Abstract

Title : Paddy Soil Quality Management Modeling in District of Jatipuro, Karanganyar Regency. The intensive paddy soil management were known caused the soil degradation, thus the proper paddy soil quality management was needed to maintain the sustainability of soil function. The aim of the research was built a model that can be used as the reference of paddy soil quality management in district of Jatipuro, Karanganyar regency. The research was executed on October 2008 until February 2009. The research was descriptive explorative, carried out by collecting secondary data for model building and getting sample based on random sampling method at paddy soil in each Soil Map Unit (SMU), laboratory analysis for each selected soil quality indicator, and field observation for model validation. The results showed that the builded model: SQi = 0,414 + 0,363 pH, can be used as the reference of paddy soil quality management in district of Jatipuro. Based on the model then the recommendation of paddy soil quality management could be determined, through increasing pH by submerged the soil and delay the rice planting about 2 weeks after flooding. Keywords: model, paddy soil quality, district of Jatipuro

Abstract

Tafsir of the Qur’an is defined as a scientific discipline that is very important for understanding the teachings of the Islamic religion. In this context, methodological approaches play a crucial role in the process of interpreting sacred texts. This article has the vision to explore various exegetical methods applied in the context of the study of Al-Qur’an exegesis. Through a comprehensive literature review, this article examines the importance of selecting the appropriate interpretation method according to the context of the text and the purpose of interpretation. Various approaches such as linguistic interpretation, historical interpretation, and contextual interpretation are explored to enrich understanding of sacred texts. In addition, this article also discusses the implications of using certain interpretive methods in the contemporary context and offers suggestions for the development of more inclusive and diverse interpretive methodologies. It is hoped that this article can contribute maximally to efforts to understand the importance of methodological approaches in the interpretation of the Al-Qur’an and become a basis for further research in this field.

Abstract

The need for halal status and product safety has led to the emergence of the Halal Product Guarantee Act (JPH Law). With the JPH Law, not only food and beverages must be halal certified, but also non-food and beverage products, including cosmetic products and used goods. The purpose of this study is to find out how the relationship between religiosity and halal labeling on purchasing decisions for non-food and beverage products, specifically cosmetic products and used goods. This research is a quantitative study with a total sample of 140 people with data collection using a questionnaire. Data analysis used multiple correlation analysis test, partial test (t test), simultaneous test (f test), and coefficient of determination test (R2 test). The results showed that the religiosity variable had a positive and significant relation on purchasing decisions and the halal labeling variable also had a positive and significant relation. While the test results of the coefficient of determination (R2) are at a value of 55.7% meaning that the variable religiosity and halal labeling contribute to 55.7% of the decision to purchase non-food and beverage products.

Abstract

Coastal areas and small islands in Indonesia, reaching approximately 17,000 islands, will be directly affected by increasing sea levels, seawater intrusion, and salinization. This paper provides insight into salinity and its effect to plant, saline-tolerant animal feed crops' characteristics, adaptation mechanisms, and some proposed strategies to deal with salinity issues. This research was conducted through literature study and data were analyzed descriptively. Salinity affects the photosynthesis process, thereby decreasing the net Photosynthetic Rate (Pn), the stomatal aperture, Fv/Fm (efficient quantum), and quantum yield (light intensity/rate of photosynthesis). Salt-stressed plants can be seen from the severity by measuring the levels of Cl and Na in the roots, leaves, and chlorophyll. Plant tolerance to salinity is divided into two groups: glycophytes that are tolerant of low salt levels and halophytes that are tolerant of high salts. Salinity inhibits cell enlargement and division, increases plant mass, and increases protein and nucleic acid production. The plant adapts to saline stress, including osmotic adjustment, stress protein, free radical oxidative species (ROS) removal, ABA synthesis, and cross-adaptation. Increasing the productivity of animal feed in saline areas could be achieved in various ways by modifying water, land, chemical and biological properties, and farmer habits.

Abstract

ABSTRACTMelon (Cucumis melo L.), one of the high-value fruits, has been started to expand by farmers but the heterogeneity in quality may constrain the development. This study aimed to improve the quality of melon in quartz-sand soil (Quartzipsamments). A field experiment based on the split-plot design was conducted on April to June 2016 in Kotawaringin Timur Regency, Central Kalimantan Province, using two factors comprising melon varieties and on-productive-stage fertilization. The varieties consist of Rio F1 (V1), Action 434 F1 (V2), Madesta F1 (V3), Dewo F1 (V4), Gracia F1 (V5), and Okasa F1 (V6). While four fertilization packages which have different dosage on each were tested, including control (P0), low (P2), medium (P3), and high (P3). The result indicated that either varieties or fertilizing significantly affected growth, yield, and the quality of melon. There was a significant interaction between varieties and fertilizing toward yield and quality. Madesta F1 is the only varieties which showed positive response along with increasing fertilizer dosage, and the highest weight (4.55 kg) occurred on the high fertilizing level (P3). While in regard to sweetness level, Rio F1 showed a positive response until medium fertilizing dosage (P2) and resulted in the highest sweetness level by 13.05 oBrix but decreased on the higher dosage (P3). The fruit weight slightly-negative correlated with total sweetness level where the increase in weight may reduce the sweetness level.Keywords: lowland, quartz sand, sweetness levelABSTRAKMelon (Cucumis melo L.) sebagai salah satu komoditas bernilai ekonomis tinggi mulai dikembangkan banyak petani, namun terkendala dengan kualitas buah yang beragam. Penelitian ini bertujuan untuk meningkatkan mutu buah melon di tanah pasir kuarsa (Quartzipsamment). Percobaan lapangan dengan Rancangan Petak Terbagi dilakukan pada bulan April hingga Juni 2016 di Kabupaten Kotawaringin Timur, Provinsi Kalimantan Tengah, dengan menggunakan dua faktor, yaitu varietas dan dosis pemupukan pada fase produktif. Faktor varietas terdiri atas: Rio F1 (V1), Action 434 F1 (V2), Madesta F1 (V3), Dewo F1 (V4), Gracia F1 (V5), dan Okasa F1 (V6). Sedangkan faktor pemupukan pada fase produktif terdiri atas: kontrol (P0), rendah (P2), sedang (P3), dan tinggi (P3). Hasil penelitian menunjukkan bahwa faktor varietas maupun pemupukan berpengaruh terhadap peubah pertumbuhan, hasil, maupun kualitas. Terdapat interaksi yang nyata antara varietas dan pemupukan terhadap peubah hasil maupun kualitas buah. Madesta F1 adalah satu-satunya varietas yang menunjukkan respon positif dengan meningkatnya dosis pemupukan, dengan bobot buah tertinggi sebesar 4.55 kg dicapai pada perlakuan dosis tinggi (P3). Untuk kemanisan buah, varietas Rio F1 menunjukan respon positif dengan adanya peningkatan dosis hingga dosis sedang (P2) dengan nilai kemanisan tertinggi di antara yang lain (13.05 oBrix), namun menurun pada dosis yang lebih tinggi (P3). Bobot buah berkorelasi negatif yang tidak terlalu erat dengan tingkat kemanisan total buah, semakin tinggi bobot cenderung menurunkan tingkat kemanisan buah.Kata kunci: dataran rendah, pasir kuarsa, tingkat kemanisan
