<p><strong>Sri Gemilang Coconut Variety for Tidal Area</strong></p><p>Indonesia has a tidal swampy area of about 33.4 million hectares, from which + 20 million hectares could be cultivated as a coconut plantation. If it is used optimally, the area could play an important role in supporting the national food security. Several technologies have been produced and applied, and the use of adaptive varieties in tidal land, can improve and enhance the productivity of the land. The availability of superior tall coconut varieties to meet the required coconut seeds for coconut development program is still limited. All of the coconut high yielding varieties launched by the Minister of Agriculture are suitable for dry land only, and not for tidal one. Sri Gemilang, a coconut variety grown in tidal land in Parit Sialang Krubuk, Hidayah Village, Pelangiran District, Indragiri Hilir, Riau Province was evaluated from 2012 to 2016. Observations showed that the production of frutis and copra were relatively stable, averaging above 3.0 tons of copra/ha/year. Sri Gemilang variety with a potential endosperm weight of about 518 g/nut was selected as palms for superior seed sources. Weight of nuts decreased to about 433 g/nut during observation in 2016, after long dry season. However, it was still higher than the control varieties, DTA (371 g/nut) and DMT (366 g/nut) grown on the same tidal land. If the weight of coconut meat is converted to the production of copra/ha, it can reach &gt; 3.0 tons of copra/ha/year, while DTA and DMT grown on tidal land was only 1.6 tons and 1.56 tons of copra/ha/year, respectively. The low weight of endosperm of DTA and DMT is presumably because both varieties which typically grow well on dry land, less adaptable on tidal land.</p><p>ABSTRAK</p><p><br />Indonesia memiliki lahan rawa pasang surut 33,4 juta hektar, sekitar 20 juta hektar dapat diusahakan sebagai perkebunan kelapa. Jika dimanfaatkan secara optimal akan berperan penting dalam mendukung swasembada dan ketahanan pangan nasional. Beberapa teknologi telah dihasilkan dan diterapkan, penggunaan varietas adaptif di lahan pasang surut, dapat memperbaiki dan meningkatkan produktivitas lahan. Jenis kelapa Dalam unggul yang tersedia masih sangat terbatas sehingga belum dapat memenuhi kebutuhan benih untuk program pengembangan kelapa. Varietas unggul kelapa yang telah dilepas oleh Menteri Pertanian, semuanya memiliki habitat pada lahan kering, sedangkan habitat pada lahan pasang surut belum ada. Kelapa Dalam Sri Gemilang tumbuh di lahan pasang surut, yaitu di Parit Sialang Krubuk, Desa Hidayah, Kecamatan Pelangiran, Kabupaten Indragiri Hilir, Provinsi Riau. Hasil penelitian tahun 2012 hingga 2016, menunjukkan bahwa produksi buah kelapa dan kopra relatif stabil, yaitu rata-rata di atas 3,0 ton kopra/ha/tahun. Pada varietas kelapa Sri Gemilang dilakukan pemilihan Pohon Induk dengan potensi rata-rata berat daging buah 518 g/butir. Kemarau panjang pada tahun 2015 mengakibatkan berat daging buah turun pada tahun 2016, yaitu 433 g/butir, namun lebih tinggi dibandingkan kelapa DTA (371 g/butir) dan DMT (366 g/butir) sebagai varietas pembanding yang ditanam di lahan pasang surut. Jika berat daging buah kelapa dikonversi ke produksi kopra per hektar maka kelapa Dalam Sri Gemilang mencapai &gt; 3,0 ton kopra/hektar/tahun, sedangkan kelapa DTA dan DMT yang ditanam di lahan pasang surut masing-masing 1,6 ton dan 1,56 ton kopra/hektar/tahun. Hal ini menunjukkan bahwa Kelapa DTA dan DMT yang biasanya tumbuh baik dan berproduksi tinggi pada lahan kering, kurang adaptif pada lahan pasang surut.</p>

