AbstractLontar (Borassus flabellifer L.)is a featured product of Timor Island that can be used for variuos purposes, including traditional drink. The improvement on the quality of distilled traditional drink is required to increase economic value and also community income in the same time through distillery system modification. The aim of this study was to find the influence of modified distillery (sok height) and flower type of sap on the traditional drink quality. The study was conducted using a fully randomized factorial design of four sok height variables (50, 100, 150, and 200 cm) and flower types sap variables (female, male, and mixed). Analysis of varian was used to determine variables and drink qualities relationship. The results showed that there was no interaction between sok height and flower type sap. The combination of variables (sok heightand flower type sap) influenced the traditional drink quality, including alcohol content, pH, total dissolved solids, color, flavor, and taste of the drink. A good alcohol content was resulted from the combination of a 200 cm sok high and mixed flower sap. The great pH of drink was obtained from male flower sap. The total dissolved solids, color, flavor, and taste were in the range of drinks requierment. The research results imply that for the distillation of traditional drink, a 200 cm high and mixed Lontar flowersap could be used to obtain a good quality of traditional drink product.AbstrakLontar (Borassus flabelliferL.) merupakan produk unggulan dari Pulau Timor yang banyak digunakan untuk berbagai keperluan, salah satunya adalah minuman tradisional (sopi).

The island of Timor with a dry tropical climate causes the emergence of a variety of local wisdom as a form of adaptation to environmental conditions. In West Timor, farmers use local knowledge as part of their ancestral heritage in the traditional farming system to improve the food security of family households. One form of local wisdom is a land and crop management system in which several types of food plants are planted simultaneously at the same planting hole (Salome). This study aims to prove the presence of biochar effects and residues as well as the age of defoliation on the results of corn in intercrops of Salome with several types of beans in dry land and to obtain suitable types of bean plants that are intercropped in Salome with corn. This research was conducted in July 2018 until July 2019 in the experimental garden of the Faculty of Agriculture, Timor University, Sasi village, Kefamenanu City District, TTU Regency. This research was conducted in two stages of planting, namely stage I, namely: planting in July to November 2018. Phase II was planting carried out in November 2018 to March 2019. This study used a 2 x 3 x 3 factorial randomized block design with 3 replications + corn monoculture and bean monoculture. The first factor is the use of biochar which consists of 2 levels, namely without biochar and the use of Biochar. The second factor is the age of corn dawn defoliation consisting of 3 levels, namely without defoliation, defoliation age 35 days after planting, defoliation age is 75 HST. The third factor is the type of upright type local beans consisting of 3 levels, namely: Vigna radiata L., Vigna umbellata L., Phaseolus vulgaris L., so there are 18 combinations. The results of the first phase of the research showed that the highest seed weight of corn produced a combination of treatment without biochar with defoliation age of 35 hst corn leaves in the monoculture system while in intercropping system produced by combination of biochar treatment, the defoliation age of 35 hst of corn leaves in the type of Vigna radiata L., The results of the second phase of the study showed that the combined treatment of using biochar residue, the defoliation age of 75 hst corn leaves produced the highest weight of corn seeds which were planted with intercropping system with mung bean types. The results of the first phase of the research showed that the highest seed weight of the bean plant was produced by a combination of treatments without biochar with type bean Phaseolus vulgaris L. in the monoculture system, whereas the intercropping system was produced by a combination of the use of biochar treatment without defoliation of corn leaves with the type of Phaseolus vulgaris L. beans, The results of the second phase of the study showed that the combination of the treatment of use without biochar residue, the age of defoliation of 35 HST corn leaves with the highest type of green beans in the intercropping system. Corn yield in the Salome intercropping system at the beginning of the use of biochar has decreased compared to control but has increased again when using biochar residue, the defoliation age of 35 hst corn leaves is better than without defoliation, all types of beans are suitable for planting with the Salome intercropping system. The types of Vigna radiata L. and Vigna umbellata L. are more suitable to be planted with the Salome intercropping system with corn at the beginning of biochar and pasa use when using biochar residues.

