Abstract

The increase in demand for sweet potatoes was not accompanied by an increase in production caused by a reduction in the area planted with sweet potatoes due to land conversion from wetlands to marginal lands. However, the available land for the expansion of agricultural areas is dominated by acid soils that are poor in nutrients. The main problem of planting in acid soil is the high content of Aluminum (Al). One of the effective approaches to selecting plants that are resistant to Al is using the solution culture method by adding Al and adjusting the pH of the solution. This activity aimed to obtain and develop the most appropriate and efficient screening method for selecting the resistance of some sweet potato germplasm to Al stress. The plant materials used were several collections of sweet potato germplasm, namely: Antin 1, Antin 3, Beta 1, Beta 2, Kidal, Papua Salosa, Sari, and Sarwentar. The research activities included: (1) Screening of sweet potato shoots in Al solution culture media in the form of AlCl3.6H2O with concentrations of 0, 100, 200, 300, 400, and 500 mg/L with a solution pH of 4.0 and (2) Testing of sweet potato Al tolerant on acid soils, namely yellow red podzolic soil from Bagoang Jasinga Village, Bogor Regency, Indonesia with a pH of 4.4-5.2. The results obtained were two sweet potato varieties that were tolerant of Al and acid soils, namely Kidal and Papua Salosa. Both of these varieties can be used as Al-tolerant and acid-soil-tolerant sweet potato planting material. Meanwhile, Antin was used as a comparison plant material that was intolerant of Al and acid soil.

Abstract

This research aims to determine the influence of liquid biofertilizer BRE4 and organic fertilizer on soil nematode diversity in Arabica coffee plantations. The study was conducted in smallholder Arabica coffee farms in the Ijen Bondowoso region, Indonesia. The research utilized a Randomized Complete Block Design with the following treatments: P1= 30 ml of liquid biofertilizer BRE4 per ton of manure, P2= 60 ml of liquid biofertilizer BRE4 per ton of manure, P3= 90 ml of liquid biofertilizer BRE4 per ton of manure, P4= 120 ml of liquid biofertilizer BRE4 per ton of manure, K- = Without liquid biofertilizer and manure, K+1= 60 ml of liquid biofertilizer, and K+2= 5L of manure without liquid biofertilizer. The results showed that the P4 treatment reduced the population of parasitic nematodes and increased the diversity of free-living nematodes better than other treatments. A total of 18 genera of soil nematodes were identified, with the bacterial-feeding nematode genus (bacteriovore) being the most abundant compared to other trophic groups. The application of BRE4 and manure improved the soil ecosystem based on the nematode diversity level.

Abstract

The presence of bobontengan weed (Leptochloa chinensis) in rice fields is considered to be detrimental and need to be controlled. Compounds secondary metabolites plant can be used as herbicides for weed control. Cacabean (Ludwigia hyssopifolia) is one of the plants that contain secondary metabolites compounds. This study aimed to determine the potency of the extract of each part of cacabean plant and the level of concentration in germination and growth of bobontengan. The research was carried out from February to March 2023, in the Integrated Field Greenhouse, Faculty of Agriculture, University of Lampung. The research design used a Randomized Block Experiment Design (RAK). The treatment consisted of two factors with four groups. The first factor was the source of cacabean extract: leaves, stems and roots, while the second factor was the concentration of cacabean extract which consisted of 4 levels: 0, 5, 10 and 15%. The homogeneity of variance was tested by Bartlett's test and the additiveness of the data was tested by Tukey's test. If the assumptions are met, the data is analyzed by analysis of variance and differences in treatment mean values followed by the Least Significant Difference (LSD) test at the 5% level. The results showed that extracts of leaves, stems and roots of cacabean at concentrations of 5, 10 and 15% effectively suppressed seed germination and bobontengan weed growth. L.hyssopifolia leaf extract was most effective in suppressing germination, shoot height growth, and dry weight of bobontengan weed. Cacabean leaves and stem extracts were most effective in suppressing the percentage of germination, shoot height growth, and the total dry weight of bobontengan. Concentration of 15% of Cacabean extract was most effective in suppressing the growth of shoot height of 2 MSA, root length, and dry weight of bobontengan, while the concentration of 10-15% was most effective in suppressing the percentage of germination and shoot height of 4 MSA. Sources of cacabean leaves, stem and root extracts were influenced by the level of extract concentration in suppressing seed germination and crown height.

