Rural areas are still the mainstay target of exploration program from various stakeholders. Local communities as owners of rural areas often do not get proper returns from these explorations. One of the reasons is that the local community lacks of knowledge and not much involved in regional development. The success of rural area development is strongly influenced by the perception of the local community. Therefore in the development planning stage, perception should be one of the indicators that must be considered, as well as for eco-rural tourism planning. The aim of the study was to analyze the perception of local communities in eco-rural tourism planning from socio-cultural aspect. The research was carried out in Kerinci District, Jambi Province, using close-ended questionnaire instrument with One Score One Indicator Scoring System assessment pattern. The results showed that the local community stated the socio-cultural aspect was relevant to be developed in accordance with the values that had developed in the rural area. In addition of the interpretation that local communities were eager to jointly develop their rural areas into eco-rural tourism areas by meeting the indicators that have been formulated. This study concludes that local communities have great opportunities to develop their rural areas according to the concept of eco-rural tourism. ABSTRAKKawasan pedesaan merupakan kawasan yang sampai saat ini masih menjadi kawasan yang terus dikembangkan oleh berbagai pemangku kepentingan. Masyarakat lokal sebagai pemilik kawasan pedesaan seringkali tidak mendapatkan imbal balik yang sepadan dari eksplorasi tersebut. Salah satu sebabnya, karena masyarakat lokal masih kurang pengetahuan dan tidak banyak dilibatkan dalam pembangunan kawasan. Keberhasilan pembangunan kawasan pedesaan sangat dipengaruhi oleh persepsi masyarakat lokal itu sendiri. Sehingga dalam tahap perencanaan pembangunan sudah sepatutnya persepsi menjadi salah satu indikator yang harus dipertimbangkan, begitu juga untuk perencanaan ekowisata pedesaan. Penelitian ini bertujuan untuk menganalisis persepsi masyarakat lokal dalam perencanaan ekowisata pedesaan yang dilihat dari aspek sosial budaya. Penelitian dilaksanakan di Kabupaten Kerinci Provinsi Jambi, dengan menggunakan instrument berupa kuesioner tertutup dengan pola penilaian One Score One Indicator Scoring System. Hasil penelitian menunjukkan bahwa masyarakat lokal menyatakan aspek sosial budaya relevan untuk dikembangkan karena sesuai dengan nilai-nilai yang sudah berkembang pada kawasan pedesaan tersebut. Selain itu, Hal ini dapat dimaknai pula bahwa masyarakat lokal, mau untuk bersama-sama membangun kawasan pedesaannya menjadi kawasan ekowisata pedesaan dengan perlu memenuhi indikator-indikator yang telah dirumuskan. Studi ini menyimpulkan bahwa masyarakat lokal memiliki peluang besar dalam membangun kawasan pedesaannya sesuai dengan konsep ekowisata pedesaan.
农村地区仍然是各利益相关者勘探计划的主要目标。当地社区作为农村地区的所有者，往往没有从这些勘探中获得适当的回报。其中一个原因是当地社区缺乏知识，没有太多参与区域发展。农村地区发展的成功很大程度上受到当地社区看法的影响。因此，在开发规划阶段，感知应该是必须考虑的指标之一，也是生态乡村旅游规划必须考虑的指标之一。本研究旨在从社会文化层面分析乡土社区对生态乡村旅游规划的认知。研究在占碑省Kerinci区进行，采用封闭式问卷调查工具，采用一分一指标评分系统评估模式。结果表明，当地社区表示，社会文化方面的问题需要根据农村地区已形成的价值观加以发展。此外，还解释说，当地社区渴望通过满足已制定的指标，共同将其农村地区发展成为生态乡村旅游区。本研究的结论是，根据生态乡村旅游的概念，当地社区有很大的机会发展他们的乡村。[摘要]川山学步，川山学步，川山学步，川山学步，川山学步，川山学步，川山学步。Masyarakat当地sebagai pemilik kawasan pedesaan seringkali tidak mendapatkan imbal balik yang sepadan dari eksplorasi tersebut。Salah satu sebabnya, karena masyarakat本地masih kurang pengetahuan dan tidak banyak dilibatkan dalam pembangunan kawasan。Keberhasilan pembangunan kawasan pedesaan sangat dipengaruhi oleh persepsi masyarakat local to sendiri。sehinga dalam tahap perencanan pembangunan sutah sepatutnya persepsi menjadi salah satu指标yang harus dipertimbangkan, begitu juga untuk perencanan ekowisata pedesaan。Penelitian ini bertujuan untuk menganalis persepsi masyarakat local dalam perencananan ekowisata pedesaan yang dililihat dari讲社会budaya。Penelitian dilaksanakan di县Kerinci Provinsi占碑,dengan menggunakan仪器berupa kuesioner tertutup dengan普拉penilaian得分指标评分系统。Hasil penelitian menunjukkan bahwa masyarakat本地menyatakan讲社会budaya相关的untuk dikembangkan karena sesuai dengan nilai nilai yang sudah berkembang padada kawasan pedesaan tersebut。Selain itu, Hal ini dapat dimaknai pula bahwa masyarakat local, mau untuk bersama-sama membangun kawasan pedesaannya menjadi kawasan ekowisata pedesaan dengan permenuhi indicator - indicator yang telah dirumuskan。我的研究是，我的家乡，我的家乡，我的家乡，我的家乡，我的家乡

