Abstract

Coffee plantation management has an important role in soil quality in order to increase coffee production. Biopore Infiltration Hole with Compost (BIHC) can increase soil available water capacity. In this study, the goal was to improve soil available water capacity in a coffee plantation with the implementation of the BIHC. This study was conducted at PTPN XII Bangelan, Malang, on March - August 2020. A randomized block design with seven treatments and four replications was used. The BIHC consisted of two-hole depths (30 cm and 60 cm) and two types of compost (goat manure and coffee pulp compost). The soil characteristics observed were water retention (pF) and C-organic at soil depths of 0-20, 20-40, and 40-60 cm. The coffee tree observed were number of leaves and chlorophyll content. Data obtained were subjected to analysis of variance (ANOVA) by the F test and Duncan's Multiple Distance Rate  Test (DMRT) at 5% probability, using SPSS program. Results of the study showed that BIHC was able to increase the content of soil C-organic and the available water capacity significantly compared with control treatment. The BIHC implementation could increase soil available water capacity up to 65% at a soil depth of 0-20 cm, up to 60% at a soil depth of 20-40 cm, and up to 51% at a soil depth of 40-60 cm more than the control treatment. The soil available water capacity suggested a significant positive correlation (p≤0.05) with the leaves number of coffee tree and chlorophyll content of leaves.

Abstract

Composting is an alternative way to accelerate decomposition and maturation of residual waste from refining leaves of cajuput to be suitably applied to the soil. The application of Cajuput Waste Compost (CW Compost) is intended to increase the productivity of sandy soil in Indonesian dryland. Compost serves as a soil conditioner that can improve the physical, chemical and biological properties. The study aimed to determine and analyze the role of CW compost in improving the physical quality of sandy soil in two incubation periods. The study used experimental methods, through soil incubation that given CW compost, in a greenhouse with two incubation periods. The experiments used a completely randomized design with 4 levels of CW compost treatment, namely: 0 t/ha (P0), 10 t/ha (P1), 20 t/ha (P2), 30 t/ha (P3). The results showed CW compost had a significant role in improving the physical quality of sandy soil both at 1-month and 4-month incubations. The soil physical quality increased by increasing compost levels and incubation periods, except for the total available water variable which decreased after 4-month incubation. The decrease was allegedly due to the reduction of labile fraction in the soil

Abstract

The biopore infiltration hole with organic material litter can increase the soil capacity to accommodate and store soil moisture. This study was aimed to determine the effect of biopores and organic material litter on soil moisture storage and the relationship of climatic conditions on soil moisture storage. The experiment was carried out on clove plantations on Ternate Island, North Maluku from December 2018 to February 2019. This study used a factorial randomized block design. The first factor was the biopores with a depth of 50 cm and 90 cm, and the second factor was 4 types of organic material litters in the form of nutmeg leaves, clove leaves, Guinea grass leaves and a mixture of clove leaves and Guinea grass. The factors observed were total soil water storage and at depths of 0-20, 20-40, 40-60 and 60-80 cm; organic matter content; C/N ratio and soil total N. Data analysis used the GenStat program with analysis of variance test (ANOVA) and Duncan's Multiple Distance Test. Results of the study showed that evaporation and percolation are climatic factors that affect water loss. Increase in soil water storage at 20-40 cm soil depth of 107.56 mm was yielded by the treatment of 50 cm biopore and Guinea grass leaf litter but it was not significantly different from the 50 cm biopore and clove leaf litter + chicken manure treatment. The treatment of biopore and organic material litter also increased the organic matter and soil total N and decreased the soil C/N ratio, but it did not have a significant effect.

Abstract

A study on the addition of organic matter of different qualities was carried out to improve plant growth on a degraded sandy soil of Bambang Village, Wajak Malang, East Java. Two potential sources of organic matter in Bambang Village are Tithonia diversifolia and sugarcane leaves. This study aimed at elucidating the changes in some chemical properties of a degraded sandy soil of Malang, East Java, and nutrient uptake and growth of maize plants by applying mixtures of Tithonia diversifolia and sugarcane leaves of different quality. Treatments tested in this study were mixtures of Tithonia diversifolia leaves and sugarcane leaves at various proportions (%w/w), i.e. 100% Tithonia diversifolia leaves (T1), 100% sugarcane leaves (T2), 75% Tithonia diversifolia leaves + 25% sugarcane leaves (T3), 50% Tithonia diversifolia leaves + 50% sugarcane leaves (T4); without organic matters (T6), and control, without organic matter and inorganic fertilizers (T7). The results showed that the application of Tithonia diversifolia and sugarcane leaves affected soil pH, soil exchangeable bases, maize growth, and nutrients uptake. Nutrients taken up by maize plants significantly increased with the addition of Tithonia diversifolia leaves, either alone or in combination with sugarcane leaves. The application of 100% sugarcane leaves did not significantly affect maize growth and nutrient uptake.