Abstract

ABSTRACT Sanren F1 shallot is a type of TSS variety that is widely cultivated by Indonesian onion farmers. The cultivation of Sanren F1 shallots is faced with the constraints of non-uniform germination and low seed viability, thus affecting seed quality and yield of TSS shallots. Plasma light radiation is one of the fast, economical and pollution-free plant breeding methods to improve seed performance and yield. This study aims to determine the effect of plasma light period on the germination rate of shallots from TSS seeds of Sanren F1 variety. The research design used was a single-factor Completely Randomized Design (RAL). The factor used is the irradiation period with 6 levels, namely: P0 (control), P1 (5 minutes radiation), P2 (10 minutes radiation), P3 (15 minutes radiation), P4 (20 minutes radiation), and P5 (25 minutes radiation). The variables observed were germination power, germination rate, seed vigor and sprout height. The data obtained were analyzed using Analiysis of Variance (ANOVA) at 95% confidence level for the formation of the results significantly influenced or not. If influential then continued with Duncan's Multiple Range Test (DMRT). The results showed that plasma light treatment at the irradiation level of 15 minutes (P3) gave a real effect on the growth parameters, namely germination height and was able to increase the germination and seed vigor to 100%.

Abstract

The hard and thick structure of snakefruit seeds makes it difficult for snakefruit seeds to germinate, therefore efforts are needed to break the dormancy of snakefruit seeds. The aim of the research was to determine the method of breaking dormancy and the appropriate seed planting position to increase the viability of snakefruit (Salacca edulis Reinw) seeds, which was carried out at the Green House of the Agriculture, Fisheries and Forestry Extension Center (BP3K). The research method uses a factorial pattern in a completely randomized design. The first factor is the dormancy breaking method which consists of 5 levels, namely control, atonic, gibberellin (GA3), 60oC hot water, and sanding. The second factor is the position of planting seeds which consists of 3 levels, namely upright, lying down and upside down. Data analysis was carried out using ANOVA with a DMRT further test at 5% level. The research results showed that the method of breaking dormancy had an effect on the viability of snakefruit seeds. A good method of breaking dormancy is with GA3. The position of seed planting influences the viability of snakefruit seeds. The positions for planting seeds that have a good effect are the upright and lying positions. There was an interaction between the method of breaking dormancy using GA3 and the planting position of the lying seeds on the viability of the snakefruit seeds.

Abstract

Emergency Food Product (EFP) is a special food used in emergencies such as disasters by paying attention to criteria such as safe, palatable, easy to distribute, easy to consume, and nutritionally complete. Biscuits are processed products that can be developed to meet EFP criteria. Biscuits have a crunchy and dry texture so that they can last a long time and are favored by the majority of people. The main ingredient in making biscuits is wheat flour. However, it can be modified by utilizing local commodities such as porang and corn. Therefore, research needs to be done to get the right formulation for making biscuits made from local flour so that they can meet EFP criteria. This study used the factorial Complete Randomized Design (RAL) method, which consists of two factors, local flour formulation and dough pretreatment temperature. Analysis of the chemical characteristics including moisture, ash, protein, fat, carbohydrate, crude fiber content, and calories. The results showed that the formulation provided significant differences in moisture, ash, fat, protein, crude fiber, and carbohydrate content of local flour biscuit prototypes. The temperature difference of pretreatment (-18°C or 4°C) for 30 minutes before molding provides significant differences in moisture, fat, crude fiber, and carbohydrate content of local flour biscuit prototypes. Based on the number of calories per 50 gr of products, all prototypes of local flour biscuits with pretreatment at -18°C showed calories with an average of 234 kcal, meeting the calorie density requirements of emergency food products, which is a minimum of 233 kcal / 50 gr and a maximum of 250 kcal / 50 gr

