Abstract

Seawater intrusion in Gili Trawangan, North Lombok Regency, can be identified through groundwater salinity testing. This study aims to evaluate changes in groundwater salinity values as an indicator of seawater intrusion in the region. The test was conducted by taking well water samples and analyzing them at the Lombok Island Health Laboratory. The results showed that the groundwater salinity value before the water withdrawal project by PT Berkat Air Laut in 2012 was 5.00‰. During the groundwater withdrawal project period (2013-2022), the salinity value increased to 5.71‰, and post-project, the salinity value reached 6.07‰. These findings indicate that groundwater in Gili Trawangan was classified as brackish water from the start, with increasing salinity values indicating seawater intrusion. However, this increase is still in the low category, at 0.71‰ during the project and 0.36‰ post-project, so it is not classified as significant water pollution.

Abstract

Bioslurry liquid fertilizer is one of the biogas wastes that has been utilized in improving soil fertility. Free-range maize has the potential to support increased production alongside hybrid maize. The study aimed to assess the role of bioslurri liquid fertilizer for the growth and yield of several genotypes of maize plants. The research was conducted on dry land in Nagari Batang Betung, Basa Ampek Balai Tapan District, Pesisir Selatan Regency from Juny to October 2023. The research used a factorial completely randomised design (CRD). The first factor was maize genotype consisting of; Sukmaraga and Bisma varieties, JK, and JM line. The second factor was bioslurri liquid fertiliser (ml/L water) with 3 levels namely: 0, 50, and 100. The observed variables were plant height, male flowering age, female flowering age, root length, root dry weight, top dry stover weight, cob length, cob diameter, cob dry weight, 100 seed weight, and dry kernel weight per ha. Data were statistically analyzed with F test and Duncan's further test at 5% real level. Data were analyzed using Statistix ver. 8. The study showed that there were no interaction of bioslurri liquid fertilizer on the growth and yield of several genotypes of corn plants, and bioslurri liquid fertiliser also had no significant effect on the growth and yield of maize. Strain JK produced better growth in height, cob length, 100-seed weight, and dry kernel weight per ha than strains JM, varieties Sukmaraga and Bisma. The dry kernel weight of JK strains reached 4.90 tonnes/ha. Line JK can be used as candidate for new maize high-yielding varieties of free-range maize.

Abstract

The research aims to determine the competition index and the maximum number of sedge populations that can be tolerated by peanut. In this regard, research has been carried out using additive, substitution and dynamic experimental models. The research results showed that the competition index of sedge when peanuts were 60 DAP was 0.0659 so that sedge were able to reduce peanut yields by 6.590%. Meanwhile, at 90 DAP the competition index is 0.0733, so that sedge have the potential to reduce peanut yields by 7.330%. The peanut yield loss calculated based on the weighted dominance variable is in accordance with the predictions of the sedge competition index, namely the yield loss of peanuts aged 60 DAP and 90 DAP is 66.00% and 72.60%. Meanwhile, based on the prediction of the sedge competition index, peanut yield losses were 65.90% and 73.30%. The growth of peanuts aged 60 DAP and 90 DAP began to be suppressed by the presence of 5.43 and 5.24 clumps per m2 of sedge, while for peanuts to suppress sedge growth, a population of 7.58 and 5.30 clumps per m2 was required. The presence of sedge that can be tolerated by peanuts aged 60 HST ≤ 5.43 clumps per m2 and aged 90 DAP ≤ 5.24 clumps per m2. The relative space occupation (RSO) of sedge when peanuts are 60 DAP is higher than the RSO of peanuts, whereas when peanuts are 90 DAP, the RSO of sedge is lower compared to the RSO of peanuts, namely the population density of peanuts and sedges 5-35 clumps per m2, the RSO value of peanuts is 57.00 – 94.00%, while the RSO value of nut weeds is 47.40 – 92.00%, with a comparative value of 9.60 – 2.00%

Abstract

This research aims to examine the effect of Silica fertilizer on cayenne pepper (Capsicum frutescens) under water stress conditions on the growth and yield of chili plants. The study was designed with a 2-factor treatment arranged in a completely randomized design (CRD). The treatments tested were the effects of various concentration of Silica fertilizer (0 ml/l, 2 ml/l, and 4 ml/l) under different soil moisture conditions (80%, 100%, and 120% field capacity). The parameters observed included plant height, canopy width, stem diameter, number of productive branches, number of flowers, number of fruits per plant, and fruit weight per plant. The results showed that the use of Silica fertilizer at different concentration under water stress conditions had no significant effect on growth parameters such as plant height, canopy width, and stem diameter. However, the application of 4 ml/l Silica fertilizer resulted in better outcomes compared to plants with no Silica or 2 ml/l Silica in terms of yield parameters, such as fruit set percentage, number of harvested fruits, and fruit weight. The best interaction between Silica fertilizer treatment and water stress conditions was found in the S2KL1 treatment (4 ml/l Silica, 80% field capacity) and S2KL2 treatment (4 ml/l Silica, 100% field capacity).

Abstract

Porang belongs to the Araceae family, which is a type of tuber plant classified under the genus Amorphophallus. Porang contains a high level of glucomannan, ranging from 5–60%. Glucomannan has various benefits, one of which is as a stabilizer in ice cream production, potentially improving the texture, viscosity, and stability of the product. Meanwhile, the protein in porang tuber flour is 9.20%, starch 76.5%, fiber 25%, fat 0.20%. This study aimed to determine the physicochemical and organoleptic properties of pumpkin (Cucurbita moschata) ice cream with the addition of porang flour as a stabilizer. The experiment consisted of five treatments: K1 (0%), K2 (0.2%), K3 (0.4%), K4 (0.6%), and K5 (0.8%) porang flour, arranged in a Completely Randomized Design (CRD) with four replications, resulting in 20 experimental samples. The observed parameters included protein content, fat content, viscosity, melting time, overrun, emulsion stability, and organoleptic properties. Data were analyzed using Analysis of Variance (ANOVA) at a 5% significance level with SPSS software. If significant differences were found, further testing was conducted using the Honest Significant Difference (HSD) test at 5% for physicochemical parameters. For organoleptic data showing significant differences, the Kruskal-Wallis nonparametric test was applied. The results showed that the addition of porang flour affected the physicochemical and organoleptic quality of pumpkin ice cream. The best treatment was obtained with the addition of 0.4% porang flour (K3), which produced ice cream with protein content of 5.57%, fat content of 6.74%, overrun of 30.06%, melting time of 56.64 minutes, viscosity of 49,130.00 mPa·s, and emulsion stability of 90.89%. The product also had a soft texture, yellow color, and flavor and aroma that were preferred by the panelists.