Abstract

Penelitian dilaksanakan pada titik longsor pewakil di wilayah Perbukitan Malang Selatan. Analisis longsor didasarkan pada kondisi longsor dan tipe penggunaan lahan yang terbagi menjadi tiga yaitu hutan produksi, kebun campuran dan tegalan. Tujuan penelitian adalah mengidentifikasi karakteristik lapisan semi kedap dan kedalaman bidang gelincir tanah melalui estimasi kondisi lapisan semi kedap. Hasil penelitian menunjukkan bahwa lapisan semi kedap yang berpotensi memicu longsor berupa akumulasi liat yang padat dan relatif mampat. Lapisan semi kedap dan komposisi tekstur pada penampang longsor menentukan kedalaman bidang gelincir tanah. Hal ini berkaitan dengan kondisi bidang gelincir tanah. Identifikasi pembentukan bidang gelincir tanah paling dalam ditemukan pada penampang longsor Desa Sempol pada kedalaman 82 cm dengan komposisi lapisan liat semi kedap pada kedalaman 100 cm sedangkan pembentukan bidang gelincir paling dangkal ditemukan pada penampang longsor Desa Telogorejo pada kedalaman 27 cm dengan bentukan kombinasi lapisan liat semi kedap dengan pecahan fragmen batuan gamping pada kedalaman 27-107 cm. Pembentukan bidang gelincir juga ditentukan komposisi laju aliran air dan komposisi tekstur antar lapisan tanah. Semakin halus komposisi tekstur maka laju KHJ akan semakin rendah sehingga estimasi bentukan bidang gelincir tanah dapat terlihat dari perbedaan nilai KHJ antar lapisan tanah. Semakin dalam bentukan bidang gelincir tanah, maka semakin besar volume longsornya.  Volume longsor terbesar ditemukan pada penampang longsor Desa Sempol yaitu 337.5 m3 sedangkan untuk volume longsor terbesar ditemukan di Desa Telogorejo yaitu 17.2 m3. Penelitian dapat disimpulkan bahwa letak lapisan semi kedap pada kawasan Perbukitan Malang Selatan selalu diikuti oleh pembentukan bidang gelincir tanah sehingga berpengaruh terhadap besarnya volume longsor.

Abstract

Laju transpirasi tanaman bervariasi dengan karakter vegetasi, karakter tanah, lingkungan dan budidaya tanaman. Studi ini bertujuan untuk mempelajari perbedaan kadar lengas tanah dan laju transpirasi tanaman pagar, dan pengaruh laju transpirasi tanaman terhadap konduktivitas hidrolik tidak jenuh. Studi ini dilakukan di Daerah Karta, Lampung Utara, Indonesia selama tiga bulan. Studi ini menggunakan Rancangan Petak Terbagi, dengan dua perlakuan petak utama (jenis tanaman pagar) yaitu Peltophorum dassyrachis (P) dan Gliricidia sepium (G). Dua perlakuan (anak petak) adalah jarak tanaman 40 cm (A) dan 120 cm (B). Masing-masing perlakuan ini diulang empat kali.  Pengamatan kadar lengas tanah dilakukan dengan mengkalibrasikan hasil pengukuran Neutron Probe dengan kadar air gravimetrik. Laju transpirasi tanaman dihitung berdasarkan selisih antara kadar lengas tanah pada perlakuan tanaman pagar tanpa perakaran (T) dengan kadar lengas tanah pada perlakuan tanaman pagar dengan perakaran (R). Konduktivitas hidrolik tidak jenuh diukur dengan menggunakan metode Pedo Transfer Functions. Data hasil pengamatan selanjutnya dianalisis menggunakan metode analisis ragam (ANOVA), uji korelasi dan regresi. Hasil penelitian menunjukkan bahwa kadar lengas tanah di bawah G. sepium lebih tinggi dibandingkan dengan P. dassyrachis, kecuali pengamatan hari ke-0 di kedalaman 40-70 cm. Kadar lengas tanah cenderung menurun seiring dengan waktu pengamatan pada semua jenis tanaman pagar dan jarak tanamnya. Laju transpirasi G. sepium lebih tinggi dibandingkan dengan P. dassyrachis pada kedalaman tanah 0-40 cm, sedangkan pada kedalaman 40-60 cm laju transpirasi kedua jenis tanaman pagar tersebut adalah sama. Pada kedalaman tanah 0-20 cm, laju transpirasi tanaman pagar dengan jarak tanam 40 cm lebih tinggi dibandingkan dengan jarak 120 cm. Sedangkan pada kedalaman tanah 20-60 cm, laju transpirasi tanaman pagar dengan jarak 120 cm lebih tinggi dibandingkan dengan jarak tanam 40 cm. Hasil uji korelasi menunjukkan bahwa tidak terdapat korelasi antara laju transpirasi tanaman pagar dengan konduktivitas hidrolik tidak jenuh.Kata Kunci: hedgerow,kadar lengas tanah, konduktivitas hidrolik tidak jenuh, transpirasi

