Abstract
Climate change has significantly impacted human history and evolution, making paddy a vulnerable commodity. Historically, humans have been able to adapt to the changing climate, but the long-term effects can inhibit growth and reduce agricultural production. Adaptation strategies can help reduce the effects of climate change and increase benefits, but there is still room for improvement. This study was conducted in Aceh Besar and Aceh Utara Districts. This study focuses on how households that raise paddy are affected by climate change. Purposive sampling was used as the sampling strategy in this study. This research uses a quantitative and qualitative approach. This study uses Livelihood Index analysis (LVI). The research results show that the vulnerability of paddy farming households in North Aceh is more vulnerable to climate change compared to Aceh Besar because the vulnerability value of paddy farming households in Aceh Besar is 0.44 and North Aceh is 0.45. The impact of climate change in Aceh Besar and North Aceh Regencies is that droughts occur more frequently.

Abstract
Black pepper (Piper nigrum L.) is an important agricultural crop in Indonesia. However, black pepper production in Indonesia is limited by plant pathogen infection, especially Phytophthora capsici, which causes Foot Rot in pepper plants. This pathogen contributes to a high decline in black pepper productivity. This study aims to determine the proper media composition for P. capsici growth based on the mycelial growth, viability, sporulation, and virulence of P. capsici on pepper leaves. The media used in this study were potato dextrose agar (PDA), martin agar (MA), carrot agar (CA), water agar (WA), corn meal agar (CMA), soil extract agar (SEA), and vegetable 8 (V8). The results showed that CMA media was the most optimal medium for P. capsici growth, as indicated by the size of the mycelium with a diameter of 8.00 cm on the fifth day after inoculation. The viability of mycelium of P. capsici was best found on PDA, CMA, and V8 media. Meanwhile, the optimum sporulation and virulence of P. capsici occurred on SEA media, characterized by zoospore production of 5.42x106/ml and symptom areas on leaves of 18.61 cm2 and 16.69 cm2.

Authors: Fhonna F A , Jayanegara A , Samadi  
Published: February 2024

Abstract
Integrating various studies with statistical methods can be used by applying a meta-analysis method. The objective of this meta-analysis was to evaluate the effect of coffee pulp as ruminant feed on in vitro digestibility and rumen fermentation characteristics. The database was developed from six related articles containing 25 studies, collected from Scopus and Google Scholar. The parameters integrated were in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD), pH value, total volatile fatty acids (VFA), NH3 and total protozoa. The data were analyzed using a mixed model methodology. The level of coffee pulp was considered as a fixed factor and the different studies as a random effect. The results revealed that coffee pulp addition had a significant quadratic effect to enhance IVDMD (P<0.01) and a significant linear effect to decrease total VFA (P<0.05). However, coffee pulp addition did not significantly affect (P>0.05) on IVOMD, pH, NH3 and total protozoa. In conclusion, coffee pulp can be used as an alternative feedstuff due to its good digestibility in the rumen. Nevertheless, it should be applied in the right amount to avoid negative effects on animal performance.

Abstract
The purpose of the study is to investigate the effect of fermented feed containing black soldier fly and azolla meal on egg production and egg clutch. The research material used 20 female hybrid chickens and local feed ingredients. The research method was conducted experimentally using a Complete Randomized (RAL) with five (5) treatments and four (4) replications respectively. The feed treatments were P0 (100% feed control), P1 (90% basal feed + 5% black soldier fly + 5% azolla), P2 (85% basal feed + 5% black soldier fly + 10% azolla), P3 (85% basal feed + 10% black soldier fly + 5% azolla), P4 (80% basal feed + 10% black soldier fly + 10% azolla). The observed parameters included egg production, egg clutch, eggshell color, and thickness. The data obtained were analyzed using Analysis of Variance (ANOVA). The study found no significant effect on egg production, egg clutch, shell color, and thickness when feeding fermented black soldier fly and azolla at different levels. It was concluded that fermented feed containing 5-10% black soldier fly and 5-10% azolla did not negatively affect egg production and egg clutch in hybrid chickens.

