: b1 (100% compost), b2 (80% compost + 20% rice husk biochar), b3 (80% compost + 20% coconut shell biochar), and b4 (80% compost + 10% biochar husk rice + 10% coconut shell biochar). The second factor was the retardant type: r1 (without retardant), r2 (100 ppm paclobutrazol), and r3 (100 ppm prohexadione-Ca). The experimental results showed that there was no interaction effect of biochar compositions and retardant type on the growth and yield of G0 potato tuber seeds. Treatment of 80% compost + 20% coconut shell biochar suppressed plant height but increased the number of tubers. Treatment of 100 ppm paclobutrazol resulted in lower plant height but total chlorophyll content, percentage of stolon forming tubers, the number of tubers, and tuber weight per plant were higher compared to treatments without retardant and with 100 ppm prohexadione-Ca.

Abstract

Potato seed production in the medium plain is necessary to avoid environmental damage and the limited area of potato seed production in the high plain. The effort to increase the production of G1 potato seeds on the medium plain is the evaluation of the biochar composition and concentration of paclobutrazol that can increase the production G1 potato seeds cv Medians in the medium plain of Jatinangor. The research was conducted from August to December 2022 at the Ciparanje Experimental Field. Jatinangor. Faculty of Agriculture. Universitas Padjadjaran. The experiment used a Factorial Randomized Block Design (RBD). The first factor was the biochar composition: m1 (100% compost), m2 (80% compost + 20% rice husk biochar), m3 (80% compost + 20% coconut shell biochar), and m4 (80% compost + 10% biochar husk rice + 10% coconut shell biochar). The second factor was the paclobutrazol concentration: p1 (without paclobutrazol), p2 (100 ppm paclobutrazol), and p3 (150 ppm paclobutrazol). The experimental results showed that there was no reaction effect of biochar compositions and paclobutrazol concentrations on the growth and yield of G1 potato seeds. The application of 80% compost + 20 % rice husk biochar gave significantly higher yields than treatment without biochar. The number of tubers was 6.29 knol per plant and the tuber weight was 66.80 g per plant. Application of 100 ppm paclobutrazol resulted in lower plant height, gave the number of tubers was 6.39 knol per plant, tuber weight per plant was 63.34 g higher than without paclobutrazol and produced more seed tubers with S class.

Abstract

Potato growth is influenced by seed provenance and fertilization, but the availability of high-quality potato seeds is still limited. To overcome those challenges, solutions include using temperature-tolerant potato varieties from medium plains and applying organic fertilizers to improve potato growth and yield. The purpose of this research was to determine the effect of the interaction between seed provenance and application of organic fertilizers on the growth and yield of G2 potato seeds of the Medians cultivar in the Jatinangor medium plains. The research was conducted from June to October 2023 at the Ciparanje Experimental Farm, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor. The research design used was a Factorial Randomized Group Design (RBD). The first factor is the provenance of the potato seeds from the medium and high plains. The second factor is the type of organic fertilizer, namely chicken manure, cow manure, and guano fertilizer. The results showed that there was no interaction between the seed provenance and types of organic fertilizer on the growth and yield of G2 potato seeds of the Medians cultivar in Jatinangor medium plains. The use of seeds from medium plains had a significant effect on plant height, plant dry weight, and the percentage of stolons forming tubers. The application of cow manures with a dose of 225 g gave the best effect on leaf area, the number of tubers, and the weight of tubers per plant.

Abstract

Gibberellin (GAs) promotes plant growth processes like germination, shoot elongation, root development, and flowering, while its inhibition is occasionally used in some vegetable crop practices. This paper aims to review the current literature on GAs inhibitors in practical vegetable crops and suggest future strategies for increasing yield. In some vegetable crops, inhibiting GAs with natural (abscisic acid, ethylene) or synthetic (paclobutrazol, prohexadione-Ca) regulators is key to improving yield and quality. Abscisic acid (ABA) counteracts GAs in germination and stress adaptation, while ethylene (ET) opposes GAs in senescence and growth inhibition. The application of paclobutrazol (PBZ) and prohexadione-Ca (Pro-Ca) is known to inhibit synthetic GAs, resulting in denser plants while improving plant photosynthetic efficiency, which improves crop yield. Achieving desired growth and yields with GAs inhibitors relies on precise dosing, emphasizing the importance of review studies for advancing vegetable cultivation.

Abstract

The impact of tailings accumulated on agricultural land is the loss of soil profile and decreased soil quality, making plants difficult to grow. This study aimed to observe the effect of cow dung manure (CM) doses to gold mine tailings on total fungal and bacterial populations of soil surrounding roots and water spinach biomass and to analyze the correlation between fungal and bacterial populations with water spinach growth parameters. The experiment was designed in a randomized block design with five treatments and five replications. The treatments included without CM (control) and 5, 10, 15, and 20% of CM in tailing. Similar treatments were added to plants grown in mineral soil, i.e. Inceptisols. The results determined the retarded plant growth in tailing compared to that in Inceptisols. The plant grown in tailing was more responsive to manure amendment. The CM increased total fungal and bacterial populations in the soil around the roots, plant height, leaf number, stem thickness, wet weight, and dry weight of intact plants. Applying 5% of CM caused better growth of water spinach than other treatments. Total fungal and bacterial populations were strongly correlated with water spinach height and dry weight. ABSTRAK Dampak negatif penumpukan tailing di lahan pertanian adalah hilangnya profil tanah dan penurunan kualitas tanah sehingga tanaman sulit tumbuh. Penelitian ini bertujuan untuk mengobservasi pengaruh pemberian dosis pupuk kotoran sapi (PKS) pada tailing tambang emas terhadap populasi jamur dan bakteri total biomassa kangkung darat (Ipomoea reptans (L.) Poir.) serta menganalisis korelasi antara populasi jamur dan bakteri di tanah sekitar perakaran dengan parameter pertumbuhan kangkung. Percobaan pot di rumah kaca disusun dalam rancangan acak kelompok dengan lima perlakuan dan lima ulangan. Perlakuan percobaan adalah tanpa dan dengan penambahan 5, 10, 15 dan 20% PKS ke dalam tailing. Perlakuan yang sama diberikan pada tanaman kangkung dengan tanah Inceptisol. Hasil percobaan menunjukkan bahwa pertumbuhan kangkung di tailing terhambat dibandingkan di tanah Inceptisols, tetapi tanaman di tailing lebih responsif terhadap aplikasi PKS. Pupuk kotoran sapi mampu meningkatkan populasi jamur dan bakteri total di sekitar perakaran, tinggi tanaman, jumlah daun, ketebalan batang, bobot basah serta bobot kering tanaman di tailing. Pemberian 5% PKS lebih meningkatkan pertumbuhan tanaman kangkung dibandingkan dengan perlakuan lainnya. Populasi jamur dan bakteri masing-masing berkorelasi positif dengan hubungan yang sangat kuat dengan bobot kering serta tinggi tanaman kangkung. Percobaan ini menjelaskan bahwa bahan organik penting untuk memperbaiki kualitas tailing dan pertumbuhan tanaman.
