Abstract

The quality of acidic soil is determined by organic C content produced from rice straw biochar in agriculture. In this context, liquid extract from Kappapychus alvarezii (K-sap) is used as a biochar enrichment agent. Therefore, this research aimed to (i) analyze the character of K-sap enriched rice straw biochar with different volumes, as well as (ii) evaluate the impact on soil water holding capacity, size class distribution, aggregate stability index, respiration rate, and acidic soil chemical characters. The treatment tested was the volume of K-sap kg-1 biochar, namely (i) without biochar, (ii) 0 mL, (iii) 500 mL, (iv) 1,000 mL, and (v) 1,500 mL. Each treatment was repeated three times and placed according to a randomized block design procedure. The area covered by K-sap, pore size, and amorphous degree increased while the pore volume of the biochar surface decreased. The addition of 1,000 mL of K-sap kg-1 biochar released a new peak number associated with the aliphatic and aromatic groups. The K-sap enriched biochar increased the proportion of soil aggregate size of 1-2 mm, water holding capacity, carbon storage, pH, total N, available P and K, exchangeable base cations as well as base saturation. Meanwhile, the concentration of Al3+ and H+ were decreased in the acidic soil solution. The results showed that the performance of rice straw biochar, K-sap volumes, soil chemical quality, water holding capacity, and ability to store carbon of the acidic soil was improved by adding K-sap volume.

Abstract

Climate change has caused rainfall anomalies that have an impact on decreasing the productivity of clove plants (Syzygium aromaticum). This study aims to analyze extreme rainfall anomalies in North Buton Regency and Kolaka Regency, assess its impact on the productivity of clove plants (Syzygium aromaticum), and formulate management strategies that can be applied to increase crop yields. The method used is a quantitative descriptive approach with linear regression analysis to determine the relationship between rainfall and clove productivity. The research population is clove farmers in North Buton Regency and Kolaka Regency, with a sample of three farmers in each village where the research is located. Rainfall data was obtained from the Betoambari Bau-Bau Meteorological Station and the Sangia Nibandera Kolaka Meteorological Station during the 2009–2023 period, while clove crop productivity data was obtained from farmer surveys and reports from the Central Statistics Agency. The results of the study show that North Buton Regency has an average annual rainfall of 1,971 mm with slightly wet climate characteristics (Type C), while Kolaka Regency has an average annual rainfall of 1,973 mm with wet climate characteristics (Type B). Based on the evaluation of the suitability of the rainfall land, it is included in the S1 category (very suitable). Regression analysis showed that rainfall had a less significant relationship with the productivity of clove plants. The results of the regression analysis showed that the determination coefficient (R2) of North Buton Regency was 12.59% and Kolaka Regency was 14.21%. Recommended management strategies to deal with rainfall anomalies in Kolaka Regency include improving drainage systems, soil management and conservation, and environmental sanitation. Meanwhile, in North Buton Regency, it includes the provision of irrigation, the use of mulch and the provision of organic matter.

Abstract

Ketersediaan air sangat berperan dalam siklus hidrologi lingkungan, dimana dalam konsepnya menyatakan jumlah air disuatu luasan tertentu dipermukaan bumi dipengaruhi oleh besarnya air yang masuk (input) dan keluar (output) pada jangka waktu tertentu. Ketidakseimbangan air dapat menyebabkan terjadinya kelebihan (surplus) dan defisit (kekurangan air) dan dapat berdampak pada berbagai sektor, salah satunya di sektor pertanian tanaman pangan yakni terjadinya pergeseran musim dan perubahan pola tanam. Dampak tersebut dapat diminimalisir bila dilakukan pengelolaan yang baik terhadap lahan dan lingkungannya yakni melalui perhitungan kondisi neraca air dalam suatu wilayah. Penelitian ini bertujuan untuk (1) menganalisis sebaran spasial neraca air lahan di wilayah hujan tipe D, (2) menetapkan Waktu dan Pola Tanam berdasarkan Neraca Air lahan Padi dan Palawija di wilayah hujan tipe D. Penelitian ini menggunakan metode survei dan analisis perhitungan neraca air. Hasil penelitian menunjukkan bahwa surplus air di wilayah Kecamatan Palangga dan Baito memiliki periode surplus 8 bulan dengan nilai 192, 40 mm/bulan yang terjadi pada bulan Juni dan terendah 2,04 mm/bulan yang sebarannya meliputi semua titik pengambilan sampel adapun secara administrasi meliputi desa Kiaea, Watudemba, Watumerembe, Wawonggura, Eewa, Onembute, Anggondara, Mekar Sari, Wawouru, Aosole, Sanggi-sanggi, Palangga, Tolihe, Sambahule, Matabubu, Mekarjaya, Wonua Raya, Ahuangguluri, Amasara, Wawouru, Mekarsari, Anggondara, Aosole, Eewa dan Onembute. Defisit air di wilayah Kecamatan Palangga dan Baito memiliki periode 4 bulan dengan periode tertinggi pada bulan Juni yakni 58,59 mm/bulan di titik 6 dan terendah pada bulan Februari dengan nilai 4,68 mm/bulan di titik 2. Wilayah Kecamatan Palangga dan Baito memiliki pola tanam jagung+kacang hijau-padi sawah-bero/sayuran; kedelai/padi sawah-bero/sayuran; jagung+kacang tanah-padi sawah-bero/rumput pakan.
