Abstract

Modeling science has been applied by many advanced countries in many fields, such as geology, meteorology, climate change, crop productivity, environment, erosion, and landslide. The crop model simulates the processes of agriculture. The writing of this article is descriptive qualitative using the Systematic Literature Review (SLR) method. So far, each model has its advantages and disadvantages but generally is based on the physiology of the growth and development of crops in relationship with soil, climate, solar radiation energy, and limiting factors to plant growth. There have been many models for rice that can forecast yield and biomass or predict future climate change dynamics. Meanwhile, many models such as DSSAT, AquaCrop, Oryza, APSIM, EPIC need more data to operate their modeling, which in many cases, data is not readily available. In this review, we would like to introduce the model “SIMPLE” which includes only thirteen parameters and four of which describe cultivar characteristics. Another advantage of “SIMPLE” is that it can be adapted for many crop species and added variable modules such as nutrient dynamics, water stress, temperature stress, or pests. It is entirely open source based on R programming, but limitations still exist that have been mentioned in the review.

Abstract

Rubber seeds from the Musi Rawas region in South Sumatra have great potential for rubber seed plantations. However, their utilization has not been maximized and they are often treated as plantation waste. This research aims to obtain the characteristics of rubber seeds as raw materials for biofuel production, so that the rubber seeds from the South Sumatra region can be utilized by the community and not just considered as plantation waste. In the first treatment, the rubber seeds are crushed to obtain the seed coat and the kernel. The crushed rubber seed shells are finely ground and sieved, while the kernel is pressed to extract vegetable oil using a pressing tool. The test methods used to determine the characteristics of the rubber seed shells include proximate analysis and calorific value, while GC-MS analysis is employed for the rubber seed oil. The proximate analysis of the rubber seed shell (RSS) yielded the following results: moisture content of 15.97 wt%, volatile matter of 47.43 wt%, fixed carbon of 32.45 wt%, and ash content of 4.15 wt%. The calorific value of the rubber seed shell was found to be 3312.8694 calories per gram. For the GC-MS yield of the rubber seed oil, the composition is as follows: palmitic acid 7.32%, linoleic acid 34.69%, oleic acid 45.35%, and pentadecanoic acid 8.86%. Based on the obtained results, rubber seeds show promising potential as raw materials for biofuel production through the pyrolysis process.

Abstract

Grape (Vitis vinifera) cultivation is hampered by a lack of suitable land and challenging nurseries. Use of crimson yellow podzolic soil for vine cuttings can be suboptimal. Although podzolic soil has a low capacity to absorb macro- and micronutrients and an acidic pH, it can nevertheless be used as a growing medium. A synthetic growth regulator (ZPT) bath of naphthalene acetic acid (NAA) needs to be added to the local red master grape variety, which has started to develop as a scion in nurseries. In order to assess the impacts of NAA-soaked concentrations on podzolic soil media and identify the morphological traits of local Red Master grape cuttings, this study set out to identify these traits. Its goal was to find out how auxin affected the development and yield of grapes (Vitis vinifera L.) grown in red yellow podzolic soil. A non-factorial totally randomized design with one factor (NAA concentration) was used in the study, with a block of 4 treatments and 3 repetitions. The varied NAA concentrations used in the treatment procedure included F0 (0 g L-1), F1 (2 g L-1), F2 (4 g L-1), and F3 (6 g L-1). The variables that were observed included the number of shoot bursts, the timing of leaf emergence, the number of sheet leaves, the length of the tendrils, and the proportion of live cuttings. ANOVA was used to tabulate and analyze observational data at a 5% level, and DMRT analysis was used to continue the analysis at the same level. According to the results, soaked NAA at a concentration of 0 g L-1 (S0) as the control treatment had the best results for the variable number of shoots and leaves, while a concentration of 2 g L-1 (S1) had the best results for the variable length of tendrils. However, soaked NAA had no significant impact on the variable when leaves emerged. Soaking auxin at the bottom of cuttings had no effect on shoot formation. Reduction of auxin due to defoliation can result in the expression of the isopentenyl-transferase (IPT) gene. Auxins, such as Indole-3-acetic acid (NAA), are usually involved in the regulation of root and leaf growth. If a plant has many leaves and few roots without the use of additional NAA or auxin, several factors may play a role, such as plant genetics, environmental conditions, and environmental stress. The use of additional NAA or auxin can explicitly affect the growth of roots and leaves. The survival percentage of cuttings is still low because it is influenced by the quality (material) of the cuttings, the age of the parent tree, growing media and water availability.

