Sloping Land

The slope of land in oil palm plantation areas is the one of the primary causes of low soil water content due to low rates of soil infiltration. Biomulch is one of the conservation methods that can be used to cover and shield the soil from weeds, prevent soil erosion, and increase the rate of soil infiltration. Arachis pintoi is a perennial, stoloniferous legume crop that has potentials to be used as biomulch. The objective of the research was to study the role of Arachis pintoi in increasing the rate of soil infiltration on a sloping land of oil palm plantation. The research was conducted on the slope land (22.8%) of the Bukit Kemuning Farmer Group, Mersam, Batanghari, Jambi, Indonesia (01036'21", 102057'11") from September 2017 to March 2018. The environmental design used in this study was a one-factor randomized block design (RBD) with five ground cover treatments, i.e. natural vegetation, Arachis pintoi, Centrosema pubescens, Pueraria javanica and Calopogonium mucunoides. The results showed that the average growth rate of A. pintoi was 2.47 cm per week, which was lower than the growth of other treatments. The root length of A. pintoi was 50.36 cm at 20 weeks after planting. A. pintoi can be used as biomulch; sloping land planted with A. pintoi had an infiltration rate of  49.30 cm per hour at 20 week after planting, i.e. an increase of 32.47% compared to the infiltration rate with the natural vegetation.Keywords: land cover crop, Centrosema pubescens, Pueraria javanica, Calopogonium mucunoides

Cocoa is commodities third largest foreign exchange earner after oil palm and rubber. In 2012 production totaled 833 310 tonnes of cocoa with an average growth of 1.56%. There are two major challenges in the development of the national cocoa industry, the increase in quantity (production and productivity) and quality. To support these efforts the role of research and development is needed to ensure that the procedures adopted are appropriate and fit. This study aims to study the role of research and development and other supporting factors in addressing the problems of the national cocoa. The study is in the form of survey respondents which are R&D institutes, universities and cocoa processing industry. The results show that there is a problem of national cocoa industry in all aspects, here the cultivation aspect is the biggest problem. The next aspects are mentoring, institutional, business scale, quality, policy, processing of intermediate products and processing of downstream products. The study also shows that there is still a lot of research results that can not be utilized by the cocoa industry, the rest has to be applied even if but only for a small scale so that the less significant. In the small and medium scale of cocoa enterprises, the equipment used is generally low capacity so inefficient. ABSTRAKKakao merupakan komoditas perkebunan penghasil devisa terbesar ketiga setelah kelapa sawit dan karet. Pada tahun 2012 produksi kakao tercatat sebesar 833.310 ton dengan rata-rata pertumbuhan sebesar 1,56%. Ada dua tantangan utama dalam pengembangan industri kakao nasional yaitu peningkatan kuantitas (produksi dan produktifitas) dan kualitas. Untuk mendukung usaha tersebut peran riset dan pengembangan (risetbang) sangat dibutuhkan untuk memastikan prosedur yang diterapkan sudah tepat dan sesuai.Studi ini bertujuan untuk mempelajari peran risetbang serta faktor pendukung lainnya dalam menjawab permasalahan kakao nasional. Studi ini berupa hasil survey terhadap responden (pelaku risetbang kakao) yaitu lembaga penelitian dan pengembangan, universitas serta industri pengolahan kakao. Hasil kajian menunjukkan bahwa permasalahan industri kakao nasional terdapat pada semua aspek, dimana aspek budidaya merupakan permasalahan terbesar. Aspek berikutnya adalah penyuluhan, kelembagaan, skala usaha, mutu, kebijakan, pengolahan produk antara dan pengolahan produk hilir. Studi juga menunjukkan bahwa masih banyak hasil riset yang tidak dapat dimanfaatkan oleh industri kakao skala besar, sisanya walaupun telah bersifat aplikatif tetapi hanya untuk skala kecil sehingga kurang signifikan. Pada industri usaha skala kecil dan menengah umumnya peralatan yang digunakan berkapasitas rendah sehingga tidak efisien.

Asystasia gangetica (L.) T. Anderson is a weed commonly found on oil palm plantations and can be used as cover crop for mature oil palm plantations due to its tolerance to shading. The use of cover crop is  a soil conservation technique to support sustainable availability of soil nutrients by reducing erosion and nutrients loss, particularly during the rainy seasons. This research aims to determine the roles of A. gangetica as cover crop for measures against erosion and nutrients loss in mature oil palm plantation. This research was conducted in oil palm plantation, Unit Rejosari, PT Perkebunan Nusantara (PTPN) VII, District of Natar, South Lampung Regency from August 2014 to April 2015. The research used split block design in randomized complete block design with two factors and six replications. The main plots were ridge terrace, namely with and without ridge terrace. The sub plots were cover crops, namely with and without cover crops A. gangetica. The results show that using A. gangetica as cover crops in mature oil palm plantations effectively minimized erosion and loss of organic C, N, P, and K by 95.7%, 93.4%, 96.0%, and 90.0 %, respectively. The use of cover crop became more effective when combined with ridge terrace and reduced erosion by 94.1% and loss of organic C, N, P and K by 99.1%, 99.2%, 90.0% and 98.5%, respectively.

<p>The integration of livestock with plantations is one of efforts to support livestock agribusiness. The large potential  land area can be used for the development of cattle. However, the low production, nutrient content and digestibility of natural grasses in the plantation are still an obstacle to increase cattle productivity. Therefore, the development of shade tolerant of forages is  one of the strategies to improve the quality and production of forages in the plantation area. This paper aims to review the role of <em>Stenotaphrum secundatum </em>as a shade tolerant forage in oil palm plantations in supporting cattle productivity. Biomass production of <em>Stenotaphrum secundatum </em>obtained was relatively high at 42,209 kg DM/ha/yr in oil palm plantations aged 3.5 years, estimated to be able to accommodate cattle of 11.8 AU/ha. With a moderate composition of nutrition, it can improve cattle growth performance with an average body condition score of 3.8. The livestock integration system by developing <em>S. secundatum </em>in the oil palm plantation area has a positive effect because it can reduce fertilizer and weeding costs of 4 million IDR/ha/yr. The average production of fresh fruit bunches (FFB) reaching 19.5 tons/ha/yr. It can be concluded that the role of <em>S. secundatum </em>in  oil palm plantations can support cattle productivity and increase palm oil production.</p>

Forest land conversion into oil palm plantation causes drastic ecological changes which influence various species in the ecosystem. Arthropoda, as one of the components of biodiversity, has important roles as herbivore, predator and parasitoid, and detritivore. This research was conducted in village of Runtu, Subdistrict of Arut Selatan, District of Kotawaringin Barat, the province of Central Kalimantan. Techniques of Arthropoda sample collection were pitfall trap, malaise trap, and sweep net conducted in two ecosystems. The two ecosystems were ecotone (transition between forest and oil palm plantation) and oil palm plantation. Research results showed that forest existence could increase the abundance of arthropoda. Abundance of Arthropoda in ecotone ecosystem was higher as compared to that in oil palm plantation. Populations of predator and parasitoid Arthropoda were higher in ecotone ecosystem.Key words: Arthropoda, detritivore, herbivore, oil palm plantation, predator, parasitoid