PT. Rajawali Nusantara Indonesia (PT RNI) is one of Stated-Owned Enterprises (BUMN) which is a holding company for the food industry. The primary industries of PT. RNI are agriculture and agroindustry, livestock and fisheries, as well as trade and logistics. In the internal scope of the company there is an activity, namely the submission of the procurement of goods and services, in that there is an applicant who wants to make a procurement proposal to meet the daily needs of his work.Procurement Submission at PT RNI, an employee must follow the flow with the provisions of large projects such as for example in building construction which of course have differences in terms of budget, level of urgency and method of submission. In addition, the applicant must also send a procurement request file which must go to the room unit concerned. A solution for creating a web-based internal goods and services procurement application, whose key feature is to submit a procurement request and have it validated by the verifier, can address this issue.The method used in making the application is the prototype method which consists of stages of communication, quick plan, modelling quick design, construction of prototype and deployment delivery and feedback.

Superior seeds are one solution for improving agricultural production in Nagan Raya Regency. The main problem that occurs is the difficulty of adoption by farmers due to a lack of information regarding the benefits that will be obtained through superior seeds. Therefore, communication plays a role in the process of spreading ideas and technology so as to accelerate the process of agricultural modernization. This study aims to identify and explain the communication of innovations made between agricultural and food policymakers and farmers in Nagan Raya Regency. The method used in this research was descriptive qualitative by extracting information from agricultural policymakers in Nagan Raya Regency consisting of farmer groups, agricultural extension workers, and employees of the Department of Agriculture and Livestock in Nagan Raya Regency. The results showed that superior seed innovation in Nagan Raya Regency still focused on three types, namely, Rice, Corn, and Soybeans (Pajale) which were imported from outside the region because there were not enough supporting resources for developing superior seeds independently in Nagan Raya Regency. The communication process carried out by agricultural policymakers in disseminating superior seeds to farmer groups includes (1) introduction of target audiences based on demographic aspects and socio-economic status of farmers; (2) designing messages that are appropriate to the target group's target audience; (3) determination of methods and techniques using comparative study methods, demonstration plots, and demonstration plots; and (4) selection of communication channels that are limited to face-to-face communication and limited use of audio-visual media.

优质种子是改善纳甘拉雅县农业生产的一个解决方案。出现的主要问题是由于缺乏关于优良种子将获得的利益的信息，农民难以采用。因此，传播在传播思想和技术的过程中发挥了作用，从而加快了农业现代化的进程。本研究旨在确定和解释纳甘拉雅县农业和粮食政策制定者与农民之间的创新交流。本研究采用描述性定性方法，从纳甘拉雅县的农业决策者(包括农民群体、农业推广工作者和纳甘拉雅县农业和畜牧业部的雇员)中提取信息。结果表明，由于缺乏自主培育优良种子的配套资源，纳甘拉雅县的优良种子创新仍主要集中在水稻、玉米和大豆(Pajale) 3种外来引进品种上。农业决策者在向农民群体传播优质种子时所进行的沟通过程包括:(1)根据农民的人口统计方面和社会经济地位引入目标受众;(2)设计适合目标群体目标受众的信息;(三)采用比较研究方法、示范小区、示范小区确定方法和技术;(4)沟通渠道的选择，仅限于面对面交流，视听媒体的使用有限。[摘要][摘要][摘要][摘要][摘要][摘要]这句话的意思是:“我的意思是说，我的意思是说，我的意思是说，我的意思是说，我的意思是说，我的意思是说，我的意思是说，我的意思是说，我的意思是说，我的意思是说，我的意思是我的意思。”Oleh karenanya komunikasi berperan dalam处理penyebaran ide和technologia sehingat处理modernisasperan。我是说，我爱你，我爱你，我爱你，我爱你，我爱你，我爱你，我爱你，我爱你。Metode yang digunakan dalam penelitian ini adalah desktitif kalititatii dengan menggali informasi dari pemangku kebijakan bidang tantani Kabupaten Nagan Raya yang terdiri atas kelompok tani, penyuluh pertanian, pegawai Dinas pertanian dan Peternakan Kabupaten Nagan Raya。Hasil penelitian menunjukkan bahwa inovasi benih unggul di kabupten Nagan Raya masih berfus paada tiga jenis komoditas, yiti, Padi, Jagung, dan Kedelai (Pajale) yang didatangkan dari luar daerah karena belum cukupnya sumya daya penembangan benih unjgul mandiri di Kabupaten Nagan Raya。(1)人口统计学、社会经济学、社会经济学、社会经济学、人口统计学、社会经济学、社会经济学、人口统计学、社会经济学、社会经济学、人口统计学、社会经济学、社会经济学;(2) merancang pesan Yang sessuai denan target kelompok sasan;(3) penetapan方法danteknik，杨孟古那坎方法研究图谱，demplot, dandemfarm;丹(4)彭古纳安媒体视听媒体terbatas。

