Abstract

Permasalahan perubahan iklim global merupakan isu kebijakan strategis yang menimbulkan dampak negatif pada lingkungan seperti terjadinya kelangkaan air irigasi yang implikasinya berupa terjadinya penurunan produktivitas pasokan pangan dan penurunan tingkat efisiensi air irigasi.  Hal ini menjadi lebih komplek karena terjadi perubahan  pola  dinamika  sosio-kultural  yang secara langsung maupun tidak langsung menentukan karakteristik  dan  arah  layanan  irigasi yang  diharapkan. Penilaian (audit) kinerja fisik dan distribusi belum dirasa cukup untuk menilai kinerja irigasi secara keseluruhan sehingga perlu diketahui  hubungan dinamika sosio-kultural dengan kinerja irigasi.  Tujuan penelitian  : (1) Mengidentifikasi faktor yang menentukan efektifitas dan efisiensi sistem irigasi; (2) Mengevaluasi kinerja irigasi metode LPR/FPR dan metode  FAO/Sosio-kultural  sesuai SNI bidang pengairan. Pendekatan riset non eksperimen dan ekplanatif dengan metode survey,  analisis dilakukan pada aspek fisik dan distribusi serta sosio-kultural irigasi seperti kondisi fisik, keseragaman air, kecukupan air, dan efisensi air irigasi serta persepsi HIPPA/GHIPPA terhadap faktor kinerja  melalui skala likert. Lokasi dilaksanakan pada DI Molek-Kepanjen Malang dengan luasan 3.971 ha. Standar analisis data, standar kepmenPU. Sedangkan persepsi terhadap faktor kinerja irigasi menggunakan skala linkert, Hasil dari penelitian terdapat hubungan antara faktor-faktor penentu efektivitas dan efisiensi serta sosio-kultural irigasi dengan Kinerja Irigasi. Faktor penentu internal (sosio-kultural)  yang paling signifikan menentukan kinerja pengelolaan irigasi adalah indikator Partisipasi menyangkut peningkatan peran dan partisipasi GHIPPA/HIPPA terhadap pengelolaan irigasi. Pendekatan analisis kebutuhan air irigasi metode  RAP-FAO memiliki nilai indek kinerja irigasi yang lebih efektif dan efisien dibanding pendekatan LPR/FPR (eksisting). Kata kunci:  Audit sosio-kultural  irigasi,   HIPPA/GHIPPA, skala likert.

Abstract

This research aims to describe plants diversity having local wisdom value for Ot-Danum Dayak people, Tumbang Payang village and Tumbang Kania village, Central Kalimantan. The result reveals that since a long time ago, Ot-Danum Dayak people truly depend on natural resources to meet various daily needs. The vast majority of subsistence and society's income are form forest plants product. Plant diversity can provide food product for society, can produce various plants to be consumed and also produce alternative income sources, such as exploited for food, medicine, fermentation, tonic, cosmetic, building material and etc. However, the existing plant diversity is endangered since deforestation and forest degradation, and even there are many lesser-known species. Therefore, it needs to quickly find the information about the species to conservation effort, given the existing forest resource has a big potential to be developed and cultured to the species through domestication and providing a genetic resource for hybridization and selection.

Abstract

Water user farmer association (P3A) is an organization closely related to regulation of irrigation water in a tertiary or village plot service area formed by farmers or farmer groups in a democratic village. The role of P3A is to manage irrigation water and water distributors fairly and evenly in tertiary / stronger printing. The research aims to analyze the management of community-based irrigation system by P3A  in Suak Village of Manis Raya Village of Sepauk Subdistrict of Sintang Regency and to Analyze the inhibiting factors in the management of irrigation system. The research was done by descriptive method and qualitative analysis. Data obtained from interviews, literature, and field observations, then analyzed and interpreted by giving conclusions. The results of the research indicate that (1) the institutional aspect, irrigation network in Suak sub village has no institution of water user farmer association (P3A), (2) HR aspect, farmer of Dusun Suak has adequate human resources seen from age, education, social economy and work ability. (3) Aspects of facilities and infrastructure, facilities and infrastructure of farmers in the village of Suak are still limited, farmers have not been able to utilize existing facilities and infrastructure. (4) Aspects of irrigation systems, farmers are still freely flowing water without regulation, irrigation maintenance is done when there is government funding, the main dam leaked for the last two years has not been fixed. Farmers' awareness of irrigation networks is not yet available. The inhibiting factor of irrigation system management is that there is no P3A institution yet, the participation of farmers is limited, the fund is limited. From the results of the research, irrigation management in the village of sweet is still not implemented maximally either from government or from society, seen from condition of irrigation network which often happened accumulation of garbage and weeds. In addition, community participation is still very poor. Irrigation management in the hamlet of Suak has not been well managed by the farmers either in the maintenance of irrigation networks, as well as the distribution of farmers' peat water because there is no P3A organization that regulates irrigation management and water distribution. Irrigation management can be sustainable should the cooperation between stakeholders.Keywords: Farmers’ Participation, Irrigation System Management, P3A