The increasing number of inhabitant in Sukacai village, Jiput – Pandeglang leads to the risen of clean water demand. However, along with the raising of demand, the groundwater availability has decreased. During the dry season, the water quality is poor and the rate of flow tends to be critical. As a consequence, the community is suffering from the scarcity of clean water supply for daily consumption and household necessity. This community service program aims to fulfill the needs of groundwater supply by applying the geophysical method, to recommend the depth of aquifer and construct the well of groundwater. The method is carried out using geo-electrical instruments to reveal the depth of aquifer as the source of groundwater. Another social approach is performed by educating the community about the optimization of well construction, as well as the effect of shallow and deep well construction towards the rate and quality of groundwater. The session has been wrapped with sharing and discussion. As a result, the authors recommend the depth of well construction is approximately 20 m for shallow well and 50 m for moderate well. The moderate well option is more recommended to avoid any contamination of pollution source as well as to maintain the flow rate during dry season.

The motivation of farmers in adopting groundnut cultivation technology, especially relay cropping patterns technology of corn and groundnut on dry land is relatively low. The study aims to determine the motivation of farmers in adopting groundnut cultivation technology that can increase farmers' incomes. The study was conducted in Labangka Subdistrict, Sumbawa Regency from December 2016 until August 2017 using survey approach. Data collection techniques carried out by observation, recording, and in-depth interviews with respondents. The sample population who adopted corn relay cropping pattern with groundnuts was 276 people. Determination of the sample of respondents was purposive as many as 40 people. Data were analyzed using descriptive analysis method. The results showed that the motivation of farmers in adopting technology was 79,29%. The adoption rate of groundnut technology components was 81,39%. Net income level or profitability of groundnut farming produced in the rainy season averages Rp 9.967.500/ha with an R/C Ratio of 2,65. Net income level or profitability of groundnut farming cultivated in the dry season averages of Rp 8.517.000/ha with an R/C ratio of 3,34. The R/C ratio value is more than 1 on groundnut farming that are cultivated in rainy season or in dry season are feasible to be cultivated because it can provide benefits and high income.

<em>Abstract</em> .—Pampangan District is a floodplain area, containing 21 distinct swamps characterized by seasonal shifts in the aquatic and terrestrial environment. During the wet season, the floodplain is covered by water with a depth of 1–4 m, whereas during dry season it becomes dry land. Local people living around the swamps have seasonal activities as fishers during the wet season and as rice farmers during the dry season. The average gross income is 15,041,000 Indonesian rupiahs (Rp) per wet season from fisheries and Rp 10,445,000 per dry season from rice farming. The swamps in Pampangan District are managed in an integrated manner based on local regulations. During the wet season, the water bodies are managed as common property resources, wherein all community members are allowed to exploit fish resources. During the dry season, the landowners claim their plots of rice field to cultivate rice. However, some small pools within the rice field areas are inhabited by several species of fish that are kept as broodstock to supply young fish for the next wet season.

AbstractAgriculture threatens biodiversity across the tropics, particularly in semi-natural grassland landscapes, where human populations are high, habitat is easily converted and agriculture is prone to intensification. Over the last 20 years intensive, commercial dry season rice cultivation has emerged as the dominant threat to the Bengal florican Houbaropsis bengalensis, a globally threatened bustard that breeds in the seasonally inundated grasslands of central Cambodia. Although floricans have been extensively monitored for 10 years, no socioeconomic research has been undertaken to examine how local livelihood activities interact with the florican. We conducted household questionnaires and focus groups in 21 villages in the Northern Tonle Sap Conservation Landscape to gather information on household demographics, rice farming and bird hunting in protected and unprotected areas of florican breeding habitat. We identified a significant increase in dry season rice adoption by local communities since 2005. Dry season rice cultivation was strongly associated with agrochemical use and rice fields directly overlapped with florican breeding habitat, reducing habitat availability throughout the breeding season. We identified a low but significant level of bird hunting in grassland households (8%) and revealed a demand for wild bird meat amongst local communities. Our findings suggest an urgent need for conservation interventions in unprotected farmland and emphasize the role of enforcement and community engagement in improving protection within protected areas. We highlight the potential of private sector initiatives such as the Sustainable Rice Platform in reconciling conservation and development for impoverished rural communities.