Sandalwood (Santalum album L.) is one of the native trees of Nusa Tenggara Timur Province because ithas high economic value and is the best endemic species in the world. The essential oil content in it has a very distinctive aroma and can be used to make various products such as handicrafts, wood carvings, incense, and oils for the perfume and cosmetics industry. Sandalwood is a semi parasitic plant whose life requires a host plant to obtain nutrients and water in the soil. There are many types of host plants that have been used, including casuarina equisetifolia, acacia mangium, sesbania grandiflora, alternanthera sp. and capsicum annum. In this research, sandalwood plants will be tested with the host plant Cymbopogon nardus, which from an economic point of view can provide benefits. Arbuscular Mycorrhizal Fungi (AMF) are a group of fungi from the phylum Glomeromycota which have mutualism symbiosis with higher plant root systems. AMF is able to survive on dry land. The purpose of this study was to analyze the effectiveness of AMF and the use of essential host plants to increase the growth of Sandalwood seeds in Timor Tengah Utara. In the parameter of high increase, the results of the Duncan test showed that the highest AMF treatment for agroforestry land and host chili plants was 19.01, which was different from AMF for agroforestry land within a host plant, Cymbopogon nardus namely 15.44. In the increase in diameter, the results of the Duncan test showed that the AMF treatment of agroforestry land and host chili plants had a significant effect on all treatments, namely 9.11. Duncan test results on plant biomass parameters showed that AMF treatment and host plants chili and lemongrass gave good treatment, namely 3.54 and 3.53 on shoot dry weight parameters and 3.75 and 3.42 root dry weight compared to control, namely 0.27, while at root and shoot ratio seed quality index, the seeds are suitable for use because they comply with the standard.

Sopi is an alcoholic drink distilled from Nira Lontar. For the indigenous people, dawan Sopi is a traditional drink, a cultural symbol and a tie for friendship between family members, for example as a traditional conversation starter and or media for solving problems. The problem that is happening in today's society is that people still tend to apply the conventional distillation process or their ancestral heritage, which requires a relatively longer time to produce the best quality sopi. Shok is a medium used from bamboo which is used for sopi distillation. The formulation of the problems in this study are i) How does the modification of the distillation medium (high shock) affect the quality of Timor sopi products, ii) How is the quality of Timor sopi products based on the length of storage time for sap of 24 hours and 12 hours of palm flower. This study aims to determine the effect of modified distillation media on the quality of Timor sopi products. To find out the quality of Sopi Timor products based on the length of time for palm sap to be stored. This research was carried out in Lanaus Village from September to October 2020. The palm sap used as research raw material was tapped from male lontar trees that grow around plantations and community forests in Lanaus Village, Insana Tengah District, TTU-NTT Regency. This study used a completely randomized design (CRD), which consisted of 2 factors. The results showed that there was no interaction between high shock treatment and sap storage time on parameters of sap alcohol content, sap acidity, sap soluble solids, sopi alcohol content, sopi acidity degree, and sopi soluble solids. The high shock treatment greatly affected the sopi alcohol content, this was indicated by the value of the sopi alcohol content at 12 hours of distillation at 3 meters high shock treatment where the yield reached an alcohol content of 48.33%. The duration of the sap storage has a significant effect on the quality of sopi, this is exemplified by the storage time of 12 hours in the morning giving the highest value of sap alcohol content and degree of acidity, while the soluble solids of the sap treatment of 12 hours in the afternoon give the highest soluble solids value. However, for the parameters of sopi alcohol content, degree of acidity of sopi and dissolved solids of sopi, the best holding time is the treatment time of 12 hours afternoon (shock height 3 meters). for 12 hours afternoon and with a shock height of 3 meters.

Based on the slope class, the shape of the area and the elevation of dry land in Nusa Tenggara, agricultural land in Noepesu Village is suitable for planting coffee plants with an agroforestry scheme. To overcome the problem of limited water, drip irrigation system technology can be applied. The use of drip irrigation as an agricultural technology in Noepesu village has been carried out by many farmer groups. Still, the installation process does not consider the pipe specifications (pipe length and pipe diameter) and the condition of agricultural land. This causes the service life of drip irrigation to be not long. If this continues, of course, it will increase system installation costs. To optimize service life, a hydraulics analysis method is needed for drip irrigation pipe network systems that take into account pipe specifications and agricultural land conditions.The hydraulics analysis of the drip irrigation network system determines the emitter’s water flow rate. The emitter flow rate forms a nonlinear equation known as the closed pipe equation. In the process of solving these equations, numerical methods can be used, specifically the Newton-Raphson method. This study focuses on applying the Newton-Raphson method to calculate the amount of water discharge from each emitter of the drip irrigation network system on the farmland of the Mutis Cemerlang Farmer Group in Noepesu Village. The drip irrigation system is designed with 250 nodes, 275 pipes, 26 loops, and 86 outlets divided into two sides, with the left side containing 84 outlets with one emitter and the right side containing 102 outlets with two emitters. The amount of water discharge for each emitter is 0,0008 ml/second≤Q≤2,6 ml/second for the left side and 0,001 ml/second≤Q≤1,1 ml/second for the right side, as determined by simulation calculations utilizing the Newton-Raphson method and Matlab software. The simulation results show that the amount of water discharge at each emitter is ideal in the first iteration because it has a discharge correction value (∆Q)≈0.