Abstract

Catharanthus roseus L., atau tapak dara menarik perhatian luas karena kekayaan senyawa bioaktifnya, terutama flavonoid yang bermanfaat bagi kesehatan. Oleh karena itu, diperlukan teknik perbanyakan yang cepat dan efektif untuk memperoleh metabolit sekunder pada tanaman ini. Tujuan penelitian adalah mempelajari pengaruh aplikasi Elicitor Cu2+ terhadap morfologi kalus Catharanthus, dan mengetahui konsentrasi Elicitor Cu2+ terbaik dalam meningkatkan kandungan senyawa flavonoid pada Catharanthus. Penelitian kultur kalus dilaksanakan di Laboratorium Biosains dan Bioteknologi Reproduksi Tanaman, Gedung Teaching Industry, Jurusan Fakultas Pertanian Universitas Hasanuddin Makassar, dan analisis senyawa flavonoid dilakukan di Laboratorium Farmakognosi-Fitokimia Fakultas Farmasi Universitas Muslim Indonesia Makassar. Penelitian ini menggunakan rancangan acak lengkap (RAL) empat taraf konsentrasi Cu2+ yaitu 0 ppm, 4 ppm, 6 ppm, dan 8 ppm dengan tiga kali pengulangan. Setiap satuan percobaan terdiri dari 3 botol kultur. Data dianalisis menggunakan analisis varian dan uji lanjut BNJ 5%. Hasil penelitian menunjukkan bahwa penambahan elisitor Cu2+ 4-8 ppm pada media pertumbuhan kalus tidak bersifat toksik pada kalus, sehingga sel-sel kalus masih aktif membelah yang ditunjukkan oleh kalus yang kompak dan berwarna kuning kehijauan. Penambahan elisitor Cu2+ dengan konsentrasi 6 ppm mampu meningkatkan kandungan senyawa flavonoid pada kultur kalus Catharanthus roseus. Penggunaan elisitor Cu2+ berpotensi untuk dikembangkan untuk memproduksi senyawa sekunder pada tanaman obat.

Abstract

Increased plant productivity can be achieved through the development of organic fertilization technology that utilizes local organic matter that is easily accessible to farmers. An example is the use of manure from cow and goat manure, as well as forage such as kirinyuh and gamal. This approach offers a solution to the low productivity of rice in drylands. The use of organic fertilizers in various doses is expected to improve soil nutrient status while increasing rice productivity in dry land. This research was carried out on farmers' land in Ponu Village, Biboki Anleu District, North Central Timor Regency, East Nusa Tenggara, which is located in the RI-RDTL border area, precisely the Oekusi section. The experiment in this study was designed in a Group Randomized Design consisting of 10 treatments. The treatment is No Fertilization (P0D0), 10 tons of cow manure fertilizer (PsD1), 20 tons of cow manure fertilizer (PsD2), 30 tons of cow manure (PsD3), 10 tons of goat manure (PkD1), 20 tons of goat manure (PkD2), 30 tons of goat manure (PkD3), 10 tons of forage (PhD1), 20 tons of forage (PhD2), and Forage fertilizer with a dose of 30 tons (PhD3). Each treatment was repeated 4 times so that there were 40 experimental plots. The results showed that the combination of goat manure treatment with a dose of 30 tons/ha (PkD3) had a better effect than other treatment combinations. This combination of treatments was able to provide the best observation value on several parameters, namely plant height growth, the number of saplings and the number of panicles per clump as well as the production of dry grain weight harvested per plot.