Abstract

Plastic is one of the most widely used packaging materials. Plastic is made of chemicals that are highly toxic, and its use has produced a lot of waste that is bad for the environment and difficult to decompose. The global community is becoming more and more aware of the value of high-quality food, particularly when it comes to packaging that is safe for human health and the environment. Edible films can be used as an eco-friendly alternative to plastic food packaging options. As a material for packaging, edible film made of biopolymers has been created. This material can be made from biodegradable components and has qualities akin to those of ordinary plastics. When combined with zinc oxide (ZnO), a piezoelectric ceramic with anti-microbial properties, edible film degrades and decomposes readily. This study sets out to identify the effects of variations in zinc oxide nanoparticle concentration properties of edible films made from corn starch (Zea mays L.) and to establish the optimal zinc oxide nanoparticle concentration. ZnO concentrations ranging from 0% to 3% to 9% to 12% were used. The outcomes demonstrated that a concentration of 12% provided the optimal treatment for the properties of edible film. With the addition of 12% ZnO concentration, the edible film's properties improved the most in this investigation, showing 81.94% water resistance, 1.434 MPa tensile strength, and 38.46% elongation percent. The lowest biodegradability value was found in edible film with a concentration of ZnO 12%, within 14 days. The resistivity, tensile strength, and % elongation of the edible film increase with increasing ZnO content.

Abstract

Artificial light in indoor plant production is still a challenge related to the amount of electrical energy used, such as in the Pakcoy plant. The Pakcoy plant has nutritional and economic value and is usually used as a research indicator plant. This study aimed to determine the effect of artificial light irradiation on the growth and yield of Pakcoy plants. The research was conducted in a plant factory in an indoor hydroponic system, with LED light of 100 umol/m2/s as a light source for the growth of Pakcoy plants. The artificial light irradiation length treatment consisted of 4 levels, namely 12 hours/day, 16 hours/day, 20 hours/day, and 24 hours/day. The most significant growth, yield, and content of vitamin C in Pakcoy plants were obtained in maximum artificial light exposure for 24 hours/day, and the highest protein content was obtained in the long irradiation treatment for 16 hours/day.

Abstract

Changing the ingredients also can change the properties of the bread. In this study, bread was made using rice flour and sourdough. Sourdough with Lactic Acid Bacteria (LAB) and yeast can also be added with pineapple starter to help microbiota growth. The study aimed to determine the amount of microbiota produced from sourdough with pineapple addition and its effect on the texture of rice flour bread. Pineapples with water and sugar were fermented to make pineapple starter. Pineapple starter is then used in sourdough making and fermented around 3-6 days. The mature sourdough was used in bread making. The addition of pineapple, in the form of a starter, made the pineapple sourdough (PS) have lower pH and higher titratable acidity (TA), total Lactic Acid Bacteria (LAB), and total yeast than sourdough without the addition of pineapple starter or wheat sourdough (WS). The pH and TA of PS at the peak were 3.25 and 2.67 mL of NaOH. The total LAB of PS at the peak was 9.27 Log CFU/g, and the total yeast was 9.30 Log CFU/g. PS reached its peak on the third day, while wheat sourdough (WS) reached it on the sixth day. The pineapple sourdough bread (PSB) had the lowest specific volume, and the highest texture properties compared to control bread (CB) and wheat sourdough bread (WSB), but there is no significance different. The addition of pineapple starter can fasten the fermentation time of sourdough and made the bread less brittle than CB.

