Abstract

Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) is a major polyphagous corn pest that has caused significant corn yield losses in Indonesia. Synthetic insecticides are still the primary choice, but their effectiveness in the field against S. frugiperda larval mortality is determined by the active ingredient and concentration used. This study aimed to evaluate the efficacy of several synthetic insecticides with the active ingredients cypermethrin, abamectin, and a combination of emamectin benzoate + chlorfenapyr on the mortality and time-response of S. frugiperda larvae on corn plants through laboratory testing. The study used a completely randomized design (CRD) with six treatments and four replicates. Larval mortality was observed at 6, 12, 24, 36, and 72 hours after treatment (HAT) and analyzed using the Kruskal-Wallis test at a significance level of 5% (α = 0.05). The results showed that corrected mortality at 72 HAT ranged from 85–100% across synthetic insecticide treatments, caused mortality in S. frugiperda larvae with symptoms such as decreased feeding activity, paralysis, body color changes, and shriveled death. The combination of emamectin benzoate + chlorfenapyr at the highest consentration caused 100% mortality within 12 HAT, whereas cypermethrin reached complete mortality at 24 HAT. Abamectin exhibited a more gradual increase in mortality up to 72 HAT. Numerically, the combination treatment demonstrated a more rapid mortality response than the single active ingredient treatments. These results indicate that all tested synthetic insecticides were effective against third instar S. frugiperda larvae, although differences in the speed of mortality response were observed among treatments.

Abstract

The sweetpotato weevil (Cylas spp.) is one of the major pests of sweet potato that can reduce both the quality and quantity of yield, as it attacks not only the tubers but also acts as a stem borer. This study aimed to determine the effect of mulch application on the attack intensity of Cylas spp. on purple-fleshed sweet potato (Ipomoea batatas), to examine the distribution pattern of pest populations on tubers and stems, and to analyze the relationship between pest population and the resulting attack intensity. The study was conducted using a Randomized Block Design (RBD) with three treatments, namely control (F0), plastic mulch (F1), and straw mulch (F2), each replicated nine times, resulting in 27 experimental units. The results showed that the application of different types of mulch did not significantly affect the attack intensity of the sweetpotato weevil. Nevertheless, the straw mulch treatment produced the lowest attack intensity at 4.07%, followed by the control at 4.99%, and plastic mulch at 5.13%, with all treatments classified under the mild attack category (intensity below 10%). Cylas populations were found attacking both tubers and stems, with the highest population recorded in the control treatment (10.33 individuals on tubers and 5.00 individuals on stems), followed by straw mulch (4.33 and 2.56 individuals), and the lowest in plastic mulch (3.67 and 0.78 individuals). Pest populations on tubers were consistently higher than on stems, indicating that tubers are the primary target of adult Cylas spp. attack. Correlation analysis revealed a positive relationship between pest population and attack intensity, although classified as weak, with a correlation coefficient (R) of 0.314, indicating that an increase in pest population tends to be followed by an increase in attack intensity, although not consistently strong.

Abstract

This study aims to examine the effect of corporate governance and sustainability disclosure on firm value in the plantation sector in Indonesia. This study employs a quantitative method using secondary data sourced from annual reports, sustainability reports, and financial statements of plantation sector companies listed on the Indonesia Stock Exchange (IDX) during the 2021-2024 period. The sample was selected using a purposive sampling technique. Data analysis was conducted using a panel data regression method with a Random Effect Model (REM) approach, processed through E-Views 12 software. The partial hypothesis testing results reveal that sustainability disclosure has a positive and significant effect on firm value. In contrast, corporate governance, proxied by independent commissioners, does not have a significant effect on firm value. Simultaneously, all independent variables, along with control variables including firm size, profitability, and leverage, significantly affect firm value. The conclusion of this study indicates that investors in the plantation sector respond more positively to corporate transparency regarding economic, social, and environmental information than to the mere presence of independent commissioners

