Abstract

Perbanyakan kopi robusta (Coffea canephora) dengan metode stek sering terkendala pada pertumbuhan akar dan tunas daun. Pemberian Indole-3-Butyric Acid (IBA) diharapkan dapat mengatasi masalah pertumbuhan akar dan tunas pada stek batang. Tujuan penelitian ini adalah untuk menemukan konsentrasi IBA yang tepat terhadap pertumbuhan akar dan tunas daun stek kopi robusta. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) nonfaktorial dengan perlakuan konsentrasi IBA terdiri atas 0 ppm, 50 ppm, 100 ppm, 150 ppm, 200 ppm, 250 ppm, dan 300 ppm, dan diulang 4 kali. Parameter pengamatan meliputi panjang akar, jumlah daun, bobot basah dan kering berangkasan stek batang. Hasil penelitian menunjukkan bahwa pemberian IBA 150 ppm pada stek batang kopi robusta mampu menghasilkan panjang akar terbaik. Namun demikian, seluruh konsentrasi IBA yang diujikan belum mampu meningkatkan jumlah daun, berat berangkasan basah, dan berat berangkasan kering stek batang kopi robusta.Kata kunci: Indole Butyric Acid, kopi robusta, stek batang,

Abstract

Penurunan kandungan karbon organik dalam tanah sering kali menjadi dampak dari penerapan praktik budidaya yang kurang ramah lingkungan di agroekosistem salah satunya adalah lahan perkebunan. Penelitian ini bertujuan untuk mengidentifikasi praktik budidaya yang diterapkan di berbagai perkebunan di Sub DAS Tuntang, mengetahui kandungan karbon organik tanah, serta menganalisis hubungan antara praktik budidaya dengan kandungan karbon organik tanah. Penelitian dilakukan melalui survei lapangan di 41 titik sampel menggunakan metode stratified random sampling, disertai observasi agroekosistem dan wawancara petani. Analisis hubungan antara praktik budidaya dengan kandungan SOC dilakukan menggunakan Fisher's Exact Test. Hasil menunjukkan bahwa sebagian besar praktik budidaya seperti pemupukan, pola tanam, pengolahan tanah, penutup tanah, dan pengendalian hama tidak memiliki hubungan signifikan dengan kandungan karbon organik tanah. Namun, pengelolaan sisa tanaman dengan membiarkannya terurai secara alami terbukti memiliki hubungan signifikan dalam meningkatkan kandungan karbon organik tanah. Temuan ini menunjukkan bahwa retensi residu tanaman merupakan strategi yang efektif untuk memperbaiki kualitas tanah sekaligus mendukung upaya mitigasi perubahan iklim di lahan perkebunan.

Abstract

Irrigated rice fields with flooded cultivation systems tend to produce more carbon than they sequester, as the vegetation is dominated solely by rice plants. In contrast, plantation agroecosystems, which contain a more diverse range of plant species, have greater potential for carbon sequestration due to their higher biomass. This study aimed to analyze the relationship between plant biodiversity and vegetation carbon sequestration in irrigated rice fields and plantation areas within the Upper Tuntang Sub-watershed, at Semarang Regency, Central Java. The research involved 48 sample plots, consisting of 8 irrigated rice field sites and 40 plantation sites, selected based on carbon potential using NDVI data. Research stages included establishing sampling plots, plant species identification, and measuring both biodiversity and vegetation carbon sequestration. Results showed that the biodiversity index in irrigated rice fields fell into the low category, as rice was the only dominant species. In contrast, the plantation exhibited medium biodiversity indices due to the presence of more varied plant species. Carbon sequestration was highest (7,68) at point 5 and lowest (0,01) at point 7 in irrigated rice fields, while in plantation it was highest (230,00) at point 37 and lowest (0,01) at point 39. To assess the relationship between biodiversity and carbon sequestration, the plots were classified into three vegetation structure types: (1) understory plants, (2) understory plants and trees, and (3) understory plants, trees, and shrubs. A significant relationship between biodiversity and carbon sequestration was observed in plots containing both understory plants and trees with sig. value (2-tailed) of 0,047. However, no significant relationship was found in plots dominated solely by understory vegetation with sig. value (2-tailed) of 0,897, nor in plots containing understory, trees, and shrubs with sig. value (2-tailed) of 0,255. The research can serve as a basis for sustainable agroecosystem management, as it shows that increasing plant biodiversity can contribute significantly to increased vegetation carbon sequestration in the Upper Tuntang Sub-Watershed. Keywords: biodiversity, carbon sequenstration, plantation, rice field