Leachate waste from piles of garbage in the landfill (TPA) has a high concentration of Chemical Oxygen Demand (COD). High COD concentrations can cause a decrease in dissolved oxygen concentrations in the waters. Simple leachate treatment is carried out using the adsorption method with adsorbents derived from food waste. This research used Precipitated Calcium Carbonate (PCC) adsorbent from ale-ale shells. This study aims to evaluate the effect of particle size and calcination temperature variations on PCC yield and analyze the adsorption ability of PCC adsorbents in reducing COD concentrations. In addition, PCC was characterized using an infrared spectrophotometer (FTIR) and an X-ray diffractometer (XRD). Determination of COD concentration was carried out by permanganometric titration. The optimum PCC yield of 57.75% was obtained from Ale-ale shells with a particle size of 40 mesh with a calcination temperature of 800 ° C. The functional groups in PCC are C-O at wave numbers 1403 cm -1 , 873 cm -1 , and 713 cm -1 . XRD characterization showed the presence of a calcite phase with a high peak intensity at 2 𝜃 = 29.38 ° . The adsorption of organic matter on leachate by PCC (4.5 g/50 mL) with a stirring speed of 200 rpm for 240 minutes reduced the COD concentration of leachate from 1131.28 mg/L to 456.94 mg/L with an adsorption efficiency of 59.61%.
垃圾填埋场垃圾堆渗滤液(TPA)具有高浓度的化学需氧量(COD)。高COD浓度会导致水中溶解氧浓度降低。以食物垃圾为吸附剂，采用吸附法对渗滤液进行简单处理。本研究以啤酒壳为原料，采用沉淀碳酸钙(PCC)作为吸附剂。本研究旨在评价粒径和煅烧温度变化对PCC产率的影响，并分析PCC吸附剂降低COD浓度的吸附能力。此外，利用红外分光光度计(FTIR)和x射线衍射仪(XRD)对PCC进行了表征。采用高锰酸钾滴定法测定COD浓度。以粒径为40目、煅烧温度为800℃的Ale-ale壳为原料，PCC的最佳产率为57.75%，其官能团为C-O，波数为1403 cm -1、873 cm -1和713 cm -1。XRD表征表明，在2℃= 29.38°处存在高峰强度的方解石相。PCC (4.5 g/50 mL)在200 rpm搅拌240 min的条件下对渗滤液中的有机物进行吸附，使渗滤液中COD浓度由1131.28 mg/L降至456.94 mg/L，吸附效率为59.61%。

The Steam-Electric Power Station (PLTU) is one of the initiatives to meet the nation's current electricity requirements. The use of fuel for steam power plant is still dominated by fossil fuels such as coal. Even though domestic energy needs are met, steam power plant turns out to be a contributor to gas emissions that cause global warming, as well as a by-product in the form of fly ash which can cause environmental and ecosystem problems. Fly ash contains silica oxide (SiO 2 ) and aluminum oxide (Al 2 O 3 ) compounds which can be used as raw materials for synthesizing aluminosilicate-based materials such as geopolymers and zeolites. This study tested the characteristics and composition of chemical compounds in fly ash from Pulang Pisau’s power plant, Central Kalimantan. Characterization using X-Ray Diffraction (XRD) showed that peaks of quartz material dominated fly ash from Pulang Pisau’s power plant at 2θ=20.82°;26.61° and mullite minerals at 2θ= 31.2°;33.1°; 35.4°;39.2°;59.8°. The results of the chemical compound composition were tested using the ASTM-D3682-12 standard. Fly ash has a composition of 29.00% SiO 2 , 9.98% Al 2 O 3 , 13.75% Fe 2 O 3 , and 28.37% CaO. Fly ash from Pulang Pisau’s power plant is classified as type C fly ash, which can potentially be used as a source of aluminosilicate-based material synthesis.