Abstract

The aim of study was to explore the vulnerability of an irrigation system due to climate change by using a resilience index in irrigation areas (D.I.) of Brantas watershed (Molek, Jatikulon, Menturus, and Konto). There were eighty-two water-user farmers’ associations (HIPPA), sixty eight of them were selected as survey targets. The Duckstein and Plate formula was applied to calculate the resilience index of an irrigation area, while the multinomial regression was used to identify the dominant factors of resilience index. This study proved that Molek, Jatikulon, Menturus and Konto irrigation areas (D.I.) were impacted by climate change with different scales of resilience. The resilience index was 100% for Molek Irrigation area, 80% for Jatikulon irrigation area, 50% for Menturus irrigation area, and 33% for Konto irrigation area. Climate change was predicted to cause a decrease of harvested area, in such a way that in the condition of El Niño around 48% in Konto Irrigation Area, 34% in the Menturus Irrigation Area, 28% at the Jatikulon Irrigation Area, and 15% in the Molek Irrigation areas. Nevertheless, in the La-Nina condition, there was no increase of harvested area in the entire irrigation area studied, even, there was a 28% decrease of harvested area in Konto irrigation area, and 6% in Menturus irrigation area. The most powerful threat toward an irrigation system’s sustainability was the environment, followed by physical, social, and economic aspects respectively. The results of this study implicate to the improvement of irrigation management policy, namely to the operational pattern of irrigation system, which uses a resilience index (Ik) as basic measure of irrigation system management out of the K-factor.

Abstract

The ecological feasibility of sago plants is not strong enough to determine sago as a commodity that can be developed in the upstream area. The research objective was to assess the community's perception of the strategy for water of sago land management in Salu Paku sub-watershed, the upper part of Rongkong watershed. The research begins with the socialization of the rainfed sago land water management strategy. The research consisted of two stages (before socialization and after socialization). The results showed that before the socialization, 100% of the community understood that sago land did not need water management, but after socialization, the community understood that sago could be developed in dryland conditions if there was water management. The community previously understood that it was not important to regulate the number of plants in one clump, after receiving additional information, generally, they wanted to regulate the number of sago trees by maintaining two tillers, one weaning plant, and two tillers during the weaning period. phase, and in the tree phase raise one tree plus one wean and two chicks. The public perception of water conservation measures before the socialization was doubtful 100%, after the socialization, the perception increased 95% (willing to make terraces and dead-end trenches), and 5% were still in doubt. Public perception about the addition of organic fertilizer to sago land before the socialization was doubtful 100%, after the socialization, 95% of the people agreed to add organic fertilizer, although 5% still had doubts

Abstract

Land use affects changes in peak discharge so that it has the potential to cause or prevent flooding. Sago has morphological characteristics that have the potential to absorb more water. This study aimed to determine the magnitude of the change in peak discharge in the upstream watershed after sago planting. Observations were made on the three growth phases of sago palms (initial, middle, and mature phases). The research stages included calculating the runoff coefficient value under sago stands at three growth phases. Peak discharge of the existing conditions (settlements, rice fields, mixed gardens, shrubs, sand dunes, forests, and water bodies) was estimated after three scenarios of sago land use. The scenarios consisted of 25% of the land area planted with sago (scenario 1), 50% for scenario 2, and 100% for scenario 3. The data were analyzed quantitatively by comparing peak discharge in the existing conditions with scenario results. The results showed that the peak discharge in the existing conditions was 52.36 m3 hour-1. Peak discharge in the initial phase of scenario 1 was 18.94 m3 hour-1, scenario 2 was 37.88 m3 hour-1, and scenario 3 was 75.77 m3 hour-1. Peak discharge in the middle phase of scenario 1 was 19.01 m3 hour-1, scenario 2 was 38.02 m3 hour-1, and scenario 3 was 76.04 m3 hour-1. Peak discharge in the mature phase of scenario 1 was 6.38 m3 hour, scenario 2 was 12.76 m3 hour-1, and scenario 3 was 26.55 m3 hour-1. The peak discharge in the upstream watershed decreased after the scenarios with the use of sago land for all growth phases, except for scenario 3 of the initial and middle phases.

Abstract

Coffee plants are one of the plantation crops that are widely cultivated by smallholders in Sumbermanjing Wetan District. The problem that is often experienced by coffee farmers is the decline in coffee production due to climate. The adverse effect of climate change can be overcome through mitigation by implementing shade plants. The saturated hydraulic conductivity of the soil is defined as the movement of water in a porous medium in a saturated state. By measuring hydraulic conductivity, it can determine the ability of the soil to conduct water and see the movement of water in the soil. The highest value of saturated hydraulic conductivity at a depth of 0-20 cm was found in coffee plants with sengon shade at 31.02 cm hour-1. The highest value of saturated hydraulic conductivity at a depth of 20-40 cm was found in coffee plants with the shade of Dadap plants, which was 56.67 cm hour-1, included in the fast category. Differences in shade and soil depth in coffee fields affect the value of the saturated hydraulic conductivity. There is a relationship between several physical properties of the soil and the saturated hydraulic conductivity of the soil. The physical properties of the soil affect the saturated hydraulic conductivity of the soil.