Abstract

Utilization of dry land resources most available in the upper watershed which hilly landform and heavy rainfall. This leads to erosion event and resulting decrease of land productivity. Thus, it needs application of conservation techniques to optimize the utilization of dry land in the upstream watershed. The aims of study are to identify the conservation application on the farm vegetables, to examine the perception of farmers towards conservation farming, and to assess the participation of farmers in conservation farming in the Upper Jeneberang watershed. Research sites in the upstream watershed Jeneberang, Gowa in South Sulawesi. The population is vegetable farming. The respondents did sampling randomly with number 182 farming. Data analysis methods used is descriptive analysis that is equipped with a qualitative analysis that are category and comparison analysis. The results showed the level of farmers' perceptions about the benefits of conservation has been generally high, the benefits to the prevention of erosion (61.54%), soil fertility (58.89%), availability of water (64.84%) and prevention of floods and landslides (67.58 %). The high perception of farmers on the benefits of conservation is not followed by the participation of farmers in conservation farming. This is evident from the participation in counseling following the generally very low (56.59%), participation in the application of generally low conservation (27.47%), while participation in the maintenance has been generally high (31.32%).

Abstract

Assessment of soil fertility status can be done through a soil test approach, but the main problem is the difficulty of predicting the nutrient content in the soil. This requires laboratory testing and takes several times, while the nutrient requirements must be known immediately so that plants can grow ideally. In the last few decades, researchers have been trying to find alternative methods that are fast, innovative, effective, environmentally friendly, and non-destructive to predict nutrient concentrations. One of the technologies that are currently developing rapidly and has the potential to be used to detect/predict the nutrient content is near-infrared reflectance (NIR). Many studies have been conducted and reported related to the application of close-range infrastructure technology, especially for speed and soil quality. This paper discusses several reviews of research in Aceh Province related to the application of NIRS Technology to detect soil fertility. The NIR technique is an analytical technique that is fast and does not damage the sample of the material to be tested. Information on chemicals based on biological reactions after exposure to NIR radiation. Near-infrared light is available in the wavelength range up to 780 nm to 2500 nm or above visible light. When a ray coming from a light source A falls on a biological object, there will be an interaction between the object and the light. The object's location will respond in the form of reflection, absorbance and transmission. The reflection response can be in the form of direct reflection (specular reflectance) which means that light is reflected back by objects, pseudo reflection (diffuse reflectance) where light is first and then reflected. This research about NIR technology, it can solve problems, especially regarding the improvement and evaluation of soil fertility by predicting the right model to measure the nutrient content of the soil.