Abstract

ABSTRACT Borer pests are one of the factors that can reduce sweet potato productivity because they cause damage to the stems and tubers. One of the cultivation practices that can be applied to reduce pest infestation is the use of mulch. This study aimed to identify borer pest species and analyze their infestation intensity on the stems and tubers of sweet potato under different mulch treatments. The study was conducted using a one-factor Randomized Complete Block Design (RCBD) with three treatments, namely no mulch (T0), silver-black plastic mulch (T1), and straw mulch (T2), with nine replications. The results showed that three borer pest species were found on sweet potato plants, namely Omphisa anastomosalis, Cylas sp., and Oberea sp. The analysis showed that the different mulch treatments had no significant effect on the infestation intensity of borer pests on either the stems or tubers of sweet potato. Therefore, the use of silver-black plastic mulch and straw mulch tested in this study did not demonstrate effectiveness in reducing borer pest infestation intensity in sweet potato plants. ABSTRAK Serangan hama penggerek merupakan salah satu faktor yang dapat menurunkan produktivitas ubi jalar karena menyebabkan kerusakan pada bagian batang dan umbi. Salah satu upaya budidaya yang dapat dilakukan untuk mengurangi serangan hama adalah penggunaan mulsa. Penelitian ini bertujuan untuk mengidentifikasi jenis hama penggerek serta menganalisis intensitas serangannya pada batang dan umbi ubi jalar pada perlakuan mulsa yang berbeda. Penelitian dilaksanakan menggunakan Rancangan Acak Kelompok (RAK) satu faktor dengan tiga perlakuan, yaitu tanpa mulsa (T0), mulsa plastik hitam perak (T1), dan mulsa jerami (T2), dengan sembilan ulangan. Hasil penelitian menunjukkan bahwa terdapat tiga jenis hama penggerek yang ditemukan pada tanaman ubi jalar, yaitu Omphisa anastomosalis, Cylas sp., dan Oberea sp. Hasil analisis menunjukkan bahwa perlakuan jenis mulsa tidak memberikan pengaruh nyata terhadap intensitas serangan hama penggerek pada batang maupun umbi ubi jalar. Dengan demikian, penggunaan mulsa plastik hitam perak maupun mulsa jerami yang diuji dalam penelitian ini belum menunjukkan efektivitas dalam menekan intensitas serangan hama penggerek pada tanaman ubi jalar.

Abstract

Spodoptera frugiperda (J.E. Smith) is a major invasive pest of maize that causes serious damage and yield losses in various regions of Indonesia, including East Lombok Regency. The utilization of parasitoids as natural enemies is one of the biological control strategies that plays an important role in supporting integrated pest management (IPM). This study aimed to identify larval parasitoid species associated with S. frugiperda and to analyze parasitoid diversity, relative abundance, and parasitism rate in maize fields in Pringgabaya District, East Lombok Regency. The research was conducted from August to December 2025 using a survey method with purposive sampling. Observations were carried out at three maize-growing locations, with five diagonal plots measuring 5 × 5 m established at each location. Collected S. frugiperda larvae were reared in the laboratory until parasitoids emerged and were subsequently identified based on morphological characteristics. The results showed the presence of three types of larval parasitoids associated with S. frugiperda, namely Tachinidae sp., Megaselia scalaris, and one parasitoid that could not be identified. The total parasitism rate was 19.30%, with the highest rate recorded in Apitaik Village (11.42%), followed by Teko Village (5.76%) and North Pringgabaya Village (2.12%). The relatively low parasitoid diversity indicates that the effectiveness of natural biological control against S. frugiperda in the study area remains limited. Therefore, conservation of natural enemies through environmentally friendly cultivation practices is needed to enhance the role of parasitoids in suppressing pest populations in maize agroecosystems.

Abstract

Growing medium height in sack cultivation may alter root-zone space and plant responses, yet its effects on branching and yield components of sweet potato require further investigation. This study aimed to evaluate the responses of branching and yield components of Lato-lato sweet potato to growing medium height in sacks and to analyze the relationships between branch number and yield components. The experiment was conducted from October 2025 to January 2026 in Lingsar, West Lombok, using a 5 × 5 Latin square design with five growing medium heights of 20, 30, 40, 50, and 60 cm, resulting in 25 experimental units. Observed variables included branch number, storage root number, total storage root weight, and average storage root weight. Data were analyzed using analysis of variance at the 5% significance level and Spearman correlation. Growing medium height had no significant effect on branch number (p = 0.056), storage root number (p = 0.621), total storage root weight (p = 0.109), or average storage root weight (p = 0.261). Branch number was not significantly correlated with storage root number (ρ = −0.293; p = 0.155) or total storage root weight (ρ = 0.309; p = 0.133), but showed a significant positive correlation with average storage root weight (ρ = 0.439; p = 0.028). Growing medium heights of 20–60 cm did not significantly alter branching or yield components, while the association between branching and yield was found only for average storage root weight.