Abstract

Forest conversion to oil palm plantations forms a unique agroecosystem. Forests known as a source of biodiversity are bordered by oil palm plantations with low diversity. The location of the oil palm plantation, which is directly adjacent to the forest, is thought to affect the diversity of spiders found in the agroecosystem. This study aimed to determine the effect of the distance between oil palm plantations and forests on spider diversity. The research was conducted at oil palm production centers in West Sumatra Province, Indonesia, namely Dharmasraya Regency, Pulau Punjung District, Nagari Gunung Selasih, and Sungai Kambut. In oil palm plantations, 10 sample plots (1 m x 1m) were determined along the transect line, 1 km from the forest's edge. Spiders were collected using the pitfall trap, knockdown, and hand collection methods. The spider diversity was analyzed by applying the diversity and evenness index by Shannon-Wiener. The results showed that the distance of the oil palm plantation from the forest affected the diversity of spiders. The closer the oil palm plantation is to the forest, the higher the diversity of spiders. The results of this study can be one of the considerations for oil palm business actors to maintain forests as conservation areas for organisms that provide various ecosystem services, including spiders as predators of oil palm pests.

Abstract

Organic rice cultivation is one of the technologies developed in Indonesia around two decades ago, but it is not growing as expected. Indeed, organic rice production is considered less effective than conventional farming. This review article explores the role of agronomic factors in organic rice cultivation related to organic nutrient availability and plant spacing. The proposed alternative solutions for using organic inputs to improve soil fertility and increase crop yields are also discussed. The effectiveness of organic fertilizers to chemical fertilizers based on the Rice Agro-advisory Service shows that organic rice has lower yields than conventional farming. The yield reduction ranges between 0.5 and 2.2 t ha−1 or around 9 to 43%, depending on organic amendments and site characteristics. It is also proven that applying high-nitrogen nutrients from organic fertilizers does not increase rice production. Application of nitrogen fertilizers in the right amount and at the correct plant stage  is more essential because it affects the yield component of rice plants. Narrower plant spacing in transplanted organic rice results in higher productivity. An increase in plant population higher than 25 hills m−2 no longer significantly increases rice yields. Among the agronomic factors that affect organic rice cultivation are the diversity of organic amendment in nutrient mineralization, especially nitrogen, according to plant needs, and narrow plant spacing that allows lesser weeds to grow among crop plants. These two agronomic factors need to be considered and applied by farmers to get the optimum growth and yield of organic rice cultivation.

Abstract

In principle, shallot can adapt to all altitudes. But in West Sumatera, it is generally cultivated in the highland. The problem is the area in the highland is very limited while the area in lowland land is dominated by Ultisol soils. The type of soil in Agricultural Faculty experimental field at Andalas University is Ultisol (250 asl) but the chemical properties slightly change, such as nitrogen, phosphor and potassium higher than usual otherwise SO42- and Ca-dd is still very low. This study aimed to obtain the best organic fertilizer and ZA fertilizer on the growth, yield and quality of shallot bulb on recovered Ultisols. The research was a-two factorial experiment with 3 replications in Completely Randomized Design. The first factor is the application of various types of organic fertilizer, which include three levels which are guano, chicken manure, and oil palm empty bunches (OPEB). The second factor is ZA fertilizer dosage (0, 100, and 200 kg/ha). Data were analyzed using the F test with a 5% level, and if there were significant differences, the analysis continued with the Duncan’s New Multiple Range Test (DNMRT) at a 5% level. The result showed that the development of shallots on recovered Ultisols brings hope. The yield of chicken manure and guano are higher than oil palm empty bunches and in accordance with the description of Bima Brebes varieties around 9 t/ha. Even guano could produce dry bulbs around10,54 t/ha without giving ZA. Moreover, guano fertilizer gave the best Sulphur content on every dose of ZA.