Abstract
Specific Antibody Negative (SAN) laying hens are chickens that have been raised from eggs with a history of negative Avian Influenza (AI) antibody results and negative antigen tests. This research aims to determine the effect of adding organic mineral premix to feed on the SAN performance of laying hens. This study used 72 laying hens aged 43 weeks which were divided into three treatment groups. Each treatment was repeated three times, each consisting of eight chickens, and kept for 35 days. The treatments given consisted of commercial feed without the addition of mineral premix as a control, commercial feed with the addition of 0.25% mineral premix, and commercial feed with the addition of 0.50% mineral premix. The parameters observed were egg production, feed consumption, feed conversion ratio and AI subtype H5 antibody titer results. The data analysis used was a one-way completely randomized design. The results of the study showed that giving mineral premix feed up to 0.50% did not affect the performance of SAN laying hens, so that the addition of mineral premix in feed up to 0.50% has not been able to increase the egg production of SAN hens, but is still able to produce eggs that are suitable as a medium viral AI H5N1.

Abstract
Shade-grown coffee, incorporated in an agroforestry system, is a common practice of coffee plantations in Aceh Tengah Regency, Aceh Province, Indonesia. Coffee is grown under the shade of a canopy of surrounding trees. Shade trees reduce excessive light and provide a home for various predatory animals, including predatory ants. Some growers plant a dense population of shade trees, while others plant less shade trees. A study to investigate the diversity of ants and their abundance in different densities of shade trees has been conducted from April until August 2023. Ants were sampled from coffee trees (arboreal ants) in two coffee plantations with dense populations of shade trees and two plantations with sparse shade trees. We found 13 ant species in both categories of plantations (combined). All ant species were found in sparsely shaded coffee plantations, and only five were recorded from densely shaded plantations. However, the abundance of ants was much higher in densely shaded plantations than in sparsely shaded plantations. The ant genera Technomyrmex and Componatus were the dominant ants found in sparsely shaded plantations, while the dominant ants in densely shaded plantations were the genera Componatus and Crematogaster. These ants are known as general predators and potentially are predators of coffee berry borer (CBB), a significant pest in the area. This research has shown how different densities of shade trees in coffee plantations affected the ant fauna, which could be used as a basis for ant conservation to increase their ecosystem service as predators.

Abstract
The high persistence of insecticides in soil and their toxicity to farmers and agricultural land are serious problems with insecticide application. This study was to identify and characterize insecticide residues on Inceptisol in the center of horticultural production, Banuhampu Agam West Sumatra. The determination of soil samples was carried out by purposive random sampling with a quantitative survey method. Sample testing using randomized completely block design (RCBD) with four slope levels and three points of sampling : 0-8%; 8-15%; 15-25%, and 25-45% in fields at a depth of 0-20 cm and forests (25-45% slope) as control. Insecticide residues on Inceptisol in the central of horticultural production, Banuhampu Agam West Sumatra, identified as many as 5 types, namely: Cypermethrin [C22H19Cl2NO3]; Permethrin [C21H20Cl2O3]; Profenofos [C11H15BrClO3PS]; Phenthoate [C12H17O4PS2], and Diazinon [C12H21N2O3PS]. Cypermethrin was the most highly contaminated insecticide residue found in soil at 0.1 mg kg−1 and is a pyrethroid insecticide. The effect of slope level was not significant on the identification of the number of active ingredients and total insecticide residue concentration. However, the highest number of active ingredients on 0-8% and 25-45% slope each amounted to 3 units, while the highest total concentration of insecticide residues on 0-8% slope amounted to 0.499 mg kg−1.

Abstract

Pogostemon cablin Benth. (Lamiaceae) is the source of patchouli essential oil, which is an important and unique commodity in the fragrance industry. Patchouli plants are also cultivated on inceptisol with low nutrient content and CEC exchange. The use of mycorrhiza is expected to increase nutrient absorption, and plant performance of patchouli. This research is divided into 2 phases, namely the seedling and post-seedling phases. This study applies a Randomized Block Design (RBD) with 3 x 3 factorial and 3 replications. The observed factors were genus mycorrhizae; namely M1 (Glomus mossae), M2 (Gigaspora cf gigantea), and M3 (Glomus mossae + Gigaspora cf gigantea); and mycorrhizal dose; namely D1 (5 g), D2 (10 g), and D3 (15 g). Data were subjected to analysis of ANOVA using SPSS ver. 21.0 with Tukey’s test. In the seedling and post-seedling phases, the initiation of Glomus mossae had a significant impact on the growth of patchouli and mycorrhiza colonization. The best mycorrhizae dose is 5g which has a significant effect on the number of leaves at 135 and 150 DAP. The interaction of Glomus mossae at a dose of 10 g mycorrhizae has a significant effect on the stem diameter 135 and 150 DAP.