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

Penelitian yang bersubyek pada petani tradisional Arfak dari Subsuku Hatam telah dilaksanakan di Kampung Syoubri, Kwau dan Mokwam Distrik Warmare Kabupaten Manokwari yang bertujuan mengkaji dan mendeskripsikan tipologi kebun campuran petani Hatam eksisting dan permasalahannya. Penelitian ini merupakan penelitian survei deskriptif yang didesain menggunakan pendekatan kualitatif naturalistik yang dimaksudkan untuk mendeskripsikan secara sistematis, faktual dan akurat terkait fakta-fakta, karakteristik serta hubungan antar fenomena yang diteliti. Metode pengumpulan data yang digunakan adalah primary methods yang menggunakan beberapa teknik sekaligus seperti teknik partisipasi, observasi langsung, wawancara mendalam dan studi literasi/pustaka (Morrisan, 2016). Jumlah sampel ditetapkan sebanyak 5 orang per kampung dan menggunakan teknik sampling bola salju mengingat subyek penelitian bersifat homogen (Yunus, 2010).Variabel yang diamati adalah karakteristik kebun campuran meliputi lama bera, luas lahan, jenis tanaman, cara bercocok tanam, produksi, dan pemasaran. Hasil penelitian menunjukkan bahwa kebun campuran petani tradisional Hatam saat ini termasuk dalam tipologi agroforesti sederhana semi subsisten, yang dicirikan dengan masa bera 2 -5 tahun, terbatasnya jenis tanaman yang ditanam, terdiri dari tanaman hortikultura dan tanaman pangan semusim, tidak menggunakan input kimia, tanpa olah tanah dan pola tanam tidak teratur, produksi terbatas dengan kualitas yang rendah dimana hasil kebun separuh untuk kebutuhan sendiri dan lainnya untuk dijual. Permasalahan utama yang dihadapi antara lain pendapatan rendah dari hasil kebun, meningkatnya kebutuhan ekonomi, rendahnya pengetahuan dan ketrampilan petani karena belum adanya pembinaan yang intens dari Dinas terkait, terbatasnya lahan pertanian potensial yang dapat dikelola, faktor resiko kegagalan panen cukup tinggi akibat bencana alam dan ketiadaan lembaga tataniaga yang membantu pemasaran produk petani.

Abstract

Landuse change are suspected to be one responsible to soil fertility decline on Slamparejo, Jabung, Malang. Efforts done by local farmers to deal with these problems are plantation of P. falcataria trough a reforestation program around 2003-2004. The benefits of the program are still need to be assessed so that this research was done (1) to compare the soil quality between P. falcataria-planted field and no P.falcataria field by the parameters of soil organic matter content and available N, (2) to study the relationship between organic matter input and soil organic matter content and available N, and (3) to identify factors affecting N availability post-P. falcataria plantation.This research used randomized block design with 5 treatments (annual crop field, 3 and 6 years P. falcaria plantation field, agroforestry field with P. falcataria + coffee + talas plantation, and ex-P. falcataria-planted field. Soil were sampled compositely by 3 replication from 0-20 cm depth. Litter were sampled from a 0.5m2 sub-plot of each treatment.Results showed that P. falcataria plantations enhance soil fertility indicated by increased soil organic matter input to 10.6 times (monoculture) and 17.6 times (agroforestry) control, increased soil organic matter content by 1.5 times (monoculture) and 2.3 times (agroforestry) control, increased total N of 1.6 times (monoculture) and 2.4 times (agroforestry) control, increased ammonium by 1.7 times (monoculture) and 3.2 times (agroforestry) control, and increased nitrate by 2.4 times (monoculture) and 3.9 times (agroforestry) control. The increased soil N content of P. falcataria-planted field were caused by higher soil organic inputs compared to those with no P. falcataria plantation. Nitrogen availability affected by soil texture but have no relationship with soil pH. However, agroforestry fields showed higher pH, organic C, total N, and available N than monoculture P. falcataria fields. Measured soil chemical properties showed no significant change by the increase of P. falcataria age, moreover, they declined down towards control on ex-P. falcataria plantation. This indicates that reforestation would only give a temporary soil quality enhancement.Key words: Regreening, Paraserianthes, Agroforestry, Soil organic matter, nitrogen total

Abstract

Mount Merapi is most active volcano and periodically erupted. The erupted materials are soil parent materials which rich of base cations that useful for plant growth. Leaching process was used as alternative approach to study base cations released. Leaching experiment used artificial rain water. The effort to reduce base cations leached and also increase base cations relesed was using chicken manure, leucana litters, and Arachis pintoi that used as cover crop as the treatment of experiment. The leaching experiment simulated 4 years rainfall intensity. After incubation for 96 days (4 years rainfall simulation), addition of chicken maure and leucana litters decreased base cations leached in Mount Merapi pyroclastic materials, except for K+ by 16%. Planting Arachis pintoi decrease base cations leached in Mount Merapi pyroclastic materials by 13% but did not increase base cations released.Key words: pyroclastic, leaching, base cations