Abstract

The yellow leaf curl (YLC) disease is one of plant disease generally found in chili pepper. The aim of the research was to know various concentrations of lime juice and synthetic citric acids to protect chili pepper (Capsicum frutescens L.) against YLC disease. The research used a randomized completely block design using seven treatments and three replications. The treatments tested were spraying lime juice of 0.1%, 0.2%, and 0.3% volume per volume (v/v); citric acid solution of 0.1%, 0.2%, and 0.3 % weight per volume (w/v). Control was used water only. The data result were analyzed using the honestly significant different test at the 95% confidence level. The treatment of both lime juice and citric acid solutions 0.2% and 0.3% could decreased whitefly population on chili pepper compared with control. The lime juice and citric acid solutions 0.3% was able to reduce the incidence and intensity of YLC disease. Lime juice and citric acid solution of 0.2% and 0.3% increased fruit numbers and fruit weights compared with control. The lower whitefly population decreased disease incidence of YLC (with regression Y = 5.7505x – 48.029). Intensity of YLC disease decreased fruit numbers and fruit weight (correlation value of -0.949 and -0.912). Keywords:  Citric acid, Chili pepper, Gemini virus diseases, Whitefly.

Abstract

The village of Cukilan, Semarang Regency, Indonesia, is predominantly utilized for agricultural purposes, facilitated by its high rainfall suitable for various crops. Despite the benefits it provides to farmers, the elevated rainfall also poses natural disaster risks, particularly landslides, which can adversely affect surrounding communities. This study aims to map landslide potentials and evaluate their impacts on the agricultural sector in the Cukilan Village, Semarang Regency. The research methodology encompasses a literature review focusing on landslide potential estimation and field survey. The literature review aims to obtain landslide potential distribution maps compiled by DVMBG, considering rainfall, slope, geology, land use, and soil types. Field surveys validate conditions based on landslide potential estimations, involving random soil sampling and analyzing parameters like permeability, texture, bulk density, depth, and surface density. The research findings reveal the impact of landslide potential on the agricultural sector and the mapping of landslide potential areas in Cukilan Village, depicting various risk levels: very high (0.71% of total area, covering 5 ha), high (13.24%, 93 ha), moderate (56.55%, 397 ha), and low (29.48%, 207 ha). Based on these findings, it is evident that managing landslide disaster risks in agricultural development in the area is crucial, including the implementation of safer land use planning and appropriate mitigation strategies.

Abstract

Paddy (Oryza sativa L.) is a staple food crop in Indonesia that requires more water compared to other annual crops. Cultivating paddy in rainfed areas necessitates effective water management to prevent crop failure, making it essential to calculate water balance, planting patterns, and planting calendars. This study aims to analyze the water balance in relation to planting patterns and calendars based on water availability in the field. The research was conducted in Cukilan Village, Semarang Regency, Indonesia. A descriptive quantitative method using Cropwat 8.0 was employed to determine water balance, planting patterns, and planting calendars. The results indicate that from November to April, there is a water surplus, while from May to October, there is a water deficit. Planting can be conducted once per growing season with two possible periods: November-March or December-April. During Period I (November-March), the water requirement is 640.7 mm with effective rainfall of 1031.2 mm. In Period II (December-April), the water requirement is 638 mm with effective rainfall of 935.7 mm. Planting should begin in November or December, with harvest in March or April. From May to October, the land remains fallow due to insufficient water availability. These findings are valuable for enhancing the effectiveness of paddy cultivation in rainfed areas, assisting farmers with planting planning, and minimizing the risk of crop failure due to water scarcity.

Abstract

Jeruk Village, Selo Subdistrict, Boyolali Regency, is a highland agricultural area facing challenges such as sloping land erosion, low conservation knowledge, limited climate adaptation, and weak bargaining power of farmers. The Community Empowerment Program by Students (PMM) through Community Service Program (KKN) was implemented to empower the Bangun Tani 2 and Tani Mulyo 2 Farmer Groups by involving 32 Agrotechnology and Agribusiness students from Satya Wacana Christian University in September–October 2025. Activities included socialization, environmentally friendly technology training, mentoring, soil block making, biopesticide and biofertilizer production, education on sloping land conservation using terraced models, as well as post-harvest training and digital marketing. The evaluation showed an increase in farmers' understanding and skills based on pre-test and post-test scores. This program enhances farmers' independence, reduces dependence on external inputs, promotes product value addition, and expands market access through digital platforms, thereby potentially becoming a sustainable empowerment model for highland regions.
